Title: New dyestuffs of the stilbene series
Inventor: ANDREW HERBERT FRANCIS
IPC: C07D249/24
Filed: 1958-09-29
Abstract: The invention comprises dyestuffs which, in the form of their free acids, are represented by the formula:-  <FORM:0862225/IV(c)/1> wherein nucleus R may contain substituents and may form part of a naphthalene nucleus, B is chlorine, bromine, nitro, acylamino in which the acyl radical is derived from a carboxylic acid, N : N-dialkylamino or a group of the formula:-  <FORM:0862225/IV(c)/2> A is hydrogen or a triazinylamino group of the above formula, R1 is hydrogen or alkyl of 1 to 4 carbon atoms, Y is chlorine or bromine and Z is chlorine, bromine, alkyl, aryl, alkoxy, aryloxy, thioaryl, thioalkyl, amino or substituted amino provided that the dyestuffs contain at least one triazinylamino group of the above formula.  The dyestuffs are made by treating a triazolylstilbene of the general formula:-  <FORM:0862225/IV(c)/3> wherein P is a hydrogen atom or an -NHR1 group, Q is chlorine, bromine, nitro, acylamino in which the acyl radical is derived from a carboxylic acid, -NHR1, N : N-dialkylamino or the <FORM:0862225/IV(c)/4> group and R and R1 have the meanings given above, provided that the triazolyl-stilbene contains at least one -NHR1 group, with a triazine of the formula:- <FORM:0862225/IV(c)/5> where Y and Z are as stated above.  The dyestuffs colour cotton, viscose rayon, linen, wool and polyamide textiles greenish-yellow shades.  The triazolyl-stilbene derivatives of the above general formula where Q is chlorine, bromine, nitro, acylamino or N : N-dialkylamino are made by diazotizing a stilbene of the formula:-  <FORM:0862225/IV(c)/6> coupling with an ortho coupling amine of the formula:-  <FORM:0862225/IV(c)/7> and treating with a mild oxidizing agent.  The trizolyl-stilbene derivatives where Q is a <FORM:0862225/IV(c)/8> group are made by coupling tetrazotized 4 : 41-diaminostilbene-2 : 21-disulphonic acid with two molecular proportions of the above ortho coupling amine and treating with a mild oxidizing agent.  The triazolyl-stilbene derivatives where Q is -NHR1 are made by coupling a diazotized stilbene of the formula:- <FORM:0862225/IV(c)/9> with the above ortho coupling amine, oxidizing and hydrolysing the amide group.

Filed: 1927-11-21
Abstract: 280,957. Siemens & Halske Akt.- Ges. Nov. 22, 1926, [Convention date]. Two-way repeating systems. - In a system designed to prevent back-coupling, the two speaking paths include filter circuits S1, S2 which admit different frequency bands, and a control circuit associated with each path operates on the arrival of speech currents to cut out the filter circuit of that path, and to disable the return path. As shown in Fig. 2, the control circuit comprises a rectifier g1 and a relay r1, which on energization short-circuits the filter S1 and opens the return path of the amplifier. In another arrangement, Fig. 3, each path comprises a normally inoperative amplifier W1, W2 in parallel with the filter S1, S2 and an amplifier V1, V2. On the arrival of speech currents over the line a1, the control device g1 serves to render operative the amplifier W1, and to disable the amplifier V1, the amplifier V2 of the return path, and also the control device g2 of that path. This is effected by the shifting of the grid potential. The amplifiers W1, W2 may take the form of two amplifiers acting differentially, one of the pair being disabled by the control device. The whole range of transmission frequencies is divided up into two or more bands which are suitably allotted to the filters S1, S2.
