Title: Manufacture of new azo-dyestuffs
IPC: C09B45/14
Filed: 1946-01-17
Abstract: Azo dyestuffs are manufactured by coupling a 1-naphthol containing as a substituent in the 4-position an alkyl radical of more than one carbon atom or a cycloalkyl radial, with an o-hydroxylated and sulphonated diazo compound.  The products may be used for dyeing by the after-chroming process or by the process in which the chroming agent is present in the dye bath from the outset, and they may also be treated in substance with agents yielding metal, e.g. compounds of copper, nickel, cobalt or especially chromium, or mixtures of such compounds, producing metalliferous dyestuffs suitable for dyeing animal fibres or other fibres having an affinity for acid dyestuffs. Examples describe the preparation of the following dyestuffs: (1) 1-hydroxy-2-amino-4-nitro- or -4-chloro-benzene-6-sulphonic acid --> 4-n-butyl-1-hydroxynaphthalene; (2) 1-amino-2-naphthol --> 4-ethyl- or 4-n-butyl-1-hydroxynaphthalene; and the dyeing of wool with the products of (1) with simultaneous or subsequent chroming. Lists of additional components are given.  The Specification as open to inspection under Sect. 91 comprises also the use of diazo compounds containing, in o-position to the diazo group, a substituent convertible into or exchangeable for a hydroxy group, and the metallization of the resulting dyestuffs under such conditions that this substituent is hydrolysed to or replaced by a hydroxy group. Reference is also made to the replacement of the coupling component in example (1) by 4-ethyl-1-hydroxynaphthalene.  This subject-matter does not appear in the Specification as accepted.

Abstract: 978, 556. Photographic printing and developing apparatus. HALL HARDING Ltd., and W. R. H. MOON. April 19, 1961 [Jan. 19, 1960], No. 1959/60. Heading G2A. A photographic printing and developing apparatus comprises a printing cylinder mounted for oscillatory rotatory movement about its axis, driving ing means for the cylinder including a clutch which is disengaged between completion of an intake stroke and commencement of an ejection stroke so that the cylinder is stationary for a timed period during which a photocopying exposure can be made, and settable control means for automatically disengaging the clutch at the completion of a predetermined number of ejection strokes of the cylinder. In the embodiment shown the drum is driven by a chain from a sprocket 33 (Fig. 5) on a shaft 34 which is oscillated by means of a rack 43 which engages a pinion 41 on the shaft 31. The rack 43 is driven through a tank 48 and a clutch, comprising parts 47, 48, and a motor driven pinion 51 rotatably mounted on shaft 34 and connected by a chain 53 to part 47. The parts 47, 48 are clutched by a spring urged pin 55 which can be disengaged by one of two pivotted knives 65, 66 engaging a slot 69 in the pin. The setting control means, Fig. 7, comprises a counting ratchet 93 and a setting wheel 112 which are operatively connected by abutting pins 106, 107 so that when wheel 112 is rotated by a predetermined amount ratchet 93 is rotated by this amount also and is held by a holder pawl 101 until it is driven step by step by a driving pawl 102 which is connected indirectly by a Bowden cable' 105 and levers to a cam riding on the surface of wheel 48. When the apparatus is operated a yoke 125 is rotated so that a Bowden cable connecting it to the knife 65 removes said knife from clutch pin 55 and is locked in position by a lever 123. The drum is rotated until the knife 66 disengages the clutch and simultaneously a projection on the periphery of wheel 148 closes a microswitch on a timed circuit which controls the exposure and after a predetermined time operates a solenoid which disconnects the knife and pin 55 so that the drum can continue to rotate. The projection on the wheel then operates through the cam levers and cable 105 so that the pawl 102 moves the ratchet 93 on by one step. The above steps are repeated until the pin 107 on ratchet 93 pivots lever 119 which releases the cable 73 and hence the knife 65 which disconnects the clutch 47, 48 by engaging the pin 55.
