Abstract: 529,824. Weft-feeler arrangements for looms. SMITH, R. H., and SHACKLETON, G. W. June 9, 1939, No. 16885. [Class 142 (iii)] Relates to detector mechanism for multiple shuttle looms in which a detector b, b'...b3 is mounted in connection with each cell a, a<SP>1</SP>...a<SP>3</SP> of the shuttle box. The selecting device comprising a vertically movable rod 5 is moved prior to the movement of the required cell into working position to allow only the detector of that cell to enter fully its shuttle. If the weft on the bobbin of the shuttle is depleted the detector, e.g,. b is permitted to move so far that a disc d' mounted thereon moves into the path of a bar 8a, causing a lever 11 to take the position shown in full lines, so that upon forward movement of the sley the lever 11 strikes a member 12 to stop the loom or to put into action mechanism for substituting a weftcharged shuttle. The rod 5 has spaced projections 5a so disposed with respect to discs d on the detectors that in any position of adjustment of the rod, one only of the detectors can move fully into its shuttle. A bar 7a is moved by a cam actuated rod 6 when the loom is in motion to a position to engage the discs d to move and retain the detectors clear of the shuttles until the shuttle returns to its cell and is at rest.

Filed: 1967-04-13
Abstract: 1,133,700. Shoots; coin-packaging machines. I. UCHIDA. 13 April, 1967 [3 Nov., 1966], No. 17108/67. Headings B8C and B8S. [Also in Division G4] Coin-counting apparatus can deliver coins into a first position 52 where a batch of coins is wrapped or a second position where they are delivered to a bag 80, Fig. 8. Assorted coins in a hopper 1 are moved by centrifugal action to the periphery, small coins discharging through a gap between 1 and 3, Fig. 2. Coins 2 of the prescribed size are advanced by a continuously driven rubber roller 13 so as to engage in recesses 4a, so driving wheels 4, 6, 7 to advance counter 9. The wheel 4 is on a shaft with a gear 10, Fig. 5, so controlled by a one-rotation device, comprising gear 12, slot 17 and a lever (19) (Fig. 7), that after fifty coins have been delivered a switch opens and the drive stops. For such an operation the delivery shoot is as shown in full lines in Fig. 8 and the coins fall into a cylinder 52. The coins are then wrapped in known manner. An electromagnet restores the lever (19) so that another operation can ensue. To deliver more than fifty coins a knob (37) is turned to adjust a gear 30, Fig. 5. At the same time a lock 59, 60 is released and a lever 68 is rocked to bring the shoot 55 into an inclined position, whereby coins are fed into a bag 80. A slide 22 prevents the end of lever (19) engaging slot 17 so that gear 12 is permitted to make more than one revolution, transfer to gear 30 being effected by pin 32. If the coins are not to be batched but merely counted, gear 30 is turned so that gap 30a lies in the path of pin 32.

Title: Combustion chamber for a gas turbine engine
Inventor: DAKIN ROBIN MICHAEL
IPC: F23R3/14
Filed: 1966-04-20
Abstract: 1,135,670. Gas turbine combustion chambers. BRISTOL SIDDELEY ENGINES Ltd. April 7, 1967 [April 20, 1966], No. 17196/66. Heading F1L. An annular or, as shown, cylindrical flame tube for a gas turbine engine combustion chamber comprises an upstream end wall formed from a number of coaxial frusto-conical rings 5, 6, 7, 8, spaced apart radially from one another with a portion adjacent the downstream end of each ring 5, 6, 7 inserted within an adjacent upstream end portion of the next radially-outer ring 6, 7, 8, whereby the rings partially overlap, the portions of the frusto-conical surfaces exposed to the interior of the flame tube together defining the concave inner surface of the end wall and the overlapping portions of each pair of adjacent rings defining an annular passage 10, 11, 12, open at each end thereof, through which cooling air from a space 14 is introduced into the flame tube, the flame tube also including vanes 16 having tongues 20 engaged in slots 21 in the rings to support the rings. Since the core angles of successive rings 5, 6, 7, 8 are of decreasing magnitude, the cooling air is constrained to flow in intimate contact with the downstream portion of the internal surface of the rings 6, 7, 8. The vanes 16 are disposed at an angle to the radial direction so as to impart swirl to the cooling air in the same direction as that imparted to the combustion air by vanes 4. The tongues 20 are welded into the slots 21 and the vanes 16 are similarly welded to an extension 15 of the cylindrical flame tube wall 1 at slots 27. The vanes 4 are carried by an annular spigot 9 of the ring 5. If the ring 5 becomes detached from the vanes 16, its axial movement is limited by the engagement of a flange 19 with a wire ring 18 welded or brazed to the vanes 16. Similarly, if other rings become detached, ring 5 limits axial movement of ring 6, which in turn limits axial movement of ring 7. If a vane 16 becomes detached, it lodges against an adjacent vane without materially affecting the cooling air flow. Cooling air also flows through the space between ring 8 and a cylindrical ring 22 attached to the extension 15 and through a circumferential series of holes 23 in the ring 22.

Abstract: 118,528. McKean, J. O. Nov. 26, 1917. Winding-machines; thread-guides; stop-apparatus, non-automatic.-In a quick-traverse machine building a cop according to the " Fiji " wind, the traverse frame swings freely outwards, but is prevented from inward movement by a member which is supported by the arbor carrying the traverse cam and the swinging thread-guide and which engages a stop connected to and moving with the thread-guide. A fixed arbor 14, Fig. 1, supports the traverse cam 16, and a frame 11, which carries in arms 10 the rod 9 along which the guide 7 is reciprocated by the cam. The frame. 11 carries a stop 41, Fig. 2, which is engaged by a member 39 which slides by gravity through a vertical slot 38 in the end of the arbor 14. As the cop grows, the thread-guide 7 and frame 11 are pushed aside and the stop 41 moves and allows the member to fall gradually. The cam 16 is driven from the fast pulley 4 through a belt 29 and gearing 26, 17. The pulleys 4, 28 are coned slightly, and the belt can be adjusted by a screw 32 to adjust the relative speeds of the spindle 1 and the traverse. The frame 11 is weighted at 45 to tend to press the thread-guide against the cop, and stops 53, 55 on the frame 11 limit its movement by engagement with a lug 54. The thread-guide 7 is mounted on a light tube 8 and is made of thin metal. It extends through a slot in a casting 47 secured to the traverse bar 9 and is supported by a rail 50 mounted on the casting. The machine is started by moving the belt 6 from the loose pulley 5 to the fast-pulley 4 by means of a handle 91 acting through a lever 84 and link 85. A spring 90 tends to hold the belt on the loose pulley, and a catch 80, 81 at the end of an arm 82 holds the belt on the fast pulley against the action of the spring.

A bottle carrier comprising a ring 22 to encircle a flanged bottle neck below the flange 14, and a U-shaped handle 20, the bight 38 of which constitutes a carrying bail and the legs of which extend down to engage the ring, the ring comprising opposite arcuate reaches 26, 28 each shaped to encircle half the neck, has a first, permanent, interlocking, articulated connection between one leg 40 and a first, resilient, permanent connection 24 between ends of the reaches 26, 28, and a second articulated connection between the other leg 48 and a second connection between the reaches, this second reach connection being detachable to permit assembly with a bottle, the two articulated connections rendering the carrier inoperative if the ring is assembled wrong side up on a bottle. A loop 42 at the end of the leg 40 is closed round the upper arm 44-of the loop 24 which forms the first reach connection. The lower arm of the loop 24 limits the movement of the leg 40. The reaches 26, 28 are formed at their ends with loops 72, 70 respectively. A loop 56 bent so as to leave a small gap between its end 84 and the leg 48 encircles the reach 26 adjacent the loop 72. The carrier is assembled on to the neck of the bottle, Fig. 14, with the reaches 26, 28 free to be pressed apart so as to be pushed over the flange 14. The assembly of the carrier is completed, Figs. 15, 16 by turning the handle in a clockwise direction, which movement forces the loop 70 over the loop 72. The ring tightens on the bottle neck and the end 84 of the loop 56 is forced away, Figs. 15, 16, to allow the loop 70 to be pressed down beside the loop 72, completing the assembly, Fig. 13. If the carrier is assembled wrong side up on a bottle rotation of the handle in one direction is prevented by the connection 24, and rotation in the other direction does not perform the operation of locking the loops 70, 72 together is described above. Interlocking means other than the loops 70, 72 are described, one from comprising a hook and eye arrangement, and another a loop similar to the loop 24, on oblique cut enabling the sides of the loop to be drawn apart to assemble the carrier to a bottle.
