Title: Improvements in the methods for the production of vitreous silica
Inventor: WINTERBURN JOHN ALEXANDER
IPC: C03C3/06
Filed: 1963-01-29
Abstract: A coating of vitreous silica is produced by directing a heated stream formed from a Si compound and O2 or an oxygen compound, in the absence of free or combined hydrogen, on to a refractory target, e.g. vitreous silica.  The oxygen stream may be mixed with a combustible gas and ignited to form a flame, the Si compound, e.g. SiCl4, being introduced into the oxygen or to the flame.  With combustible gases such as CN or CS2, the heat generated is sufficient to vitrify the deposited silica (Example 3), but with other gases, e.g. CO, electrical energy may be supplied either by passing an electric current between electrodes immersed in the flame, the conductivity of which may be increased by passing the oxygen stream over heated NaCl (Example 4), or by using a plasma torch.  Alternatively, a plasma torch may be used in the absence of combustible gases (Examples 1 and 2).  The plasma torch may comprise a burner tube of silica surrounded by an induction coil, along the axis of which is generated a H.F. electrical discharge. Using a plasma torch, the oxygen stream preferably contains 50-100% elemental O2, optionally with argon. Gases are dried by refrigeration before use.

Patent GB-490022-A (GB)
Title: Treatment of boiler feed water, particularly for the removal of carbon dioxide
IPC: B01J39/00
Filed: 1937-02-06
Abstract: <PICT:0490022/III/1> A method of treating boiler feed-water, which has been softened by means of a base exchange material, comprises introducing into the water an acid substance sufficient to reduce substantially the alkalinity of the water and thereafter subjecting the water at an elevated temperature to reduce pressure, whereby bicarbonates are decomposed and carbon dioxide is removed.  The temperature to which the water is raised is preferably about 95 DEG C.  In the construction shown, boiler feed water that has been softened is passed into the apparatus by pipe F1 and mixes with a small amount of an aqueous solution of sodium hydrogen sulphate supplied from a container S.  The water passes through a coil E and through a pipe F which receives steam from a pipe O so as to raise the temperature to about 200 DEG  F. as indicated by the thermometer R. The water is sprayed into a chamber A which is provided with baffles C and is connected through a pipe D and a pipe G to a vacuum pump H.  The carbon dioxide and water vapour are thus removed from the water which is collected in a tank N by means of a pump J connected to the outlet of the chamber A.  Heat is given up by the gas and vapour to the coil E.  Instead of the continuous process described above the feed water may be treated in batches, each batch being treated in a vat with sodium hydrogen sulphate in solution sufficient to neutralize about 95 per cent of the total alkalinity, and the treated water then passing to the coil E.

Filed: 1968-01-26
Abstract: 1,213,865. Projectile fuzes. GENERAL ELECTRIC CO. 26 Jan., 1968, No. 4278/68. Heading F3A. Fuze for a spinning projectile provided with a safety, arming, and self-destroying arrangement comprises a body 10; a firing pin 32; locking balls 83; a spherical rotor 50, e.g. of aluminium or plastics, housing a detonating charge 54; a viscous damping medium (not shown) between the rotor and wall 46a; and split locking rings 68 and 70. The surface of the rotor may be roughened to cause turbulence in the damping medium as it rotates, and the viscosity of the damping medium may be increased by the incorporation of fine metal or PTFE particles. On firing a projectile fitted with the fuze, the striker pin is moved forwards as the balls 83 move outwardly under centrifugal force along the surfaces 86a to a position where they lock the firing pin against rearward movement. Simultaneously, rings 68 and 70 are radially expanded and permanently deformed into corresponding recesses, whereby the ring 68 no longer obstructs the firing pin, and the rotor is freed and precesses to align the detonating charge 54 with a booster 58 at a rate determined by the damping medium. When the rate of spin of the projectile drops below a certain value, i.e., on striking or overshooting the target, the balls 83 move inwardly to free the striking pin which is then driven by a spring 40 against the detonating charge.
