Title: Process for the preparation of polyether-urethane-urea copolymers useful in the prodution of elastic fibres and films
IPC: C08G18/72
Filed: 1965-11-09
Abstract: Segmented substantially linear polyether-urethane-urea copolymers are prepared by (a) heating a difunctional hydroxyl terminated polyether with a molar insufficiency of an aromatic diisocyanate to produce a hydroxyl-terminated polyether-urethane, (b) heating the hydroxyl terminated polyether urethane with at least one mole of an aliphatic or cycloaliphatic diisocyante per equivalent of hydroxyl groups in the hydroxyl terminated polyether-urethane to produce an isocyanate terminated intermediate and (c) mixing the isocyanate-terminated intermediate with p-menthane-1,8-diamine. The polyethers preferably have a M.W. of 700 to 5,000 and those preferred are poly(oxytetramethylene) glycol and copolymers of propylene oxide with tetrahydrofuran. Suitable aromatic diisocyanates are 4,41-methylene-bis(phenylisocyanate), 4,41-methylene-bis(3-methylphenylisocyanate), a mixture of 2,4- and 2,6-toluene diisocyanates and m-phenylene diisocyanate whilst suitable aliphatic diisocyanates are tetramethylene diisocyanate, hexamethylene diisocyanate and more preferably cycloaliphatic diisocyanates such as 4,41-methylene bis(cyclohexylisocyanate), cyclohexane-1,4-diisocyanate and 1,4-cyclohexane-bis(methyl isocyanate). The second stage (b) may be carried out in the presence of an organotin catalyst such as dibutylin dilaurate or stannous octoate whilst the chain extension step (c) preferably takes place in an inert organic solvent such as N,N-dimethylformamide.

Abstract: 1,137,175. Embossing; ornamenting. EDWARD WEBSTER Ltd. 24 April, 1967 [25 Oct., 1966], No. 47809/66. Headings B6G and B6J. The curved surface of a thermoplastic article is simultaneously embossed and coated with decorative material, e.g. gold or silver, in the embossed areas by bringing the curved surface of the article into rolling engagement with a heated embossing die through an interposed sheet or strip of paper or other flexible carrier coated on the side next to the article with a transferable layer of the decorative material. The articles may be supported on rotatable mandrels 18 mounted on a disc 14 rotatable to bring each successive article on its mandrel into rolling engagement with a heated arcuate die 19 adjustable towards and away from the mandrel by micrometer screw 28. Flexible carrier 36 bearing a coating of decorative material is supplied from a spool held by spring clip 43, around spaced pins 45, over brake roller 46 and up to driven scrap winding reel 47. The movement of carrier 36 is momentarily arrested while a cover is in engagement with the die. Probe 53 stops the machine if a mandrel against which it presses does not carry an article. The decorated articles are removed from mandrels 18 by rotating, waisted, rubber covered, ejector roller 54.

Abstract: 1462520 Foam plastics BAYER AG 13 Nov 1974 [13 Nov 1973] 49096/74 Heading C3R Foam plastics based on polyisocyanates, e.g. polyurethane foams are prepared in a closed mould using as an internal mould release agent a reaction product of a mono- and/or polyisocyanate and a polysiloxane of the formula wherein A represents a monovalent group which contains at least one active hydrogen atom, R represents a methyl and/or phenyl radical and/or is the same as A and n is from 3 to 300. Most preferably the polysiloxanes are those which contain 1 to 6 or cycloalkyl groups and/or 1 to 6 -CH 2 OH groups.

Title: Improvements in or relating to apparatus for cold pressure welding
Inventor: ROZMUS WALTER J
IPC: B23K20/02
Filed: 1969-10-08
Abstract: 1,261,566. Welding by pressure; shearing. KELSEY-HAYES CO. 8 Oct., 1969 [11 Oct., 1968; 19 June, 1969], No. 49398/69. Headings B3R and B3W.  Apparatus for multiple upset butt welding of fine wires (e.g. 0À0025 to 0À005 inchs diameter) comprises a set of four dies arranged in pairs 22, 23 and 24, 25, the dies of each pair having at least first and second grooves (and, as shown, third grooves also) which when the dies of a pair are abutting define wire receiving cavities, 28, 29, 31, Fig. 9. In an initial position the dies are spaced laterally from each other by an extra distance sufficient to allow wires 211, 212 to be placed between the dies so as to extend between respective wire locating and holding means e.g. 223, 215, 218, 224 which lightly tension the wires and align them with the wire grooves in the dies. One pair of dies 24, 25 is then held in a lowered position relative to the other pair by means of a handle 327 so that the wires 211, 212 are aligned with the upper and middle wire grooves in the pair of dies 24, 25 and with the middle and lower grooves in the other pair. Next, movement of an operating handle 139 causes the dies of each pair to move laterally towards each other to an abutting position in which the wires are located in the cavities (being gripped in the middle cavities). Release of the handle 327 and operation of a cut-off lever 85 causes the die pair 24, 25 to be raised to its normal position thereby shearing the wires 211, 212 to provide two opposed cleanly sheared wire ends in the middle cavities. The scrap sheared ends may be pulled out of the other respective cavities as these are larger and do not grip the wires. Continued operation of the handle causes the dies to move outwardly to release the wires, then to return to a longitudinally retracted position, then to move inwardly to regrip the wires and then forwardly to cause upsetting of the projecting wire ends which thereby become partly welded. At this stage separate wire holding members bear on the wire so that as the dies again move outwardly to release the wire and then retract the partly formed weld is prevented from being torn apart. Further cycles of movement of the dies i.e. lateral movement to grip the wires, forward movement to the welding, wire-upsetting position, lateral releasing movement and retraction are carried out by continued use of the operating handle 139 to complete the multiple upset weld. Small relief areas 341, 342, Fig. 7, in the dies provide for the formation of weld upset during the welding process.

The shell may alternatively be placed in the mould halves or be formed by flame spraying and is preferably coated with a 10-30% (by weight) solution of phenol in an alkanol. Pressing is carried out at 140-200‹ C.

A counter having zero-setting heart-shaped cams on the digit rollers, which are mounted on a shaft together with tens transfer means and pinions, and having tens indexing wheels on a second shaft to coact with the pinions and tens transfer means, includes a zero-setting shaft having arms to engage each heart cam, and each roller is coupled to the corresponding pinion during counting but uncoupled during zero setting. In one embodiment, Fig. 4, the shaft 2 carrying the rollers 6, which are free to rotate but are axially fixed, is shown in the counting position. For each roller, coupling 8 rotates with the roller and is urged by spring 9 against stop 15 and the arms Sa engage in a pair of ten holes in pinion 7.
