Patent DE-4243785-A1 (DE)
Title: Compact control valve for hydraulic servo system
Inventor: LINSER JOERG J PROF DIPL ING
IPC: B62D5/08
Filed: 1992-12-23
Abstract: The valve has a rectangular block (6) moving in a shaped bore between two end settings.

Title: Combination stand for the sport of blowpipe shooting
Inventor: REBBE KLAUS DIPL ING
IPC: F41J3/00
Filed: 1993-03-04
Abstract: In order to ensure that the sequence of the event is well organised, it is essential to develop a stand which, by holding all the game components (blowpipes, arrows, targets), can be used as a combination stand for the completely refined game centre for the sport of blowpipe shooting, with good handling and the necessary safety. The object is achieved in that a two-piece main stand (8, 9) is constructed on supporting feet parts (1, 2, 3) as the holder for the transverse magazine supports (5, 6) for blowpipes (14), arrows (15) and paper targets (16) in the lower part of the main stand (8), and as a holder for the component target (13) and the two cantilever arms (10, 11) which support the mesh (12), in the upper part of the main stand (9). By virtue of its multifunctional construction, the stand is suitable for positioning and game use of all the game components for the sport of blowpipe shooting, for competition and for pure spare-time recreation. <IMAGE>

Title: Method of operating a stud-welding system, and system for it
Inventor: TILLMANN AXEL
IPC: B23K9/20
Filed: 1993-03-09
Abstract: A stud-welding system, consisting of the welding gun with lifting magnet and spring preloading for the stud holder and a control unit, is operated in such a way that the position of the stud holder is indicated to the control unit over the entire working cycle and is compared with a predetermined displacement-time behaviour. The differential signal controls the lifting magnet in such a way that, when the spring is released, the lifting magnet brakes the stud holder while maintaining the predetermined behaviour. When the stud is lifted, the predetermined arc length, despite stud tolerances, can be maintained by means of the position transmitter.

Title: Braking mechanism for magnetic tape video recording - has pivot mounted link with teeth that engage pinion on mode switching gear to control movement of spool
Inventor: KANG MYUNG GOO
IPC: G11B15/22
Filed: 1993-06-17
Abstract: A video camera-recorder receives cassettes loaded onto a pair of spigots. The tape is drawn out of the cassette by a pair of guide rollers moved along tracks until contact is made with a helical scan head drum. Each spool is associated with a tape braking system for retaining the spools in position when not in operation. The wind-up spool (11) is associated with a mode switching gear wheel (30). The integral pinion is engaged by the teeth of a brake element (20) that is a pivot mounted (21) link. The link operates against a torsion spring (24) to effect release. The release is provided by displacement of a pin (23). ADVANTAGE - Prevents magnetic tape from deviating from set path.

Title: Installation pipe made of copper with an inner surface of tin oxide and process for coating same
Inventor: TRIQUET CHRISTIAN DIPL ING
IPC: F16L58/08
Filed: 1993-06-25
Abstract: The invention relates to an installation pipe made of copper with an inner, uniformly adhering surface of tin oxide having a layer thickness of between 0.05  mu m and 0.5  mu m and a diffusion interlayer of copper/tin-alpha-monophase having a layer thickness within the range from 5  mu m to 20  mu m and to a process for coating the installation pipes. The process comprises essentially the steps of chemical tinning of the inner surface of the copper pipe, subsequent diffusion annealing of the copper pipe under inert atmosphere to create a copper/tin-alpha-monophase on the inner surface of the tube, followed by an oxidising thermal inner surface treatment with a gas mixture to create a surface composed of tin oxide. The layer of tin oxide ensures high-grade, consistent and long-term protection against a release of copper ions into the drinking water.

Title: Projection-type television device
Inventor: GLEIM GUENTER DIPL ING
IPC: H04N9/31
Filed: 1993-08-11
Abstract: A projection-type television device contains three monochromatic picture tubes (image tubes) which lie in one plane and each have a deflecting unit which is fed deflecting currents and raster-correcting currents for the vertical and horizontal deflections. In the case, in particular, of novel image tubes which have a curved phosphor screen, enhanced correction is required for all tubes. The object is to provide a simple circuit, in particular for those image tubes having a curved phosphor screen, which permits a smaller correction of the two outer image tubes and has a lower long-term deviation. The correction voltages (UGV, UGH) fed to the middle image tube (G) are also fed to the two outer image tubes (R, B), and additional correction voltages (URVz, URHz; UBVz, UBHz) are fed to the two outer image tubes (R, B). Intended particularly for projection-type television devices having image tubes with a curved phosphor screen. <IMAGE>
Patent DE-4329649-A1 (DE)
Title: Device for the protection of electrical devices of a motor vehicle against putting into operation without authorisation
Inventor: BROICHER HERIBERT F DR
IPC: B60R25/04
Filed: 1993-09-03
Abstract: The invention relates to a device for protective electrical devices of a motor vehicle against putting into operation without authorisation. The object of the invention is to prevent, as far as possible, the unauthorised starting and driving of a motor vehicle with simple means. This object is achieved by an inaccessible circuit arrangement of a relay (or a semiconductor switch), connected upstream of the electric starter or the ignition coil, with a resistor and fuse in the actuating circuit of the relay. The actuating line to the relay is accommodated in two of many cables of a cable harness which ends in an accessible, multipole male strip connector and is covered by a plug. The latter connects the two cables of the actuating circuit. All the other cables are connected, via the fuse of the actuating circuit, to earth. Any attempt to produce the right pole connections on the male strip connector without the plug has a high probability of leading to a short circuit and blocking of the circuit. The circuit of two or more relays in series in each case via the cable harness reduces the probability of unauthorised usage.
