Abstract: An organosilicon composition consists of 1 to 75% by weight of a phenyl containing siloxane resin which is a copolymer that consists essentially of phenyl and methylsiloxane units and has a phenyl to silicon ratio in the range 0.1:1 to 1:1, a methyl to silicon ratio in the range of 0.6:1 to 1.1: 1 and the total of the phenyl and methyl to silicon ratio being in the range of 0.8: 1 to 1.8: 1, 0.1 to 10% by weight of an alkyl silicate; 0.01 to 2% by weight of a chlorosilane, the balance being a non-halogenated solvent.  The copolymer may consist of phenyl and methylsiloxane units selected from: CH3SiO3- 2, (CH3)2SiO CH3(C6H5)SiO, C6H5SiO3- 2\t and (C6H5)2SiO siloxane units.  The resin can also contain some SiO2 units and R3Si end-blocking units where R is methyl or phenyl.  The aryl silicates can be those of general formula Si(OR)4 and Si(OR1OR)4 in which R is an alkyl radical and R1 is an alkylene radical of 2-4 C.  Examples are ethyl orthosilicate, n - propylorthosilicate, ethyl polysilicate, (C2H5OCH2CH2O)4Si, methyl polysilicate, octylsilicate or butylpolysilicate.  The chlorosilanes are those of formula RnSiCL4- n where R is a hydrocarbon radical of 1-18 C and n is 1, 2 or 3. Examples are methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, methylvinyldichlorosilane, methylethyldichlorsilane, ethylheptyldichlorosilane, ethyltrichlorosilane and triethylmonochlorosilane.  Suitable non-halogenated solvents are toluene, benzene, xylene, naphtha, mixed octanes, acetone, diethylether, methylisobutylketone.  It is essential that the siloxane resin and non-halogenated be mixed together first, the alkylsilicate and chlorosilane may then be added in any order. In a typical example (1) a copolymer consisting of (CH3)2SiO, CH3SiO3- 2 and C6H5SiO3- 2 units was mixed with acetone. Ethylorthosilicate and methyl trichlorosilane were added to the mixture.  The composition was used as a primer composition for bonding a silicone rubber to various surfaces, e.g. glass, aluminium, stainless steel, copper and brass.

Abstract: 1,105,778. Change-speed control. BORG WARNER CORPORATION. 16 Nov., 1965 [23 Nov., 1964], No. 48660/65. Headings F2C and F2D. In order to cushion gear changing in a hydromechanical vehicle transmission a clutch arranged in series with the hydraulic coupling is disengaged upon a gear shift to break the drive through the coupling, the subsequent reengagement of the clutch being automatically regulated. In the system shown a disc clutch D is connected to the impeller or the turbine of a three-element torque converter C, Figs. 2 and 3 (not shown) and the forward and reverse ratio clutches E of the mechanical gear-box are controlled by a manual selector valve 71 with a rotary arm 73 connected to a pressure supply line 70 and movable over ports 74 connected to clutch supply lines 79. A control valve unit comprises three regulator valves 81, 82, 83 in cascade, the first supplying liquid from line 70 to clutch D through a line 101. A diverter valve 117 is normally held in the position shown to allow pressure liquid from line 70 to pass to the underside of a piston 120 bearing against the underside of the second valve 82 through a loading spring 103 to maintain the clutch supply pressure in line 101. During a gear change the selector arm 73 passes over one of a series of ports 76 between the ratio clutch ports 74 and connected by a line 77 to the underside of diverter valve 117 which is thereby raised against a spring 116a to out off communication between pressure line 70 and piston 120 so that valve 82 operates to disengage the clutch D and thus break the drive to the converter impeller or turbine. Upon completion of a gear shift the rate of return of valve 117 to its normal position, and hence the rate of reengagement of clutch D, is automatically regulated by orifice valves 122, 126 located in line 77 and between valve 117 and piston 120 respectively. The third valve 83 operates to maintain the supply of liquid to the torque converter.
