Title: Improvements in the fabrication of tubing
IPC: B29C48/90
Filed: 1944-11-23
Abstract: Hot thermoplastic tubing 9 from an extrusion die (not shown) is supported by introducing a fluid, e.g. air, into the tubing and is drawn to circular or polygonal cross-section by being pulled through draw-plates 3, 4, 5 and a final inclined plate 11.  The plate 5 forms the end of a cooling trough 8 and a thin film of coolant is maintained between the tubing and the <PICT:0602321/IV(a)/1> drawing surfaces of the plates.  To ensure this, the opening through the set of plates 3, 4, 5 constitutes the frustrum of a cone and the coolant flows out through openings in split spacing rings 6, 7.  The extrusion die is of larger diameter than the opening in the plate 3, so that the tubing makes contact with the drawing surfaces of the plate.  The tubing may expand between the plates 3 and 11 and the plate 11 shapes the tubing to its final shape.  A circular die may be used for making polygonal tubing by providing the draw-plates with openings of the required section. Suitable thermoplastic materials are cellulose esters and ethers, polyvinyl esters and halides, certain polymeric vinylidene compounds and copolymers thereof with other polymerizable materials, and polyamide resins.  Cellulose acetate butyrate is specifically mentioned.  The coolant is preferably water, but it may be glycerine, hydrocarbon oils or a gas.

Filed: 1944-12-01
Abstract: 583,767. Parachutes. ISACCO, V. Dec. 1, 1944, No. 24017. [Class 4] In parachutes and plane cabin parachutes with rotating sustaining blades, the initial falling is utilised to drive the blades mechanically. Figs. 1 and 2 show a harness yoke 56 universally jointed to a cylindrical carrier I on which is rotatably mounted a circular member 17 carrying pivoted telescopic sustaining blades 12 ; the member 17 is bolted to a top plate 11 which is rotated by means of a driven pulley 22 carrying bevel wheel 23 meshing with a bevel wheel 21 bolted to the plate 11, the pulley 22 being driven, as the parachute begins its fall, by a cord 24, with turns at its lower end wound on the pulley and attached at its upper end to the fuselage F of an aeroplane. A lewis 68 engaging eyes 76 on the pulley bearings serves to support the parachute and is suspended by a wire 70 from a spring pulley 73, the first downward movement of the parachute putting a strain upon the wire 70 sufficient to release the lewis from the eyes 76 and the cord 24 being then tightened to rotate the pulley 22 and becoming free of the pulley when all the cord turns are'unwound. The blades 12, freely 'pivoted on horizontal axles carried on eyes 31 of spigots' 19 mounted in ball bearings on'the member 17, swing outwardly and are extended by the rotation imparted to the member 17, tongues 38 on the blade mountings engaging in catches 39 to lock 'the blades in the outward position; the horizontal axles for pivoting the blades may be inclined at 90 degrees to the blades as shown or at a greater angle. The sections of the telescoping blades have internal engaging shoulders to limit the outward movements of the parts and a cord 81 connected between the innermost section and a spring pulley 80 serves to contract the blades as rotation stops. Fig. 8 is a cross-section of one of the blade sections. More than two blades may be used. Fig. 13 shows a cabin 100 with parachute apparatus in a fuselage F1. A set of telescoping tubular elements 60, Fig.. 1, shaped to prevent rotation therein of the lewis 68 serves as a torque reaction absorber. Fig. 6 shows the spring pulley 80 carried on an elastic band 85 stretched between stubs 86; rotation of the pulley 80 by unwinding the cord 81 acts by a cross-pin 89 to wind or tension the band 85 in readiness for retraction of the blades.
