Patent DE-2515694-A1 (DE)
Title: Electrohydraulic transmission for small vehicle - with battery driven hydraulic pump and regenerative braking by dynamo and battery
Inventor: FISCHER GERHARD
IPC: B60K17/12
Filed: 1975-04-10
Abstract: The electro-hydraulic vehicle has a battery which drives a hydraulic pump. This pumps fluid from a reservoir to the front-and rear axle mounted hydraulic motors to provide an emission free transmission. The battery is charged by a dynamo, especially when the vehicle is braked regeneratively. The system can be used on two wheel vehicles, as well as four wheel types. It can also be used for boats. The system does not use any fossil fuel, and does not pollute the environment.

Title: Roll driving spindle for rolling mills - USING GEAR .H AND BALL RING SEAT MADE OF AN ELASTIC HIGH STRENGTH PLASTIC
Inventor: NEHL HEINRICH
IPC: B21B35/14
Filed: 1975-05-13
Abstract: Articulated spindle for linking the rolls in a rolling mill with the roll driving pinions, where the two spindle heads are fitted with hypoid teeth meshing with corresp. internal teeth in two bushes, one bush being mounted on the roll journal whereas the other bush is fixed on the journal of the driving pinion.

Patent DE-2538226-A1 (DE)
Title: Elastic throttle valve for hydrostatic shaft bearing - regulates two bearing oil supplies in proportionally opposite volumes
Inventor: WALTER LOTHAR
IPC: F16C32/06
Filed: 1975-08-28
Abstract: A hydrostatic bearing has a bearing shell (9) with a number of separate opposite fluid chambers (16-19). The pressurised bearing oil enters two opposing fluid chambers (16, 18) through a common throttle valve (1) such that th oil pressure in each chamber is equal. If one of the two fluid chambers is subjected to an increased oil pressure due to external shaft loading, its supply path through the throttle valve is expanded, thus more oil is supplied. Since the throttle valve is made from an elastic material, the supply hole for the second fluid chamber is compressed. The oil supply to this chamber is therefore reduced, hence the pressure drops and the shaft tends to return to its central position.
Patent DE-2540941-A1 (DE)
Title: Patient operated spine stretcher - has open frame with straps and belts for limbs and pulley gearing operated by patient
IPC: A61H1/02
Filed: 1975-09-13
Abstract: To work on the lumbar spine, the patient lies within the U-frame (2, 3, 9) on rollers or a sliding cushion and fastens the chest and hip belts (16). The chest belt connects directly with the U-frame and the hip belt over three long straps (13, 14, 15) equally spaced round it, to a cross member which slides along the frame. The patient pulls on the cords (36), moving the sliding cross-member (10) and exerting the required amount of tension on his lumbar spine. The cords pass round a pulley (11) which works through gearing (39) to tigthen a rope (12) and compress a spring whose other end moves the cross-member (10). The amount of the spring compression is shown on a tension meter (38).

Title: Thin walled precision tube - made of metal powder by hot isostatic press forming inside autoclave in sheet metal mould
Inventor: SEILSTORFER HELMUT
IPC: B22F7/08
Filed: 1975-12-12
Abstract: Thin walled tubular precision parts for use as hydraulic pipes, centrifuge tubes or rocket combustion chambers, are prepd. by filling the metal powder into a welded hollow cylindrical mould. This is consolidated by hot isostatic pressure in an autoclave. Part of the mould (inner wall) can be left on the final article. Several different concentric powder layers can also be applied. The pref. material for the mould is austenitic or low-alloy steel, Ni or a Ni alloy. The pref. metal powder is a maraging steel. If the metal powder consists of a beta Ti alloy, the mould can be made of pure Ti, Al or an Al alloy. This reduces any mechanical machining operations to a minimum, also the consumption of material. Delivery times for such articles can be shortened considerably because mfr. does not depend on a barrel forge or extrusion plant. The process is ideal for small batch or one-off prodn. and development times of prototypes can be shortened.
