Abstract: 1,071,585. Controlling reactors. COMMISSARIAT A L'ERNERGIE ATOMIQUE. Feb. 2, 1966 [Feb. 8, 1965], No. 4606/66. Heading G6C. [Also in Divisions E2 and F2] A device for mechanically braking an object moving in one sense along a straight path comprises a helical spring 1 extending from a fixed support 6 in a direction opposite to said one sense, having a turn held axially and rotationally relative to the support and having the turns of the spring held to the same axial disposition relative to one another both in repose and under a compressive load, the object including a portion 9 dimensioned to make force fit engagement with the spring means being provided between adjacent turns of the spring so that under compressive load exerted by the object engaging the spring in said one sense the turns, maintaining their relative axial disposition are held against relative rotation in a direction to disengage from the said portion and brake and stop the object, while force applied to the object in a direction opposite to said one sense to release it from the spring causes said turns to move apart axially thereby releasing the turns from said means to permit the spring turns to rotate relative to one another and disengage the object. In the device shown the spring is made from material of rectangular cross-section so that the turns of the spring have surface contact and the means to prevent the turns relatively rotating are pins 3 which fit in pairs of semi-circular recesses 4, pairs of the recesses being in contacting surfaces of the spring and each pair forming a cylindrical hole for the pin. The portion 9 is cylindrical and is slightly greater in diameter than that of the aperture in the spring when this is unstressed and the object has a cylindrical part 8 which is smaller in diameter than the aperture in the spring 9 and which is connected with the portion 9 by a frusto conical portion 10 the frusto conical portion 10 first contacting the periphery of the aperture in the spring as the portion 9 moves towards the spring. In a modification the spring is surrounded by a sleeve which is rigidly connected to the support the sleeve having two inclined slots which receive fingers connected to the spring, the inclination of the slots being such that the unwinding action of the spring is assisted when the object is withdrawn. In an alternative construction the object is hollow and makes a force fit with the exterior of a helical spring. The device is described as being suitable for braking to a halt the free fall of a control rod of a nuclear reactor.

Abstract: 1,194,176. Flexible carbon and graphite fibres. LONZA-WERKE G.m.b.H. 29 Jan., 1969 [30 Jan., 1968], No. 4826/69. Heading C1A. Flexible carbon fibres are produced by heating a fibrous carbonizable starting material to a temperature of up to 1200‹ C., at a uniform heating rate under a pressure of less than 50 mm. Hg, and an inert gas containing from 0À5 to 5% by volume of oxygen is passed over or through the material during the heat treatment without any change in pressure. Preferably the inert gas is nitrogen which contains 1À0-2À0% by volume of oxygen. The heating of the carbonizable fibres may be achieved by a preheated inert gas stream. The fibres may be heated by passing through an oven on an endless screen belt, the inlet end of the oven being at the initial ternperature and the outlet at the final heating temperature. The oxygen containing inert gas stream is preferably introduced beneath the fibre supporting run of the endless belt. The oven may be a tunnel the moving belt passing through the tunnel transversely of shafts leading into the tunnel through which the oxygen containing inert gas stream is direct to the underside of the fibre supporting run of the endless belt, the temperature of the gas-streams issuing from adjacent shafts being their lowest at the inlet to the tunnel and highest at the outlet of the tunnel. The inert gas stream may be removed from the tunnel, cooled to condense the volatile condensation products and then reused after the oxygen content has be raised to the required level. The uniform heating rate may be from 50‹ to 250‹ C. preferably 100‹ to 200‹ C. per hour. The carbonized product may be graphitized by heating at a temperature of from 1300-3000‹ C. in an inert gas atmosphere.
