Title: Aerial barrage
IPC: F41H11/04
Filed: 1938-01-31
Abstract: 498,114. Aerial warfare. CAPRONI, G. Jan. 31, 1938, No. 3039. Convention date, Feb. 26, 1937. [Class 9 (ii)] An aerial barrage consists of a series of elements each comprising a balloon or balloons from which is suspended a contact bomb, said balloon or some of the balloons, exploding on reaching a certain predetermined height, known means being provided in the bomb for automatically exploding it at a predetermined altitude during its descent unless said bomb has previously exploded by contact with an aircraft. As shown, a bomb 1 is connected through a parachute 2 to a single balloon 3, which, on rising, gradually expands until it reaches the altitude at which the excess of the gas pressure inside it over the external air pressure causes it to explode. In descent, the parachute opens out causing the descent to take place at a comparatively slow velocity and the bomb, if it does not come into contact with an aircraft, explodes at a predetermined height from the ground. According to modifications, Figs. 2 and 3 (not shown), the parachute is dispensed with and the single balloon is replaced by several small balloons either grouped together or disposed in line vertically one above the other.

Title: Electrical transmission system

IPC: B64C13/24
Filed: 1965-01-25
Abstract: 1,081,792. Controlling V.T.O.L. aircraft. SPERRY GYROSCOPE CO. Ltd. Jan. 7, 1966 [Jan. 25, 1965], No. 3128/65. Heading B7G. [Also in Division G3] The pitch-angle of a hovering aircraft may be stabilized partially by movement of stick 9 to swivel flaps 8 at puffer nozzles 4, 5, but, if a disturbance is not counteracted completely a signal is produced at terminal 20A which is connected through R.C.-networks with rate gyro unit 16A and stick pick-off 17A. This signal passes to amplifier 15A so that motor 14A adjusts actuator A which is duplicated by actuator B controlled in the same manner. The amplifiers 15A, 15B, receive feedback signals from potentiometers associated with the actuators, the potentiometers 25A, 25B being crosscoupled and potentiometers 28A, 28B, being straight-coupled. Unequal resistors are placed in feedback leads 21A, 22A, to prevent reaching equilibrium with the actuators in dissimilar altitudes. If the actuator A is jammed at maximum extension, a large negative feedback signal is fed to amplifier 15A through lead 22A, but the motor 14A is not moved. A corresponding signal is supplied to amplifier 15B over lead 21B so that actuator B contracts. The length of the transmission link 10 is very nearly what it would be if both actuators were working properly. A fault-indicating device 30 responds to the voltages at points 27A, 27B, which normally should be equal. If automatic operation is to continue after the actuator A has jammed as described, lead 21B is earthed through capacitor 29, and potentiometer 28B must now develop twice its previous potential to counteract signals from the rate gyro unit and stick pick-off. If wiper 27A is open-circuited, it is driven with the wiper 25A to the negative end of its potentioneter. Actuator B is driven in the opposite direction, channel B operating at an increased gain. When positive power is removed accidentally from potentiometers 28A, 25A, the system operates normally while the wipers lie on the negative portions. When the wipers move on to the positive portions, motor 14A is driven to an end position, and motor 14B is driven to compensate. If wiper 24A is opencircuited, the gain of actuators A and B are respectively decreased and increased. In the event of amplifier 15A not responding to an input signal, leaving actuator A offset from null, then actuator B is driven to a nearly equal and opposite offset. The outputs from the rate gyro and pilot's stick pick-off are cross-coupled between the two channels to ensure that the control signals applied to the channels are substantially identical. Puffer nozzles, similar to nozzles 4, 5, are provided at the wing tips, all nozzles being fed from jet-lift engines 2, 3 and all are swivelable to provide yaw control.
