Abstract: The complex material is intended for making clothing capable of protecting against splashes of molten materials and, more particularly, molten metals in the metallurgical industry. These splashes generally cause serious burns which can be fatal. No current material meets the required conditions of effectiveness. It consists of an assembly of three superposed layers of cloth having specific characteristics: the first layer, intended to form the outer part of the garment, has a relatively smooth surface state and comprises at least one fabric composed mostly of heat-stable or fireproof fibres having a high covering factor; the second, intermediate, layer is thick and has an open structure; and the third layer, intended to form the inner part of the garment, is thin and light.

Abstract: For setting in operation a converter drive for an asynchronous machine with an intermediate-current link and phase-sequence quenching, the commutations in the inverter are synchronized with the commutations in the controlled rectifier and/or all commutating capacitors are discharged before the start-up and/or the direction of commutation is cyclically changed during the startup. This makes it possible to start up the converter also if the intermediate-link current has gaps, and the asynchronous machine is loaded only with hunting torques.

Abstract: The valve comprises a movable closure member and a seat in which the closure member is displaced relative to the seat for varying the gas flow through the valve. According to the invention, the process comprises causing the displacement of the movable closure member by means of a step-by-step motor as a function of the variation of the flow produced by each step according to the geometry of the valve, the type of flow employed and the pressure of the gas on the upstream and/or downstream side of the valve, and then producing a corresponding control signal for displacing in the desired direction the motor through the number of steps corresponding to the calculated flow, the displacement of the motor causing the correlative displacement of the movable closure member.

Abstract: A release mechanism for a high speed circuit breaker comprises a roller rotatably supported on an axle in a mobile contact bridge. A jack is acting in the circuit closing direction on the roller, and the frontal side of the jack is in the form of a slide. The force of a disconnecting spring acts on the contact bridge in a disconnecting direction. The release mechanism to be provided with the connected contact bridge is capable of very rapid release, so that high short circuit currents may be interrupted very rapidly. This is obtained by the slide having a configuration such that in the connected state of the contact bridge the frictional forces acting on the roller are compensated.
