Title: Overflow control for model aircraft fuel tank - detects motor load by voltage drop across resistor for comparison with reference voltage
Inventor: MUELLER ECKART
IPC: G01F23/00
Filed: 1979-04-05
Abstract: The overflow control causes the load experienced by the supply pump motor to increase, with this increase detected to cut-off the motor and prvent overflowing. The tank has a ventilation pipe with a throttle restriction at a given height of small dia than the fueld supply line so that when the fueld in the tank reaches this height, the pump pressure increases causing the rise in the motor load. The latter is detected by measuring the voltage of a resistor connected in front of the motor and comparing it with a reference voltage to cut-off the motor circuit when the measured value drops below the reference voltage. Pref. the supply line from the pump includes a magnetic valve opened via a transistor switch when the motor is running.

Title: Digital signal model railway control - uses error detection information word framing to control locomotives and track equipment through track
Inventor: HAASS ADOLF
IPC: A63H19/24
Filed: 1979-04-30
Abstract: The model railway control uses multi-level codes so that the clock pulse is always present and can be used for the error detection. Information pulses coinciding with the clock pulse increase the level. All transmission is via the track and the time division multiplexed signal is structured in frames. Each frame is preceded by and finishes with an alignment word. Between the frame alignment words are three information words which are also five bit structures. The information words are used to address the controlled object and agreement between the first and the last information word ensures the code validity and content of the command so that it is released for use. Error detection is also used by comparing the clock with the code and initiating a valid count pulse.

Title: Selection pulse generator for telephone set - has semiconductor switches performing pulsing and bridging functions
Inventor: WURMITZER ARMIN
IPC: H04M1/31
Filed: 1979-05-03
Abstract: The selection pulse generator uses semiconductor switches to disconnect the loop in synchronism with the selection pulses and also to bridge circuit parts during generation. The semiconductor switches are driven by a controlling circuit consuming relatively little power. During selection, with the loop closed, no voltage drop occurs in the loop and no energy is taken from the voice wires. The semiconductor switches are FETs. The advantage lies in replacing mechanical contacts by semiconductor switches.

Title: Multistage grain drying chamber - uses passing of extracted hot air to common heat pump for return through individual channels
Inventor: PASCHEN ERICH
IPC: F26B21/06
Filed: 1980-04-10
Abstract: The drying chamber for grain etc. has three successive stages, e.g. drum dryers or belt driers (31,32,33), and the heated air is extracted through channels (51,52,53) at each transfer position. The combined air flows are then collected in a common duct (54) and passed through the evaporator coil of a common heat pump (62). The condensate is discharged through an outlet (61), and the air is forced through a heat exchange coil (63) by a fan (56). The heat pump is operated by an engine (65) whose exhaust gases are used to supply further heat to the heat pump circuit. The temperature difference at inlet and outlet is less than for previous drying chambers. The reheated air is returned by different paths to the different drying stages, these paths being parallel to the original hot air paths. An alternative arrangement has the air flowing in the opposite direction to the material flow.
