Abstract: A method and apparatus for quick, safe, and easy installation of electrical fixtures in the building construction field, including connecting the fixture to a mounting mechanism for structural support and electrical service. A coupling mechanism is attached to or incorporated into the fixture. The coupling mechanism has built-in electrical leads that are designed to connect with the electrical leads on a fixture-facing interface of the mounting mechanism. Electrical leads on the coupling mechanism are connected via wire or other electrically conductive material to the electrical components in the fixture.

Abstract: Water treatment systems or assemblies are normally tested after construction, at least for leaks, prior to shipping or storage. Pressure testing with a gas is hazardous, so testing with water is a standard method. After testing, the water is displaced from the system by draining or gas phase flushing. It is nearly impossible to remove all of the water from the system or assembly. This remaining water provides an environment for biological growth which contaminates the system or assembly over time. The purpose of this invention is to eliminate or minimize this biological contamination by adding a biocidal agent to the system or assembly before sealing it for shipment or storage.

Abstract: A universal T.V. channel knob has a channel indicator skirt slidably receivable on a cylindrical, molded synthetic plastic knob shaft and relatively attachable thereto in an infinite number of rotative positions to provide for universal replacement usage. A metal, radially depressable slide pin is provided for securing the dial skirt in adjusted rotative position with respect to the knob shank with only minimal projection inwardly along its mounting shank, thereby minimizing any possibility of interference with fine tuner knob assemblies and the like that may be coaxially arranged in close proximity behind the T.V. channel knob assembly.
