Filed: 1926-03-03
Abstract: 248,753. British Thomson-Houston Co., Ltd., (Assignees of Clarkson, W. 13.). March 3, 1925, [Convention date]. Heating by electricity.-An arc welding system having means for producing a relative transverse motion between the work and the arc is provided with means responsive to the condition of the arc for causing a limited reverse traverse movement when the arc fails. The work 10 and electrode 11 are connected to supply leads 19, 20. When the starting control 24 is closed the motor 15 feeds the electrode into contact with the work and the coil 29 then moves contactors 27, 28 into their upper position with consequent reversal of electrode motor. When the arc is of the required length the coil 33 raises contactors 31, 32 and the motor 15 feeds the electrode to keep the arc length constant. The contactor 32 completes the circuit of the coil 37 which raises contactors 35 and 36 with consequent operation ot the traverse motor 57 to advance the work and closure of the delay action switch 48. If the arc fails the coils 32, 37, 42 become deenergized with temperorary energization of coil 41 and raising of contactor 39 to reverse the traverse motor until the delay action switch opens. The switch 52 may be shifted to the upper position to cause operation of the work in the opposite direction under the control of coils 41, 47. The switch 51 may be moved to its upper position to shunt the contactor 32 and by operating the switch 50 the traverse motor can be stopped and started independently of the device 30.

Title: Improved method and apparatus for treating artificial yarn to simulate spun staple yarn, and yarn so treated
IPC: D02G1/16
Filed: 1954-03-02
Abstract: 767,835. Finishing yarns and threads; thread-guides. ALGEMENE KUNSTZIJDE UNIE N.V. March 2, 1954 [May 12, 1953], No. 6143/54. Classes 120 (2) and 120 (3). Bulked yarn i.e. filamentary yarn in which individual filaments comprise loops formed at random, is produced by propelling a twisted artificial yarn through a confined zone by means of a high velocity gas stream and changing the direction of travel of the yarn and reducing its speed without applying further twist after leaving the zone. As shown in Fig. 1, yarn 11 passes to a suction device 13 in which it is caught by a gas e.g. air, supplied through a tube 14 and propelled through a tube 15: the yarn emerging from the tube 15 is deflected by a baffle 16 (or a thread guide 25, Fig. 2, or a sphere 33, Fig. 3 (not shown)), whilst still under the turbulence created by the gas blast and is wound by a device 19 at a speed less (at least 5 per cent.) than the speed at which it is taken off at 10 so that some slack develops near the baffle. This speed ratio is controlled and compensation made for variation in the speed of take up of the bulked yarn in the apparatus of Figs. 4 and 5. Yarn 40 is drawn from a supply 41 by a feed roller 42 and, on issuing from a suction device 43, is deflected by a baffle 45 and passes through guides 46, 47, 48, to a spool 49 rotating on a driven spindle 52: the roll 42 is arranged on a roller 50 mounted on a movable arm 51 and driven by the spool 49 or the yarn package thereon. A quickdrying lacquer may be applied temporarily to the yarn at any stage of the treatment to maintain the loops.

Title: Thrust reversing device for turbojet aircraft engines
Inventor: PARKER ARNOLD GEORGE
IPC: F02K1/62
Filed: 1959-02-23
Abstract: 911,202. Jet-propulsion plant. CANADAIR Ltd. Feb. 23, 1959, No. 6152/59. Class 110 (3). [Also in Group XXXIII] A turbo-jet engine for aircraft provided with a thrust reversing and noise suppression device has a variable area orifice nozzle from which the exhaust gases from the engine are exhausted, the variable area orifice nozzle being effective to corrugate the surface of the stream of exhaust gases, and means to cool the corrugated surface of the exhaust gases. A cowling structure which surrounds and extends aft of the jet pipe and nozzle comprises an engine cowl 13 spaced from the jet pipe and formed at its rear end with an annular flange for the attachment of a flange 18 to which are secured an outer fairing panel 19 and a pair of inner cranked panels, one attached at its rear edge to the trailing edge 22 of the nozzle and the other, 26, being extended to and attached to the trailing edge of panel 19, the cranked portions of the panels forming between them a plurality of openings 25a. The openings 25a are partly closed by plates 45 mounted on arms 53 pivoted at 53a and each connected by a link 46 to a toggle mechanism 39 operatively associated with a jack 43. The toggle mechanisms are associated also with a plurality of sector-shaped flaps 30 each mounted at its outer edge by a hinge 31 to panel 26 to move between the outer positions shown in Fig. 3, substantially parallel with the engine axis to allow free-flow of the propulsive jet to the positions shown in Fig. 4 in which they blank-off the jet pipe. The flaps 30 are connected together along radial hinge lines by V-section projections 33, each formed with a leading apex and an aft-base which co-operates with a leading base on a similar projection fixed to the inner wall of the rear end of panel 26 thereby forming as in Fig. 3 a plurality of circumferentially spaced projections or corrugations for reducing noise in the jet. Operation of jacks 43 'causes the flaps 30 and plates 45 to take up the positions shown in Fig. 4, whereby the jet is deflected forwardly and outwardly through openings 25a. Such deflection is assisted by blowing jets of air in radially opposite directions from a transverse duct 55 positioned within a fairing 58, 59. The trailing edge of nozzle 10 is formed with apertures 24 through which cooling air is delivered through an aperture 50 in flange 18 by means of a duct 11 communicating at its forward end with a rear compressor stage or a ram air intake in the engine cowling. The trailing edge of panel 26 is apertured at 52 in order that cooling air may be directed on to the corrugated jet by drawing air into openings 25a during normal propulsive thrust.
