Patent FR-2675873-A1 (FR)
Title: Device for blocking a differential
Inventor: ALAIN DELORE
IPC: F16H48/26
Filed: 1991-04-26
Abstract: The invention relates to a device for partially blocking the differential of a motor vehicle making it possible to increase the torque transmitted between the left and right wheels when these wheels are rotating at different angular velocities. It is made up of a differential housing (1) which is closed and rendered leaktight to the high-pressure fluid. Internal partitioning (2) divides this casing into independent chambers filled with high-pressure hydraulic oil. The relative movement of the sun pinions and planet pinions transfers the hydraulic fluid from one chamber to the other via the spaces between the teeth. The increase in pressure in these chambers will oppose this movement, transmitting a driving torque to the wheel which still has adherence. This torque is a function of the speed of the wheel which is slipping. The implementation of the system for blocking the differential is automatic.

Title: Ploughshare for a tool with teeth for working the ground
Inventor: RENE KIRSCH
IPC: A01B23/02
Filed: 1991-07-16
Abstract: The invention relates to a ploughshare for tools with teeth for working the ground, the upper face of which forms a ramp (incline). According to the invention, the ramp is made up of three zones denoted "leading zone (zone of attack)" (1), "central zone" (2), and "trailing zone" (3). The angle (e1, e2) which defines the depth of penetration of the ploughshare in the leading (1) and trailing (3) zones is close to 40@ and that of the central zone is less. By virtue of this geometry, the penetration into the ground remains satisfactory even once the leading zone has been totally worn.

Title: Dental implant of the cylindrical post type, provided with a hollow impression intended for reinforcing a prosthetic (false) tooth by replicating calcinable elements
Inventor: JEAN-CLAUDE YEUNG
IPC: A61C8/00
Filed: 1991-11-07
Abstract: The implant (1) comprises a cylindrical post with a smooth head (2) extended by a threaded rod (3), with a nominal diameter equal to the diameter of the head (2). A hollow impression (4) is made in this head, with a flat bottom forming a radial bearing surface, and regular side surfaces, parallel to the axis. The cross-section of the impression (4) consists of eight segments, each covering an angular sector of 45@, centred on the axis of the post. These segments are alternately chords (such as 41) and arcs (such as 45, 46) of a circumscribed circle. The impression (4) is extended by a blind, tapped axial channel (5). The impression (4) is intended to receive, without rotational play, a complementary projection of a prosthetic tooth reinforcement, made by replicating a model made of a calcinable material. The chosen impression shape provides the impression and projection walls with better strength, and allows the flat faces of the reinforcement projection to be rectified with reference to the circumscribed cylinder.

Title: Method of manufacturing duplex and triplex tubes (pipes) based on zirconium
Inventor: YVON MILLET
IPC: B21C37/06
Filed: 1992-01-03
Abstract: The invention relates to a method of manufacturing duplex and triplex tubes based on zirconium. This method consists in preparing an outer tubular blank intended to form the covering sheath (4) of the tube and an inner tubular blank or core unit which may or may not be internally lined, the said blanks being obtained by machining bars in the extruded hollow-billet state, and then subjecting the outer blank to an extrusion operation with upsetting on a punch (2) and in slipping it over the inner blank to which it is subsequently joined by welding the ends. The invention finds its application in the production of composite tubes with reduced consumption of zirconium, whilst still obtaining good adhesion between the components of the said tube.

Title: Automatic forging installation - for the continuous production of blanks from long products
Inventor: ROGER LOUBIERE
IPC: B21K11/02
Filed: 1992-09-28
Abstract: A process for the automatic and continuous forging of components from long primary products consists of:- (a) not separating the blank (B) from the long product (1) in order to form, between the pressing post (3) and the scrap cutting post (9), a long continuous blank (G) that comprises a succession of blanks (A-B) connected by the scrap (C) which extends horizontally across the various operating posts: (b) carrying out the stamping phase during which the cutting impressions (29-30) are made; (c) carrying out the trimming phase by cutting following the stamping phase, during which the stamping impressions (25-26) are separated and at the moment when the long blank (G) is locally at an appropriate temperature; (d) exerting, during both stamping and trimming phases, a longitudinal traction on the blank with a constant value and in the downstream direction, in order to gather in that way the longitudinal deformations of the blank; and (e) only after the trimming phase to separate the scrap (C) from the elongated blank (G). USE/ADVANTAGE - The process is used for the automatic and continuous forging of components from long products such as wire or flats, in particular for the production of key, cutting blade, plate and other blanks. The process is automatic and continuous eliminating the need for intermediate stocks, ensures regular metallurgical quality and reduces the operating personnel requirements, thus reducing operating costs. It also reduces the overall fabricating time.
