Patent DE-3905079-A1 (DE)
Title: Emergency-off switching device
Inventor: WILLEMS HEINZ-JUERGEN
IPC: H01H3/02
Filed: 1989-02-18
Abstract: The invention relates to an emergency-off switch having a mounting flange and an operating plunger which moves with respect thereto in order to produce a switching function, which operating plunger can be pressed from an original position (which represents the switched-on position) against the force of a restoring spring into a switched-off position in which it latches, and can be reset by unlatching rotation into the original position. In order to obtain enhanced safety against incorrect operation, it is provided that the operating plunger is connected to a snap-action element which is prestressed by a spring arrangement into the switched-off position and, in the original position, is latched by a latching device in a latched position, it being possible to stress the spring arrangement into the original position by pulling the operating plunger while it is being reset.
Patent DE-3905422-A1 (DE)
Title: Device for the inductive interrogation and power-feeding of an isolated circuit with electrical load
Inventor: REEB MAX DIPL ING
IPC: G01R31/00
Filed: 1989-02-22
Abstract: This device uses two isolating transformers with a sense winding. When a small alternating test current is fed in, the device simultaneously compares the resistance of the said load with that of a simulation. For this purpose, the device has two outputs, at which direct test voltages which deviate in opposite directions in accordance with deviations of resistance of load and reference element can be picked up. Tolerances of the transformers are compensated for by bidirectional crossed-over transmission of test power and test signal for load and simulation. When an increased alternating current is fed in, the device also effectively supplies the load and limits the power dissipation on the simulation. The device which can be incorporated in CAN/VAN, tests and supplies, for example, the triggering circuit of a safety device, for example a passenger protection device in the steering wheel of a motor vehicle, inductively supplies a steering wheel computer with power and wirelessly transmits, commands, for example for actuating signal means.
Patent DE-3905476-A1 (DE)
Title: Rotary-shackle rope brake for mountaineers
Inventor: LEHNER MARKUS
IPC: A62B35/04
Filed: 1989-02-22
Abstract: Lead climbers have to rely on a rope partner who operates a rope brake. Rope brakes usually have to be guided by human hand, whereby the braking of a fall depends on human performance. This considerable disadvantage is to be removed by the rotary-shackle rope brake, which does not depend on human physical effort. The fully automatic rope-locking mechanism is made possible in the rotary-shackle rope brake by a system controlled by the rope running speed. In this system, a rotary roller (4) with a catch shackle (6) oscillating with it and dependent upon centrifugal force rotates on the rope, in the course of which the catch shackle extended by the centrifugal force at an appropriate rope running speed catches (10) on a transverse beam which in turn is in the rotatable brake piston (11) so that the latter is made to rotate by the rolling movement of the catch shackle and the rope is jammed in the gap between brake block and brake nodule (13), which results in the brake piston being dragged along on the tackle line, in the course of which the brake piston comes into an effective end braking position in which the complementary wave profiles of the brake blocks (21) face one another. Brake-force regulating system: the gap width can be varied (14) by means of adjusting screws. The rotary-shackle rope brake permits fully automatic rope locking. <IMAGE>

Title: Method of removing solvent components from the outgoing air of enamelling installations and the like
IPC: B05B16/60
Filed: 1989-03-08
Abstract: In order to provide a method for removing solvent components from the outgoing air of enamelling installations, with the aid of which the permitted limit values of solvent components in the outgoing air can be observed, it is proposed that the outgoing air is sucked off from the enamelling installation and heat is extracted from the outgoing air until the dew point limit is reached, that the cooled outgoing air is then cooled to below the dew point and the water and solvent contained in the air is precipitated, that the precipitated components are separated and collected, that the cooled outgoing air is heated again by means of the heat extracted in the first step of the method and that the heated outgoing air is introduced into the enamelling installation as fresh air. <IMAGE>
Patent DE-3908016-A1 (DE)
Title: Corkscrew
Inventor: NERN FRIEDEL
IPC: B67B7/04
Filed: 1989-03-11
Abstract: The corkscrew is composed of the body (1), of the securing means (2), of two small corkscrews (3, 4), of a winged handle (9), of a threaded spindle (10) and of a plastic insert (11) for the bottle neck. Corkscrews (3, 4) are composed of a spiral shaft (5), of an attachment piece (6) for guidance and of a thread (7) of the head piece (22). The stop (8) prevents the corkscrews (3, 4) from being screwed in too far. The threaded spindle (10) can be screwed up or down by means of the winged handle (9). The plastic insert (11) is retained by the groove (12). By virtue of the arrangement of the corkscrews (3, 4), a relatively loose cork (14) cannot be pressed into the bottle. The safety screw (18) prevents the winged handle (9) from being unscrewed. The thread (19) for the threaded spindle (10) serves for fastening the securing means (2). They thus form a fixed unit. The corkscrews (3, 4) fit accurately through the bores (20, 21) of the securing means (2) and can be screwed into the cork (14) as far as the stop (8). The two headpieces (22) with thread (23) can be screwed on. The legs (16, 17) fit into the milled reliefs (24, 25) of the securing means (2), rotation of the securing means (2) is not possible. The bore (26) serves for guiding the threaded spindle (10). <IMAGE>

Title: Removal of coke dust from circulating gas in coke dry cooling plant - with return of gas to coke shaft after extraction of waste heat and dust
Inventor: STALHERM DIETER DR
IPC: C10B39/02
Filed: 1989-06-29
Abstract: This is a method, with the associated plant, for removing coke dust from the circulating gas of a coke dry-cooling plant having gas cooling and surface cooling. The gas, containing the dust, leaves a coke cooling shaft, turns (pref. about 90 deg.) into a gas duct, and after extraction of waste heat and dust is returned to the coke shaft. By turning into the gas duct and being led along near the duct inner wall, the coke dust is cleaned off and is removed from the duct. A variant is claimed for the cleaned-off dust to be sucked out and led to the dust collector, and several variants are claimed for the dry-cooling plant. USE/ADVANTAGE - This is a simple and improved method for removing the coke dust fromm a dry-cooling plant, and in particular provides a simple means of removing coarse dust before the extraction of waste heat.
