Patent DE-3817270-A1 (DE)
Title: Jet regulator
IPC: E03C1/08
Filed: 1988-05-20
Abstract: A jet regulator (1) (Figure 1) exhibits a jet-regulator housing (3), in whose through-passage channel (4) a jet-regulator insert (5) is introduced. In order to reduce a backflow pressure which builds up increasingly as a result of dirt on the rear of the insert, the through-passage cross-section of the jet regulator can be increased, upon exceeding a predeterminable backflow pressure, in that the jet-regulator insert (5) is released out of its normal-operation position and either falls out of the jet-regulator housing (3) or else passes into an initiation position in which there is formed, for example around the insert, an annular channel which increases the overall through-passage cross-section. The jet regulator according to the invention can thus also be used on appliances which are sensitive to backflow pressure, such as, in particular, instantaneous heaters or the like. <IMAGE>

Patent DE-3905162-A1 (DE)
Inventor: GOYAL RAMESH CHANDRA
IPC: H03M1/18
Filed: 1989-02-20
Abstract: A high resolution analog to digital (A/D) converter amplifies and filters a magnitude difference between a pulse width modulated offset voltage VOFF and an input voltage VIN to produce an amplified filtered difference voltage VO, the duty cycle of offset voltage modulation being adjusted such that the magnitude of the difference voltage VO is within a narrow input voltage range of a recirculating remainder A/D converter 18. The amplified, filtered difference voltage VO is converted to digital data D1 by the recirculating remainder A/D converter 18. A microprocessor 20, which controls the offset voltage, combines the result with the magnitude of the offset voltage to produce a comparatively high resolution digital representation of the input voltage. During a first pass an autoranging circuit 12 divides the input voltage VIN by a factor of 1,000 and supplies the resulting voltage directly to A/D converter 18. in response to the output of the A/D converter 18 during the first pass the microprocessor 20 adjusts the gain of autoranging circuit 12 to provide a voltage which is a substantial portion of the input voltage range of the A/D converter 18 during a second pass. For the third pass switches S1 and S2 are closed and switch S3 opened; the offset voltage VOFF represents the output of A/D converter 18 during the second pass less a fixed non-zero amount. The output is derived from the outputs of the A/D converter 18 during the second and third passes and the gain factor supplied to the autoranging circuit 12. <IMAGE>

Inventor: ECKERT HORST DIPL ING
IPC: B62D61/12
Filed: 1989-06-21
Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift-axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the position of the one end of ram representing the axle load signal to be obtained. 2.2 In order to simplify the previously described device, the invention proposes the replacement of the three-dimensional characteristic by a two-dimensional contour (20, 21) and the arrangement in the slide (22, 24, 26) of a cylinder unit (24) which can be subjected to the pressure of lift bellows (1), which unit adjusts the slide length in a pressure-dependent manner. As a result, an adjustment of the position as a function of the slide length is superimposed on the adjustment of the position of the end (26) or the ram (22, 24, 26) by the contour (20,21). 2.3 The preferred area of application is vehicle technology. <IMAGE>
