Abstract: A tubular member 12 having an internal and/or external metal thread 18, 20 at one end thereof, at least part of the thread 18, 20 being coated with an alloy of copper and tin, said alloy containing 5 wt % to 95 wt % copper. The tubular member 10 can be combined with another tubular member 14, 16 to provide a threaded connection 10 having improved galling resistance.

Abstract: A method for grounding a plurality of snap switches arranged in a wiring box to a common ground source includes: connecting together in series the equipment grounding terminal of each snap switch with sheathed connecting wires such that each equipment grounding terminal of each snap switch is disposed in electrical communication only with the equipment grounding terminal of each other snap switch, the electrical communication forming an electrical network; and, connecting with a sheathed lead grounding wire the electrical network to a common ground source of the wiring box such that each snap switch is grounded. An electrical switch apparatus of the present invention includes a wiring box and plurality of snap switches mounted to the wiring box. Each snap switch includes an equipment grounding terminal. The electrical switch apparatus also includes a plurality of sheathed connecting wires.

Abstract: An electrical conduit fixture for directing wire within the conduit through a directional change includes a body having walls defining an inlet and an outlet with the outlet being oriented 90.degree. from the inlet, the body being formed in at least two matable sections with a portion of the inlet being formed in a first body section and a portion of the inlet being formed in the second body section and an arrangement for removably fastening the body sections in a mated relationship.

Abstract: The invention is directed to a portable data logging device for logging d concerning room identification and dimensions in a building or facility. The invention includes a microprocessor based portable computer having manual and automated inputs for logging data including a data port for room dimensions. An electronic distance measuring device produces an output indicative of one or more room dimensions in a digital format. An auxiliary processor responsibly coupled to the output of the distance measuring device converts the output to a coded format recognizable by the microprocessor. The data encoded in the coded format is coupled to the microprocessor via a voltage converter for recordation. The microprocessor may be programmed to step through a series of prompts, responses to which are stored in appropriate data locations for use at a later time.
