Patent DE-2253289-A1 (DE)
Title: Oxy-gas burner positioner device - allows accurate location and locking in position by operation of single lever
Inventor: ROEDER GEORG
IPC: B23K7/10
Filed: 1972-10-31
Abstract: The burner is mounted on a shaft which works in between sets of rollers. A side projection on this shaft carries a tube that slides inside a larger tube fastened to the housing in which the main shaft slides. The end of the inner tube is longitudinally slotted and is tapered inside to accommodate a rod which fits inside it and is similarly tapered. This rod is spring loaded so that it tapered end squeezes out the slotted end of the inner tube to clamp it to the outer tube, thereby locking this and the burner in position. The bottom end of the tapered shaft is connected to a cranked handle which is mounted in a tube that has the same diameter as the inner tube, the ends of which meet over an inclined surface. Turning this handle through 30 degrees withdraws the rod to free the inner tube from the casing, allowing its parallel burners mounting shaft to be moved on its rollers. Releasing the handle allows the spring to push the conical ended rod back up the tube to lock it once more in position. The operation of finely positioning the burner is greatly simplified since only the one handle is used.

Patent DE-2356587-A1 (DE)
Title: Roller bearing with eccentric roller cage - produces pumping effect for forced lubricating oil circulation in either direction
Inventor: HENNING ALBERT
IPC: F16C33/46
Filed: 1973-11-13
Abstract: Distance pieces which together with two end rings form the roller cage, are located eccentrically around the inner roller race. The free space around the rollers is sealed off by two seal rings outside each end of the roller cage. Holes on opposite sides of the outer bearing race give access to two chambers in the housing bore which are connected with the supply and return oil line. When the bearing rotates, the eccentric roller cage produces a pumping effect thus forcing oil to flow through the bearing. The effect is the same in both rotational directions. It is thus possible to use the bearing as oil pump for conventional bearings.

Title: Stepless variable ratio epicyclic gear drive - has groups of planet gears transmitting drive from sun input gear
Inventor: BUERGEL WERNER
IPC: F16H3/76
Filed: 1974-02-25
Abstract: The input drive is through the gear mounted on a common shaft with the sun gear. There are twelve groups of planet pinions each group consisting of four pinion. The pinions transmit the drive to the internal toothed outer ring. The ratio of input to output speed is determined by choosing a particular group of planet pinions to transmit the drive from the sun wheel to the outer ring. Moving the control lever causes the cam plate to move radially so that the cams move the pinions in an axial direction either in or out of engagement.
Patent DE-2421598-A1 (DE)
Title: Lubrication arrangement for cable terminating machine - applies thin oil film to one side of terminals
Inventor: WEBER ALOIS
IPC: H01R43/04
Filed: 1974-05-04
Abstract: The application is to automatic cable terminating machines in which a continuous ribbon of terminals is fed to a work head which bares the cable ends and folds projections on the cable terminals round to make electrical contact with the conductor and give a mechanical grip on the insulation. To assist in reducing wear on the tools the strip of terminals passes through a lubricator before entering the work head. This lubricator may comprise an oil saturated felt, with a groove through which the terminals slidce, contained in a housing with a spring loaded lid. Only the outer surface of the terminals is lubricated so that the oil does not interfere with the electrical connections.
Patent DE-2422920-A1 (DE)
Title: Gear wheel driven displacement pump - has system of inter meshing gears with static and rotating sections and hermetic pumping chambers
Inventor: CINEWITSCH WLADIMIR DOROFEEWIT
IPC: F01C1/08
Filed: 1974-05-11
Abstract: A gear wheel driver displacement pump has one of the gear rims as the cross-bars carrier and this rim is statically mounted, whereas the intermediate gear wheels are mounted such that they can ride on the static gear rim in order to set the other gear rim in motion. The rotation of this rim is transmitted to the working shaft of the pump. The bevel gear serves as the drive component with the external toothed gear rim. The surface of each cross-bar to which is attached an intermediate gear wheel is of cylindrical section of radius similar to that of the external diameter of the intermediate wheel such that the hermitic chambers only receive a minimal corrosive material volume.
