Patent Summary

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

Class 427: Coating Processes

This is the generic class for: A. applying or obtaining a coating on a surface. The coating may be hard or soft, permanent or transitory, supplied solely by extraneous materials or supplied wholly or in part by the base material. B. impregnating a base by causing a coating material to extend or penetrate into the base material, or into the interstices of a porous, cellular or foraminous material. C. taking preparatory treatments of the base material, subsequent treatments of the coated base material and other ancillary noncoating operations claimed, per se, processes limited to etching for making a base more compatible with, or adherent to, the coating wherein the base is the substrate (work) onto which a coating is applied are included.

Subclass 249.3: Fiber or fibrous web or sheet base (e.g., strand, filament, fabric, cloth, etc.)
Subclass 250: Metal coating
Subclass 255.24: Fiber or fibrous web or sheet based (e.g., strand, filament, fabric, cloth, etc.)
Subclass 255.5: Moving the base
Subclass 255.7: Plural coatings applied by vapor, gas, or smoke
Subclass 566: Electron irradiation (e.g., e-beam evaporation, etc.)
Subclass 585: Chemical vapor deposition (e.g., electron beam or heating using IR, inductance, resistance, etc.)

Class 204: Chemistry: Electrical And Wave Energy

This class includes, where not provided for elsewhere: A. Processes (1) involving the use of electrolysis (as provided for in Class 205); (2) of preparing or purifying compounds or elements involving chemical reaction brought about by electrical or wave energy in a magnetic field; (3) of treating materials involving chemical reaction brought about by wave energy; (4) of preparing or purifying compounds or elements involving chemical reaction brought about by an electrostatic field or electrical discharge; (5) involving the use of electrophoresis or electro-osmosis; (6) of treating a liquid (a) to separate or purify the liquid using electric and magnetic fields simultaneously, (b) to separate or purify the liquid using an electric field, or (c) using a magnetic field to obtain some effect other than mere separation or purification of the liquid; (7) involving coating, forming, or etching by the use of sputtering; and (8) involving coating by the use of vacuum arc discharge.

Subclass 192.1: Coating, forming or etching by sputtering

Class 118: Coating Apparatus

pparatus for applying or obtaining a surface coating on a base and/or apparatus for impregnating base materials and takes all such apparatus not provided for in other classes. The coating obtained may be permanent or transitory. The coating may be supplied solely by extraneous materials, as in a painting or waxing operation, or may be supplied wholly or in part by the base materials as in the formation of an oxide coating on a metal base. The coating may consist of an emulsion, dispersion, solution, admixture or oil which is clearly disclosed as leaving a residual film, layer or continuous deposit on the base.

Subclass 724: By means to heat or cool
Subclass 726: Crucible or evaporator structure
Subclass 730: Rotary
