Abstract: 756,037. Coating by electrophoresis; two-part couplings. GENERAL DESCALING CO., Ltd. March 5, 1954 [March 5, 1953], No. 6201/53. Classes 38 (1) and 41. An electrode adapted to be connected to one pole of a D.C. supply and to be drawn through a pipe for applying a coating of bitumen to the interior wall thereof, comprises two or more tubular sections 1, 2, 3 of electrically - conductive material, e.g. copper, assembled end to end with intermediate insulating spacers 4 arranged to permit flexure of the electrode and, in conjunction with a spacer 7, 11 at each end of the electrode, to support the sections 1 ... 3 clear of the wall. Current is supplied to the leading section 1 and to sections 3 by leads 31 connected to a ring 29 in a connector plug P at the leading end of the electrode, and to trailing section 2 by leads 33 from a central flexible rod 5 which is insulated by a sleeve 27 from the plate 29 and has an end cap 26. An ammeter is included in the lead from the rod 5 to the D.C. supply whereby the speed of travel of the electrode through the pipe can be adjusted to give a zero reading on the ammeter, i.e. when the pipe is well coated with bitumen near the trailing section 2. A collar 28 on the sleeve 27 secures the rod 5 at that end, and the far end of the rod 5 is secured and resiliently urged outwardly by a spring 18 in a sleeve 14 in an end cap 12.

Title: Dyeing and printing cellulosic materials with dyes containing haloacylamino groups
Filed: 1958-02-27
Abstract: Solid dyeings and printings are produced on cellulose materials by applying thereto a water-soluble dye of the disazo, anthraquinone or nitro series containing in the molecule at least one group of the formula NHCOCH2CH2-halogen, or a water-soluble dye of the monoazo series containing in the molecule at least two of the above acylamino groups, and fixing the dyeings or printings on the fibre in the presence of acid-binding agents by steaming or heating to an elevated temperature. Advantageously, the dyes have little substantivity so that, after fixation, unreacted dye may easily be removed.  Dyes containing at least two solubilising groups, such as SO3H groups or COOH groups or OH groups ortho to an azo group, are used.  A neutral salt, e.g. sodium chloride or sulphate, is desirably present during dyeing or printing.  A process temperature of at least 100 DEG C. is preferred.  Alkali-metal formates, acetates, bicarbonates, carbonates, phosphates and hydroxides may be used as acid-binding agents, and the corresponding ammonium compounds and basic aliphatic, heterocyclic or aromatic amino compounds may also be used.  Urea is a preferred additive for the printing paste. Where appropriate the dyes may be metallized in substance or on the fibre.  Examples are provided, typical of the dyes used being 1 - amino - 3 - (b  - chloropropionylamino) - benzene-6-sulphonic acid (2 mols) --> 1-amino-8-naphthol-4,6-di-sulphonic acid (1 mol), 1-amino-3-(b -chloropropionylamino)-benzene-6-sulphonic acid --> 2-(b -chloropropionylamino)-5-naphthol-7-sulphonic acid or 1-(41-b -chloropropionylamino - 21 - sulphophenyl - 3 (- methyl - 5 - pyr -) azolone, the product of condensing equimolar proportions of 4,41-diamino-diphenylamine-3,21-disulphonic acid and 2,6-dinitro-1-chlorobenzene-4-carboxylic acid subsequently acylated with b -chloropropionyl chloride, 1-naphthol-3,6-disulphonic acid \sM 4,41-diaminodiphenyl-cyclohexane --> 1-(b -chloropropionylamino)-8-naphthol-3,6-disulphonic acid (alkaline couplings), 1 - amino - 3 - (b  - chloropropionylamino) - benzene-6-sulphonic acid --> resorcinol \sM 2-aminophenol-4-sulphonic acid (copper complex) and <FORM:0886379/IV (c)/1> Brown, red, blue and yellow shades are obtained.
