Title: Improvements in or relating to air brakes for aircraft
IPC: B64C9/32
Filed: 1942-07-03
Abstract: 562,371. Coutrolling aircraft. FAIREY AVIATION CO., Ltd., and YOUNGMAN, R. T. July 3, 1942, No. 9220. [Class 4] An aircraft having an air brake of the kind described in Specification 562,365, wherein a flap is adapted to be projected into or withdrawn from the airstream by a bellows device in communication with the throat of a venturi-tube fitted with a butterfly valve, has a pipe g from a venturi-tube f connected to the front end of a second venturi-tube, the throat of which is connected by a pipe to a bellows device for actuating a flap a, while another passage n leads from the rear end of the second venturitube to a bellows device for actuating a second flap c opposite to the first flap. A butterfly valve 12 in the venturi-tube f enables the bellows devices to be put under pressure or suction at will. The two flaps a, c may, as shown, be mounted above and below the trailing portion of a wing and the lower flap c may be on an auxiliary surface d normally nested within a recess beneath the wing and adapted to' be lowered as described in Specifications 461,157, 467,465 or 493,391. A soft rubber ring m normally seals the joint between the passage n and the second venturi-tube and when the surface d is lowered the joint is broken and the two flaps a, c are withdrawn to inoperative position. Alternatively, the passage n may have a flexible connection to the second venturitube so that both flaps a, c may be kept projected if required. To prevent unequal movement of the flaps they are connected by cables p, q, Fig. 5, to two spring-urged slides r, s of insulating material carrying contacts v, w. Should the movements be unequal, the circuit of a solenoid x is closed to cause its armature y to open the butterfly valve 12 and retract both flaps, for which purpose the armature is linked to the control lever 11 which actuates the valve 12. Alternatively, the slides r, s may actuate hydraulic or pneumatic valves controlling a jack device for moving the lever 11. The cable q in the case of a flap on the movable surface d, is led alongside one of the links by which the surface is raised and lowered.

Title: Improvements in warp tying-in machines
IPC: D03J1/14
Filed: 1922-04-03
Abstract: 201,598. Eanes, H. P. April 3, 1922. Warp threads, uniting.-Two sheets of warps to be tied together are passed respectively over and under rubber fillets 26 and secured to tension rollers 27, 28. The carriage 1 carrying the tying- mechanism is intermittingly advanced a distance corresponding to the warp thickness by means of a lead screw 5 which is grooved longitudinally and engaged by a pawl 15 operated by a lever 16 and an adjustable cam 20 which is reciprocated by an eccentric 62 on the main shaft 63. When the selector S is advanced by the eccentric 61, a tongue 44, Figs. 17 and 18, passes between the sheets of warps which enter the groove between the fingers 34 and push back a double-ended pivoted trip 50 and thus lower a trigger 53 into the path of a cam 56 on a slide 55. When the slide 55 is advanced by the eccentric 62, its front pivoted part is lifted by the trigger 53 and it, in conjunction with a spring 45, rotates a disc 38 having a bill 39, Fig. 19, which separates one upper and one lower warp which are cut by the knife 73 on the return of the selector. The separated warps have meanwhile .been brought under a catch 81, Fig. 8, on the shuttle 80 which is rotated by a rack 88 and eccentric on the main shaft 63 to wind the two warps round the base of the tapered part 97, Fig. 14, of a slotted post 84, Figs. 14 and 15, the warps being crossed by a depressor 98 operated by a cam 99 moving with the rack bar 88 and the crossed warps drawn through the loop by a latch 106, Figs. 13, 14, and 15, on the stripper-arm 102 which is operated bv a second cam 109, Fig. 1, moving with the rack bar 88. When the arm 102 is lifted, a pin 112 on the post 84 engages the tail 111 of the latch which is thereby tilted and grips the warps between the rounded edges 115, 116 of the latch and arm, but cuts the treads between the knifeedges 113, 114 of the latch and post 84. During the tightening of the knot the warps are tensioned in the slot 117, Fig. 8, of the shuttle.

Abstract: 1,081,172. Fluid-pressure servomotor systems. MAGNETROL Inc. March 5, 1965, No. 9551/65. Heading G3P. Variations in liquid level in a container 10 are sensed by a float 11 connected to a magnetic armature 15 which co-operates with a magnet 17 carried on a pivoted lever 18 to cause rotation of a cam 25 to thereby displace a flapper 27 relative to a nozzle 26 supplied with air from a conduit 31 via a restriction 32. Consequent pressure changes in conduit 30 actuate a diaphragm 34 connected to a valve member 40 to cause corresponding pressure changes in a conduit 37 which communicates with a control device for correction of the liquid level. The conduit 37 also communicates with bellows 38, 41, the latter via an adjustable restriction 39, mounted on a lever 42 pivoted at 43 and having an extension 50 which provides a pivot for a lever 45 engaging the upper ends of the bellows. A spring 48, the rate of which is adjustable, also engages lever 45 which abuts a pin 47 carried by a beam 28 pivoted at 29 and carrying both the flapper and the nozzle. The arrangement is such that a movement of the flapper first causes bellows 38 to rotate lever 45 and beam 28 to thereby cause the nozzle to move relative to the flapper, and then, as the bellows 41 responds, the lever 45 is moved in the opposite direction to return the nozzle towards the steady state position, which position can be varied by means of screw 44. The operating range is varied by adjusting the stiffness of spring 48. The controller may also control fluid-flow or the like.

Title: Manufacture of cellulose derivatives and of artificial filaments, films and other shaped structures therefrom
IPC: C08B13/02
Filed: 1935-05-29
Abstract: Alkyl-, hydroxyalkyl, and hydroxy acidderivatives of cellulose which are insoluble in caustic alkali solutions and cannot be made soluble therein by cooling a mixture with caustic soda solution to a temperature between 5 and -25 DEG  C. and thereafter allowing the temperature to rise to between 0 DEG  C. and room temperature, and which are insoluble in water and the usual organic solvents, are treated with carbon disulphide in presence of caustic alkali.  The alkyl-, hydroxyalkyl-, and hydroxy acid-derivatives are prepared by using a proportion of etherifying agent which is insufficient to produce an alkali-soluble cellulose derivative, or by using a temperature too low, a reaction time too short, or a caustic alkali solution too dilute to produce an alkali-soluble derivative.  The structures formed from the cellulose derivative xanthate solutions, whether supportless as with filaments, threads, films, strips, and the like, or supported on rigid or pliable supports as with dressings, coatings, sizings, printings and the like, may be coagulated for example, in a bath capable of coagulating viscose. Simultaneously with or subsequently to coagulation, the structures may be plasticized, for example, by means of a bath containing between 25 and 70 per cent of sulphuric acid.  To the solution may be added other colloids such as cellulose xanthate, and also softening agents.  In an example, 1,000 parts of linters are steeped in caustic soda of 18 per cent strength, pressed to 3,000--5,000 parts and reacted with 30--50 parts of ethylene chlorhydrin, glycerol a -monochlorhydrin, or di-methyl or di-ethyl sulphate, 30--80 parts of monochloracetic acid, or 20--35 parts of ethylene oxide, for 3 hours at 18--21 DEG  C. Thereafter more caustic soda is added together with carbon disulphide, and the product of the reaction dissolved in water. The solution may be extruded as filaments or films, applied to a woven fabric with or without first mixing with a pigment, filler, softening agent or other colloid, employed for pasting together two or more sheets of paper or card boards or fabrics, or shaped to produce thick plates, and the solution thereupon coagulated, or coagulated and plasticized.  During the xanthation or before dissolution of the xanthate, the reaction mass may be cooled down, e.g. to 0 or -10 DEG  C.  Other examples are given using other proportions of etherifying agents, carbon disulphide, and caustic alkali, and other temperatures and reaction times.  There may be used also mixtures of the above-described etherifying agents. Specifications 25246/11, [Class 2 (iii)], 281,352, 312,197, 323,731, 323,732, 335,993, 335,994, [all in Class 2 (ii)], 341,899, 357,167, 357,527, 357,595, 390,517, 393,932, 408,950, and 457,031 are referred to.
