Title: Improvements in or relating to gyroscopic systems for controlling dirigible objects such as aeroplanes
IPC: B64C1/00
Filed: 1925-07-18
Abstract: 365,186. Automatic steering of aircraft ; gyroscopic apparatus. MEREDITH, F. W., Royal Aircraft Establishment, South Farnborough, Hampshire. July 18, 1925, No. 18385. [Class 4.] In means for controlling a dirigible object such as an aeroplane a single gyroscope comprising a rotor possessing three axes of freedom and having the rotor axis in the fore-and-aft direction of the aeroplane is employed for controlling aerodynamically both the steering and pitching movements of the aeroplane. A gyro rotor 1, Fig. 1, is mounted with its axis 2-2 in the fore-and-aft direction of an aeroplane in an inner gimbal ring or pitch ring 4 which is in turn pivotally mounted on a horizontal axis 5-5, Fig. 2, at right-angles to 2-2 in an outer gimbal ring or azimuth ring 6 pivoted on a vertical axis 7-7 in a frame 8. Rotation of the azimuth ring 6 relative to frame 8 is caused to operate a piston valve 10, Fig. 2, controlling the supply of compressed air to a servomotor 17 of which the piston is coupled by cables 19, 20 to the rudder. The' piston-rod 18 of the servomotor is coupled by a link to the frame 8 which is pivotally mounted on the aeroplane whereby a follow-up effect is obtained. Movement of the pitch ring 4 similarly operates a piston valve 25 controlling a servomotor 32 of which the piston-rod 33 is connected to elevator cables 34, 35. A follow-up effect is obtained by slidably mounting the piston valve casing 29 in vertical guides 37 in frame 8 and connecting it to the piston-rod 33 by Bowden wire or similar mechanism 38, 39. The above system is stated to be particularly applicable to aircraft which may be flown without aileron control. Specifications 365,187, 365,188, [Group XX], and 365,190 are referred to.

Title: Improvements in and relating to the pyrolysis of hydrocarbons and apparatus therefor
IPC: C07C2/76
Filed: 1956-06-20
Abstract: <FORM:0822039/IV (a)/1> An apparatus for pyrolysing a fluid hydrocarbon stock, particularly for pyrolysing methane to give acetylene, comprises a combustion chamber communicating with mixing means for fuel and oxidant at one end and a constricted throat at the other, such throat connecting with a pyrolysis chamber which communicates at its other end with quenching means, and inlet means for the hydrocarbon stock comprising openings in the peripheral inner wall between the constricted throat and the pyrolysis chamber so that the hydrocarbon stock is injected directly into the flowing stream of combustion products.  Preferably the throat section is adapted to introduce the products from the combustion chamber into the process chamber at a velocity greater than March number 0.5. Injector member 22 comprises an oxidant conduit 70 communicating with ports 72 arranged vertical to and around the conical face at the lower end. This conical face forms with conical walls 24 an annular conical passage 26 through which flows the fuel introduced through conduit 74.  By suitably maintaining a pressure ratio across the ports 72 and the passage 26 of greater than 2 : 1 velocities at or near sonic are achieved.  The mixed gases pass into the combustion chamber 32 constructed of refractory material 110 lines with metal ceramic material 114.  After combustion the gases pass through the constricted throat section 34 also suitably composed of metal ceramic material into the process chamber 40 constructed of refractory material 112 and lined with a metal ceramic 116.  At the entrance to the chamber near the throat section is positioned the hydrocarbon inlet fed by the conduit 60. If the hydrocarbon is liquid it passes as a fine spray into the chamber 40 with the high-velocity combustion products which are preferably travelling at or near sonic speed.  The products are quenched, preferably within 4 milliseconds from the commencement of pyrolysis, by the introduction of a quenching fluid through the ports 50 fed by conduit 56.  Water cooling conduits 80 and 88, 90 and 98, and 100 and 108 are also provided.

[Class 80 (ii)] A change-speed gear suitable for driving the supercharging compressor of an internal-combustion engine comprises two step-up planetary trains of different ratios brought into action by arresting their annuli 8, 22, Fig. 1, respectively, by moving a double-acting disc brake 17 axially by fluid pressure according to the position of a valve 47 which is moved by hand, or, upon an aeroplane, by a manometer. Separate planet gears 4, 5 of the two gear trains are supported on the same carrier spider 2 fast on a driving- shaft 1. Two corresponding sun gears 15, 30 are fast on a driven shaft 16 and are driven at different relatively-high speeds when the annuli 8, 22 are held. The control ring 17 slides axially on pins 20 and is thrust positively in one and the other direction by two opposed rings of servomotor pistons 32, 33. Fluid under pressure enters by an aperture 44, Fig. 3, and, in the position of the valve 47 shown, passes by a port 42 and annular conduit 37 to behind the pistons 32, so that the annulus 22 is held. When the valve 47 is pulled right of Fig. 3, the fluid passes by a cross duct 48 to an annular conduit 40, Fig. 1, to behind the pistons 33, so that the annulus 8 is held.

Abstract: 1346964 Up-and-over door DEMAG AG 27 April 1972 [28 April 1971 27 Nov 1971] 19551/72 Heading E2M An up-and-over door 1 is operable automatically by a carriage 11 connected to the door by a linkage and adapted to be moved along a guideway 8 by a motor 4 acting through a flexible element 7 which incorporates a resilient member, such as a spring 12 which allows the element 7 to lengthen when the door is moved manually. This allows the element 7 to slip on drive pulley 5 when the motor is braked. The linkage may comprise arms 14, 15, Fig. 2, the arm 14 being spring- biased against a stop 21. As the motor is operated to move the carriage to the left, the arms become co-linear and at the same time cable 19 pulls bolt (20), Fig. 1 (not shown) from its socket; further movement of the carriage opens the door. Alternatively, Fig. 5, the linkage 15 may comprise inner and outer tubes 15a, 15b urged apart by a spring 31 which is of such strength that as the door is being closed it is not compressed until the door reaches its closed position, whereupon shortening of the linkage 15 allows bolt (20), Fig. 4, (not shown) to be pushed into its socket by spring (23).
