Patent DE-2847450-A1 (DE)
Title: Coaxial cable mfg. machine - synchronises mould injection for spacers and uses standard internal conductor length as reference
Inventor: MASLEK PETER ING GRAD
IPC: G01B11/14
Filed: 1978-11-02
Abstract: A coaxial cable mfg. machine has a circuit that monitors the synchronisation of the injection equipment used in the moulding of the spacer discs around the inner conductor. It picks up any synchronisation faults and initiate an immediate correction. The thermoplastic material is injected into a number of moulds along a stretch of internal conductor which is then moved along when the spacer disc has been hardened. A standard length of internal conductor is connected in parallel to the internal conductor on the machine. The length is bounded by two electronic converts which pick up pulses from the corresponding passing discs. There is a circuit which measures any time difference between the pulses and uses it as a control signal for the synchronisation.

Title: Electrical tool with dust-removing fan - has fan motor switched by both triac and by tools main switch
Inventor: MENGE EBERHARD ING GRAD
IPC: H02P1/24
Filed: 1978-11-02
Abstract: The electrical tool has the primary winding (8) of a transformer (9) connected into its circuit.

Title: Car key and lock warming device - has slotted coaxial tube with opening for key attachable to lighter
Inventor: HOELTER HEINZ ING GRAD
IPC: E05B17/00
Filed: 1979-02-07
Abstract: The ddvice for defreezing car door locks during winter periods is attachable to a pocket cigarette lighter. It consists of a conical tube assembly with an external cone (3) and a coaxial internal cone (9) provided with perforations (10). Both tubes are mounted on a common body designed for clipping-on to a cigarette lighter (6). The external cone serves as a protection to prevent touching the hot internal cone. The cooling effect is provided by the air circulating along the gap between inner and outer cones. Both cones are provided with slots coinciding in lateral directions to allow insertion of the car door key to be warmed-up prior to use in the lock. At the same time the tip of flame (8) can be directed towards the lock (2) to accelerate thawing.

Inventor: MERGES VEIT
IPC: F24D17/00
Filed: 1979-02-27
Abstract: The solar heating system, which supplies hot water to a storage tank (20), includes a flow path which by-passes the tank in cold weather, to prevent freezing. this path consists of the discharge line (21) from the heat collector panel (22), with branches (31, 32) to a control valve (V4), then to a warm air heat exchanger (33) above the tank, and back to the inlet line (26) to the panel. The tank is supplied cyclically with hot water, forming layers at different temperatures through a supply line (34), terminating in a section (37) between control valves (V1 V3), at the entry point. A tube (42) immersed in the tank delivers water from low level for further heating. Hot water drawn off by a branch line (38), downstream of the other control valves (V1, V3), is replaced by cold water through a branch line (27) at the top of the tank.

The insulating material is in the form of a cylinder which is open at both ends and is held tightly to the inside of the outer aluminium cylinder. It is made of a solid dielectric material. The dielectric insulator (4) extends axially over both the primary (7) and the after-burning (8) zones of the reactor. This provides heat conduction back to the primary zone to aid in establishing combustion.
Patent DE-2933372-A1 (DE)
Title: Air extract control for rear of car - has elastic flaps to close grille if negative pressure in car
Inventor: GROSSMANN HOLGER DIPL ING
IPC: B60H1/24
Filed: 1979-08-17
Abstract: The air extract control for the rear of a car has the extract ducts fitted with elastic flaps to close the extract if the pressure inside the car is below the outside pressure. This prevents ingress of duct and fumes from the rear of the car. The negative pressure can result from having windows or roof flap slightly open, causing a suction effect, or by running an air conditioning system, with only a limited amount of make up air to supplement oxygen use. At high speeds the negative pressure behind the car can suck air through unprotected rear slots. The elastic flaps provide a simple low cost valving control.

Title: Adjustable towing coupling for tractor - has pair of vertical flanges with hole array to locate coupling jaw
Inventor: MAHLER HEINRICH DIPL ING
IPC: B60D1/42
Filed: 1980-02-26
Abstract: The tractor adjustable towing coupling has the coupling jaw securing to two upright flanges (6,7) by a pair of metal rods (15,17). The jaw mounting has corresponding flanges to align with the fixed flanges from one side so that a lateral alignment is possible, to suit offset loads. To stabilise the coupling jaw laterally the bottom bar is withdrawn and the coupling swung up about the upper bar (17). A lateral movement of the jaw allows it to be dropped back alongside the fixed flanges, with the bottom part of the mounting straddling the flanges and preventing lateral movement. The bottom bar is then replaced. The coupling can then be used for normal road work.

Title: Wind-driven power plant - has resistance surface pivoting about point through 180 degrees, which can be limited to 90 degrees by resilient side stops
Inventor: HOELSCHER HEINRICH
IPC: F03D3/06
Filed: 1980-07-30
Abstract: The power plant is fitted both with a horizontal and a vertical centre shaft. The resistance surface has a pivotal point arranged so that the surface tends to rotate in the wind direction. During each half revolution of the centre shaft the resistance surface rotates through 180 deg. In order to limit its rotation to 90 deg., sprung members are mounted on either side of the resistance surface. The members can be of any arbitrary construction, but of such a design as to permit the resistance surface to rotate through 180 deg. at to high wind force. Pref. the smaller part of the resistance surface is located next to the pivotal point and is balanced into an equilibrium when the centre shaft, or the pivotal point, are horizontal.

Title: Self locking ram with rotary piston - has piston thrusting spiral threaded shaft into similarly threaded hub
IPC: F15B15/08
Filed: 1980-09-08
Abstract: The self-locking hydraulic, or pneumatic, ram has a rotary piston, used to actuate a stopcock, or on a drilling truck in a mining machine. The piston (6) thrusts a threaded shaft (7,20) into a threaded hub, causing the shaft (18) to turn by means of the spiral threads (19). The rotary movement is self-locking by action of a driving spindle (17). The Pitch of the threads can be selected to give this effect. The threaded hub (8) can be fixed to a housing (5) inside the ram cylinder.

Title: Manufacturing procedure for wound capacitor - includes soldering looped ends of conductor wires and injecting insulation into tube ends
Inventor: EHRENBERGER FRITZ
IPC: H01G4/245
Filed: 1980-09-11
Abstract: The capacitor with a winding made from a conductive layer on a wider dielectric layer with connecting tabs projecting from opposite ends of the coil, is enclosed by an outer tube projecting beyond the winding. This leaves a space each end for the coiled end of the conductor wire and a plastics sealing plug. The end of the wire is formed into a loop so that it may be soldered to the bent over outer end of the tab. After the soldering operation, a hot melt plastics material is sprayed intermittently into the two open ends of the outer tube to form the two plugs. After hardening these ends are melted and then smoothed over.
