Title: Centrally-controlled telephone PBX - stores line-group address of wanted line in queue store for comparison with released lines
Inventor: GRAF GOTTFRIED ING GRAD
IPC: H04Q3/62
Filed: 1978-02-27
Abstract: The telephone private branch exchange allocates lines using existing storage devices and depending on the conditions of lines in groups of lines. The addresses of groups of lines in which a free line is wanted is stored in a queue store. When a line becomes free this fact is signalled to the operator and line reservation initiated which leads to the operator connecting his set to the free line. Checks are periodically performed to find lines that have become free. When a free line is found within any group the contents of the store are compared with the waiting requirements in the queue store.

Title: Continuous weigher with automatic calibration - has regularly repeated, logic-controlled check weighing sequence (NL 4.12.78)
Inventor: WHITEFORD SCOTT CUNNINGHAM
IPC: G01G11/00
Filed: 1978-05-31
Abstract: The continuous weigher comprises a conveyor by which individual items may be placed on the weighing scale. An electromechanical transducer providers a signal which is converted to digital form for displaying the weight. When a predetermined number of items have been successively weighed, a control logic unit initiates a calibration sequence. A calibration weight is placed on the weighing platform after the tare weight has been recorded. The two values are compared in a comparator and the difference registered. If the difference is not greater than +- 2% the conveyor is restored to nromal operation. If a greater difference is detected and a correction applied and a calibration lamp comes on. The weigher is checked once again by the same sequence and if the difference is within +- 1 g the normal operation is restored.

Title: Liquid filter with belt medium - having feed and take=up rolls mounted above and below the filter box with buffer zone between feed roll and filter box
Inventor: MILLER PETER ANTHONY
IPC: B01D29/00
Filed: 1978-07-26
Abstract: Liq. filter used a movable belt as medium held between a feed roll and a take-up roll. The belt itself is clamped under a filter box with an evacuated box below this. The belt can be moved in either direction to discharge the cake and move it round into a wash zone. Between the feed roller and the filter box there is a buffer zone consisting of a series of rollers round which the belt passes. As the belt is moved backwards and forwards to clean it, this zone prevents soiled belt from being rewound onto the feed roller. Used for filtering liqs. in the chemical, pharmaceutical, food, drink, sugar and metallurgical industries. The system prevents blinding of the cloth due to particles being pressed into its rear surface when wound up.

Title: Signal processing circuit for IR gas analysers - has switch controlled by phase shifter, so that only specified signal reaches display device
Inventor: SCHAEFER WERNER DIPL PHYS DR R
IPC: G01N21/37
Filed: 1978-10-16
Abstract: The infra-red analysers have a radiation modulator and a two-layer receiver as radiation detector, connected to a difference pressure gauge with a diaphragm capacitor, whose signal is a measure for the concentration of the measured component. Synchronous auxiliary signal pulses derived from the modulator (4) are applied through a phase shifter (2) to a switch (1) between the diaphragm capacitor (8) and the display device (11). The switch (1) is controlled by the phase shifter so that only the capacitor signal component reaches the display device, which is shifted by 90 deg. to the residual signal when the measured component is absent in the gas.

Title: Synthetic plastics pipe with external undulating surface - is extruded and pierced by reciprocating die maintaining cylindrical interior
Inventor: MIKI SHINJI
IPC: B29C48/10
Filed: 1979-04-18
Abstract: The die head of an extruder has a fixed and a periodically reciprocating section between which a moulding chamber is formed. Plastics pipes are produced esp. for irrigating and drainage purposes, which have alternately thick, radially outwards projecting circumferential zones, and flexible, thin-walled circumferential zones, extending along the length of the pipes. A large number of perforations is provided in the thin-walled zones. In these zones also, the wall circumference may be curved radially inwards to improve the flexibility of the pipe, which internally is near enough cylindrical. After precooling and calibrating the pipe is drawn by profiled rollers and is axially compressed before reeling. The pipe is fully capable of withstanding all normal loading and it cannot become silted up by matter washed out of the earth.

Title: Telephone subscriber's line circuit - has earth key detection with increased resistance if key is held too long
Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q1/38
Filed: 1979-05-07
Abstract: A subscriber's line (b, a) is connected via the hybrid transformer (U) to a resistive transmission ridge consisting of a capacitor (C) shunted by a resistor (Rh) and two resistors (Rb, Ra) connected to ground and battery (-UB) respectively. Operation of the subscriber's earth key is detected by an operational amplifier (V) with its input across the capacitor and its output compared with a threshold (UtHl) by a second op-amp (K). If teh subscriber holds this key down too long, a contact (po) opens to put a high resistance (Ri) in series with the battery supply to the line. For test, the contact can be opened with the earth key not operated. Output from the detector then indicates faulty line insulation. If line insulation appears O.K., a lower threshold (Uth2) can then be used to check that the contact (po) is operating correctly.

Title: Sea water desalination - by atomisation of solar preheated sea water in ascending natural draught and condensn.
Inventor: TUREK KLAUS DR
IPC: C02F1/14
Filed: 1979-06-01
Abstract: Desalination plant consists of a shaft in which an ascending carrier air stream picks up evaporated sea water from atomisers in an evapn. space. In a condensn. space above it, a heat exchanger receives cold sea water and causes the water vapour to condense. The cold sea water then passess through a solar heat collector before it is atomised in the ascending air stream, produced by natural draught. The reduced consumption of electrical and/or prim. energy makes this process more profitable. The plant is simple and can be mfd. at low cost, yet it meets all functional requirements.
Patent DE-2924729-A1 (DE)
Title: Protection circuit for static inverter in converter - has protective thyristor bridging outputs of mains rectifier and turning on when volts on commutating capacitors exceed limit
Inventor: LANDECK WOLFGANG DIPL ING
IPC: H02H7/12
Filed: 1979-06-16
Abstract: The protection circuit has one or more thyristors (V3) bridging the outputs of the converter's mains rectifier (V1). The gate of the thyristor is connected to a device (E) that produces turn-on pulses when an inadmissibly high voltage appears at the commutating capacitors (C1-C5) between the ac connections of the static inverter. A current limiting resistor (R) is in series with the thyristor. The turn-on pulses for the controlled mains rectifier and for the static inverter (V2) are generated at the same time as the turn-on pulses for the protective thyristor. A fault is indicated when the protective thyristor is turned on and the composite converter is disabled.
