Class 29: Metal Working

Metal working or shaping - it comprises processes, tools, machines, and apparatus not classifiable in the specific classes relating to the manufacture of articles from metal. It has been made the generic class for the following regardless of the composition of the blank, stock material, or article recited or worked upon: (a) process of electric condenser making; (b) a burnishing process; (c) a process of manufacture; (d) apparatus used to assemble or disassemble.

Subclass 25.35: PIEZOELECTRIC DEVICE MAKING
Subclass 25.42: Solid dielectric type
Subclass 612: Thermally variable
Subclass 620: Coating resistive material on a base
Subclass 621: Applying terminal
Subclass 621.1: Strain gauge making

Class 439: Electrical Connectors

This is the generic class for a pair of mated conductors comprising at least two electrically conducting elements which are interconnected to permit relative motion of such conducting elements during use without a break in electrical conductivity therebetween. Also, this is the generic class for a device constituting an electricity conducting contact between conductors of electricity; wherein the joint is of a type which may be readily made and broken, repeatedly by attachment and detachment of contact supporting structure on each conductor.

Subclass 638: Two or more plural-contact coupling parts combined in one integral unit
Subclass 686: Having multipart insulating body or casing

Class 338: Electrical Resistors

Electrical resistors with solid, granular, or liquid resistance elements. These resistors may be either fixed or variable in resistance value. Semiconductors are included if limited by claimed subject matter to resistance properties, such as exists in photoconductive and thermistor type resistors. Included also are resistors with perfecting structure such as resistors whose resistance value is temperature compensated, or mounted on wheels or on a vehicle, resistors with heat dissipating projections, or with cooling gas or liquid circulation, or with heat storing, or with inductance or capacity reducing, or with electrical shields, or with a cleaner or a setting indicator in a mechanically variable resistor, or with a casing or housing, or with protecting structure spaced from the element, or with mounting or supporting means. Included also are resistors combined with or incorporated in other structure, as are resistors constructed as by shape or from material to change their resistance value particularly well in response to a particular condition or change in a particular condition such as current and/or voltage. Included are resistors usually of the mechanically variable type together with a condition sensing actuator which changes the mechanical adjustment of the resistor in response to a condition or a change in condition.

Subclass 42: Diaphragm

Class 374: Thermal Measuring And Testing

(1) a characteristic or condition of an object or system utilizing heating or cooling as a significant part of the test and not provided for in other classes, or (2) a thermal quantity or condition. This class also includes circuitry and devices with structure unique to a thermal measurement or test.


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 100: Piezoelectric properties
