Patent DE-3700986-A1 (DE)
Inventor: BUEHREN HARALD DIPL ING
IPC: F16H61/12
Filed: 1987-01-15
Abstract: The invention is directed to an arrangement for monitoring a computer system with two processors in a motor vehicle. The arrangement provides that the two processors monitor each other to the same extent and that this monitoring occurs in the form of a hand-shake operation in the context of a cyclical data exchange between both processors. In this connection, it is especially advantageous that both processors: can operate fully independently of each other; need not utilize a directly coupled or common I/O-bus; and, are mutually asynchronously operable with different clock frequencies. The arrangement provides a mutual monitoring of two processors to the same extent so that a failure can be localized when it occurs. In this way, the arrangement can distinguish whether a processor has failed or whether an error is present in the peripheral hardware of the processors. For this purpose, the above-mentioned cyclical data exchange between both processors is utilized as an acknowledgement path for the monitoring function.

IPC: G01R15/16
Filed: 1987-01-30
Abstract: A conductive layer or conductive tape located around the wire insulation of a high-voltage cable (1 in Fig. 1), together with a low-voltage capacitor, forms a capacitive voltage divider. The dielectric strength of the high-voltage capacitor is determined by the conductor insulation of the cable. The voltage drop across the low-voltage capacitor is supplied to a test socket located on the cable jacket. The voltage divider can be installed subsequently by a specially shaped connecting sleeve or by specially shaped cable terminations at any point in a cable network. The voltage dividers allow continuous voltage measurement at any number of test points in the cable network. The bandwidth extends from the system frequency up into the MHz range. <IMAGE>

Patent DE-3726318-A1 (DE)
Title: Brake device acting automatically, hydraulically and eccentrically without friction
Inventor: MIEDING GUENTER
IPC: F16D57/06
Filed: 1987-08-07
Abstract: On a shaft to be braked, an eccentric is fitted so that it cannot rotate. Two pistons, which run in two opposing cylinders, bear on the said eccentric with their rear side. Due to the eccentric movement, the pistons are set in a linear motion. Since the cylinders are connected by a line containing an incompressible liquid, they drive this liquid to and fro. A valve, which on closing prevents the movement of the liquid, is located in the middle of the line. These in turn prevent the movement of the eccentric and thereby bring the axle to a standstill. The moving parts run in an oil bath, hence no heating. The brake is more reliable and cheaper.

Title: Two-component housing for a coupling
Inventor: JANKOWSKI MEINRAD
IPC: B61G5/06
Filed: 1987-09-03
Abstract: The two-component housing for a centre buffer coupling of rail vehicles has housing components (1) with housing inserts (3) which contain control circuit connection elements (4, 5) which serve to connect electrical and/or pneumatic and/or hydraulic control circuits. In order to permit automatic coupling, each housing component (1) is provided with an even number of axially protruding guide noses (2) which are arranged around their circumference at a distance from one another, are of corresponding design and are of a width which corresponds to the spacing between the guide noses. The guide noses (2) have guide faces (12, 14) which extend obliquely with respect to the axis of the housing and when the housing components (1) are moved together, ensure on the one hand their axial alignment with respect to one another and on the other hand their alignment with respect to the relative angle of position. The inserts (3) are provided with connection elements (4, 5), of which those of one half of the insert are complementary to those of the other half located on the other side of an axial plane (A). On each side of a plane (S) of symmetry which encloses a right angle with this axial plane (A), the connection elements (4, 5) are designed and arranged to correspond to one another in a mirror-inverted fashion. In this arrangement, this plane (S) of symmetry of the inserts encloses an angle  alpha  of 45@ with an axial housing plane (G) defined by the two guide noses (2) of the housing components (1) (Fig. 2). <IMAGE>
Patent DE-3731044-A1 (DE)
Title: Compressed-gas-operated shooting weapon, especially a recreational weapon which is operated using CO2 gas
Inventor: KUENSTLER GERD-DIETER
IPC: F41B11/724
Filed: 1987-09-16
Abstract: A shooting weapon which is operated using CO2 gas has a pressure chamber in which the gas is stored for firing. The shot is fired by opening the valve which seals the pressure chamber from the weapon barrel. In order to compensate for pressure changes in the CO2 gas resulting from temperature fluctuations, a piston is mounted displaceably in the pressure chamber, which piston acts on the valve spring or the firing spring. In the event of a reduction in pressure, the valve spring or the firing spring is relieved of stress by the piston movement, as a result of which the valve opening time and hence the gas quantity required for firing are increased. This automatic regulation of the valve opening time as a function of the gas pressure ensures a constant projectile muzzle velocity and hence constant firing precision.
