Title: Improvements in or relating to helicopters and to rotating wing aircraft
IPC: B64C27/54
Filed: 1933-04-25
Abstract: 418,674. Aircraft with rotary wing systems. COATS, A. G., and RUTHERFORD, W. V. D'A., Gloucester House, Park Lane, London, and HAFNER, R., 47, Mantlergasse, Vienna. April 25, 1933, No. 11991. [Class 4.] In a helicopter or an auto-rotative wing aircraft, means controlled from the cockpit are provided for inclining a member about which the wing unit rotates in any direction relatively to the body unit and means are associated with the body and wing units for varying the incidence or pitch of the blades differentially according to the inclination of the wing unit to the body unit. In one form, the blades 1 of the wing unit are pivoted at 2 on their axes X, Y in the manner described in Specification 418,698 to a hub member 3 rotatably mounted on a shaft 9 connected by a universal balljoint 11, 12 to a member 14 capable of axial movement in a member 13 carried by the body of the machine. The blades 1 are provided with radius rods 16 extending inwardly of the pivot 2 and connected to a rotatable member 19 journalled on the member 13 by ball-joints 17 slidable on pivots 18. The shaft 9 may be controlled or extended downwardly to form the control stick and the member 19 may be driven. The hub member 3 and the member 19 may be interchanged. In a modification, in which the present invention is applied to aircraft of the kind set forth in Specification 418,212, the blades are connected to the member 3 by slidable ball joints and are braced against centrifugal force by triangular flexible bracing. A tractor airscrew driven from the engine for rotating the wing system or from an auxiliary engine may be provided. The Provisional Specification describes a method for applying the present invention to that set out in Specification 385,101.

Title: Improvements in electrical resistance devices for use in measuring the velocity of flow of fluids
IPC: G01P5/12
Filed: 1932-04-27
Abstract: 395,123. Wire resistances. POOLE, R., 193, Oswald Road, Chorlton-cum- Hardy, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. April 27. 1932, No. 12121. [Class 37.] A resistance for measuring the velocity of flow of a fluid by its cooling effect on a heated resistance comprises a grid of wire 4 associated with a series of stream-lined parallel barriers 1 arranged within a framework 2 so as to cause the fluid flo.wing past the wire to flow in a given direction. This arrangement ensures that any returning fluid doubling back upon its path has relatively little cooling effect on the wires. The apparatus shown is arranged for measuring the velocity of a current of air flowing vertically upwards. The bars 1 and the framework 2 are of moulded insulating material such as that known under the Registered Trade Mark " Bakelite " and are stream-lined in the vertical direction. Along the lower edges of the bars 1 is attached the resistance wire 4, which may be of pure nickel, the wire being passed through the end frame members 2a, 2b, as shown at 5. The free ends of the wire are passed through a hollow metal handle 3 provided with a thumb switch 6. Two stream-lined guide vanes 7 are arranged within the frame 2 below and at right-angles to the bars 1 in order to guide the air stream through the instrument.

Abstract: 842,551. Steering vehicles. SOC. D'ETUDES ET D'APPLICATIONS INDUSTRIELLES COMMERCIALES ET IMMOBILIERS INTER-TECHNIQUE. April 15, 1957 [April 19, 1956], No. 12190/57. Class 79(5). [Also in Group XXXII] A steering device comprises a rack and pinion mechanism 85, 87 in a housing 86 to which links 81 are attached by adjacent resilient joints 84. The rack is guided and any wear taken up by a guide 93 urged against the rack 85 by a spring 94. The links 81 are pivoted to arms 71 welded to the upper ends of tubes 12 of telescopic devices A. The stub axles of the steerable wheels R are rigid with the lower ends of the tubes 12 so that steering is effected by turning the tubes 12 about their axis XX. Each arm 71 has a split collar 72, Fig. 8, with a conical bore 73 which is eccentric to the bore in the arm. A spigot 74 of a ball 75 enclosed by a socket 77 attached to an arm 81 is held in the bore 73 by a nut 76. Turning of the spigot 74 in the bore 73 provides the adjustment for the relative position of the steering wheel 104 and the wheels R. The arrangement allows the steering mechanism to be placed above the clutch housing 6 at the rear of the motor M and reduces the length of the steering column 105.
