Title: Improvements in or relating to aircraft with rotative wings
IPC: B64C27/02
Filed: 1925-11-19
Abstract: 263,988. La Cierva, J. de. Nov. 19, 1925. Machines supported by rotary wing systems; steering, balancing, and regulating altitude.-In an aircraft of the kind described in Specification 196,594 having a freely rotative hinged-wing system, means are provided for applying a torque, independent of that due to the action of the air, to the wing system, when its angular velocity tends to fall below the region of its optimum or other predetermined value. As shown in Fig. 3, the shaft F of the prime mover D drives an electric generator S supplying current through the leads T to an electric motor U, the armature of which is carried by the shaft C of the rotating wing-system B. A centrifugal governor V is provided on the shaft C to close the circuit to the motor U when the speed of the wing system falls below the predetermined value. In a modification employing mechanical transmission, the prime mover D drives the shaft C through a cone clutch G, G', Fig. 2, normally held disengaged by springs O, friction plates J. J<1> held in engagement by a spring N, a free wheel device M. M<1>, and bevel reducing gear-wheels L<1>, R. The ratio of the reduction gearing is such that over the normal range of prime mover speeds, and so long as the shaft C is rotating in the region of its optimum value, the free-wheel device permits the wing-system to over-run free from the prime mover, but when the velocity of the wing-system falls, the free wheel device engages and transmits a small torque to the system. The friction plates J, J<1> introduce the necessary slip to ensure that the take-up of torque, is gradual, but where sufficient slip exists in the clutch G, G<1>, the plates J, J<1> may be dispensed with. A lever P operated. from the pilot's seat is provided for engaging the clutch when required. Alternatively the clutch may be normally engaged and manual means provided for disengaging it. The couple tending to rotate the body of the aircraft when the torque is applied may be neutralized by longitudinal fins or vanes.

An axial ray is one which is deflected by the prism system to emerge parallel to its direction of incidence. Each compound prism may deviate the F-ray more than the C-ray or vice versa. The invention may be combined with that of Specification 745,315. Fig. 2 shows an arrangement in which the front prism consists of two prism elements and the rear prism of three prism elements the path of an axial ray passing through the system from rear to front being illustrated. The rear compound prism may also consist of two prism elements the two inner prism elements of the compound prisms pointing to the same or to opposite sides of the system.

Abstract: 163,735. Sproule, A. H., and McKenzie, J. H. Nov. 29, 1919. Valves; regulating.-In an engine constructed as shown in Fig. 1, each impulse acts simultaneously upon two pistons 4, 5 connected to separate crank shafts geared together so that the shaft 7 makes two revolutions during each rotation of the shaft 8. To vary the volume of the clearance space to meet different conditions of running, the pistons may be adjusted relatively by altering the angular positions of the crank shafts, which are connected through helical or other gearing to a transverse shaft (not shown). Rotary valves 11, which may be connected to, and adjusted simultaneously with, the mechanism for altering the relative positions of the pistons, control the admission and delivery of charges to and from the crank chambers 9, 10. These valves have divisions 23 which are inclined in the direction of their length.

Rows of pistoncontrolled terminal exhaust ports open into a passage 31 containing an adjustable cylindrical valve 32 adapted to cut out the ports 29, 30 as desired. To start the engine in an opposite direction to that of normal running, the crank of the piston 4 is set behind the other crank.

As shown, each head 31, Fig. 3, is provided with adjustable brackets 32 carrying the rollers 34 and with two hollow branches 40, Fig. 6, provided with nozzles 42 which, preferably, are adjustable to vary the direction of the jets. The hose 44 is supported, as the head travels along the track, by wheeled carriages 60 formed with clamps 54 to grip the hose. Stops 46, 50 are hinged at the end of the track to allow the nozzle head to enter from either end. In use, a stop, e.g. 50, is turned down and a head 31 is slipped on the track. When the water is turned on, the reaction of the jets on the floor drives the head across the floor. It may be moved back by a pull on the hose or on a cable attached to the head. In a modification, Fig. 8, a header 82 carrying the nozzles 86 is swivelled to the nozzle head 80, and can be rotated by cables 98, 100, so that the direction of travel of the head can be reversed by reversing the header.

In an automatic control system a dynamoelectric machine supplying a load circuit is controlled in accordance with voltage variations across the load circuit detected by a plurality of networks each of which contains capacity and saturable inductance means only and the impedance of which varies as a function of load circuit voltage. In Fig. 1, to maintain constant the terminal voltage of a D.C. generator 1 driven by a prime mover 2, a field winding 7 of an amplidyne exciter 6 is energized from a rectifier 9 supplied from an A.C. source in series with a saturable inductance 13 in parallel with a condenser 12, and an opposing exciter field winding 8 is energized from a rectifier 10 supplied from the same A.C. source in series with a saturable inductance 16 in parallel with a condenser 15, the two saturable inductances being controlled by D.C. windings 18, 19 energized in series from the generator terminals 3, 4. The capacities of condensers 12, 15 are chosen so that resonance with their associated saturable inductances occurs at different values of the terminal voltage above and below the desired value to give a sensitive control characteristic. Voltage level is adjustable by a rheostat 20. In a modification, Fig. 3 (not shown), there is no exciter and the opposed exciter field windings are replaced by opposed D.C. windings of a saturable inductance in parallel with a condenser, connected in series with the A.C. supply to a rectifier energizing the generator field directly. The invention may be applied to voltage control of alternators.
