Title: Improvements in or relating to power operated flying controls for aircraft
Inventor: NORTH JOHN DUDLEY
IPC: B64C13/24
Filed: 1953-11-06
Abstract: 777,046. Controlling aircraft. BOULTON PAUL AIRCRAFT, Ltd. Nov. 5, 1954 [Nov. 6, 1953], No. 30752/53. Class 4. A power operated aircraft flying control incorporates means for adding to each signal fed to the servomechanism a supplementary signal of short duration which is a function of the control column displacement and which initially displaces the control surface further than its final steady position. The signals are applied to the servo 4 of a control surface 7, rotating the aircraft about an axis associated with a high moment of inertia. A floating lever has one end A attached to a spring 1, and the other end B to a dashpot 2. It is connected at C to the servo input 5 and at D to a link 6 pivoted to the control column 3. On moving the control column, spring 1 is initially compressed, the lever pivoting on pivot B and the movement of rod 5 is greater than that of link 6. In the final steady state, the spring 1 has decompressed, shifting the piston of dashpot 2, thus the lever has pivoted on pivot A, and the movement of rod 5 is finally less than that of link 6. Inertia elements may be added to the transmission.

Abstract: 215,315. General Rubber Co., (Assignees of Coffin, J. G.). April 30, 1923, [Convention date]. Addition to 190,099. Spray evaporators.-In apparatus for drying comminuted rubber &c. latex, as described in the parent Specification, the deposit is collected on a surface movable through the chamber, means are provided for removing the spraying unit, and the operators are protected from the heating medium. A drying chamber 1, Fig. 2, of rectangular section at the bottom and approximating to a circular form at the top carries a housing 7 on the top, in which are located a latex tank, a furnace 14, and .means for manipulating the sprayer 11 which projects through an opening 10 in a depression 9 in the top of the chamber 1, and may be enclosed in a casing 37. The furnace 14 draws air from the outer air through an inlet 23, or from within the housing through an inlet 24, both inlets being controlled by a valve 25. The products of combustion pass by a pipe 27 to a manifold 28, and thence by pipes 29 with flared mouths to the drying chamber 1. The drying medium passes down the chamber 1 and is exhausted through openings 63, Fig. 3, extending across two sides of the chamber. A tortuous outlet is provided by plates 78 hinged at 79, plates 74 hinged at 75, a depending flap 77, and fixed plates 85, the final outlet to the atmosphere being at 87. The dried latex collects on a surface 64 consisting of detachable sections 65 capable of being moved through the chamber. The sections 65 are provided with flexible baffles 65<1> for preventing the escape of heating medium beneath the collecting surface. In operation, when sufficient dried latex has collected, the hinged plates are raised into the position shown in dotted lines, the rear portion of the plate 78 bears on the solid latex, and the heating medium is deflected up the flue 86 to the outlet 87. Clips 66 are now released, and the end section 65 is removed, cleared, and the empty section is taken to the other side of the chamber, attached, and the surface is moved forward a stage. For removing the spray unit 11, a detent-held carriage 52, Fig. 5, with depending spring arms 60 carries a cable 50 leading to a winch 54. The spray unit is hoisted by this cable until the spring arms 60 engage slots 62, when the detent is released, and the winch 54 is operated to draw the carriage into the position shown in dotted lines. To prevent hot gases from entering the housing 7, a fan 38, Fig. 2, maintains an excess pressure inside the housing 7 or casing 37 when such is provided. The opening 10 may also be closed by plates 39 operated by bevel gearing and hand wheel 48. Ventilating shafts 35 enable the drying chamber to be cooled rapidly.
