Title: Improvements in or relating to a catalytic process for preparing polymeric oxetanes
IPC: C08G65/18
Filed: 1961-04-05
Abstract: Chelated aluminium compounds of the structure <FORM:0980093/C2/1> in which R is hydrocarbon, Y is carbon or nitrogen, X is carbon, n is 0, 1 or 2, and Z is an oxygen atom capable of forming a co-ordinating bond with the aluminium, are prepared by contacting a trihydrocarbon aluminium, a dihydrocarbon aluminium hydride, or an alkali metal complex thereof, with a chelating agent and optionally with water. The chelating agent may be a diketone, ketoacid, ketoester, ketoaldehyde, hydroxyketone, hydroxyaldehyde, hydroxyester, dialdehyde, alkoxy acid, ketoxime, aldehyde oxime, hydroxamic acid, dioxime or nitro- or nitroso-compound.  The formulae are given of the products of one mole of R3Al or R2AlH with one mole of acetyl acetone, one mole of hydroxyacetone and with one mole of ethoxy acetic acid.  The compounds are used as catalysts in the polymerization of oxetanes (see Division C3).ALSO:Polymeric oxetanes, including certain novel homo- and co-polymers having weight average molecular weights of at least about 50,000, are obtained by contacting the monomers with a catalyst which is a chelated reaction product of a trihydrocarbon aluminium, a dihydrocarbon aluminium hydride, an alkali metal aluminium tetrahydrocarbon or an alkali metal aluminium trihydrocarbon hydride, with a chelating agent and optionally with water, the catalyst having the structure <FORM:0980093/C3/1> in which R is hydrocarbon, Y is carbon or nitrogen, X is carbon, n is 0, 1 or 2, and Z is an oxygen atom capable of forming a coordinating bond with the aluminium.  Many examples of oxetanes are given including compounds containing unsaturated groups, halogens and nitrogen-, oxygen- and sulphur-containing groups. They may be copolymerized with each other and/or with three ring-membered epoxy compounds.  Examples of the latter include alkylene oxides, epihalohydrins and other halogen-substituted epoxides, unsaturated epoxides, glycidyl ethers and esters and others, e.g. butadiene dioxide.  The polymers containing unsaturated groups are elastomers vulcanizable by sulphur. In the catalyst, the hydrocarbon groups of the aluminium compounds may be alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, alkaryl or aralkyl.  The chelating agent may be a diketone, ketoacid, ketoester, ketoaldehyde, hydroxyketone, hydroxyalkehyde, hydroxy ester, dialdehyde, alkoxy acid, ketoxime, aldehyde oxime, hydroxamic acid, dioxime, or nitro- or nitroso-compound. Typical examples describe the polymerization of 3,3-bis-(chloromethyl) oxetane and unsubstituted oxetane, and the copolymerization of oxetane with alkyl glycidyl ether with and without propylene oxide, of 3,3-bis-(chloromethy)oxetene with propylene oxide, and of oxetane with epichlorohydrin, and the vulcanization of some of the copolymers. Typical catalysts are the chelates of triethyl aluminium of tri-isobutyl aluminium with 2,4-pentane-dione, with and without water.

IPC: F42C9/12
Abstract: 125,127. Midgley, A. H., and Vandervell, C. A. June 2, 1916. Addition to 124,774. Projectile fuses.-Consists in a modification of the time-fuse described in the parent Specification, in which a lead or like covered train of fuse composition is employed, the timing being effected by punching the fuse through an aperture in a movable covering-member. According to this invention, the train is composed of two parts, the two ends of one part being connected to the primary igniter and the explosive in the shell respectively, whilst the other part has one end connected to the explosive and its other end either free or connected to the first part of the train. In the construction shown, the two parts of the fuse-train are entirely disconnected, as represented diagrammatically in Fig. 5. One part, which lies mainly above the movable gapped ring e (similar to that described in the parent Specification), has one end c' leading from the igniting-cap k and the other end c<5> communicating with the explosive charge through a hole g<1>. The other part of the train, disposed below the ring e, has one end c<7> leading to the explosive charge, the other end c<6> being free. It the fuse is punched, say, at m, Fig. 5, the normal path along which the fuse burns, and on which the timing depends, is the path c<1>, m, c<7>. The flame divides, however, at the point m, so that an additional path m, c<3>, c<5> is provided, along which the fuse mav continue to burn should the flame in the normal path be accidentally extinguished. The fuse-train may be made in a sirgle piece, of hair-pin form. as described in the parent Specification, in which case the bend is connected by a separate branch to the explosive charge.

Title: Improvements in or relating to shoe heel building machines
IPC: A43D83/00
Filed: 1949-05-17
Abstract: 661,319. Heel-building machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., ELLIOTT, H. E., and FRAMPTON, S. E. May 16, 1950 [May 17, 1949], No. 13050/49. Class 17 (i). A heel-lift positioning device of a heel-building machine has a number of resilient liftengaging members 41 extending heightwise of the heel and spaced around the side and rear faces of a pair of relatively movable blocks 29, in grooves 43 therein. The device in which the lifts are stacked, compressed and nailed may therefore be adjusted to accommodate heels of different shapes, and the lifts do not move appreciably relatively to each other under building pressure from a presser carried by a beam 3, not shown. The blocks 29 are pivoted on pins 27 removably mounted on rearwardly extending arms 25 pivoted on spindles 23 on a front bracket 9. Their inner faces and the strips 41 slope at an angle similar to that of the side and rear faces of the stack of lifts. Screws 37, adjustably mounted on the bracket 9, engage the outer face portion of the blocks 29 under action of spring plungers 35, and are set so that when the blocks are moved towards the lifts, the rubber members 41 which engage the rear rounded faces of the lifts do so before those which engage the sides, so as to cause the lifts to be pressed against a breast gauge 17 adjustable, by screw 21 in block 15 supported on upper surface 7 of post 1, relatively to nail block 18. The blocks 29 may be swung towards one another by movement of a block 67 through toggle levers 65, levers 51, links 47 and arms 25. When bars 5 (not shown) are swung forward by the operator to bring the presser member carried by a beam over the stack of lifts on post 1, the block 67 is moved rearwardly and blocks 29 are moved towards each other to press the stack against gauge 17 and then against the sides and rear face of the stack. The blocks 29 are adjustable relatively to each other according to size of heel by clamping screws 61 in slots 59 and eccentric portions 53 which move the front ends of levers 51. The invention is described in relation to a machine generally similar to that described in Specification 420,293 wherein nails are driven into both the upper and lower ends of the stack.
