Abstract: 630,079. Thread-advancing reels. NORTH AMERICAN RAYON CORPORATION. Aug. 9, 1946, No. 23687. Convention date, Aug. 9 1945. [Class 120 (ii)] A device for use in the continuous method of producing artificial thread comprises a rotary reel structure, on which the thread is wound, provided about its circumference with movable blades, each of which co-operates with an adjacent relatively stationary rib of the reel structure, and is movable relatively to the rib in longitudinal and radial directions, each blade being a pivoted member of a four-bar linkage, the axes of the pivots being transverse to the direction of its. longitudinal movement, and the blades being moved individually in such a sequence that their combined radial and longitudinal movements outside the stationary ribs effect wrapping and advance of the thread in spaced helical convolutions. The device is supported on a fixed shaft 12 on which are journalled end-plates 10 and 11, secured together by support-members 16, the plate 10 carrying the threadsupporting reel 5. Spiral gears 23 are fixed on the shaft 12 and meshing gears 24, having stud shafts 25, journalled in members 16 rotate about axes at right angles thereto. The gears 24 carry eccentric pivots 28 on which the blades 8 are journalled, this constituting the four-bar linkage. Rotation of the device by crown-wheel 32 and pinion 31 causes the gears 24 to rotate and the blades 8 to perform movements having longitudinal and radial components. The threadcarrying ends of the blades 8, which may be offset, extend through slots in a plate 21, and fit between ribs 17 projecting from a hub carried thereby, the outer edge of the blade 8 being forwardly bevelled at 18, and that of the rib 17 being rearwardly bevelled at 19. Sealing means, such as metal or synthetic rubber bellows 36, or interfitting metal sleeves, are provided where the blades 8 pass through the plate 10 and the space between the plates 10 and 11 is enclosed by a cover 35. The gearing of each blade 8 is so arranged that the blades perform their movements in sequence, each blade in turn lifting the thread 4 from the adjacent surface 19, moving it along the reel, and depositing it again. The device may be used for the treatment of threads such as rayon while they are moving between their points of formation and the position where they are wound into packages. Several such devices may be used in series, and the threads may be stretched by driving them at different speeds. Specification 496,385 is referred to.

Abstract: 788,787. Jet propulsion plant. NAPIER & SON, Ltd., D. Oct. 13, 1955 [Aug. 17, 1954], No. 23968/54. Class 110 (3). [Also in Group XXXIII] An auxiliary jet propulsion engine for use with a rotary wing system comprising a casing of rectangular cross-section and of streamlined shape except for approximately rectangular inlet and outlet openings has closure members pivoted to two opposite sides of the approximately rectangular inlet and outlet openings so that in the " open " position, the openings are free for the entry of air and the passage of the reaction jet and in the " closed " position they close the openings and form with the casing a substantially closed completely independently streamlined body. A streamlined shape is defined as a shape having low drag at its normal operating speeds. The invention is described with reference to a ram jet unit having a casing 1 of approximately rectangular cross-section disposed with its major axis horizontal in the rotary wing system of a helicopter. The casing has inner and outer walls 2, 3 and, at its inlet end, a substantially rectangular air inlet opening leading through a short approximately parallel or slightly expanding passage 4 formed by the wall 2 into an expanding section 5 constituting the forward end of the combustion chamber 6. The chamber 6 is followed by a contracting outlet passage 7 terminating in an approximately rectangular opening 8. A rectangular flame tube 9 is mounted in the combustion chamber 6. The forward portions of the upper and lower walls of the passage 4 are formed with two part cylindrical recesses 10. Pivoted on a horizontal axis midway between the upper and lower walls of the passage are a pair of closure members 11. When the closure members are in the " closed " position shown, they block the inlet opening and form a substantially cylindrical nose for the casing. When in the " open " position, the flat surfaces of the closure members form part of the inlet opening. Two flap-like closure members 12 are pivoted to the upper and lower edges of the rectangular outlet opening 8. When the members 12 are in the " closed " position shown, the block and the nozzle form part of the faired exterior of the casing 1. The closure members 11, 12 are operated by a servomotor 14. This servomotor is actuated by the supply of fuel to the combustion chamber of the ram jet so that when fuel is supplied to the burners through the conduit 25, the fuel pressure acting through the conduit 24 moves the piston 15 to the right and opens the closure members. The jet propulsion unit may be of the compressor-turbine type.
