Title: Oil distributor valve for supplying two machines - has pressure relief valve by means of which two outlets are alternately supplied
Inventor: GELB HERMANN
IPC: F16N25/02
Filed: 1978-10-07
Abstract: In an oil distributor valve (1), delivery pressure from the main inlet (21a) forces the servo spool (6) to one end of its cylinder (3), thus opening a passageway (9) and admitting pressure to the reversing spool (7). Through further passageways (11, 25), pressure then passes to the end of the control spool and one outlet (31). Above a certain pressure, a relief valve (29) in the main inlet (21a) opens, the spool positions alter, and oil passes instead to the second outlet (32). Shortly after, the pressure falls, the relief valve (29) closes and thus an alternating distribution is established.

Title: Insulated container for electrical modules - made by cold pressing from PTFE coated aluminium sheet
Inventor: KLEMM WOLFGANG WILHELM
IPC: H01G4/224
Filed: 1978-10-17
Abstract: A cup-shaped container for electrical components is produced by a deep drawing cold press operation from a sheet of aluminium which is coated on the inside with an insulating material, capable of being deformed. The pref. material is PTFE which is applied as an adhesive coating to the aluminium sheet at a thickness to suit the dielectric requirements. The cold press operation results in a good molecular bond between the two materials, the PTFE is compressed and receives a smooth surface and a good adhesion. In the case of capacitor housings, PTFE is specially suitable because it combines good dielectric properties with good thermal properties even at higher temps. and with resistance to impregnation oils. The new method therefore creates a simple and low-cost method of enclosing electrical components.

Title: Switching regulator current supply with voltage regulator - uses threshold voltage switching of control pulse FET switch w.r.t supply level, preventing overshoot
Inventor: OESTREICHER WERNER
IPC: H02M3/156
Filed: 1979-01-30
Abstract: A switching regulator current supply contg. a voltage regulator with a desired voltage source, e.g. for supplying a low voltage direct current load from an alternating current supply network, eliminates output voltage overshoot without entailing an unacceptably slow voltage rise time. One voltage regulator (IC2) input (ni) is connected to a capacitor (C3) and via one or more resistors (R8, R7, R5) to the desired voltage source connection actuating the regulator. The same input (ni) is also connected via a switch (T1), pref. a field-effect transistor (FET) to a voltage source whose voltage blocks or opens the control pulse channel (ST). A component (IC1) constituting a control element of the switching regulator holds the FET switch (T1) open as long as the current supply input voltage lies below the desired voltage value. The capacitor (C3) charging circuit time constant is larger than that of the discharge circuit.

Patent DE-2921036-A1 (DE)
Title: Plastic pipe installation - in bends by heating material crosslinked by chemical reaction or irradiation
Inventor: KUNZE DIETER DIPL ING
IPC: B29C53/08
Filed: 1979-05-23
Abstract: Plastic pipes for interior installations, for example water, waste water or hot water pipes have often to be laid in curves or bends. The plastic material of the pipes is exposed to a chemical reaction or to high-energy radiation to change them to a crosslinked structure. In that state, they can be easily made flexible enough to be bent, by applying a stream of hot air. They can receive the required shape without distortion and are then allowed to cool and to set. This saves having to use pipe bends and joints and does not damage the pipes. Mistakes can be easily corrected subsequently.

Patent DE-2940078-A1 (DE)
Title: Automatic gain control of signal amplifier - employing optically sensitive feedback resistors and voltage proportional light source
Inventor: DITTMANN KARL-HEINZ
IPC: H03G3/20
Filed: 1979-10-03
Abstract: A typical application is to the detection and amplification of the output of crankshaft position transducer on a motor vehicle engine. Due to the wide speed range the output voltage of the position transducer varies over a corresponding range, and must be controlled to give satisfactory results. In the proposed circuit the transducer output (Ue) is applied to the input of an operational amplifier (2). The feedback resistors (R2,R4) are connected to a potential divider and are optically sensitive. A proportion (R6,R7) of the amplifier output (Ua) is applied to a second amplifier circuit (4,5,7) connected as a peak voltage detector. Its output controls a transistor (6) regulating the voltage applied to a light source (3) linked with the feedback resistors. At low signal voltages (Ue) the feedback resistance is high giving high gain for the first amplifier (2). As the input voltage increases so the current through the light emitter also rises causing the feedback resistance, and hence the amplifier (2) gain, to fall in order to keep the output voltage constant.
