Movement of a first cross-bar disengages a clutch member from a stop member, movement of a second cross-bar in another direction then operating the clutch member to complete a connection. The clutch member 6 individual to a cross point is attached to a lever 5 flexible horizontally. The clutch 6 is normally pressed into a notch 15 in a fixed member 17, but when vertical bar 19 is lifted, fingers 18 rock the related levers 5 counterclockwise against the action of springs 9 to lift clutches 6 into engagement with notches 22 in horizontal cross-bars 20. Movement of the selected bar 20 to left or right, as the case may be, takes along the horizontal spring sets 1 of the selected cross point into engagement with bare wires 4 or 41 respectively of one or another vertical multiple. The spring sets of one horizontal multiple may be cut from a single piece, Fig. 16, the springs being bent as shown in Fig. 17 and placed in grooves in an insulating member 81.

Abstract: The invention comprises the manufacture of azo dyestuffs of the stilbene series by condensation of 4 : 41-dinitrostilbene-2 : 21-disulphonic acid with an aminomonoazo dyestuff of the general formula <FORM:0669706/IV (c)/1> (wherein R1 and R2 each represent an aromatic residue of the benzene or naphthalene series), the dyestuffs so obtainable and the dyeing of leather (especially chrome leather) therewith. The preparation of the dyestuffs may be effected by condensing, advantageously in a dilute (e.g. 2.8 per cent) solution of an alkali hydroxide, preferably at a raised temperature (under reflux or at superatmospheric pressure), 1 mol. of 4 : 41 - dinitrostilbene - 2 : 21 - disulphonic acid with 1 or 2 mols. of an aminoazo dyestuff of the above kind, or with 1 mol. each of two different aminoazo dyestuffs of the above kind, or with 1 mol. of an aminoazo dyestuff of the above kind and 1 mol. of any desired primary aromatic amino compound (e.g. m-nitraniline, p-aminocinnamic acid or dehydrothiotoluidine sulphonic acid), or the molar proportions of the components may be other than whole members.  Suitable aminoazo dyestuffs of the above kind are obtainable by coupling a diazo compound of an amine p  HO3S-R1-NH2 (e.g. aniline o-, m-or p-sulphonic acid, 4-nitroaniline-2-sulphonic acid, 2-methoxy- or 2-nitro-aniline-4-sulphonic acid, 4 - nitro - 41 - aminodiphenylamine - 2 - sulphonic acid, 1-naphthylamine-4- or -5-sulphonic or -3 : 6-, -4 : 6- or -4 : 7-disulphonic acid, 2- naphthylamine-6- or -7-sulphonic or -3 : 6- or -6 : 8-disulphonic acid, 1 : 8-aminonaphthol-3 : 6-disulphonic acid or 4-nitro-1-naphthylamine-5-sulphonic acid) with a diamine H2N-R2-NH2 capable of coupling (e.g. o- or m-phenylenediamine, 4-chloro- or 4-methoxy-1 : 3-diaminobenzene, or 1 : 5- or 1 : 8-diaminonaphthalene).  Examples and a table describe the use of certain of the components specified above, and the dyeing of chrome leather reddish-brown with the condensation product of equimolecular proportions of 4 : 41 - dinitrostilbene - 2 : 21 - disulphonic acid and the dyestuff 1-naphthylamine - 5 - sulphonic acid --> m - phenylenediamine.

Abstract: 510,598. Colour photography. GROVES; W. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 31, 1938, No. 2985. [Class 98 (ii)] A material for colour photography comprises a support, one or more light sensitive layers and a separate light filter layer for use in projection of the colour picture and which is resistant to decolorizations by photographic treatment baths, the filter layer lying behind the light sensitive layer or layers during the exposure. In one example a layer coloured feebly blue with Brilliant Benzo Fast Green is cast on the emulsion layer of a multi-colour grain screen film or plate, or one coloured with Fulling Yellow and Methyl Blue is cast on the emulsion layer of a lenticular screen film, the latter dye being removed in the treatment baths. The layer which is of a neutral grey colour thus acts as an antihalation layer. A material comprising three superimposed emulsion layers each differently sensitized and on one side of the support, has on the other side of the support a red layer which contains a mixture of Supranol Red B and Supranol Red 3B. The tint of this filter is afterwards determined in accordance with its use, by immersion in a bath of thiourea. The two dyestuffs have a different resistance to the bleaching action of the bath and give a range of colour from blue to red. A material with two emulsion layers on one side and one emulsion layer on the other side of the support has a filter layer of Brilliant Cresyl Blue, the tint being determined by acid or alkaline treatment giving the colours blue or yellow respectively.
