Abstract: A sensor device, comprising a pyroelectric sensor which is set to operate in daylight, especially an infrared-based motion sensor, and an electronic evaluator. The electronic evaluator is connected downstream of the sensor and is configured to produce a control signal in response to a detector signal from the sensor in relation to a threshold value. The electronic evaluator also has a sensing device for measuring a daylight ambient brightness and a compensating device which is configured to respond to a considerable change in the daylight ambient brightness by modifying the threshold value and/or the detector signal to compensate.

Abstract: An adhesive cartridge which is adapted to receive adhesive which is liquid or which is to be liquefied under the influence of heat and is usually used together with a hot-melt applicator device which provides for a suitable supply of heat.

Abstract: The invention relates to a hot-melt adhesive applicator having a manually handleable applicator unit which is adapted to electrically heat a replaceably insertable adhesive container, in particular for adhesive which can be liquefied by the action of heat, and which has a heating unit of a material of a predetermined heat capacity and which is provided for transferring heat to the adhesive container and which affords a contact surface for the heat transfer and which has an electrical heating element, and a support module which is adapted to act on the heating element with an electrical voltage in a fitted holding condition of the applicator unit, the support module being so designed that the heating element is supplied with voltage only in the holding condition and the supply of voltage to the heating element cannot occur when the applicator unit is in an adhesive application condition of being detached from the support module.

Abstract: A halogen motion detection security light positioning system comprising a base, a yoke and a housing. The yoke having a crossbar and a pair of opposed facing prongs that extend from opposite ends of the crossbar. The yoke being rotatably connected at the crossbar to the base by a frictional securing mechanism. The housing has a halogen receptacle and is rotatably connected between the opposed facing prongs of the yoke by a self-locking securing mechanism that prevents rotation in an unflexed state and allows rotation in a flexed state.

Abstract: An electric device for evaporating substances, such as perfumes or the like, including a housing which is adapted to have inserted therein a receptacle containing the substance in question. The device has an electric circuit supported in the housing and formed of two circuit components which are placed one on top of the other and between which a PTC element is arranged. Each of the circuit components is formed of an injection molded part and a stamped sheet metal component embedded therein. The circuit components are coupled to one another mechanically and electrically by an integrally formed stamped sheet metal component and one circuit component is folded onto the other when the device is being assembled.

Abstract: An electric device for evaporating substances, comprising a housing, a printed circuit board supported in said housing and used for an electric heating element, and a toggle switch including an operating element which is adapted to be pivoted by a defined angle. The toggle switch is provided with an integral strip-shaped sheet-metal spring serving simultaneously as a switching element for interrupting and for establishing an electrically conductive connection between two contacts and as a resilient element holding the switching element at two stable switching positions. The strip-shaped sheet-metal spring has two end pieces, one end piece being coupled to the operating element and the other end piece abutting directly on one of the two contacts. Furthermore, the strip-shaped sheet-metal spring includes a 3/4-circular bend which is brought into contact with the other contact by pivoting the operating element.

Abstract: A self-locking adjustable light fixture comprising an arm, a base, a hood, an arm securing mechanism, and a hood securing mechanism. The arm has an annular shape with interconnecting protrusions at a proximal end and a distal end. The base has mating interconnecting notches that are axially aligned with the interconnecting protrusions of the proximal end of the arm. The base is connected to the proximal end of the arm by the arm securing mechanism which biases the interconnecting protrusions at the proximal end of the arm with the mating interconnecting notches of the base to prevent rotation of the arm. The hood has mating interconnecting notches aligned with the interconnecting protrusions at the distal end of the arm. The hood is connected to the distal end of the arm by the hood securing mechanism which biases the interconnecting protrusions at the distal end of the arm into the mating interconnecting notches of the hood to prevent rotation of the hood with respect to the arm.

Abstract: An electric device for vaporization of additives having a housing with an electric heating disposed therein. The heating includes a heating element and a heat exchanger, to supply the heat generated by the heating element to the heat exchanger and to convey it to the substance to be vaporized. The heating element is a PTC element, clamped between two electrodes and at least one of the two electrodes is disposed in proximity to the heat exchanger and is integrally formed with it.

Abstract: An electric device for the vaporization of additives has a housing in which an electric heating unit is disposed and into which the additive is to be inserted. The device has a heat exchanger, which is in heat connection with the heating unit and which is disposed at a location to vaporize the additive. The device includes a plug for a wall socket which is rotatable relative to the housing and has a rotating joint carrying a set of contacts. A set of counter-contacts is at the housing and arranged in a manner to produce an electric connection in two positions of the plug offset from the housing by about 90.degree., and an annular range in between having a switching position in which the connection is opened.

Abstract: The present invention refers to a device for melting and dispensing metered amounts of thermoplastic adhesive, having a heatable melting chamber, having a connecting sleeve formed at the entry side of the melting chamber, and a sealing collar, having a through opening in the axial direction, through which the adhesive can be inserted into the melting chamber. The sealing collar is composed of two pieces, a heat-proof first part and a resilient second part, wherein the resilient part is enclosed by a first part in an overlapping region and the first part is mounted onto the connecting sleeve.
