Patent DE-3925348-A1 (DE)
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/23
Filed: 1989-07-31
Abstract: A valve gated injection molding system having a double acting pneumatic rack and pinon valve pin actuating mechanism. The melt passage branches in a manifold (14) from a central inlet (12) and flows along the valve pin (28) in a central bore (16) in the nozzle (18) to the gate (20). A pneumatically driven piston (96) pivots a toothed pinion member (84) mounted in a slot (74) in the manifold (14). The pinion member (84) engages a toothed rack member (76) which reciprocates along a straight line in the slot (74) in the manifold and engages an enlarged head (66) of the valve pin (28) in a slot in the rack member (76). Lateral forces from the pinion member (84) are absorbed by sliding contact of surfaces of the rack member (76) against matching surfaces of the slot (74) and/or a valve pin bushing (26), and are not transmitted to the valve pin (28). This avoids uneven wear and buildup of melt deposits around the valve pin which can otherwise result in leakage and malfunction.

Inventor: KEMPF ANDREAS DIPL ING
IPC: B65H59/38
Filed: 1989-09-08
Abstract: A conductor, specially an optical fibre, is passed to a stranding machine from a driven revolving plate via a deflection pulley. The fibre lies in a coil on the plate. A hinged bracket above the plate is joined to a switch and causes the plate and the stranding machine to stop, unless the strand has been raised by the bracket over a defined area. Pref. the plate (1) carrying a coiled optical fibre (2) is revolved in the direction of the arrow by a drive (not shown). Within the shaded area (3) the strand is raised by the bracket (6) and goes over a guide ring (4) and deflection pulley (5) to a buffer store (10). A switch (9) cuts out the drive for the plate and for the stranding machine if the bracket fails to raise the fibre (2). ADVANTAGE - This prevents loops from forming and causing damage to the optical fibre.

Title: Torque drive element for cutting tools - has torque drive through matching circular arc rosette sections on tool shank and in spindle nose
Inventor: ENDER GERHARD
IPC: B23B31/113
Filed: 1990-05-15
Abstract: Existing methods of transmitting torque to the shank of a cutting tool give rise to noise and wear esp. under shock loads.  To solve these problems the tool shank has a rosette-profile driving collar which engages with a similar rosette-profile machined at the entrance to the bore of the machine spindle nose. The collar on the tool shank consists of two round-cornered squares (4,5) machined one behind the other simply to produce in end view a rosette of eight circular area.  These fit with clearance into the similar shaped bore mouth of the spindle and provide a large area of contact for torque transmission.  One corner on the tool and in the spindle nose are made to a slightly smaller radius so that the tool will enter at only one angular position. USE/ADVANTAGE - Esp. suited to modular tooling systems for turning, milling and boring operations on machining centres.  REduces noise and wear.  Better torque transmission, esp. to small cutters.
