Patent DE-4115528-A1 (DE)
Title: Burglar-proof door-lock - uses thrust rod for key bolt operated by electromagnet, key or inner door handle
Inventor: DANILS ERNST
IPC: E05B63/00
Filed: 1991-05-13
Abstract: The door lock has a thrust rod for operating the bolt with a lever. The thrust rod can be moved either by an electromagnet or a toothed wheel attached to an inner door handle. A catch can bear against the toothed wheel to hold it (and therefore the thrust rod) in its end positions. The catch can be activated either through an electromagnet or by rotation of a door handle. A time delay will give 10 to 20 seconds space before the catch is activated. The lock has three operating modes, electrically, mechanically with a key, and from inside using the door handle. The lock system can be modified for remote control of several locks. ADVANTAGE - Electrical or mechanical lock operation recommended by police, suitable for remote control of locks in multi-storey house; improved security against burglars.

Title: Gas generator esp. for airbag in vehicle crash safety system - includes filter chamber, combustion chamber with detonator and propellant for gas generation, etc.
Inventor: REITER RUDOLF
IPC: B60R21/264
Filed: 1991-06-26
Abstract: A gas generator of sheet construction, as part of a vehicle crash safety system, includes a combustion chamber with a detonator and propellant for gas generation, esp. for inflating an airbag with gas leaving a filter chamber connected to the combustion chamber. The novelty is that the gas is divided by a baffle element into a primary stream, which enters a dust collection space, and a secondary stream which escapes via a cooling/expansion space. The combustion chamber (1) is surrounded by an annular space formed of three structural parts (5, 12, 13), which are designed to deflect gas leaving openings in the combustion chamber to form a spiral flow. The structural parts also divide the gas into a primary flow, which is forced into the dust collection space (15), and a cleaned secondary flow which passes through a cooled filter space (14) to the airbag (19). ADVANTAGE - A predetermined pressure/time characteristic for filling the airbag is obtained in a reproducible and simple manner.

Title: Thermostable biological waste water treatment device for tanneries - for aerobic and aerobic treatment in sealed rotating containers for recovering evolved gases and removing solid waste organic impurities
Inventor: SUESSE HARALD DIPL ING
IPC: C02F3/28
Filed: 1991-07-06
Abstract: Treatment is in a system of closed thermostable containers, and the required movement of the biomass in the containers is produced by a rotor.  Biomass is loaded via a chamber directly connected to the rotor.  Emptying rotor, comprising opening chamber by a drive unit which also releases the sealing system.  Reversing the direction of rotation of the rotor conveys the biomass from the rotor into the emptying space and it is removed via an outlet port.  The rotor is mounted in a vessel, and a cushion of air between the outer wall of the rotor and the inner wall of this vessel is used for heat transfer. The vessel is insulated.  The air supply for microbiological bacteria in the aerobic section of the device is provided by pipes on the inner surface of the rotor, and fresh air is supplied via a valve.  These pipes have air nozzles and ends are closed by conical caps to deliver air into the liq. as they pass in and out of the liq.  surface. USE/ADVANTAGE - Esp. used for waste water from leather prodn.  from agriculture and from communal waste disposal systems.  Separate processes for the removal of residual solids are not necessary, and the pollution of the atmos. by the gases e.g.  sulphur dioxide evolved from open treatment tanks is avoided.  The gases and solid materials recovered are used e.g. as fuels.

Patent DE-4135958-A1 (DE)
IPC: G01N21/956
Filed: 1991-10-31
Abstract: A process for detecting impurities on wafer masks uses a focussed laser beam (11) having a reduced numeric aperture for scanning the wafer mask (14). The geometrical distribution of the diffused light intensity in the space surrounding the scanning laser beam is determined by n detectors (17 to 24). Whereas the diffused light emanating from structures on the wafer mask may be described by cylindrical waves, the diffused light emanating from impurities expands as spherical waves. An irregular intensity distribution results, so that only a determined number of selected detectors generate a signal. From the number and position of the signal-generating detectors, the geometric distribution of the diffused light, therefore its origin, may be deduced.

Patent DE-4203335-A1 (DE)
Inventor: LANG ARMIN
IPC: B62D5/08
Filed: 1992-02-06
Abstract: In a power-assisted rack and pinion steering gear, intended especially for motor vehicles, a pinion (2) in a steering box (1) is in engagement with a rack (6). A servo-motor (11) is coupled to the rack (6) to provide power assistance. The pinion (2) is fitted so as to pivot in a fixed bearing (3) and a loose bearing (4). In the region of the loose bearing (4) there are two control valves (26, 27), the axes of which are substantially perpendicular to that of the pinion (2). The loose bearing (4) is guided so as to move perpendicularly to its axis in the steering box (1) only in the direction of the axes of the two control valves (26, 27). In this power-assisted rack and pinion steering gear, the forces used to actuate the control valves are not the axial forces acting on the pinion (2) but the transverse forces. Thus the actuation of the control valves is independent of the helix angle of the pinion teeth.

Abstract: A continuous process, using simple apparatus, for the production of foam beads, in which the blowing agent can be readily recirculated, is characterised in that polymer particles and dispersants are fed continuously to a slender, pressure-operated, non-stirred mass transfer column and in the latter are subjected to a heat treatment under pressure, after which the dispersion is sprayed into a low-pressure chamber and in the process is decompressed, the polymer particles expanding. In the process, foam beads are produced with constant quality without complicated process measures and have in particular a homogeneous cell diameter and a uniform degree of expansion. <IMAGE>
