Patent DE-4313497-A1 (DE)
Title: Method and device for determining the direction and speed of an object
Inventor: BELLOF ANDREAS
IPC: G01P13/04
Filed: 1993-04-24
Abstract: The invention relates to a method for determining the direction of motion of an object which can be moved in two mutually opposite directions relative to a speed measuring device by means of which the speed and the direction of movement of the object are determined as a function of two measurement signals which are phase-shifted relative to one another. In accordance with the invention, a typical sequence of level changes in the two measurement signals is stored for at least one of the two directions of motion, and the decision on the direction of motion of the object is performed as a function of a comparison of the change in level of the current measuring signals in a prescribed time interval with the stored sequence of changes in level. A direction signal is then generated on the basis of this decision.
Patent DE-4314999-A1 (DE)
Title: Vacuum-lifting device
Inventor: GERLACH DIETER
IPC: B66C1/02
Filed: 1993-05-06
Abstract: What is proposed is a vacuum-lifting device having a housing (2), into which is integrated the valve mechanism (3) of a change-over valve (4) communicating with an atmosphere duct (25), with a vacuum duct (26) and with a suction duct (23). There projects into the housing (2) a carrier part (8) which is displaceable relative to the latter and which carries a suction plate (5), in which is formed a suction chamber (18) communicating with the suction duct (23). The carrier part (8) forms the actuating member (14) for the change-over valve (4). When, during the handling of the device, the suction plate (5) is in a position near to the housing (2), the change-over valve (4) assumes a ventilating position, in which the suction duct (23) communicates with the atmosphere duct (25). In contrast, when the suction plate (5) is in a position further away from the housing (2), the suction duct (23) is connected to the vacuum duct (26), so that an article (7) to be transported can be sucked up on the suction plate (5). In order to avoid losses when there is no article (7) present, an especially automatically switching flow valve (35) is inserted into the suction duct. The actuation of the valve mechanism takes place purely mechanically as a result of a relative movement between the carrier part (8) and the housing (2), so that, altogether, an arrangement of very simple and compact design is obtained. <IMAGE>

Title: Anti-theft device as an immobiliser on a motor vehicle
Inventor: LEDENDECKER INGO DIPL ING
IPC: B60R25/04
Filed: 1993-05-21
Abstract: The invention relates to an anti-theft device as an immobiliser on a motor vehicle. The latter comprises a manually activated immobiliser switch (28) by means of which the operation of a component which is necessary for the vehicle to function, in particular an electronic engine control unit (31) is blocked. According to the invention it is proposed that an anti-theft security code is stored in a memory of the combined instrument electronics (11). An enabling code can be entered as a number by means of a control element (9, 10) for inputting digital variables. A comparison of the stored anti-theft security code with the enabling code which is input manually is carried out in the combined instrument electronics (11). When identity is established, the operation of the blocked component (31) is enabled again. Thus, an effective anti-theft device which can be actuated as desired can be realised in a simple and cost-effective way. <IMAGE>
