Filed: 1979-07-12
Abstract: The power control system has a device that disables the control unit when the engine is in a given operating state. The control unit interrupts the operation of the piston/cylinder units in accordance with a programme dependent on the position of the accelerator pedal. The throttle flap in the suction line of the engine is fully open when the control unit is functioning but is coupled to the accelerator pedal when the unit is not functioning such that when the pedal's position remains constant the power produced by the engine as a result of the throttle flap is equal to the power produced in response to the control unit.
Patent DE-2929136-A1 (DE)
Inventor: HUEBNER HORST DIPL PHYS DR
IPC: H01J35/10
Filed: 1979-07-19
Abstract: An intermediate layer comprising several sub-layers is sandwiched between the support and a target layer of a rotary X-ray anode. The sub-layer of the intermediate layer which contacts the support and the sub-layer of the intermediate layer which contacts the target layer both consist of pure rhenium. Interposed between these two sub-layers is a further sub-layer consisting of a rhenium alloy containing at least one carbide-forming metal, for example tungsten, tantalum or hafnium. This construction of the intermediate layer provides a barrier against carbon diffusion, which barrier has substantially the heat conduction properties of metals and which offers a sufficient protection against the penetration of carbon into the target layer, even at temperaturers above 1500 K.

Patent DE-3028577-A1 (DE)
Title: Low heat waste IC engine - has mixture of alcohol and water continually injected to increase output
Inventor: LINDEMANN ROLF W
IPC: F01N3/04
Filed: 1980-07-28
Abstract: A mixture of water and alcohol is continuously injected into the cylinders of an i.c. engine. The heat of combustion vaporises the mixture and its expansion adds to the power output of the engine. At the same time the latent heat of vapourisation is drawn directly from the combustion chamber which thus needs less external cooling so that less waste heat is lost to the cooling water or air. If the engine has a turbocharger the injection takes place into the compressor of the turbocharger so that the heat lost from the after cooler is also reduced.
