Patent DE-3838336-A1 (DE)
Inventor: SEDELMAYER JUN FRANZ XAVER
IPC: B60P3/07
Filed: 1988-11-11
Abstract: In known vehicles, the weight of the platform and load it supports acts with a large lever arm on the rear axle, placing it under a considerable load. At the same time, the load on the front axle of the vehicle is reduced. The resultant undesirable effects on the tilting torque of the vehicle, and in particular on its driving characteristics when loaded, are eliminated as follows: the platform (6) can pivot beyond the chassis frame (2) in the longitudinal direction of the latter about at least one extensible joint rod (7) mounted on the rear axle (11) or its leaf springs (5). One end (20) of the joint rod (7) is articulated with the rear axle (11) or its leaf springs (5) and the other end (10) is articulated with the plateau (6). The coupling point of this other end (10) describes a curved trajectory (19) above the rear axle (11) when the platform (6) moves from its tilted position (Fig. 2) to its horizontal position (Fig. 1) and vice versa.

Title: Circuit arrangement for monitoring the current of electrical loads
Inventor: ARNOLD KARL-HEINZ
IPC: H02H1/04
Filed: 1988-12-21
Abstract: A circuit arrangement for monitoring the current of electrical loads is proposed, by means of which the current is monitored without delay by means of comparison with a predetermined limit value adapted to the permissible current variation, using inexpensive components. For this purpose, the measurement signal of the current measuring element (12) is applied to one input of a comparator (19), the other input of which is connected to the output of a D/A converter (22), the input of which is connected to an output of a microcomputer (10) via a bus line (23). Whenever one of the loads to be monitored is switched on, a limit value associated with it and controlled graded in time is applied via this microcomputer output via the converter (22) to the comparator input connected thereto, and when the instantaneous load current deviates by a predetermined amount from the instantaneous limit value, a fault signal occurs at the output of the comparator (19) (Figure 1). <IMAGE>

Title: Fibre reinforced component prodn. - by placing lower tool with reinforcement, resin and flexible upper tool sealed at edges in pressure chamber etc.
Inventor: TRIEBEL GEORG
IPC: B29C35/08
Filed: 1989-11-29
Abstract: In the prodn. of fibre reinforced plastic components, initially layers of fibrous reinforcement are positioned in a tool cavity and a cross-linkable resin is poured onto the fibres. An upper tool component, e.g. a flexible sheet or film is placed over the reinforcement and sealed around the edges. The complete assembly is then subjected to overall pressure in a chamber. A tube from the cavity between the two tool components evacuates air from within the fibrous material and acts as an outlet for excess resin squeezed out under the overall pressure. The tube is sealed off prior to final resin curing. USE/ADVANTAGE - The process produces fibre composite components, prevents escape to atmosphere of harmful vapours e.g. styrene, ketones and requires less contact with potentially harmful materials.
Patent DE-4011132-A1 (DE)
Inventor: HERDEN WERNER DIPL ING DR
IPC: G01L9/00
Filed: 1990-04-06
Abstract: Described is a pressure sensor (11) in which a pre-tensioned spring (19) designed in the shape of a plate is located between the sensor hammer (16) and seat (21) in such a way that the outer edge of one side of the spring rests against the hammer (16) and the centre of the other side of the spring rests against the seat (21). When pressure acts on the sensor (11), the volume of the sensor is modified and the electrical resistance of the resistive layer (26) on the sensor seat (21) is progressively short-circuited. This gives a relatively high measurement sensivity, making it unnecessary to have a signal-processing or signal-amplification circuit inside the pressure-sensor housing (10). The pressure sensor (11) is therefore simple and cheap to manufacture.
