Title: Improvements in change speed gearing suitable for propelling aircraft
IPC: F16H61/02
Filed: 1929-06-13
Abstract: 329,199. Barbarou, M. J.-B. March 12, 1929, [Convention date]. Variable-speed gearing specially suitable for propelling aircraft comprises an epicyclic train which yields a solid drive and reduced speed, and in which the changing is cushioned by engagement of friction surfaces. Driving and driven shafts 1, 4 carry respectively an internallytoothed ring 2 and the carrier 5 of planets 42 meshing therewith. Sun gear 7 is loose on driven shaft 4, and upon its extended boss 8 slides a disc 10 which is moved to change speed. In position shown, the toothed periphery 15 of a disc 10 is locked to the fixed casing at 16 so that the gearing works to effect reduced speed. To change up, pressure oil admitted at 24 passes through duct 23 and presses pistons 21 to the right. Disc 10 is carried along and strikes ball-ended spring plungers 28 which bring a cone 30 on carrier 5 into engagement with a cone 3 on ring 2. This speeds up carrier 5 so that engagement of teeth 15 and 2 for the solid drive is facilitated. To change back, oil pressure is released, and springs 25 return disc 10. Before the teeth 15 engage teeth 16, a cone 14 on disc 10 engages a spring- pressed brake cone 32, by which the toothed engagement is cushioned. Exhaust gas may replace the oil.

Filed: 1955-06-24
Abstract: 769,891. Testing aerials and radio equipment. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1955 [June 29, 1954], No. 18345/55. Class 40(7) It is convenient, when testing all the radio equipment, for example, on an aircraft, to have all the transmitting test equipment mounted on a trolly 5 which may be placed some 20 or 30 feet in front of the craft out of the way of other operations being carried out on the craft. The test equipment may be arranged to provide automatically and in a given sequence all the test radiations required so that only one operator is required. In order to make use of such test equipment it is necessary that signals therefrom be received with adequate strength by the aerials associated with all the various equipment. However adequate signals are not normally received by directive and suppressed type aerials such, for example, as the downwardly directed mortar beacon receiver aerial 4. To overcome this difficulty receiving and re-radiating means 6 are provided, according to the invention, to produce a relatively strong local field at the suppressed aerial. The means 6 may comprise a quarter-wave line tuned by telescopic end sections 8. It may be mounted on an adjustable pedestal or suspended by suction caps from the underside of the craft.

Filed: 1954-06-23
Abstract: 763,956. Hydraulic jack locking means. BOEING AIRPLANE CO. June 23, 1954 [May 6, 1954], No. 18427/54. Class 69 (2). [Also in Group XXIV] Means for locking an hydraulic jack at each end of its stroke comprises a locking device mounted adjacent one face of the jack piston and duplicated at the other face, each locking device including a locking dog means reciprocated radially in the piston by an actuator and a toggle link, the locking dog means having a bevelled surface engageable with a complemental bevelled surface in the wall of the jack cylinder. A hydraulic jack for an aircraft landing unit comprises a cylinder 1 and a piston 2. A locking device is mounted adjacent each end of the piston and comprises ring segments 41 sliding within a groove 26 in the piston and moved outwardly by expanders 4 which are actuated, through toggle links 5, by a plunger 3. To lock the piston in the position shown liquid admitted through a port 11 to move the piston to the right passes through a port 28 to a chamber 27 where it acts on a face of the plunger 3 of smaller area than the opposite face which is in communication with the right-hand end of the cylinder. Plunger 3 is thus urged to the right and when the piston reaches the end of its stroke the segments 41 are moved outwards to bring a bevelled surface 40 into engagement with a bevelled shoulder 15 of the cylinder 1. In this locked position the toggle links 5 are aligned with the expanders 4. The parts are retained in locked position by a spring 31 which acts on the plunger 3. On applying pressure to a port 13 and opening port 11 to exhaust to expand the jack, chamber 27 is opened to exhaust and the pressure acting on the right-hand side of the right-hand plunger 3 urges it to the left against the pressure of the spring 31, breaking the toggle and allowing the segments 41 to be pushed inwardly by the co-operating bevels. The locking device for the other end works in a similar manner. Specification 763,955 is referred to.
