Systems or devices which discharge, or prevent the accumulation of electrical charge on or in an object or material; circuits for charging objects or materials. Systems for generating or conducting an electric charge. Systems which process electrical speed signals. Circuits for reversing the polarity of an electric circuit. Systems which cause the ignition of a fuel or an explosive charge. Systems and processes for demagnetizing a magnetic field. Transformers and inductors with integral switch, capacitor or lock.

Class 174: Electricity: Conductors And Insulators

This class is for inventions relating to the structure of electrical conductors and insulators and insulators and the apparatus specialized to mounting, supporting, encasing in conduits, and/or housing the same. Conductors may be bare or be encased in insulation, may be single strand or plural strand, may be of single conductor form or there may be a plurality of conductors associated together to form a cable. Since all materials that have the property of being conductors of electricity and all devices made therefrom may be termed electrical conductors, only those structures that are specially designed to conduct electricity as their proximate purpose are placed in this class. Insulators are placed here when the structure thereof is claimed, which structure is specially designed for spacing two or more devices of different electrical potential from each other or for spacing one or more devices from ground. Since all materials which are poor conductors of electricity and devices made therefrom may be termed electrical insulators, only those structures whose proximate purpose is that already stated. Conduits are placed in this class only when some characteristic is claimed which limits the same to the electrical use.
