The sealing material (3) preferably also covers the inner wall surface of the guide opening and the outer rims of the valve disc (2). <IMAGE>
Patent DE-3507491-A1 (DE)
Inventor: MUELLER ROBERT
IPC: F16D35/00
Filed: 1985-03-02
Abstract: An arrangement for a four wheel drive motor vehicle which increases the rotational moment transfer from the front axle to the rear axle in the case of a large rotational speed differential between the two axles. The arrangement includes a lamella or plate clutch arranged between the front axle and the rear axle. The front axle is directly driven by the gear change transmission and the rear axle is indirectly driven by the front axle. A one way clutch and a reducing transmission are interposed with respect to the plate clutch in such a way that the characteristic curve for rotational moment transfer versus axle rotational speed differential exhibits a flat slope during normal driving conditions (relatively small speed differentials) and an increasingly steep slope during hazardous driving conditions (relatively large speed differentials).

Title: Hydrostatic drive of auxiliary units of a vehicle
Inventor: ALTMANN UWE DIPL ING
IPC: F02B67/08
Filed: 1985-08-20
Abstract: The hydrostatic drive of auxiliary units of a vehicle has preferably two fixed displacement pumps (11, 12) driven by an internal combustion engine (10), to each of which pumps a flow control valve (15, 37) is connected on the output side. Hydraulic motors (24, 27, 38, 48) of auxiliary units of the vehicle are fed by the fixed displacement pumps. This relates in particular to the drive of the generator, the charge air compressor, the air compressor for the brake system and for the fan of the radiator (62). Electrically adjustable proportioning valves for speed control, which are actuated by an electronic control unit (53), are assigned to some of the hydraulic motors. The speed of the internal combustion engine is constantly fed to the electronic control unit by way of a speed sensing unit (54), and in particular, also by way of a speed sensing unit (51), the speed of the charge air compressor (25). Some of the hydraulic motors are connected in parallel, some in series. With such a design of a hydrostatic drive very precise and economic operation of the auxiliary units is achieved at relatively low cost. <IMAGE>
Patent DE-3533848-A1 (DE)
Title: Method and circuit arrangement for synchronising asynchronous digital video signals
Inventor: LOOS ROLF DIPL ING
IPC: H04N21/43
Filed: 1985-09-21
Abstract: The method is based on the finding that after the analog signals have been subjected to low-pass filtering, signal discontinuities of a particular magnitude can no longer occur in the digitised video signals. These signal discontinuities can therefore be advantageously used for representing the synchronisation information. The circuit arrangement comprises a recoding device for recoding the bit sequences which, after bit shifting and addition of parts of the video data, can be erroneously read as synchronisation information.

Title: Device for forming stacks from a plurality of sheet-like individual products comprising paper, cellulose wadding or the like
Inventor: FEHST JUERGEN
IPC: B65H29/46
Filed: 1986-04-04
Abstract: Device for forming stacks from a plurality of sheet-like individual products comprising paper, cellulose wadding or the like. Sub-stacks (15, 16, 15', 16') are fed via a conveyor belt system (1, 2, 3, 4) to a collection device (SA) and a stacking device (ST) following the latter. In the collection device, each second one of the arriving sub-stacks (15) is fed to a collection cylinder (10) and, after one rotation, laid on a downstream sub-stack (16). The collection cylinder (10) is driven by drive belts (2) looping around it and the sub-stacks (15) are guided between the drive belts (2) and the cylinder surface. To avoid an increase in the speed of the collection cylinder (10) during the removal of a sub-stack (15), a compensating device containing deflector rollers (7, 8) connected upstream and downstream of the drive roll (5) for the drive belts (2) is provided. The deflector rollers (7, 8) arranged on a displaceable sliding carriage (6) are moved such that, when the sub-stack (15) is placed on it, the circulation velocity of the drive belts (2) is reduced. In the stacking device (ST), the sub-stacks (15', 16') are pressed by means of an ejector device (17, 22), which can be moved up and down, through the conveying system onto a stack (S). In this process, the sub-stacks (15', 16') are braked by means of a brake device (24, 25) acting at the trailing end of the sub-stack. <IMAGE>

Patent DE-3630873-A1 (DE)
Inventor: GAAL SANDOR
IPC: A01B59/042
Filed: 1986-09-11
Abstract: The hitching device for agricultural tractors has two lower links 7 which form an intrinsically rigid unit and which are each pivotable by means of a lifting cylinder 13 about a transverse axis 5 with the effect of a raising and lowering of the implement, selectively allow the implement to oscillate about an axis extending centrally in the longitudinal direction of the vehicle and are vertically adjustable relative to one another in respect of their end connection points for the implement. To extend the possibilities of use of such a hitching device, whilst preserving a simple design, the transverse axle 5 is mounted so as to be laterally displaceable and pivotable in a vertical transverse plane. In this way, the lower links 7 can assume any necessary position actively as a result of an appropriate control of the position of the transverse axle 5 or passively via the implement. Recommended for publication in conjunction with the abstract: Fig. 1. <IMAGE>
