Abstract: An electrical apparatus housing assembly unit is constructed from mounting columns, a top and bottom panel member and two side panel members. The mounting columns serve as structural components of the electrical housing assembly unit and also as members to which electrical components and the like may be removably mounted. Additional component parts such as facias and spacers may also be mounted to the mounting columns. The facias and spacers, in addition to aesthetic value, provide additional strength to the electrical apparatus housing assembly.

Abstract: A recessed handle assembly adapted for use in cases, panels and more particularly in electrical housing assembly units is disclosed. An aperture is provided in a wall of an electrical housing assembly unit. Into the aperture is placed a handle member which is preferably U shaped and is equipped with a pair of flanges. The flanges engage the exterior surface of the panel. A keeper member which also has a pair of flanges is mounted between the panel and the handle member. The keeper member is of such dimensions that it tightly fits between the panel and the handle member while the flanges of the keeper member engage the interior surface of the panel. The whole assembly is held together by a spring force which results from tight fit of the keeper member between the panel and the handle member. The handle assembly of this invention can be mounted into a panel in a very short time without the use of tools or mechanical skills.

Abstract: A machine for removing cemented carpets, tiles and like coverings from a floor or other surface. A cam is mounted on the shaft of a drive motor secured to a frame of the machine. A blade-carrying bracket is pivotably mounted on the frame, and a follower block is rigidly secured to the bracket. The follower block has an oblong opening to receive the cam, and to translate rotary motion of the cam into reciprocating motion of the blade.

Abstract: A disposable electrosurgical unit for generating electrical signals intended for applications to the body of a patient via an electrosurgical electrode is provided. Cutting signals and coagulation signals can be applied by the actuation of a switch in the handle supporting a removable blade electrode. The electrode blade has a mounting end configuration that can be removably mounted in a receptacle portion of a resilient conductive member. The conductive member is biased by its particular bowed shape and mounting configuration away from wire wrap contacts connected to a power generator source. The switching member is mounted in the electrode handle for selectively moving one of the bowed portions of the resilient conductive member into contact with a wire wrap contact for actuation of the electrode blade in a desired operative mode.
