Title: Improvements relating to the control and operation of wing flaps of aircraft
IPC: B64C13/00
Filed: 1938-05-03
Abstract: 516,720. Fluid-pressure servomotor-control systems. PHILLIPS & POWIS AIRCRAFT, Ltd., and MILES, F. G. May 3, 1938, No. 13169. [Class 135] [Also in Group XXXIII] Aircraft flap-control means includes a doubleacting servo-control system having pilot-operable controlling means combined with means whereby operation of an engine-speed control operates the servo-control system. As shown, wing flaps 3 and a flap 4 disposed beneath the fuselage are operated, on rotation of a torque tube 5, by a servo-motor 12 through, respectively, links 7 and toggle levers 8 and a link 9. The servo-motor is actuated from a chamber 19 connected to the aero-engine induction-pipe 22 through a non- return valve 21, a moving-seat follow-up valve 15 being disposed between the chamber and the servo-motor. The valve 15 includes a part 31 having two ports and rotatable on movement of a control 17; a second part of the valve includes a member having three ports whereby one side of the servo-motor is connected through the part 31 to the chamber 19 and the other side of the servo-motor is connected to the atmosphere. The second part of the valve is connected through an arm 34 and a link 26 to the flap 4 whereby a follow-up action is obtained and the flaps are moved through an angle proportional to the displacement of the control 17. Further, the arrangement permits the flaps to move under the effect of, e.g., wind gusts. Specification 502,336, [Group XXXIII], is referred to.

Title: Improvements in the finishing of synthetic fibres
Inventor: SCHOFIELD ARTHUR
IPC: D06M15/263
Filed: 1954-05-06
Abstract: Artificial hydrophobic textile materials, in the form of yarns, knitted or woven fabric or loose fibre, are treated with a solution containing (1) a polymer of an unsaturated monobasic acid, or a copolymer, containing unreacted carboxyl groups, of one or more unsaturated mono- or dibasic acids and a compound of the formula CH2=CRR1, where R and R1 are hydrogen, aryl, alkyl, alkaryl, alkoxy, acyloxy, carboxy or alkoxy-carbonyl groups or halogen atoms, and (2) one or more polymeric polyhydric alcohols having not less than three ether groups per molecule; the impregnated materials are then dried and heated to bring about a reaction between the polymer or copolymer and the polyhydric alcohol.  Unreacted carboxyl groups are left in the resulting crosslinked, insoluble polymer.  The materials treated may be composed of polyamides, polyurethanes, polyesters, polyethylene, polyvinyl chloride, copolymers of vinyl chloride and vinyl acetate, acrylonitrile, polvinylidene chloride, cellulose acetate, cellulose aceto-propionate, benzyl cellulose or glass. The unsaturated acid for selfpolymerization may be acrylic or methacrylic acid.  The acid for copolymerization with another monomer may be acrylic, methacrylic, crotonic, maleic, fumaric, citraconic or mesaconic.  Anhydrides of the acids may be used. The monomer for copolymerization with the acid may be acrylic acid, methacrylic acid, styrene, a substituted styrene, a vinyl ester, an acrylic or methacrylic acid ester, a vinyl alkyl ether; vinyl chloride or vinylidene chloride.  In the examples, copolymers of acrylic acid and vinyl acetate; styrene and maleic anhydride; vinyl acetate and maleic anhydride; ethyl-vinyl ether and maleic anhydride; styrene, vinyl acetate and maleic anhydride; vinyl acetate, crotonic acid and maleic anhydride; vinyl acetate and mesaconic acid and n-butyl vinyl ether and maleic anhydride are mentioned.  The polyhydric alcohol may be a polyethylene glycol or polyglycerol, which may be used alone or in association with sorbitol, mannitol or pentaerythritol.  After impregnation the material may be mangled and dried, e.g. in hot air, and baked at about 120 DEG  to 150 DEG C.  The impregnation may be effected by padding, spraying or immersion and the impregnant, which may be an aqueous alkaline or alcoholic solution, may contain zinc chloride, phosphoric acid or p-toluene sulphonic acid as a catalyst. After heating the material may be washed in water or soap. Specification 647,273 is referred to.

Title: Substituted beta-naphthols and compositions containing the same
Filed: 1958-04-29
Abstract: The invention comprises (cyclohexanone-21)-yl-1-beta-naphthol, and the preparation thereof by heating beta-naphthol with a 2-halogeno-cyclohexanone in the presence of an acid acceptor, and preferably in the presence of an inert organic diluent, advantageously one that is an entraining agent for water.  The inert organic diluent may be an ether (e.g. anisol or dioxan) or a cyclic hydrocarbon (e.g. toluene, xylene or tetrahydronaphthalene) or a mixture of these substances.  The product may be characterized by conversion into its benzoic ester or methyl ether, the latter yielding a 2 : 4-dinitrophenylhydrazone and also being capable of being reduced to the corresponding alcohol, the phenylurethane of which is described.ALSO:Pharmaceutical compositions comprise (cyclohexanone - 21) - yl - 1 - beta - naphthol in admixture with a pharmacologically acceptable diluent.  The compositions may take the form of tablets, aqueous or aqueous-alcoholic suspensions to be taken by the mouth, or suppositories.  The tablets may contain binders, substances which facilitate the disintegration thereof and inert materials.  Aqueous and aqueous-alcoholic suspensions may include surface-active materials such as emulsifying agents. Suppositories may include natural or synthetic excipients of the usual kinds.  The compositions are used for the relief of coughs, and may be used together with other pharmaceutical materials currently in use which have a soothing action on coughs, e.g. codeine, ethyl morphine, narcoteine, papaverine, terpene, potassium quaiacol sulphate, sodium benzoate, sodium citrate, ammonium chloride, lobelia and ipecacuanha and antihistamines.

Patent GB-889015-A (GB)
Title: Improvements in or relating to machines for selectively playing gramophone records
IPC: G07F17/30
Filed: 1957-05-18
Abstract: 889,015. Automatic gramophones. BOURN, L. E. A. Aug. 18, 1958 [May 18, 1957], No. 13875/57. Class 40 (2). Apparatus for selectively playing a plurality of gramophone records comprises a telephone dialling device employing multi-line selectors adapted to move to a selected position, and means whereby in response to the insertion of a coin, a circuit corresponding to the selected position is established to cause a corresponding record to be played. The record playing apparatus comprises a rotatable mandrel 3 carrying spaced records 1, each of which is associated with an individual pick-up and arm 5 which may be pulled down into contact with the record by an individual solenoid 23. When the selector dial 7, Fig. 7, is operated, the forward rotation closes contact 8 and completes a circuit through a winding wl (if the selector has been left on any of the contacts 1 to 10 inclusive, which is normally the case). The winding w opens contacts wlc, which then successively close and open until the moving contacts cm and c<SP>1</SP>m of line selector SA are set to c0 and c<SP>1</SP>0 respectively. The return motion of dial 7 causes winding w2 to become energized and similarly ratchets the contacts cm and c<SP>1</SP>m to selected contact positions, say 10. Insertion of a coin temporarily closes a circuit through a winding 10w which is locked on by contact 10wc, and a contact 10wcl is moved upwardly to complete a circuit through a winding w3 which closes contacts w3cl and w3c2 to energize the amplifier and motor. A circuit through the unselected contacts c<SP>11</SP>0 to c<SP>11</SP>9; inclusive, of line selector SB closes a circuit through winding w4 to ratchet selector SB to position 10 which open circuits winding w4 and leaves the selector in position 10 in which a circuit is completed through a winding 10wl which causes current to pass through the solenoid 23 associated with pick-up above the tenth record 1 on shaft 3 whereby the pick-up is drawn downward and starts to reproduce. At the end of the record a limit switch 26 is closed which releases the hold-on circuit of winding 10w, whereby the pick-up is lifted and returned under a slight gravitational bias to its initial position, and contact 10wcl is released to cause selector SB to be ratcheted round to the next dead contact, which is normally c<SP>11</SP>0, i.e. when no further records have been selected, and the system is now ready for another selection. If another number has already been dialled, the contacts of selector SA will already be at their correct setting and contact 10wcl is maintained in the upper position so that a further operation will proceed. Any number of pre-selections will automatically be carried out.
