Title: Hammer drill with rapid chuck changing mechanism - has torque transmitted by balls which can be extracted radially by turning outside locking ring
Inventor: REIBETANZ WILBERT DIPL ING
IPC: B25D17/08
Filed: 1990-03-30
Abstract: The end (8) of the chuck (13) fits into the driving sleeve (4) of the hammer drill. Inside the sleeve and impacting on the drill shank (28) are the strikers (5,6).

Title: Coating float glass with coloured or colourless layers - by spray coating with pref. glassy material
Inventor: GRAEFE LUTZ DIPL ING
IPC: C23C4/00
Filed: 1990-04-26
Abstract: Coating float glass with coloured or colourless decorative glass layers consists of flame spraying with the substrate glass at a temperature at least equal to the softening temperature of the coating particles. Coating can be complete or partial using a pattern plate to produce a decorative effect. The sprayed coating may be glassy, partially crystalline or crystalline, while, colourless or coloured, transparent, semi-opaque or opaque. The coating thickness is pref. 0.1-0.5 mm. Different colourations can be achieved by varying the thickness and/or mixing or overlapping colours.

Title: Open=end rotor spinning unit - has auxiliary equipment at the output producing yarn with a soft handle suitable for knitting machinery
Inventor: BROCKMANNS KARL-JOSEF DR ING
IPC: D01H4/40
Filed: 1990-12-13
Abstract: Unit produces yarn with real twist which is drawn off through a spiral bore passage and then via a deflector into a false-twist unit. The yarn is held in a roller pair on the way to winding at the creel. In this manner the loose ends of fibres on the surface of the yarn are prised outwards. Pref. the spinning unit produces yarns with real twist in the rotor. This is extracted via a ceramic conical funnel device with a spirally formed interior along the yarn passage and retaining a real twist. A further device is implemented which has deflector pins first in one direction and then the other. At this stage some form of bent tube is applied and leading to the false-twist unit. This is a pneumatic device to twist the yarn surface in the opposite direction. The twist may also be applied in the same direction to produce yarn with an increased twist with the advantage of a higher speed of output. ADVANTAGE - Prodn. of yarn from an OE rotor is given a softer handle, suitable for knitting machines.

Title: Hybrid vehicle comprising electric motor car with removable power trailer - carrying IC engine operating generator for direct propulsion, via buffered battery of towing vehicle's electric motors
Inventor: LOBE HARTWIG
IPC: B60K6/46
Filed: 1991-06-28
Abstract: The electric motor car without its power trailer has an autonomous range in the town traffic up to 100km. The electric motors connected to the vehicle's battery propel the motor vehicle's wheels. The battery can be recharged during stops from sockets in the parking places (usually during the night). Analogous to a Diesel-electric engine, the i.c. engine powers the generator and its current, via the battery, drives the motors. In the coupled condition the i.c. engine is controlled by the driver from the passenger space. It can also be operated by an automatic charging regulator to control the recharging of the vehicle's battery and the additional battery which are interchangeable. The power trailer is equipped with a high speed coupling system which allows a quick coupling of the trailer's power when the hybrid vehicle needs to increase its speed over a certain limit and with an automatic trailer steering assembly which facilitates the reverse running. The reserve wheel, the tools and an additional luggage space are also on the power trailer so that the wt. of the electric motor car is minimised and the passenger room maximised. ADVANTAGE - Combines advantages of clear i.c. engine vehicle with advantages of electric drive.

Inventor: LANG ARMIN
IPC: B62D5/087
Filed: 1991-08-06
Abstract: In a servo-assisted steering system, in particular for motor vehicles, a pinion (2) mounted in a steering gear case (1) engages a rack. A steering valve (14) for regulating the hydraulic medium for the servo-assisted steering system has two inlet seat valves (15, 16) and two outlet seat valves (17, 18) whose closure bodies (20, 21, 35, 35) can be moved in the axial direction by the rotation of a steering column. The closure bodies (20, 21) of the inlet seat valves (15, 16) can be biased in the closing direction by the force of pressure springs (22, 23) which engage the closure bodies (20 ,21) of the inlet seat valves (15, 16) only when the corresponding outlet seat valves (17, 18) are in their neutral position. In the neutral position of the steering valve (14), each pressure spring (22, 23) maintains the closure body (20, 21) of the corresponding inlet seat valve (15, 16) pressed against a valve seat (26, 27) permanently fixed to the case. When the steering valve (14) leaves its neutral position, one of the outlet seat valves (17, 18) lifts the pressure spring (22, 23) of the corresponding inlet seat valve (15, 16) above the disk (24. 25) of the closure body (20, 21) of the inlet seat valve (15, 16).
