Title: Pacemaker electrode with dome-shaped wire-claws at front end - uses remotely-operated piston to open claws when correctly located
Inventor: KARR DIETER E DIPL PHYS
IPC: A61N1/05
Filed: 1979-08-01
Abstract: An undesired, premature attachment of the electrode to the heart tissue is avoided by the use of two claws which form a smooth, pointed dome-shaped front end when closed, until it has reached its desired location. A piston is then operated remotely to open the claws and effect secure attachment. The electrode comprises a hollow metal cylinder (1) with a supply lead (2) and a connector (3). A non-conducting piston (4) is moved forward when the electrode is in situ by pushing a wire which runs inside the hollow connecting cable, at its far end. This opens the two or more claw shaped wires allowing attachment of the electrode. The same arrangement permits withdrawal of the electrode.

Title: Automatic supervision of call information in multifrequency form - by comparing total signal length against reference values represented by six tone signals
Inventor: EISLE ENGELBERT
IPC: H04M3/24
Filed: 1979-09-17
Abstract: The application related to electronic telephone exchanges in which a microprocessor controls the number selection and call routing functions. The routing and other call supervisory information is transmitted by multifrequency code pulses generated, for example, by two out of six tone generators (SE1,...SE6). This tone signal is transmitted to the line (L) through a transducer (U). The amplified tone signal level is measured in a loading resistor (R3), and a proportional signal processed and applied to a supervisory element (Tr). An error resulting in an incorrect proportional signal level is signalled to the processor (P) by the supervisory element (Tr) and a predetermined error routine put into operation. The system requires no response by the call receiving end exchange.

Title: Operating method for turbocharged engines - has dwell of valves timed to give better torque characteristic
Inventor: PAPEZ STANISLAV DIPL ING
IPC: F02B29/08
Filed: 1979-10-19
Abstract: The invention is a method of operating exhaust turbocharged internal combustion engines. It uses known methods of altering the dwell time of the inlet and exhaust valves with engine speed so as to match the engine and turbocharger requirements. This method of operation overcomes the disadvantages of the low torque produced by turbocharged engines at low speeds and results in a more advantageous torque-speed characteristic. It is also possible to alter the timing of the valves to overcome any restriction due to overheating.
Patent DE-2942746-A1 (DE)
Title: Small power plant for rivers and streams - is anchored and has wide inlets to receive surface layer of flow which is deflected by baffles
Inventor: ROHM ERNST
IPC: F03B13/10
Filed: 1979-10-23
Abstract: The small floating power plant is anchored in streams and rivers and has a relatively wide inlet opening for the active top layer of the water stream. During the flow the stream velocity is braked, resulting in the release of an energy which can be converted into electric current. Inside the inlet opening a baffle diverts the water flow in such manner that it reaches at neutralised velocity the impeller region. The cross sectional surface of the flow channel from the inlet opening tapers in the direction of the impeller position, with the incorporation of central conical bodies. Then it opens up to the original cross sectional surface at the outlet. With the braked speed of the impeller the kinetic weight of the closed water column has an optimal effect under pressure and suction conditions on the impeller blades, providing continuous work force for energy.

Title: Stabilising circuit for HV power supply in photocopier - employs blocking oscillator with corona current dependent regulation
Inventor: THIEL EGON DR
IPC: G03G15/02
Filed: 1979-12-10
Abstract: The switching transistor (T1) in the primary winding circuit of the transducer (W) is in series with a limiting resistor (R2). Its base is connected to the transducer feedback winding through a light emitting diode (D2) which is in optical contact with a light sensitive auxiliary transistor (T2). The transistor has its collector connected to the base of the switching transistor (T1), and is in parallel with the base-emitter circuit of the latter. An increase in base current flowing through the LED (D2), due to an increase in corona current, causes higher light emission. The coupled transistor (T2) becomes more conducting thereby tending to turn off the switching transistor (T1) and thus reduce the corona current. The stabilisation is achieved with few components. It brings with it an improvement in reproduction quality.
Patent DE-3000865-A1 (DE)
Title: Clothes dryer - has heat exchanger before heater to increase efficiency
Inventor: SCHWERDHOEFER HANS JOACHIM
IPC: D06F58/20
Filed: 1980-01-11
Abstract: The heat exchanger is located in the air feed stream in front of the heater, where the hot damp exhaust air also flows through. The system reduces the drying time of the clothes drier, by increasing the efficiency, through maintenance or reduction of the heating capacity. The heat exchanger is placed between the fan and the heater, and it includes a collector for condensation and a mesh to catch lint in the exhaust air flow. The heat exchanger is integrated into one unit with the heater, and is connected to the fan, and carries the drive motor for the clothes dryer.

Title: Coin-operated counter unit - has mechanical counter operated by coins acting against levers coupled to ratchet and pawl
Inventor: VOGEL MANFRED
IPC: G07F5/20
Filed: 1980-01-24
Abstract: A coin operated unit is designed to be triggered by a number of different denomination coins operating on preset lever mechanisms. The insertion of coins produces a change in the value displayed on a number of counter wheels (30), mounted on a common shaft. Each coin denomination is intended to operate a lever (50-52) to trigger a specific display wheel. The trigger levers are in contact with a pawl (43-45) that operates against a ratchet wheel (6). Every time a coin of the correct denomination is inserted, the weight causes operation of the pawl and the number is registered.

Title: Measuring high direct voltages in gas isolated systems - using fixed measurement chamber electrode and ionisation of gas
Inventor: PEIER DIRK DR ING
IPC: G01R15/16
Filed: 1980-07-09
Abstract: An arrangement for measuring d.c. voltages is for h.v. equipment with pressurised gas insulation consisting of a compressed gas container, e.g. a pipe (1) connected to earth potential and contg. a coaxial h.v. conductor (2). The arrangement eliminates the need for moving and has sensitive and not maintainence-free electrode systems. A measurement chamber (3) can exchange gas with the pipe (1) via an aperture (4) and contains a measurement electrode (5). The insulation gas is ionised partially by a source radiating either from inside or outside the measurement chamber (3). This results in a current flowing when a voltage is applied between the h.v. conductor and the measurement electrode. The measurement current to h.v. characteristic can be linearised by selecting the aperture and/or electrode geometry and/or the degree of ionisation.
