Patent DE-2406076-A1 (DE)
Inventor: FIEUZAL JEAN HENRI
IPC: F16H57/12
Filed: 1974-02-08
Abstract: A reversible-output rotary gear drive device for applying two directional rotation to a turret e.g. a gun turret. The device comprises an output gear adapted to apply rotation to the turret, and two input gears selectively driven in dependence upon the desired direction of rotation of the turret. In order to take up play in the coupling between each input gear, when idle, and the output gear, an intermediate gear is provided in a gap between the input gears and applies biasing torque to each input gear when idle so that a previously idle input gear is always in a state of readiness to transmit drive, without play, to effect rotation of the turret.
Patent DE-2410167-A1 (DE)
Title: Protective pipe sealing ring for cable - hollow section seal is evacuated for easy insertion and vacuum released when in position to give tight seal
Inventor: STEWING ALBERT
IPC: F16L17/10
Filed: 1974-03-02
Abstract: The coupling of thermoplastic pipes, used for the protection of cables, is effected by an elastomer sealing ring which provides a gas and liquid tight seal. Such pipes are of large diameter and require that the coupling is achieved with a minimum effort. One pipe section is of parallel diameter and locates with ample clearance within the bore of a second pipe. This latter pipe has an enlarged section into which a sealing ring is located. The sealing ring is of hollow cross-section and is manufactured with a radial depth greater than the clearance chamber between the pipe. By applying suction to the inner volume of the seal the width is considerably reduced and permits easy insertion into the chamber. Once the pipes are coupled, a hollow needle is inserted through access holes and the vacuum released. The seal expands against the side walls to give a tight sealing effect.

Title: Racemic biotin prodn - by reacting 2,3,8,9-tetradehydro-biotin with triethyl-silane and trifluoroacetic acid
Inventor: SAWYALOW SERGEJ IWANOWITSCH
IPC: C07D495/04
Filed: 1974-04-11
Abstract: Racemic biotin is produced by reacting 2,3,8,9-tetradehydrobiotin (I) with triethylsilane and trifluoroacetic acid (molar ratio (I):SiEt4:CH3COOH pref. 1:2:9-10), pref. at 20-70 degrees C, and separating off the product. Rac. biotin is a highly active growth stimulant for microorganisms and is used in the production of bakers' yeast. Biotin (vitamin H) can also be used as an agent against hypertension, atherosclerosis and skin disorders, as a component of cosmetic agents, and as a biostimulant in animla rearing. Production of racemic biotin by catlytic hydrogenation of (I) over molybdenum sulphide/Al2O3 is known, but yields are low and variable, rendering the procedure unsuitable for use on a technical scale. The new reduction procedure enables purified rac. biotin to be obtained in 8% yield.

Title: Mechanical disc brake wear indicator - has plunger attached to pad and movable axially with it to indicate wear
Inventor: SCHNEIDER WILHELM
IPC: F16D66/02
Filed: 1974-08-09
