They are prepared by copolymerizing the disiloxane <FORM:0757855/IV(a)/2> (see Group IV (b)), with a diorganosiloxane, preferably in the presence of an alkali metal hydroxide catalyst.  Suitable diorganosiloxanes are dimethyl-, phenylmethyl-, stearylmethyl-, vinylmethyl-, divinyl-, alkylphenyl-, diphenyl-, xenylmethyl-, ditolyl-, bromoxenylmethyl-, bistrifluorotolyl- and chlorophenylmethylsiloxane.  In the examples (3) the above disiloxane is heated with octamethylcyclotetra siloxane for 2 days in the presence of KOH to give a mixture of compounds of the first formula in which R1 is methyl and n is 1, 2 and 3, and a distillation residue of higher siloxanes; (4) the disiloxane is similarly copolymerized with phenylmethylsiloxane (mixture of cyclic trimer, tetramer and pentamer), with methyl vinylsiloxane, and with dichlorophenylmethylsiloxane) mixture of cyclic trimer, tetramer and pentamer).ALSO:The invention comprises silylethylpyridines of the formula <FORM:0757855/IV(a)/1> where R is methyl or phenyl, and siloxanes the formula <FORM:0757855/IV(a)/2> where n is 0 or an integer and R1 is a monovalent hydrocarbon or halogenated aryl hydrocarbon radical.  The silylethyl pyridines are prepared by reacting 2-picolyl lithium with chloromethyltrimethylsilane or chloromethylphenyldimethylsilane.  The disiloxanes (i.e. compounds of the above formula when n = 0) are prepared by reacting the silylethyl pyridines with conc-sulphuric acid, treating with water and making alkaline with an alkali metal hydroxide.

Title: Improvements in or relating to vibrating strain gauges
Inventor: CRITCHLEY OCTAVIUS HUNT
IPC: G01L1/10
Filed: 1958-08-25
Abstract: 924,381. Vibrating wire strain gauges. COAL INDUSTRY (PATENTS) Ltd. Aug. 4, 1959 [Aug. 25, 1958], No. 27198/58. Class 40(1). In a vibrating wire strain gauge for embedding in a structure fabricated from concrete or similar material the unit is constructed in such a manner that its strength matches that of the structural material that it displaces. Wire W, Fig. 2, is contained in tube 1 and is clamped in hub 2 by screws 8 and in hub 3 in clamping arrangement 13 which is axially movable in hub 3 under the action of nut 20 in order to adjust the initial tension of wire W. The wire is set into vibration and its vibrations sensed by coils 28 on permanent magnet core 27. The dimensions and material of tube 1 are chosen according to the formula: where r = radius of the tube t = thickness of tube wall Modulus of elasticity of tube material and E = Modulus of elasticity of material in which gauge is embedded. In further embodiments the gauge is shown embedded in sections of structural material, holes having been cast into the sections, in order to permit access to the tension adjusting means through cap 25, Fig. 3 (not shown). A further form of gauge unit, Fig. 4 (not shown), uses a large section tube in place of tube 1 which completely encloses the coil and magnet assembly thus dispensing with the need for box 26 in the centre of the tube which tends to affect the modulus of elasticity of the composite arrangement. The Specification contains a reference to temperature compensation of the gauge by suitably choosing the temperature coefficients of expansion of the wire and the tube relative to the structural material in which the gauge is embedded.

Lever- and spring- actuated pumps; buffers, springs, and the like. - The reciprocating pump ing element of a pump is actuated from a cam shaft or other moving part by means capable of imparting only intake movements at normal speeds, but capable at higher speeds of effecting delivery strokes. A diaphragm pump is shown in which the delivery stroke is normally effected by a spring 15 acting on the diaphragm 3; the intake stroke is effected by a cam-shaft-operated rocking lever 7 which is connected to the diaphragm stem by a lostmotion device consisting of a piston 48 and cylinder 47 with air ports 55, 56.

Title: Improvements in method of and apparatus for controlling the flow of fluids

Abstract: 392,529. Fluid-actuated valves. BAILEY METER CO., 1050, Ivanhoe Road, Cleveland, Ohio, U.S.A. Oct. 9, 1931, No. 28081. Convention date, Oct. 11, 1930. [Class 135.] Valves controlled by pilot or relay valves.-A method of controlling a number of flowing fluids comprises determining the ratio of the rates of flow and the total of the rates of flow and con. trolling one of the fluids in accordance with variations in the ratio and another of the fluids in accordance with variations in the total. The fluids may be gases of different calorific values for supply to a furnace or fluids to be mixed in a chemical process. As shown, blastfurnace gas and coke-oven gas are supplied through conduits 1, 2 and mix in a conduit 3. Dampers 4, 7 in the conduits 1, 2 are controlled by pistons 5, 8 in cylinders 6, 9 connected respectively through stabilizers 22, 27 with pilot valves 21, 29 controlling a supply of hydraulic fluid. A flow meter 12 of the differential pressure gauge type responsive to variations in the flow of the blast furnace gas past an orifice 10 in the pipe 1 has a stem 15 connected through levers and links 36 .. 40, a floating lever 41 and links 42, 43 with the pilot valve 21 governing the valve 4, while a similar flow meter 16 responsive to the flow of coke-oven gas is connected by stem 19, levers and links 44 .. 47, floating lever 48, link 49, and lever 35 to the pilot valve 29 governing the valve 7. The floating lever 48 is pivoted at one end to the rod 37 and the lever 44 is connected by a rod 50 to the floating lever 41. The floating lever 48 being moved additively by the two flow meters moves the pilot valve 29 in accordance with the total of the rates of flow while the floating lever 41 acted on differentially by the flow meters moves the pilot 21 in accordance with the ratio of the flows. One end of the lever 46 is pivoted to an adjusting device A whereby its pivot may be raised or lowered and clamped in the adjusted position, this adjustment varying the total flow. The fulcrum B of the lever 38 is adjustable along the lever to vary the ratio between the rates of flow of the coke-oven and blast-furnace gas. In the case of partial or complete failure of the blast-furnace gas the damper 4 will be fully opened and the damper 7 opened to supply sufficient coke-oven gas to maintain the heating value constant. The stabilizing devices 22, 27 each comprise a piston 30 in a cylinder 31 connected by a rod 34 with the ends of the beams 35, 43 of the pilot valves respectively. If the pilot valve 29 is displaced downwardly pressure fluid is admitted to the cylinder 31 under the piston 30 and thus tends to raise the pilot valve, preventing hunting.

Title: Improvements in or relating to cracking hydrocarbon oils
IPC: C10G9/36
Filed: 1934-10-01
Abstract: <PICT:0425953/III/1> Relates to vapour-phase cracking of hydrocarbon oils with the aid of heated carrier gas, e.g. as described in Specification 317,508, [Class 32], and consists in simultaneously cracking naphtha and gas oil or oil of higher specific gravity to produce motor fuels by feeding a mixture of such oils to a vaporizer, superheating the vapour and passing it to a cracking chamber with the necessary quantity of heated carrier gas.  The amount of naphtha may be up to 50 per cent of fresh feed gas oil, the vapours being superheated to 850--965 DEG  F. and cracked at a temperature of 950--1050 DEG  F.  As shown, naphtha is fed from a tank 41, together with liquid condensate from a rectifier 22, to a vaporizer 40 and the vapour separated in a flash drum 42 is passed through a superheater 44 and pipe 45 to the reaction chamber 14 where it is mingled with heated carrier gas from a hot blast-stone 50.  From the chamber 14 the reaction products pass to a scrubber 12 fed with changing stock from a tank 10.  The hot oil residue from the scrubber 12 is removed through a pipe 17 and, after recovery of heat in heat exchangers, all or part of the oil is returned to the scrubber by the pipe 19.  From the scrubber the vapours pass to rectifier 22 where the ends heavier than motor fuel are removed, the temperature being regulated by cycling part of the residue through a cooler 24.  Uncondensed vapours pass to a condenser 28 leading to an accumulator 29, the uncondensed vapour passing to an absorber 34 from which stripped gas passes to a gas-holder 36. Gas is admitted to the stoves 50 by a pipe 47.
