Title: Control systems for manoeuvrable craft
Inventor: GLENNY ARTHUR PHILIP
IPC: B60V1/14
Filed: 1961-04-19
Abstract: 1,024,561. Air cushion vehicles. SPERRY GYROSCOPE CO. Ltd. April 19, 1962 [April 19, 1961], No. 14080/61. Heading B7K. [Also in Division G3] An air cushion vehicle has variable-pitch propellers rotating about horizontal axes in units mounted forward and aft that may be swivelled about vertical axes with simultaneous adjustment of pitch by common control means so that the propulsive force may be varied over a range from full forward to low reverse, equal pitch angles being imparted to the propellers in the upper part of the range and unequal angles being imparted in the lower part of the range. As described, electric signals from a magnetic compass may control the swivelling of one or both propeller units by hydraulic actuators to maintain a desired heading automatically (see Division G3). Signals produced by movements of a water vane trailed by the vehicle may be introduced to counter drift. Both propeller units are swivelled when heading error exceeds a predetermined value and the positions of the two units are arranged to differ so that torque as well as side thrust is introduced. Drift correction is eliminated under these conditions. The propeller units may alternatively be swivelled by follow-up servo systems under the control of a hand wheel to steer the craft manually. Large movements of the hand wheel also control further follow-up servo systems to produce projection of side keels beneath the hull to assist steering. On changeover between manual and automatic control the controller not in use is returned to a central position by a cam. For speed control, the pitches of the two propellers may be adjusted through servosystems by common control means which ensure equal pitch angles in the upper part of the range and unequal pitch angles in the lower part of the range. The keels, which may be inclined, operated hydraulically, and rotated into position during projection from the hull, may be controlled so that the force on them corresponds to the signals controlling them. Interlocks may be provided to prevent projection of the keels at minimum throttle, propeller pitch, or speed.

Abstract: 311,941. Edwards, H. M. May 17, 1928. Flying toys and projectors therefor.-A toy parachute of the kind adapted to be thrown into the air in closed condition and to open at the apex of its flight, is held folded during the ascent by a resilient band b<2> carried by a member b. The band tends to straighten out but is prevented from so doing by a hook c pivoted at b<3> to the member b and engaging a loop b<2> on the free end of the band. During ascent the hook is held in the position shown in Fig. 1, by the effect of air friction on a streamer d that is attached to the hook and passes through a loop b<4> on the member b. At the apex of the flight the drag on the streamer ceases and the band is released, thus allowing the parachute to open. The parachute may be projected by whirling it round a stick passing through a loop in the end of the streamer d. Alternatively, the stick may be formed with a slot i<1>, Fig. 6, within which the loop d<4> may be held by a catch k that releases the loop upon pressure being removed from a finger lever m. The parachute is formed of a single flat piece of material and is treated at the edges with flexible cement to prevent fraying. In a modification, the resilient band b<1> is replaced by a pair of rigid jaws, one of which is formed integral with the member b. The second jaw is hinged to the outer end of the first and is held in closed position against the action of a spring by the hook c.
