Title: Absorption heat pump for heating system - has heating circuit split into parallel lines taking up heat from absorber and condenser
Inventor: KAMPFENKEL OTTOMAR DIPL ING
IPC: F25B30/04
Filed: 1979-11-26
Abstract: The absorption heat pump installation comprises a heated (6) pressure vessel (9) containing an aqueous solution (10) of e.g. ammonia, a condenser (20), an expansion valve (23), an evaporator (24), and an absorber (39). A heat exchanger circuit contains radiators (43). The heating circuit splits into parallel lines (48,49) with the relative flow proportions controlled by a three-way valve (46). These two flows take up heat from the absorber and from the condenser. The position of this valve may be controlled by a temp. sensor (55) downstream of the confluence of the lines (49,48) from the condenser and the absorber or by a temperature or a pressure sensor at the outlet end of the condenser.

Title: Rotary machine shaft mechanical seal - has non-rotating sliding ring working against seat ring sealed to shaft
Inventor: INOUE HIROSHI
IPC: F16J15/34
Filed: 1979-12-14
Abstract: A non-rotating sliding ring (4) and a seat ring (3) have sealing faces (5) working together, shutting off the inner fluid (10) outside a holder from an outer one (11) inside it. The seat ring is fixed and hermetically sealed to the shaft (2). The holder moves in the axial direction, being prevented from turning about the shaft axis by a spring (7) and a stop (8). The spring normally thrusts it against the seat ring, to r provide the necessary sealing force when the outer fluid pressure is greater than the inner fluid pressure. The holder is accommodated in a housing (1), sliding axially depending on the pressure difference. Sealing O-rings (13,14,9) are fitted between it and the housing and also between it and the non-rotating ring (4).

Title: Furniture wooden scallop type handle mfr. - involves cutting end faces and grip surface in wood first cut to general shape
Inventor: LAUTENSCHLAEGER JUN KARL
IPC: A47B95/02
Filed: 1979-12-19
Abstract: Shaving work on wood is involved in prodn. of elongated, non-rotation-symmetrical handle fittings for furniture. The handle fittings are of the scallop type and they have a shell piece or grip stem piece engageable from behind. An elongated piece of wood is cut to shape over its whole length, as regards the outside lengthways profile required. The end faces and gripping surface are then cut in or on it. In cutting the lengthways profile, the edge of the shell or grip stem to be engaged by the user's fingers may be cut open, with rounded transitional area. This provides a visually pleasing edge over the whole length of the grip surface.

This ensures that no streaks of fluid are left for the next copy and provides a simple, low cost scraper. The extrusion is ground to remove moulding marks as well as trapped air bubbles near the surface of the plastic. The grinding is done in two directions as a feed speed which provides a polished finish. The grinding wheel is diamond coated, or has a small grit size to produce a polished finish.

Title: Spinning-twisting spindle - has a profiled yarn carrier surface to give vibration to improve fibre arrangement and density
Inventor: KARTMANN SIEGFRIED
IPC: D01H7/18
Filed: 1980-01-10
Abstract: The upper surfaces of the yarn carrier, on the spinning/ twisting spindle assembly, run out from the upper end face of the cen-ral cylindrical body to a highest point. From here, they fall outwards so that the highest point of the upper surfaces of the yarn carrier lies between the central body and the other side or edge of the yarn carrier. As the yarn vibrates lightly during spinning/twisting, with an unchanged tension, the fibre arrangement and density are improved, leading to a more consistent twisting.

Title: Auxiliary brake lights for motor vehicle - are located inside passenger compartment near rear window
Inventor: LIEDTKE FRIEDER
IPC: B60Q1/30
Filed: 1980-05-07
Abstract: The proposed location for the auxiliary brake lights is intended to ensure better visibility for following drivers other than the one immediately behind.

Title: Electronic 1 from 10 code counter - has flip=flop pulse circuit with flip=flop transistors in intermediate spaces
Inventor: MERKLE PAUL
IPC: H03K23/54
Filed: 1980-06-09
Abstract: The flip-flop pulse circuit of the electronic counter operating in 1-from-10 code is designed so that transistors are connected in the intermediate regions between the flip-flops. These transistors are actuated from the count outputs of the flip-flops. Alternately, in special designs, these transistors are actuated by the resetting outputs of the flip-flops, with the counter circuit design being appropriately adapted. Each decade of the counter consists of 10 flip-flops. In operation the active range of the flip-flop circuit is extended by 1 flip-flop. The display takes place over AND-circuits with a negating input. All flip-flops are of identical design and consist of transistors, resistors, diodes and capacitors. The overall resetting of the counter circuit takes place via transistors, while the derivation of transfer pulses, also appearing during overall resetting, takes place via transistors.
Patent DE-3023056-A1 (DE)
Title: Output capacitor discharge circuit for power supply - has variable bias one transistor causing discharge rate to be inversely proportional to capacitor voltage
Inventor: BAILEY PAUL E
IPC: G05F1/618
Filed: 1980-06-20
Abstract: The capacitor is discharged through a transistor connected as a negative resistance device so that the current through it increases as the voltage across the capacitor decreases. The transistor is biased to cut-off while the output voltage is being regulated at the selected value, but the bias is removed so as to permit the transistor to conduct and discharge the capacitor under certain conditions, such as (1) when the voltage is programmed downward; (2) when an overvoltage condition exists; or (3) when the line voltage to which the power supply is connected fails or is turned off. In the latter situation, a capacitor supplies operating power to the circuit for a long enough time to permit it to fully discharge the capacitor. The time during which the transistor is permitted to conduct is limited so as to permit more current to flow without damaging the transistor and thus discharge the capacitor more quickly.
