Abstract: In a hand held heated dispensing device contact of an operator's hand with sensors 8 carried by hand-grip 2 serves to switch the device from a low temperature setting to a high temperature setting for a melting chamber (not visible) to which solid adhesive 5 is fed by operation of trigger 4 to dispense molten adhesive from nozzle 6. When the device is put down (e.g. for positioning a component to be adhered in place) removal of the operator's hand from contact with the sensors 8 causes switching back, if desired after a short time delay, to the low temperature setting. This arrangement reduces the time necessary for the device to be brought up to temperature each time it is required to be used. <IMAGE>

Abstract: An explosive powder operated setting device uses the propellant gases from an ignited explosive powder charge for driving a piston which, in turn, propels a fastening element from the device into a receiving material. The device includes a housing, a barrel mounted in the housing with the piston displaceably mounted in the barrel. A tubular-shaped slide valve is rotatably mounted in the rear portion of the barrel behind the piston. The front end of the slide valve combines with the barrel in forming a space in which the propellant gases contact the piston and drive it through the barrel. The rear end of the slide valve forms a part of the combustion chamber within the device. At its front end, the slide valve is frusto-conically shaped and forms a seal with a correspondingly shaped surface in the barrel. An exhaust duct section extends through the barrel and is in communication with another exhaust duct section in the housing. The slide valve has exhaust openings extending radially through it which can be aligned with the exhaust duct section in the barrel so that, if required, a part of the propellant gases can be exhausted to the atmosphere without being used for driving the piston.

Abstract: Dual circuit brake force control units are known in which the initial preloading force is changeable dependent on the vehicle load. The preloading force is distributed to the control pistons by means of a lever. Due to the tolerances and erosion of the individual elements, considerable differences in pressure in both brake circuits may occur. Therefore, according to the present invention a lever is provided which directly acts on both control pistons and which is rotatable around an axis parallel to the direction of displacement of the control pistons and additionally around the longitudinal axis of the lever. The lever is in interaction with its housing mount at one support point at least and at two support points at the most with the support point or support points being located at least approximately in the longitudinal axis of the lever.

Abstract: For the control of a brake-slip controlled brake system the brake pedal force assisted by auxiliary force is transmitted onto a master cylinder (10, 10', 33) and from said onto the wheel brake cylinders via several pressure fluid paths that are adapted to be closed independently of one another. The wheel rotational behavior and the vehicle velocity will be measured with sensors (S1 through S4), the signals will be logically combined, and therefrom control signals will be generated for electromagnetically actuatable directional control valves (15, 16, 17, 19, 35, 36, 37, 42, 43, 52). During control action, the pedal force (F) that is directed to the master cylinder and assisted by auxiliary force will be compensated temporarily by an opposed force, as a result whereof the pressure rise in the master cylinder will be retarded or pressure will even be decreased. During the phase of reduced pressure in the master cylinder, the switching position of the directional control valve (15, 16, 17, 35, 36, 42, 43) which are inserted in the pressure fluid lines (24, 24', 25, 25') leading to the wheel brake cylinders will arrange for the pressure in the wheel brake cylinders to be either maintained constant due to line closure, or to be reduced to the level desired by causing pressure fluid to discharge to the master cylinder (10, 10', 33) through the directional control valves switched to open passage.
