Patent GB-986624-A (GB)
Title: Process for the production of basic refractories
IPC: C04B41/50
Filed: 1961-07-14
Abstract: Basic refractories are prepared from dolomite and/or magnesia by a two-stage process, in which a product of at least 20% porosity is produced by heating at 1000-1350 DEG  C. and this product is then impregnated with a hydrocarbon and heated at a temperature above the sintering temperature and up to about 2000 DEG  C. yielding a carbon-containing final product.  The first heating may be simply a decarbonating process yielding a product of 50% porosity. Impregnation with hydrocarbon may be repeated several times followed each time by heating to 350-1000 DEG  C. to coke the hydrocarbon. The final heating and the heating at 350-1000 DEG  C. are carried out in a neutral or reducing atmosphere and loss of the carbon and oxide at high temperatures may be reduced by employing pressure in these processes.  The hydrocarbons used are distillation products of coal and tar.  Specification 986,623 is referred to.

Abstract: 1352049 Cathode-ray tube displays SIEMENS AG 19 April 1971 [19 March 1970] 25802/71 Heading H4T [Also in Division G4] The apparatus of parent application No. 43231/69 (Specification No. 1,283,706) in which a series of measured values fed from a store 4 (Fig. 1) are displayed as a curve on the screen of a display unit 1, the oldest measured value being erased when a new measured value arrives, is modified in that, in synchronism with the feeding of the measured values to the display unit, associated additional data qualifying measured values and stored in a store 22 is fed to a control unit to modify the operation of the display unit, e.g. to cause flashing or colour change of the display of the associated measured value. The additional data may indicate for example which of two transmitters is operating. The stores 4, 22 may be plates, drums, delay line stores or shift registers. When drum stores are utilized the store 22 may comprise an additional track on the drum of store 4. In the embodiment of Fig. 1 in which an unblanking pulse is fed to the display unit 1 from a comparator 25 when the count in a counter 26 pulsed from a source 16 represents the stored data, the pulse is fed via a gate N2 which passes the signal only when no signal is present from a gate N1. Gate N1 is controlled by the additional data in store 22 and a clock source 27 so that when the data is present gate N2 is alternately enabled and disabled to cause the displayed value to flash. In the embodiment of Fig. 2 (not shown), in dependence on whether additional data is present or not one of two gates (N3, N5) is enabled to pass the comparator pulse via one of two sets of differently adjusted potentiometers (PR1, PG1, PB1; PR2, PG2, PB2) in a colour television set to vary the colour of the display.

Abstract: 1334209 Pyrotechnic actuating means for valves FRANCE ARMED FORCES MINISTER OF 6 June 1972 [8 June 1971 3 March 1972 (2)] 26413/72 Heading F2V [Also in Division F3] A device for driving electrical switches in missiles, torpedoes and mines, or a shutter for an igniter or military propulsion unit, or a valve, comprises a slide which is moved step-by-step in response to the sequential firing of a plurality of pyrotechnic igniters. In one embodiment, Fig. 4, a housing 2 contains the slide 1 and the igniters 11, 11A, &c. The combustion gases from the igniter 11 retract a lock 4 and the slide is driven to the left by gases entering a chamber 23. A piston 3, however, remains stationary and a spring 10 becomes compressed owing to the relative movement of the slide. As the chamber 23 reaches a passage 9 adjacent the igniter 11A, the gas pressure is relieved and the piston 3 is moved to the left by its spring. The locks 4 and 5 automatically lock the slide and piston in position adjacent the next igniter 11A. The sequence is then repeated. An automatically fired igniter (not shown) may be used instead of spring 10 to move the piston. In another embodiment, Fig. 16, the housing 55 for the slide 60 is one of a number of modules which may be placed end-to-end. The slide is locked by a breech block 64. A pivoted latch 67 lifts the block 64 when the gases from an igniter 71 act on a piston 68. As the piston reaches the end of its stroke, the latch releases the block altogether and it snaps down behind the displaced slide to form the end wall of the next combustion chamber. In another embodiment, Fig. 19, a rotor 80 is locked by a piston 88. The piston is displaced inwardly to unlock the rotor when the opposing igniter 83 is fired. As the piston moves inwardly, it acts on a lever 90 which is connected at one end to the rotor through a lost motion coupling 94, 99. At its other end the lever has a ball 91 which is engaged in a recess 92 in the rotor housing 81. A spring 93 is stressed by movement of the lever and rotates the rotor towards the next igniter where it is re-locked by the piston. The ball 91 also moves into the next recess. Filters 95 filter the gases from the igniters.
