Title: Improvements in or relating to artificial resinous phosphonic poly-esters
IPC: C08G79/04
Filed: 1948-10-22
Abstract: Thermoplastic resinous materials are produced by condensing a cycloparaffinic phosphonic acid dichloride with a dihydric phenol, the hydroxyl groups of which are separated by at least three carbon atoms.  Condensation may be effected at a temperature rising from 100-190 DEG  C. to 220-300 DEG  C.  Catalysts such as metallic tin may be present.  The cycloparaffin radical may be cyclopentyl or cyclohexyl.  Phenols mentioned are resorcinol; hydroquinone; 4,41 - dihydroxydiphenyl and their chlorinated derivatives.  The products are soluble in chloroform, cyclohexanone, ethylene chloride, mixtures of ethylene chloride with toluene or benzene and certain benzene-alcohol mixtures, and are miscible with nitro-cellulose poly-vinyl chloride and other organic film-forming materials. Pigments and fillers may be incorporated with the products which are mouldable and extrudable. The products may be purified by extraction of unreacted starting materials.  Examples describe polymers from (1) equimolecular proportions of cyclohexyl phosphonic acid dichloride and 4.41-dihydroxydiphenyl; and (2) equimolecular proportions of cyclohexyl phosphonic acid dichloride and hydroquinone.

Title: Parachute
Inventor: STEVINSON HARRY THOMPSON
IPC: B64D17/14
Filed: 1952-11-10
Abstract: 742,587. Parachutes. NATIONAL RESEARCH COUNCIL. Nov. 10, 1953 [Nov. 10, 1952], No. 28321/52. Class'4. A parachute for inanimate objects wherein the canopy is connected through shroud lines to the load so that torque at the load end of the shroud lines is transmitted to the load during at least part of the flight, has the canopy formed of a plurality of gores, at least the majority whereof are separated from the adjacent gores to define slots over the greater portion of the length of the gores, so that air from within the canopy passes tangentially through the slots to rotate the canopy. As shown in Fig. 1, the corners of adjacent gores 11 are interconnected by a stirrup 18 from which shroud lines depend to the load. A tape re-inforcing ring 20 is sewn across the gores about two-thirds of the way towards the crown vent 13, and a second ring 21 is placed about two-fifths of the way from the outer edge B to ring 20. Also, as shown in Fig. 3, a strap 24 inside the canopy is passed through loops 22 formed on one edge A of each gore adjacent the ring 20. The gores may be formed as shown in Fig. 6, where a preformed panel is hemmed at its edges A, B, C, G, and tapes 14 are passed through the hems of sides A, B, C, passing over the crown vent to the diametrically opposite gore, and also form loops at 23, 25 for attachment of the stirrups 18. The fabric is then shirred preferably by 10 per cent on sides A and C, and by 28 per cent on side B. In descent, the inner ring 24 holds edges A inwardly of edges C, so that escaping air rotates the parachute in the direction of the arrows in Fig. 1. If the characteristics of the load and parachute are suitable, the load will be rotated with the parachute, and a stable rotation occurs. If, however, the moment of inertia of the load is high, the load rotates slowly at first, the shroud lines wind up, and the parachute collapses to the squidded condition. Preferably edges C of of the gores are made longer than edges A and the shroud lines are attached to the stirrups 18 so that in the squidded condition, air spills from edges A of the gores, to rotate the canopy in the opposite sense. In any case, the load continues to spin, and unwind the shroud lines, so that the canopy re-inflates. This squidding and inflation may take place a number of times before the load spins fast enough for the shroud lines not to wind up when the parachute recommences rotation after inflation. The parachute may be released with a twist in the shroud lines to commence descent in the squidded condition. When applied as an aircraft air brake, torque is not normally transmitted to the aircraft, but should an aircraft find a second landing approach necessary, the canopy can be quickly collapsed by transmitting the torque to wind up the shroud lines, and later the parachute can be re-inflated.
