Title: Improvements in or relating to the Treatment of Wool
Filed: 1967-04-26
Abstract: 1,174,822. Shrinkproofing wool; textile treating apparatus. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. 26 April, 1967 [26 April, 1966], No. 19249/67. Addition to 1,074,731. Headings D1L and D1P. Wool in the form of a continuous sliver is shrink proofed by treating it with an acidified solution containing free chlorine having a pH value of less than 4 and then treating it with a preformed synthetic polymer which is either water-soluble or able to form an aqueous dispersion, e.g. a polyamide-epichlorhydrin resin, polyacrylate or polyethyleneimine. The wool may take up 0.1-1% by weight of chlorine and less than 2% by weight of polymer. In Fig. 2 wool in sliver form is fed continuously at a rate of the order of 300 pound per hour to bowl 1 whereit is scoured to an oil content of about 0.5% in an aqueous solution of a non ionic detergent at 65C, passed through squeeze rollers 7 to bowl 2 where it is rinsed and passed to bowl 3 containing an acidified free-chlorine-containing solution and having a series of two or more pairs of squeeze rollers conveniently spaced about 8-20 inches apart and positioned so that the sliver in progressing through these squeeze rollers is held beneath the surface of the solution. One or more jetting arrangements are situated after all but the last pair of squeeze rollers comprising pipes 10 each having a series of holes or jetting nozzles along its length and arranged to jet solution on to the sliver from above and below. Beneath bowl 3 is a lower bowl 21 of approximately equal volume and an interconnecting large diameter pipe 21a so that if the machine makes an unscheduled stop, the chlorination liquid can be dropped rapidly from the upper to the lower bowl by means of a manually operated lever 22 of air valve 23 to prevent damage to the wool resulting from overlong immersion, the liquid being quickly raised to the upper bowl by means of the same pneumatic system, which by means of valve 23a may also be used to control the liquid level of the upper bowl, when the machine is started again. The wool is then passed through squeeze rollers 12 to bowl 4 containing a combined antichlor and acid-neutralizing solution, preferably of sodium bisulphite and sodium bicarbonate, through squeeze rollers 13 to bowl 5 containing a rinsing solution preferably containing sodium bicarbonate and through squeeze rollers 14 to bowl 6 containing aqueous polymer solution or dispersion and having the same arrangement as the bowl 3. The wool is then passed through squeeze rollers 15 to oven or drier 16 where it may be dried, e.g. at about 105C for about 65 seconds, to a moisture content of 5-25% by weight and partially cured and thence to gill 18 and bin 20. The rate of reaction of the chlorine may be controlled by the temperature of the chlorination liquid by continuously removing a portion of the liquid from bowl 3 by means of pump 24 in line 25, passing it to cooling or heating unit 26 and returning it to bowl 3.

Abstract: A quick-drying sprayable adhesive cement composition comprises 100 parts of a rubbery chloroprene polymer, 30 to 125 parts of a heat-hardening oil-soluble unmodified phenol-aldehyde resin and 15 to 65 parts of an additional tackifier resin of low acid number, the parts being by weight, dissolved in a blend of volatile liquid hydrocarbon non-solvent for the chloroprene polymer and a volatile liquid ester or ketone, the additional tackifier being compatible with the chloroprene polymer and soluble in the blend of volatile liquids.  In the example, a milled base, obtained by milling neoprene with magnesia, zinc oxide and phenyl-a -naphthylamine and cutting the resulting sheet into small pieces, is dispersed in a mixture of petrobenzol and methylethylketone, and a phenol-aldehyde resin and zinc resinate are added with stirring until a uniform solution is obtained. Other solvent blends may be used, e.g. heptane, troluoil, naphtha and cyclohexane may replace petrobenzol, and acetone, methyl isobutyl ketone, ethyl acetate, n-butyl acetate and ethyl lactate may replace methyl ethyl ketone.  The solvent blend may include one or more aliphatic hydrocarbons (including saturated cyclic hydrocarbons), and one or more esters or ketones in preferred proportions of 75 to 40 per cent of the former to 25 to 60 per cent of the latter.  The phenol-aldehyde resins specified are the reaction products of p-tertiary butyl- and amyl-phenols with formalin.  Other additional tackifiers specified are coumarone-indene resins, pentaerythritol ester of wood rosin and terpene resins.  Pigments, antioxidants, fillers, &c., may be added.  The products find particular use in bonding unplasticized natural rubber and plasticized synthetic polymers, such as butadiene-styrene and vinyl acetate-vinyl chloride copolymers, to metal, coated-metal, wood or other rigid supports, as in the bonding of synthetic rubber weatherstripping to lacquered or enamelled portions of car bodies.

Title: Improvements in or relating to apparatus for joining cylindrical members and for applying rotating bands to projectile shells
IPC: B21K21/06
Filed: 1946-07-01
Abstract: 614,068. Making projectiles ; shrinking hoops. STEVENS, A. H. (Mills Industries, Inc.). July 1, 1946, No. 19574. [Classes 83 (ii) and 83 (iv)] An apparatus for joining cylindrical members, such as driving bands to projectiles, comprises a tapered die, separate movable supports for each of said members and means for moving the members through the die to cause them to be bonded together. Driving bands 13 pass downwardly from a magazine 14 through an opening 12 in a block 11, and are in turn pushed into position beneath a tapered die 15 supported in the block 11, by a pusher 21 operated through a link 23 and lever 24 by a spring 39 under the influence of a dashpot 48. The band 13, positioned beneath the die 15 by a stop 50, is supported upon the upper end of a tubular punch 33 connected to a tubular plunger 34. A shell 54 is dropped through the die 15 into the punch 33 and is supported upon the end 53 of a plunger 52 mounted within the tubular plunger 34, in a position such that grooves 56 on the shell are disposed within the band 13. The plungers 34 and 52 are actuated by hydraulic pressure on the pistons 57 and 72 respectively and move together to force the punch 33 into the die 15 the material of the ring 13 being thereby upset into the grooves 56 of the shell 54. The inner plunger 52 continues its stroke until halted by the engagement of an enlargement 86 on the plunger with the end 91 of the plunger 34, to force the shell and applied band completely through the die 15, the projectile then being removed by hand or otherwise. The upward movement of the plunger 34 causes the pusher 21 to move to its rearward position as shown in Fig. 8, being locked in this position by the engagement of a tail 36 of the lever 24 with a shoulder 97 of a locking lever 43. On the retraction of the plungers 34 and 52 prior to the next banding operation, the locking lever 43 is disengaged by reason of its contact with the lower bevelled surface 46 of the punch 33 and the pusher 21 moves to its forward position under the action of the spring 39, placing another band 13 beneath the die 15.
