Title: Control unit power supply circuit for air-conditioning equipment - has current through resistor varied by shunt control unit responding to temp., etc.
Inventor: THOMA FRITZ
IPC: G05D23/19
Filed: 1977-05-04
Abstract: The power supply, for control devices in air conditioning equipment receiving control signals has a resistor whose value depends on ac or dc current in the two-wire line that supplies power to the electromechanical and/or electronic devices. This resistor is in series and/or parallel with a control device whose resistance can vary between 0 and infinity in response to room temp. and the changes. The current through the resistor can thus be controlled. The current changes are used to control the air conditioning equipment.

Title: Recording process write pulse generation - uses master slave coupled flipflops with comparator output stage to convert phase encoded binary information
Inventor: WIRTH HANS-JUERGEN DIPL ING
IPC: G11B20/14
Filed: 1977-05-21
Abstract: The phase encoding of binary information into write pulses for recording processes is provided by clocked flip-flops operating into a comparator stage. A clock generator (5) produces out of phase signals (51, 52) of the same frequency to enter input signal data (E1) into R-S flip-flops (1, 2) operating in a master-slave mode. An equivalence gate (4) generates an output when the states of the flip-flops are the same. The resulting signal is entered into an output flip-flop (3) by a third phase shifted clock signal of twice the base frequency. the output (A3) is used as a write signal.

Title: Laser weapon, esp. for anti-missile defence - has fusion material extruded as thread into reflecting laser chamber
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/00
Filed: 1977-08-24
Abstract: The parent patent describes a weapons laser for defence against aircraft and rockets and for civilian applications. In this addn., the fusion material is extruded as a thread from a nozzle, after the manner of spinning synthetic plastics threads. The spinning appts. may be heated or cold.

Title: Domestic waste water heat recovery unit - using fan in vent pipe to produce air counterflow for heat exchanger
Inventor: THOREN TORGNY ALEXIS
IPC: F28D21/00
Filed: 1977-09-15
Abstract: The heat energy which is normally discarded in every household with the hot water from baths, washing up etc. is recovered by a fan installed in the already existing vent pipe on every drainage system. Air is admitted downstream in the drain pipe and entrained by the fan past a heat exchanger where the heat is extracted and used to heat fresh water. The drainage system (4) of a private residence (2) is equipped before the cleaning pit (3) or the connection to the main sewer with an air inlet (1). A fan (5) installed in the vent pipe can thus entrain air in counterflow to the discarded water. This warm air flow heats up fresh water in the heat exchanger (6), for a warm water system or space heating. The best thermal efficiency is achieved if the heat exchanger (6) is the evaporator of a heat pump.

Patent DE-2757607-A1 (DE)
Title: Joining glass-fibre-reinforced, laminated, plastics components - by cutting back successive plies to form steps which fit steps cut in opposite laminate end, and lap joining free end of reinforcements
Inventor: ERNST HERBERT ING GRAD
IPC: B29C70/00
Filed: 1977-12-23
Abstract: To achieve a positive connection of (glass-fibre) -reinforced plastics laminated mouldings e.g. containers, pipe sections and fittings, the plies are successively cut back at the edges to be joined to form steps receding as viewed from a butt end of the inner plies. This stepping is effected so that the gaps between abutting ply ends increases in an outward direction. The length of each step is many times that of its weight. Reinforcing plies protruding from the ends of the plies overlap the abutting ends of the inner plies and are embedded in a lamina that fills the steps. Used for securely joining plastics laminated components e.g. tanks contg. corrosive substances, large-dia. pipeline sections. Process is relatively simple. Joints have substantial tensile strength whilst being only negligibly thicker than the components themselves.

Title: Operator request for services in telephone exchange - uses semiconductor array in selecting programme stored in central processor
Inventor: CEZANNE LOTHAR
IPC: H04M3/60
Filed: 1978-06-20
Abstract: Each operator position is connected to the central processor through preprocessing unit. They are scanned cyclically so that, if any of their special keys are pressed, an address passes through the preprocessing unit to the input buffer of the central processor. The computer causes the programme store to add a code to this before sending the total word to the programming array. Here it is converted into a new address, which initiates a programme to realise the required service. Specific services are thus quickly achieved e.g. automatic dialling of programmed numbers, call transfer etc.

Title: Tubular capacitor construction encapsulated in plastics sleeve - has one lead wire through length of tube twice supported and metal cap for second contact lead
IPC: H01G4/28
Filed: 1978-12-21
Abstract: Construction of a tubular capacitor with thin dielectric and of supporting the lead in connecting wires so that they do not flex and damage the dielectric nor require brace supports which increase the construction costs. The lead-in wires make contact with metal layers on either side of the dielectric material. One connecting wire with a nail headed end extends through the body centre of the capacitor to be firmly held in a resin glue which forms a rigid mechanical support between both lead in wires entering either side of the tubular unit. The nail headed lead-in wire also has a bulbous section remote from the nail head, which is soldered to form an electrical connection between it and the inner metallised layer of the dielectric unit. The dias. of both the nail head and the bulbous section are smaller than the dielectric tube so that they fit inside. The second end connection is via a metal cap soldered to the outer metallised layer of the capacitive dielectric.

Title: Overload release circuit for three phase supply - includes extended time integrator with operational amplifier and network for stable switching
Inventor: MEYER HERBERT DR ING
IPC: H02H3/093
Filed: 1979-03-26
Abstract: The overload release circuit for monitoring the three phases of a supply circuit has three parallel rectifiers (10, 11, 12) connected to an adjustable divider (14a, b, c) followed by an extended time integrator (15). This acts as a delay system and includes a resistance/diode network forming a back coupling to give a non linear output. This occurs during the first third of the voltage region so as to give a stable threshold switch, and gives a high temp stability. The integrator has an operational amplifier (16) with a back coupling circuit including two resistances (20a, b) connected to the positive input and another resistance (20d) and a diode (21) at its output, forming two parallel branches. Between the junction of the two resistances and the junction between the diode and third resistance is a bridging resistance (20c). The positive input is also connected (27) forming a release input to which an earth connection can be made, resulting in the non linear output.
