219, Electric Heating,
121.36+, for means for heating a workpiece by directing to said workpiece ionized particles which had been created by an electrical arc drawn between two electrodes.
250, Radiant Energy,
281+, for mass spectroscopy methods and apparatus which ionize the particles through an electrostatic or magnetic field for separation of certain of the particles, subclass 396 for electron or ion beam deflection of focussing methods or apparatus and subclasses 423+ for ion generation methods and apparatus. 310, Electrical Generator or Motor Structure,
11, for dynamo-electric machinery employing a plasma to exert a mechanical force.
313, Electric Lamp and Discharge Devices,
62, for electrical space discharge devices provided with magnetic means for confining the path of the particles discharged and accelerating said particles; subclasses 359.1+ for discharge devices provided with means for generating and accelerating positive ions; subclasses 153+ particularly subclass 161, for space discharge devices having a magnetic field designed to influence a space discharge; subclasses 231.01+ for discharge devices having fluent material supply or flow directing means.
315, Electric Lamp and Discharge Devices: Systems,
111.01+, for a discharge device having means to supply a fluent material to a discharge area between discharge electrodes.
322, Electricity: Single Generator Systems,
48, for plasma generating means.
324, Electricity: Measuring and Testing,
300+, for means by which a substance may be ionized and the ionized particles moved through a magnetic field for observation so that the substance may be identified.
376, Induced Nuclear Reactions: Processes, Systems, and Elements,
100+, for processes and devices that utilize a gaseous or light element fuel material, the particles of which are electrically charged or excited to the point where they become highly ionized and the forces of repulsion of like nuclei are overcome to the end that thermonuclear fusion of such like nuclei is obtained or sought to be obtained. 417, Pumps,
48+, for electrical (e.g., ionic) or getter type pumps.
