Abstract: 1,065,480. Hose couplings; flexible hoses. SUPERFLEXIT Ltd. Oct. 28, 1965 [Feb. 26, 1965], No. 42170/66. Divided out of 1,059,714. Headings F2G and F2P. The material of a hose 2 of polytetrafluoroethylene, nylon, polypropylene, polyvinyl chloride or polythene is forced into the grooves 4 of a nipple 1 by forcing axially into the hose a liner 5, and the braided or plaited wire hose reinforcement 11 is gripped between the nipple and a ferrule 12. The latter is forced axially over the nipple and secured thereto by swaging the end of the ferrule into a groove 18, and is also peened over the end of the liner as indicated at 10. To prevent rotation of and to hold the ferrule in position the nipple is formed with straight knurling at 19. In modifications, (a) the nipple has an annular groove into which the braid 11 is forced by crimping the ferrule inwardly, the liner and nipple being secured together by an epoxy resin inserted in a groove in the nipple, and (b) the nipple and liner are in screwed engagement, the screw-threads being smeared with an epoxy resin.

Title: Process for the production of unsaturated esters
Inventor: LERER MOISE
IPC: C08G63/66
Filed: 1961-11-30
Abstract: Unsaturated esters are made by reacting (a) the "heavy residues" formed as by-products in the production of alkyl metadioxanes by the condensation of formaldehyde with monoolefins (see Specifications 825,034 and 884,038) or the hydrolysis products of such "heavy residues" with (b) an olefinic acid or a functional derivative thereof (e.g. an anhydride, acid chloride, ester, amide or imide). The acid may be oleic, linoleic, ricinoleic, maleic or fumaric acid or it may be colophony.  The reaction mixture may also include an olefinic alcohol or ester (e.g.an oil such as castor, linseed, tung or dehydrated castor oil).  The esters may be polymerized or copolymerized with other copolymerizable monomers (e.g. styrene, allyl terephthalate or mono-allyl monoethyleneglycol carbonate).  In examples, resinous materials which are soluble in dioxane to yield varnishes, are made by reacting maleic anhydride with (1)-(3), (6) and (7) "heavy residues"; (4) "heavy residues" and castor oil; (5) hydrolysed "heavy residues".  In further examples (7), (11) and (12) wood fibres or glass fibres are impregnated with a composition containing the resin of Example 1 or 5, styrene, cobalt octoate or cobalt octanoate and methylisobutyl ketone peroxide; (9) a varnish comprises the resin of Example 5, dioxane, polychlordiphenyl, cobalt octanoate and a small amount of toluene containing silicones and paraffin wax; (10) a paint comprises the resin of Example 7, polychlorodiphenyl, cobalt octanoate, diethyleneglycol monoethyl ether, yellow ochre and a small amount of toluene containing silicones and paraffin wax.ALSO:Unsaturated esters are made by reacting (a) the "heavy residues" formed as by-products in the production of alkyl metadioxanes by the condensation of formaldehyde with mono-olefins (see Specifications 825,034 and 884,038) or the hydrolysis products of such "heavy residues" with (b) an olefinic acid or a functional derivative thereof (e.g. an anhydride, acid chloride, ester, amide or imide).
