Patent DE-4239464-A1 (DE)
Title: Electrothermal static micro-pump with fluid-pressure-operated valve - drives liq. past resilient flap into outlet by expansion of vapour bubble generated by electric heating element
Inventor: HEINZL JOACHIM PROF DR ING
IPC: F04B53/10
Filed: 1992-11-24
Abstract: The pump has the heating element (2) on the floor of a liq.-filled chamber (4) in a monocrystalline Si structure to generate a bubble (14) of vapour in the space between an inlet constriction (8) and an outlet which is controlled by a flap valve (12). The fluid-mechanical impedance of the valve is less than that of the constriction so that instead of "blowing back" into the inlet (6), the bubble opens the valve before contracting to allow more liq. to enter. ADVANTAGE - Very compact pump, improves action with high capacity and reliability over long period, having no moving parts other than static valve(s).

Patent DE-4306279-A1 (DE)
Title: Device for monitoring exposed films
Inventor: MANEWALD INGRID
IPC: G01N31/22
Filed: 1993-03-01
Abstract: To ensure that films which have been recorded on are reliably monitored in time when a chemical decomposition of the film stock sets in, a colour indicator is used which is in the form of a layer of granules and suddenly changes its colour when it reacts with the gas which has been formed during a decomposition. The layer of granules is arranged inside a housing inserted into a wall recess of the film container. A non-return valve is built into a further wall recess of the film container and ensures in conjunction with one or more venting channels of the housing a forced gas flow, consisting of the external air which has flowed into the film container through the non-return valve and of the decomposition gas which has possibly been produced in the film container, through the layer of granules. By means of a magnification lens integrated into the housing the layer of granules can be imaged on an enlarged scale so that the colour of the layer of granules can either be read more easily by an operator even from a relatively large distance or scanned and evaluated electronically by automatic monitoring. <IMAGE>

Title: Beam=setting regime for motor-vehicle headlamps to reduce glare - aligns offside beam away from oncoming traffic and has flat nearside beam set wholly below horizontal reference plane.
Inventor: HEIZMANN FRIEDER
IPC: F21S8/12
Filed: 1993-08-18
Abstract: The headlamps of a vehicle project differing beams dependent on their respective nearside and offside positions to minimise glare for oncoming traffic. With respect to a vertical beam-setting screen (17) placed in front of the vehicle the nearside unit projects a flat horizontal beam (20) which is wholly below a horizontal of reference (HH) and symmetrical about a vertical reference (VV) with reduced intensity in the area (25). The offside beam is set to illuminate an area (26) which is preponderantly to the nearside of reference (VV) but is permitted progressively greater vertical height wrt the beam's nearside divergence. USE/ADVANTAGE - Offside beam is directed away from approaching traffic and flat nearside beam produces minimum illumination of road surface to reduce reflections from rain which cause glare to oncoming traffic. Affords good nearside illumination and passengers load correction sensor need control only horizontal i.e. nearside beam.

Title: Clock spring connector
Inventor: KATO HIRONORI
IPC: H01R35/02
Filed: 1994-05-31
Abstract: In the case of a clock spring connector for the electrical connection between a steering wheel and a stationary part of the steering system, the torque of a moving element is increased and, in consequence, the winding up and unwinding of a flexible cable of the connector are simplified. A moving element (15) is held in centre holes in a cover plate and a base plate (11, 13) such that said moving element (15) can rotate with respect to a stationary element (10), which element is formed by joining together the cover plate and the base plate via an outer cylinder section (12). A flexible cable (20) is held between the outer cylinder section (12) of the stationary element (10) and the outer surface of the moving element (15). A rotating plate (16) extends along the surface of the cover plate (11), is mounted on the top of the moving element (15) and has a projection (19) in the vicinity of the outer circumference of the rotating plate (16), the projection being engaged with a hole in the hub of the steering wheel. In consequence, force is transmitted between the steering wheel and the rotating plate at a point far away from the rotation centre of the moving element, so that the latter is rotated via the rotating plate with relatively high torque. <IMAGE>

Patent DE-4429178-A1 (DE)
Title: Pyrochemical ignition chain in a gas generator
Inventor: CAFLISCH ERWIN
IPC: B60R21/26
Filed: 1994-08-17
Abstract: Collision-protection systems, such as airbags and belt tauteners, are actuated by means of gas generators. It has been shown that conventional ignition devices induce excessively high initial pressures, so that the systems are overloaded mechanically. A pyrochemical ignition chain in a gas generator (100) contains an igniter (1) which contains a first initial explosive layer (5) and a second initial explosive layer (6). The second layer has reduced detonating violence in relation to the first layer and preferably contains a composition which is the same as or similar to that of the ignition layer (103) provided in the gas generator (100). The two layers (5, 6) are pressed together with one another; the second layer has a reducing effect in the igniter on the initial pressure surge generated, although it meets all the requirements for reliable ignition. A first layer (5) of trizinate and a 2nd layer (6) of boro-potassium nitrate have proved appropriate. The effect of the pyrotechnic chain can be controlled by a variation in the masses of the two layers (5, 6). <IMAGE>
