Patent DE-3810347-A1 (DE)
Title: Pressure medium control device
Inventor: FASSBENDER ROLF
IPC: B62D5/09
Filed: 1988-03-26
Abstract: A pressure medium control device serves to control a servomotor (1) of a motor vehicle steering system. The servomotor (1) can be adjusted either by means of a hydrostatic steering system (2) or by means of an automatic steering system (4). In the neutral position, a pilot stream flows to the automatic steering system (4) through the steering valve (6) of the hydrostatic steering system (2). In order to obtain sufficient adjustment speed for the servomotor (1) in the event of a steering process of the automatic steering system (4), apart from the pilot stream, a relatively large stream of oil is fed to the automatic steering system (4) via a valve (42) by passing an orifice (16) which maintains the pilot stream. This valve (42) has, in its switched position, an orifice (42A) with a larger cross-section than the orifice (16). The larger orifice (42A) is matched to the operating requirements of the automatic steering system (4). When one of the two discharge inhibiting valves (32 or 33) in the automatic steering system (4) are actuated, the valve (42) can be moved into its switched position by the rise in pressure which then occurs in a line (12). <IMAGE>
Patent DE-3817217-A1 (DE)
Inventor: LORENZ DIETER DIPL ING
IPC: H02G/
Filed: 1988-05-17
Abstract: A compressed gas-insulated bus between a metal-enclosed, compressed gas-insulated high-voltage switching installation and a transformer. The compressed gas-insulated bus, with or without a compensator, serves to connect a transformer to a metal-enclosed, compressed gas-insulated high-voltage switching installation. Since the transformer must sometimes be replaced, the gas-insulated bus should provide an as large as possible, compensable tolerance zone for the position of the transformer connection. For this purpose, the transformer connection to the gas-insulated bus with a compensator is connected by means of a first rotary flange to one end of a Z- or U-shaped enclosed compressed gas-insulated bus connection member, the other end of the connection member being connected to the gas-insulated bus proper by means of a second rotary flange. The compensable tolerance zone is determined by twisting this gas-insulated bus connection member and by the allowable angular movement of the compensator, whereby the allowable axial movement of the compensator can be disregarded. In a gas-insulated bus without a compensator, the transformer connection and the gas-insulated bus are each connected via respective rotary flanges to respective Z-shaped gas-insulated bus connection members with each connection member being connected to the other via further rotary flanges. Such a gas-insulated bus is disposed between a transformer and a compressed gas-insulated high-voltage switching installation of an electric supply plant.

Title: Plug-in connection which can be pre-mounted on the socket side
Inventor: MUECHER HORST ADOLF
IPC: F16L25/14
Filed: 1988-06-30
Abstract: The plug-in connections each comprising an elastic sealing insert (2) and a reinforcement ring (1) are suitable for the shearing-resistant sealing of sockets (7) having differently sized radial internal diameters, while simultaneously ensuring the uniformity of the bases of the pipe connections, in that reinforcement rings (1) of said plug-in connections are matched, by different radial external diameters, to the radial internal diameters, which, for standardisation or other reasons, are of different sizes, of the sockets (7) of pipes and components (8) of the same nominal diameter (DN). Since these reinforcement rings (1) having different radial external diameters can usually be produced in a simple manner, e.g. as axially short portions of extruded plastic pipes, the plug-in connections can each be manufactured with the same dimension of sealing inserts (2) and can thus be adapted, in a favourably priced, but functionally reliable manner, to the differently sized radial internal diameters of the sockets (7) of pipes and components (8) of the same nominal diameter (DN). <IMAGE>

Patent DE-3831663-A1 (DE)
Title: Fuel injection system
Inventor: HAERTEL GUENTER DIPL ING
IPC: F02M51/02
Filed: 1988-09-17
Abstract: Fuel injection systems of this type are provided for internal combustion engines which are used in vehicles and are therefore subject to exacting requirements with regard to accurate and fault-free fuel metering. Known systems have a component cost. It is not possible to determine the actual value of the fuel injection quantity. They have the inherent disadvantage that vapour bubbles occurring in low-boiling fuels can interrupt the fuel injection. In order to overcome the said disadvantages the new fuel injection system has the characteristics that the actual value sensing system is formed by a measuring cylinder with free piston, which divides the measuring cylinder into two chambers, of which the first chamber is connected to the fuel feed system and by way of a solenoid valve forming the metering system to the return system, and the second chamber by way of control bores connects a rotating distributor, forming the control device, either to the fuel feed system or to an injection line assigned to each cylinder of the internal combustion engine. The new fuel injection system can supply the individual cylinders of the internal combustion engine with fuel. The start and end of injection can be varied in order to achieve optimum exhaust, consumption and power output values over wide ranges.

Abstract: The invention concerns an indicator for determining the variation over time of an event by reaction of a first chemical compound with a second chemical compound, which results in a visible colour change. The first chemical compound has a surfeit of electrons and the second chemical compound has a deficit of electrons. When the compounds are brought together simultaneously or consecutively, the course of an event is initiated. The invention also concerns further developments of this basic concept as well as a process for obtaining such an indicator, in which a solution of a compound with a surfeit of electrons is produced in a suitable solvent, if necessary in a solution of a substrate as a carrier, and at least one layer of the solution so obtained is applied to a preparation and then dried. A solution of a compound with a deficit of electrons is produced in a suitable solvent, if necessary in a solution of a substrate as a carrier, at least one layer of the solution so obtained is applied to the layer of the compound with a surfeit of electrons applied to the preparation and dried. This initiates the course of the event. The invention also concerns individual developments of this process and uses of such an indicator in products which exist for a limited time or can be kept for a limited time.
