Title: Belt-tightening device for vehicle safety belts
Inventor: WENTKER STEPHAN
IPC: B60R22/195
Filed: 1988-12-28
Abstract: A belt-tightening device for vehicle safety belts is to be produced which is of a simple and operationally reliable design and is composed of a device which moves the belt lock so as to tighten the belt, blocks it at the end of the tightening movement and is activated by a so-called vehicle sensitive system when critical levels of acceleration have been exceeded. This is achieved in the case of the belt tightening device according to the invention by fastening the belt lock in an eccentric fashion to a bush which is longitudinally guided on a rail which is fixed to the vehicle or by fastening it to an annular part which is longitudinally guided on the rail or to a similar component, in that the bush or the like is connected to one end of a tensioning element which is preferably flexible and the other end of which is connected to a pent-up force which is preferably constituted by a prestressed spring and which, when released, imparts a drawing-in movement via the tensioning element to the belt lock, and in that the vehicle-sensitive system controls a locking device, which holds the pent-up force in its prestressed position, in such a way that the said device is unlocked when predetermined levels of acceleration are exceeded. <IMAGE>

Abstract: PCT No. PCT/EP90/00836 Sec. 371 Date Jan. 23, 1992 Sec. 102(e) Date Jan. 23, 1992 PCT Filed May 23, 1990 PCT Pub. No. WO90/15460 PCT Pub. Date Dec. 13, 1990.A frequency-doubled laser contains laser diodes as a pumped light source and a resonator (R) comprising in the stated order a first mirror (5), a laser medium (6), a Brewster plate (7) as a polarizer, a nonlinear crystal (8) for frequency doubling and a plane mirror (9) as an output mirror. The plane mirror ensures that shifts of rays taking place within the nonlinear crystal remain in the radiation area even when returning through the crystal, in contrast to the prior art which uses a concave mirror as an output mirror that causes shifted rays from the nonlinear crystal to be deflected out of the beam path. The inventive measure achieves a laser light that has high efficiency and is virtually free from intensity fluctuations.

Abstract: An automatic control device for motor vehicle windscreen wipers comprises a windscreen wiper motor (19) and a sensor (10) for detecting moisture on the windscreen. An electronic device has means (12-18, 21, 22) which switch on the windscreen wiper motor (19) for a given time-interval when a sensor signal is emitted and means (24) which suppress sensor signals emitted when the windscreen wiper motor (19) is moving. The evaluation of the sensor signals is therefore not affected by the actual wiping operation, and any variations in the wetting of the windscreen can be detected precisely by means of consecutive sensor signals. In addition, one sensor is sufficient for controlling a given wiping interval, and therefore signals for switching on the windscreen wiper motor are superfluous.

Title: A=D conversion of multi-integration principle - charges in first step charge storage for preset, constant time period
Inventor: SONTOPSKI WILLI DIPL ING
IPC: H03M1/06
Filed: 1990-11-23
Abstract: The A/D conversion of current or voltages is based on a multi-integration principle. In the first step, a charge storage is charged by a measuring current for a preset, constant time period, while in a second step, a constant reference current or voltage is connected. The reference current etc. is oppositely polarised and applied up to attainment of a preset voltage threshold with a count of the necessary time. This process is several times repeated. After the last measuring of the counted total value, it is converted by a computor into a digital result value, proportional to the measured current according to a formula related to the system dependent constant and a counter value of a low measuring. USE/ADVANTAGE - For digital current, voltage, and resistance measuring. Improved linearity, and continuous recording of input current.
