Title: Gas turbine engine exhaust nozzles
IPC: F02K1/46
Filed: 1971-04-19
Abstract: 1335724 Jet propulsion nozzle GENERAL ELECTRIC CO 19 April 1971 [27 April 1970] 20008/71 Heading F1J Gas turbine engine exhaust nozzle has a number of cones 26 around the periphery of the downstream end, the length of the cones being greatest at the top of the nozzle and the cones causing the jet stream to break up into plumes each attached to one cone. The cones act as an acoustic lens for the jet wake of an aircraft and deflects the angle of maximum noise upwardly so that the path length to ground is increased and there is greater attenuation in noise intensity at ground level. The base of each cone (as seen in cross-section) is faired into the exhaust nozzle wall, and the apex of the cone is at, or down-  stream of the downstream end of the nozzle. At least one of the cones is movable axially to an optimum position for producing the desired change of direction and this also provides a means of adjusting the pressure ratio across the nozzle. The most efficient sound reduction occurs when the cones are spaced one diameter apart and they may be so positioned around a circular section nozzle or along the longer sides of a rectangular nozzle.  In a high-by-pass fan-type engine, cones are provided at the downstream end of the fan duct and at the downstream end of the jet nozzle.

Abstract: 481,402. Projectile fuzes. JUNGHANS, H., and JUNGHANS AKT.-GES., GEB. July 20, 1937, No. 20033. Convention date, July 23, 1936. [Class 9 (i)] A centrifugal drive for clockwork projectile fuzes comprises a secondary centrifugal weight adapted to assist the initial action of a primary centrifugal weight by pushing the primary weight outwards but reaching the limit of its travel before the primary weight. As shown, the toothed segments a<1>, which are pivoted at a and drive the clockwork mechanism by way of the toothed shaft f, each carry a primary centrifugal weight b. About each pivot a there is also mounted a lever c which carries a secondary weight d and is provided at its opposite end with a projection e by means of which each lever c bears against the respective primary weight b when the operating mechanism is in the condition of rest. When the projectile is fired, the levers c, owing to the secondary weights d, press forcibly with the projections e against the weights b and assist the outward movement of the latter until the weights d reach their extreme positions. When this position is reached, the weights d remain stationary and the primary weights b continue to move outwards, the projections e no longer contacting therewith and the effect of the auxiliary force of the secondary weights d on the primary weights b ceasing.

Title: Improvements in and relating to machines for the manufacture of electric incandescent lamps
IPC: H01K3/10
Filed: 1936-07-20
Abstract: 467,876. Supports for electric incandescent lamp filaments. GENERAL ELECTRIC CO., Ltd. July 20, 1936, No. 20053. Convention date, July 19, 1935. [Class 39 (ii)] In a machine for inserting filament supporting wires into a glass stud provided at the end of a supporting-stem, of the kind wherein the wires are drawn from a coil and their forward end is inserted into the glass stud, the wires then being cut to the required length and their free ends shaped into an open eye which is closed after the insertion of a filament therein, a vertically movable bifurcated rod 10, Fig. 2, is associated with each wire 7 which is located between its arms, the junction of the arms being formed as a cutter 12 which co-operates with a cutter 13 slidably mounted on the bifurcated arms, so that the free end of the severed wire 14 is bent downwardly, whereupon the end 15 of a pivoted lever 16 engages the bent end and forces it into an aperture 20 in the cutter 13, thus forming an open eye of the form shown in Fig. 10. A pair of leading-in wires are sealed into the stem of the lamp, and a filament secured between their ends before the radial filament supports are secured in position, so that the filament is hanging in readiness for. attachment to the supports after the formation of the eyes therein. The insertion of the filament into the open eyes is effected at the next operative position of the machine by mechanism comprising a cylindrical frame 21, Fig. 4, supporting an annular member 22 formed with bosses 38 to support the eyes at the ends of the carrier wires 14 mounted on the lamp stem. Within the member 21 are located four forks 27 and an arm 28 which have resilient lower portions secured to a stationary member 26 and co-operating with the periphery of a disc-shaped cam 25 at the upper end of a vertically movable shaft 24. When the lamp mount enters this working position a jet of air from a nozzle 36 blows the filament 5, hanging downwardly from the leading-in wires, into an approximately horizontal position. The mount is then lowered so that the filament slides down the prongs 37 of the forks 27 on to the bosses 38, whereupon cam 25 is moved upwardly, causing the prongs 37<1> of the forks to extend the filament outwardly and into the open eyes 14<1> of the supporting wires 14, as shown in Fig. 7. The eyes are then closed upon the filament by pressing upon them the ends 31 of pivoted levers 30 which are actuated by the vertical movement of a frame 33 which surrounds the frame 21, and is provided with horizontal slots 32 within which the outer ends of the levers 30 are journalled. The levers are thus swung into a horizontal position, the actual closing of the eyes being effected by the pull of springs 34 on the levers. The bosses 38 and the undersides of the ends 31 of the levers may be corrugated to prevent lateral movement of the eyes during clamping. The upper end of the resilient arm 28 carries two forks 29 which hold the leading-in wires 4, 4 in position while the eyes are being closed.
