Abstract: 878,191. Jet-propulsion nozzles. VICKERS AIRCRAFT HOLDINGS Ltd., and RICHARDS, E. J. Oct. 14, 1959 [Aug. 18, 1958], No. 26462/58. Class 110 (3). In a gas-turbine jet-propulsion engine, the jet nozzle outlet has a large width to depth ratio, and the nozzle is combined with an air-induction casing arranged to surround the nozzle and of such a length as to cause ambient air to be drawn in and entrained with the gas discharge. The propulsion nozzle 10 is of circular section at its upstream end 101 and of rectangular section at its outlet 102. The nozzle is enclosed within a nacelle 11, the upper and lower walls of which terminate at 111, while the side walls thereof terminate level with the nozzle outlet 102. The air induction casing associated with the nozzle is shown in its retracted or inoperative position in Fig. 1 in full lines and in its projected or effective position in chain-dotted lines, and comprises upper and lower fairing members 15 and side plates 14 connected together to form an open-ended casing which is disposed around the nozzle 10. The upper and lower members 15 are of aerofoil or tapered cross-section and when in the projected position afford, together with upper and lower edges of the nozzle 10, openings C through which air is drawn to be entrained with the discharging gases thereby producing a noise suppression effect. The side plates 14 of the induction casing are disposed in the spaces between the side walls 112 of the nacelle and the side walls of the nozzle and are supported by means of rollers 13 which are movable in channel-section members 12 secured one to each of the side walls 112. A cable 17 is secured to the rollers 13 and threaded around pulleys 16, the movable element 181 of a fluid-pressure pressure ram 18 being connected to the cable, so that movement of the ram in the direction B causes the induction casing to be moved from the retracted to the projected position. The jet nozzle may be of elliptical instead of rectangular section; also a series of nozzles may be disposed side-by-side, a single induction casing being associated with the nozzles.

Abstract: 813,137. Stretching textile threads. ONDERZOEKINGSINSTITUUT RESEARCH N. V. Aug. 31, 1956 [Sept. 12, 1955], No. 26647/56. Class 120(2) In a ring and traveller type stretching and twisting machine each ring is freely movable in an upward direction and may be locked in a position above its traversing trajectory. Thread 1 to be stretched is fed over thread guides 2, 6, 8 and 9 to the traveller 10 while the ring 11 is in a raised position due to a spring 22 engaging a notch 27 on one of the rods 13, and unstretched thread is thus wound on a cylindrical member 40 attached to a centring cap 36 at the top of a tube 32. The thread is then wrapped several times about a driven stretching roller 7 and guide roller 8 and the spring 22 is released to allow the ring to fall on to the reciprocating ring rail 18 so that stretched thread is wound on the tube 32. On completion of winding the thread between the cylinder 40 and the tube 32 is severed and the completed package removed. The unstretched thread on the cylinder 40 is removed by running a knife through a groove 41 thereof: Alternatively, the centring cap 36 and cylinder 40 may be formed integrally with the tube 32 and the length of tube so arranged that the unstretched and stretched parts of thread are adjacent on the completed package. The centring cap 36 and a similar member 31 are formed with annular grooves 38, 34 containing rings 39, 35 of rubber which, when the spindle is stationary are completely sunk in the grooves 38, 34, but expand under centrifugal force when the spindle rotates to hold the tube 32 on the spindle 29.

Filed: 1966-06-15
Abstract: 1,194,182. Flanging; making pipe fittings. BTR INDUSTRIES Ltd. 13 June, 1967 [15 June, 1966], No. 26777/66. Headings B3A and B3Q. [Also in Division F2] A method of joining together two tubes 1, 3 to form a branched fitting comprises making a hole 2 in a wall of one of the tubes 1, forming an outwardly directed flange 4 around the hole, and then locating an end portion of the second tube 3 around the outer periphery of the flange 4 and attaching said end portion to the flange. As shown, the pipe material around the hole 2 of a thin-walled metal pipe 1 is drawn outwardly to form an upstanding flange 4 and the second tube 3, with a knurled surface 10 and end flanges 11, 12, is fitted around, and brazed to, the flange 4, a step 13 being formed in the inner periphery of the flange 12 to receive the flange 4 so that the latter lies flush with the inner surface of the tube 3. The tube 1 is first placed in a two-part clamp 20, 21, having a circular guide hole 22 in the upper part 21, the tube being located in the clamp by a locator (23), Fig. 6, not shown, having a spigot (24) with the same cross-section as the hole 2. The locator (23) is withdrawn, whereupon a drawing member 26, having a sliding fit, is inserted in the tube 1 with a cylindrical hole 28, and a drawing plug 29 accommodated therein, located below the hole 2. A draw bar 30 is inserted into the hole 22 and twisted to make screw-threaded engagement with the drawing plug 29 which has a tapered upper face so that, withdrawal upwardly of the bar 30 in the guide hole 22, gradually upsets the material around the hole 2 to form the flange 2. The opening 22 has a portion 33 of reduced diameter to support the flange 4 as it is drawn. In a modification the apparatus is adapted to form a flange for connecting tubes at angles other than 90 degrees.
