Abstract: Disclosed is a tubular housing having a threaded-base lamp bulb at one end and a "penlite" battery within the housing with its positive terminal stud separated from the bulb's positive terminal by a helical compression spring. The spring coils receive the lamp base and the spring is bottomed and centered in an annular retainer disc encircling the positive terminal stud of the battery. A conductive strap engages the endmost coil of the spring and extends the length of the battery to its base providing electrical continuity from the battery negative terminal to the bulbs threaded base. A push button, accessible at the end of the housing, moves the battery so that its positive terminal engages the positive terminal of the bulb.

Abstract: An electric igniter is disclosed which comprises two elements made of electrically conducting material, a body separating the elements and made of electrically insulating material, such as glass or material containing glass, at least one further electrically conducting element arranged on a surface common to the two elements and the body for connecting the two elements electrically, and also a pyrotechnical composition in contact with the surface and the further element. Burning of the composition can be initiated by means of heat developed in the further, initiating element.

Abstract: The invention relates to a case of plastics material for an electrical pocket flashlight or pocket lamp energized by battery. It is composed of two bodies, an inner and an outer, assembled together by clipping, the upper body including the parabolic reflector into which a shouldered socket holder ring is adjusted. The metal socket inserted therein has a base provided with a flexible metal strip. In the lower body, slides a cradle supporting the battery and bringing by vertical translation, under the effect of a push-button, the terminals of the battery into contact with the metal strip and the base of the flashlight bulb.

Abstract: The invention includes a housing having a first hollow portion threadedly engaged with a second housing portion has a translucent section and an internal wall formed with a hole through which a light bulb extends. The light bulb has a collar on the base thereof which engages the internal wall. Formed within the first hollow portion is a hollow cylindrical member in which a battery is positioned with a spring positioned between one end of the portion which urges the other end of the battery to contact the base contact of the bulb. A wire contacts the base of the battery with the base of the light bulb.

Abstract: The illumination device comprises a body, an illumination means, a holding means and a switching means, the last mentioned three means being attached to said body. Said holding means includes a battery and a biasing means made of an electrically conductive material. The holding means is made of an electrically conductive material and is constantly electrically connected to one electrode of said battery through said biasing means. The biasing means is designed to function so as to keep the other electrode of the battery in the state of being constantly electrically connected to one terminal of said illumination means while keeping, in a steady state, the holding means in the state of being removed from the other terminal of the illumination means.

Abstract: In a pocket torch the bulb itself is used as the switch. It tilts between two positions of stable equilibrium, while being confined resiliently between the casing and the battery.

Abstract: A device for heating keys comprised of a plug which fits the socket of a cigarette lighter having means for heating a key. The device is comprised of a heating element surrounding a slot in the plug into which a key may be inserted for heating. The plug, when pushed into the cigarette lighter receptacle, activates the heating element which in turn heats the key. The device can be constructed as a slot in an existing cigarette lighter for use in conjunction with it, or may be a separate adapter plug. The device is activated by pushing the key into the slot in the plug or cigarette lighter and engaging the contacts by pushing the plug inward.

Abstract: A diver's flashlight having a unitary case with a closed transparent end for light transmission, the other end being sealed by a threaded plug which also serves as a switch. A halogen bulb is mounted in a reflector immediately inside the transparent end and a rechargable battery is held normally out of contact with the bulb by a spring. Tightening the threaded plug overcomes the spring and completes the circuit when the plug is fully seated in sealed position. The plug, and a cap fitted over the transparent end, are of luminous material for night use.
