Title: Process for the manufacture of azodyestuffs
IPC: C09B35/374
Filed: 1937-06-24
Abstract: Azo dyestuffs are manufactured by diazotizing the disazo dyestuffs, obtained by tetrazotizing monoaminobenzoylated diamines of the benzene series and coupling first with an o-hydroxycarboxylic acid of the benzene series and secondly with an aminonaphthol mono- or disulphonic acid, and coupling the resulting diazo compounds with m-diamino-, m-aminohydroxy- or m-dihydroxy-compounds of the benzene series or the monoazo derivatives thereof.  The products dye cotton reddish to deep blackish-brown shades of good neutral and alkaline dischargeability.  The dyes may be after-treated on the fibre, e.g. with formaldehyde if one coupling component is a free diamine, or with diazo compounds such as those from m- or p-nitraniline or 1-amino-2-methoxy-4-nitrobenzene.  Examples describe the production of the following dyestuffs: (1) a mixture of salicylic and o-cresotinic acid \sM p - aminobenzoyl - p - phenylenediamine --> 2 : 8 : 6 - acid --> m - phenylenediamine; the product dyes cotton deep brown shades which may be after-treated with formaldehyde; the m-phenylenediamine may be replaced by the sodium salt of the dyestuff sulphanilic acid --> m-phenylenediamine (deep brown shades dischargeable by alkaline or neutral agents), or by the chrysoidine from 1-naphthylamine-4-sulphonic acid and m-phenylenediamine (bluish-brown) or by 1 : 3-phenylenediamine-4-sulphonic acid, and the 2 : 8 : 6-acid by 2 : 5 : 7- or 2 : 8 : 3 : 6-acids; the dyeings may be developed with diazotized p-nitraniline to deep yellowish-brown shades; (2) salicylic acid \sM p-aminobenzoyl-p-phenylenediamine --> 2 : 8 : 6-acid --> resorcinol (reddish-brown shades dischargeable by neutral and alkaline agents and becoming more reddish on treatment with formaldehyde), or the dyestuff metanilic acid --> resorcinol (more bluish-red shades which may be developed with diazotized p-nitraniline to brown shades), or m-aminophenol.

Title: Improvements in or relating to circular knitting machines
IPC: D04B9/06
Filed: 1924-07-26
Abstract: 219,704. Wildman Manufacturing Co., (Assignees of Krieble, C. C.). July 26, 1923, [Convention date]. Circular machines. - Yarn feeding, changing, cutting and clamping means, shown as applied to a rib machine, comprise yarn fingers 8 - - 11 pivoted at 12 and depressed against springs 30 to feeding position by cams 13 on vertical rock shafts 14 held between a bracket 15 mounted on the rotary cam-box 3, and a plate 16 supported thereon. Each shaft 14 carries an arm 20 and can be moved against a spring 18 by contact with a vertically-movable cam 19, the arms 20 and cams 13 being staggered as shown in Fig. 4. Any cam 13 can thus be turned so that its edge working against the shoulder 21 of the corresponding yarn finger brings that finger into feeding position where it is retained by a detent 22 the tooth 22a of which passes below projection 8<a> on the yarn finger. The onward movement of the yarn finger which has been feeding brings a projection 22d on the corresponding detent 22 into the plane of a cam 19<x> which is advanced horizontally into engaging position by an incline 23 on the vertically-movable post 24 which supports the cam 19. The previously-acting yarn finger is thus placed out of action, the arrangement being such that the new yarn finger is first placed in action. Co-operating with the yarn fingers is a feed wheel 32 rotated on its axis in the bracket 15 bv means of a lower wheel geared to the needles. The feed wheel is provided with ratchet-like teeth which are notched so that the upper ends overhang as shown in Fig. 2. The notches form a channel for guiding the yarn to the needles. The free yarn ends pass under a spring clamping plate 36 which lies at an angle to and with one edge in contact with a fixed plate 38 situated in a depression in the upper side of the wheel 32. Fig. 3 shows at a the course of the new yarn after the finger 8 has been lowered and before the yarn has been presented to the needles by the wheel 32. The yarn having been taken by the needles is pulled out of the clamp and runs in the channel formed by the peripheral notches of the wheel 32. The yarn taken out of action is lifted so as to be caught between two of the wheel teeth which pass it under a guard plate 37 and under the clamp 36. Continued rotation of the wheel brings the part of the yarn between the clamp and the fabric to a guide finger 40 over which it rides and is directed to a cutting edge formed integral with the part 40, the upper edge of the tooth which engages the yarn forming the movable shearing edge and the part 40 being held against the wheel by a spring plunger 41.
