Patent GB-638264-A (GB)
Title: Improvements in mooring gear for flying boats and the like
IPC: B64C35/00
Filed: 1948-06-28
Abstract: 638,264. Control of several motors. SAUNDERS-ROE, Ltd., and SAUNDERS, P. E. June 28, 1948, No. 17311. [Class 38 (iii)] [Also in Group XXXIII] A mooring attachment for a flying boat or other water-borne vessel comprises a housing 12 mounted within the hull 28, a pair of spaced prongs 16, 17 in the housing movable between a normal retracted position and a projected position, the prongs converging downwardly when projected, mechanism operable under manual control to move one of the prongs into the projected position, and a trigger 23 projecting beneath the housing and adapted, when contacted by an underwater cable 24 approaching the projected prong, to effect automatic movement of the other prong to the projected position and thereby trap the cable between the prongs. In the arrangement shown, the housing 12 is free to rotate except during the cable picking-up operation, while the prongs 16, 17 are operated by electric screw-jack type actuators and are raised simultaneously to disengage the cable. The sequence of operations is as follows: (1) To project the rear prong 17 the pilot moves a switch 35 to the " Lower " position, closing the contacts C3 of a relay R3 and energizing the field winding RFL of a motor MR. When the prong is fully projected, limit switches RL1, RL2' operate to stop the motor. (2) Engagement of the cable 24 with the lower end 23 of a trip-rod 21 closes a microswitch C, thereby closing the contacts C1 of a relay R1 and energizing the field winding FFL of a second motor MF to project the forward prong 16. Limit switches FL1, FL2 operate when the prong is fully projected. (3) To release the cable, the pilot moves the switch 35 to the " Raise " position, to close the contacts C2, C4 of relays R2, R4, and energize the field windings RFR, FFR of the motors MR, MF, and thus retract both prongs. When the prongs are fully retracted the motors are stopped by the limit switches RL1, RL2, FL1, FL2. The positions of the prongs are shown by indicators 44, 45, 46, 47. The top of the mooring housing 12 carries a gear-wheel 25 engaged by a pinion 26 of a rotary actuator 27 ; normally the pinion is free to move relatively to the actuator, but can be locked thereto by a clutch operated by a solenoid 29. During the picking-up operation the solenoid 29 is energized, thus preventing rotation of the housing 12, but when both prongs are fully projected the solenoid is de-energized and the housing is free to rotate. During flight the housing 12 is self-aligning in order to minimize drag; if it is displaced from this position a cam projection 30 allows switches A1, A2 to close, to energize the field winding F of a third motor M, which restores the housing to the aligned position. If the housing moves out of alignment during the picking-up operation the circuit of the motor MF is broken, motor M operated, and the circuit of the motor MF is restored when the housing returns to its position of alignment. Specifications 575,723, 575,919, 603,030 and 613,157, [all in Group XXXIII], are referred to.

Patent GB-1505641-A (GB)
Title: Process of preparing a filler composition for paper
IPC: D21H17/69
Filed: 1974-04-19
Abstract: The production of a filler material suitable as an additive to pulp starts from particles based on an inorganic material and from synthetic polymeric resins. An aqueous suspension of particles having a positive zeta potential is mixed with an anionic latex of the resin. The particles are thus coated with a resin layer. The ratio of the negative and positive charges of the particles based on an inorganic material in the suspension and of the resin in the latex is adjusted during mixing in such a way that essentially all the resin particles are bound to the surface of the inorganic particles. The inorganic particles can, for example, be calcium carbonate; the resin is a styrene/butadiene copolymer. The filler material produced in this way can be used in paper manufacture as a cellulose pulp substitute. The process can be carried out during the actual paper manufacture.

Title: Improvements in electron image amplifiers, and methods of operating the same
IPC: H01J31/42
Filed: 1936-06-23
Abstract: 471,448. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. June 23, 1936, No. 17418. Convention date, July 6, 1935. [Class 39 (i)] An electron image is projected on an insulating surface to fix charges thereon corresponding with a linear area of the electron image, and the charges are successively neutralized by a uniform electron stream and the neutralizing energy sets up a signal train. As shown, an electron image from a photo-electric cathode 2 is projected on to a linear charge-storage electrode consisting of a tungsten rod 7 having a glass coating 9, the anode 5 being provided with an aperture to allow the passage through it of the electrode 7, 9. The electron image is focused by a coil 21 and scanned by a coil 25 supplied from a low-frequency source. An electron gun 17, 18, mounted in a side tube, has deflecting electrodes 19, connected with a high-frequency oscillator, whereby the beam from the gun is traversed along the electrode 7, 9. The rod 7 is connected through an output resistance. In one method of operation, the photo-electrons are accelerated to such a speed that secondary electrons are emitted from the coating 9, leaving positive charges which are discharged by the beam from the gun. Surges of current are set up in the rod 7 corresponding with the capacity between the rod and the surface charges. In another method, the potential on the anode 5 is such that secondary electrons from the coating 9 are not produced by impact of photo-electrons, but are produced by impact of the beam from the gun.

Title: A process for preparing products suitable for baby nutrition
IPC: A23C21/06
Filed: 1948-06-29
Abstract: Baby food is made by drying to a product containing not more than 40 per cent of water, e.g. by spray drying at 60 DEG -75 DEG C., a dispersion of casein or a casein-containing substance, a fat or oil or fat- or oil-containing substance, and whey which has been treated to reduce its ash content to less than 4 per cent, based on the dry matter, and contains the whey proteins in a soluble state, or by mixing substances containing casein and substances containing a fat or oil with such a whey which has been dried to a powder. Preparation of the whey may be effected by dialysis, preferably after precipitation of the calcium by the addition of sodium or potassium oxalate or after exchange of the calcium against sodium by treatment with a zeolite, or by electrodialysis as described in Specification 637,425.  The fats or oils preferably contain saturated and unsaturated fatty acids in the same proportion as in the fat of human milk.  Vitamins, hormones, and trace elements, e.g. iron, zinc, copper, may be incorporated. With milk or cream, vitamins D2 and D3 may be produced preliminarily by ultra-violet irradiation.  Agents such as phospholipoids, e.g. lecithin, may be added to promote dispersion of the fat or oil.  Addition of vitamin C prevents rancidification of the fat or oil.  Saccharose, dextro-maltose, or fructose may be added.  Examples are concerned with drying mixtures of whey with: cow's milk and cream; cream; cream powder, vitamin A and vitamin C; cow's milk, cream and vitamin A treated with u.-v. light, and vitamin C; vitamin C and cream; cream, vitamin C, vitamin A, sodium chloride, ferrous sulphate, cupricchloride, zinc chloride and potassium iodide; lecithin, cow's milk or skimmed milk, palm oil or mixtures of palm oil with coconut or linseed oil, vitamins A and C, sodium, iron, copper and zinc as sulphates, chlorides or lactates, and sufficient sodium citrate and citric acid to produce pH 7, or, if pH 4.5 is required, sufficient citric acid or lactic acid.  The Specification as open to inspection under Sect. 91 comprises also the preparation of a food of any water content by mixing whey having an ash content of less than 4 per cent, based on the dry matter, with any foods, exemplified by proteins and esters of fatty acids.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to injectors for internal combustion engines
IPC: F02M61/04
Filed: 1935-06-18
Abstract: 463,130. Liquid - fuel injection devices. SOC. GENERALE DES CARBURATEURS ZENITH. June 18, 1935, No. 17529. Void. Convention date, June 19, 1934. [Class 7 (iii)] In an injector in which fuel is admitted through a pipe 19 along the axis of the injector, provision is made for adjusting the tension of the closing-spring 12 of a valve 8 opened by fuel pressure, or for adjusting the setting of a fixed needle without dismantling the injector. The fuel passes from the pipe 19 through passages 23, 24, 28 and through slots 32 in the valve to a chamber 30. An opening 37 is formed in the wall of the injector body 1 opposite the seat of the spring, and the pressure of the spring is adjusted by inserting a tool through the opening 37 into one of a series of slits 38 in a member 34 against which the spring bears, and screwing or unscrewing it into a plug 6. After adjustment the member 34 is locked by inserting a cotter-pin through the opening 37 and one of the slits 38 into a hole in the opposite side of the body. In Fig. 3, the spring 12 bears against a spindle 43 which passes through slots 44 in the body 1, and is adjusted by a nut 46. In a further modification, a head integral with a fixed needle is adjusted as described with reference to Fig. 1, to control the size of the injection orifice.
Patent GB-912976-A (GB)
Title: Halogen substituted alkylbenzoic acids
IPC: C07C63/70
Filed: 1959-05-22
Abstract: The invention comprises chloro- and/or bromo-substituted 2-alkyl benzoic acids of the general formula <FORM:0912976/IV (b)/1> wherein R is an alkyl group, X is a chlorine or bromine atom and Y is a chlorine, bromine or hydrogen atom.  In an example, orthoxylene is chlorinated with gaseous chlorine, in the presence of iron filings, to produce a mixture of isomeric trichloroxylenes.  Chlorination is then effected in a side-chain to give the corresponding trichloro - monomethyl - benzyl chlorides, which are converted into the acetates by reaction with sodium acetate.  Finally, the mixture of isomeric esters is treated with concentrated nitric acid to obtain 2-methyl-3,5,6-trichlorobenzoic acid mixed with other isomers. The mixed acids may be esterified with an aliphatic alcohol; and the benzoate esters may then be separated, and subsequently hydrolysed with HCl to form the individual benzoic acids.  2 - Methyl-tetrachlorobenzoic acid may be prepared in a similar manner. In a second example, propylbenzene is monobrominated to form a mixture of o- and p-bromo-propylbenzenes, which are separated by distillation.  Nuclear trichlorination of the ortho-bromo propylbenzene produces a mixture of isomers including 2-bromo-3,4,6-trichloro-propylbenzene.  By the Grignard reaction utilizing magnesium, followed by treatment with CO2 gas in the presence of H2O, the bromine atom is replaced with a carboxyl group thereby producing a mixture of isomeric acids including 2-propyl-3,5,6-trichlorobenzoic acid.  In a third example, dodecyl benzene is reacted with hydrochloric acid and formaldehyde, in the presence of zinc chloride, to form dodecyl-benzyl chloride, which is converted into the acetate.  The acetate is oxidized with nitric acid to obtain dodecyl benzoic acid, which is then chlorinated to form dodecyl-trichlorobenzoic acid or dodecyl-tetrachlorobenzoic acid. Various salts of these substituted benzoic acids are referred to; viz. those of sodium, potassium, ammonium, calcium, barium, dimethylamine, and mono-, di- and triethanolamine.  The esters and amides of the acids are also referred to.  All these compounds have herbicidal activity (see Group VI).ALSO:Herbicidal comprise a chloro- and/or bromo substituted 2-alkyl benzoic acid of the general formula <FORM:0912976/VI/1> wherein R is an alkyl group, X is a chlorine or bromine atom and Y is a chlorine, bromine or hydrogen atom, mixed with a solvent or a particulate solid.  The salts, amides and esters of the halo-substituted 2-alkyl benzoic acids may also be used in the herbicidal compositions.  The examples indicate the effectiveness as herbicides of 2-methyl-trichlorobenzoic acid as its dimethylamine salt and of 2-methyl-tetrachlorobenzoic acid as its sodium salt in dilute aqueous solutions, containing 1, 10, 100 and 1000 parts per million of herbicide (calculated as the acid), by means of tests carried out on seeds of buckwheat, cucumber, rape, oats, tomato and lettuce.

Patent GB-1039394-A (GB)
Title: Improvements in or relating to methods of producing fuel gas
IPC: C10K3/06
Filed: 1964-04-30
Abstract: Fuel gas is produced by hydrogasifying a liquid hydrocarbon at 1250-1400 DEG  F., using as source of hydrogen the gas mixture produced by catalytic steam reforming of the same liquid hydrocarbon (said mixture comprising H2, CO, CO2, CH4).  In a particular embodiment, naphtha, for example, and the hydrogen-containing product of steam reforming of naphtha are pre-heated to 1400 DEG  F., by combustion of recycled reformer naphtha and passed at 375 p.s.i.g. into a hydrogasifier. Steam is present or absent depending on whether excess in the reformer product has been removed. Exothermic hydrogasification occurs and the gaseous products are cooled by heat exchange with reformer naphtha (for recycle to the reformer) with steam (which is superheated to 448 DEG  F. and 400 p.s.i.g. and supplied to the shift converted following the reformer) with water (for superheating as above) and with fat oil, to a final temperature of 100 DEG  F.  The gaseous products are C1-C5 hydrocarbons, benzene, and toluene and have a heating value about 800 B.Th.U./ft.3  The aromatics are removed by countercurrent exchange with lean oil, which is then stripped and recycled, and the light hydrocarbons are withdrawn as product.  (1) Simultaneously, naphtha is heated to 750 DEG  F. by exchange with gaseous reformer product, mixed with steam (vaporized and superheated by the heat of the gaseous reformer products) and passed at 350 p.s.i.g. into the catalytic reformer.  A gas mixture containing CH4, CO, CO2 and H2 at 1400 DEG  F. and 300 p.s.i.g. is formed, cooled to 1215 DEG  F. by heat exchange with the feed, and introduced with steam (at 448 DEG  F., 400 p.s.i.g. as previously disclosed) into a shift converter wherein the CO content is reduced below 1.5% by volume. Some reformer product, sidestepping the converter, is cooled and recovered per se.  (2) The shift converter effluent after cooling is stripped of steam and either recycled to the hydrogasifier preheat furnace as the hydrogen-containing gas or withdrawn itself as product.  (3) Flue gases from the reformer superheat steam for recycle and after further cooling, are released.  The products (1), (2), (3) may be blended in any proportion to give a fuel gas with the required heating characteristics.  The feedstock is desulphurized before use in the process, for example as described in Specification 902,148.
