Title: Improvements in or relating to latch gear for folding wing aircraft
IPC: B64C3/56
Filed: 1933-08-17
Abstract: 418,776. Aircraft wings. BLACKBURN AEROPLANE & MOTOR CO., Ltd., Seaplane Base, and PETTY, G. E., Pantiles, both in Brough, near Hull. Aug. 17, 1933, No. 22971. [Class 4.] In aircraft having wings hinged to the fuselage to facilitate folding and latches for maintaining the wings in their flying position a fluid-pressure. operated control is provided for effecting movement of the latches into and out of their operative positions. As shown and as applied to a biplane, a reservoir 10 communicates by means of a conduit 12 with pumps 13, 113 mounted on the centre section 14 of the lower wing and controlling, respectively the latches on the port and starboard side of the aircraft. The pumps 13, 113 communicate, respectively, with cylinders 16, 116 on the lower wings and cylinders 17, 117 on the upper wings. The various pipes pass up the front of the fairings of wing-struts 20, 120, 22, 122. The rear spar 23 of each wing is provided with a hinged joint 24 and the front spar with a joint 27, 28 held in operative position by a latch pin 29 constituting an extension of a plunger 30 movable within, e.g. the cylinder 16. The latchoperating mechanism for the upper wing is located on the movable part of the wing, the fluid supply conduit for the cylinder 17 being looped behind the rear wing spar. When the handle of a pump 13 is pulled, fluid passes into the cylinders 16, 17 through pairs of admission vents 36, 136 to force pistons 37 on the plungers 30 to the left against the action of a pair of springs 33, 34 to withdraw the latch pins. Each plunger carries screw-threaded extensions 38 provided with a stop collar 39 which co-operates with a safety trigger 40 which is released on actuation of the pump by movement under fluid-pressure of a piston 46 against the action of a spring 48. The stop-collar 39 is screwed onto the extension 38 and is locked in position by a nut 51 ; thus on failure of the hydraulic gear the latches may be withdrawn by removal of the nut 51 and rotation of the stop collar. Return of the latch pins may be assisted by hydraulic means, the pumps may be locked so as to hold the latches inoperative, and the apparatus may be applied to a monoplane.

Title: Flame retardant treatment of polyamide fibre material
IPC: D06M101/16
Filed: 1973-05-15
Abstract: 1474031 Flame retardant treatment of polyamides IWS NOMINEE CO Ltd 1 May 1974 [15 May 1973] 23119/73 Headings DIB and DIP [Also in Division C3] A process of improving the flame-resistance of polyamide fibre materials comprises treating the material under acid conditions (pH below 3.5) with an anionic complex of tungsten and with an anionic complex of zirconium or titanium. The finish has improved fastness to alkalies, washing and UV light. The process may be carried out simultaneously with dyeing, e.g. with acid levelling or 1:1 premetallised dyes. The tungsten complex is preferably an isopolytungstate or heteropolytungstate formed by acidifying an aqueous solution of sodium tungstate, with e.g. phosphoric, boric, formic, citric, oxalic, or tartaric acid (formation of heteropolytungstate). The solution is preferably applied at a temperature of at least 30C for at least 10 minutes. The zirconium or titanium complex may be a fluoro-, carboxylato-, or hydroxycarboxylato zirconate or titanate. The treatment may be applied to natural polyamides, e.g. wool, silk, alpaca, cashmere, mohair, leather or natural hair, e.g. wigs, and particularly to wool in blends containing less than 85% wool, e.g. with rayon. nylon, polyester, or polyacrylic and to wool which has been subjected to a resin treatment, e.g. with a blocked isocyanate, a polyamineepichlorohydrin resin or a silicone. The wool fibres may also be blended with asbestos. glass or "Nomex" (RTM) fibres. The material may be in_the form of yarn, or woven, knitted or pile fabric. In one Example the process is followed by a silicone treatment, and in others it is preceded by a resin shrink-resist treatment. Specifications 1372694 and 1379752 are referred to.

A machine tool 1, Fig. 1, for turning pistons 20, in which the tool 78 can be moved in an elliptical path, comprises a fixture 4, Fig. 6, for the piston, movable relative to a tool head 10 by a rod 3, a bar 6 actuated by a cam 5 on the rod, which controls a draw bar 16, and a motor 7 which rotates the sleeve 18, and the head 10, through a belt 8. Tool head 10 comprises a housing 22, Fig. 1, secured to rotary sleeve 18, a bar 24 connected to draw-bar 16, and slidable in stationary sleeve 14, a collar 28 attached to sleeve 14, a sleeve 42 pivoted at 48 to a collar 28, and to bar 24; and a tool-holder 74 connected to bar 24 by a link 90, and to sleeve 42 by links 70. Bar 24 has an elongated slot 50 therein, to allow axial movement thereof, and the bar carries a cam follower 56 which cooperates with an inclined slotted cam 58 inserted in a pocket 60 in sleeve 42. Toolholder 74 is mounted in housing 22 by an eccentric pivot 76, and link 90 is adjustably clamped to the eccentric by a screw 86. In operation, when turning an elliptical piston skirt, the draw-bar is moved downwardly to the Fig. 1 position. Sleeve 42 is therefore inclined due to the cam engagement 56, 58, so that linkage 70 is inclined with respect to plane 71, by an angle B. The head 10 is rotated, and due to the fact that collar 64 rotates in plane 71, the tool 78 moves in an elliptical path. The shape of the ellipse is governed by the inclination of slotted cam 58, and the position of follower 56 in the slot, when drawbar 16 is held against axial movement. The depth of cut can be altered by pivoting eccentric 76 to produce a flared skirt on the piston, by moving the draw-bar axially, and the skirt can be rounded by providing a suitable cam 5. The tool 78 can produce a circular skirt when the draw-bar is fully retracted. In a modification, the tool head 10 can be moved relative to the piston 20, and a second tool 78 can be provided, so that a roughing and finishing operation can be performed.

Abstract: 1303234 Forming rivets in sheet material; riveting ALUMINUM CO OF AMERICA 19 April 1971 [18 March 1970] 23776/71 Headings B3A and B3U A method of forming an integral rivet in a sheet element 2 comprises placing the sheet element between male and female dies 4, 6, moving the dies together to form a hollow boss, continuing movement of the male die cornpressively thins an annular portion 50 of a lower sector of said hollow boss by establishing metal flow substantially entirely in the direction of the upper extremity of the hollow boss so that this part of the hollow boss is substantially equal to the thickness of the remainder of the sheet material and subsequently forming the hollow boss to establish a hollow rivet. To form the rivet the hollow boss is placed between male die 62 and female die 70, which when moved together form a rivet 60 with the annular thinned portion forming no part of the rivet. The sheet element may be adapted to serve as a container wall in which case a tab element 90 may be required to be attached to the rivet. A staking anvil 92 and a staking punch 102 surrounded by a relatively movable pressure pad 98 are utilized to do this. Anvil 92 has a boss 96, an upper annular surface 108 and a lower annular surface 110. The tab and sheet 2 are clamped as shown in Fig. 11, and the swaging panels moved to form rivet head 104. The clamping serves to restrict the amount of flow in the sheet outwardly and avoids thinning of the rivet during staking. Some minor flow occurs and undersurface 116 of sheet element 2 tends to assume a generally uniform thickness. The join between boss 96 and surface 108 is curved with a radius of between 0À010 to 0À030 inche. Male die 4 has a convex sheet contacting surface 16 having a compound radius, see, Fig. 9 (not shown).
