Title: Improvements in or relating to dyeing textiles
Filed: 1936-06-04
Abstract: Azo dyes, forming upon the material.--Textiles are dyed by developing the dye on the fibre of the material which has been impregnated with the second component of an azo dye, by treating it in the presence of alkali with derivatives of azoxycarboxylic acids of the type <FORM:0477689/IV/1> of the type <FORM:0477689/IV/2> where R is a closed ring radicle, such as the benzene, naphthalene, anthracene, diphenyl, dinaphthyl, phenanthrene, fluorene, acenaphthene, chrysene, benzanthrene, dibenzanthrene or pyrene radicle, or a five or six membered heterocyclic radicle with one or more nitrogen, sulphur or oxygen atoms, with or without phenyl substituents, such as the radicle of furane, pyrrole, thiophene, pyridine, quinoline, isoquinoline, carbazole, benzthiazole, acridine, thionaphthene, oxazine, thiazine or diazine, which radicles may contain one or more o-, m- or p-substituents such as the radicles of hydrocarbons of the group CnH2n or CnH2n\sW2, alcohols, aldehydes, ketones, acids, amides, amines, nitro compounds, halogen compounds or sulpho derivatives, or may contain alicyclic groups, or phenyl groups substituted by halogen, NH2, NHX, NX1X2, OH, OX, NO2, SO3H, CO, COOH, CONH2, CONHX, CONXX1 (where X, X1, and X2 have the same significance as R), urea groups or o- or p-quinonoid groups. Suitable derivatives of the said acids are their esters and primary, secondary or tertiary amides, containing respectively the groups --COOR1, --CONH2, --CONHR1, or --CONR1R2, where R1 and R2 are aliphatic, aromatic or heterocyclic groups which may contain substituents which render the compound watersoluble.  In a modification of the process, the material is first impregnated with the azoxycarboxylic acid derivative and the dye is developed on the fibre by treatment in alkaline medium with the second component. In examples: (1) cotton is saturated with the sodium salt of 2 : 3 - hydroxynaphthoic anilide and developed with phenylazoxycarboxylic acid amide, with the addition of caustic alkali or carbonate; (2) cotton is saturated with b -naphthol and developed with b -naphthylazoxycarboxylic acid amide and sodium carbonate; (3) cotton is saturated with 2 : 3-hydroxynaphthoic o-toluidide and developed with the sodium salt of p-nitrophenylazoxycarboxylic acid p<1>-sulphophenylamide; (4) wool or cotton is saturated with b -anthraquinonylazoxycarboxylic acid ethyl ester and developed in alkaline solution with 2 : 3-hydroxynaphthoic p-anisidide; (5) cotton is saturated with 2 : 3-hydroxynaphthoic p-nitranilide and developed in alkaline solution with diphenyl-4 : 4<1>-bisazoxycarboxylic acid amide; (6) cotton is saturated with 2 : 3-hydroxynaphthoic acid a -naphthylamide and developed with 6-ethoxybenzthiazole-2-azoxycarboxylic acid amide.  Azoxycarboxylic acid derivatives.--The azoxycarboxylic acid derivatives employed in examples (2) to (6) are obtained by oxidizing the corresponding azo derivatives with hydrogen peroxide in a suitable solvent.

Abstract: 923,730. Valves. M. H. GROVE. May 6, 1960 [July 31, 1959], No. 16177/60. Class 135. A valve comprises a body with aligned flow passages 11 surrounded by working surfaces 57 for a gate 12 carrying upstream and downstream seals, each seal including a ring 59 to make contact with the associated working surface, annular mounting means 61, 62 for each ring movably carried by the gate, and means 73 forming a seal between the mounting means and the gate in an annular region encompassing a greater area than the ring 59. The means 61, 62 are loosely mounted in a recess 63 so that when the gate 12 is urged away on its upstream side from one of the working surfaces the upstream fluid pressure acts over the larger area encompassed by the means 73 to urge the ring 59 into contact with its working surface. A spring Belleville washer may be mounted behind the means 61, 62 or the means 61 may be made in the form of such a washer. The rings 59 and 73 may be resilient 0-rings of synthetic rubber or of an elastomer, such as nylon, the ring 59 being accommodated between surfaces 67 and 68 having a greater radial spacing than its normal diameter. On the downstream side of the gate a slight clearance is maintained from the working surface by the mounting means engaging the bottom of its recess. The surfaces 57 may be integral with the body or be formed by liners 36 of stainless steel, bronze or the like located by members 40 and clamped together with retainers 26 for resilient 0-ring seals 29 between parts 13 and 14. These parts may be torch-cut from rolled steel and be ground or machined before being clamped together by bolts 31. Reinforcing ribs 24 and flanges 21 are welded to the parts 13. To ensure that the differential pressure is maintained on the upstream seal, the interior of the body is vented to a low-pressure passage. Specification 662,448 is referred to.
