Device And Control Procedure For Recovery Of Kinetic Energy In Railway Systems - Patent 8146513
OBJECT OF THE INVENTION The present invention, as stated in the title of this descriptive memory, relates to a device and control procedure for recovery of kinetic energy in railway systems, the object of which is to optimize the energy recovery made possible in trainbraking, allowing to inject in the corresponding electric grid a high-quality three-phase current, even in high grid voltage situations and using the pre-existing transformer in the substation supply connection. The invention produces the regenerationof energy in traction systems during the braking processes of trains associated to a DC catenary so that, with the device of the invention, when the voltage read in the catenary is greater than a specified value, energy is extracted to inject it in thecorresponding alternating current grid. This is done overcoming drawbacks of the state of the art such as the low efficiency with respect to the total available energy that could be injected in the grid and the voltage fluctuations produced in othersystems.BACKGROUND OF THE INVENTION Railway systems are known having a direct current catenary connected to a block of rectifier bridges that is in turn connected to the secondary winding of a transformer placed at the connection to the corresponding substation, the primarywinding of which being connected to a three-phase alternating current grid, connecting an energy harnessing device between the catenary and the secondary winding of the transformer, so that during braking of the trains a certain voltage is supplied tothe grid to allow making use of this energy. FIG. 12, corresponding to the state of the art, shows an arrangement existing in railway substations with DC catenary in which the catenary 20 is fed through uncontrolled rectifier bridges 40 that do not allow energy flow from said catenary 20to the AC grid 10, so that the railway unit or train, when braking, limits the voltage in the catenary 20 and the excess energy is burnt in a system installed for th
Tramway Transit System - Patent 8146509
The present application is based on, and claims priority from, Japan Application Number 2006-251652, filed Sep. 15, 2006, the disclosure of which is hereby incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tramway transit system in which vehicles having wheels equipped with for example rubber tires travel on a pre-established tramway, specifically relates to an actuator of an automatic steering mechanism of thevehicle. 2. Description of the Related Art A vehicle supported by wheels with rubber tires for a new transit system is generally provided with guide wheels so that the vehicle is steered to travel along the tramway, the steering being usually done mechanically through the guide wheelsengaging with a guide rail laid along the tramway. The mechanical guide mechanism is superior in point of view of safety and reliability, however, structure of bogies to which the wheels and driving mechanism thereof are mounted inevitably becomes complicated, is increased in weight, and resultsin increased running cost. Further, it is necessary to lay down the guide rail having enough strength to support the guide rails all along the tramway with high accuracy, so vast amounts of construction cost of the tramway is needed. In order to eliminate the above problem, a steering system not requiring a guide rail is proposed in Japanese Laid-Open Patent Application No. 2002-351544 (patent literature 1). The steering system of a tramway vehicle disclosed in the patent literature 1 is composed such that a plurality of on-ground devices which memorize and send out information necessary for operation of the vehicle are laid down along the wholelength of the track on which the vehicle travels, the control device installed on the vehicle emits signals based on the information sent out from the on-ground devices when the vehicle travels along the track, and the vehicle is steered by the steeringdevice
Workpiece Support System - Patent 8146510
The invention concerns a workpiece support system having a driven, circulating traction means; a stationary base frame; and at least one workpiece support that comprises a load carrier and a traction carriage. Workpiece support systems are used for transporting workpieces to various work stations, for example, in case of a production line. Workpiece support systems are known that in accumulation operation are driven by means of several advancingdevices with loosely driven workpiece supports. In this connection, the topside of the workpiece supports can always stay face up. These workpiece supports either move adjacent to one another (the workpiece supports are moved in one plane), above oneanother (the workpiece supports move in several planes), or in special cases are comprised of a combination system (the workpiece supports move, for example, in one plane and are lifted by a lifting system into further planes). For this purpose, foreach plane (exception: gravity roll table) and for each lifting system one drive is required, respectively. DE 1718135 U discloses a workpiece support system in which the workpiece support is configured as a carriage running on rails and connected to an endless transport belt. Once the carriages arrive at the end of the production line, they arereturned to the start of the production line. The return is realized by means of a bridge extending across the length of the production line. The bridge is arranged at a slant from the end of the line to the start of the line and is supported by twostands that are arranged at the end and the start of the line. The stands comprise lifts as a lifting system whose task it is to lift the carriages at the end of the production line to the return bridge and to lower them onto the production line aftercrossing the bridge. The workpiece supports thus move in different planes so that a lifting system must be used. The lifting systems each require a drive so that this configuration of a workpiec
Anti-extraction Safety Device For A Guidance Set Comprising Two Inclined Rollers Rolling On A Rail - Patent 8146512
This application is a National Stage completion of PCT/FR2007/002047 filed Dec. 12, 2007, which claims priority from French patent application serial no. 06-11296 filed Dec. 22, 2006.FIELD OF THE INVENTION This invention relates to an anti-extraction safety device for a guide assembly of a road vehicle guided by two inclined rollers rolling on a rail. Advantageously, the safety device of the invention may also perform the function of removing objects that may be located on the guide track and that may interfere with the guiding of the vehicle. The invention applies more specifically, but not exclusively, to urban public transport vehicles that are guided along a guide rail by means of a guide assembly comprising two guide rollers inclined to form a V shape.BACKGROUND OF THE INVENTION To ensure their guidance, guided urban public transport vehicles of this type have a guide assembly that permanently follows a continuous guide rail along the vehicle's entire route. This guide assembly comprises V-shaped inclined rollers that roll on inclined tracks provided in the upper part of the head of the guide rail; this guide rail comprises a rail head with projecting flanks, under each of which a recess is located. In order to ensure the safety of the vehicle and its passengers, it is essential that contact between the guide assembly, which is supported by the vehicle, and the guide rail--that is, between the guide rollers and the tracks on which theyroll--be ensured at all times when the vehicle is moving. To do this, the guide rollers are traditionally forced against the guide rail by an elastic return force, e.g., a spring arm. While this type of system is adequate for normal guiding situations, exceptional situations exist wherein stress that is greater than the elastic stress may be exerted on the guide assembly in the opposite direction. This stress lifts the guideassembly above the guide rail and extracts it from the guide area. The guide rollers are pulled pull aw
Dolly For A Conveyor Of An Automated Car Wash - Patent 8146511
Field of the Invention The invention relates to dollies for use in a conveyor for an automated carwash. In automated car washes, it is known to use endless chain conveyors of the type having "dollies" linked into the chain at regular intervals. The dollies are used to push vehicles along the conveyor by engaging a tread surface of a tire. Tofunction properly dollies must have tire engaging rollers and track engaging rollers. Typically the tire engaging rollers are larger in diameter than the track engaging rollers and are disposed in a center slot between opposite longitudinally extendingtrack rails. The dollies are connected into the continuous loop chain by a center link. U.S. Pat. No. 7,243,605 to Belanger et al. teaches a well known dolly. The dolly is formed of a long steel axle member in the form of a steel bolt having a threaded end which receives a nut. Mounted on the steel bolt is a center link whichis adapted to be connected into and form a part of an endless loop chain. The center link has an eccentric or off-center through-hole for receiving the steel bolt. Larger diameter tire engaging rollers are arranged on opposite side of the center linkand mounted on the steel bolt. Smaller diameter track engaging rollers are mounted on the steel bolt outboard of the tire engaging rollers for engaging the track rails of a conveyor track. At each of the most outboard positions, a stabilizing roller isarranged on the steel bolt. The entire assembly is being held together by a nut engaging the end of the steel bolt. The tire engaging roller is mounted on a radial bearing which interfits with a shouldered portion of the center link. The radialbearing interfits with bearing members disposed between the tire engaging rollers and the track engaging rollers and also including an off-center through-hole which receives the steel bolt. A set of radial bearings is provided for the track engagingrollers and these bearings coact with thrust bearings which are dis
Active Rail Transport System - Patent 8146506
The invention relates to a public rail transport system for individually transporting persons or goods in an automated manner on conventional rails without using a conductor, in which two automatically controlled conducting systems are arrangedsuch that individual cars that have an autonomous drive unit, brake, and steering mechanism, can be directed away from the rolling convoy (train), be decelerated, unloaded and/or loaded by merely changing the conducting system that mechanicallyinfluences the steering mechanism, lowering and lifting an associated scanning system, and can be redirected into a rolling convoy (train) at a different point after the speed of the individual cars has been adjusted to the speed of the convoy, whereinthe first conducting system, which comprises a first scanning system on each car and on the conventional rails, is used for providing continuous traction, and the second conducting system, comprising a second scanning system arranged next to the firstscanning system on each car and on the additional guidance rails installed on the side next to the conventional rails determines the direction when going over points. Such a transport system is known from patent DE 102 53 485 C1. It runs, like the Sprinter, without intermediate stop but in small units, automatically and individually, to each train station of the network. The individual units can beoptimised for different requirements. Thus, e.g., there can be units able to carry approximately 8 persons and one car, or, alternatively, goods. It combines the advantages of individual traffic on a motorway with the guidance of the rail. The resultis an automatic public means of transport without conductor whereby the existing rail is responsible for the steering. There is no need for overtaking since all cars are running with the same speed of, e.g., 200 km/h. Passengers or goods with a commondestination book a car to a specific train station, board and indicate their destination. If there
Pneumatic Mass Transportation System - Patent 8146508
FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not applicable.REFERENCE TO SEQUENCE LISTING Not applicable.BACKGROUND 1. Field of Invention The need is imperative to develop new forms of safe, alternative transportation that are supremely energy efficient. This invention represents a unique approach to pneumatic ground transportation for passengers and cargo. The system's powersource, method of propulsion and controls are exclusive elements to this invention. 2. Description of Prior Art Pneumatic passenger systems have been conceived to date. They are burdened with un-resolved issues inherent in pneumatic systems intended for use other than the transport of inanimate objects. Power sources and control of movement of prior arthave been problematic and present serious hindrances to practical development. Other system concepts are plagued with friction-related drawbacks due to car travel on slides and tracks within the tube. Pneumatic transportation of live passengers wasdeveloped into a prototype stage by Alfred Ely Beach in New York City in 1870. The use of a primitive power source (steam engine), the wooden tube, leather seals and lack of any practical movement control plagued the invention. The simultaneousdevelopment of the electric subway train then eclipsed all feasibility of Beach's efforts. The PneuTrain system detailed herein addresses and satisfies all drawbacks of prior art and incorporates new computer-based technology to solve the most criticalof issues--the starting, stopping, acceleration and deceleration of the system in cooperation of its very robust power source.SUMMARY OF THE INVENTION The PneuTrain is a unique supremely efficient rapid pneumatic mass transportation system. This system incorporates a free moving train of passenger cars through a tube infrastructure powered by a combination of differential air pressure forwardand aft of the train. The train cars will be cylindrical. They will contact the tube surface via guide wheels. Air

S This patent application is the national phase of PCT/EP2007/009684, filed Nov. 8, 2007, which claims the benefit of German Patent Application No. 102006054682.2, filed Nov. 17, 2006.FIELD OF THE INVENTION The present invention relates generally to crane rails for suspended crabs.BACKGROUND OF THE INVENTION Travel rails for suspended crabs are made from roll-formed sheet steel for cost and weight reasons. One example of such a travel rail is described in DE 41 19 868 A1. The rail forms a hollow bottom flange and a hollow top flange that areconnected to one another by a web. The web is configured as a single piece with one-half of the hollow top flange and one-half of the hollow bottom flange situated thereunder. The other halves of the top flange and the bottom flange consist of twoindividual roll-formed sheets that are then correctly positioned and joined to the part containing the web. These parts are then welded together. The welding costs are relatively high since, during the welding process, the parts must be correctly positioned and fixed in place by means of corresponding devices. Furthermore, the welding seams are located where there is a risk of weldingdistortions. It is particularly difficult to produce long, reliable MAG welding seams on relatively thin material. Due to its shape, the rail is also susceptible to bending during transport and has a low torsional rigidity.OBJECTS AND SUMMARY OF THE INVENTION In view of the foregoing, a general object of the present invention is to develop a rail with superior properties that can be manufactured more simply. The inventive rail consists of a single piece of roll-formed steel strip such that the handling of several parts is eliminated. After the roll-forming of the single sheet steel strip, the bending of the complete rail is finished. Devices forholding together any other parts in the correct position are not required. The handling during the welding process is also simplified because it is not r
Amusement Park Ride With Vehicles Pivoting About A Common Chassis To Provide Racing And Other Effects - Patent 8141495
1. Field of the Invention The present invention relates, in general, to theme or amusement park rides that simulate racing to guests while also guiding the location, speed, and position of the vehicles on the ride (e.g., the vehicles are not rider controlled such as gokarts or the like), and, more particularly, to systems and methods for selectively changing the position of vehicle bodies that are carrying passengers or guests such as by altering a position of two or more vehicles (e.g., in a set of racing vehicles)so as to change the lead and trail vehicles during the course of a ride. 2. Relevant Background Amusement parks continue to be popular worldwide with hundreds of millions of people visiting the parks each year. Park operators continuously seek new designs for thrill rides because these rides attract large numbers of people to their parkseach year. Racing rides are a genre or type of ride that is very popular with guests. In theme and other parks, in addition to high-speed or thrill portions of rides, many rides incorporate a slower portion or segment to their rides to allow them toprovide a "show" in which animation, movies, three-dimensional (3D) effects and displays, audio, and other effects are presented as vehicles proceed through such show portions. The show portions of rides are often run or started upon sensing thepresence of a vehicle and are typically designed to be most effective when vehicles travel through the show portion at a particular speed. As a result, it is desirable to provide a racing ride in which the speed, location, and orientation (e.g., face the riders toward a show or other display) of the vehicles can be controlled or guided, which generally rules out rider-controlledracing such as provided by go-karts and similar vehicles where the riders control their speed and location on a course. Guided or controlled vehicles are also desirable in many amusement park settings because they can be operated more safely to ensurethat t
Linear Motor Driven System And Method - Patent 8136453
This invention relates generally to systems driven by linear motors, and in particular to systems and methods of moving vehicles utilizing linear motors.BACKGROUND OF THE INVENTION In the past few decades, water-based amusement rides have become increasingly popular. Such rides can provide similar thrills to roller-coaster rides, with the additional features of the cooling effect of water and the excitement of beingsplashed. The most common water-based amusement rides are flume-style waterslides in which a participant slides along a channel or "flume", either on his or her body, or on or in a vehicle. Water is provided in the flume to provide lubrication betweenthe body/vehicle and the flume surface, and to provide the above-mentioned cooling and splashing effects. Typically, the motion of the participant in the flume is controlled predominantly by the contours of the flume (hills, valleys, turns, drops, etc.)in combination with gravity. As thrill expectations of participants have increased, demand for greater control of participants' movement in the flume has correspondingly increased. Thus various techniques have been applied to accelerate or decelerate participants by meansother than gravity. For example, a participant may be accelerated or decelerated using powerful water jets. Other rides use a conveyor belt to convey a participant to the top of a hill the participant would not otherwise crest on the basis of his orher momentum alone. For safety reasons, such techniques are generally used only on waterslides where the participant slides along the flume in a vehicle. However, such existing means of controlling the movement of a participant raise safety and comfort concerns even when he or she is riding in a vehicle. For example, a water jet powerful enough to affect the motion of a waterslide vehicle couldinjure the participant if he or she is hit in the face or back of the head by the jet, as might be the case if the participant falls out of the vehicl
Lap Bar Assembly With Locking Mechanism With Locking In Lap Bar And Grab Bar Positions - Patent 8132514
1. Field of the Invention The present invention relates, in general, to amusement park rides and passenger restraints in such rides and other implementations, and, more particularly, to a lap bar assembly for an amusement park ride providing locking in both a ride ordown position and in a released or up position to provide lap bar and grab bar functionality in an automated manner. 2. Relevant Background Passenger restraints such as lap bars are used throughout the amusement park industry to safely and securely restrain passengers within a seat of a vehicle. For example, many amusement park rides provide themed rides in which vehicles ridealong on one or more tracks, and the passengers are restrained from standing up or leaving the vehicle by a lap bar that is positioned across their laps or provided over their shoulders as an overhead or similar restraint. During loading, the lap bar istypically positioned against the passenger by a ride operator that is pressing a foot lever to allow adjustment of the position of the lap bar relative to the passengers. Once in position, the operator releases the foot lever or pedal to lock the lapbar in this ride or down position. When the ride is over, the vehicle may pass over a portion of the track with a release mechanism causing the lap bar to become unlocked from the ride position. The lap bar then may spring to an open or up position. There are a number of concerns with these conventional lap bar assemblies including the fact that these assemblies only lock in the ride or down position and not in the up position. In other words, existing lap bar assemblies are not useful assupports or grab bars during loading and unloading and will typically freely move when grabbed by a passenger for support, which can cause the passenger to lose balance or the bar to move quickly downward toward other passengers. Additionally,conventional lap bars typically only provide one locking position that is set manually by the ride operat
Amusement Park Ride With A Vehicle Drive That Decouples Upon Loss Of Power - Patent 8132513
1. Field of the Invention The present invention relates, in general, to amusement park rides such as dark rides that provide evacuation points upon loss of power, and, more particularly, to systems and methods for driving or propelling vehicles along a track in a dark orother amusement park ride so as to allow fewer evacuation points for vehicles on loss of power, e.g., by providing a drive or propulsion system that decouples from the vehicle upon loss of power allowing the vehicles to continue to travel to anevacuation point provided along the track. 2. Relevant Background Amusement parks continue to be popular worldwide with hundreds of millions of people visiting the parks each year. Many rides incorporate a slower portion or segment to their rides to allow them to provide a "show" in which animation, movies,three-dimensional (3D) effects, audio, and other effects are presented as vehicles proceed through such show portions. For example, a roller coaster may be designed such that in a show portion dinosaurs attack vehicles, meteors fly toward thepassengers, animatronic figures perform, and the like. The show may be designed based on the anticipated speed of the vehicle after it enters the show portion such that an effect such as 3D "attack" on the vehicle occurs precisely when the vehicle isadjacent to a portion of the display screens, speakers, and/or other show equipment. Other rides are designed such that the show includes jets, streams, and other water effects that require knowledge of vehicle position and speed to achieve desiredeffects such as water passing near passengers without striking the passengers or vehicle. Other rides are used to tell stories, and it is desirable to control the speed or pace of the vehicles during show sections of the ride so the passengers can enjoythe set, which may include special effects that are sensitive to or synchronized to vehicle speed (e.g., a multimedia presentation may actually be intentionally distorted such
Railroad Tie Plate Apparatus And Method - Patent 8132512
FIELD OF INVENTION The present application relates to railroad tracks, and more particularly to an apparatus and method for distributing railroad tie plates adjacent to the rails of railroad tracks.BACKGROUND The rails of a railroad track are usually secured to cross ties by spikes driven into tie plates, with the tie plates located between the rail and the tie, and the head of the spike overlapping the bottom of the rail. The tie plates blocklateral movement of the rails. Anchors are attached to the rail on either side of the tie to secure the rail against longitudinal movement. Railroad ties occasionally must be replaced due to wear. After a tie is replaced, tie plates must be provided between the rail and the tie so that the rail may be properly secured to the tie. Several references propose various systems for use in replacing tie plates. For example, U.S. Pat. No. 4,280,613, issued to J. K. Stewart on Jul. 28, 1981, describes a tie plate conveying and orienting system. U.S. Pat. No. 4,770,103, issued to F. Allmer on Sep. 13, 1988, describes a rail clamp. The rail clamp includes a pair of line-up wheels for engaging the inside edges of the rails. A pair of pivoting clamping arms, with each clamping armhaving a disk rotatably mounted to its end, engages the outside edge of each rail, just below the rail's ball. Movement of the clamping arms is controlled by hydraulic cylinders. Additionally, a stabilizer cylinder connecting a bridge crossing thechassis to the rail lifting assembly may either permit the rail lifting assembly to float to correspond with the rails, or may be locked in position. U.S. Pat. No. 4,733,614, issued to G. Mohr et al. on Mar. 29, 1988, describes a machine for repairing a railway track. The machine includes a main chassis having various devices for repairing a railway, mounted on a chain drive under arailway vehicle. A counter weight mounted to the chain drive, moving the opposite direction, counters the effects of inertia.
Material Handling System Including Dual Track Assembly And Method Of Operating Same - Patent 8127687
The present disclosure relates generally to a material handling system for a manufacturing line, and more particularly to a modular material handling system including a dual track assembly.BACKGROUND During a manufacturing process, a product is typically advanced through a plurality of manufacturing stations of a manufacturing chain. Specifically, the product is transported through each of the manufacturing stations along an articletransportation device. At each manufacturing station, a specific one of a plurality of tasks in the manufacturing process is performed. All equipment and other components necessary to perform the assigned task are positioned, and often permanentlyaffixed, at each manufacturing station. As a result, and dependent upon the number of tasks and the complexity of the manufacturing process, a manufacturing chain is typically a large structure that is permanently situated inside a manufacturingfacility. At least partially as a result of its permanency, a manufacturing chain is typically inflexible, such that modifying, removing, or replacing the manufacturing chain may be an expensive and time-consuming process. Therefore, even minorimprovements to the manufacturing process, such as, for example, changes to the equipment positioned at one manufacturing station, may be too expensive and time consuming to implement. Further, if the manufacturing process performed by the manufacturingchain becomes unnecessary, it may not be feasible to alter the manufacturing chain to perform a different manufacturing process. Ultimately, the manufacturing chain may only be cost effective in performing the specific manufacturing process for which itwas designed. As a result, the significant amount of costs and efforts to design and construct the manufacturing chain may be wasted. Another drawback with conventional manufacturing chains involves the article transportation system along which the products are transported. Since the products are typically carr
Suspension Type Robot Whose Robot Body Runs Along Traveling Rail - Patent 8122834
CROSS REFERENCES TO RELATED APPLICATION The present application relates to and incorporates by reference Japanese Patent application No. 2008-080775 filed on Mar. 26, 2008.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension type robot, and in particular, to a suspension type robot that comprises a traveling rail mounted, in a bridge form, between apical ends of support armsupport arms of a pair of posts and a robot bodysuspended from the traveling rail so as to be able to move along the traveling rail. 2. Description of the Related Art A suspension type robot is known as an assembly operation robot or the like in a factory, for example. Such a robot is disclosed, for example, in Japanese Unexamined Patent Publication No. 63-68382. This suspension type robot comprises a pairof posts positioned on a floor of a plant, a traveling rail mounted between the pair of posts in a bridge form, and a robot body (robot arm) supported by the traveling rail in a suspended form. The robot body moves back and forth along the travelingrail to perform operations. The posts of the suspension type robot allow the traveling rail to be mounted in merely a single predetermined direction, so that the position of the post is determined according to the mounting position of the traveling rail. Thus, there wasinsufficient flexibility in locating the posts when, for example, a change to the layout of the facility was required. The inventors of the present invention have conceived of a technical idea of displacing the position of the posts in relative to the traveling rail, by allowing an attachment portion of the traveling rail to be attachable to a support armsupportarm from predetermined directions. The support arm is provided to the apical end of each of the posts. However, moving the position of the post relative to the traveling rail causes the traveling rail to be temporarily unfixed from the posts, whichcould cause the traveling ra
