Title: Radar and satellite radio wave mode duplexer - has first coaxial line a-ranged in central long axis of main hollow waveguide and second taken through latter's wall
Inventor: SCHUEGRAF EBERHARD DIPL ING
IPC: H01Q25/04
Filed: 1978-01-31
Abstract: Wave mode duplexer, for radar and artificial earth satellite radio, decouples the electric fundamental from the hollow waveguide connected to the base of the aerial. The magnetic fundamental is passed as a data-carrying wave by the hollow waveguide, and the electrical fundamental is brought out of the hollow waveguide for forming deviation data for automatic target follow-up of the direction of max. radiation of the aerial. To enable complete decoupling of the directional carrier wave from the signal wave of any desired polarisation to be realised, a first coaxial line is arranged in the central longitudinal axis of the main hollow waveguide. The inner conductor of the first coaxial line is continued as a capacitive, end-on, rod-shaped probe in the direction to the aerial.

Patent DE-2817654-A1 (DE)
Inventor: ASANO KAZUHIRO
IPC: G04C3/14
Filed: 1978-04-21
Abstract: An electronic timepiece reduces power consumption by normally driving the stepping motor with a short pulse and driving the motor with a wide pulse under heavy load conditions by sensing the rotor position. A detection circuit senses the voltage drop across a detection element in series with the motor coil for driving a first detection pulse and senses again for driving a second detection pulse. If the second voltage drop is larger, then the rotor is not rotating whereupon the wide pulse is used to drive the motor.

Title: Rotary kiln for cement clinkering - has bucket chain to ensure mixing with minimum suspension of dust in furnace gas
Inventor: MARTIN HENRI
IPC: F27B7/16
Filed: 1978-06-29
Abstract: The caloridic exchange between solid material and gas in a rotary kiln for prepn. of cement, is improved by a process including the following steps. (1) a sloping heap of solid material is formed, the slope falling away in the forward direction of rotation during the ascending part of the motion; (2) a certain quantity of material is removed from the region of this slope and carried in the forward direction of motion in the surfaces; (3) this quantity of material is held captive for at least part of the upward motion of the furnace beyond the sloping heap and for part of the descent; (4) the captive material is then released close to the furnace wall during the descending part, from the monomer when the vertical trajecting of the material falling is far enough from centre of the kiln; (5) a second sloping heap of material is then formed in the descending part of the kiln. As well as the improvement in heat exchange, the system avoids putting dust particles into suspension in the gas near the centre of the kiln.

Title: Automatic circuit synchronisation in superheterodyne receiver - uses tuner voltage to balance deviation of difference frequency between main input and auxiliary oscillators
Inventor: HANSEN JENS DIPL ING
IPC: H03J3/28
Filed: 1978-08-04
Abstract: The input circuit with an electronic turner is synchronised with the oscillator circuit (main oscillator) oscillating at a higher frequency than the intermediate frequency. A second, auxiliary oscillator has a tuner identical with those of the input circuit. A difference frequency in the intermediate frequency range is produced from the main oscillator frequency and the auxiliary freqeuncy. Deviation of the difference frequency from the intermediate frequency is balanced outby a control voltage applied to the auxiliary oscillator.

Title: Emergency power supply alarm circuit - monitors flotated battery charge current or discharge current and battery voltage using differential amplifier coupled to AND=gate
Inventor: BECKER KARL
IPC: G01R19/165
Filed: 1979-09-11
Abstract: An emergency switching circuit connects an emergency battery supply when a regular supply fails. The circuitry monitors the load current and provides a switch-over signal if the current fails. Normally, the equipment (3) is powered from a main supply (5) via a reverse current protection diode (5). The main supply (4) also supplies charging current (IL) for the floated battery (1) used to supply power should the main supply (4) fail. Differential amplifier and gate circuitry provides power supply monitor and alarm output conditions. The float battery charging current is monitored by a resistor input differential amplifier (7) which provides a logic '1' output to the AND gate (11) should the current fail. A further differential amplifier (8) monitors the discharge current (IE) from the emergency battery (1) when it is on line, and a further differential amplifier (9) monitors the voltage (UB) of the emergency battery (1) against a reference standard (UV). The AND (11) and OR (12) gates provide alarm output (13) should current or battery voltage fail.
Patent DE-2940271-A1 (DE)
Title: Automatic measurement of telegraphy speed - finding approximate value from probability curve and refining by comparison with signal
Inventor: HISSEN HELMUT DR
IPC: H04L1/20
Filed: 1979-10-04
Abstract: The speed of a telegraphy signal is measured by determining the times between transitions from one level to the other and digitising them. The times are first accumulated in a store to build up a probability distribution and the shortest time with significant probability, e.g. 10%, is taken as the step time. Deviations of transition times from multiples of the step time are then summed - sum A, and the multiples themselves are summed - sum B. During the summation, the signal is tested to exclude interference pulses. The ratio A/B is then added to the step time. This is repeated until A/B changes sign at least twice. The speed is then computed as the reciprocal of the step time. The method can be used for automatic measurement by a computer and is suitable for speeds up to 100kBd.
Patent DE-2945587-A1 (DE)
Title: Control device for NC machine tool - has two types of computers, coupled by data bus, each second type computer generating rated values for each associated drive
Inventor: KIRCHHOFER HEINZ
IPC: G05B19/418
Filed: 1979-11-12
Abstract: A first computer (1) generates acceleration, speed and rated path values in accordance with input dates for the individual scanning intervals, defined by Clock pulses from a clock pulse generator (2). These rated values are supplied over a data bus (3) to various axial calculators (4, 5, 6), each allocated to movement axis. Each such calculator has its output connected to a feed drive (7, 8, 9) for the associated movement axis. Each calculator receives the actual position values for an actual value generator (10, 11, 12). According to the data from the first computer each calculator transmits rated values to the control circuit for the associated drives. This transmission depends on the path to be travelled and on the position values given by the actual value generators. The allocation to the computer operations to the common computer and the axial calculators enables a parallel data processing, which in turn enables high feed velocities, even with several controlled movement axes.
