Title: Improvements in automatic release-links for parachute-borne loads
IPC: B64D17/38
Filed: 1943-02-22
Abstract: 572,833. Fasteners for parachute-borne loads. COOPER, D. W. Feb. 22, 1943, No. 2888. [Class 44] An automatic-release link or fastening for parachute-borne loads which releases when the load touches ground, comprises rotatablyengaged members biased to release position by spring means, but held against release for a predetermined period after leaving the aircraft by holding means under control of a timing device. As shown, the fastening is of bayonet type, comprising a male postern, Fig. 3, engageable with a socket postern, Fig. 2, provided with shackles 43, 60 for attachment to parachute and load. Shackle 43 is mounted on a part 42, with a disc 41 adapted to cover the socket mouth, and with a boss 36 secured to a headed stem 37 on which a sleeve 34 with radial projections 35 is mounted. Sleeve 34 is normally rotatable on the stem, but can be clutched to part 36 so as to be rotatable thereby in the coupling operation by engaging tennons 47 on part 36 in recesses 45 in the sleeve. The socket member comprises a casing 17 with an end 19 backed by a latching plate 31, the end and plate having apertures 20, 32 of the shape shown in Fig. 5 through which the sleeve 34 with its projections 35 can be passed and engaged behind plate 31 by limited rotation. The inner face of plate 31 has radial recesses 33 in which ribs 48 on projections 35 can be seated to prevent release rotation, the ribs being held in the recesses by the tension due to the load. Immediately behind the latching plate is a rotatable sleeve 26 mounted in a fixed guide 22. Sleeve 26 has slots 27 which, in the release position shown, register with the apertures 20, 32, the sleeve being biased to this position by spring 28. Slidably guided in casing 17 is a closed cylinder 11, the inner end of which has upstanding projections 21 registering with the released position of slots 27. Shackle 60 is attached to the outer end of the cylinder, which houses a piston 12 fixed with respect to the casing by pins 15 passing through slots 14 in the cylinder and kept in place by a spring ring 18. When the cylinder is moved inwards or outwards fluid passes from one side of the piston to the other through a valve 56 allowing free flow in one direction and restricted flow in the other. In use, parts 34, 35 are passed through apertures 20, 32 and rotated to register ribs 48 with recesses 33, projection 35 engaging slots 27 and rotating sleeve 26 to put spring 28 under tension. Cylinder 11 is then pushed in to bring projection 21 behind projection 35 to prevent release rotation. When the tension due to the load is applied, it first seats ribs 48 in recesses 33 and then gradually moves the cylinder outwards to withdraw projection 21, thus leaving the fastening free to release when the load tension is removed.

Patent GB-956509-A (GB)
Title: Stretchable fabrics
IPC: D06M15/564
Filed: 1962-01-30
Abstract: Breathable fabrics having a high covering power are produced by treating a normally stretchable fabric with an emulsion comprising a minor proportion by weight of water and a major proportion by weight of a solution of a normally tacky polyurethane resin intermediate reaction product which is a polyester-diisocyanate or polyether-diisocyanate reaction product in an organic solvent for the resin so that each yarn of the fabric becomes coated with the emulsion, curing the coated fabric and then stretching it to break the polymeric webs between the yarns of the fabric. Circular knit, tricot knit and woven fabrics made from cotton, wool, linen, nylon, polyester, polyacrylonitrile, polyurea or polyurethane fibres may be treated, those made from bulked or textured filaments, such as yarn sold under the Registered Trade Mark "Helanca", being preferred. Suitable polyesters used in preparing the polyurethanes are those having molecular weights between 1500 and 5000 formed from glycols, e.g. ethylene glycol, diethylene glycol, triethylene glycol, decamethylene glycol and 1,12-octadecamediol, and dicarboxylic acids, e.g. adipic, succinic, glutaric, pimelic, suberic, azelaic, sebacic, malonic, isophthalic, hexahydroterephthalic and p.phenylene-diacetic acid, and suitable polyethers are those having the formula H(OR)nOH in which R is a hydrocarbon radical and n is an integer sufficiently high to give the product a molecular weight of 500-5000.  The diisocyanate used to prepare the polyurethane may be hexamethylene diisocyanate, a toluene diisocyanate, a naphthalene diisocyanate or p,p1-diphenyl-methane diisocyanate.  The organic solvent used to prepare the emulsion may be 1,1,1-trichloroethane, carbon tetrachloride, chloroform or other halogenated hydrocarbon or an ether.  The fabric may be cured by heating to 50-200 DEG C. and may be stretched by from 5-70% to break the polymeric webs between the yarns of the fabric.

Title: Manufacture of new dioxopiperidines
IPC: C07D211/88
Filed: 1952-02-12
Abstract: The invention comprises 2 : 6-dioxopiperidines of the general formula <FORM:0720198/IV (b)/1> (wherein R1 represents an aliphatic hydrocarbon residue of 1-3 carbon atoms, R2 represents a phenyl residue which is unsubstituted or substituted by a halogen atom, and R3 represents hydrogen or an aliphatic hydrocarbon residue of 1-3 carbon atoms), which may be prepared from 2-R1, R2-disubstituted pentane-1:5-diacids or their functional derivatives (e.g. by reacting the acids or their functional derivatives, e.g. halides, with ammonia or amines, or by intramolecular acylation, by the action of condensing agents, of the monoamides of the acids or their functional derivatives, which may be formed in situ, e.g. from the mono- or di-nitriles or nitrile esters, or by heating the diamides, diammonium salts or mononitrile ammonium salts of the acids).  When the product is unsubstituted in the 1-position, an aliphatic hydrocarbon residue may be subsequently introduced there, e.g. by the action of reactive esters of alcohols or of aliphatic diazo compounds (preferably in the presence of condensing agents capable of converting the dioxopiperidines into metal derivatives, e.g. alkali or alkaline-earth metals or their amides, hydrides, hydrocarbons or alcoholates).  The products are useful as anticonvulsive agents.  In examples: (1) 2-phenyl-2-ethylpentane-1 : 5-diacid 1-mononitrile is heated with glacial acetic acid and concentrated sulphuric acid to produce 3 - phenyl - 3 - ethyl - 2 : 6 - dioxopiperidine; (2) 2-phenyl-2-isopropylpentane-1 : 5-diacid 1-mononitrile similarly yields 3-phenyl-3-isopropyl-2 : 6-dioxopiperidine; (3) the 1-mononitrile in (1) is replaced by the 1-monoamide; (4) the product of (1) is warmed with sodamide in toluene and the product heated with methyl iodide under pressure, producing 1 - methyl - 3 - phenyl - 3 - ethyl-2 : 6-dioxopiperidine; (5) n-propyl bromide similarly gives 1 - n - propyl - 3 - phenyl - 3-ethyl - 2 : 6 - dioxopiperidine; (6) 2 - p - chlorophenyl - 2 - ethylpentane - 1 : 5 - diacid 5-monomethyl ester 1-mononitrile is heated with glacial acetic acid and 85 per cent sulphuric acid to form 3-p-chlorophenyl-3-ethyl-2 : 6-dioxopiperidine; (7) 2-phenyl-2-methylpentane-1 : 5-diacid 5-monomethyl ester 1-mononitrile similarly yields 3-phenyl-3-methyl-2 : 6-dioxopiperidine; (8) the product of (6) is methylated as in (4) except that dioxan is used instead of toluene as solvent.  The aliphatic hydrocarbon residue may also be an unsaturated radical, e.g. allyl.  2 - Phenyl - 2 - ethyl - and - 2 - isopropylpentane - 1 : 5 - diacid 1 - mononitriles are obtainable by condensing a -phenylbutyronitrile or a -phenyl-b -methylbutyronitrile with methyl acrylate and hydrolysing the resulting monomethyl ester mononitriles. 2 - p - Chlorophenyl - 2 - ethyl - and 2 - phenyl-2 - methyl - pentane - 1 : 5 - diacid 5 - monomethyl ester 1-mononitriles are obtainable similarly (but omitting the hydrolysis) from a -(p - chlorophenyl) - butyronitrile and a -phenylpropionitrile respectively.
