Title: Circuit arrangement for limiting overvoltages
Inventor: WOLFF HERBERT
IPC: H02H9/04
Filed: 1984-01-24
Abstract: In order to limit overvoltages on an apparatus having two power supply lines, a controllable switch is provided in one of the two power supply lines, and a comparator, whose output is connected to the control input of the controllable switch, whose first input is connected via a constant voltage source to the output of the controllable switch, and whose second input is connected to the other power supply line. In the event of overvoltages, the switch which is controlled by the comparator isolates the connected apparatus from the operating voltage. If the controllable switch is constructed as a transistor, the switching-on current surge in the event of a high capacitive load resulting from the connected apparatus can additionally be reduced by means of a capacitor, via the control junction of said transistor.

Title: Heat pipe for thermally conditioning, in particular cooling a liquid contained in a vessel
Inventor: BAEHRLE FRIEDRICH
IPC: F01M5/00
Filed: 1984-07-07
Abstract: The invention relates to a heat pipe for thermally conditioning, in particular cooling liquid, such as can be applied chiefly for an oil-lubricated unit having oil cooling, in particular in a motor vehicle. The heat pipe extends through the wall of the unit housing and is arranged in the oil sump of the unit housing with its heat-absorbing part; at its heat-dissipating part, it is flowed around by ambient air which is conveyed by a fan. This fan, which can be designed as an axial or radial fan, is provided with air guidance which surrounds the heat-dissipating part of the heat pipe around the same axis, and can be switched on and off by a thermostatic switch which can be controlled by a temperature sensor and responds to the temperature on the heat-absorbing part of the heat pipe. The heat pipe is expediently produced from an aluminium extruded profile with a double wall and axially extending distance ribs therebetween in such a way that the cooling air flow of the fan can be guided into the interspace of the double wall. As regards application, the invention is particularly suitable for oil-lubricated gears such as differential gears and speed-changing gears with a high thermal loading. For the purpose of heating the liquid, the air guidance can be provided with heating wires to which electricity can be applied.

Title: High-resolution optical length-measuring method using a coded absolute scale for carrying out the method
Inventor: TRUMPOLD HARRY PROF DR ING
IPC: G01B11/02
Filed: 1984-07-23
Abstract: High-resolution optical length-measuring method using a coded absolute scale for carrying out the method, preferably for the purpose of absolute displacement measurement and positioning in general machine building and instrument manufacture, in particular under the conditions of automated production. The aim of the invention is to provide a method and device for absolute length measurement which permit a higher resolution in conjunction at the same time with lesser demands on the scale. This is achieved when a serially coded absolute scale on which a bar code is provided in the measuring direction between the scale marks is scanned in the measuring direction by an optoelectronic line sensor and this information is further processed by a logic circuit to yield the measurement result. This method is also used for angular measurement.

Patent DE-3438112-A1 (DE)
Title: Hydraulic power amplifier
Inventor: HAYN HOLGER VON
IPC: B60T13/16
Filed: 1984-10-18
Abstract: The invention starts from a hydraulic power amplifier (1), in particular for activating a main cylinder (3) in motor-vehicle brake systems, in which an amplifier piston (15) can be displaced in the actuating direction by admission of pressure. The actuating pressure can be set by a brake valve (29, 30, 31) which can be activated hydraulically, the brake valve being hydraulically operable. A corresponding activating pressure is obtained by a relative displacement between the amplifier piston (15) and the piston rod (22). With regard to a substantial simplification in the construction and minimisation of the sealing friction, it is proposed to integrate the brake valve (29, 30, 31) in the amplifier piston (15). <IMAGE>

Title: Heating device
Inventor: KANTNER ALESANDER DR RER NAT
IPC: F24H4/04
Filed: 1985-02-28
Abstract: In heating devices with at least one boiler part and a storage part, there are frequently difficulties in the case of retrofitting and new installations. In terms of erection, compromises must be struck. In terms of circuits and lines, installation errors cannot be excluded. To avoid these shortcomings, at least the boiler part and the storage part, and if appropriate also the heat-pump part additionally, are now in each case integrated separately in housings in a building-block or modular manner, which can then be arranged next to and/or above one another. In the housing walls, punchings are preprogrammed, via which the hydraulic and electric lines are guided, which interconnect the individual modules.

Abstract: PCT No. PCT/DE86/00117 Sec. 371 Date Nov. 19, 1986 Sec. 102(e) Date Nov. 19, 1986 PCT Filed Mar. 19, 1986 PCT Pub. No. WO86/05511 PCT Pub. Date Sep. 25, 1986.The present invention concerns a process for secondary purification and stabilization of liquids containing polyphenols and/or proteins. The liquid to be treated is first subjected to a centrifuge, or similar apparatus, which performs the primary purification of the liquid. The treated liquid is then mixed with stabilizing means that adsorb the polyphenols and proteins and filter means that retain the fine turbidities contained within the liquid. The liquid mixture is then transferred to an alluvial filter apparatus in laminar flow wherein the filter means and stabilization means along with the adsorbed polyphenols and proteins form a filter cake. The purified liquid is then transported to subsequent treatment while the filter cake is subsequently treated with a solution which dissolves the polyphenols and protein thereby regenerating the stabilization means and the filter means.
