Title: Dowel for anchoring bolt in stone - has sintered body with fingers expanded by steel tapered plug forced in by bolt
Inventor: PRUETER HEINZ GUENTHER
IPC: B22F5/00
Filed: 1976-11-19
Abstract: A dowel for securing an anchoring bolt in stone etc. has a casing (1) made of sintered metal. It has four slots (2) along one end, about half its length, forming four fingers (1b) which are spread apart by a steel expanding member (4) which can be barrel or cone shaped.

Title: Crosslinking blown thermoplastics tube on leaving extruder - esp. by heating before it reaches final diameter
Inventor: KUNZE DIETER DIPL ING
IPC: B29C48/21
Filed: 1977-04-29
Abstract: The method consists of extruding tubular sheet through an annular die, inflating the tube to expand it to a larger dia. and keeping the tube closed at a certain distance from the die. The tube is cross-linked in a zone within the inflating region, before the tube dia. has been fully expanded to its max. value. Pref. the tube, after passing through the inflating and cross-linking zone, immediately enters a stretching zone in which it is expanded to its final dia. using the same internal pressure. The die may be a double-ring die which simultaneously expels and internal layer of adhesive to coat the inside of the tube before the cross-linking operation. The process is for the prodn. of any plastics cross-linked tube by the blowing process e.g. PVC or polyethylene.

Title: Hobbing cutter for gear teeth - has two cutting edges with different rake angles for better chip formation
Inventor: KOCH FRANZ ING GRAD
IPC: B23F21/16
Filed: 1978-07-08
Abstract: The cutter for roughing or finishing gear teeth has two cutting edges on each tooth. One cutting edge (9) has zero rake angle and this edge removes metal from the flanks of the gear teeth. The second cutting edge (14), has a negative rake angle and removes metal from the root of the inter-tooth space. By dividing the cutting process in this manner, the chips produced during cutting are so shaped that they break away easily and do not jam the cutter and so avoid the risk of damage to the cutter and to the gear teeth.
