Patent DE-2820821-A1 (DE)
Title: Stepper motor direction meter - with pulses from motor applied to logic circuit and pulse counter with memory
Inventor: LAU WALDEMAR
IPC: H03M1/00
Filed: 1978-05-12
Abstract: A device determines the direction of rotation of a motor, esp. of a stepper motor which is used for raising and lowering the control rods of nuclear reactors, from the arrival of pulses from the winding voltage pickup of the motor. The pulses are applied to a logic circuit which feeds its output pulses to a bidirectional pulse counter and to a direction-of-rotation memory which switches the counter to the 'up' or 'down' counting mode. This device requires only simple appts. to that a functional reliability is ensured. The digital diaplay results in more accurate control of the rods.

Title: Measuring particle concn. of suspension - attaching microphone to impacted tube to detect attenuation of characteristic frequency amplitude
Inventor: RUMMEL THEODOR PROF DR
IPC: G01N9/00
Filed: 1978-06-26
Abstract: The system measures the particle concn. of a suspension passing through a measurement tube (2). A hammer (6) controlled by electromagnet (10) strikes the tube which vibrates at its characteristic frequency. The oscillation amplitude is recorded by a microphone (12) attached to the other side of the tube. The signal is sampled at two lines using a tine base (18). A divider (16) delivers the quotient of the two amplitudes to an analyser (20). The damping characteristic thus determined reflects the suspension concn. and is independent of the suspension flow rate.

Title: Control circuit for setting functions in tape recorder - has master level controller fading and signal in and out, and includes transistor switching
Inventor: PLENER HELMUT
IPC: G11B15/02
Filed: 1979-03-27
Abstract: The tape recorder control circuit has a master level controller (on/off fade control), for fading in and out an audio signal, and a stop controler for stopping and starting the tape. The master level controller is coupled to control logic such that the tape is stopped after the audio signal has been faded out and simultaneously a pretape signal is passed to the monitor output. The level controller operates a pause contact in its end position after the audio signal has been faced out. The pause contact causes the control logic to disconnect the level controller's earthing. The control logic opens a transistor switch between the level controller and earth.

Title: Combined cycle hybrid IC engine - has hot air driven rotary piston, exhaust gas turbine and steam turbine on common rotor discs
Inventor: ECKERT REINHARD
IPC: F01K23/02
Filed: 1979-09-01
Abstract: The hybrid combustion engine combines three separate thermal cycles, i.e. compression, heating and expansion of air, expansion of combustion gases, and expansion of steam produced by heating water. Intake air passes through an axial-flow compressor and from there into a four-stroke rotary piston unit where it produces power after heating by heat exchange with a burner chamber. The exhaust gas from the chamber drives a turbine and heats water in a heat-exchanger. Part of the pre-compressed air passes through a centrifugal compressor and then moves the heated water into a steam chamber in heat exchange with the burner chamber. The steam drives a turbine. The compressor, exhaust turbine and steam turbine stages are combined on common rotor discs.
