Title: Improvements in or relating to controlling means for high speed aircraft
IPC: B64C13/00
Filed: 1946-05-14
Abstract: 609,013. Aircraft controls. FAIREY AVIATION CO., Ltd., CHAPLIN, H. E., and COSTIGAN, F. J. May 14, 1946, No. 14538. [Class 4] Controlling means for high - speed aircraft comprises a pair of wings 11, 12, hingedly mounted about a transverse axis X-X, passing approximately through the centre of pressure of each wing, and operating means for each wing, to move it about its hinge to vary its incidence, interconnected with a pilot's control 20. Forwardlyplaced pins 17 project inwardly from each wing into inclined slots in members 19, which are each longitudinally traversed under the pilot's control to vary the incidence of the wings by raising or lowering the pins 17. Power is applied to members 19 through a T-shaped lever 36 connected through hydraulic servo means 38, 40, 41, as described in Specification 607,321, [Group XXIX], which produce a sense of " feel " at the pilot's control 20 which is connected to lever 36 by two separate linkages, respectively, including T- shaped levers 21, 22. Lever 36 has its crossmember mounted on a pivot 37, about which it can be turned for differential action on members 19; the pivot 37 is mounted in guides to allow the lever 36 to be moved forwardly or rearwardly for exerting like actions on the two members 19. The lever 21, which is actuated by transverse movements of control lever 20, turns on pivot 25, extending into a slot in the cross-member of the lever 21, and through linkage 32... 35 turns lever 36 about its pivot 37 for differential action on the wings. At the other end of the cross-member of lever 21 from linkage member 32 is pivoted a link 44 connected to ailerons for low-speed control. In the position of pivot 25 the highspeed and low-speed controls are both exerted by turning lever 21; as the speed increases, pressure from a pitot-tube 26e moves pivot 25 towards link 44 so that finally only the highspeed control is exerted. T-shaped lever 22 for exerting like actions on the wings, turns on movable pivot 26 to produce longitudinal movement of lever 36 through linkage 45, 46, 47 connected to pivot 37; lever 48 connected to lever 22 is used to actuate the elevators for low-speed control as well as the wings 11, 12 in the shown position of the pivot 26, which is adjusted similarly to pivot 25 by a pitot-tube 26e.

Title: Method of producing thoriated metallic tungsten bodies
IPC: H01J9/04
Filed: 1957-05-09
Abstract: A method of producing thoriated tungsten bodies (e.g. cathode filaments or heat resisting springs) from tungsten powder containing ThO2 by pressing, sintering and swaging, and contacting the pressed bodies with carbon at elevated temperatures, comprises introducing the carbon into the said tungsten body by contacting its surface, after the body has been sintered, with carbon at between 1300 DEG and 1700 DEG C.  The amount of ThO2 is from 0.2 to 4.0 per cent by weight, e.g. 2 per cent; the carbon contact occurs preferably both before and in the course of swaging and is effected by placing the body in a graphite tube or by passing a carbon-containing gas over the body in a ceramic or graphite tube.  A suitable gas is a mixture of hydrogen and sulphur-free illuminating gas the latter in amount 1 to 10 per cent by volume of the hydrogen; other hydrocarbons such as methane, propane, butane, or natural gas may also be in the mixture. Annealing after swaging is effected by heating to above 2000 DEG C. (e.g. 2500 DEG C) in hydrogen.  The appearance of Th globules on the surface during such annealing is said to be indicative of suitable carbon absorption.

Patent GB-612055-A (GB)
Title: Improvements in the treatment of fabrics containing thermoplastic cellulose derivative filaments or fibres
IPC: D06M11/82
Filed: 1946-05-16
Abstract: The safe-ironing temperature of a textile fabric comprising filaments or fibres having a basis of a thermoplastic organic derivative of cellulose is raised by wetting it with a solution, preferably an aqueous solution, of boric acid, evaporating the solvent so as to leave boric acid on the fabric, and subjecting the fabric to a heat treatment.  The boric acid solution may be applied by padding.  It may be of 1 to 15 per cent strength and it may be applied so that there remains on the fabric 75-125 per cent of solution based on the weight of the fabric.  The solution may be applied at raised temperature if desired.  The impregnated fabric may be dried in hot air at 85 DEG -110 DEG  C.  The subsequent heat treatment may be a hot mangling, calendering, or decatizing treatment.  The fabric may be decatized by winding it together with a heavy cotton blanket on to a perforated metal drum so that a layer of blanket alternates with each layer of fabric, and then passing steam under pressure through the fabric for a few minutes till the temperature of the fabric reaches 95 DEG -110 DEG  C.  In examples, cellulose acetate fabrics of taffeta weave and tricot fabrics are treated with boric acid solutions and then dried and calendered or decatized at 90 DEG -130 DEG  C.  The safe ironing temperature may be raised to above 280 DEG C.  The treated fabrics may be dry cleaned without losing this resistance to hot ironing, but if they are washed with water the boric acid may be removed and the resistance to hot ironing may be lost.  Garments may be subjected to the treatment so as to give them resistance to glazing when they are hot pressed.  The handle and draping properties of the fabrics are also improved by the treatment.
