A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.

Subclass 141: Continuous and nonuniform or irregular surface on layer or component (e.g., roofing, etc.)
Subclass 143: Particulate matter
Subclass 172: Composite web or sheet
Subclass 173: With partial filling of valleys on outer surface

Class 324: Electricity: Measuring And Testing

This is the residual home for all subject matter, not elsewhere classified, relating to the measuring, testing (or sensing) of electric properties, (e.g., determining ground resistivity, determining frequency of an alternating current, determining kilowatt hour demand), or the measuring, testing or sensing of nonelectric properties by electric means (e.g., determining moisture, a nonelectric property, by measuring conductance with a resistance bridge; determining speed, a nonelectric property by use of an electric tachometer).

Subclass 754: With probe elements
Subclass 767: Diode

Class 318: Electricity: Motive Power Systems

This is the generic class for system of electrical supply and/or of control for one or more electric motors where the electric motor is claimed in combination with such systems of supply and/or control and the electric motor as claimed constitutes the ultimate and sole electrical load device supplied by the system or constitutes the ultimate and sole electrical device being controlled.

Subclass 116: NONMAGNETIC MOTOR
