Abstract: 523,837. Ornamenting; dyes. SOC. OF CHEMICAL INDUSTRY IN BASLE. Jan. 16, 1939, No. 1419. Convention date, Jan. 15, 1938. [Class 93] [Also in Group IV] Aluminium or alloys thereof provided with an oxide coating by electrolysis or by purely chemical action are coloured by means of a water-soluble ester-like or amide-like dyestuff derivative obtained by the process described in Specifications 480,358 or 505,504, [both in Group IV]. The article may be immersed in a solution of the dyestuff, a solution may be applied by painting or spraying, or a paste may be applied, by printing. The colour may be produced in two stages comprising dyeing followed. by regeneration of the dyestuff by saponification or hydrolysis; also, dyeing may take place simultaneously with the production of the oxide coating The following examples are described:-(1) A bluish-grey aluminium sheet is produced by suspending an oxide-coated sheet in an aqueous solution of the product of the action of metasulphobenzoyl chloride on the azo-dye 2-methyl- 4-nitraniline 2:3-hydroxynaphthoic acid otoluidide and subsequently in a mixture of common salt solution, water and ammonia solution. (2) A yellow sheet is produced by using an aqueous solution of the product of the reaction of either meta-sulphobenzoylchloride or 4-chloromethyl-1-benzoyl chloride with pyridine on the tertiary condensation product from cyanuric chloride, 2-aminoanthraquinone and aniline. (3) A brown colour is produced by using an aqueous solution of the product of the action of 3 :5-disulphobenzoylchloride on the diazo dye 2- methoxy-aniline 2:5-dimethyl-1-aminobenzene 3-methyl-4-chlorophenol. (4) A Bordeaux colour is produced by using an aqueous solution of the product of the action of disulphobenzoylchloride on 1:5-dioxy-4:8-di-para-methoxybenzoylaminoanthraquinone. (5) The dye of example (2) is added to an oxalic acid bath used for producing an anodic oxide film on aluminium, and the film is then treated with a solution of ammonia.

Class 89(3) [Also in Group XXIII] In a compressed air actuated nailing apparatus, the driving piston is retained in its retracted position by an inwardly urged slidable cylindrical bolt engaging a recess in the rear end of the piston, the recess being defined on that side facing said rear end by a flat surface which is perpendicular to the piston axis, and the rear end of the ram piston is terminated in a substantially conical surface which forces the bolt outwardly near the end of the return stroke of the piston. To release the piston for a nail driving operation the bolt is moved outwardly by the action of compressed air entering the pressure chamber of the apparatus to disengage the bolt from the recess. In Fig. 3 a spring loaded locking bolt 511 projects into the pressure chamber 501 and engages a shoulder 512 on a stem 507 of a nail driving piston 502. The head 509 of the stem 507 is shaped so that it will force the bolt outwardly at a constant acceleration during the retraction of the piston 502. Two spring loaded locking bolts may be provided on diametrically opposed sides of the upwardly extending stem of the piston, (Fig. 1, not shown). In a further modification, the locking bolt 414, Fig. 2, is in the form of a differential piston with its smaller surface exposed to compressed air on the inlet side of the main valve 431 and its larger surface exposed to the pressure in a chamber 408 leading to the pressure chamber 401 of the nailing piston 402.
