Title: Improvements in aeroplanes
Inventor: WALLIS BARNES NEVILLE
IPC: B64C3/40
Filed: 1959-06-02
Abstract: 885,033. Variable sweepwing aircraft. VICKERS AIRCRAFT HOLDINGS Ltd. June 2, 1960 [June 2, 1959], No. 18883/59. Class 4. An aeroplane has means for balancing the moments developed on the wings by forces acting thereon in the direction of flight, the means being sensitive to disparity between such moments, and effective to operate a directional control organ. The aircraft of Fig. 1 comprise a fore-wing A, and two variable sweep wings B pivoted to the fore-wing at C. Each wing B mounts jet propulsion engines D pivoted to the wings about axes E. In Fig. 2 each wing is secured to a toothed sector F concentric with the pivoting axis of the wing, and meshing with a rack G. Each rack is attached to an arm MA of a lever M pivotally mounted on a nut H to swing between stops N. A lead screw J engages nut H and is drivable by a reversible motor (not shown) through gearing K. The two racks G are connected by straps L each having an upper roller LA and a lower roller (not shown) received in guide grooves in the fuselage (not shown). Rotation of the lead screw traverses nut H to rotate the gear sectors and wings. If the moments on the two wings in the direction of flight are not equal, e.g. due to failure of one engine or higher drag on one wing, when trailing edge flaps are operated lever M is swung to abut one or other of stops N, and this actuates a microswitch or valve to operate a yaw trim control, e.g. a rudder, a wing tip fin, or an engine rotable about a vertical axis.

Title: Improvements in photographic cameras
IPC: G03B19/02
Filed: 1935-07-03
Abstract: 459,167. Multiple-photograph cameras. ECKERT, H. G., 51, Caversham Road, Kentish Town, and STORE STUDIOS, Ltd., 89, Wigmore Street, Cavendish Square, both in London. July 3, 1935, No. 19035. [Class 98 (i)] In a camera having means for moving the plate holder into a series of different positions, the supporting member for the plate holder carries a series of horizontal slots which are successively engaged by the pin of a rotating lever, and one or more slots arranged at right angles to the others which are engaged by the pin to change from one row to the other during the traversal of the support. The frame 15 held by vertical walls 10, 12 has vertical rods 16 connected together by a tubular member 17 which is slidable on a horizontal rod 18. Two cross-bars 20 sliding on the rods 16 support the plate carrier 21 and slot carrier 22. A spring 25 counterbalances the weight of the carriers. Spring-pressed detents co-operate with notches 27, 30 in the vertical and horizontal members in order to locate the positions of the plate holder. The panel 22 carries a number of metal channels 31 ... 38, and a frame member 39 carries a shaft 40 having a crank 41 and pin 42 fixed thereon. A handle 44 on the shaft 40 is held by a pawl 46. When the pawl is released and the shaft 40 rotated, the pin 42 engages the slot 31, and lifts the plate carrier through one picture depth where it is held by a detent in position for another exposure. A further rotation of the crank 41 brings the pin 42 into engagement with a slot 32. At the end of the upward movement of the plate holder, the pin engages the slot 33 and moves the plate holder aside through one picture width. At the end of the downward movement, the pin engages a vertical slot 50 which is movable across the slot 35 under the action of a spring 51. The pin enters the blind part 52 of slot 50 and moves the plate holder aside into another exposure position. The crank. is then rotated to engage the opposite end of slot 35, and commence the upward movement of the plate holder at the last position, or pins 7 engages a pivoted stop member 58 to bring its end 60 into the path of the crank 41, preventing further clockwise rotation. The carriage is moved to the right to release the stop and allow the cycle to be repeated.

Title: Improvements in or relating to balling machines for twine and the like
IPC: B65H54/64
Filed: 1931-07-02
Abstract: 379,452. Balling-machines for twine &c. BYWATER, Ltd., W., BYWATER, W. B., RIMINGTON, K. T. 13., and CLAYTON, W., Kidson Street, Sweet Street, Holbeck, Leeds. July 2, 1931, No. 19049. [Class 120 (ii).] In a balling-machine of the kind wherein twine is wound by a revolving flyer on to a rotating peg which is adjusted angularly relatively to the flyer axis so as to build up the ball of twine, the rotating peg drives a cam &c. and thereby effects its own angular adjustment, the cam also actuating a change speed motion to reduce the speed of rotation of the peg when the latter comes into a predetermined angular position during the adjustment. A number of flyers 3, Fig. 1, are arranged at intervals along a machine frame 19 and driven directly from a main shaft 5, each flyer being associated with one of a number of pegs 7 mounted on a common head 8 pivoted in bearings 9 in the frame. A pinion 14, Fig. 3, keyed to a shaft 15 coaxial with the bearings 9, is geared to a shaft 12 which is rotatable in the head 8 and drives the peg spindles 10 through worm gearing 11, an end spindle driving a shaft carrying a cam 16 which engages a bowl 18 on the main frame to control the angular position of the head 8 and pegs 7. The main shaft 5 drives a gear 21, Fig. 4, to which the shaft 15 is adapted to be operatively coupled, either directly or through reduction gears 22, 23 by a clutch member 24 on a lever 25. A toothed segment 28 rigid with the lever 25 is engaged by a weighted rack bar 29 which normallv is maintained in a raised position, to keep the clutch member 24 in direct engagement with the gear 21, by a bar 32 but when the outer close wind is to be applied to the ball, a pin 16x on the cam 16 raises a rod 31 from engagement with the bar 32 and a spring 33 attached thereto removes a support 30 from beneath the rack bar, allowing it to fall and bring the clutch member into engagement with the gear 22. When the ball is completed, the cam 16 rocks a lever 34, which normally locks a spring-controlled belt-bar, permitting the bar to move the driving belt on to a loose pulley and stop the machine. The twine is fed around a pulley 36 on a weighted segment 37 which drops on to a rod 38 associated with the lever 34 to rock it and stop the machine when the twine breaks or the supply fails.

Filed: 1928-07-03
Abstract: 320,070. Lindemann, F. A. July 3, 1928. Vacuum tubes.-Apparatus for recording or detecting variations in electric current strength, for example for recording sound vibrations, consists of a glow discharge lamp containing an anode 14, Fig. 1, and a narrow elongated cathode 12, a screen such as a film 21, Fig. 2, and projecting means such as a lens 20, which faces the cathode directly, and projects an image of the whole width of the glow upon the screen, with or without means for blocking out more or less of the length of the image. The cathode may consist of a wire of constant or varying diameter partly surrounded for the whole of its length by a glass shield 13; it may be polished to make the glow uniform. The anode, consisting of a wire or metal sheet, may be arranged, as shown, closer to the cathode at one end than the other. Variations in the current strength produce variations of the glowing length of the cathode without variations of the intensity of the glow; when the anode is mounted parallel with the cathode, variations in current produce variations in the intensity of luminosity of the cathode. The envelope is made of glass or fused silica transparent to visible and preferably also to ultra-violet rays. Specifications 206,908. 209,800 and 212,867 are referred to.
