Abstract: A lighting system for clothing, footwear, backpacks, and other accessories incorporates a battery, a switch, a counter circuit, a flasher and lamps or LEDs driven by the flasher. An improved switch has a tubular housing of electrical insulating material, which may be, for example, round or square in cross section. A pair of electrical contact pins extend into the interior of the housing and are aligned longitudinally. The external ends of the contact pins are wired to the counter circuit and the battery. A free-floating contact bar of electrical conducting material normally resides on the bottom of the housing and, upon movement of the shoe or clothing, will bounce against the contact pins thus closing the switch and causing an input signal to the counter circuit and causing the lamps or LEDs to be illuminated momentarily. In a second embodiment, the contact pins extend through the bottom of the housing and the contact bar may rest against the contact pins.

Abstract: A piping system for adding fuel to underground storage tanks includes a fill piping system and a vapor return piping system designed to prevent fuel spills and leakage of fuel vapors into the atmosphere. Fuel and vapor leakage are avoided by eliminating most of the threaded joints in each such piping assemblies by welding them into joint-free unitary stainless steel assemblies. A brace bar extends between the fill and vapor return piping systems and is secured to octagonal side flats on both assemblies such that the octagonal members cannot rotate unless the brace bar is removed. Annular synthetic rubber spill buckets are selectively inserted into each piping system to catch spills and prevent fuel from leaking near the tank or vapor from leaking out of the vapor recovery system into the atmosphere. In another modification, the spill bucket is used only on the fill piping system.
Abstract: A holster for carrying a handgun having a movable welt which reduces the likelihood that the handgun will be the subject of either an accidental or intentional dislodgment. The movable welt rotates about 10° to 15°, and as it rotates, the handgun is moved from a position where its hammer region is secured by a fixed strap and the weapon may not be removed to a position where the strap is no longer an issue and the weapon may be removed.
Abstract: A metal halide light fixture includes three generally cylindrical parts including a lamp housing with a lamp and a lamp socket, an intermediate sleeve member secured to the lamp housing, and a third focusing housing secured to the intermediate sleeve member. The focusing housing includes a reflector member including a concave reflecting surface and a lens. The lamp housing carries a T-6 lamp or similar lamp which includes a cylindrical arc tube having a significant axial length. Rotating the focusing housing moves the reflector member which surrounds the lamp axially relative to the arc tube to shift the light output pattern from floodlight to spotlight. The lamp housing is connected to a mounting structure through a swivel connection. Wires from the lamp socket are fed through a port in the lamp housing and a channel in the mounting structure and are potted in place. Threaded connections between the three principal parts are protected by O-ring seals.
