Title: Remote controlled gear changer - has spring loaded sliding spur gears to ensure rapid gear teeth engagement
Inventor: BORGSCHULTE FRITZ
IPC: F16H63/30
Filed: 1975-09-13
Abstract: A remote controled gear has pairs of spur gears (23-26) which are brought in mesh by relative axial movement. A screw spindle, operated by an electric drive motor produces the axial movement that is required for a gear change. The operating fork (2) applies its linear motion through two sets of compression springs (5). The spring loaded axially sliding gear wheel will thus become engaged with the opposite spur gear at a very high speed. This rapid gear engagement protects the gear teeth, since in some cases a torque is transmitted as soon as the gear wheels start to be in mesh.

Title: Continuous extrusion of thermoplastics tube - with constrictions and diverging regions in relatively short extruder head
Inventor: OPRACH ERICH
IPC: B29C48/09
Filed: 1976-03-16
Abstract: Continuously extrusion of tubes or other hollow sections of thermoplastics is carried out with internal and external cooling of the extruded tube accompanied by calibration as soon as it leaves the extruder nozzle. Material entering the extruder head, immediately it has left the radial distribution zone, is first compressed, then partially mixed then again compressed and then reaches the parallel cylindrical extrusion nozzle. It is then again recompressed shortly before leaving the nozzle and finally leaves in a parallel cylindrical path. Material then immediately enters the cooling and calibrating zone, where it is simultaneously cooled on its inner and outer faces. A relatively short extruder head can be used, thus increasing the output rate. The dimensional accuracy of the resultant tube is improved, thus simplifying the equipment in the extrusion head. The internal and external simultaneous cooling results in a completely stress-free tube. The final calibration is improved on both sides.

Title: High torque spiral spring - is wound in several parallel sections of partial width separated by discs
Inventor: ROEHRS WERNER DR
IPC: F16F3/04
Filed: 1976-09-17
Abstract: A spiral spring for use as spring motor for greater torques than those required for clocks and watches, made of flat strip metal, is so designed that the excessive stresses along the edges, produced by the winding around the spring which causes an outward curvature, are eliminated and the life of the spring is prolonged. This has been achieved by subdividing the spring width b into 2, 3, or 4 parallel sections. Before they are wound up on the core (2), they can be given a slight curvature. To prevent turn-to-turn friction in operation, the sections can be kept separate by discs (1).
