Patent GB-732746-A (GB)
Title: Process for recovering cryolite from aluminium furnace waste and the like
IPC: C01F7/54
Filed: 1953-10-26
Abstract: In a process for recovering cryolite from materials containing aluminium and fluorine compounds, e.g. from waste material in electrolytic furnaces, the material is lixiviated with soda lye and the dissolved compounds containing fluorine and aluminium are precipitated with hydrofluoric acid.  The material, which has been previously stored in a damp atmosphere to hydrate the alumina it contains is warmed with soda lye and most of the aluminium and fluorine removed.  The remaining material can be treated with hydrofluoric acid, which is then added to the soda lye to produce cryolite.  Proportions of sodium and total fluorine contents are adjusted as necessary for cryolite formation.  If the original materials are poor in aluminium this is increased by adding alumina or aluminium fluoride.

Abstract: 925,471. Automatic control of aircraft. W. W. TRIGGS (Bell Aircraft Corporation). Aug. 31, 1959, No. 29603/59. Class 38 (4). [Also in Group XXIX] A power control system for an aircraft having a movable aerodynamic control surface, comprises a fluid-pressure actuator 16, 18 connected to the surface, a differentiallyfulcrumed manual control means 20, 50, 51 operatively connected with a resilientlycentred spool valve 48 in a housing 45 to move the spool in opposite directions from neutral position to control the actuator 16, 18 when the fulcrumed manual control means is unrestrained, a differential pressure - control valve or flapper 64 responsive to automatic signals and arranged to apply differential fluid pressures to opposite ends of the spool valve 48, and an electromagnetically actuated selector valve 65 for selectively switching the output of the control valve 64 to the spool valve 48 and selectively switching a secondary fluid pressure supply to cause actuation or deactuation of a pressure-responsive device such as a pair of lock-out pistons 58, 59 which are adapted to restrain or restore normal fulcruming movements of the manual control means 20, 50, 51. As shown, the output of the flapper control valve 64 may also be applied to opposite ends of the pressure-responsive device 58, 59, so that the arrangement is operable in three modes, namely (a) manual or " power control," (b) automatic or " autopilot " control, and (c) a stability augmentation mode in which both the manual and automatic controls are effective simultaneously. On actuation of the lock-out pistons 58, 59, the fulcrumed levers 50, 51 engage abutments 62, 63 on the housing 45 to restrain their normal fulcruming movement. The flapper valve 64 may be responsive to electrical signals. A cross-connection valve 74 across the power actuator allows for emergency operation in the event of loss of hydraulic pressure. In an alternative embodiment, duplicate spool valves operating the actuator in a dual supply system are engaged by tappets yoked together by side yokes connected to a pair of lockout or decoupler pistons, one of these yokes being coupled to the fulcrumed manual input member 20. A solenoid valve in a supply line to the differential pressure control valve and to the space between the pistons provides for engagement or disengagement of the tappets with the valve spools to allow operation in the manual or autopilot modes. To provide for operation in the third mode, the pistons are mounted in a sliding spring-urged over-ride cylinder whereby the tappets can be brought manually into over-riding engagement with the spool valves, only one position of this solenoid valve being necessary to cover both the autopilot and stability augmentation modes. An overall system shown diagrammatically in Fig. 1 may be responsive to signals of the nature indicated and may include the devices named in this Figure.
Patent GB-666239-A (GB)
Title: Soluble cutting oils
Filed: 1948-11-16
Abstract: The tendency of transparent soluble cutting oils to foam is inhibited by adding to the cutting oil both a small amount of a silicone polymer of the order of 0.01 to 0.1 per cent based on the whole composition and 0.005 to 0.2 per cent of a dispersing agent for the silicone polymer, the dispersing agent being an aliphatic or cyclic amine or an alkyl phenol or mixtures thereof.  Amines mentioned are ethanolamine, di-ethanolamine, triethanolamine, monoheptyl diphenylamine, di-heptyl diphenylamine, diphenylamine, triphenylamine, cyclohexylamine and dicyclohexylamine while alkyl phenols mentioned are diamylphenol and tertiary butyl phenol.  A mutual solvent for the silicone polymer and the oil may also be added, and this mutual solvent may be a glycol ether, particularly a glycol mono-alkyl ether.  Thus glycol mono-ethyl ether or glycol mono-butyl ether, in conjunction, if desired with an alcohol such as ethyl alcohol may be employed as mutual solvent.  Where the transparent soluble cutting oil is prepared by adding sodium hydroxide to an oil containing metal salts of petroleum sulphonic acids and rosin, the foam-inhibiting composition may be added during the saponification without causing settling or precipitation o fhte rosin soap.  The preferred inhibited transparent soluble cutting oil comprises 20-70 per cent mineral oil by weight, 10-50 per cent oil-soluble metal salts of petroleum sulphonic acids, 0-15 per cent of soap (preferably rosin soap), 1-5 per cent of a glycol ether, 0.01-0.1 per cent of silicone polymer, and 0.005-0.2 per cent of the dispersing agent.  In an example an inhibited transparent soluble cutting oil is prepared by mixing mineral oil, sodium or calcium mahogany sulphonates, rosin, sodium hydroxide, water, glycol monobutyl ether, the silicone polymer known commercially as "Antifoam A," and either triethanolamine or dicyclohexylamine. For comparison purposes, an un-inhibited transparent soluble cutting oil is described which is prepared by mixing mineral oil, sodium or calcium mahogany sulphonates, rosin, sodium hydroxide, water and ethyl alcohol.  Specifications 591,767 and 600,693 and U.S.A. Specification 2,375,007 are referred to.

Abstract: 866,059. Agglutinated fibrous materials. FREUDENBERG KOMMANDITGESELLSCHAFT AUF AKTIEN, CARL. Sept. 24, 1957 [Sept. 25, 1956], No. 30021/57. Class 140. A self-supporting filter mat consisting of cardable textile fibres connected by means of a bonding agent is produced by impregnating a web of textile fibres in a prestabilized condition, with a homogeneous solution, free from wetting- agents, of a film-forming bonding agent, or a precursor of such an agent, in an organic solvent, excess impregnant being squeezed off till a content is reached substantially corresponding to the weight of the dry fibrous web, and the impregnated mat being then subjected to heat without pressure. As textile fibres there may be used cotton, ramie, bast, wool, regenerated cellulose, cellulose acetate, polyamide, polyvinyl or polyvinylidene chloride, polyacrylonitrile, polyvinyl alcohol, polyethylene, and polyesters. A minor amount of water may be added to the organic solvent solution. Prior to impregnation, one or both surfaces of the fleece may be pre-stabilized by applying thereto by spraying or brushing a small amount of the same or a different bonding agent and causing it to set, or the fleece may be pre-stabilized throughout its whole thickness by shrinkage of polyvinyl chloride fibres incorporated in the fleece, or by fusion of polythene powder added during the carding. As shown, a fleece 1, having both its surfaces 2, 2 pre-stabilized, is conducted through an impregnating bath 7 and then through the nip of rolls 3, 3. The compressed fleece, upon emerging from the nip at 8 expands and is led to a drying chamber (not shown). Examples describe the production of filter mats by impregnating webs consisting of polyamide and wool fibres stabilized by coating with a foamed aqueous dispersion of a copolymer of vinyl chloride and vinyl acetate with bonding agents consisting of alcohol-soluble polyamide dissolved in a mixture of methyl alcohol, benzene and water; and hexa-methylolmelamine and diammonium phosphate dissolved in a mixture of methyl alcohol and water; further examples describe the impregnation of a web of polyester and polyvinyl chloride fibres that has been pre-stabilized by heating to shrink the polyvinyl chloride fibres, with a composition made by mixing a methylene chloride solution of triphenylmethane tri-isocyanate- 4,4<SP>1</SP>,4<SP>11</SP> and a trichloroethylene solution of a polyester, and the impregnation with the above solution of alcohol-soluble polyamide of a web of viscose rayon fibres bonded by fusion of polythene powder incorporated during carding.

Filed: 1972-06-29
Abstract: 1392054 Electrophonic musical instruments PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 June 1972 [2 July 1971] 30426/72 Heading G5J Apparatus for converting a tone of frequency f into a lower tone of frequency xf comprises cascaded divide-by-two frequency dividers each corresponding to the digits of x in binary notation, all dividers corresponding to adjacent similar digits being connected to a NAND or NOR circuit together with the output of the NAND or NOR connected to the next adjacent lower group of dividers corresponding to adjacent similar digits. The ratios of the converters may be chosen to give mean-tone, equal temperament, or just intonation, or any other desired, such as 31-note equal temperament. For 12-note equal temperament three versions of a converter are described (Fig. 5, not shown) giving different degrees of accuracy. Fig. 3 shows a typical converter, which reduces the frequency by a factor 0À934593, or 0À111011110100001 in binary notation, this being one of the two intervals in the mean-tone intonation. The converter comprises a chain of divide-by-two dividers d 1 -d 18 . Each divider feeds the next and also, where required, feeds one of a set of NAND or NOR gates G 1 -G 7 . The dividers are notionally arranged in one-to-one correspondence with the bits of the conversion ratio, as shown. Each group of one or more dividers corresponding to identical successive bits feeds one gate (e.g. in the example shown dividers d 5 -d 8  feed gate G 4 ). Where the binary fraction ends in ... 01 the output of the divider corresponding to the last unit is fed to the same gate as the output of the previous divider, as shown. The later dividers d 8 -d 18  provide audio tones, and subsonic frequencies for tremolo circuits or the like. Two integrated circuit versions of a converter are described (Figs. 7 and 8, not shown). In an alternative type of converter (Fig. 6, not shown) the outputs of each group of divider are fed to an auxiliary gate. The output of this gate is inverted and fed to the main set of gates.

Abstract: 901,394. Making helically seamed tubing. KUCKENS, A. Dec. 23, 1958 [Oct. 10, 1958], No. 30521/60. Divided out of 901,391. Class 83 (4). A method of producing tubes with a helically disposed welding seam in which strip, guided at its edges, is fed by a roll assembly into a coiling shaper box or die positioned obliquely to the path of the strip is characterized in that the reactions of the forces appearing as a result of stresses or constraints in the strip and/or the positioning of the strip are utilized for adjusting the operation of the feeder roll assembly for compensating inaccuracies in the travel of the strip. Strip 201 from a coil 202 is fed through straightening rolls 231 by driven feed rolls 204, 205, urged together by an hydraulic ram 206, through guides 219, 220 and between lateral guides 221, to rollers 223, 224, 225, the latter two driven by means 228, in a sleeve-like shaper tool 222 where the strip is coiled into a tube 236. The edges of the strip are engaged by guides 234, 235 on which are provided pressure measurement heads so that, if the strip presses too hard against one or other guide, a frame 203 for the feed rolls 204, 205 is caused to pivot slightly about a vertical axis by gear means 229, 208 to relieve the pressure. The same effect can be obtained by moving one feed roll bearing 237, Fig. 4, laterally by hydraulic cylinder means 238, or 239, controlled by the pressure measurement heads or one of the rams 206 at the ends of the feed rolls may be pressed down more heavily than the other. The straightening roll system 231 is movable laterally on rollers 232, 233. Specification 901,392 also is referred to
