Title: Improvements in and relating to a process and apparatus for the production of highly-pure silicon
Inventor: COWLARD FREDERICK CLAUD
IPC: C01B33/04
Filed: 1956-11-05
Abstract: <PICT:0878763/III/1> <PICT:0878763/III/2> Highly pure silicon is prepared by thermal decomposition of monosilane, in a chamber containing a body of highly pure silicon by heating the silicon body by thermal radiation so as to reduce its electrical resistivity, and thereafter heating the silicon body by induction heating in the presence of monosilane supplied to the chamber, the heating by thermal radiation being terminated when the resistivity of the silicon body has been reduced to a value such that induction heating can maintain the silicon body above the decomposition temperature of monosilane, so that silicon is deposited on the silicon body.  A solution of ammonium bromide in liquid NH3 is placed in flask 1 in bath 2 maintained at -50 DEG C.  Magnesium silicide, prepared by heating Mg, and Si in H2 is tipped into the solution from tubes 3 to form SiH4.  NH3 is condensed in tubes 6 by solid CO2 and acetone mixture 7, and the SiH4 passes through heat exchanger 8, where it is cooled to -100 DEG C. by gaseous N2 cooled by liquid N2, to remove residual NH3, and is condensed in boiler 12 by liquid N2.  The boiler 12 is then surrounded by bath 13 at -130 DEG C. after H2 has been evacuated through 24, and the SiH4 is evaporated into vacuum jacketted fractionating column 14, packed with quartz spirals, and condenser 15 cooled with liquid N2.  Evaporated N2 is passed down over column 14.  Pure SiH4 is withdrawn through quartz wool filter 19 immersed in a bath at -78 DEG C. and quartz filter disc 21 to enter quartz decomposition chamber 35 (Fig. 2) through jet 34 directed at liquid silicon globule 36 on seed crystal 37.  The globule is maintained liquid by water-cooled copper inductor loop 40, after the seed has been preheated by focusing a lamp by elliptical or parabolic mirrors. Alternatively, the seed may be preheated by placing an annulus of molybdenum, tungsten, or graphite round the seed coupled to inductor 40, and when the temperature is suitable, 500-1000 DEG C., removing the annulus.  Gases are withdrawn through water-cooled cones 41 and outlet 42.  The SiH4 is decomposed at the surface of the globule 36, while the seed is slowly rotated, and withdrawn from the chamber by holder 39 to build up a continuous rod of silicon. Specifications 878,764 and 878,765 are referred to.  Reference has been directed by the Comptroller to Specification 826,575.

Abstract: 1460688 Separating dichloroethanes; vinyl chloride LUMMUS CO 15 Aug 1975 [16 Aug 1974] 34024/75 Heading C2C 1,1- and 1,2-Dichloroethanes are individually separated from a feed comprising both by introducing said feed into a fractionating zone and also introducing chlorine and ethylene into the fractionating zone and reacting these to produce 1,2-dichloroethane, preferably using a metal halide catalyst, recovering 1,1-dichloroethane in a first stream and 1,2-dichloroethane as a second stream from the fractionation zone. The exothermic reaction of the chlorine and ethylene provides at least part of the heat required for fractionating the dichloroethanes. The process may be built into a process for producing vinyl chloride by chlorination of ethane to give an effluent containing vinyl chloride, dichloroethanes and ethylene, separating these, and using the ethylene in the process of the invention to fractionate the dichloroethanes. Recovered 1,2-dichloroethane may be dehydrochlorinated to vinyl chloride and 1,1- dichloroethane recycled to the vinyl chloride production step.

Title: Missiles
IPC: F42B10/30
Filed: 1966-07-29
Abstract: 1379382 Missiles BRITISH AIRCRAFT CORP Ltd 31 July 1967 [29 July 1966] 34284/66 Heading F3A A missile has at least one fin capable of assuming a position at an angle of incidence such as to cause rotation of the missile about its longitudinal axis, and mechanism operable during flight to alter the angle of incidence of the fin from one fixed value to a lesser fixed value so as to reduce the rate of rotation of the missile. In one example, the missile is discharged from a launcher pointed in the approximate direction of a target and rotates during the first portion of its flight at a moderate speed, a detector directed obliquely to the longitudinal axis of the missile scanning in a cone as the missile proceeds. The target is "illuminated", e.g. by a laser beam, from a source separate from the missile, and when the radiation reflected from the target is picked up by the detector, a mass is discharged laterally from the missile with predetermined momentum such that the missile is deflected and proceeds directly towards the target. The missile contains a hollow charge warhead, the operation of which tends to be spoilt by centrifugal forces if the missile has a substantial rate of rotation when it reaches the target. The rate of rotation of the missile is therefore reduced at the moment when the mass is discharged laterally. As shown in Fig. 1, the missile has an elongated body 2 housing towards its rear end a rocket motor 4 having a central discharge nozzle 6, and towards its front end a hollow charge warhead 8. The position of the detector is indicated by its centre line of observation 10. In the centre of the missile is a mass 12 which can be discharged laterally by a propulsive charge 14. There are four fins at the rear of the missile, two of which 16 can have their angle of incidence altered between 6 degrees and nil, and the other two of which 18 have a fixed angle of incidence of 6 degrees. The fins are all hinged at 20 so that they can be folded rearwards for insertion of the missile into the launcher. Upon discharge from the launcher, the movement of the fins into a radially extending position is assisted by a spring-loaded plunger 22 (Fig. 2) movable along the longitudinal axis of the plunger and having lugs 24 which co-operate with cam surfaces 25 on each fin. The two fins 16 are each hinged to a root member 26 urged towards the nil incidence position by a spring 58 and initially locked in the 6 degree incidence position by a locking member engaging a detent on the root member 26. The locking member is in the form of a spider 28 movable in a fore-and-aft direction on the exterior of a fixed structure including four radial webs 31, each of which supports one of the fins. The spider 28 is urged forwards by a spring intially retained by a latch acted on by a toggle spring so that it has two stable positions. When the mass 12 is discharged, the resultant lateral jerk shifts the latch and so releases the spider 28.
