Title: Two=stage starter for IC engine - has starting screw engaging gear at reduced torque, with full torque supplied from shunt-wound DC motor
Inventor: PFEIFER WOLFGANG DIPL ING
IPC: F02N11/08
Filed: 1978-10-09
Abstract: The two-stage starter has the current supplied to the starter motor during the first stage passing via a current limiter -- which may be an extra winding or a resistor. During the second stage, the starter motor's excitation winding is connected directly via the contact bridge of the relay (that also controls the engagement of the screw) directly to the positive pole of the vehicle's battery. As soon as the second stage is begun, the current limiter's circuit is automatically disabled. The relay can be chosen independently of the current limiter. The current limiter (17) is located in a current path (19) bridging the contacts (6) of the relay (7) between the excitation winding (4) and the positive pole of the battery (10). The current limiter is switched by the start switch (20).
Patent DE-2852306-A1 (DE)
Inventor: LUEF HEINZ
IPC: E05B35/12
Filed: 1978-12-02
Abstract: In order to prevent the possibility of sensing the magnetic coding of a magnetic lock, a detent (13) acting on one side on the blocking element (6, 7) in the direction of the bolt movement is provided in the chamber (12). In the blocking position, the blocking element (6, 7) bears against the detent (13). As a result of the free displaceability of the blocking element (6) into the locking chamber (12) in the open position, the rotors (3) are released. These rotate by mutual influence into a neutral position which does not correspond to the coded release position. <IMAGE>

Title: Remote AC supply to repeater station with safety circuit - transmits test signals to loads in parallel, with measurement across additional choke winding
Inventor: GANZER ERICH DIPL ING
IPC: H04B3/44
Filed: 1979-01-15
Abstract: The remote alternating current supply system for repeater stations in communication networks, is intended to protect service personnel from shock, as a result of any fault. The supply provides alternating current to groups of consuming instruments via supply cables from a common source. Any faulty connections between two supply cable cores triggers an alarm and, in the case of a short circuit, disconnects supply automatically, as in 2853425. A test signal is transmitted along the two supply cable cores and is then measured. The two cores are linked at the transmission end. One choke (21) coil (2a) in the supply line is provided with an additional winding (21d). Both the signal generator and the measuring instruments for the test signal are connected to the additional winding.

Title: Disconnection control circuit for e.g. motor vehicle - has mechanism to disconnect secondary units from generator and other drives to save energy
Inventor: OSSNER ANTON
IPC: B60K25/02
Filed: 1979-06-22

Title: Oxygenation of liquids for biological treatments - using fresh oxygen feed with vent gas purge controlled by pressure and oxygen content in space above liquid
Inventor: BURKEL WOLFGANG DR ING
IPC: C02F3/00
Filed: 1979-06-29
Abstract: Oxygen enrichment of liq. in a closed vessel is carried out by injecting pure O2 into the gas space. The gas above the liq. is drawn into the liq. by means of an agitator. Purge gas is vented. The quantity of gas as fresh O2 injected into the system is controlled by the pressure and O2 content of the gas above the liq. The purge gas exhaust stream is also controlled by a combination of these parameters. The gas input can also be linked with the O2 content of the liq. For use on activated sludge treatment of effluent streams. Improves the O2 utilisation and thus reduces overall O2 usage.

Title: Subscriber's relocating circuit for telephone exchange - blocks subscriber line and reroutes calls initiated by subscriber through temporarily installed exchange terminal appts.
Inventor: VOIGT WOLFGANG
IPC: H04M3/487
Filed: 1980-01-12
Abstract: The additional circuit can be applied where, e.g. a subscriber is moving house but the actual removal date cannot be accurately determined beforehand. The circuit (B), which can be plugged in at the exchange, comprises a receiver unit (E), a comparator (AW) and a memory (SP). The memory contains a single predetermined number. The circuit output controls relay coils (X,U) which operate change over contacts between the subscriber line (TAL), the exchange side (LW) of the line, and a special service (CN). The subscriber connection functions normally with the circuit installed. When the subscriber decides that his line should now be blocked for future incoming calls he dialls the preset number. This selection is detected (AW) and the relays energised to connect the exchange side of the subscriber line (LW) to the special service (SN). Any caller then hears a recorded message, e.g. the new number to call.

Title: Electrolytic recovery of zinc and manganese from soln. - by two=stage process in which manganese di:oxide is recovered before zinc electrowinning (ZA 28.5.80)
Inventor: VERBAAN BERNARD
IPC: C25C1/16
Filed: 1980-04-16
Abstract: Zinc and manganese are recovered from a soln. contg. 25 g/l sulphuric acid and derived from dissolution of Zn and Mn values using recycle electrolyte, by (a) electrolysing (part of) the purified soln., heated to >=70 degrees C, to produce battery grade MnO2 at the anode and Zn at the cathode and (b) feeding the electrolyte, contg. 75g/l H2SO4, from step (a) to the main Zn electrowinning circuit together with any soln. not subjected to step (a). The process is controlled so that the amt. of MnO2 recovered in step (a) together with that plated out in step (b) and lost in any other way is equal to the amt. of Mn added to the soln. during the reuse of spent electrolyte in dissolving Zn and Mn.
Patent DE-3015114-A1 (DE)
Title: Ancillary for circuit telephone subscriber - has nine-transistor circuit powered by A-B lines, for re-directing call
Inventor: SCHOBERTH REINHOLD ING GRAD
IPC: H04M1/00
Filed: 1980-04-19
Abstract: By means of a double pole change-over switch the subscriber may transfer his a-b lines from the telephone set to a fully automatic responder unit which receives power over diodes and which initially passes through two transistors. A zener diode provides stabilised power to an amplifier which waits to receive a ringing tone via a transformer coil, its load being an analogue analyser circuit adapted to recognise a ringing tone as distinct from any other noise to bias a further transistor and which in turn makes the NPN transistor provided for the dialling function conductive. This action charges a capacitor to supply stabilised power to a call code generator. The same begins to produce a preset call number. Due to the holding transistor becoming conductive, the dialling transistor remains conductive until interrupted by dial pulses in the usual manner whereas the initiating transistor ceases to conduct thus keeping current consumption low. Certain supplementary relays are also required in the subscriber related equipment of the central exchange to carry out the thus performed call redirection.
