Title: Shock absorbing friction plate coupling - uses steel ring with radial holes to improve cooling and capacity
Inventor: ABOU-KAMAL SAMY DIPL ING
IPC: F16D13/64
Filed: 1975-11-04
Abstract: The coupling consists of a flat steel ring and two plates which are mounted either side of this ring. Friction pads are mounted on the two plates. The central ring is coupled via springs to a splined hub. The springs take up any shock loading. The coupling is normally engaged as the coupling ring is pressed by a spring disc against the rings with friction pads and the central steel ring. To disengage the coupling, a coupling hub is pressed against the centre section of the spring disc and releases the pressure of this disc against the coupling rings.
Patent DE-2549804-A1 (DE)
Title: Charging airstream with cleaning fluid from tank - is by suction and without turbulence at point near exit port
Inventor: DUEHLMEIER RUDOLF
IPC: B24C7/00
Filed: 1975-11-06
Abstract: The cleaning fluid is held in a mixing tank (11), which is replenished as required from a reservoir above it. It has been usual to introduce the airstream at one side of the tank, so that it can pick up fluid before leaving at the other side. However, this creates a turbulence in the tank, which soon causes wear. In the improved system, the air inlet pipe (6) is brought well across the tank, to a point opposite, and close to, the exit port (9). Fluid will be sucked into the pipe through a hole (7) in its side, near the exit end. The fluid and air will mix in the remaining short length of pipe and the mixture immediately be discharged, straight through the exit port. The tank will thus suffer little wear, and so can be less substantially made.
Patent DE-2557589-A1 (DE)
Title: Air-cooled rotary piston i.c. engine - has magneto laminations which are used as engine balance weights and triangular piston with internally toothed wheel
Inventor: WEEBER HERMANN ING GRAD
IPC: F02B53/00
Filed: 1975-12-20
Abstract: The rotary piston engine has a cylinder with trochoidal surfaces and a triangular piston with curved sides. The piston has an internally toothed wheel which drives an eccentric shaft. To ensure smooth running the engine is fitted with balance weights. Instead of fitting balance weights directly to the engine shaft the magneto laminations (6) are fitted in a housing provided with lugs (4,5) and bolted to the blades (3) to the cooling fan (1). This method eliminates the need for separate balance weights and reduces the total engine weight.

Patent DE-2619434-A1 (DE)
Inventor: FAHRMEIER WALTER
IPC: F21Y103/00
Filed: 1976-05-03
Abstract: The luminaire can be operated with different lamps fitted, without this producing the impression of defectiveness. Specifically, the covers (31, 32), such as louvres, screens or shields, do not cover the entire light exit opening of the housing (1). Held detachably in the latter is at least one insert (2) which carries the lamp holders of the fluorescent tubes (60) and accommodates ballasts and accessories (e.g. starter 63). Each insert has an I-shaped support part (21) which lies in the plane of the said light exit opening and on which adjacent covers are mounted. Such a luminaire with different lamps fitted can thus be used for different required luminous intensities. <IMAGE>
Patent DE-2630470-A1 (DE)
Title: Automatic control for windscreen wipers - uses capacitance monitors and impulse control to differentiate between fine and large raindrops
Inventor: SCHMIDT KARL-HEINZ
IPC: B60S1/08
Filed: 1976-07-07
Abstract: The incidence of moisture on the windscreen is monitored by capacitative monitors and the output signal is used to drive the windscreen wiper control for automatic wiping. The control is fitted with an impulse amplifier to differentiate between large and small raindrops, so that for large drop the wipers are switched on sooner, and at a faster rate. Conventional controls do not differentiate between fine rain and heavy rain but are controlled by the number of drops falling per unit area. The wipers are then operated too soom in fine rain and too late in heavy downpours. The apparatus provides a more realistic response and results in a safer vehicle.

Title: Pipe end closure cap - has tight fitting parallel shoulder preventing fouling of pipe and flared part welded to pipe
Inventor: NACKE WOLFGANG ING GRAD
IPC: F16L55/11
Filed: 1976-07-21
Abstract: The pipe end closing cap allows access to the pipe by sawing off a certain piece of the pipe, without the danger that swarf might enter the pipe. The cap is tapered with a stepped-down taper (14) and bottom (16). The open end has a section (18) which is parallel with the pipe inside wall. This section is followed by and outwardly flared end by which the cap is welded onto the pipe end. If it becomes later necessary to open up the pipe end, the sawing-off is carried out halfway across the parallel section of the cap, so that part of this section still remains fitting closely with the pipe end preventing ingress of impurities into the pipe. The cap then is removed by using pliers on the extrusion (28) on the bottom surface of the cap.

Patent DE-2652635-A1 (DE)
Title: Single phasing protection for three phase motor - uses detection of unbalance in rectified current transformer secondary currents
Inventor: MOEHNLE JOSEF
IPC: H02H7/09
Filed: 1976-11-19
Abstract: The motor (M) has a current transformer (1, 2, 3) in each supply phase (R, S, T). The secondary of these transformers has a rectifier (4, 5, 6) and the rectified currents are arranged to sum to zero when the primary currents are balanced. To achieve this effect one rectifier (5) is in opposition to the other two, and the current transformer ratio is matched to suit. Loss of any phase causes an unbalance in the rectified output and a resulting current flow to trip the protection relay (7) which opens the motor supply circuit breaker. Where current transformers are already installed the circuit can be adapted by using a second set of suitably matched current transformers connected to the secondary side of the existing units.
Patent DE-2653915-A1 (DE)
Title: Emergency lighting readiness monitoring circuit - operates by turning on static inverter and comparing its output voltage with reference
Inventor: BEERMANN DIETER DIPL PHYS DR

Title: Mobile Doppler radar station - has two mixers whose Doppler frequencies are used to determine relative motion of station w.r.t. target
Inventor: LINDNER KURT DIPL ING
IPC: G01S13/62
Filed: 1977-03-31
Abstract: The radar station has a circuit for determination of its relative direction of motion w.r.t. its target. When a self-oscillating mixer stage is used for generation of transmission and Doppler frequencies, a coupling element, e.g. a directional coupler (2) is inserted between the mixer stage and radar antenna. It delivers a part of sender and receiver energy to an additional mixer stage (4), and a phase discriminator (7) derives the direction information from Doppler signals delivered by the main and additional mixer stages. The aerial can be a slot antenna in the form of a rectangular hollow conductor. An additional mixing stage can be coupled to the hollow conductor. The length of the latter can be so selected that the phase discriminator itself determines the direction information.
