Patent DE-3322334-A1 (DE)
Title: End region of a motor vehicle
Inventor: BAUER ANDREAS
IPC: B62D21/15
Filed: 1983-06-22
Abstract: So that the customary side members (5) in the end region (1) of a motor vehicle do not reduce the space between the wheel wells (2), they extend above the wheel wells (2); the resulting height displacement between the side members (5) and the adjacent bumper (7) of the vehicle is compensated by means of further side members (9) which are integrated in a sound-damping wall (8) which runs below the drive assembly and is releasably mounted, and form at least in the event of a crash a support between a cross member (6) which connects the outer end regions of the side members (5) on the one hand and a further cross member (14) on the other (Fig. 1).

Title: Brake system for motor vehicles
Inventor: KLEIN HANS-CHRISTOF
IPC: B60T13/14
Filed: 1984-01-31
Abstract: A brake system for motor vehicles according to the main patent ... (Patent Application P 3323402.7) has a pedal-operated, multi-circuit hydraulic brake pressure sensor (3), which essentially comprises a brake booster (4) and a master cylinder (5) and is connected to an auxiliary power supply system. Brake pressure modulators (10, 11) for example 2/2 way valves are inserted into the brake pressure lines to the rear wheels. For pressure reduction on the rear wheel brakes (8, 9) a return line leading to a pressure balancing tank (14) is provided into which an openable separating valve (16) is inserted. The pressure reduction on the front wheel brakes (6, 7) is controlled by means of a further separating valve (19), which when reversed to allow free passage briefly closes the power supply system on the inputs of the brake pressure sensor (3). Wheel sensors (S1-S4) and an electronics system (22) for actuating the electro-magnetically controllable brake pressure modulators (10, 11) and the pressure reduction valves (16, 19) are also provided. The brake system is capable both of the open loop control of the brake pressure distribution to the front axle and the rear axle and of closed loop control of the brake slip should locking tendencies occur. A restrictor (13) in the delivery flow of a pressure medium pump (12) of the auxiliary power supply system produces a differential pressure which by way of a hydraulically actuated 3/2-way valve (21) ...

IPC: F25D31/00
Filed: 1984-04-04
Abstract: Small portable compact cooling device with a cooling space which is dimensioned for a drink bottle and into which the cooling device is inserted when not in use and wherein it can be transported with the smallest possible space requirement in luggage etc. The cooling device can contain a compression, Peltier or absorption refrigerating machine and is, as required, connected to the mains supply, possibly also to the on-board supply of motor vehicles or boats. Preferably, a discontinuously operating absorption refrigerating machine with a solid absorption medium is used. The small cooling device can also be used for heating food or keeping food hot, by inserting the cooling device into the housing in such a turned manner that the food passes into the zone of influence of the electric heating for the expeller/absorber. The cooling aggregate can also be suspended, next to the cooling space for a bottle, in a larger coolbox, so that an even more universal use results.

Title: Arrangement for the low-vibration transport of a tensioned web of elastic material
Inventor: AHRENS DIETER DIPL ING
IPC: B65H23/188
Filed: 1984-06-06
Abstract: The invention relates to an arrangement for the low-vibration transport of a tensioned web of elastic material by a series of driven or non-driven rollers. The invention consists in that physical means are provided, by which the ratio of the effective moments of inertia of the rollers and the elasticity constants of the web of elastic material is kept constant from roller to roller. In the case of webs of material with an elasticity constant which has changed in relation to an initial condition, e.g. as a result of changes in temperature or cross-section, the ratio of the mass moments of inertia of the rollers and the elasticity constants of the web of elastic material is kept constant by modifying the distance between the rollers. In the case of webs of material with an elasticity constant which has changed in relation to an initial condition, the ratio of the moments of inertia of the rollers and of the elasticity constants of the web of elastic material is kept constant by modifying the mass moment of inertia of the rollers. <IMAGE>

IPC: B65H23/188
Filed: 1984-06-07
Abstract: The invention relates to an arrangement for regulating web tensions in a device for transporting a web of elastic material, which is under tension, via a series of driven rollers. The invention consists in that, when disturbances are having an effect, to keep set web tension values constant, or to modify set web tension values within predetermined ranges, it is possible to subject roller drives or groups of roller drives (8) which are adjacent in each case to oppositely-directed correcting variables (4). The evaluation of the correcting variables takes place in accordance with the number of roller drives in a group. The sensors for the speed regulating systems of the roller drives or groups of roller drives are mounted as far away as possible from the sensors (1) for the web tension regulating systems. <IMAGE>
