STATEMENT OF CLASS SUBJECT MATTER
This class includes, where not provided for elsewhere:
A. Processes (1) involving the use of electrolysis (as providedfor in Class 205); (2) of preparing or purifying compounds or elementsinvolving chemical reaction brought about by electrical or waveenergy in a magnetic field; (3) of treating materials involvingchemical reaction brought about by wave energy; (4) of preparing orpurifying compounds or elements involving chemical reaction broughtabout by an electrostatic field or electrical discharge; (5) involvingthe use of electrophoresis or electro-osmosis; (6) of treating aliquid (a) to separate or purify the liquid using electric and magneticfields simultaneously, (b) to separate or purify the liquid using anelectric field, or (c) using a magnetic field to obtain some effectother than mere separation or purification of the liquid; (7) involvingcoating, forming, or etching by the use of sputtering; and (8) involvingcoating by the use of vacuum arc discharge. (See Subclass References tothe Current Class, below.)
B. Products solely disclosed as made by a process under (A).For exceptions, see Lines With Other Classes and Wtihin This Class,Exceptions, below.
C. Apparatus for carrying out the processes set forth under(A) except the apparatus used to carry out the wave energy treatmentprocesses provided for in Class 204; such apparatus is providedfor elsewhere. (See Lines With Other Classes, below.)
D. Electrolyte compositions specialized for use in electrolyticprocesses or methods of preparing the compositions.
(1)Note. A list of superiority of several composition classesappears elsewhere. See Lines With Other Classes below.
(2)Note. Although the processes described above in (A), items(6), (7), and (8), do not involve strictly chemical changes, theyare in some respects closely related to other portions of the classand so have been included here.
(3)Note. Processes involving purely thermal actions of electricalphenomena or wave energy are not included in this class.
(4)Note. Class 204 provides for the combination of electricaland wave energy processes as described in (A) above with subsequent:(1) conventional treatments such as filtering, distilling, washing,and other methods of separating or concentrating products from theprevious Class 204 operation or (2) mere admixing of products fromthe previous Class 204 operation to form a desired end product.Where a subsequent step significantly modifies a composition, product,or article made by the previous Class 204 operation, the combined processis generally provided for elsewhere and is cross-referenced in Class204, where necessary.
(5)Note. The combination of an electrical or wave energy operationas described in (A) above with a preceding method, such as treatmentof material to prepare it for the electrical or wave energy operation,is provided for in Class 204. When a method preparatory to a Class204 operation is claimed, per se, and is not provided for elsewhere,it may be classified in Class 204.
