Title: A new and improved method of and improvements in or connected with the design and construction of folding wings or planes for aircraft
IPC: B64C3/56
Filed: 1936-10-09
Abstract: 486,758. Aircraft with folding wings. HUDSON, R. J. H. Oct. 9, 1936, No. 27388. [Class 4] In a folding-wing aircraft in which wing folding is required to take place by rotation about two mutually inclined axes, a wing is connected to the remaining structure by means comprising an element rotatably connected to the structure about a first axis and to the wing about a second axis intersecting the first axis substantially at a right-angle and an external strut or equivalent support pivoted to the aircraft about a third axis and pivoted to the wing about a fourth axis, the four axes intersecting in a point, and the third axis lying in a plane to which the first axis is substantially perpendicular. As applied to the folding of the wings of a high wing monoplane, Fig. 1, a centresection frame 3, which may comprise a tank, or a cabin roof, is hinged on axis A to fuselage 1 and wings 2 are hinged to frame 3 on axes B normal to axis A. Constraining struts 4 are hinged to fuselage 1 on axis C and to wing on axis D, axes C, D being at an angle to one another and all four axes being concurrent at F. Folding takes place initially by a rotation of the wing principally about axis D with raising of frame 3 and latterly by rotation principally about axis C. Axis A may be disposed further aft than shown to bring the wings lower when folded. By placing axis A well to the rear and high in relation to the wing and by modifying the positions of axes C, D the wing may be arranged to fold with the leading edge uppermost. Fig. 2 shows a similar arrangement applied to a biplane, in which an upper wing 22 is pivoted to a centre section 23 and the constrainer comprises a strut 24 and in which a lower wing 22A is attached to fuselage 21 by hinged connection on an axis B<1> to a bracket 23A rotatable about axis A<1>. Constraining members 24A are pivoted to fuselage and wing about axes C, D<1> of which the former is collinear with that of the corresponding upper wing constrainer 24 and the latter parallel to axis D of that constrainer. Since the lower wing thus moves through a geometrically similar path to that of the upper wing the two wings may be interconnected by parallel motion struts 25. The wings may be held extended by connection of centre section 23 to a fitting 26. The pivots may have some slight universal freedom to prevent straining.

Title: Means for controlling the temperature of hot gases
Inventor: JOSEPHIFIELD RICHARD
IPC: G05D23/185
Filed: 1947-10-16
Abstract: 644,140. Gas turbine plant. LUCAS, Ltd., J. Oct. 16. 1947, No. 27711. [Class 110(iii)] [Also in Group XXIX] Apparatus for controlling the temperature of hot gases in the combustion chambers of internal combustion turbines and jet-propulsion prime movers comprises a pair of orifices a, b of fixed area with a gas cooling means f, g between them and means dependent on the pressures at the entrances of the orifices for controlling a fluid-operated servo mechanism which operates a temperature regulating means. The apparatus depends for its operation on the formula T 1 =KT 2 P 1 <SP>2</SP>/P 2 <SP>2</SP> where T, T 2  and P 1  P 2  are the absolute temperatures and pressures respectively at the entrances to the orifices and K is a constant. T 2  is maintained constant by mixing valve h influenced by a bi-metallic strip i. The orifices are joined by parallel passages e, f one of which is cooled, for example, by fins g. T, the temperature of the hot gases entering the pipe c is thus measured by the ratio P 1 <SP>2</SP>/P 2 <SP>2</SP>. A chamber k adjacent the orifice a contains a lever m with an adjustable fulcrum n. The lever is loaded by opposite pairs of capsules o, q and r, s of which the capsules q, r are evacuated. The capsule o is subject to the pressure P, at the entrance to the orifice a. The capsule s is subject to the pressure at the exit of the orifice a which in this case is substantially the same as the pressure P 2  at the entrance to the orifice b. If this is not the case, the passage t is connected to the entrance of the orifice b. The lever m operates a leak-off valve u controlling a spring-loaded servopiston 3 connected directly to a pressure fluid supply 7 on one side and through a restricted byepass 6 in the piston or the wall of its cylinder on the other side. The piston rod 5 may control the output of a variable delivery fuel pump supplying fuel to the combustion chamber, or it may control a byepass device or a throttle valve in the fuel supply line. The temperature may also be controlled by regulating the inflow of air to the hot gases.

Filed: 1958-08-29
Abstract: 863,132. Temperature alarms. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. Aug. 24, 1959 [Aug. 29, 1958], No. 27750/58. Class 118. [Also in Group XL (c)] Refers to apparatus comprising a temperature responsive device whose resistance varies with temperature, indicating or control means, and a transistor switch which operates when the temperature responsive device reaches a predetermined temperature to operate the indicating or control means. The output from a transistor oscillator Tr1 is fed from transfer T1 to transformer T2 via the temperature responsive element 10, When the output from T2 reaches a predetermined level, it triggers a monostable circuit Tr2, Tr3 (see Group XL (c)) which produces output pulse having a mark/ space ratio such that transistor Tr4 is held conducting, energizing indication lamp 13, or a control relay (not shown). The temperature responsive element itself comprises a length of coaxial cable, the resistance between the inner and outer of which decreases as the temperature increases. Operation of test button 12 energizes relay coil 11d and connects the inner conductor of the cable in series with the coupling between T1 and T2. The output from T2 is therefore sufficient to operate the indicator or control device. Failure to operate when button 12 is pressed indicates a discontinuity in the inner conductor 10a.

Abstract: 403,787. Pressure-reducing valves. ELECTRO-MECHANICAL BRAKE CO., Ltd., and SMITH, S., Eagle Works, West Bromwich. .Oct. 7, 1932, No. 27921. [Class 135.] The main valve e of a pressure-reducing device having an inlet b and outlet c is connected to a piston or diaphragm k influenced above by the pressure in a chamber l and below by outlet pressure, being balanced by a piston g to the lower side of which pressure passes by way of a passage h opened when the main valve is opened. The chamber l is connected to the inlet through a valve m spring-pressed at n and operated by a piston or diaphragm s subject below to the pressure in the chamber l and above to spring pressure adjustable by a hand-screw v. With both valves m, e open, pressure increases in chamber l until valve m closes owing to diaphragm s overcoming spring t, the normal condition. Should outlet pressure exceed the pressure in chamber l, valve e is closed by diaphragm k, the quantity of air expelled from chamber raising diaphragm s and escaping through a hollow valve r thereby raised from a seat q on the stem of valve m.
