Title: Apparatus for the Automatic Measurement of Spring Pressure
Inventor: TAYSOM PATRICK ARNOLD
IPC: H04Q1/20
Filed: 1968-07-10
Abstract: 1,162,077. Measuring spring pressure, electrically. STANDARD TELEPHONES & CABLES Ltd. July 10, 1968, No. 32910/68. Heading G1N. In apparatus for automatically measuring the force required to lift a cantilever contact spring of a relay from its seating, a probe 14 is engaged with one side of the spring and moved with constant velocity by a motor 23 in a direction (up or down, as appropriate) to press the spring away from its seating and the motor is automatically stopped when the contact spring leaves its seating and the force then exerted on the probe by the spring is measured. Fig. 2 shows apparatus for testing relays for use in telephone exchange equipment and comprising two stacks of parallel cantilever springs. In use, a relay is positioned on a table 1 which is stepped vertically after each test to pass on to the next spring in each stack. Testing heads 4 and 5 are moved into and out of engagement with the springs at appropriate moments. Fixed deflectors 16, 17 and 18 and a retractable deflector 19 are provided for holding the other springs away from the one being tested. In one arrangement, the output signal from the force transducer 13 is differentiated during movement of the probe 14 to press the spring away from its seating (which may be an adjacent spring) and the sudden change in the value of the differentiated signal when the spring leaves its seating is detected and used to stop the motor 23 and to send a signal along an appropriate one of three lines according as the measured force, "the spring pressure", is above, within, or below, limits set on two comparators. If within limits, the output signal of the transducer is stored. If outside limits, appropriate operation of a twister 20 is initiated to bend the spring in the direction to correct its spring pressure. The spring is then automatically retested. If the spring pressure cannot be corrected, a fault signal is generated. In another arrangement, the probe is merely moved a fixed distance, it being assumed that the spring will then have left its seating. The output signal of the transducer is then measured and compared with the set limits as before. The apparatus is controlled automatically by instructions from a punched card reader.

Title: Improvements in or relating to processes for the production of graphite
Inventor: SON HUGH WILSON DAVID
IPC: C04B41/88
Filed: 1956-10-29
Abstract: The permeability of graphite to gas or liquids is reduced by coating its external surface with nickel, the surface being heated to at least the decomposition temperature of nickel carbonyl and subjected to an atmosphere of or containing nickel carbonyl and the resulting nickel deposit being heated so that it flows.  The surface is preferably heated by induction to a temperature of 200 DEG -500 DEG C. when contacted with said atmosphere which may consist of nickel carbonyl entrained in hydrogen or nitrogen.  Part of the atmosphere may be bled off to deposit nickel upon glass beads as a control.  The final heating is performed at a temperature of 1200 DEG  1400 DEG C., and the resulting coated graphite may be used in a nuclear reactor as a moderator, fuel element channel, supporting tube for fuel elements in a fuel element channel, and as cladding material for fuel elements.

IPC: C04B40/02
Filed: 1947-12-18
Abstract: In the setting and hardening of mixtures of finely-divided reactive solids and a liquid, e.g. mixtures of finely-divided alkaline earth compounds such as lime, and siliceous or aluminous materials, e.g. silica or an aluminosilicate, and water, the mixture is subjected, in the presence of the vapour phase of the liquid, to the temperature necessary for promoting the reaction, the atmosphere being at first non-evaporative until the mass is at least partly self-sustaining and then evaporative so that the mass is completely integrated and dried. The necessary conditions may be obtained by controlling the pressure and/or temperature to ensure an atmosphere saturated with the vapour during hardening and unsaturated during removal of the liquid.  The finely-divided solids may be suspended in the liquid in a solids : liquid ratio of less than 1 : 1 and the mix is placed in a mould which is inserted in an autocalve to which a saturated atmosphere of the vapour of the liquid is supplied.  The reaction between the solids commences at the outer surface of the mass and gradually spreads inwards, and when the surface is sufficiently strong, removal of the liquid therefrom can be commenced.ALSO:In the setting and hardening of mixtures of finely-divided reactive solids and a liquid, e.g. mixtures of finely-divided alkaline earth compounds such as lime, and siliceous or aluminous materials, e.g. silica or an aluminosilicate, and water, the mixture is subjected, in the presence of the vapour phase of the liquid, to the temperature necessary for promoting the reaction, the atmosphere being at first non-evaporative until the mass is at least partly self-sustaining and then evaporative so that the mass is completely integrated and dried.
