Title: Method of producing bearing bushes - involves transfer of bush through bending, sizing and grooving stations in integrated work cycle
Inventor: BRANDT HORST DIPL ING DR
IPC: B23P13/00
Filed: 1991-03-09
Abstract: The bearing bushes (13a...13e) are produced complete from laminated strip by transfer through a series of adjoining work stations, including a final groove broaching station, in an integrate work cycle. The production machine has a bending station (3), ring tool (4), sizing station (5) and groove broaching station (7). Passing through the stations is a transfer mandrel (9). At the bending station strip is fed in and wrapped round the mandrel. Each forward stroke of the mandrel feeds formed bushes stage by stage through the succeeding operations and into the broaching station; each return stroke pulls the broaching tool (11) through the bush to produce the grooves. The next forward stroke ejects the completed bush from the machine. ADVANTAGE - Greater econmomy of production of high quality bearing bushes.

Title: Rotary comber - has machine to remove and replace pointed and round pins
Inventor: KOEPPLER HORST
IPC: D01H5/02
Filed: 1991-03-27
Abstract: In pin assembly machine pointed pins and round retaining pins are inserted, and likewise may be withdrawn, in a continuous manner, by mechanical means. Pointed pins are pref. held in the retaining shape with the round pins crosswise, and which are only held in a groove on each side of the plates. Rotary comber plate is held in the machine and rotated so that the round pins are lifted by the presser which is actuated by the bolt and lever and are pref. set into position by the fixing lever. All the round pins are removed at the point (11), so that they enter the slide, then into the chute at the side of the machine. Pins are pref. removed by the lifter and lever system and enter the channel and along the chute. When assembling the pointed pins and the round pins, the procedure is reversed.

Title: Measuring speed and direction of Earth's motion in inter-stellar space - involves using Michelson effect produced by radio waves
Inventor: KAULE HANS
IPC: G01P3/50
Filed: 1992-05-22
Abstract: The method involves the use of the Michelson effect produced by radio waves. The single radio wave is divided between two channels, one with a greater propagation path capacity coefficient than the other. The closely adjacent channels are rotated about an axis centrally perpendicular to both axes. A radio wave transmitter at one end of the propagation paths transmits only purely undamped, uniform amplitude waves of constant wavelength into the paths. The waves are received by receivers at the other path ends and transformed into an average wavelength by superimposing one auxiliary frequency in both receivers, rectifying the resulting beat and amplifying the result. USE/ADVANTAGE - Enables highly accurate Earth's direction measurement.
