Patent GB-1482318-A (GB)
Title: Door mechanism
IPC: E05F15/04
Filed: 1975-07-14
Abstract: 1482318 Locking devices in swivel door drive mechanisms E BODE 14 July 1975 [15 July 1974] 29429/75 Heading E2M A drive mechanism 7 acting via a pivoting column 3 and arms 6 on a door 2 includes a drive shaft 3a to the upper end of which is secured an arm 11; a locking member 16 being movable into the path of the arm 11 to prevent movement of the drive mechanism out of a closed position. Member 16 is secured to a shaft 15 and is normally urged by a pressure fluid piston and cylinder means 12 (which acts on the shaft via an arm 14 arranged above the arm 16) to an inoperative position; failure of the pressure fluid causing a biassing spring (not shown) to move member 16 to the locking position shown. In the case of compressed air operated doors, the means 12 could be supplied with air from the door drive circuit and failure in this circuit would lock the doors closed. A manual cable pull 22 can be operated to effect unlocking. A lug 17 projects from the shaft 15 and cooperates with stops 18, 18a. Above the locking mechanism a stub axle is secured to shaft 3a which carries two cams actuating switches to indicate the door position. As shown in Fig. 1 preferably double doors are employed, each with a drive mechanism 7, 8.

Filed: 1962-08-02
Abstract: 969,787. Bearings; lubricating. ROLLS-ROYCE Ltd. Aug. 2, 1962, No. 29820/62. Heading F2A. Apparatus comprises a bearing carried by a fixed structure in which a shaft is rotatably mounted, an annular lubricating-oil reservoir mounted within the shaft and rotatable therewith, and means to feed oil from the reservoir to the bearing. In the form shown the apparatus comprises a casing 11 within which is mounted a bearing 24 wherein is rotatably mounted a shaft 23 in which is mounted an annular structure 52 as shown in Fig. 2, a bearing 60 being mounted within it supporting a shaft 41 therein, lubricating oil being fed from the structure 52 to the bearings 24 and 60. The structure 52 includes an oil reservoir 47 and an annular member 46 through which passes an oil conduit 61 to the reservoir 47, with which communicates an oil conduit 62 communicating with the bearing 60. The reservoir 47 has a drilling 48 so that oil may drip therefrom to the portion 28 of a sleeve 26, to flow over the portion 29 of a sleeve 27 to the drillings 30, 31 leading to the bearing 24. The shaft 41 is driven from the shaft 23 by way of sleeves 26, 35 and splines 32, 33, 38 and 40. Some oil from the bearing 60 is conveyed along the interior of the wall 51 of the reservoir 47, on one end of which it is received, to fall into the lipped flange 36 before passing through apertures 37 to lubricate the splines 32, 33. Oil passes therefrom into the lipped flange 71 and through apertures 72 in a wall 65 to spaced compartments of a member 63 carried by the shaft 23, the radially-inner end of which communicates through drillings 76 in a boss 73 with a sleeve 35 splined to the shaft 41 at 38, 40. In the form shown the casing 11 is that of a gasturbine engine 10, the compressor 13 and turbine 16 thereof being mounted on the shaft 23, adjacent the upstream end of which is the bearing 24, the shaft 41 driving the engine fuel pump 44.

Title: Improvements relating to the joining of plastic covered wires and the like
IPC: H01R4/12
Filed: 1960-08-30
Abstract: 901,777. Direct connections between conductors. SYMONS, N. S. Aug. 30, 1960 [Sept. 11, 1959; March 3, 1960], No. 29896/60. Class 38(1). A joint for thermoplastic coated wires is formed by bringing the coated wires into preliminary contact, applying heat to the parts in contact to soften the thermoplastic insulation, applying pressure to the joint while the plastic is soft, to cause the insulation to be forced out from between the wires and the wires to be brought into good electrical contact, and finally heating and moulding the insulation at the joint, if necessary, to make a seal against water. In the joint shown in Figs 1 to 4, the two loosely entwined insulated wires 1, 2, e.g. the two conductors of two telephone cables, are heated until the insulation (e.g. polyethylene) is soft, whence the two wires are further twisted together, forcing the two conductors together through the insulation. The coalesced thermoplastic is cut at point 6, forced back to point 9, where the entwined conductors are cut and then pushed back over the severed conductor ends and is finally heated to coalesce and form a water-tight seal 11. Alternatively the two wires may be twisted together with their ends in opposite directions (Figs. 8, 9, not shown), or (Figs. 5 to 7, not shown), the two wires may be joined in a reef-knot and the conductors brought into contact by tightening the knot. The conductors may be coated with a low temperature melting solder during manufacture, the polyethylene (if used) forming a flux for the solder or, the conductors may be soldered when the insulation is pulled back.

Title: Improvements in aircraft of the helicopter type
IPC: B64C27/10
Filed: 1933-10-18
Abstract: 432,245. Aircraft with rotary - wing systems. ASBOTH, O., 1, Gower Street, London. Oct. 18, 1933, No. 29898/34. Divided out of 432,124. [Class 4] In a rotating-wing aircraft, stabilizing surfaces which in their position of rest are substantially vertical are adapted to be inclined relative to the air stream of the rotating wing or wings by rotation about axes substantially parallel to the longitudinal axis of the fuselage and are arranged in pairs relatively to at least one axis of the aircraft in such a manner that at least one stabilizing surface lies on each side of the fuselage and that at least one stabilizing surface lies forwardly and at least one surface rearwardly of the vertical axis of the rotating wing assembly. The lower edges of at least one pair of the stabilizing surfaces, in the position of rest, are not higher than the top of the aircraft fuselage. In Figs. 3, 15 the pairs of stabilizing surfaces 27, 28 and 29, 30 are rotatable on axes 35 which are inclined at a negative angle of incidence to the line of flight and when used in conjunction with a wing of which the inner portion of each blade is set at a small or zero angle of incidence, some of the stabilizing surfaces are arranged outwardly from those portions of the blades. In addition to the stabilizing surfaces, elevators 31, 32 and a rudder 33 are provided for control when flying as an aeroplane. In another arrangement, Fig. 4, one pair of surfaces 44, 45 is mounted centrally and two pairs 40, 41 and 42, 43 are placed forwardly and rearwardly near the fuselage. In a modified arrangement, Fig. 5, the pair of stabilizing surfaces 144, 145 is associated with a pair of surfaces 48, 49 mounted in the plane of the longitudinal axis of the fuselage 34. The elevators 70, 71 may be rotated through 90 and used as stabilizing surfaces in vertical flight. Some of the stabilizing surfaces may be formed of relatively movable parts forming double flaps, or surfaces of inverted T- or V-shape, as described with reference to Figs. 6 to 11 (not shown). In the operating arrangement, Fig. 14 the stabilizing surfaces 54, 55; 56, 57; 58, 59 are operated in pairs from a control wheel 62 and pedals 63 and, in addition, may be selectively operated in conjunction with the control of the elevators 60 and rudder 61. The controls for the stabilizing surfaces may be self-locking, e.g., by means of worm and worm wheel gearing.
