Title: Halogenated silanes and siloxanes
IPC: C08G77/00
Filed: 1959-06-01
Abstract: The invention comprises difluoropropyl chlorsilanes of the formula CHF2CH2CH2Si(CH3)nCl3-n where n is 0, 1 or 2, and siloxanes derived from them. The silanes are prepared by adding 3,3-difluoropropene to a silane of the formula (CH3)nSiHCl3-n, preferably at 150 DEG to 300 DEG C. in the presence of a peroxide or platinum catalyst. The homo-polysiloxanes are prepared by ordinary hydrolysis followed by heating with an alkali metal hydroxide or alkali metal salt of a siloxane.  To prepare gums and linear polymers, the hydrolysate is heated with alkali metal hydroxide to crack out the cyclotrisiloxane (cf. Specification 832,387) which is then polymerized in the presence of alkaline catalysts (cf. Specification 832,489).  Copolymers containing up to 5 mol. per cent of RSiO1.5, R2SiO or RSiO0.5, where R is methyl phenyl or vinyl, may be prepared by copolymerizing cyclic siloxanes containing these units with the cyclic trimer, or in some cases, with the cyclic tetramer in the presence of alkaline catalysts.  Liquid copolymers are best prepared by copolymerizing in the presence of trifluoromethane sulphonic acid or 1,1,2,2-tetrafluoroethane sulphonic acid.  Examples are given. Uses.-The silanes, as hydrophobing agents for ceramic, wood, etc.; the siloxanes, as lubricants, dielectric fluids, hydraulic fluids, water-repelling agents and intermediate in the preparation of rubbers and resins. Specification 823,519 also is referred to.

Title: Improvements in the suspension of vehicles
IPC: B60G11/32
Filed: 1948-07-12
Abstract: 674,224. Vehicle suspensions. SOC. DES BREVETS J. A. GREGOIRE. July 12, 1948 [July 11, 1947; Oct. 17, 1947], Nos. 18738/48 and 18739/48. Class 108(ii) A vehicle suspension comprising a primary suspension of any type having a constant flexibility, together with a secondary suspenson of variable flexibility, is characterized by the secondary system comprising one or more relatively short powerful coil springs acting in tension, compression or both, one end of each spring being pivoted to a non-suspended vehicle part and the other end to a suspended part. the lattter end being guided through a right or arcuate path whose length is a substantial proportion of the length of the spring, the arrangement being such that when the vehicle carries no load the primary suspension bears most of the weight and the secondary suspension has a comparatively high flexibility, whereas under load, the secondary suspension bears a substantial part of the weight and its flexibility decreases with increasing load. The action of the secondary suspension may oppose that of the primary suspension throughout its range of movement, or the two systems may be in opposition under small loads and additive under heavier loads. As shown in Fig. 1, the front axle is supported by a normal leaf spring 5 of constant flexibility, and a compression coil spring 10, pivotably connected to an extension 8 of the fixed steering pin and to a bracket on the frame member 6. Equal vertical displacements of the wheel 2 result in progressively increasing lengthening of the coil spring, which thus has a variable flexibility. The combined system may be given different characteristics by varying the amount of initial compression of the spring 10 in the no-load position; this may, if desired, be so chosen that the spring 10 is no longer under compression for a given axle deflection, and further deflection places it under tension. In such a case, the pivotal mountings for the spring are preferably provided with rubber bushings, and telescopic guiding members provided within the spring to keep its ends aligned. Fig. 3 shows the arrangement applied to a vehicle axle of the type which the axle box 16 is guided in vertical guides 21. A pair of springs 10 are provided between the axle box and brackets 24 on the vehicle frames to provide the variable flexibility, a normal leaf spring 17 providing a system of constant flexibility. Fig. 4 shows a rear axle 32 supported by a normal leaf spring 29 of constant flexibility and a coil spring 34 providing variable flexibility. Fig. 12 shows the arrangement applied to an independent suspension, the whole being supported by a coil spring 37 of constant flexibility and another coil spring 38 connected to the top link at M and to the frame at Q so as to provide variable flexibility. Specification 644,851 is referred to.

Abstract: A method of manufacturing masses of metal particles having an average size of 10 microns or less, by submitting masses of substantially equally small sized particles of metal oxide to the action of a reducing agent to reduce the oxide to metal, which comprises mixing with the mass prior to the reduction, a carbohydrate substance which remains in solid form up to a temperature of at least 350 DEG C and which volatilises at temperatures about that at which the oxide softens to leave no residue other than the oxide and/or metal reduced therefrom.  The carbohydrate may be a starch containing substance, e.g. starch itself, and is preferably used in such amounts that when mixed with the oxide, the oxide particles are substantially surrounded by the carbohydrate.  Starch may be used in amounts of at least 20 per cent by weight of the mixture, which is heated in air, prior to reduction, at a temperature below the reducing temperature of the oxide to cause destruction of the starch and its removal from the mass.
