Title: Manufacture of new dyestuffs
IPC: C09B11/06
Filed: 1920-10-02
Abstract: New acid dyestuffs, probably aurines of the naphthalene series, are obtained by interaction of a tetrahalogen methane and a -naphthol or a substitution derivative having a free 4-position, especially 1-naphthol-2-carboxylic acid; the reaction is carried out in the presence of a neutralizing agent and preferably with addition of a catalyst such as copper or a copper compound. According to examples, dyestuffs are obtained from a -naphthol, or its 6- or 7-sulphonic acid, and tetrachlormethane by stirring with caustic soda solution and copper powder; from 1-naphthol-2-carboxylic acid and tetrachlormethane by stirring either with aqueous caustic soda and copper powder at 65 DEG  C., or with alcoholic caustic soda at ordinary temperature using a copper stirrer; instead of tetrachlormethane, tetrabrommethane may be used.  The dyestuff from 1-naphthol-2-carboxylic acid forms bright blue metal lakes and dyes wool from an acid bath fast violet-blue shades changed to clear blue by afterchroming.

Title: Improvements in or relating to machines for winding yarn or thread
IPC: B65H54/14
Filed: 1936-10-17
Abstract: 472,570. Winding yarns etc.; spools or cop tubes. SCHARER-NUSSBAUMER & CO. Oct. 17, 1936, Nos. 28256 and 28257. Convention dates, Dec. 28, 1935 and Mav 28, 1936. [Classes 120 (ii) and 120 (iii)] In a machine for winding yarns &c. in which a number of spools or cop tubes are mounted in a carrier which is rotated to bring empty spools successively into the winding position, the end portion of the yarn on the completed spool leaving the winding position passes over the uniformly reciprocated yarn guide before it arrives at the winding position of the empty spool and is engaged by temporarily shifted thread transferrer and directed thereby into a thread catch which rotates with the empty spool ; the thread is thus fixed to the empty spool and torn by the pull between the two spools. As shown the spools 8, 8<1> are mounted on spindles in a plate 1 forming part of a carrier which is moved step by step during the winding as described in Specification 467,301, so as to cause the building of the yarn 15 which is led to the spool 8 by the uniformly reciprocated yarn guide 14 ; before engaging the guide 14 the yarn 9 passes around a thread transferrer or deflecting member 10 pivoted on a pin 11 and normally held by a spring against a stop 13. When the winding on the spool 8 is completed, an arm 1<1> on the plate 1 leaves a rail 5 and the carrier is then returned by a spring to its initial position and rotated by automatic means on its spindle 3 to bring the empty spool 8<1> into the winding position, the yarn being laid in an open helix on the completed cop and the member 10 being moved by the plate 1 to shift the thread from one side of the guide 14 to the other and into the path of the thread catch 19 on the head 7<1> of the spindle carrying the spool 8<1>. The winding on the spool 8<1> then proceeds, the yarn is ruptured between the heads 7, 7<1> of the two spindles and the completed cop is removed from the spindle 6 and replaced by an empty spool ; the return movement of the member 10 with the rotation of the spool 8<1> moves the yarn to the original side of the thread guide. In another arrangement the thread transferrer comprises a pair of curved wire arms fixed in bores in a head on the plate 1. The thread catch 19 may be mounted on the spool and comprises a spring arm secured at one end to the spool or spindle head and clamping the yarn against the spool or head intermediate its ends ; in a modification the thread catch comprises an annulus of springy wire mounted in a groove in the spindle head with one end projecting therefrom and the thread is deflected into the catch when the spool carrier is rotated by one of the pair of curved wire arms extending from the boss on the axis of the carrier.

Connecting uppers to insoles and soles; stiffeners; soles.-In the manufacture of a boot without an insole, the sole b of the boot is cut slightly larger, except at the seat, than the bottom of the last a to be used, and is split at its edge to form two lips c, d extending from the waist, round the toe end, and to the waist at the other side. The sole is tacked to the last, the lip c is turned up and held by tacks e, and the inner lip d is trimmed to the dimensions of the last bottom. The upper f with lining g and toepuff q is placed on the last, and the lip d and edge of the upper are treated with strong rubber adhesive. The upper is now lasted and its edge pressed upon the lip d until the adhesive has set, a wire binder holding it in position round the toe during setting. The heel end of the upper is lasted and tacked. The outer surface of the edge of the upper and the inner surface of the lip c are now roughened, coated with the adhesive, and pressed into contact. The edge of the upper may also be stitched to the lip d or to both its lips by vertical stitching, for which purpose the lip c may be channelled on its outer surface. To reduce thickness at the edge either lip may be reduced, or the slit may be cut at an angle to the plane of the sole. The edge of the lining may come between the lips c, d or stop short of them. Preferably, the heel end of the sole is split completely to form two layers a<1>, a<3> between which a building-up lift a<2> is placed. A shank-stiffener comprising a resilient metal strip s, Fig. 13, is fixed between the layers or, preferably, the strip s is secured to a fibre or like member t which is skived, as shown, and is cut to the size and shape of the inner layer a<3>. In a modification, the member t is of rounded cross-section. A shank may be secured inside the waist and a sock placed over it.
