Title: Test machine for rotationally elastic coupling - applies torsional bias via mutual bracing between concentric holders
Inventor: HUECK MANFRED
IPC: G01M13/02
Filed: 1979-09-08
Abstract: The test machine for rotationally elastic couplings, rotational oscillation dampers etc. with primary and secondary components has two rotationally mounted holders to which the test pieces can be attached. One holder has a uniform drive whilst the other is driven periodically varying angular speed. A torsional bias is applicable at low cost, esp. without requiring an electrical generator. The uniformly rotating device is a flywheel (23). The holders have attachments for several, pref. two, test couplings. This enables torsional bias to be generated adjustably in the couplings by mutual bracing. For testing two couplings (10,10') each holder receives the primary section of one coupling and the secondary section of the other. One holder (22) fits approximately concentrically through the other (24). Their bearings rest on a common fixed part.

Title: Connector block with optical indicator element - which is connected across impedance between incoming and outgoing terminals, and in series with current path
Inventor: JAEGERSKUEPPER RAIMUND
IPC: H01R9/26
Filed: 1979-10-04
Abstract: The terminal block, typically of a shape which can be assembled onto a strip with similar blocks by mounting on a rail, is intended to indicate the presence of current flow. The object is to show that a circuit is connected and active. Between the incoming and outgoing terminals (3,4) is an impedance (6) in series with the current path, and an LED (95) is connected across the impedance. In order to limit the voltage drop, and make it effectively independent of current, the impedance is typically a diode, or two diodes in series. The resultant voltage drop, typically between 0.8V and 1.6V, is sufficient to fully illuminate the LED (5). For ac circuits anti-parallel diodes and anti-parallel LEDs can be used. The components are assembled inside an insulated housing forming the terminal block (2).

Title: Brewing vat heating system - using separate circuits for exhaust steam from steam driven compressor and for compressed vat vapours
Inventor: EHMANN GERHARD ING GRAD
IPC: C12C13/02
Filed: 1980-01-03
Abstract: A heating system for brewing house vessels, specially brewing vats, is based on live steam and on vapours, compressed in a vapour compressor. Two separate heating circuits are used for life steam and for the compressed vapours. A steam driven piston compressor or a turbo-compressor is used to compress the vapours. A steam boiler produces superheated steam to drive a steam engine. The exhaust steam reaches a first heating element in a brewing vat and is recycled by pipe to the boiler. A compressor, driven by the engine, compresses the vat vapours and passes them to a second heating element in the brewing vat. The discharge through pipe is used to prepare hot water. This system creates little noise and is functionally reliable. It requires little maintenance and makes the best possible use of the heat contact of the vapours produced in brewing houses.

Patent DE-3113908-A1 (DE)
Title: Hydraulic heating apparatus
Inventor: SANDAU HARTMUT ING GRAD
IPC: G05D23/13
Filed: 1981-04-07
Abstract: The hydraulic heating apparatus has a control valve for holding constant the temperature of a pressure medium delivered by a pump (14), in which there is arranged a pilot valve (34) which is influenced by a temperature-sensitive expansion element (37). The pilot valve controls a valve body (29) which, together with the pilot valve, brings the temperature of the pressure medium to the desired value by means of throttling. In order to switch off the heating apparatus, a bypass line (70) with a cock (71) is provided, which bypass line (70) bypasses the valve body and the pilot valve and opens into the housing (10). From there a channel connection (62, 64) leads to the expansion element (37). If the cock (71) is not fully opened and as a result the pressure medium is warmed, then the expansion element (37) is also correspondingly warmed and now controls a neutral circulation of the pressure medium delivered by the pump, so that no unacceptable temperature increase can occur. <IMAGE>
