Title: Organosilicon compounds
IPC: C08G77/50
Filed: 1956-06-01
Abstract: The invention comprises sulphur-containing polymeric organosilicon compounds containing at least two <FORM:0800754/IV (a)/1> groups per molecule in which groups the carbon atoms are parts of separate aliphatic hydrocarbon radicals containing two or more carbon atoms or aliphatic aryl hydrocarbon radicals, each of which is attached to a silicon atom, any remaining valencies of the silicon atoms being satisfied by hydrocarbon, halohydrocarbon or hydrocarbonoxy radicals or oxygen.  They are prepared by reacting sulphur dioxide with a silicon compound containing an alkenyl group, e.g. vinyl, allyl, hexenyl, octadecenyl, styryl, vinyltolyl, alkylphenyl or hexenylphenyl.  A catalyst is necessary and may be ultra-violet light or an oxygenated compound which is not as strong an oxidizer as nitric acid.  Suitable compounds include amine oxides, metallic chlorates and nitrates, ozonides of olefines, and peracids and peroxides.  The alkenyl-containing silicon compound may be a silane of the general formula R4Si or RnSi(OR1)4-n or a partial condensate thereof, a siloxane of the general formula RnSiO 4-n/2 and copolymers thereof, or a silcarbane of the general formula RnSi(R11) 4-n/2 in all of which there is at least one alkenyl group per molecule, the remaining R, R1 and R11 groups being hydrocarbon or halogenated (particularly chlorinated and fluorinated) hydrocarbon radicals.  The amount of SO2 used in the reaction may be less than sufficient to react with all the alkenyl groups but is preferably in excess when it may act as a solvent for the addition product.  The products are useful as lubricants or as intermediates in the preparation of other resins and rubbers.  Copolymers with olefines may be prepared by reacting, for example, vinylmethylsiloxane and n-butene with sulphur dioxide.  Other unsaturated compounds also mentioned for this purpose include diolefines, alcohols, esters, acids and cyanides.  In the examples, sulphur dioxide is reacted with: (1) and (2) monovinyl mono (chlorotrifluorocyclobutyl)) hexamethyl cyclotetrasiloxane, in the presence of sodium nitrate; (3) a copolymer of 4 mol. per cent MeViSiO and 96 mol. per cent Me2SiO, to give a product which is compounded with fume silica and heated with benzoyl peroxide to give a vulcanized rubber; (4) divinyltetramethylsisiloxane; (5) allyltrimethylsilane, to give a product having the grouping: <FORM:0800754/IV (a)/2> (6) hexenyltriethoxysilane, to give a product having the grouping: <FORM:0800754/IV (a)/3> (7) a copolymer of 10 mol. per cent p-styryl siloxane, 20 mol. per cent PhMeSiO, 20 mol. per cent MeSiO 3/2 , 20 mol. per cent a ,a ,a -trifluorotolylmethylsiloxane, 20 mol. per cent pentachlorophenylmethylsiloxane and 10 mol. per cent octadecylcyclohexylsiloxane, to give a product containing the group <FORM:0800754/IV (a)/4> (8) a copolymer of 50 mol. per cent vinylallylsiloxane and 50 mol. per cent vinyloctadecenylsiloxane; (9) the silcarbane of the formula: <FORM:0800754/IV (a)/5>

Title: Improvements in alternating current circuit breakers
IPC: H01H33/75
Filed: 1935-06-13
Abstract: 458,309. Liquid - blast switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, TRENCHAM, H., Oakthorpe, King's End, Ruislip, Middlesex, and COX, H. E., 96, Burnley Road, Dollis Hill, London. June 13, 1935, No. 17076. [Class 38 (v)] In a liquid-break, explosion-chamber type of switch, the axis of separation of the contacts is horizontal and the wall of the explosion chamber 3 has a vent or vents 8 close to the point of contact-separation and so disposed as to be just below the level of liquid (shown dotted) in which the chamber is immersed. With this arrangement, the arc formed between the contacts causes a blast of liquid to take place through the vent with little restraint owing to the small head of liquid above the chamber wall and the arc-products find a ready means of egress. A vent 10, or a space 9 at the point of entry of the movable contact 1, prevents undue pressure-rise in the chamber. The chamber 3 is of insulating material carried on an end plate 4 in which is a pin 5 guiding the fixed contact 2, which is urged by a spring 6 against a shoulder 7 on the pin 5. The pin of the supporting insulator is attached to the resilient cup 11. In a modification, Figs. 2, 3 (not shown), the vent is arranged to be covered by the movable contact during the initial separation thereof, by tapering the side walls of the chamber inwards until they meet the sides of the movable contact adjacent the vent. This arrangement causes initial compression of the gas bubble, followed by expansion and cooling with consequent arcextinction. The Provisional Specification describes means for preventing ingress of oil to the chamber through the vents when the movable contact is withdrawn, and states that the movement of the latter may be overcompensated to promote an egress of oil.
