Patent DE-4040572-A1 (DE)
Inventor: WINNER HERMANN DIPL PHYS DR
IPC: G01S13/34
Filed: 1990-12-19
Abstract: The invention concerns a method, using electromagnetic waves, of measuring the range and speed of an object; the range being calculated from the difference in frequency of the emitted and simultaneously received waves (FMCW-radar). The frequency difference is measured while the emitted-wave frequency is increasing and while it is decreasing. The speed is calculated from the difference between the frequency differences, while the range is calculated from the mean of the frequency differences.
Patent DE-4104775-A1 (DE)
Inventor: HELLER MARTIN DR
IPC: B60T8/66
Filed: 1991-02-13
Abstract: The invention relates to a method for determining the speed of a vehicle with slip-controlled wheels, which permits a continuous control of the slip of the wheels of a braked or driven vehicle and thus ensures the optimum utilisation of a wheel/carriageway coefficient of adhesion which is insufficient in itself. In this method, cyclically successive process steps are executed:   1. In each case a first wheel acceleration is determined from the measured speeds of the wheels including damping. 2. In each case a second acceleration is formed from this first acceleration in that only that portion of the latter is used which fulfils the condition that a positive or a negative limit value of a change in acceleration with respect to a value of a vehicle acceleration which precedes it in time is not exceeded. 3. An assumed vehicle acceleration is determined from the second acceleration values of all the wheels by forming averages. 4. A value for an assumed vehicle speed is generated by integration of the assumed vehicle acceleration. 5. By evaluating the measured wheel speeds it is determined whether the latter follow the tendencies of the assumed vehicle speed or acceleration and when required corrections of the assumed values are initiated.   <IMAGE>

Patent DE-4116059-A1 (DE)
Inventor: BAUR GUENTER DR ING
IPC: G02F1/1524
Filed: 1991-05-16
Abstract: The invention makes available an electrochromic light valve (1) with an active electrochromic film (2) and a passive electrochromic film (3). Between the two electrochromic films is an electrolyte (4). Each of the electrochromic films is connected to an associated electrode (5, 6). The active electrochromic film can accept electrons from its electrode and ions of a particular element from the electrolyte to become reversibly coloured. The passive electrochromic film acts as a reservoir for ions of the species concerned, donating such ions to and accepting them from the electrolyte. At the operating temperature of the light valve, the passive film is supersaturated with the element which provides the ions of the species concerned. The invention also covers a method of manufacturing the electrochromic light valve and uses of the valve.
Patent DE-4116152-A1 (DE)
Inventor: REMBOLD HELMUT DIPL ING
IPC: F01L1/34
Filed: 1991-05-17
Abstract: The proposal is for a device for adjusting the angle of rotation between a camshaft, especially one for actuating the gas valves of an internal combustion engine, and its drive component (12), the two working chambers (14, 16) of which, consisting of hollow circular segments (30, 34), are connected to a first servo-pressure medium source. In addition, this camshaft adjusting device is extended by a third working chamber (18). The third working chamber (18) is formed from a further hollow circular segment (32) with an existing one (30), by means of which the angle of rotation can be given an additional adjustment. This has the advantage that, in addition to the adjustment facilities provided by the existing two working chambers (14, 16), a separate adjustment may be made for other revolution speed ranges. In particular, a second servo-pressure medium source (58) can be used therefor which can be actuated independently of the first.

Inventor: WEISS WILHELM
IPC: A23L2/00
Filed: 1991-07-12
Abstract: The invention concerns a method for mixing drink components, in particular syrup and water, in which the first component is fed from a reservoir into a metering chamber with a given volume, the amount of the second component required to give the desired concentration measured out, and both components fed into a storage tank. If the reservoir contains an insufficient supply of the first component, the metering chamber is only partly filled with the first component, the amount of the first component introduced into the metering chamber measured and a corresponding amount of the second component measured out. This enables even small amounts of syrup left in the reservoir to be used up, while continuing to produce a drink of the same concentration.
