Title: Electrical central-locking device for a plurality of locks of a vehicle, especially of a motor vehicle
Inventor: WITTWER REINHARD
IPC: E05B77/48
Filed: 1983-09-21
Abstract: In an electrical central-locking device for a plurality of locks arranged at various points on a vehicle, these can be brought into three positions, namely a desecuring position, in which interior and exterior handles can be actuated, a normal securing position, in which this is not possible, and a special securing position, in which the interior and exterior securing handles are also blocked. Actuating drives are used for the central locking and act on the locks. For a simple and universally lockable device, it is recommended to obtain normal securing by means of a mechanical key, but to bring about special securing by interaction between an electronically coded transmitter and receiver, the receiver being connected electrically to each actuating drive.

Title: Safety hairdryer
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H02H5/08
Filed: 1983-11-02
Abstract: The invention proceeds from an earth leakage current protection device in which a short-circuit circuit breaker is installed in the electrical load apparatus or in the supply lead, which circuit breaker short-circuits the supply lead in the event of a fault and in this way causes the upstream-connected fuse to cut off. In order to be largely independent of the respectively provided system fuse and of the respectively provided network internal impedance, and additionally in order to achieve a shorter cut-off time, that is to say significantly to increase the electrical safety, a relatively low-current fuse is installed in the load apparatus or in the supply lead, in each conductor, and the short-circuiting switch is dimensioned independently of the fault time phase with respect to its switching-on time phase, such that a short-circuit current is ensured which is sufficiently high to cut off all the fuses.

Title: Process for manufacturing gas diffusion electrode bodies
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: H01M4/88
Filed: 1984-10-12
Abstract: In manufacturing porous gas diffusion electrodes it is possible to avoid destruction of the electrode structure due to the necessary repressing after removal of a filler material which had been incorporated in the electrode substance, if the filler comprises at least two components which can be removed separately, e.g. on the basis of different decomposition temperatures or solubilities. The compaction after removal of the first component (e.g. readily sublimable ammonium bicarbonate), but with the second component (e.g. citric acid soluble in hot water) still present then results in a stable and readily conductive electrode framework.

Patent DE-3440901-A1 (DE)
Title: Arrangement for finely atomising fluids
Inventor: HERZOG HANS-JOACHIM
IPC: B05B1/26
Filed: 1984-11-09
Abstract: The arrangement for finely atomising fluids is preferably used for atomising water in extinguishing systems inside complexes of rooms such as cooking shelf stores, or for surface fires. The extremely fine atomisation produces an extinguishing method with the highest possible extinguishing intensity, in which the known water damage to buildings and to stock is largely avoided. In dust fires, the novel nozzle arrangement is intended to prevent dust explosions. Inside a spray head, a multiplicity of twisting bodies are positioned in an angular fashion to one another, as a result of which their individual emerging spray cones in the region of their cone envelope cause water microparticles to be formed in the entire distributor zone as a result of mutual penetration and splitting up of the water droplets. The cone envelope can be of convex construction for spatially limited areas and of concave construction for spatially unlimited areas. <IMAGE>
