An arrangement usable in an electrochemical generator and elsewhere comprises a compartment defined by an envelope in a portion of which there is a recess external to the compartment, said recess surrounding an opening in which a conduit is arranged. The arrangement is characterized by the fact that the conduit comprises a shoulder resting against the bottom of the recess and is further characterized by the fact that a weld material disposed in the recess on the outside of the shoulder forms an assembly between the envelope and the conduit, the shoulder resting against the bottom of the recess either directly or via a thin film of the weld material.

An improved cooling fluid for an apparatus for the manufacture of a wire by projecting a jet of liquid metal or metal alloy through a nozzle into a cooling enclosure containing the cooling fluid is characterized by the fact that the cooling fluid consists of a mixture of a gas and steam, the gas and the steam being compatible with the jet, the gas furthermore being at a temperature below the condensation point of the steam, so as to transform at least a part of the steam into liquid droplets.

Cooling fluid for the manufacture of wire

An installation for the manufacture of wire by projecting a jet of liquid metal or metal alloy into a cooling fluid and having a crucible for containing the liquid metal or metal alloy and provided with at least one nozzle, means for exerting a pressure on the liquid metal or metal alloy sufficient to project it in the form of a jet through the nozzle into the cooling fluid, and a cooling enclosure for containing the cooling fluid and arranged at the outlet of the nozzle, is characterized by the fact that the cooling enclosure comprises, in the portion thereof adjacent to the nozzle, means for imparting to the cooling fluid a flow which is substantially transverse to the jet, at least over a length approximately equal to the length of the jet.

Process for manufacturing a strip with rounded edges, intended for tire reinforcements, by the rolling of a carbon steel wire of circular cross section between rolls of a rolling mill. In accordance with the invention, the wire is heated as it enters between the rolls of the rolling mill to a temperature above the AC 3 transformation point of the steel used, the heating and the rolling being conducted in a neutral atmosphere.

A reactive cooling medium for apparatus for the manufacture of wire by projecting a jet of liquid steel which contains silicon and manganese through a nozzle into a cooling enclosure containing the reactive cooling medium is characterized by the fact that the reactive cooling medium is a gaseous mixture having an oxidizing power with respect to the steel, at least in the zone adjacent to the orifice of the nozzle, such that the oxidation product of the steel is silica at the thermochemical equilibrium corresponding to the temperature prevailing near the orifice of the nozzle.

Reactive gaseous cooling medium for the manufacture of wire

A medium-hard to hard thin steel sheet and a strip cut or stamped therefrom, both having an increased fatigue strength, are prepared by cold rolling a soft steel sheet, carburizing or carbo-nitriding the soft thinned sheet until a medium-hard to hard thin steel sheet is obtained and subjecting the resulting sheet or strip cut or stamped therefrom to a three-part heat treatment, which heat treatment involves first and second different austenizing operations, each followed by an identical two-step cooling operation, and a third lesser reheating and cooling operation.
