The gate 36 is held closed by a pin the arrangement being such that only on the pin being in its correct securing position can a pivotally mounted arming handle 76 of an arming mechanism be retained in its arming position. In the construction shown the apparatus has two missile containers 30, 32 each being secured by a separate gate and securing means, each forward securing means is hinged to the beam 18 through a bracket 40 and comprises a bulkhead 34 which includes a missile guiding tube 50. Each rearward securing means comprises a debris control device. The arming mechanism comprises for each container a plunger actuated by a cam which urges a sheer pin 126 from a transporting position in which it holds the missile in the tube to a firing position in which a reduced portion of the pin is available for shearing and firing them issile. The mechanism also includes for each container a cam operated connector for providing firing current. (Figs. 5, 6, not shown) the movement of the shear pin being effected before movement of the connector for safety reasons. An apparatus similar to that described above may be mounted below the apparatus described to form a four missile launcher (Fig. 3, not shown). A fluid operated elevating device may be attached to the beam of the apparatus (Fig. 4, not shown).

Abstract: 1503765 Applying peat flavours to malted barley A G TAYLOR and G N BATHGATE 9 Nov 1976 [17 Nov 1975] 47225/75 Heading C6E In applying peat smoke to barley malt e.g. for use in the manufacture of Scotch malt whisky, the temperature of the burning peat is maintained at between 325 and 375‹C through controlled pyrolysis. Coarsely ground peat of 5 cms particle size is burnt during passage on a moving chain grate by a stream of hot air and combustion gases at 400‹C, produced by means of a light gas-oil burner, admixed with inert gas. When the temperature of the bed of peat increases above 350‹C further inert gas is introduced into the gaseous input to quench the combustion. Inert gas: steam (preferred), carbon dioxide or nitrogen.

Abstract: 993,932. Knitting machines. KENDALL CO. Dec. 11, 1963 [Dec. 17, 1962; Dec. 3, 1963], No. 48978/63. Heading D1C. For feeding fine yarns, particularly elastomeric yarns, to a knitting machine under controlled tension, the yarn is delivered to a capstan type feed device 10 from a cylindrical yarn package 63 which is unrolled by engagement of a roller 27 therewith which is driven by the same variable-speed drive as the capstan 10. This drive comprises a friction disc 19, on a common shaft 18 of the device 10 and roller 27, which is movable across a constant speed disc 16 driven from the selector drum shaft 12. The yarn is unrolled at 63a from the package 63 and guided at 63b on to helically grooved spindles 28 of the device 10 to be delivered at 63c to the knitting machine. The spindles 28 are mounted in a housing 23 on shaft 18 and inside this housing have gears 29, Fig. 4, engaging a fixed gear 30 on a bracket 20 so that as the housing 23 rotates the spindles 28 also on their own axes. The shaft 18 is mounted in brackets 20, 21 on a shaft 36 which is slidable in bracket 37, 38 by the pull of a cable 41 against a spring 39 to move the disc 19 across disc 16 to vary the speed. The shaft 36 can also be rotated slightly by a cable 81 rotating an eccentric 22 engaging arm 20 so as to lift disc 19 off disc 16 to stop the feed drive. The speed of the feed drive is regulated by a cam (not shown) on a disc 45 actuating a follower 43 on an arm 80 connected to the cable 41. The cam disc 45 is rotated stepby-step by a ratchet pawl 57 oscillated from a link 51 which is actuated by a roller 50 once every revolution of a driving gear 11 of the disc 16. When no change is required in the yarn feed in portions of the knitting a tooth on the ratchet wheel 47 is masked by a bridge 74 so that the wheel is not rotated further until the pawl 57 is moved beyond its normal travel by a wire 56 under control of the selector drum. The roller 27 may be separate from the shaft 18 and driven therefrom by a belt or chain. Alternative forms of the capstan device 10 may be used in which the yarn is passed helically around large and small drums which are coupled by a driving band.

Abstract: 1463653 Adhesive bonded yarn INTERNATIONAL INSTITUTE FOR COTTON 25 Jan 1974 [25 Oct 1972] 49200/72 Headings D1F and D1W A continuous process for the manufacture of yarn comprises subjecting an assembly of fibres e.g. sliver, roving or yarn, which is associated with potentially adhesive material and a controlled amount of solvent or swelling agent for the adhesive material sufficient, but substantially not more than is sufficient to enable subsequent development of the adhesive property to a treatment to develop the adhesive properties of the said material. The potentially adhesive material may be starch, modified starch, or modified cellulose, or may be in the form of fibres e.g. polyvinyl alcohol fibres or water-soluble alginate, cellulose diacetate or cellulose triacetate. The solvent or swelling agent may be water, steam, acetone, formic acid or acetic acid. The activation of the potentially adhesive material may be effected by dielectric heating, radiant heat or heated vapour. To facilitate processing the fibre assembly may be false-twisted preferably pneumatically before and/or simultaneously with and/or after the development of the adhesive property. The assembly of fibres preferably is in the form of a blend of a potentially adhesive fibre and a non-adhesive fibre e.g. polyvinyl alcohol and cotton respectively. In a preferred form of the process, the application of the solvent is followed by a dwell time to allow for penetration of the solvent, and the activation of the adhesive material is also followed by a dwell time to allow for partial hardening of the activated adhesive; the assembly then being dried and wound. It is preferred that the adhesive is removable after the yarn is made-up into a fabric.
