STATEMENT OF GENERAL SUBJECT MATTER OF CLASS
This is the residual class for:
A. Systems or devices which provide safety and protection for other systems and devices.
B. Control circuits for electromagnetic devices.
C. Control circuits for nonelectromagnetic-type relays.
D. Systems or devices which discharge, or prevent the accumulation of electrical charge on or in an object or material.
E. Circuits for charging objects or materials.
F. Systems for generating or conducting an electric charge.
G. Systems which process electrical speed signals.
H. Circuits for reversing the polarity of an electric circuit.
I. Systems which cause the ignition of a fuel or an explosive charge.
J. Systems and processes for demagnetizing a magnetic field.
K. Transformers and inductors with integral switch, capacitor or lock.
L. Electrostatic capacitors, per se.
M. Housings and mounting assemblies with plural diverse electrical components.
N. Electrolytic systems and devices.
O. Miscellaneous electrical systems and devices, which are not generic to any other class and are not provided for in any other subclass of this class.
Lines with other classes and within this class
Many other electrical and mechanical classes provide for systems or machines which include the electrical systems and devices provided for in this class (361). The combination of the subject matter of this class (361) and an art environment is generally classified with the art environment where that environment is significant, either by virtue of a significant disclosed relationship or by virtue of a claimed relationship. Where the art environment is recited by name only (e.g., motor protective circuit), the combination may be classified, in some instances, with the art environment, and in others, in this class (361).
Whereas housings for electronic devices and components are also provided for elsewhere, Class 361 provides for housings and mounting assemblies having more than one different type of electrical component, the electrical components normally do not recite significant art limitations. (See Subclass References to the Current Class and References to Other Classes, below.)
Housings wherein (1) the housing is for an active solid state device, details of which are positively recited in the claims, or (2) where the recited housing is necessary to make a usable active solid state device whether or not the active solid state device is recited nominally or in detail are provided for elsewhere. (See References to Other Classes, below.)
However, if a housing with nominally recited active solid state devices recites different types of (active or passive) devices, then original (OR) classification is in Class 361.
Claims that recite housings with only nominal recitation of active solid state devices of only one type should be classified as originals (ORs) in neither Class 257 or Class 361, but rather in Class 174.
