A fastening arrangement comprises a screw (14) to be used as a weld screw for the arrangement of at least one cable terminal (20) with a cable holder (21). The screw (14) has a base portion (15) which is polygonal in cross section with an outer rim (16), and with a plastic part (1) which cooperates with the screw (14) and of which the lower portion (2) has an aperture (3) with an inner rim (4) adapted to the outer rim (16) of the base portion (15) and of which the upper portion (5) has recesses (6a, 6b, 6c, 6d, 6e, 6f) limited by pegs (7a, 7b; 7b, 7c; 7c, 7d; 7d, 7e; 7e, 7f; 7f, 7a) with an orifice (8) for receiving the cable holder (21). At least one peg (7a, 7b, 7c, 7d, 7e, 7f) two adjacent pegs (7a, 7b; 7b, 7c; 7c, 7d; 7d, 7e; 7e, 7f; 7f, 7a) has at least one web (9a, 9b, 9c, 9d, 9e, 9f) which extends to the adjacent peg (7a, 7b, 7c, 7d, 7e, 7f) and partially limits the orifice (8).

Absorbers for rotating shafts, particularly for universal-joint propeller shafts in motor vehicle construction, are formed with a segmented elastomer ring interconnecting an outer inertia ring and an inner hub ring. The inertia ring is connected to the hub ring with two to six connecting links made of elastic material which, in axial cross-section, primarily have the outer contour of a radially aligned and tangentially constricting "X". Surface complementary buffer webs are placed between the connecting links and form a comparatively close equidistant parting gap in relation to the neighboring connecting links and to the opposing surface of the hub ring.

The invention relates to a plug-and-socket connector with a first housing with first electrical contacts and a second housing with second electrical contacts. The first housing has a lever which is rotatably mounted on the first housing, the second housing having a toothed surface on which the lever arm can be brought into contact with an actuating surface upon pivoting, in order to draw the first and the second housing together into an end position in which the first and the second contacts are contacted with each other. The first housing has a blocking element which, in a pre-assembly position of the first and the second housing in which the two housings are partially inserted into one another, blocks pivoting of the lever arm into the end position. The second housing has a release surface, with the release surface displacing the blocking element upon pushing together the two housings from the pre-assembly position into an assembly position, so that the lever arm can be moved from the pre-engagement position into the end position in order to assemble the two housings into the end position.

The present invention relates to an attachment device (100) for the sun visor of a motor vehicle having a receiving housing (106) mounted on the motor vehicle and a sun visor foot (108) connectable with the sun visor, wherein the receiving housing (106) and the sun visor foot (108) each comprise contacts for producing an electrical connection. The electrical contact of the receiving housing (106) has a first contact point (158) and the electrical contact of the sun visor foot (108) has a second contact point (144) whereby the first contact point (158) and the second contact point (144) are in electrical contact with when the sun visor foot (108) is mounted in the receiving housing (106).

The invention relates to a method for short-cycle arc welding with drawn-arc ignition, wherein a stud is welded to a piece of sheet metal, with the following steps: provision of a stud having an end face with which the stud is welded to a welding surface of the sheet metal, wherein an integral distinct projection is formed in the end face, placement of the projection on the welding surface and switch-on of an electric pilot current, lifting of the stud from the welding surface, whereby an arc is drawn, establishment of a welding current flowing through the arc in such a manner that the end face and the welding face start to melt, lowering of the welding stud onto the welding surface, wherein the melts at the end face and welding surface mix, and switch-off of the welding current so that the entire melt solidifies to join the stud to the sheet metal in a material-to-material manner, wherein after lifting of the welding stud and before establishment of the welding current, an alternating cleaning current is initially established in a cleaning step that is designed to clean the welding surface and/or the end face of contaminants, such as lubricants or wax, and/or of coatings, for example corrosion-protective coatings of zinc.

A fastening system is providing, the fastening system has a weld stud welded to a sheet metal surface at a weldment portion to form a weld joint. The system additionally has a fracturable nut coupled to the weld stud. The fracturable nut and stud construction is configured to fail under torsional load prior to the failure of the sheet metal or the weld joint.

An operation testing of a temperature sensor of an alarm includes spraying so that the sprayable material is sprayable on the temperature sensor, a temperature decrease due to the spraying is detected, and an operation ability is determined in dependence on the testing.
摘要:
A fire detector having a sensor group containing at least one fire detection sensor and having a control and evaluation unit, which is connected to a sensor group that is set up to evaluate signals supplied by the at least one fire detection sensor, and if necessary, that is also set up to output at least one control signal for the at least one fire detection sensor. The sensor group includes one of a chemosensor and a chemosensor array, which is connected to the control and evaluation unit for evaluating a detection signal of the one of the chemosensor and the chemosensor array, and which is set up based on a chemical sensor-operation principle to detect gas emissions and/or smoke emissions associated with a fire. The additional chemosensor may be an optoelectronic gas sensor functioning on an optode basis or an optoelectronic gas sensor array functioning on an optode basis.

A device for manometric measurement of the oesophagus has a catheter with a pressure sensor and a recording unit with a light source for monochromatic and coherent light, and a counting unit for light pulses. The pressure sensor is constructed as a Fabry Perot measuring section and has a pliable optical fiber embedded in elastic base material. The optical fiber is connected via a fiber-optic light guide to the recording unit (3). One end (6) of the optical fiber (5) is metal-coated and the other end (7) is partially metal-coated and connected to the fiber-optic light guide (8). The fiber-optic light guide (8) conveys not only the light from the light source to the optical fiber but also the light pulses from the optical fiber to the counting unit.
