Abstract: A casing for a laser spark plug, in particular, of an internal combustion engine of a motor vehicle, or of a stationary engine; the casing including at least one casing part and a combustion chamber window joined to the casing part to form a seal at least regionally; characterized in that at least one sealing element, whose coefficient of thermal expansion at an operating temperature of the laser spark plug is greater than the coefficient of thermal expansion of the casing part at the operating temperature of the laser spark plug, is provided between the casing part and the combustion chamber window.

Abstract: An ignition laser is provided for an internal combustion engine, in which the combustion chamber window is connected to a housing of the ignition laser in a gas-resistant, pressure-resistant, and temperature-resistant manner. Furthermore, a pressure relief bore is present which effectively prevents a pressure increase in the housing of the ignition laser.

Abstract: A guiding and stacking system, is provided particularly for guiding and stacking sheet metal parts which are supplied by a press system. The system has a distributing guide which branches the parts flow to two or more guiding and stacking belts. In their entirety or in parts, the guiding and stacking belts operate in the start/stop operation and thus permit the transfer to mechanical gripper devices or manual removal of the sheet metal parts.

Abstract: An apparatus for time dependent control of a regeneration time of an air-dryer. The control apparatus has a shutoff valve, which is disposed in a line between a tank that furnishes regeneration air and an air dryer that can be regenerated by the countercurrent method. For the regeneration of the air dryer, the shutoff valve is switched into an open position by a control pressure and is returned to its closing position by spring force counter to a pneumatic delay device which concludes the regeneration. In the pneumatic delay device, air is displaced through a throttle restriction in the form of a permeable membrane, for instance of porous polytetrafluoroethylene. The apparatus for time-dependent control of the regeneration time of an air dryer is intended in particular for compressed air systems of motor vehicles.

Abstract: A press is provided with gripping rails for moving workpieces in work stations. The press is provided with a motor and a shaft moved thereby, on which shaft cams are mounted. Swing levers follow the shape of the cams, and connecting tabs direct the movements of swing levers toward driving movements of the gripping rails. At least two rollers are rotatably mounted on swing levers. The rollers run on the shaft cams. At least one of the two rollers is pressable with zero play against one of cams by a pretensioning device.

Abstract: An installation for feeding sheet-metal blanks to a first working stage of a multi-stage press, in which the blanks fed individually by way of a suspension conveyor into the area of an intermediate deposit station are to be transferred to active gripping devices attached at the transfer rails. For avoiding standstill periods of the transfer rails during the closing of the active gripping devices, the blank is lifted during the lifting of the transfer rail synchronously therewith. A carriage adapted to be lifted and lowered serves for that purpose which is synchronized by way of a crank drive at least in the lifting phase of the transfer rails with the lifting-lowering drive of the transfer rails.
