Title: Improvements relating to aircraft control linkages
IPC: B64C27/54
Filed: 1960-02-18
Abstract: 898,174. Controlling aircraft; aircraft seats. UNITED AIRCRAFT CORPORATION. Feb. 18, 1960 [Feb. 19, 1959], No. 5778/60. Class 4. An aircraft has a seat rotatably mounted over an opening in a floor, an operator's control stick mounted for movement with the seat and for pivotal movement relative to the seat and carrying a separately movable member, two control means requiring actuation, and means passing through the opening and connecting one control means to the stick and the other to the movable member to transmit control movements in any position of the seat. A helicopter seat 60, Fig. 1, is pivotally mounted about a horizontal axis in a U-shaped member 64 having an opening 62. To member 64 is fixed an annular box section member 70 having a cylindrical downward extension passing through an opening in the floor 76, Fig. 2, and terminating in a flange 72. The floor is reinforced by a welded and riveted annular box section member 79, having bearing surfaces 80, 84, whereby the seat with members 64 and 70 can rotate about a vertical axis. An annular disc 86 attached to flange 72 prevents the seat from lifting off the floor. A collective pitch lever 48, Fig. 1, with a throttle twist grip 100 is attached to a shaft 154 supported in member 64 by bearings 88, 90. A yoke with tines 8, 11 is rotatably mounted in an arm 4 fast to shaft 154. The yoke and a bell crank 160 connected to the rotor blade pitch change mechanism are interconnected by a link 158 composed of two relatively rotatable parts 30, 32 part 30 having arms 44, 46, pivoted to the tines 8, 11, and part 32 having arms 50, 52 connected by a bridge 54 pivoted to bell crank 160. Rotation of the seat merely causes relative rotation of parts 30, 32, and does not affect collective pitch control. The throttle twist grip 100 is secured to a shaft 102 having a gear 112 engaging a toothed segment 108 on a shaft 106 mounted in a housing 104 on shaft 154. An arm 110 on shaft 106 is pivoted to a rod 114 within shaft 154 and pivoted to one end of a centrally pivoted lever 116. Rod 114 contains a device 115 permitting relative rotation of the ends of rod 114, so that collective pitch charge does not apply torque to rod 114. The other end of lever 116 is connected by rod 130 to bell crank 120 the free end of which is connected by link 136, located between arms 44, 46 and arms 50, 52 to a bell crank 134 connected to the engine fuel control. Link 136 contains a device 142, permitting relative rotation of the ends of the link, so that rotation of the seat does not affect throttle control. The longitudinal axes of links 158, 136 coincide with the axis of rotation of the seat. Specifications 698,712, 789,979 and 862,001 are referred to.

Title: Improvements in or relating to reverse socket pivot joint assemblies

IPC: F16C11/06
Filed: 1967-02-07
Abstract: 1,106,947. Ball joints; resilient hearing members. TRW Inc. 7 Feb., 1967, No. 5903/ 67. Heading B2F. [Also in Division F2] A ball joint assembly of the reverse socket type (i.e. wherein the socket housing is open at one end only and the bearing member and ball head are inserted through this end, the margin thereof subsequently being turned in to retain them) has a resilient, anti-friction material bearing member press-fitted into the socket, and compressed by the turning-in of the socket margin to pre-load the joint; all the machining and assembling operations can thus be performed from one side. A socket member housing 11, with a socket 13 having a frusto-conical surface with two degrees of taper 16 and 17, has a closed end 15 and an open end 14. A ball stud 12 comprising a ball end 20, with a shank 21 having a threaded end 22, and preferably having a recess 26 with a opening 27 axially opposite the shank, for holding lubricant, fits with clearance into the socket. A resilient bearing member 30, of polyolefin material, has an outer frusto-conical surface conforming with the inside of the socket, a segmental spherical inner surface and a terminal aperture 35. On assembly, the ball is inserted into the bearing member, by elastically deforming the neck of the latter, and the ball and hearing member are then force-fitted into the socket, a degree of compression of the member being effected. A ring 40 is then passed over the ball shank to abut against the end face 41 of the bearing member, and the upper marginal edge 14 of the housing turned in to form an annular shoulder 44; this exerts a loading force on the ring 40 and hence on the bearing member, to complete the compression of the latter and preload the joint A boot seal 60 may be present, to retain lubricant and prevent ingress of dirt; the seal may be of rubber or other elastomer; and may be external and sealed to the socket and ball shank by circular spring clips, as in Fig. 1, or internal of the housing, having its neck bonded to the ring 40 or to a ring plug overlying said ring. Alternatively, the seal may be a rubber annulus, the lower side of which is bonded to the ring 40 and also engaged under the turned-in annular shoulder and the upper side being compressed, to sealingly engage with the ball shank, by the lower face of an eye member 25 (Fig. 1), secured by a nut on the threaded end of the shank- (see Division F2).

Abstract: 198,425. Preston, L. G., Horton, C. E., and Harris, G. W. March 1, 1922. Aerials; directive signalling. - In a radiogoniometer for direction-finding, the cross-coils are so spaced as to give a large field of substantially evenly-distributed flux, whilst the dimensions of the search coil are such that it rotates wholly within this field. The coils are preferably square in section. The two divisions of each of the field coils 3, 4 are separated by a distance equal to half the side of the square, and the notches carrying the outside coil 4 are cut somewhat deeper than those carrying the inside coil 3 so that both coils have precisely equal areas. The size of the search coil 6 must not exceed seventenths that of the field coils, and its length is kept sufficiently small to enable it to pass between the separated divisions of the outer coils, to facilitate assembly or repair. The field coils may he made rotatable and the search coil fixed. The angle-dividing device and true bearing indicators described in Specification 189,516 may be fitted to the aerial.

An extensible conveyer comprises a fixed frame A supporting a frame B movable relative thereto and which in turn supports a frame C movable relative thereto at a relative speed equal to that between the frames A, B. An endless conveyer belt D extends around pairs of rollers 21, 6, 43, 44, 71 and 65 carried by the respective frames A, B, C. The means for moving the frame B, C comprises an electric motor 48 mounted on the frame B and driving sprockets 34 engaging chains 14 fixed to the frame A, and driving sprockets 39, 40 through further sprockets 36, 37 and a chain 38, which sprockets 39, 40 engage chains 67 fixed to the frame C. All the sprockets 34, 36, 37, 39, 40 are of the same diameter thus resulting in equal relative speeds between the respective frames. The frames move relative to each other on rollers 18, 30, 51 co-operating respectively with angle section side beams 10, 12, 53. The conveyer D is driven by an electric motor 70 rotating about a fixed shaft 61 within the roller 71 at the front of the frame C and the required belt tension is obtained by the roller 21 mounted by springs 22 on a bar 7 adjustable in relation to the frame A. The roller 6 in the diagonally opposite corner of the frame A to the roller 21 forms one end of the conveying surface 78 of the conveyer and the roller 71 forms the other. The extension of the conveyer surface 78 takes place with a corresponding reduction in the lengths 76, 77 between rollers 65, 43 and between rollers 44, 21 respectively. Further extension is possible as the lengths 76, 77 approach the vertical by rotation of the roller 21 about the adjustable bar 7. The conveyer D is supported along its upper run 78 by decking 4, 73 extending between the respective side members 2, 53 of the frames A, C. The frame A may have retractable wheels whereby the conveyer is portable. The conveyer is applicable for mounting on a loading bay (P) Fig.- 5, not shown, for loading and unloading lorries (G) by extension and retraction across the carrying portion thereof.
