Tubular members of definite or indefinite length including wall structure of the tubular members. Fluid pressure compensators, flow regulators, or baffles not restricted by structure to use with any particular art. Devices for thawing frozen fluid in pipes, for preventing the fluid in the pipes from freezing and for preventing the pipe from bursting if frozen. Pipes with closures and plugs where tied with the structure of the pipe or limited by structure to use with a pipe. Methods and apparatus for repairing pipes where not elsewhere classifiable.

Subclass 38: Heat transfer

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.
