Patent FR-2548935-A1 (FR)
Inventor: GOURMEL YVES
IPC: B22D11/00
Filed: 1983-07-12
Abstract: The vertically ascending casting of a thin-walled metal pipe and integral end fitting from a bath of molten metal is implemented using a housing 12 and a core 14 to mold the end fitting or bell housing and a tubular draw tube 6 to mold the pipe shank. The end fitting E is first formed by forcing the metal to rise in the annular space 16 between the housing and the core, simultaneously forming the initial section of the pipe shank. Once the end fitting has solidified it is extracted upwardly, step by step, while shank sections are simultaneously withdrawn from the metal bath. These sections are also solidified step by step along a tapering front S in the bath until the desired length of pipe T has been obtained.

Title: Remote-controlled electric lock
Inventor: AROUETE JEAN
IPC: E05B47/00
Filed: 1984-06-05
Abstract: Electro-mechanical locking device enabling the remote-controlled closing even if the bolt is not exactly facing the striker, i.e. when the door is incompletely brought back to its closure position. It is comprised of an electro-magnet (20) attracting a movable plate (4) which, by a double obliquity slot (17), mobilizes a ball-bearing (6) which projects a bolt (2) into a striker with two ball-bearings to facilitate the relative bolt-striker positioning. A stud (27) driven by an electro-magnet may block the mechanism of the lock. The invention is particularly intended to the remote-controlled electro-mechanical locking of locks of buildings, of lock-chambers in banks, of emergency exits in public places and of all kinds of doors in general.

Title: Continuous carbon fibre filament mfg.
Inventor: MASAMI WATANABE
IPC: D01D4/02
Filed: 1984-01-06
Abstract: A pitch with a mesophase content is developed from a petroleum pitch as the raw material. The resulting mesophase is aged, so that only the mesophase content is allowed to melt and coalesce. The 100% mesophase is sepd. for melt spinning, using spinning jets with an out-of-round cross section. The spun filaments are heat-hardened and carbonised to give continuous carbon fibre filaments. The arrangement of the carbon matter is formed in a structured or spontaneous way, or the form is a turbulent flow, to give virtually a circular cross section.
