Title: Hydrostatic steering device
Inventor: MADAUSS HANS-JUERGEN
IPC: B62D5/097
Filed: 1985-02-11
Abstract: The invention relates to hydrostatic steering devices. Devices of this kind are used in fully hydraulic steering systems and serve preferably for steering heavy, slow vehicles. The object of the invention consists in increasing the volumetric efficiency and in improving the working accuracy, the safety and the comfort of the steering system. The manufacturing outlay and the use of material are to be reduced. The technical object consists in largely restricting the flow of leakage oil inside the steering device, in particular in the case of metered pressurised oil, making the control system shorter and, to a certain extent, making tolerances wider. According to the invention, this object is achieved in that the interior of the control system is constructed as a pressurised compartment. The pressurised compartment has openings for the feed-in, for the discharge and for the expulsion system. <IMAGE>

Patent DE-3523726-A1 (DE)
Inventor: KRAEMER MANFRED DIPL ING
IPC: F02D1/04
Filed: 1985-07-03
Abstract: A centrifugal adjuster for a fuel injection pump governor having a driving part driven at an rpm in synchronism with the engine and having a torsionally elastically coupled flyweight holder guided in a rotational guide. Via a step, beyond a predetermined rotational deflection, the centrifugal adjuster displaces the flyweight holder axially with respect to the driving part, so that a jolt-like stroke effected by means of the step is superimposed on the regulating stroke effected via the flyweights of the centrifugal adjuster whenever the rpm is at a low level, for instance at idling rpm. As a result, a friction that leads to see-sawing of the engine and exhibits pronounced hysteresis is shaken out of the governor.

Title: Multipole electrical connection, which is constructed as a plug connection, between two components which are connected to one another in an articulated manner, especially between the bodywork and side door of motor vehicles
Inventor: HEUSER EDGAR
IPC: H01R13/24
Filed: 1985-10-10
Abstract: In the case of a multipole electrical plug connection between two components which are connected to one another in an articulated manner and which may be vehicle bodywork having an electrical power source and a vehicle door which is equipped with electrical loads, the male plug part which is allocated to one component (for example vehicle bodywork) has a first housing which accommodates electrical contacts and to which a centring pin is attached. The female plug part, which is allocated to the other component (for example a vehicle door) has a second housing which contains electrical mating contacts and in which a centring recess is provided which interacts with the centring pin. The first housing, including the centring pin, is arranged such that it can move in a limited manner in a housing cage - at least within a plane which is directed transversely with respect to the longitudinal axis of the centring pin. Such an electrical plug connection makes possible automatic compensation for relatively large dimensional deviations (tolerances) resulting from manufacture and assembly on those components which are connected to one another in an articulated manner. The electrical plug connection is particularly suitable for modular construction in the case of the bodywork and door assembly of passenger vehicles.

Title: Rolling mill, in particular continuous tube rolling mill
Inventor: HERMES ROLF
IPC: B21B17/14
Filed: 1985-11-11
Abstract: The invention relates to a continuous tube rolling mill with grooved rolls which are arranged in series and are mounted in pairs, each offset by 90 DEG  relative to the other, in chocks which can be adjusted relative to fixed supporting parts in order to change the rolling pass. Known rolling mills of this kind have roll stands in which the grooved rolls are mounted by means of their chocks. The disadvantage in known designs are the spaces between the roll stands resulting from their construction. Since the space affects the length of the mandrel bar required, the spaces should be kept as short as possible. It is the object of the invention to provide a simplified rolling mill with the narrowest possible spacing between the grooved rolls and great stability. To achieve the object, a box-shaped holding structure consisting of pairs (6, 7) of beams parallel to one another and to the axes of the rolls is proposed, each pair (6) of beams being connected at the ends to the adjacent pair (7) of beams, which is offset by 90 DEG  in a parallel plane, and the chocks arranged between each pair (6 and 7) of beams being braced relative to the chocks (5) of the adjacent pair (6 or 7) of beams. <IMAGE>

Abstract: PCT No. PCT/EP87/00578 Sec. 371 Date Mar. 5, 1989 Sec. 102(e) Date Mar. 5, 1989 PCT Filed Oct. 7, 1987 PCT Pub. No. WO88/03610 PCT Pub. Date May 19, 1988.A cylinder has a roll shell that rotates around a fixed central axis. A first chamber arranged inside the cylinder is filled with liquid and transfers a supporting hydraulic force from the central axis to the shell. The first chamber is linked by a throttle to a second chamber located as well inside the cylinder, and in which is arranged for example a hermetically closed rubber hose filled with gas, so that the second chamber is at all times only partially filled with liquid. Thus, the volume of liquid contained in the second chamber can rapidly change when there is a change of pressure in the first chamber, so when the shell tends to vibrate, liquid flows back and forth through the throttle, converting wave energy into frictional heat by means of fluid friction, and thereby damping the vibration.
