Title: Improvements relating to the production of cation-exchange materials
IPC: C01B33/46
Filed: 1945-12-17
Abstract: An alkali alumino-silicate cation exchange material is produced by mixing solutions of an alkali metal aluminate, an alkali metal silicate, and an aluminium salt yielding aluminium ions, e.g. the sulphate, in such proportions that in the final gel the molar ratio Al2O3/SiO2 is 1 : 1.5-4 and that the aluminium salt provides 5-20 per cent by mols of the Al2O3, heating the gel whilst maintaining it moist, and then drying.  The heating, which may be for 1 to 6 hours at between 95 DEG  C. and 50 DEG  C. renders the gel insensitive to drying, and may take place whilst the gel is in contact with the mother liquor; alternatively, the filter cake may be heated in a moist atmosphere, e.g. by introducing steam.  The dried gel after crushing and washing, may be treated with silver nitrate solution to produce silver alumino-silicate, which may be dried at 135 DEG  C. Specification 576,969 is referred to.

Abstract: 849,690. Automatic voltage control systems. GENERAL ELECTRIC CO. Ltd. Oct. 20, 1958 [Nov. 1, 1957], No. 34172/57. Class 38 (4). To prevent an A.C. machine 1 falling out of step, the excitation is increased by means of a magnetic amplifier when the phase angle between the rotor and rotating field exceeds a predetermined amount. The output from an A.C. permanent magnet generator 20 attached to the rotor is compared in phase with a voltage representative of the stator voltage across a resistor 19, the resultant voltage being applied together with a voltage from transformer secondary winding 10 through rectifiers 21, 12, respectively, to the signal winding 13 of a magnetic amplifier 14. The amplifier output is biased by a blocking rectifier 23 and a voltage derived from a rectifier 22, so that when the output exceeds the bias voltage a second control winding 7 assisting the normal control winding 6 of an automatic voltage regulator 5 increases the excitation of the machine. The magnetic amplifier may be of the auto-excited type.

Title: Manufacture of cyclic acetals of formaldehyde
IPC: C07D319/06
Filed: 1937-12-14
Abstract: 507,571. Cyclic formals. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Dec. 14, 1937, No. 34579. [Class 2 (iii)] Cyclic formals are prepared by reacting one mol. of an aliphatic mono-olefine, e.g. propylene or a butylene or a pentylene, with preferably about 2 mols. of formaldehyde (or its equivalent of a substance yielding formaldehyde, such as paraformaldehyde) in the presence of a strong mineral acid or a metal salt thereof having an acid reaction or an organic acid derived from a strong mineral acid, e.g. zinc chloride, hydrochloric acid, sulphuric acid, potassium or sodium bisulphate, phosphoric acid, phosphotungstic acid, benzene- or toluene-sulphonic acid. Aqueous formaldehyde may be used, and in the case of gaseous olefines pressure may be employed. Temperatures are suitably between room temperature and 150‹ C., but if hydrochloric acid is the catalyst the reaction must be carried out below 50‹ C. and be interrupted at an early stage. An indifferent organic solvent may be employed, e.g. hydrocarbons such as benzene, toluene or benzine, or halogenated hydrocarbons such as methylene chloride or dichlorethylene. The process may also be carried out continuously in a tube through which the olefine is passed in counter-current to an aqueous solution of formaldehyde in which the catalyst is dissolved; an organic solvent is unnecessary if the reactants are intimately mixed, e.g. by use of Raschig rings. In examples : (i) zinc chloride solution, paraformaldehyde, propylene and methylene chloride are reacted at 120‹ C. for 12 hrs. under pressure; the resulting butylene-glycol-formal is separated by fractional distillation; (ii) trimethyl-ethylene, aqueous formaldehyde and concentrated hydrochloric acid are refluxed for 10 mins. to produce the trimethyl-butyleneglycolformal (formula given); (iii) isopentylene-glycolformal is prepared by reacting isobutylene and formaldehyde or paraformaldehyde with either phosphotungstic acid and benzene solvent, phosphoric acid, concentrated hydrochloric acid, or concentrated sulphuric. acid. The Provisional Specification refers to derivatives of strong mineral acids generally which have an acid reaction, as the catalyst.

Filed: 1968-07-22
Abstract: 1,178,380. Reactors. WESTINGHOUSE ELECTRIC CORP. 22 July, 1968 [28 Sept., 1967], No. 34862/68. Heading G6C. In a nuclear reactor safety system, borated water is. injected into the pressure vessel if the primary .coolant system fractures. Water is also sprayed into the interior of the containment structure and water is supplied to the coolant system to make up for leakage losses. A fall in pressure in the pressure vessel, due to loss of coolant, causes an immediate opening of valves in the line correcting the pressure vessel to the borated water tank. Simultaneously, water is also pumped into the pressure vessel from the refuelling tank to compensate for the coolant loss.
Patent GB-438294-A (GB)
Title: Improvements relating to pile fabrics
IPC: D03D27/00
Filed: 1934-12-05
Abstract: In pile fabrics such as velvets, plushes, corduroys, velveteens, transparent velvet, imitation fur, &c., the pile threads are coated with a wax-like substance obtainable by reaction between a higher fatty acid and a di- or poly-hydric alcohol or an alkylolamine or an aliphatic amine and which is readily emulsifiable in aqueous media, and are cut whilst thus coated, whereby pile of a uniform height is obtained, and setting of the pile by brushing and steaming, and subsequent securing is facilitated.  The scouring may be arranged to remove only part of the wax-like substance.  The pile may be set in various positions. The coating may be applied whilst molten by means of a roller, or in a solution or aqueous emulsion by a wick, roller or disc, &c., or by forcing the solution through a bobbin or cheese of the yarn, or by hank dipping.  Solid coatings are formed by cooling or evaporation of the solvent.  Examples of hydrocarbons, alcohols, esters, ethers, &c. which may be used as solvents &c. are described.  The pile yarns which may be of extra warp or weft may consist of organic esters or ethers of cellulose and may comprise a bundle of filaments free of twist, or with a twist up to 20 or 150 turns per inch.  The coating may comprise stearates and palmitates of glycol, or glycerol, each of these esters containing a free hydroxyl group, or stearates of monodi- or tri-ethanolamine, or the fatty acid salts of ethylene diamine and mono- or diamylamine or mixtures thereof.  It may also contain a substance which alone is not readily emulsifiable, but which in a mixture emulsifies in hot aqueous media, for example, palmitic and stearic acids and stearin, beeswax, carnauba wax, ozokerite, ceresin wax, and chlorinated naphthalene waxes.  Fatty acid compounds of tertiary amines may also be used, also cresylic acid, butyl acetate polymerized fatty acids and glycero or glycoboric acid or cetyl alcohol, or esters or ethers of higher fatty alcohols.  Plasticizing and softening agents such as glycols and glycerol and their esters and ethers, &c., sulphonated naphthalene and/or lubricants such as oleic acid, cotton seed and olive oil, &c. may be used, and may be applied to the yarn separately from the wax-like substances &c.

Filed: 1934-08-16
Abstract: 443,194. Electric welding. SCIAKY, D., 13<bis>, Rue Charles Fourier, Paris. Aug. 16, 1934, No. 35140/35. Convention date, Aug. 16, 1933. Divided out of 445,689, [Group XXXVII]. [Class 83 (iv)] In an A.C. welding system in which the circuit of a welding transformer is closed for a definite period, the power consumption during this period is measured by two wattmeter relays operating signals and alarms to show whether the power consumed is normal or is above or below that required for satisfactory welding, while, in the event of the weld being too weak or burnt, the associated relays act to prevent repetition of the welding operation until an independent hand switch is operated. Current is supplied to the welding electrodes 105 from mains A, B through a transformer 2, and the power consumption during the welding period is measured by wattmeters G, G<1> having current windings 21, 21<1> and voltage windings 20, 201. Correct current consumption is indicated by lamp 18<1>, undercurrent consumption by lamp 18 and alarm 17 and overcurrent consumption by lamp 18<11> and alarm 17<11>. Rectifier 101 supplies D.C. for operating certain of the relays. Cams 4, 4<1>, 4<11> driven from the synchronous motor 100 operate contacts 7, 71, 7<11> which cooperate respectively with a movable contact 13 and fixed contacts 13<1>, 13<11>. When the pedal P is depressed thus opening contact 34 and closing contact 10, the cams 4, 41, 4<11> initiate the operation of a series of relays which results in the opening of the valve R and the supply of welding current through transformer 2 for a definite period. The pressure fluid supplied through valve R operates a rocking member 12 which is coupled to all the movable contacts of relays F, J. If the current consumption is correct, as indicated by the lighting of lamp 13<1>, the welding operation can be repeated by depressing pedal P, but otherwise one of the lamps 18, 18<11> is lit and switch 27 is opened. The welding operation cannot be repeated until switch 27 is closed by hand.
