Title: Improvements relating to pumps
Inventor: SELWOOD WILLIAM RICHARD
IPC: F04B43/00
Filed: 1962-08-18
Abstract: 993,895. Reciprocating pumps. WILLIAM SELWOOD Ltd. Nov. 15, 1963 [Aug. 18, 1962], No. 31776/62. Addition to 786,290. Heading F1A. The pump described in the parent Specification is improved by providing the diaphragm 51, Fig. 5, with a hinge portion 60, of concertina or folded shape so as to facilitate downward flexure of the peripheral margin 54 when an excessive working pressure arises in the upper working chamber. The pump and an I.C. driving engine 16a, Fig. 1, are mounted on a frame 10 which has adjustable jacking legs 30 and wheels 37. The pump component 19 is secured to the working chamber by bolts 23 to permit access to chamber 17. The legs may be moved by a manually-operated or power-driven screw or hydraulic mechanism. Hose retaining members 75 formed on each leg may be adjustable vertically of their associated legs. Shaft 45 driven by a belt and pulley or chain and sprocket reciprocates the diaphragm 51 through an eccentric sheave 44. During normal operation the downward movement of the diaphragm 51 forces liquid through gap 73 and upward movement causes the peripheral margin 54 to seat whilst the centre diaphragm part expels liquid from the upper chamber part 17. If the pressure in chamber 17 becomes too high, the margin 54 is folded downwardly. The diaphragm 51 may be of acrylonitrile and may be reinforced at the peripheral margin with an annular metallic insert.

Abstract: 1,163,853. Rotary wing aircraft with aircushion undercarriage. VLM CORP. 11 July, 1967 [13 July, 1966; 16 June, 1967], No. 31799/67. Headings B7G, B7K and B7W. A rotary wing aircraft 10 (which may have a spherical fuselage) comprises aerofoils 16, 302 (which may be carried by wing members 70, 72) movable along annular tracks 12 and 14, 303 and 306 the outer tracks supporting the outer ends of the aerofoils which are driven by fluid pressure (e.g. by air jets from nozzles supplied from a compressor 56 via a reservoir 54 and pipes 26 or 32 and 40 or 42, impinging on a row of blades in the outer ring member 72). The exhaust air from these jets may pass out through jets 44 adjusted to prevent, or adjustable to control yaw motion. The ring members 70, 72, 328 may be supported in the tracks 12, 14, 303, 304 by air bearings. The horizontal motion of the aircraft 10 is controlled either by the tracks 12 and 14, Fig. 1, being held rigidly by pipes 26 and 32 in a plane tilted by jacks 20 and 21 or by blades 302, Fig. 17, being pivoted so that the planes containing them and the pipes 305 are free to cone, the blades having adjustable cyclic pitch change. Blade pitch control of the latter form, Figs. 19 and 21, comprises in the blade 302, a tube 350 having a cam slot 351 engaged by a follower 352 attached to a mass 353 slidable radially in the tube. The mass 353 is restrained from radially outward movement by a spring 354 in a cup 355 restrained by a cable 340. Rotor speed increase compresses the spring 354 increasing the collective pitch. The cable 340 passes through the blade to a ring 341 rotatable on an air bearing about a ring 342 which can be made eccentric of the aircraft by differential inflation of four balloons 348 causing cyclic pitch change. There may be a parachute in the top of the fuselage. The aircraft may have an air cushion undercarriage comprising a toroid 64, Fig. 3, containing a space below the fuselage 18 filled with air from the reservoir 54. The toroid 64 may be inflated to act as a buoyancy tank and may be assisted in this by a further inflated toroid (shown dotted).

Title: Improvements in or relating to a process of treating tobacco
IPC: A24B15/24
Filed: 1956-10-19
Abstract: Tobacco, which has been rendered partly or wholly neutral, i.e odourless and flavourless, by a plurality of successive water extractions at progressively higher temperatures, is saturated with one, some or all of the fractional extracts obtained by this treatment or by like treatment of other tobacco.  The invention is directed primarily to the alteration of Philippine native tobacco to be of lighter colour, milder aroma and less bitter taste and thus to simulate American Virginia tobacco whilst being resistant to moulding and of less nicotine content than ordinary cured tobacco.  In one process, cured and cut native tobacco is soaked in water for thirty or forty minutes at, successively, room temperature, 60 DEG  C., 80 DEG  C. and 100 DEG  C., the tobacco being strained after each soaking and finally dried at 100 DEG  C. in a rotating drier.  The extractions produced by the strainings are of progressively more bitter taste and stronger aroma.  The dried neutralized tobacco is bleached with hydrogen peroxide, containing pure hydrogen and acetanilide, is dried as before and cooled, and is then saturated for two hours with an extract formed of a mixture of fractional extractions produced from Virginia tobacco dust in a similar manner to that described for the native tobacco.  The saturated tobacco is finally dried at 60 DEG  C. in a rotating drier.  The Virginia tobacco extract may contain glycerine, yellow-orange colouring matter, wines, liquors, molasses, honey, vanilla extract and aromatics.  In another process, no Virginian tobacco is used, the neutralized but unbleached native tobacco being saturated with a mixture of the first and second only of four successive fractional extractions of native tobacco dust.  In a further process, the neutralized but unbleached native tobacco is saturated with a mixture of extracts of Virginian and Turkish tobacco dust.  In a modified process, native tobacco partly neutralized by the removal of the first and second only of four possible fractional extractions is saturated with a mixture of the third and fourth of four fractional extractions of native tobacco dust.  Reference is made to the application of the invention to the treatment of Virginian Bright, Burley, Maryland and Perique tobaccos.

Title: Improvements in or relating to oxidation of aromatic hydrocarbons
IPC: C07C409/10
Filed: 1948-12-16
Abstract: Hydroperoxides of the formula Ar-CR1R2-OOH, where Ar is an unsubstituted aryl radical and R1 and R2 are alkyl groups, are used as catalysts for the polymerization of vinyl, vinylidene and vinylene compounds, e.g. in the copolymerization of butadiene and styrene.ALSO:Compounds of the formula Ar-CHR1R2 are converted into the corresponing tertiary hydroperoxides by passing an oxygen-containing gas through them in the liquid phase in the presence of 0.15-0.8 per cent (preferably 0.2-0.6 per cent) of a heavy metal compound as catalyst; Ar is an unsubstituted aryl group and R1 and R2 are alkyl groups.  Suitable starting materials are cumene, sec-butyl benzene, isopropylnaphthalene and other hydrocarbons derived from benzene, naphthalene, anthracene or phenanthrene where the groups R1 and R2 are methyl, ethyl, propyl, isopropyl or any of the butyl radicals and may be the same or different.  If the starting material is a solid it must be dissolved, e.g. in benzene.  The oxygen may be pure or diluted, e.g. as air. The catalyst may be an oxide, hydroxide or organic acid salt (soluble in the reaction mixture) of manganese, cobalt, lead, iron, nickel, copper, vanadium, chromium or mercury.  Suitable acids whose salts may be employed are phthalic (monobutyl ester), linoleic, naphthenic, acetic and resinic, e.g. abietic, dehydroabietic, di- and tetra-hydroabietic and pimaric.  The catalyst may contain more than one metal, and a peroxide such as one of the products of the invention may be added as initiator.  The reaction temperature is preferably 40-70 DEG  C. at atmospheric pressure or up to 140 DEG  C. at higher pressures, e.g. up to 500 lb./square inch.  The reaction mixture is worked up by filtration, washing with alkali and either low-pressure distillation or precipitation with concentrated sodium hydroxide solution.  Examples show the oxidation of cumene and isopropylnaphthalene, there being obtained as by-products dimethylbenzyl and dimethylnaphthylmethyl alcohols respectively. Specifications 309,005, [Class 2 (iii)], and 665,897 are referred to.
