Title: An electro-mechanical operating system for the selector valve of a hydraulically operated arrester hook arm of an aircraft
Inventor: FOSTER ALFRED GEORGE
IPC: B64C25/68
Filed: 1950-11-10
Abstract: 672,653. Aircraft arrester gear. BLACKBURN & GENERAL AIRCRAFT, Ltd. Nov. 10, 1950, No. 27542/50. Class 4. In an aircraft provided with a hydraulically operated arrester hook arm, the selector valve which controls the supply of pressure liquid from a source of supply through an accumulator to an arm actuating jack is positioned adjacent the arm and is operated by a remotely controlled electric actuator so mounted that emergency manual control of the valve may be effected in the air or on the ground. The valve 1 is connected by a rod 7 to a two-part lever comprising arms 8 and 10 mounted on a common pivot 9 fast with the aircraft structure 24 and releasably connected by a spring loaded plunger 13. The movement of the lever 8 is limited by projections 8<SP>2</SP>, 8<SP>3</SP> which engage a stop 25 and the lever 10 is connected by a rod 11 to the movable element of an electric actuator 12, the body of which is pivotally anchored on a normally fixed lever 15, pivoted at 16 to the structure 24 and urged in an anti-clockwise direction by a compression spring 17. Movement of the lever 15 is prevented by a slot 21 therein engaging a roller 18 mounted on a spring urged lever 19 which carries a control cable 23. In normal actuation of the valve 1 by the actuator 12 the levers 8, 10, the rod 7 and the valve lever 6 are moved as a unit but should the source of electrical power fail manual actuation of the lever 19 by means of a pull on the cable 23 will release the lever 15 which will, be rotated anticlockwise by the spring 17 to move the actuator bodily to adjust the valve 1. The roller 18 will engage the slot 21 automatically when the valve is re-set by manual movement of the levers 8, 10. When the aircraft is on the ground the arrester arm jack may be supplied with pressure liquid from an accumulator. In this case the valve 1 is manually actuated by the lever 8 which is released from the lever 10 by movement of the handle 14.

The central coupling 8 which is displaceable on a track 14 comprises a body 21, Fig. 2, provided with a straight passage 22 for fluid and a double acting hydraulic device 29 which slides sealing sleeves 25, 26 over end portions 23, 24 and the ends of aligned tubes 6, 7. The head 4 is capable of displacement on the beam 13 but may be secured in position by a rack 15. After fluid testing has been carried out, the tubes are disengaged from the heads 2, 4, then lowered and discharged by the transporter 17. A faulty tube may be lowered and replaced by another tube, by operating only that part of the device 17 with which it is associated, the other tube being retained by rendering the corresponding electromagnetic coupling 19 inoperative.

[Also in Divisions G4 and H3] A flashing beacon operated from a low voltage source comprises a cold cathode electric discharge tube 3, a blocking oscillator 1 having parallel transistors T1A, T1B as its active elements and a transformer 2 to step up the voltage sufficiently to operate discharge tube 3. Transformer 2 has a primary winding P in the collector circuit of transistors T1A, T1B and a secondary winding S1 connected to the discharge tube 3. A further secondary winding S2 is connected in the base circuit of transistors T1A, T1B to provide feedback between the collectors and bases of the transistors. The blocking frequency of oscillator 1 is adjustable by altering the value of resistance RS in a resistance capacitance network R7, R8, C3 connected to the base circuit of the transistors T1A, T1B. To give a visually perceptible flashing light, operation of oscillator 1 is periodically interrupted by a multivibrator 4 or by a coding unit whioh gives a coded flash signal. Multivibrator 4 supplies modulated pulses through a buffer circuit comprising transistor T4 to a switching transistor T5 which switches off oscillator 1 during each positive pulse of the multivibrator.

Title: Improvements in or relating to wire coils
IPC: H01F41/06

Abstract: 675,272. Winding coils. LELAND, G. H. Oct. 28, 1948 [Nov. 12, 1947], No. 28004/48. Classes 120(ii) and 120(iii) [Also in Group XXXV] A method of winding a layer-wound magnet coil includes the steps of winding each full turn of wire in part-turn increments and shifting each part-turn axially of the coil with relation to the next preceding part-turn, wherein the shifts of each layer are in the same axial direction, and wherein each layer is wound in half-turn increments and each succeeding half-turn 20 is shifted at 21, lengthwise of the axis of the coil with relation to the next preceding half-turn in said layer, a distance slightly greater than one-half of the diameter of the wire. In a modification, the method comprises the steps of winding two parallel lengths of wire simultaneously in quarter-turn increments and shifting succeeding quarterturns of both wires axially of the coil with relation to the next preceding quarter-turns of the respective wires, the sum of the shifts in each turn of the two wires being slightly greater than the combined diameters of the wires. The former upon which the first coil is wound comprises pairs of segments 30, 31 provided with transverse grooves, those of one pair of segments being spaced axially from those of the other pair by a distance slightly exceeding one-half the diameter of the wire. Spring-pressed plungers 36 position the segments 30, 31 in the hub 27 driven by a shaft 28. The length of the coil is governed by the distance between the wall 25 of the hub and the wall 26 of a conical element 40 which may be removed to collapse the former for the removal of the coil. When the multi-layer coil is completed, it is tied at two oppositely disposed positions, and, for this purpose, the walls 25, 26 are slotted at 47, 48 (not shown). For winding the second coil, the former is provided with four segments E, F, G, H, Fig. 14, each provided with a wide groove 50 at one end, the groove 50 being at the wall 25 for segments E, G, and at the wall 26 for the segments F, H. approximately by one-half the diameter of approximately by one-half the diameetr of the wire. The two wires 1, 2 which are wound simultaneously are entered into the former at segments E, G respectively and are displaced in quarter-turn increments as they are wound upon the former to produce, when tied, the coil shown in Fig 14a.

Abstract: 1530054 Controlling and lubricating compressor pumps CHICAGO PNEUMATIC TOOL CO 5 July 1977 [3 Aug 1976] 28101/77 Heading F1N In an air compressor system comprising a rotary air compressor 10 and an oil sump at the bottom of a receiver 16, an intake valve 14 is arranged to be normally closed at start-up and is provided with a bleed hole so that at start-up a partial vacuum is developed in the compressor which assists the movement of oil from the sump to lubricate the compressor. The intake valve is gradually opened by pressure in the right hand side of cylinder 27 led via line 26 from the receiver. To moderate the air intake the left hand side of cylinder 27 is connected to the service line 25. Loop line 34 feeds the cylinder via a pressure regulator 37. A by-pass line 39 passes air directly to the cylinder when pressure reaches a predetermined maximum. This is accomplished by a differential pressure switch 42 which controls a 3-way solenoid valve 41. At low pressures ports 1 and 2 are connected so that the left hand side of the cylinder is vented to atmosphere. During normal working ports 1 and 3 are connected. When a maximum pressure is achieved ports 2 and 3 are connected and the intake valve is closed.
