Patent DE-2443090-A1 (DE)
Title: Flexible ball joint assembly for vehicle steering linkage - has axial cover plate to retain joint assembly inside housing
Inventor: SCHMID LEOPOLD F
IPC: B62D7/10
Filed: 1974-09-09
Abstract: The housing for a ball joint assembly has the form of an open cylinder. A flexible bearing ring with radial lugs is placed in the housing, followed by the ball element and the second bearing ring. A cover plate with a hole for the shaft of the ball element is then wrapped around the undercut flange of the bearing housing. The inner rim of the cover plate is tapered towards the ball such that it restricts the axial movement of the ball shaft. The screw connection on the other end of the housing body carries a tapered clamp ring made from steel. This ring and the cover plate carry the principal loads, thus the housing body can be produced from aluminium.

Title: Safety seat for rear automobile seats - has retracted head rest which automatically raises when seat is occupied
Inventor: PROTZE DIETER
IPC: B60N2/48
Filed: 1974-10-08
Abstract: In order that the drivers view to the rear is least obstructed, the seat cushion is provided with a sensor (7) which responds when the seat is used to actuate a hydraulic, pneumatic, mechanical or an electrical device to raise the head support to the required position. The sensor consists of a flexible container (4) filled with either a liquid or a gas and connected by a tube (5) to a bellows located in the head rest (8). The weight of the occupant displaces the fluid or air in the sensor to cause the bellows to unfold and bring the head rest into the protective position. A spring (7) in the seat cushion reverses the process when the seat is vacated.

Title: Amplitude to phase modulation conversion coefficient - is measured by a corrective feedback network including filters and a demodulator
Inventor: STROBEL HELMUT DIPL ING
IPC: G01R29/06
Filed: 1974-12-20
Abstract: The network is for the improved measurement of the so called amplitude modulation to phase modulation conversion coefficient in amplitude modulated signals under certain circumstances. Two known methods are for measuring this coefficient, which is a measure of the unwanted phase modulation component in an amplitude modulated signals. There is a direct and an indirect method. The new method represents an improvement on both of these and is suitable for coefficients of under 1 degree per dB. One amplitude modulated signal is monitored and mixed (25) with the original generated signal to remove inherent frequency-and phase-modulation, filtered with a bandpass filter (26) and taken to a frequency modulator (27). A further bandpass filter (28) and level measurement circuit (29) produce the required output, which is a measurement of the phase modulation.

Title: Folding leaf door with power-driven thrust element - performs simultaneous rotation and translates flow of force from drive to door leaf
Inventor: KAUFFMANN HANS DIPL ING
IPC: E05F15/605
Filed: 1975-02-25

Title: Solid fuel domestic cooker - has refractory target plate wall separating combustion chamber from smoke box
Inventor: TIETZE ALFRED
IPC: F24B1/10
Filed: 1975-02-27
Abstract: The cooker has a combustion space (1) above a grate (3) with an ash pit (2) below it. The top of the combustion space is formed by the hob (7). There is a smoke box (4) behind the combustion space with a flue outlet connection (5). A little way before the back of the combustion space a target wall plate (6) extends down from the underside of the hob about two thirds of the way towards the grate. It leaves a gap (8) between its lower edge and the grate. Gases given off by the fuel in the front part of the combustion space must pass through this gap which contains burning fuel. This ensures that combustible gases given off by highly volatile fuels are burnt before reaching the smoke box.

Title: Hybrid turbine and paddle wheel - has wheel rotating in vacuum enclosure with peripheral chambers closed by radially extendable elements
Inventor: GULAIF JOSEF
IPC: F03B17/06
Filed: 1975-10-22
Abstract: The wheel is for producing mechanical energy by a combination of three effects. Firstly it is provided with radially extendable elements which act as paddles whilst being immersed in flowing water. The wheel is contained in a vacuum enclosure with a water lock so that the water level inside the enclosure is above that of the flowing water. The buoyancy of these elements, whilst extended, adds to the rotational movement acting on the wheel. Waste steam or hot power stations waste wate is admitted into the chamber below the elements where they are extended. The weight further adds to the buoyancy and thus to the rotational movement. Each element retracts when in the uppermost position and expels the contents of the chamber.
Patent DE-2551642-A1 (DE)
Title: Tugging and pressure eliminator for safety belts - has additional clamp in front of reorientating buckle or rolling up mechanism
Inventor: SZPERKOWSKI REINER G
IPC: B60R22/19
Filed: 1975-11-18
Abstract: The tugging and pressure eliminator is for safety belts with automatic rolling up mechanism. An additional clamp is installed around the belt in front of the reorientating buckle or in front of the rolling up mechanism. This clamp is positioned by its guide diameter which is slightly narrower than the belt. In the manual version (3), the clamp is pushed by hand in front of the reorientating buckle (1) when the normal sitting position is taken up. This prevents any further unwanted unrolling of the belt and any further pressure on the body. Functional movements of the belt are not, however, influenced. In the automatic version the clamp (4) is integrated in a guide sleeve.
