Title: Improvements relating to the preparation of methyl aryl silicones
IPC: C07F7/08
Filed: 1941-04-24
Abstract: 548,911. Resinous organo-silicon compounds. BRITISH THOMSON-HOUSTON CO., Ltd. April 24, 1941, No. 5294. Convention date, April 27, 1940. [Class 2 (iii)] Resinous methyl aryl silicones are obtained by hydrolysing and then dehydrating a methyl aryl silicon dihalide in which the aryl radical is non-halogenated. Products having a particular ratio of total methyl and aryl groups to silicon may be obtained by admixing various dihalides before hydrolysis or by admixing separately hydrolysed products before dehydration ; alternatively, various silicones may be admixed by grinding in solid form. Dehydration is effected by heating. Initial products are liquids which are converted to solid masses by further heating. In an example methyl and phenyl magnesium bromides are reacted, in ether solution, with silicon tetrachloride to form the methyl phenyl silicon dichloride which, after decanting from magnesium salts, was hydrolysed by pouring on to cracked ice ; after washing with water the ether and part of the water were removed by distillation, toluene was added and the solution boiled for some hours to yield a viscous liquid polymer which, upon further heating, was converted to a solid. The liquid and solid products may be applied as coating compositions or compounded with other materials as described in Specifications 542,655 and 544,143.

Title: Applicators and Containers for Liquids
Inventor: MELOCCHI MARIO
IPC: A45D40/26
Filed: 1967-02-03
Abstract: 1,179,724. Brush and container combinations. M. MELOCCHI. 3 Feb., 1967 [4 Feb., 1966], No. 5380/67. Heading A4K. [Also in Divisions A5 and B4] An applicator for fluid cosmetics incorporating a brush member which is insertable in a bottle or fluid reservoir comprises a hollow outer tube 31, on inner member 7 which is attached at one end to one end of the tube, the other end of the inner member carrying the brush 28, an intermediate sleeve 32 concentrically positioned and axially slidable in the inner member, resilient means such as a spring 35 biassing the intermediate sleeve towards the brush carrying end of the inner member and co-operating stop means on the inner member and the sleeve to limit the movement of the sleeve towards the brush. In use the inner member with the brush is inserted into the tapered neck 4 of the bottle 1, the sleeve subsequently being moved telescopically back into the outer tube 31 against the spring 35 so that only the brush and inner member are immersed in the fluid. Upon retraction of the brush the sleeve is moved by the spring to cover the inner member. The sliding action of the sleeve along the inner member serves to protect the fingers of the user from contact with any fluid which may remain on the inner member after the insertion of the inner member and brush in the bottle. Within the bottle means are provided to wipe the surface of the inner member, to smooth the brush and to remove surplus fluid from the brush as the latter is withdrawn from the bottle. The means includes a helically grooved resilient member 12 which may be of one piece or formed from a stack of washers located in the portion 8 of the bottle member together with a rubber member 21 positioned axially of the member 12 which is formed with two conical ports 25 and 26 separated by a partition 23 and having a central hole for the passage of the brush and member 7. The applicator and bottle may be connected by threaded portions to form a cylindrical unit.

Title: Improvements in and relating to carburettors
IPC: F02M25/07
Filed: 1965-02-08
Abstract: 1,097,758. Spray carburetters. REGENTS OF UNIVERSITY OF CALIFORNIA. Feb. 8, 1965 [Feb. 19, 1964], No. 5389/65. Heading F1B. A carburetter comprises a mixing chamber in which the entering air is set into rotation by inclined vanes 104, the fuel being injected into the air through a nozzle 64. The mixing chamber 32 is heated by exhaust gases which enter at 94 and flow through a jacket 92 and through orifices 100 to mix with the air flowing towards the inlet end 44 of the mixing chamber 32. The fuel in nozzle 64 is atomized by pressurized air fed by a pump 81 to chamber 76, the pressurized air also being fed through a pressure control valve 150 to the float chamber 65. A needle valve 70 - the fuel nozzle is controlled in accordance with the position of throttle valve 86, the throttle valve operating means (168) Fig. 2 (not shown), having a resilient lost motion device (174) which during acceleration delays the throttle movement slightly to enrich the mixture. A flap 110 controlling the flow to the exhaust jacket 92 is also actuated from the throttle control linkage and is arranged to be closed at idling and high power. The valve 150 is controlled by intake manifold suction acting upon diaphragm 144, whereby the pressure in chamber 65 is a maximum at high power and is reduced as the intake manifold suction increases. A throttle 183 in the pipe 138 leading to the intake manifold delays the effect of suction on the diaphragm 144 and hence enriches the mixture during acceleration and makes it leaner during retardation. A pressure switch 184 also operates a solenoid 120 to close a fuel shut-off valve 116 during over-running. A by-pass valve 186 is energized from the starter motor circuit 188 to supply fuel directly from the fuel supply pipe 126 to the nozzle at starting. Crankcase gases may be fed to the mixing chamber through inlet 190. In a modification, Fig.6 (not shown) the atomizing air pump is omitted and the fuel atomized by feeding to chamber 76 vapour from a portion of the fuel passed through an exhaust heated vapourizer 214. In a further modification Fig. 7 (not shown), the atomizing air pipe 80 is connected to the carburetter air intake and the throttle valve 86 is situated upstream of the mixing chamber so that the atomizing air is drawn in by the suction in the mixing chamber.

Abstract: 1503031 Isotope separation F M DEVIENNE 21 Feb 1975 [21 Feb 1974] 5826/75 Heading HID A method of separating isotopes comprises producing a beam of ions of a compound containing the isotopes from a source 6 and accelerating the beam through a series of collision boxes 12 to 16 which contain a neutral target gas such as argon or helium causing dissociation of the ions into ion fragments some of which are distinguished by containing the different isotopes and maintaining the collision boxes at a potential such that ions containing one of the isotopes are preferentially trapped within the boxes and condense on the walls. The other ion fragments are caused by electrostatic deflectors 19 to 23 to condense on a slidably removable liner 11. The method is used for separating uranium isotopes and the initial compounds can be iodides, bromides or chlorides of uranium. The condensation surfaces of the apparatus are cooled. The collection of ion fragments can be improved by the provision of auxiliary collectors at the exits of the collision boxes, Fig. 2(b) (not shown).
