Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 310: Electrical Generator Or Motor Structure

This is the residual class for all subject matter, not elsewhere classified, relating to electrical generator or motor structure.

Subclass 311: Piezoelectric elements and devices
Subclass 316.02: Traveling wave motor
Subclass 317: Input circuit for mechanical output from piezoelectric element
Subclass 323.02: Motor producing continual motion
Subclass 323.03: Traveling wave motor
Subclass 328: With mechanical energy coupling means
Subclass 332: Multimorph
Subclass 333: Shear or torsional type
Subclass 339: Voltage, spark or current generator
Subclass 359: More than one poling direction (e.g., Rosen transformer)
Subclass 366: More than two

Class 359: Optical: Systems And Elements

Optical elements included in this class are: Lenses; Polarizers; Diffraction gratings; Prisms; Reflectors; Filters; Projection screens; Optical Modulators; Optical Demodulators. Among the optical systems included in this class are: Compound lens systems; Light reflecting signalling systems (e.g., retroreflectors); stereoscopic systems; Binocular devices; Systems of lenticular elements; Systems involving light interference; Glare reducing systems; Light dividing and combining systems; Light control systems (e.g., light valves); building illumination with natural light; Systems for protecting or shielding elements; Optical systems whose operation depends upon polarizing, diffracting, dispersing, reflecting, or refracting light; kaleidoscopes. Further included are certain apertures, closures, and viewing devices of a specialized nature which involve no intentional reflection, refraction, or filtering of light rays. This class also includes optical elements combined with another type of structure(s) to constitute an optical element combined with a nonoptical structure or a perfection or improvement in the optical element.


Class 417: Pumps

This is the general class for the pumping of fluids, and includes the pumping of slurries, fluent material and the like if handled in a manner not inconsistent with the handling of fluids. A pump is defined as means to move a fluid by taking it from one place or location and moving it to another place or location different from whence it came, the pump, therefore having an inlet and an outlet for the pumped fluid which are separate and distinct. The pumping of the fluid is generally accomplished by action thereon of a mechanical member (eg. piston) or by contact or entrainment with another fluid (eg. jet pumps). Also, the pumping may be accomplished by the direct action on the pumped fluid of an electric or magnetic. This class is the residual home for the formation of a vacuum in an enclosed space by a gettering action; a getter being a material which when placed in an enclosed space reduces the gas or vapor content of the space either by a chemical or physical action. Also, included are those devices and processes in which the fluid is ionized to permit or enhance the gettering action. These devices are often termed "getter-ion pumps".

Subclass 53: PROCESSES
Subclass 322: Magnetostrictive chamber

Class 252: Compositions

(A) Compositions of matter, having or not having structure, physical form or heterogeneous arrangement of components and for which there is no provision elsewhere. (B) Packages of such compositions, or other articles which include such compositions for which there is no provision elsewhere. (C) Processes of making, or peculiar to making, such compositions and for which there is no provision elsewhere. (D) Apparatus for use in or peculiar to such processes and for which there is no provision elsewhere.

Subclass 62.9PZ: Lead, zirconium, titanium or compound thereof containing

Class 501: Compositions: Ceramic

This is the generic class for: Glass compositions and compositions for making glass, i.e., glass batch compositions, devitrified glass-ceramic compositions and processes for producing such compositions. These compositions may be regarded as thermoplastic compositions. Refractory compositions comprising primarily earthy, inorganic materials, and/or elemental carbon. Fired clay containing compositions in the nature of porcelain, earthenware, and similar materials. These compositions may be regarded as thermosetting compositions

Class 264: Plastic And Nonmetallic Article Shaping Or Treating: Processes

Processes for molding, casting, or shaping of nonmetallic materials to produce articles. Liquid or melt comminuting of materials other than glass or metal. Uniting or compacting of bulk or randomly assembled particles. Furnace Lining or repair. Melt shaping in the absence of a mold or shaping surface, e.g., spheroidizing of particles. Working or treatment of nonmetallic materials not otherwise provided for.

Subclass 614: Of electrical article or electrical component (i.e., not insulator, per se)
