Patent DE-2840087-A1 (DE)
Inventor: SCHEFER ARNOLD
IPC: F16B13/12
Filed: 1978-09-14
Abstract: An integrally formed expanding dowel is provided with an installation aid (6) which is used for fixing the attachment screw (8). The installation aid is located in the region of the dowel neck (3b) and consists of one or more web parts (6a, 6b) which engage in a thread pitch of the attachment screw. The installation aid makes it possible to drive the dowel into a retaining hole by applying force to the screw, without said dowel spreading apart prematurely. When the screw is turned to spread said dowel apart, no shear force is necessary, which would enable displacement of the dowel. <IMAGE>

Title: Sorting of component parts during mfr. - using microprocessor causing air jet to remove defective parts as detected by photoelectric cells
Inventor: SCHMIDT GEB JAEKEL KARIN
IPC: B07C5/02
Filed: 1978-12-27
Abstract: In the mfr. of small parts it is often necessary that they be delivered to a machine tool in a given attitude. This requirement is achieved by feeding the parts (2) through a tube (4).

Title: Yarn twisting or cladding mfg. - using mantle to contain ballooning yarn and stabilise it for high speed working
Inventor: MAAG FRITJOF DIPL ING DR ING
IPC: D01H1/42
Filed: 1979-12-24
Abstract: There is a mantle round the bobbin to contain the ballooning yarn, and stabilise it, during the twisting or yarn cladding operation. The mantle rotates on upper and lower mountings to allow a core yarn to be fed in through one hollow mounting, if required, and the twisted or clad yarn to be drawn out through the other mounting. The bobbin is rotated to induce a yarn balloon within the mantle, rotating with it, and the bobbin can be wound with several yarns, or there can be several bobbins, to give the yarn twisting action. The axis is hollow, so that a core yarn can be passed through, and the bobbin yarn twisted round it for cladding by the ballooning yarn within the mantle. The bobbin can also be prevented from rotation. The mantle and spindle are mounted on discs or drums which connect to the drive. The inner surface of the mantle has a narrowing surface where in contact with the yarn.

Title: Guideway for machine tool - has rotary cylindrical guide driven at speed that keeps sliding friction low
IPC: B23Q1/26
Filed: 1980-01-29
Abstract: The moving part (131) of the machine (e.g. a table or a tool head) executes movements in two orthogonal directions. The speed of movement can be made very small for at least some of the time. The moving part travels along guides (132) (e.g. round bars) whose surfaces are enclosed at least over a sector by a sliding surface (167) on which the moving part slides. The guides rotate and are driven at a peripheral speed that holds the frictional resistance between the two sliding surfaces (132,167) within a region characteristic of a low value of sliding friction. The guides may also be rotating shafts on which the moving part rests via sliding pieces. Rotary guide cylinders (132) may be on the moving part and move along guideways (137) in the stationary part (17) of the machine.

Title: Radiographic amplifier and t.v. monitor system - uses glass-fibre optical link with camera and automatic rejection of over exposed images
Inventor: HORBASCHEK HEINZ ING GRAD
IPC: G01N23/04
Filed: 1980-02-11
Abstract: The system consists of a central control unit (1) and an X-ray tube (2) in whose briefly lasting radiation field a patient (3) is placed. The image on the projection screen is enhanced in a radiographic amplifier (4) and then passed via a fibre optic link (5) to the sensitive layers of a television camera (6) whose scanning beam is controlled by the central unit (1).
