Inventor: MILDE FRIEDHELM PROF DR ING
IPC: G01L3/00
Filed: 1992-09-04
Abstract: The mechanical torque provided by the output shaft of an electric motor is determined by measuring the voltage (Ua..Uc) and currents (ia..ic) for each motor phase (L1..L3), or for two selected motor phases. The measured values are fed to an analog calculation stage, or a digital microprocessor for determining the corresponding torque using a defined function. Pref. the calculated torque is provided as a voltage signal supplied to a display and/or regulation circuit. USE/ADVANTAGE - For motor test stand, torque regulation and laboratory drive. Requires no rotational speed measurement, flux measurement and frequency. Avoids problems with strain gauge measurement eg long wait time and high sensitivity to over-load.

Title: Camera with a controllable diaphragm
Inventor: CHIKAZAWA YOSHIHARU
IPC: G03B7/0997
Filed: 1993-02-25
Abstract: It is known to control the duration of the illumination (exposure) and the sensitivity to light (filter response, speed) by means of an iris diaphragm (graduated iris diaphragm, iris). Such known iris diaphragms, designed like this, can only be controlled as a whole. The object is to control the light transmission (transmittance) in a camera pixel by pixel as a function of the ambient brightness. The diaphragm according to the invention consists of pixels which form a matrix and whose transparency can be controlled as a function of the brightness. As a result, the impression of contrasts in the picture is increased considerably so that an impression of a light source is produced which is not too bright. In particular, for cameras. <IMAGE>

Patent DE-4315766-A1 (DE)
Title: Device for protecting and controlling railway vehicles
Inventor: FAHRENBERG PETER
IPC: B61L27/00
Filed: 1993-05-07
Abstract: The two ends of a vehicle configuration (F) are provided with response devices (A1, A2) for transmitting vehicle-side identifications to a track-side reading device (L3). If a vehicle or vehicle configuration passes such a reading device with its tip, the track section (GA3) following in the direction of travel is reported to be occupied. In addition, a memory (S3) is set, which serves to provide the later track-release indication of the track section (GA2) lying behind in the direction of travel. After the memory (S3) is set, a central control station (Z) calls up the vehicle continuously using the vehicle identification reported to it by the fixed device (E3) and thus causes the vehicle to report to it its current positions along with movement data relevant for controlling the vehicle. The calling up of the vehicle to acquire these items of data and the transmission of data which is relevant for controlling the vehicle takes place cyclically. If the vehicle passes the fixed interrogation device (L3) with its end-side response device (A2), the identification transmitted from there is read and transmitted to the central control station. If the central control station determines that the identifications successively transmitted to it from the fixed device (E3) are associated with the same vehicle configuration and are to be assigned to the start and the end of this vehicle configuration, it brings about the termination of the cyclic data transmission, the resetting of the previously set memory (S3) and thus the ...

Title: Transporting device for receiving liquids, preferably beverages
Inventor: BOLLSTROEM HAKAN
IPC: A47G23/06
Filed: 1993-06-11
Abstract: From experience we know that a drinking vessel on a tray which is being carried often starts sliding or topples over in the event of an impact. To prevent this, the problem can be eliminated by a simple solution. Since this invention is not yet on the market, it can only be of benefit. This device is very suitable for, e.g.  - fast-food restaurants  for receiving beverages and food. Since the base of the filled container lies flat on the tray, there is a good retention of the base. Thus, the container is no longer able to slide back and forth during carrying. This invention, consisting of a container (plastic bag) instead of cups which otherwise slide or topple over, is very advantageous.

Title: Warning signal generation method for deflation of tyre on moving vehicle - is regulated by false-alarm-inhibiting signals which are rendered ineffectual after interval corresp. to max. duration of curve negotiation.
Inventor: KREFT JOERG DIPL ING
IPC: B60C23/06
Filed: 1993-11-24
Abstract: Signals from wheel rotational speed sensors (1) are fed through an offset stage (2) and an averaging filter (3) into a stage (4) where vehicular acceleration values are worked out. Fuzzy logic (5-7) assesses the probabilities of false alarms caused by acceleration and curvature of route. A warning lamp (12) is lit (11) when the averages are delayed (15) and switched (14) into a summation filter (10), unless inhibited by computation of high probability that the observed speed changes are attributable to these causes. ADVANTAGE - False alarms arising from tyre pressure variations caused by vehicular accelerations are prevented with security against misinterpretation of rotational speed variations e.g. around curves.

Patent DE-4341234-A1 (DE)
Title: Car headlamps
Inventor: HEIZMANN FRIEDER
IPC: F21V14/06
Filed: 1993-12-03
Abstract: A car lamp has a single light generator (16) with light distributors (20, 21) connected by optic fibres (18). Each distributor has a lens. The relative coordination between the end of a fibre and a lens can be changed to give a different horizontal pattern of emitted light. The adjustment occurs in conjunction with the steering system, so that the maximum intensity is in the travel direction. There is one particular arrangement of fibre relative to distributor for straight-ahead driving and another for when the steering wheel is turned. The adjustment is continuous while the steering wheel is turned. The headlamps can be moved independently depending on whether the curve is left hand or right hand.
