Patent DE-2530545-A1 (DE)
Title: Vehicle gear box with synchronizing friction rings - has locking segments to ensure synchronization prior to gear engagement
Inventor: ERNST ROLF
IPC: F16H37/04
Filed: 1975-07-09
Abstract: The vehicle gear box has a synchronization system which includes tapered friction rings (30) and a slider ring assembly (10). The friction rings are joined by axial bolts (31) such that the gap between the rings locates locking segments and spherical steel balls. To couple two gear wheels of unequal rotational speed, the slider ring is moved axially in either direction so that one of the two friction rings engages the appropriate tapered collar of a gear wheel. When the speed is synchronized, the slider ring is able to complete its movement, thus the two gear wheels can be brought in mesh with each other without difficulty. At that stage, the locking spheres are displaced against radial compression springs.
Patent DE-2532592-A1 (DE)
Title: Tape recorder tape tension regulation unit - uses tape tension scanner for deflection of guide roller
Inventor: ARWEILER OTTO
IPC: G11B15/43
Filed: 1975-07-21
Abstract: A tape recorder tape tension regulating unit uses a scanner for scanning the tape tension between two tape reels. Dependant on the tension of the scanned tape, a deflection of the guide roller is produced which increases or decreases the braking or tensioning effect on the tape. Forces exercised as a result of the tape tension are converted to a signal which controls the torque of a reel motor or brake. The evaluated component of deflections of the guide roller (15) is at right angles to a straight line which results from the connecting line of the end points of diagonals starting form the diversion point.
Patent DE-2537172-A1 (DE)
Title: Wheel set guide for rail vehicles - has flexible connection elements with adjustable spring characteristics provided by conical sliding sleeve
Inventor: KAYSERLING ULRICH DIPL ING
IPC: B61F5/32
Filed: 1975-08-21
Abstract: The wheel set guide is for high-speed running of rail vehicles. Each wheel set axle is carried on either side in bearings in housings retained height-adjustably by guide elements, relative to the running gear frame, and supported via spring units. A flexible connection element is positioned between one end of the guide element, and the neighbouring section. The flexible connection element (4) has an associated pressure element (13) actuated by an energy carrier (14), and which adjusts the spring characteristics of that element. A return unit (12) acts in a direction (16) opposite to that (15) of the pressure element, to reduce the tension in the elastic sleeve (6).

Title: Matrix for calibrating used cartridge sleeves - has ram for removing the sleeve from matrix body without damaging sleeve
Inventor: WEIGEL WOLFGANG DR ING
IPC: B21D51/54
Filed: 1975-08-26
Abstract: The matrix body (1) is made from a hardening steel. The body is usually made from rod material. The calibrating bore (3) is made to suit the various standards of cartridge sizes. The nominal bore of the calibrating matrix is usually made 1% smaller than the standard size to allow for elastic deformation of the sleeve, which is forced into the bore. A push-out rod (2) is mounted in a hole which is concentric with the calibrating bore. The push rod has a slide fit in this hole. The diameter fo the push rod is made so that it corresponds with the inside diameter of the cartridge sleeve after calibrating. A key slot (5) is provided in the push rod into which a grub screw (4) protrudes.

Title: Emergency sliding supports for levitated vehicle - have spring and damper system reducing impact when skids meet track
Inventor: GUENTHER CHRISTIAN DIPL ING DR
IPC: B61B13/08
Filed: 1975-10-02
Abstract: The levitated track system has emergency supports which contact the track when the magnetic levitation system fails. The emergency supports in the form of skids are suspended to ensure physically minimum force of the contact impact. The spring and damper system combinations installed between each emergency support and vehicle are specified. The spring force is constant from the point of time of contact with the track to reaching the max spring deflection. The necessary characteristic for spring displacement is ensured for linear spring characteristic by a damper with square characteristic. The optimum maximum force is then twice the min force max. value when no damping is used.

Title: Fuse protection mechanism against hatch opening - has spring-loaded levelling member thrusting locking teeth against guide rail
Inventor: HARDT WALTER
IPC: E06B9/86
Filed: 1975-12-05
Abstract: The mechanism protects fuses against the inadvertent raising of the armour of a roller hatch composed of hollow profiled bars, there being locking devices extending at right angles to the armour surface from the heads of the bars and engaging with the flange of a U-section guide rail. The fuse securing devices are fixed by strips to the respective hatch bars. A movable levelling member (12) in the uppermost bar (3) exerts on the locking teeth a pressure with the aid of a spring etc. via the uppermost pivot point (10) of the lever (5) connecting the safety devices of the bar (2), so as to thrust the teeth (7) against the guide rail (4).
Patent DE-2556932-A1 (DE)
Title: Magnetic coil system for plasma fusion power generators - uses symmetry to prevent large destructive magnetic forces when one supply fails
Inventor: GRIEGER GUENTER DR
IPC: H01F7/20
Filed: 1975-12-17
Abstract: The magnetic coil system is for Tokomaks and Stellarators and other related plasma-physics equipment requiring large magnetic fields. It consists of separate coils supplied from two or more supplies and arranged so that all those coils connected to a given supply are essentially symmetrical with respect to the coil system as a whole. The advantage of this symmetry lies in avoiding the destructively large magnetic forces (c. 6x106 Newtons) that can be generated if one half or part of the supply fails. The supports for the coil assemblies do not therefore need to be so massive and expensive.

Title: Self service exit swing door with panic safety mechanism - has closer locking bolt connected for movability outside notching range
Inventor: ERTLE KARL ING GRAD
IPC: E06B11/08

Abstract: The swing-door is esp. suitable as a barrier in a self-service store passage. A rotatably mounted door frame, on a floor-anchored upright tube, can be swung back into its exit setting by the swivelling lever of a door-closer fixed in the tube, and it is fitted with a panic safety mechanism mounted in the tube. The locking bolt (16) sited in the door-closer (8) is force-lock connected, pref. by a screw bolt (15) with a rotatable setting knob (14) at the top end of the tube (3), so that it can move outside its normal notching positions. The setting knob is positioned so as to be friction-locked against the socket (19). It is possible to vary the swivelling characteristic of the door-closer to any extent desired, after the door has been put into operation, easily and without assembly work involved.
