Title: Choking valve
Inventor: CLAUDE CASADEMONT
IPC: F16L55/105
Filed: 1991-03-22
Abstract: The invention consists in producing an extremely robust valve at any point on a tube, without cutting the tube, by introducing this valve through a small orifice.

Title: Revetements formant barrieres de protection contre l'oxydation, contenant une couche de compatibilite.
Inventor: TOBIN ALBERT G
IPC: C23C28/02
Filed: 1991-09-16
Abstract: L'invention concerne un procédé pour produire une surface ductile résistant à l'oxydation pour des aluminiures et alliages de titane, qui prévoit la formation d'une barrière (14) anti-diffusion en métal réfractaire qui est métallurgiquement compatible avec le substrat en alliage. La barrière anti-diffusion est ensuite revêtue d'une couche intermédiaire (16) de liaison en cuivre. La couche de cuivre est ensuite revêtue soit d'une couche (15) de nickel, soit d'une couche (18) d'un superalliage à base de nickel. Si nécessaire, une quatrième couche (20) protectrice formée d'un superalliage à base de fer peut être utilisée pour créer une pellicule protectrice d'oxyde lors d'une exposition à un milieu oxydant à haute température. Ou bien la quatrième couche peut être formée d'aluminiure de nickel qui crée une couche extérieure résistant à l'oxydation. L'avantage de cette solution consiste en ce qu'elle crée une surface résistant à l'oxydation et empêche une fragilisation du substrat en alliage pendant une exposition à haute température sous l'effet d'interactions perturbatrices entre le revêtement et le substrat.

Title: Apparatus for scaling water flowing inside a pipeline under the effect of magnetic fluxes
Inventor: ALPHONSE DORNE JACQUES
IPC: C02F1/48
Filed: 1993-04-09
Abstract: The objective of this invention is to prevent the deposition and the scale growth of the limestone present in the water flowing inside a pipeline, and in any domestic appliance; it enables the existing deposits to be removed. The apparatus (1) is made up of a double generator of intermediate frequencies, transmitting the induction of currents regulated by two spiral cables (2 and 3) wound around the water pipework to be treated (4), the whole being suspended from the pipework by a carrier (5), two indicator lights (6 and 7) controlling the operation; a switch (8) controls the functioning of this module, which is powered via a 220-volt power cable (9). This generator induces, by ionisation, polarisation of the solid particles present in the water, especially the calcium carbonate which, as a result of this treatment, is transformed into a fine powder called "microcrystals". The limestone thus no longer adheres to the walls of the conduits and promotes the descaling on passing through. This device is installed into the existing system without any modification of the latter.

Title: Deformable bicycle frame with articulations and suspensions
Inventor: LOUIS CORNIGLION
IPC: B62K25/04
Filed: 1993-05-06
Abstract: This novel bike frame has been designed for the purpose of forming the most comfortable bicycle possible. Equipped with three shock absorbers, the frame deforms and crushes under the action of the weight of its passenger, thus avoiding the shock transmitted to the spinal column by the unevennesses in our roadways on a conventional bike, and thus giving its users more pleasure. It consists of a big shock absorber (1) fixed at its base by a pin (16) at the top of the handlebar stem (2) and by a fork (7) fixed at the head of this shock absorber (1) to another smaller fork (6) using a large bolt (8) acting as an articulation pin. This fork is connected to two ties (stays) (5) followed by two smaller shock absorbers (3) bolted at the end of the rear fork (4) of the bicycle. The seat tube (10) is clamped between the two forks by a collar (9) and slides in a sleeve (11) mounted on a pin (12) at the bottom of the frame (13), that is to say above the pedal and crank mechanism, and can thus pivot forwards and follow the progression of the big shock absorber (1).
