Title: Container-tank full sensor-indicator using ultrasonic transceiver - stores fixed and false echo profile and subtracts from received signal to determine real amt.
Inventor: FEHRENBACH JOSEF DIPL ING
IPC: G01S7/527
Filed: 1992-10-12
Abstract: The container-full indicator consists of A/D converter (2) receiving echo signals from ultrasound pulse illuminated surface of container contents. Echo pulses are filtered and digitised. A microprocessor (4) with memories (5,7) processes input data. Received echo pulses include returns from fixed objects in tank or container. A profile of return pulses is built up during filling/emptying of the container. The echo from the surface to be measured changes as the operation proceeds. Other fixed echoes remain constant and are stored as pulses to be cancelled. Pulses are distinguished by time delay from original transmitted pulse. USE/ADVANTAGE - Improved detector performance by rejection of interference and false echoes by storage of calibration data during filling/emptying operation.

Patent DE-4306829-A1 (DE)
Title: Dish-shaped fastening anchor for detachably fastening a grinding ring (abrasive ring, ring wheel), connected thereto, to the end of a drive shaft
Inventor: HOLZAPFEL LOTHAR
IPC: B24D5/16
Filed: 1993-03-04
Abstract: In the field of stone-working, grinding rings are screwed onto rubber couplings by fastening anchors. The disadvantage of the known fastening anchors is that they do not transmit arising forces close to the outer circumference of the rubber coupling and/or by deep penetration into the grinding ring reduce its usable height and/or owing to corrodability endanger the bond between fastening anchor and grinding ring and/or are kept too small for arising axial and radial forces and/or are not connected firmly enough to the grinding ring. The novel fastening anchor is intended to eliminate known disadvantages in an inexpensive manner. Ideally, the rubber coupling (3), which is screwed by its threaded-nut plate (2) to the driving machine shaft (1), transmits arising forces to the outer circumference of its screw plate (4), to which the grinding ring (18) is screwed by means of its fastening anchor (10). The latter (10) has, for this reason, a central circular depression (11). To maximise the usable height (h) of the grinding ring (18), the lowered outer edge (13), claw-like ends (14) and threaded nut (17) penetrate as little as possible and to the same depth into the grinding ring (18). The use of largely corrosionless materials, together with the claw ends (14), ensures an intimate bond between fastening anchor (10) and grinding ring (18). The rectangular basic shape serves to minimise material usage. <IMAGE>

Title: Passive rear-wheel steering assembly for a motorcycle
Inventor: TEUBERT CHRISTIAN DIPL ING
IPC: B62K21/10
Filed: 1993-05-25
Abstract: A description is given of a passive rear-wheel steering assembly for the rear wheel (21) of a motorcycle (1). The steering assembly comprises a customary rear-wheel swinging fork (2) for a motorcycle, which separates between the articulation points (27) of the rear mounting springs (25) and the rear-wheel axle (23) and is then reconnected by five connecting rods (5-9) which are joined in an articulated fashion. The connecting rods (5-9) are arranged in such a manner that in comparison with the front part of the rear-wheel swinging fork (3), for the rear part of the rear-wheel swinging fork (4) and the rear wheel (21) attached thereto only one degree of freedom, namely a rotational motion about the steering axle (24), is still possible. The steering axle (24) is arranged in such a manner that the lateral force of the tyres sets a steering angle which allows the lateral force of the tyres further to increase. Furthermore, there is attached between the front (3) and the rear (4) part of the rear-wheel swinging fork a stiffening means (10) which returns the rear-wheel steering assembly to the central position. The rear-wheel steering assembly increases the damping of the swinging oscillations of motorcycles and hence increases the active safety. <IMAGE>

Title: Method for controlling the fuel feed in a mixture-compressing internal combustion engine
Inventor: KOLB HARTMUT DIPL ING
IPC: F02B77/08
Filed: 1993-07-28
Abstract: A method for controlling the fuel feed in a mixture-compressing, multi-cylinder internal combustion engine is described, the exhaust gas of which is cleaned by means of a catalytic converter device arranged in the exhaust line. It is proposed to interrupt the fuel feed to at least one cylinder as necessary as a function of the exhaust gas temperature. In order to be able to ensure optimum protection against excessive temperatures in the full load range with, at the same time, a minimum fuel consumption without adversely affecting the efficiency of the catalytic converter in the partial load range, it is proposed to use an exhaust gas temperature (synthetic exhaust gas temperature) to be expected as a function of operating parameters of the internal combustion engine as measured variable for the exhaust gas temperature.

In order to be able to match the reaction apparatus to different operating conditions with simple construction and the lowest possible expenditure in terms of apparatus, without a skew temperature profile in the reaction vessel being established, at least two pumps (3, 4) are provided, each of which is connected to a separate annular duct (3a, 3b or 4a, 4b) for the feed or removal of the heat transport medium. These annular ducts (3a, 3b; 4a, 4b) are constructed with a flow cross-section continuously decreasing or increasing in the direction of flow of the heat transport medium (Fig. 1). <IMAGE>
Patent DE-4329049-A1 (DE)
Inventor: HEINRICH DROS
IPC: G02B7/06
Filed: 1993-08-28
Abstract: The invention relates to a binocular fieldglass having at least one adjustable optical component.

In this arrangement, the adjustable optical part is accommodated by a housing tube. In addition, the telescope has between the two telescope halves a further axis which is aligned essentially parallel with respect to the two optical axes and in which an axis member is arranged. According to the invention, the axis member has a longitudinal slot in which an adjusting member is arranged which is displaceable along the longitudinal axis of the axis member. This adjusting member is adjustable in the longitudinal slot from outside the telescope, its axial movement being coupled to the movable optical part in at least one telescope half which contains the optical part to be adjusted. <IMAGE>

Title: Method and circuit arrangement for electronically igniting fluorescent lamps
Inventor: SIEVERS ELMAR DIPL ING
IPC: H05B41/04
Filed: 1993-08-25
Abstract: The invention relates to a method and a circuit arrangement for delay-free and flicker-free igniting (starting) of fluorescent lamps. In the case of the method according to the invention, only the positive half-cycles are used for heating the lamp electrodes, in order to reduce the current-limiting action of the inductors which are present in the lamp circuit. This makes it possible to achieve the emission, which is necessary for an ignition, in the fluorescent lamp after a shorter time with a higher heating current. In a proposed circuit arrangement, this is achieved in that a MOSFET (3) and a diode (6) are arranged in the heating circuit in such a manner that after the MOSFET (3) has been driven high only the positive half-cycles heat the lamp electrodes (1a, 1b) and the MOSFET (3) is reverse-biased again after a defined time, as a result of which the ignition pulse is induced. The circuit arrangement can be accommodated in the conventional housings of bimetal starters (glow igniters glow starter switches) or known electronic starters, so that the invention can be used instead of present starters. <IMAGE>
