Title: Semiconductor material

Filed: 1961-12-27
Abstract: A high resistivity monocrystalline N-type silicon layer is formed on a monocrystalline low resistivity antimony and/or bismuth doped N-type silicon substrate by deposition from a vapour phase consisting of thermally decomposable chlorine containing compounds of silicon and a donor impurity.  In a typical method, 0.005 ohm cm. antimony doped N-type silicon wafers cut from a melt-grown monocrystal with their major surfaces lying in a 111, 100, 110, or 211 crystallographic plane, are mounted, after surface cleaning, in wells in heater element 12 (Fig. 1).  After raising the wafers to 1170 DEG C. a turbulent flow of hydrogen is passed through the chamber 10 for 30 minutes to prepare the wafers for monocrystalline <PICT:1000731/C1/1> growth.  Turbulence is produced by appropriate design of jet 19, by a mechanical stirrer, or by maintaining steep temperature gradients in the chamber.  A mixture of phosphorus trichloride and silicochloroform is next introduced into the hydrogen flow for 5 minutes to form an 8 ohm cm. N-type layer 12m  thick on the wafers.  The wafers may be left in the chamber for a further 3 minutes with boron trichloride replacing the phosphorus trichloride to form a 10 ohm cm. P-type layer 2-3m  thick. Alternative vapours from which to deposit silicon are silicon tetrachloride and silicon tetrabromide.

Title: Methylphenylpolysiloxanes
IPC: C08G77/00
Filed: 1962-12-18
Abstract: The invention comprises compounds of the formula <FORM:0980107/C3/1> where n is 0 or 1.  They are prepared by the reaction of tetraphenyl disiloxane diol-1,3 or hexaphenyl trisiloxane diol-1,5 with a methyl phenyl dihalosilane in an inert solvent in the presence of a hydrogen halide acceptor e.g. a tertiary amine, in particular pyridine.  The hydrohalide precipitate is removed, then the solvent, and the product is recrystallized. Polymers containing the recurrent unit <FORM:0980107/C3/2> where n is 0 or 1, are prepared by heating the compounds (I) alone at 250-350 DEG  C., or, preferably, with a catalyst at 110-170 DEG  C. A suitable catalyst is a 0.01-1% solution of KOH in octamethyl cyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer. The polymers have M.W.'s of 10,000 to 5,000,000 and are soluble in benzene and toluene.  Copolymers can be made in the same way from mixtures of compounds (I) with themselves or other cyclopolysiloxanes, which may contain halohydrocarbon, alkenyl or cyanoalkyl radicals, or with cyclosiloxanesilphenylenes, e.g. those of Specifications 980,101, 980,102, 980,103, 980,104, 980,105, 980,106, 980,108 and 980,109.  Homopolymers and copolymers containing units (II) can be cross-linked by irradiation, e.g. with 50,000 to 20,000,000 eV electrons, and copolymers containing vinyl groups or adjacent methyl groups may be cured with conventional free-radical (e.g. peroxide) curing agents.  Fillers may be added before cure, if required, and may suitably be silica (aerogel, fumed, precipitated), TiO2, FeO3, Cr2O3, CaCO3, CaSiO3, CdS, lithopone, asbestos, talc, glass fibres or carbon black. Examples describe the preparation, polymerization and cure to a silicone rubber of each of the compounds (I), and the copolymerization of the tetrasiloxane (I) with octaphenylcyclotetrasiloxane and the cure of the product.

Abstract: 1,155,106. Roller mills. SOIL FERTILITY Ltd. 20 Oct., 1967 [24 Oct., 1966], No. 47701/66. Heading B2A. In a machine for separating hard objects, e.g. flint, from friable material, e.g. chalk or limestone, a mixture of the objects and material is first passed between a plurality of resilient crushing rollers 6 or 22 and mov-  able thrust-receiving means 1 or 15 so that the friable material is reduced in size. The mixture then passing on to a screen, e.g. 14, which effects separation between the hard objects and the crushed friable material. In Fig. 1, the thrust-receiving means consists of a conveyor belt 1 composed of interlocking metal plates, a backing plate 7 being provided to take up the thrust. Each roller 6 is mounted on a. shaft 9 connected by sus- 'pension means 8 to a Shaft 10 which is pivotable at one end 11 and is loaded with weight 12 at the other end which is free to move vertically. The rollers are arranged in two sets which extend across the width of the conveyor belt and may be mounted side-by-side or in staggered relationship. The rollers may be driven only through contact with the material on the belt. Two crushing machines may be arranged in series. In Figs. 3 and 4, a driven thrust-receiving roller 15 is mounted adjacent crushing rollers 22 which rotate freely on a common axle 23 clamped by means of U-bolts 24 to leaf springs 20. Each leaf spring has one end pivotable at 21 to a support 19 and the other end free to move between limits set by a stop 25 and the end of an adjustable screw 26 passing through a rigid mounting 27. In a modification the rollers 22 are driven and the roller 15 rotates freely.

In apparatus for feeding plates, e.g. accumulator plates on to a stack, four magazines are placed at 90 degree intervals round a stacking table 11, Fig. 2, and the plates are fed from the bottoms of the magazines, one from each in turn, by pusher plates actuated by pneumatic rams 28 until the stack is complete, when the table is lowered by a ram 12 to deposite the stack on conveyer belts, which are then moved by a ram 14 to move the stack clear of the table. As described, the plates stacked are a negative plate, a spacer, a positive plate and a spacer, the cycle being repeated as often as required, and a final negative plate forms the top of the stack, the spacer having projections extending alternately downwards and upwards. The plates pass on to the stack over guide rods 29 supported on horizontally adjustable supports 30 forming side guides for the stack. The rams 28, 12, 14 are operated by six valves actuated by cams on a shaft 47, Fig. 5. A valve selector bar is provided which in one position allows only the four valves for the rams 28 to be operated in repeated succession, and in a second position allows only the valves for the rams 12, 14 to be operated.
