Mug With Stirring Mechanism - Patent 8152361
Various embodiments of the inventionare directed to a drinking apparatus with an integrated stirring mechanism to stir the beverage contained therein. Other embodiments are also described.BACKGROUND There have been various attempts at providing a drinking container with a stirring mechanism, to allow the user to stir the beverage without requiring the use of a separate stirring stick or spoon. In one category of such products, the stirringmechanism has been motorized or power operated. An example can be found in U.S. Pat. No. 5,720,552 issued to Schindlegger, in which a stirrer is rotatably attached to the surface of the base of the drinking glass. The stirrer is actuated by a motorinside the base. In an earlier attempt, as seen in U.S. Pat. No. 4,435,084 issued to Calhoun, et al., the stirring mechanism is adapted to be manually actuated from the lower end of a cup. While the former may be too complicated a solution, thelatter presents a difficulty for the user when the cup is resting in an automobile cup holder, as the user cannot easily access the bottom of the cup in that case. In another category of drinking containers with integrated stirring mechanisms, the stirrer is attached at the top of the drinking vessel, rather than at the bottom. For example, U.S. Pat. No. 5,586,676 issued to Lynd shows a drinkingcontainer cap that has a stirrer depending downwardly from its interior surface. Such a stirrer, however, is fixed in relation to the lid of the container, requiring that the lid be removed in order for the user to stir the beverage. In a more recenteffort, namely in U.S. Patent Application Publication No. 2003/0179647 issued to Simba, the stirring device is spring loaded and mounted to the top edge of a drinking vessel. The stirring device is shaped like a paddle and is submerged in the beveragecontent. The paddle pivots in response to the mechanism being operated by the thumb of the user's hand that is holding the vessel. This type of me
Storage Device For Laboratory Samples Having Storage Racks And A Shaker - Patent 8152360
The invention relates to a storage device for laboratory samples comprising at least one storage rack and a shaker drive. The invention also relates to climate controlled cabinets having such a storage device. In automated essays, e.g. in microbiology, samples are stored in so-called micro titer plates having a large number of small wells. Because of the large number of probes to be investigated, a large number of plates are used in a test run. Typically, the plates are stored in tower-shaped storage racks. Each storage rack is adapted to receive a plurality of micro titer plates (or similar laboratory samples) on top of each other. For certain applications, it is necessary to shake thesamples during certain time periods. EP 1443 101 describes a storage device in a climate controlled cabinet that comprises a shaker drive, which shakes a storage rack carrier. A number of storage racks, e.g. two, are mounted to the rack carrier. Since the storage racks arecomparatively high, undesired oscillatory movements of the upper ends of the storage racks can occur during shaking. This limits the shaking frequency and amplitude, makes it necessary to use a very sturdy setup, and leads to undesired noise andvibrations as well as to a shaking amplitude that is different for different storage locations.BRIEF SUMMARY OF THE INVENTION Hence, it is a general object of the invention to provide a storage device or a climate, controlled cabinet that allows an efficient shaking of even high storage racks. Now, in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the storage rack, in a first aspect of the invention, is manifested by the features that itcomprises a shaker drive, a rack carrier being driven by said shaker drive for performing a shaking motion with horizontal component, at least one storage rack arranged on the rack carrier, which storage rack comprises storage locations for a plur
Static Mixer - PDF
This application pertains to mixers and particularly static mixers having fixed position structural elements that are generally mounted within a length of pipe such that fluids passing through such pipe may be effectively mixed or blended with awide variety of additives. Such mixers have widespread use such as in municipal and industrial water treatment, chemical blending and chlorination/de-chlorination facilities. A highly effective commercially available mixer of this general type isdescribed in applicant's previous U.S. Pat. No. 5,839,828 issued Nov. 24, 1998 to Robert W. Glanville. The device disclosed in such patent operates in part by creating trailing vortices which produce effective mixing in the fluid stream. Theteachings of U.S. Pat. No. 5,839,828 are hereby incorporated into the present specification by specific reference thereto. Despite the availability of adequate mixing devices such as described in the above patent, there is a both a need and desire to achieve the same or better mixing outcome with lower head loss and to accomplish such in the shortest distancedownstream from the mixing device. A further object of this invention is the provision of such a device that accomplishes these objectives in a manner that is inexpensive, easy to fabricate from a wide variety of materials and operates in a trouble freemanner. These and other objects are accomplished by the provision of a static mixing device positioned in a conduit and within a fluid stream having a longitudinal flow direction with a passageway, comprising a plurality of mixing vane members forming aset thereof, said vanes spaced generally circumferentially equidistantly within a conduit and radially inwardly extending from a conduit internal wall surface towards the center of a conduit, each of said vane members including a generally oblong plateof planar extent with a generally straight base edge attached to an internal conduit wall and further including a leading edge upstanding
Disposable Shaker - Patent 8147120
The present invention relates to a disposable shaker with a cup-like base part and a cup-like cover part which are removably joinable together with an axial snap engagement or with a rotatable engagement.BACKGROUND OF THE INVENTION Disposable shakers are known in several embodiments. The Italian patent application RM94A000358 discloses a shaker consisting of several parts and formed by an upper cover part 1, a lower part 2 having a plurality of bins 4 for housing the single cocktail ingredients, and a membrane 3 which may befixed to the upper part of the lower part after having inserted said different cocktail ingredients in said single bins 4. The coupling between upper part and lower part takes place by means of pressure or a thread or bayonet closure. The shakerconsists of synthetic material. This embodiment has the disadvantage of requiring a long manipulation as well as a preliminary opening of the shaker before to prepare a cocktail. In fact said manipulation comprises a first step for opening the shaker,a second step for removing the membrane, a third step for closing again the shaker, a further agitation or shaking step, and a last shaker opening step in order to drink the prepared cocktail. Therefore are considered drawbacks the manual removing ofthe membrane as well as the temporary access to the bins 4 before the step for closing again the shaker, wherein during said free access time there is obviously the improper possibility for thirds to introduce undesirable substances in said bins. The IT-A-1.298.721 discloses a similar disposable shaker in which in the base part thereof is removably housed a multibin container. This embodiment has the same drawbacks of the shaker disclosed by the Italian patent application No. RM94A000358 with additionally the disadvantage of requiring an additional component, that is a removable multibin container and, therefore, of requiring a greater quantity of synthetic material and higher costs. The document FR-A-2 751
Covering Structure Of A Mixer - Patent 8147126
1. Field of Invention The invention relates to a mixer structure and, in particular, to a covering structure of a mixer. 2. Related Art As shown in FIG. 11, the conventional covering structure of a mixer has a fixed ring 2 fixed around the stirring bar at the bottom surface of the head 1 of the mixer. The lower section of the outer ring surface of the fixed ring 2 is extendedwith a protruding edge 3. A striding ring 6 protrudes from the top edge of the inner ring surface of a rotating ring 5. The rotating ring 5 is mounted on the upper surface of the protruding edge 3 using the lower surface of its striding ring 6. Thebottom surface of the rotating ring 5 is fixed with a connecting ring 7. The lower part of the connecting ring 7 is further soldered with a protecting mesh 8. A protecting cover 9 is connected to the neck part of the mixer using its back. When theoperator pushes or drags the protecting mesh 8 sideways, the rotating ring 5 rotates along the protruding edge 3 of the fixed ring 2. When the protecting mesh 8 rotates with the rotating ring 5 into the protecting cover 9, it is in an open position. Onthe other hand, when the protecting mesh 8 rotates out from the protecting cover 9, it is in a closed position. However, in the above-mentioned covering structure of the mixer, the connecting ring 7 is fixed on the bottom surface of the rotating ring 5 using several screws 71. The connecting ring 7 thus can rotate with the rotating ring 5. In such aconfiguration, one needs to use hand tools to install or uninstall the connecting ring 7. This is very complicated and time-consuming. It is difficult for the user to uninstall the connecting ring 7 and the protecting mesh 8 for cleaning. Moreover, the mixer produces vibrations. Therefore, when screws 71 are used to connect the covering structure on the connecting ring 7, they may become loose and fall into the food in the mixing buckle. This is very dangerous for consumers. Besides, the rotating ring
Apparatus With Automatic Balancing For Mixing Paint Disposed In Containers Having Different Configurations - Patent 8147123
The present invention relates to the mixing of fluid dispersions and more specifically to apparatus and methods for mixing paint disposed in a container having either a cylindrical or a square shape. As is well known, solids in fluid dispersions, such as paint, tend to settle in a downward direction through the force of gravity. Fluid dispersions disposed in containers for commercial sale are typically mixed in the containers before theyare used by the purchasers. Many fluid dispersions can be facilely mixed in a container by manually shaking the container. Other fluid dispersions, however, such as paint, are more difficult to manually mix in a container and, thus, are often mixed inthe container using a machine that shakes, rotates, vibrates or otherwise moves the container. A variety of different types of mixing machines are known for mixing fluid dispersions disposed in containers. One type of mixing machine that is commonly used to shake individual containers is known as a vortex mixer. In a vortex mixer, thecontainer containing the dispersion is rotated around at least one axis. Typically, the container is at least rotated about its own vertical axis. Examples of conventional vortex mixers include those disclosed in U.S. Pat. No. 3,542,344 toOberhauser, U.S. Pat. No. 4,235,553 to Gall, and U.S. Pat. No. 4,497,581 to Miller, all of which are hereby incorporated by reference. Conventional vortex mixers such as these can only accommodate cylindrical containers. Such vortex mixers cannotproperly accommodate generally square or rectangular containers. Paint, however, is beginning to be packaged in generally square or rectangular containers. Moreover, some of these containers have integral handles formed in their bodies. A commercialexample of a generally square container with an integral handle molded in the body thereof is the TWIST & POUR.TM. container sold by The Sherwin-Williams Company, who is the assignee of the present application. Anothe
Pre-mixing Apparatus For A Turbine Engine - Patent 8147121
Exemplary embodiments of the invention pertain to the art of turbomachine combustion systems and, more particularly, to a pre-mixing apparatus for a turbomachine combustor. In general, gas turbine engines combust a fuel/air mixture which releases heat energy to form a high temperature gas stream. The high temperature gas stream is channeled to a turbine via a hot gas path. The turbine converts thermal energy fromthe high temperature gas stream to mechanical energy that rotates a turbine shaft. The shaft may be used in a variety of applications, such as for providing power to a pump or an electrical generator. In a gas turbine, engine efficiency increases as combustion gas stream temperatures increase. Unfortunately, higher gas stream temperatures produce higher levels of nitrogen oxide (NOx), an emission that is subject to both federal and stateregulation. Therefore, there exists a careful balancing act between operating gas turbines in an efficient range, while also ensuring that the output of NOx remains below mandated levels. Low NOx levels can be achieved by ensuring very good mixing of the fuel and air. Various techniques, such as Dry-low NOx (DLN) combustors including lean premixed combustors and lean direct injection combustors, are utilized to ensure propermixing. In turbines that employ lean pre-mixed combustors, fuel is pre-mixed with air in a pre-mixing apparatus prior to being admitted to a reaction or combustion zone. Pre-mixing reduces combustion temperatures and, as a consequence, also reduces NOxoutput. However, depending on the particular fuel employed, pre-mixing may cause auto-ignition, flashback and/or flame holding within the pre-mixing apparatus. In turbines that employ lean direct injection (LDI) concepts, fuel and air are introduced directly and separately into a combustion liner arranged at an upstream end of a combustor prior to mixing. However, some systems that employ LDI conceptsexperience difficulties in rapid and uniform mix
Dispensing And Mixing Tip For Reactive Componets - Patent 8147122
The present invention is a tip for mixing a plurality of components and for dispensing the mixture. The tip is particularly suited for use with a bulk supply of the components. The tip is further particularly suited for the mixing anddispensing of reactive materials.BACKGROUND OF THE INVENTION Tips that both mix and dispense materials are known in the art. For example, U.S. Pat. No. 5,249,862 discloses such a tip which is particularly suited for the mixing and dispensing of dental impression materials. In may circumstances, aplurality of pre-mix components are housed separately, such as in separate areas of a single bulk storage device. When a quantity of the mixture of the components is needed, the separate components are caused to flow into the mix tip where they aremixed and then dispensed therefrom. This may be the case for example, when a base and a catalyst are employed in a dental impression material. This type of mix tip is often associated for use with a powered bulk storage device that imparts torque to astator within the mix tip, causing the stator to rotate to effect mixing and advancing of the mixed components through the tip to be dispensed. As noted in the '862 patent, cross-contamination between the components should be avoided as much as possible until desired. Any cross-contamination between the components in the bulk storage device itself could block the output of the deviceor prematurely react the components. Neither situation is normally desirable. A need exists therefore, for a mixing and dispensing tip for a plurality of materials, particularly a tip designed to be employed with a bulk storage device. Such a tip should help prevent unwanted cross-contamination within the bulk storagedevice or its outlet channels. The tip should be improved with respect to its ability to intimately mix the components.DISCLOSURE OF THE INVENTION A tip for mixing and dispensing a plurality of components has extended feeder channels that individually
This invention relates to a lid for a container of a blender and its method of operation. More specifically, this invention relates to a lid which reduces turbulence in the container as a food product is being blended in the container.BACKGROUND ART Food products are often mixed in the container of a blender or food processor. A cover or lid, which is often made of a flexible rubber-like material, is placed on the container, and blades positioned in the bottom of the container mix thefood, at least a portion of which is a liquid material. At times, particularly when the container is nearly full of a liquid material, the agitation of the blades causes the liquid to swirl which could result in a great deal of turbulence in thecontainer. Such turbulence can cause the container to rock or sway and can cause the cover to undulate. If allowed to continue, such could result in the container actually falling off of the base of the blender or the cover coming loose from thecontainer allowing the contents to spill out of the container.DISCLOSURE OF THE INVENTION It is thus an object of one aspect of the present invention to provide a cover for a blender container which reduces turbulence in the container. It is an object of another aspect of the present invention to provide a cover for a blender container, as above, which minimizes the possibility of the container wobbling and the cover undulating. It is an object of a further aspect of the present invention to provide a cover for a blender container, as above, which will remain attached to the container under the most severe mixing conditions. It is an object of yet another aspect of the present invention to provide a cover for a blender container, as above, which will enable the container to be maintained on the base of the blender under the most severe mixing conditions. It is an object of an additional aspect of the present invention to provide a method of minimizing the turbulence that might be created in a blender
Apparatus For Homogenizing Powder - Patent 8147118
PRIOR ARTCross-Reference to Related Application This application is a 35 USC 371 application of PCT/EP 2007/055800 filed on Jun. 13, 2007.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for homogenizing powder, in which the powder is then dispensed into a container, such as a capsule or a package. 2. Description of the Prior Art An apparatus for homogenizing powder is known from the prior art, such that an agitator mechanism, for instance, is provided, having a rotating agitator that plunges into the powder and is rotated. By means of the rotating agitator, the attemptis made to break up so-called powder bridges. However, especially with very fine-grained powder such as medications or the like, it is still possible for the powder to stick together and clump. Moreover, agitator mechanisms require a relatively largeamount of space.ADVANTAGES AND SUMMARY OF THE INVENTION The apparatus for homogenizing powder according to the invention has the advantage over the prior art that while having a simple construction and being economical to manufacture, it enables reliable homogenization of a powder. In particular,unwanted powder concentrations can be broken up with a high degree of process safety. In particular, homogenization can be done in a way that makes for very gentle product handling, as is necessary particularly for medications or the like. Moreover,the power can be adapted flexibly to different powdered products. This is attained according to the invention in that the apparatus for homogenizing powder includes a drive device and a homogenization unit. The drive device moves the homogenizationunit back and forth at least in a horizontal direction. The homogenization unit includes many rod-shaped elements, which plunge at least partway into a powder that is to be homogenized. Thus by means of the driven homogenization unit, the rod-shapedelements are moved back and forth in a horizontal direction, so tha
Convenience Nectar Mixing And Storage Devices - Patent 8147119
The present invention relates to a device to be used to mix and store sugar water (nectar) for nectar type bird and butterfly feeders. The present invention allows for conveniently measuring, mixing and storing the precise proportions of sugarand water required for hummingbird, oriole and butterfly nectar feeders.BACKGROUND OF THE INVENTION The popularity of nectar type feeders (sugar-water) for the feeding of hummingbirds, orioles and even butterflies is ever increasing. At the same time, there is extensive research showing that certain sugar to water proportions are preferred bythe birds and butterflies, these proportions being more or less equivalent in sugar content with their natural food sources. As anyone in the nectar feeder manufacturing and or bird feeding specialty retailing business will attest, customers (consumers) are constantly asking and needing to be reminded about correct nectar (sugar to water proportions) recipes and howthey should prepare the nectar for their feeders. Further, there are increasing concerns among bird feeding authorities that feeding birds with nectar that is disproportionately sweeter (higher sugar to water ratio) than their natural food sources mayhave an adverse effect on the birds health if used over the long term. There are similar concerns about using the commercially available nectar concentrates which have concentrated artificial coloring and/or flavorings. There is clearly a need for a device to simplify the mixing of sugar and water to arrive at the correct sugar to water proportion for hummingbird, oriole and butterfly nectar feeders. At the present time, the currently recommended sugar towater proportions are: Hummingbird Feeder Nectar--1 part table sugar to 4 parts water Oriole Feeder Nectar--1 part table sugar to 6 parts water Butterfly Feeder Nectar--1 part table sugar to 9 parts water These nectar (sugar to water) proportions are currently recognized as being proportionally equivalent in sugar content as th
Water Tank Deicing Mixer - Patent 8147117
1. Field of the Invention This invention relates to methods and apparatus to mix thermally stratified potable water supplies to prevent freezing. 2. Description of the Related Art When a large capacity tank is underutilized, differential thermal conditions in the tank can cause the contents to stratify in thermoclines, where warmer layers of water meet cooler layers. If, as is often the case, a tank with stratifiedcontents is both filled and emptied from a limited portion of the tank, water supplied by the tank will be from recently filled, fresher strata, while the remaining strata in the tank may age, unused and relatively undisturbed. For non-insulated orunder-insulated tanks in colder regions during winter months, the aging, unused strata of water in such tanks may lose sufficient heat to freeze. When ice forms in a water storage tank, the effective liquid capacity of the tank is reduced by the volumeof ice in the tank. If a sufficient volume of ice is formed, the effective liquid capacity of the tank may be reduced by such an amount that it is not sufficient for water supply needs. Managers of water supply systems, such as municipalities, have employed various means to minimize formation of ice in water supply tanks, with varying degrees of success. In some systems, heating is used to prevent ice formation. In some suchsystems, water is heated. In some cases, liquid water from the tank is pumped and circulated through a heat exchanger to raise its temperature. In other cases, at least some of inflowing water is heated during filling of the tank. In yet other cases,steam is injected into the liquid water in the tank to raise its overall temperature. Such water tank heating systems are expensive and require considerable maintenance. In other systems, small sparging bubbles are provided to water in lower portions of the tank, exchanging heat from the air trapped in the bubbles to the water surrounding them as the bubbles rise through the tank. If the

The mixture ismanufactured to form synthetic leather containing the solid powder material, enhancing the variation of the synthetic leather. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a mixing device of the present invention; FIG. 2 is a perspective view of the mixing device of the present invention; FIG. 3 is a cross-sectional view of the mixing device of the present
Electromagnetic Axial Agitator - Patent 8142067
Thisapplication is a National Stage Application of PCT/Es2007/000061, filed 7 Feb. 2007, and which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above disclosed application. The present invention refers to an apparatus which axially stirs solid and/or liquid and/or gaseous substances individually or jointly. This invention is especially designed for laboratory use, industrial and/or domestic applications requiring this kind of axial stirring in order to mix or homogenize substances and/or carry out extraction processes. The present invention refers to the field of stirring and/or mixing and/or homogenization and/or substance extraction.BACKGROUND OF THE INVENTION Nowadays, most chemical analysis methods require the stirring of samples to obtain a proper homogenization, fluidization or mixing of all the substances in that sample, or to carry out extraction processes of some of the constituents of thesample. Stirring apparatuses currently used perform orbital stirring, rotational stirring, vibration stirring, swinging stirring, magnetic stirring, propeller stirring and pendular stirring. Orbital stirring (WO86/00995, US005558437A) consists of making the sample follow a circular or elliptical orbit and selecting its frequency, that is to say, the number of complete orbits per second. Rotational stirring (ES188622) consists of rotating the sample on an imaginary rotation axis which contains it. Vibration or vortex stirring (ES2160401T3), (U.S. Pat. No. 4,883,644, U.S. Pat. No. 4,305,668, US2005/0180258) is generated through an orbital stirrer-like movement with high frequency, having said stirrer a very small orbit radius (usuallyless than 1 centimeter) thus generating the vibration transmitted by direct contact on the container base containing the sample. Swinging stirring or swaying movement (ES219812Y) consists of making a platform oscillate alternately around an axis containing said platform.
