Title: Device for the optoelectronic detection of physical measured variables
Inventor: WIESMEIER ALBERT DIPL PHYS DR
IPC: G01D5/30
Filed: 1988-07-23
Abstract: A device is proposed for the electronic detection of a plurality of physical measured variables, which are obtained by means of a sensor arrangement consisting of a plurality of fibre-optic measured-value transmitters (sensors) which can be interrogated. Analog sensors are provided as measured-value transmitters; however, sensors which act digitally can also be used, mixed with such analog sensors, e.g. like optical limit-value transmitters. Each individual fibre-optic sensor is connected to a light emitter and a light receiver, in each case via an optical connection. The individual sensors are either loaded cyclically with stimulating light, or their continuously present electrical measured signals are cyclically interrogated. The device consists of two parts, namely an acquisition and transmitting part and a receiving and evaluation part. The connection of the two parts can be produced by means of a single light guide. Alternatively, the connection from the first to the second part can be produced by means of a wire transmission path, a radio transmission path, a microwave transmission path or an infrared light transmission path, so that the measured variables can also be obtained by telemetry.

Patent DE-3842334-A1 (DE)
Inventor: PFEFFER PETER
IPC: B62D5/04
Filed: 1988-12-16
Abstract: In an assisted steering system for a vehicle, an electric motor acts on the steering column. The system is characterized in that the additional torque applied by the electric motor is controlled in fonction of the steering torque required for steering and of the total steering torque applied. The additional torque therefore depends on the torque applied by the driver to the steering wheel as well as on the torque transmitted by the steering device to the wheels to be steered. The electric motor is actuated via an actuator (6) by a controller (5) to which an additional torque M*R, dependent on the vehicle speed, is transmitted. The controller has a dead element which produces the characteristic curve and which effects control only when the torque M*R acting on the controller (5) exceeds a certain limit value. This results in an excellent impression of contact with the road for the driver and optimally assisted steering.

Abstract: The present invention relates to a louvred lighting fixture fitted with a bar-shaped fluorescent lamp, in which the fluorescent lamp is arranged centrally in the upper region of a box-shaped lighting fixture housing (10) of relatively large extent in width. The light exit opening is essentially subdivided into three panels of the same width, that is to say a central region (10a), which is bounded by two contoured reflectors (14) extending in the longitudinal direction. The two side panels (10b) are bounded in each case by a contoured reflector (14) and a reflector (13) extending in the longitudinal direction, which in each case extends in a curved manner over a corner region into the vicinity of a housing ceiling (11). The panels are subdivided in the transverse direction by numerous cross vanes consisting, in each case, of two parabolic branches in a V-shaped arrangement, the cross vanes (15) being arranged parallel to the ceiling in the central panel, and the cross vanes (16) being arranged approximately in the diagonal direction in the side panels. Owing to the arrangement of the reflectors, in the lighting fixture according to the invention a portion of the light flux exits in a primary fashion and a portion exits in a secondary fashion, a glare suppression of the light fluxes being achieved by the cross vanes in all panels.

Filed: 1989-02-24
Abstract: The invention relates to a lorry with a removable tipping container for receiving and depositing containers, silos, pallets or the like, two carrying arms which can be swivelled with the aid of hydraulic cylinders being provided. The invention consists in the fact that the hydraulic cylinders are constructed in the vertical direction as multiple hydraulic cylinders. Preferably, two hydraulic cylinders are provided arranged one on top of the other and operating in parallel. The advantages achieved with the invention consist in the fact that the width of lorries with a removable tipping container is utilised to the best possible extent in order to fully utilise the useful load or the maximum loading width of the vehicle. Thus, with a tipping container lorry according to the invention, for example containers, pallets or the like whose width is for example 2,250 mm can be received. It is also possible with the new lorry with a removable tipping container to receive so-called Europallets in two rows next to one another, which means a doubling of the loading capacity in comparison with the current mode of operation. <IMAGE>

Filed: 1989-04-29
Abstract: A sequence of four high frequency pulses is directed at a specimen. The first, weak pulse is selective for the nuclei of a first group. The second, weak pulse, selective for a second group, transforms the magnetisation of all nuclei into a multiple quanta coherence state. The third, strong pulse induces a correlated z-order state.  A dephasing pulse is applied before the fourth, weak pulse which is selective for the first group which it converts into a single quantum coherence state, enabling detection of first group resonance. USE/ADVANTAGE - For detecting nuclear spin resonance spectra of specimens with groups of nuclei of same type. Enables display of only one group's signals.
Patent DE-3918428-A1 (DE)
Inventor: NAGLER FRANZ DIPL ING
IPC: F16H59/54
Filed: 1989-06-06
Abstract: In the automatic control of a motor vehicle friction clutch (1), the clutch is disengaged when the vehicle is stationary and thus, despite the fact that the engine (3) is running and the gear is engaged, the driver can leave the vehicle. In the case of a fault of the clutch system causing engagement of the clutch, the vehicle may set itself in motion. This is prevented by an arrangement in which, when the clutch (1) is engaged with the vehicle stationary, with the engine (3) running and the gear engaged, the brake pedal (21) must be actuated substantially continuously. If during a predetermined time period of for example two seconds at maximum the brake pedal (21) is not actuated, then the engine (3) is shut off or the change- speed gear (5) is set into its neutral position. <IMAGE>
