Abstract:
The present invention teaches a lockable lampholder mounting system wherein a housing containing electrical contacts, such as an electrical wiring device of the type exemplified by an incandescent lampholder or socket, is removably mounted upon a preselected panel by means of a novel clip arrangement. The panel is of the type utilized in a fixture, for example. The clip arrangement includes a resilient clip of predetermined shape formed with at least three bearing surfaces for contacting the panel, and preferably a fourth bearing surface against which a locking tab is biased to prevent rotation and relatively upward movement of the wiring device.
Heat Flow Detector For Recessed Incandescent Fixtures

Leviton Manufacturing Co., Inc. - Little Neck NY
International Classification:
H02H 504
US Classification:
361103
Abstract:
A heat flow detector is described which measures a predetermined rate of heat flow in its surroundings. The surroundings being in the proximity of a recessed incandescent fixture which is designed to operate safely in the designated environment. Should the operating environment change for the fixture it will be sensed by the heat flow detector. If the operating environment becomes more dangerous so that a fire or other damage may occur the heat flow sensor will turn the incandescent lamp off and on at a slow rate to indicate the changed operating environment. The heat flow detector will cause a slow turn off and on if an oversize lamp is inserted in the incandescent fixture. The heat flow detector will then prevent an overheated condition due to an incorrect bulb.

Abstract:
An electric series circuit with plural loads such as light bulbs connected in series and plural solid state switching devices, with each switching device connected in parallel with one of the loads. Each switching device conducts current when the load that it is connected in parallel with does not conduct current because the load is burned out. The solid state switching means may be any device with a breakthrough voltage which is high enough that it does not conduct when all of the loads conduct current normally. When one of the loads is burned out, that load does not conduct current and the entire line voltage appears across the switching means in parallel with the burned out load. The switching means breaks down. Accordingly, the switching means conducts current and current flows to the remaining loads.
A wire connector. A body member has a lower hollow internally threaded portion and an upper portion with a slot in the lower portion. A pair of spaced electrodes are mounted in the upper portion, the lower ends of said electrodes being pointed and extending into the area of the slot. A ring member has a central portion bridging the ring, and the ring member is slidably mounted on the lower portion of the body member. An externally threaded member is threadedly connected to the internally threaded hollow portion of said body member. Whereby an insulated two conductor cable may be inserted through said slot between the lower ends of the electrodes and the ring member and the externally threaded member may be screwed into the body member to force the electrode points through the insulation of the cable and causing each electrode point into contact with one of the conductors of said cable.
