Title: Brake pressure control system
Inventor: STEIN ULRICH DIPL ING
IPC: B60T8/42
Filed: 1986-08-01
Abstract: In order, by economic means, to reliably prevent overbraking of the rear wheels in a brake pressure control system for hydraulic brake systems on motor vehicles with an antilock device and one or more brake pressure control devices, the pressure relief unit (3) of the antilock device (3) has pressure chambers (4, 5, 6) which can be shut off from one another, the first (4) and the second pressure chamber (5) normally being connected to one another and separated from one another when the antilock control comes into play, whilst the third pressure chamber (6) is sealed off from the other two. <IMAGE>
Patent DE-3626498-A1 (DE)
Title: Method for preventing the formation of secondary membranes in ultrafiltration, especially of milk
Inventor: ROINER FRANZ PROF
IPC: B01D61/14
Filed: 1986-08-05
Abstract: The invention creates a method which enables the development of secondary membranes in the ultrafiltration of liquids which contain proteins and salts, in particular of milk, to be substantially avoided. This is achieved by adding, before the actual concentrate formation, the concentrate phase back immediately into the liquid to be fed to the ultrafiltration filter and by also recycling the permeate phase after it has been subjected to a desalting operation. In this manner the filter throughput is successfully at least maintained during the actual concentrate formation and is not impaired by secondary membrane formation.

Title: Simultaneous extraction installation for removing waste gases during the coke discharging and charging operation
Inventor: HOELTER HEINZ DIPL ING
IPC: C10B27/04
Filed: 1986-09-08
Abstract: The extraction installation possesses a common collecting line with uniform, equal-sized flaps. These flaps are controlled in such a way that, given the greater waste-gas volume during the coke discharging, a plurality of flaps are opened, whereas during charging only one flap has to be opened. The flaps are appropriately constructed. The extraction installation permits, moreover, the admixture of the cooler coke-discharging gases to the charging gases, so that separate cooling of the charging gases is unnecessary. <IMAGE>

Title: Valve arrangement for at least one hydraulic consumer fed by a pump with variable delivery volume
Inventor: ROTH DIETER DIPL ING
IPC: F15B11/16
Filed: 1988-02-19
Abstract: A valve arrangement for at least one hydraulic consumer fed by a pump with variable delivery volume consists of a directional control valve for the consumer, a pilot-control transmitter for the directional control valve, and at least one governor valve for the adjusting device of the pump. The pressure difference occurring at the directional control valve can be so slight that the pump governor does not respond and thus the pump cannot be swung out in the direction of higher delivery volume. This disadvantage is avoided if, instead of the load pressure, the pilot-control pressure is switched to the pump governor, as a result of which the pump is swung out.

Title: Directionally adjustable low-voltage luminaire
Inventor: PUSCHKARSKI THEODOR
IPC: F21V23/00
Filed: 1988-03-02
Abstract: The invention relates to a directionally adjustable low-voltage luminaire having a spotlight mirror cap which emits a light cone. Luminaires of this kind, however, require complicated mounting arrangements to be able to adjust the light cone in any desired direction. The invention is based on the object of providing a low-voltage luminaire of a kind which can be arranged on boards or partitions at any desired point in such a manner that the light cone can be adjusted in any desired direction. The object is solved in that the mounting arrangement of the luminaire consists of two rotary discs which are made of an electrically conductive material, form a hinge and are separated from one another by an insulating disc, the central axis of rotation of the hinge being formed by an axle bolt of an electrically non-conductive material, which is mounted with a specific axial prestress on both sides in bearings of an electrically conductive material, rods of an electrically conductive material, which are connected to a power source and run perpendicularly to the axis of rotation of the hinge, being mounted in these bearings, the other ends of the rods being mounted with frictional adhesion in holes of holding bodies such that they can be rotated freely and displaced axially.

Patent DE-3813174-A1 (DE)
Title: Brake pressure control device
Inventor: VOLZ PETER DR
IPC: B60T8/175
Filed: 1988-04-20
Abstract: A brake pressure control device, especially an antilock control device and traction control device for motor vehicles with a dual-circuit brake system is demonstrated. Each brake circuit is autonomous in that it comprises its own pump (59, 60), driven by electric motor, and that each motor (57, 58) can be individually controlled by the electronic control unit (66), as a result of which precisely metered volumes are delivered into each brake circuit and in the respectively assigned working chamber (63, 81) of the tandem master cylinder (64). With the volumes delivered a controlled positioning is achieved, especially of the pushrod piston (85). In control mode the brake pedal (1) is thereby also positioned by the pushrod piston in a position in front of its starting position. Advantageously, in traction control mode with a division of the two brake circuits for both front and rear axle, only that pump (60) can be started, which supplies the brake operating circuit for the driven axle. <IMAGE>
