Patent DE-3245234-A1 (DE)
Title: Arrangement for the starting of combustion engines in flight
Inventor: HUNDHAMMER THEO
IPC: F02N7/00
Filed: 1982-12-07
Abstract: The invention is intended to permit very easy, reliable starting of combustion engines in flight. In the case of powered gliders in particular, electrical starters are too unreliable and above all too heavy. The "pushing" to higher speeds needed to start the engine cannot always be expected of the pilot and is dangerous close to the ground. For this reason a gear is fitted between air screw and engine, which by means of overriding clutches arranged in opposite directions in two secondary transmissions, automatically assigns two different transmission ratios to the differing operating states of starting and cruising. Thus the air screw continues to turn the engine even in slow flight without the need to operate the air screw at incorrect speed when cruising.
Patent DE-3245942-A1 (DE)
Title: Counter-flow deflection sifter
Inventor: CLEMEN HANS-DIETER DR
IPC: B07B9/02
Filed: 1982-12-11
Abstract: The sifting or classifying of fine-grained materials in a counterflow deflection sifter can present very great problems in particular if the fine-grained material is very damp. In such a case, the fine-grained damp material must be previously dried in a separate dryer before it can be charged into a counter-flow deflection sifter for sifting or classifying. According to the invention, this difficulty is eliminated in a simple manner by connecting at least one hot gas feed line (4) to the flow channel (1) in the lower region. <IMAGE>

Patent DE-3303041-A1 (DE)
Title: Automatic steady rest
Inventor: ALLERT KLAUS
IPC: B24B41/06
Filed: 1983-01-29
Abstract: The invention relates to an automatically actuated steady rest for supporting a round body, in particular a shaft, on machine tools, in particular external cylindrical grinding machines, with two or three steady-rest shoes. The steady rest is characterised in that two or three slides are displaceably guided in guide bores in a housing, the displacement movements of the slides are synchronised by connecting members in engagement with them, the steady-rest shoes are arranged on pivotably mounted steady-rest arms frictionally connected to the allocated slides via coupling members, and one of the slides can be driven by means of a threaded spindle by a controllable servomotor. The steady rest guarantees high repetitive accuracy. The movement of the steady-rest shoes takes place uniformly.
Patent DE-3303350-A1 (DE)
Title: Control device for the charging pressure of an internal combustion engine with turbo charger
Inventor: BONITZ JOERG DIPL ING
IPC: F02B37/12
Filed: 1983-02-02
Abstract: A control device for the charging pressure of an internal combustion engine with turbo charger is proposed, it being possible to lower the charging pressure as a function of the signals of at least one knocking sensor (28, 29). As a function of the parameters of load (GP) and speed of rotation (n), the charging pressure (pL) is set via a control device (23, 21). This adjustment takes place electronically, in particular via a charging pressure characteristic diagram which is stored in a memory (40, 41). In order to lower the charging pressure when knocking signals occur, the output signal of a knocking control stage (52) is preferably used for the ignition of the internal combustion engine in order to achieve a simple design of the electronic device. By means of the exact electronic adjustment of the charging pressure, in addition to optimising the operational data of the internal combustion engine (consumption, power, exhaust gas), knocking is largely avoided right from the outset.

Title: Device for potential-isolating transmission of direct and pulse currents
Inventor: ROLLE SVEN ING GRAD
IPC: H03F3/393
Filed: 1983-03-16
Abstract: In a potential-isolating transmission of direct and pulse currents, it is also intended to transmit direct current of any duration and being rapidly variable in time, particularly having a steep-edged curve. This is achieved by the fact that the input current (i) is supplied or removed via the centre tap of the primary winding (w1) of a transformer, the first end (E1) of the primary winding is connected to the drain electrode of a first FET(T1) and to the gate electrode of a second FET(2), the second end (E2) of the primary winding is connected to the drain electrode of the second FET(T2) and the gate electrode of the first FET(T1), the input current is removed or supplied via the connected source electrodes of the two FETs and the output current (iA) is picked up either between the centre tap of the secondary winding (w2) and the outputs of the winding ends connected together after insertion of one rectifier element each (D1, D2), or from a rectifier bridge in the diagonal of which the secondary winding (w2) is located. The invention finds special application in the transmission of (continuous) starting pulses for power semiconductors and in the current transmission for monitoring and measuring. <IMAGE>

Title: Circuit for controlling the rapid-heating mode of electrical car-seat heaters
Inventor: RUTHENBERG BODO
IPC: G05D23/24
Filed: 1983-08-13
Abstract: A circuit is proposed having a rapid-heating control loop and a normal-mode control loop, the control loops having NTC thermistors or PTC thermistors allocated to them as sensor elements. When it is brought into use, the rapid-heating control loop is initially blocked by a timer and a check is carried out to determine whether the temperature acting on the sensor of the rapid-heating control loop warrants the said control loop being brought into use. If this is the case, the rapid-heating control loop supplies a control signal both to switching means for supplying an increased heating current to a heating element in the car-seat heater, and a control signal for controlling switching means which maintain the connection to the voltage source irrespective of the condition of the normal-mode control loop. In consequence, a simplification of the method of operation and a simplification of the circuit construction are achieved.
