Patent EP-0330290-A1 (EP)
Inventor: SONNEVELD PIETER JAN
IPC: H01M12/08
Filed: 1989-02-23
Abstract: Described is an electrode material (3) for use in a storage battery half-cell of the type in which a suspension of particles of active material (1) circulates. Upon charging such a half cell the electrode material according to the application prevents the formation of a strongly adhering precipitate of active material, such as zinc, on the electrode material. The electrode material comprises for that purpose, at least at its surface, an electrically conducting ceramic material. The application also concerns a storage battery half-cell comprising such electrode material and a storage battery comprising one or more storage cells each comprising two of such half cells.

Abstract: In a method of joining a metal matrix composite (cermet) or ceramic tool material 1 to a metallic holder 2 by diffusion bonding through an intermediate metallic layer, the tool material 1 includes at least one carbide, nitride or boride in the matrix. In one example, the tool material includes titanium carbide and titanium nitride in the metal matrix. The intermediate metallic layer is chosen from a group consisting of nickel, titanium and tungsten. The tool holder metal 2 is a ferrous alloy. The intermediate metallic layer is placed between the tool material and the metallic holder, and heat and pressure are applied for a controlled period to diffusion bond the tool material to the metallic holder. Articles made by the method include a blank holder, a punch, a die and various wear surfaces of a continuous extrusion apparatus.

Abstract: The invention is a method and apparatus that comprises supplying a mixture of gases to a constricted plasma arc. The mixture comprises a gas that will sustain the plasma arc at the lower voltages typical of electric-arc welding and in the absence of a plasma and a gas which provides good heat transfer characteristics. The relative proportion of the gas that will sustain the plasma arc at the lower voltages present in the mixture is large enough to support the plasma arc, and the relative proportion of gas having good heat transfer characteristics present in the mixture is small enough to prevent failure of the arc at the lower voltage. A voltage drop is maintained which is high enough to maintain the plasma arc using the gas mixture while low enough to operate at a substantially constant current using a low voltage constant current power supply.

Abstract: Une canule d'aspiration chirurgicale comprend un corps allongé (144) ayant un conduit d'aspiration longitudinal (138), et un ensemble à clapet (150) supporté par le corps et pouvant fermer le conduit d'aspiration. L'ensemble à clapet comprend un commutateur (152) actionné par le pouce et un plongeur ayant un alésage latéral. Lorsqu'on relâche le commutateur à pouce, l'alésage est aligné avec le conduit d'asipration et une pression d'aspiration communique avec la canule. En poussant vers l'avant le commutateur à pouce, on peut le verrouiller dans cette position ouverte. Lorsqu'on le relâche, le plongeur est sollicité vers le haut par un ressort hélicoïdal (158) de sorte que l'alésage n'est plus aligné avec le conduit, ce qui le ferme. Un assemblage de fixation (140) permet de fixer de manière amovible la canule à l'extrémité avant du corps allongé.

On peut dessaler des dérivés de 1,2-dioxétane essentiellement pures et solubles dans l'eau au moyen de systèmes chromatographiques ou de systèmes de chromatographie par filtration moléculaire mais en l'absence de tampons salins. Dans certaines conditions, on peut combiner la purification et la dessalement en une seule opération chromatographique.

Abstract: An improved steel cord for reinforcing rubber is formed of three steel filaments (1, 2, 3), one having a smaller diameter than the other two, twisted together. The thinner filament (3) is twisted with the two filaments (1, 2) at least partially in contact with them and with the same pitch. When the steel cord is cut at both ends, the thinner filament (3) is retracted inwardly from the ends of the two filaments. This improves the penetration of rubber into the cord and prevents edge separation.

A round through-bore (6) in the rotary tap plug (5) allows, on the one hand, a smooth connection in all conveying directions of the first and second supply pipes (3, 4) likewise in alignment and, in the case of branching at an angle ( beta ), a connection of the first supply pipe (3) with a third supply pipe (12), without changing the surface area of the passage cross-section. In order to achieve a congruent transition of the connecting cross-sections of the first supply pipe (3) with the through-bore (6) via the rotary tap plug even in the case of angled branching, said two bores of equal dimensions inside the rotary tap plug meet at the elliptical plane of section (20) of the medians (21) of the angle ( beta ). In the case of straight passage through the diverter rotary valve, the through-bore (6) connects the supply pipes (3, 4), an adapted bore transition from the outlet on the cylinder jacket surface (14) to the round pipe diameter (D) in the supply pipe (4) being provided to achieve a smooth passage in both conveying directions in the supply pipe (4).
