Patent GB-660842-A (GB)
Title: Improvements in or relating to controls for aircraft
IPC: B64C13/42
Filed: 1949-02-19
Abstract: 660,842. Aircraft controls. BLACKBURN & GENERAL AIRCRAFT, Ltd., and HOLEY, N. Feb. 10, 1950 [Feb. 19,1949], No. 4557/49. Class 4. To impose control loading on power-operated aircraft controls under diving conditions the control member for initiating operation of the dive brakes is associated with the control member operating the flaps such that the bringing into operation and retraction of the dive brakes partly extends and retracts the flaps, while the flap control may be independently operated to extend or retract the flaps as required. As shown the dive brakes and flaps are operated hydraulically through selector valves 16, 1 respectively. The pilot's dive brake control member 14 is connected to the plunger 15 of the selector valve 16 through a push-pull cable 13 and links 17, 18, the members 13, 17 being connected to a lever 11 mounted on a shaft 7, while the flap control member 9 is connected to the plunger 5 of the selector valve through a cable 8 and a lever 6 also mounted on the shaft 7. In addition, the casing 1. of the flap selector valve is attached to a member 2 connected to the lever 11 by levers 3, 10 and a spring link 12. Operation of the control 14 causes movement of the plunger 15 of the brake selector valve, and at the same time moves the lever 11 into alignment with thelever 6, movement of the lever 11 being communicated to the casing 1 of the flap selector valve by the members 2, 3, 10, 12 to initiate movement of the flaps. The rotation of levers 3, 10 moves a roller 21 on an arm 20 into the path of a cam 22, which is caused to slide longitudinally by a link 24 connected to one of the flaps or to the arm of the flap-operating jack. The roller 21 rides over the inclined surface 22' of cam 22 partially to retract the valve casing 1 and thus cause a partial lowering only of the flaps. The movement of the lever 10 relative to the lever 11 is accommodated by extension of the spring link 12. Plunger 5 of the flap selector valve may be moved for independent operation of the flaps at any time by actuation of the control lever 9. The flaps are raised upon retraction of the dive brakes.

Abstract: 354,707. Annealing ; tinning. COLD METAL PROCESS CO., 1200, City Bank Building, Youngstown, Ohio, U.S.A.-(Assignees of Steckel, A. P. ; 1200, City Bank Building, Youngstown, Ohio, U.S.A.) Feb. 11, 1930, No. 4620. Convention date, Dec. 19, 1929. [Classes 72 and 82 (ii).] Strip metal after hot rolling and pickling is cold rolled as described in Specification 292,494, [Class 83 (iv), Metals, Working], by a pair of small rolls 7, the strip S being pulled through the rolls backward and forward by a pair of driven drums 14, 15 which wind and unwind the strip alternately, the edges of the strip being annealed in edge heaters 44, Fig. 14. The strip S is coupled at each end to the drums by leader strips 18, the junction 19 carrying a pin 35 which, when the strip nears the rolling limit in one direction, forces the switch lever 36 of the electric motor drive 22 to stop it. The rolls 7 are backed by top and bottom rolls 6 with screwdown 13 and by side rolls 11. Each drum 14, Fig. 6, has a ratchet toothed wheel coupled by a pawl 24 to gear wheels 21 driven from a common electric motor gear 22. The pawl 24 is disengaged, when the strip is to be pulled through backwards, by pushing in a hand knob 33, Fig. 6, which lifts spring-pressed pin 29 engaging arm 26 of pawl 24, Fig. 9. This rolling with free rollers and tension of the strip is said to give great reduction and polish without spreading of the edges of the strip. The strip is then passed through edge electric heaters 44, Figs. 14 and 15, supplied with hydrogen jets or other inert atmosphere, to anneal the edges. The strip then passes through a tinning bath 47 and is finally wound up on a reel 48. Fig. 16 shows a can made from part of a strip 51 being a crimped edge seam and 53 being the seams for receiving top and bottom covers to the can. Specifieation 5781/09, [Class 72, Iron &c.], is disclaimed.

Abstract: 1,087,201. Printing processes. RANK XEROX. Ltd Feb. 5, 1965 [Feb. 28, 1964], No. 5082/65. Heading B6C. [Also in Division G2] A powder image 19 which has been developedon, or transferred to, the surface of a coating 14 of micro-capsules supported on a plastic or  paper substrate 13 is fixed, by applying a uniform pressure to.rupture the capsules and release a fixing liquid. As shown, to obtain a pair of mutually reversed copies, instead of a single copy, a blank sheet 21 is placed with its face downwards over the powder image and pressure is applied to both sheets-by rollers 17 and 18. Examples are given of capsules containing a solvent for toner powders of gum copal sealing wax, coumarone indene, polystyrene, rosin modified phenol formaldehyde and copolymers of methacrylic esters and styrene. The solvent causes the major component of the powder to become tacky and adhere to the substrate. Alternatively, the capsules may contain an air hardenable liquid adhesive to secure insoluble toner particles of thermosetting resin or metal powders. As a further alternative, the capsules may contain thesolution of a leuco dye base in an oil such as olive oil, sperm oil, coconut oil or cottonseed oil. The dye is formed by reaction with acidified toner particles of silica gel, alumina, infusorial earth or acid clay. In a modification, the capsules contain a solution of an organometallic compound such as nickel acetylacetonate and the toner particles are of or include rubeanic acid. On rupturing the capsules, the rubeanic acid reacts to produce an intensely coloured nickel complex salt which is absorbed in the paper substrate allowing the remaining tonerparticles to be brushed off.
