Title: Tool assembly for conical expansion of metal tube - where compressed air is used to drive end of tube against wall of conical die
Inventor: SCHECK OTTMAR
IPC: B21D51/36
Filed: 1978-05-10
Abstract: A tool set is described where the metal tube is placed on a hollow mandrel and inside a mobile conical die. The tube is pushed onto a spring-loaded, axially mobile bush so the open end of the tube travels over an elastic ring fixed on the mandrel. Compressed air is fed through the mandrel and out of radial holes into the elastic ring, which is thus forced against the bore of the tube so the end of the latter is expanded conically. The bush also contains radial holes through which the compressed air flows to expand the elastic ring; and the tube is forced against the bore of the conical die. Tubes which possess conical ends can be assembled together by inserting the plain end of one tube in the conical end of another tube. This simplifies packing and transport of the tubes.

Title: Electrically-operated door movement control - involves electrical comparison of position data to effect motor switch operation
Inventor: POERSCHKE KARL DIPL ING DR ING
IPC: E05F15/686
Filed: 1978-06-03
Abstract: On rolling or articulated doors, or other large electrically driven doors or gates, control of movement involves a switchable motor acting directly or indirectly on the drive media. The door's position is exactly reproduced electrically, at any given moment, by a resistance position indicator (6) mechanically coupled to the drive media (2-5). The reading from the electric indicator is directly compared with an adjustable electric prescribed value, in electrical determining stages for at least an upper and a lower end setting. These stages activate switchgear for switching the motor on or off, depending on the comparison data. This permits precise door movement control, using non-wearing media which need not be directly fitted to the door itself.
