Patent GB-404613-A (GB)
Title: The manufacture of azo-dyestuffs
IPC: C09B56/04
Filed: 1932-06-11
Abstract: Azo dyes are made by linking one molecular proportion of an azo dyestuff derived from 4 : 4<1>-nitroaminostilbene- (or dibenzyl-)-2 : 2<1>-disulphonic acid with a different aromatic radicle (which may contain further azo groups) by means of an azo- or azoxy-group.  The linking is effected by condensing the nitro group with an amine or by reducing the nitro group, diazotising and coupling.  The dyestuffs which have affinity for cotton and leather may be subjected to the usual after-treatment processes in substance or on the fibre, e.g. with copper compounds.  Metal compounds may be formed in the final coupling operation.  In examples the following dyes are described: (1)--(4) the ethylated or methylated monoazo dyestuff 4 - nitro - 4<1> - aminostilbene - 2 : 2<1> - disulpho acid --> phenol is condensed with p-phenetidine in caustic soda (yellow on cotton), dehydrothiotoluidine sulphonic acid (orange), metanilic acid --> 1-methyl-3-amino-4-methoxybenzene, or sulphanilic acid --> 1-naphthylamine; the products may be oxidised, e.g. with hypochlorite, (5) the methylated and reduced dyestuff 4 : 4<1> - nitroaminostilbene - 2 : 2<1> - disulpho acid --> phenol --> K acid <FORM:0404613/IV/1> 4-nitro-2-aminophenol; the second coupling is made in presence of pyridine hydrochloride; the last component may be 5-nitro-2-aminobenzoic acid, 4-nitro- or 4-chlor-2-aminoanisole picramic acid or 6-chlor-4-nitroaminophenol; the phenol may be replaced by a yellow component, e.g. salicylic acid, acetoacetic anilide or by other components of the benzene and naphthalene series, (6) the methylated and reduced dyestuff 4 : 4<1> - nitroaminostilbene - 2 : 2<1> - disulpho acid --> phenol (2 mols.) \sQ K acid or resorcinol, (7)--(8) the methylated and reduced dyestuff of (5) <FORM:0404613/IV/2> J-acid <FORM:0404613/IV/3> o-anisidine or 4-nitro-2 - aminophenol or the same dyestuff <FORM:0404613/IV/4> J acid <FORM:0404613/IV/5> aniline; the former may be treated with copper compounds and the 4-nitro - 2 - amino - phenol may be replaced by 4 - nitro - 2 - amino - anisole, 6 - chlor - 4-nitro-2 - aminophenol or 4 : 6 - dinitro - 2 - aminophenol, (9) copper compound of the dyestuff 4 - chlor - 2 - aminophenol - 6 - sulphonic acid --> resorcinol \sM the methylated and reduced monoazo dyestuff of (5); the first component may be 2-chloraniline-4-sulphonic acid, (10) the dyestuff 4 : 4<1>-nitroaminostilbene-2 : 2<1>-disulpho acid --> a -naphthylamine --> salicylic acid is condensed with dehydrothiotoluidine-sulphonic acid or 4-aminoazobenzene-4<1>-sulpho acid in caustic soda solution.

Patent GB-945330-A (GB)
Title: Halogen-containing hydroquinolines
Inventor: BROWN JOSEPH PATRICK
IPC: C07D215/58
Filed: 1961-05-08
Abstract: Halogenated products are obtained by reacting a 1,2-dihydroquinoline having an aliphatic substituent in the 4-position with a halogenating agent.  The invention also comprises 4-halogeno-aliphatic-2,2-dialiphatic-1,2-dihydroquinolines and their salts.  Suitable halogenating agents are the free halogens, sulphuryl halides, and N-halo compounds such as N-bromosuccinimide; preferably the halogen introduced is chlorine or bromine. Preferred starting materials are those of the formula: <FORM:0945330/C2/1> where R1 is hydrogen or a hydrocarbon or acyl group (especially aliphatic carboxylic acid of up to 4 carbon atoms or aromatic sulphonic acyl), R2 and R3 are aliphatic hydrocarbon groups, R4 is an aliphatic group, R5 is halogen, alkyl, aryl, alkoxy or other inert group, and n is 0-4.  The first halogen atom introduced normally enters the a -position of the 4-substituent; the second and third halogen atoms, if introduced, normally enter the dihydroquinoline nucleus; further halogenation can saturate the double bonds of the dihydroquinoline nucleus or can produce N-halogenation: up to 10 halogen atoms can be introduced.  An N-carboxylic acyl group is generally removed during the halogenation. The products of the invention are mycobacteriostats (see Division A5).  The Provisional Specification refers generally to the halogenation of 1,2-dihydroquinolines, including -isoquinolines.ALSO:Mycobacteriostatic compositions comprise an inert diluent and a product obtained by halogenating a 1,2-dihydroquinoline having an aliphatic substituent in the 4-position, especially a 4-halogenoaliphatic-2,2-dialiphatic-1,2-dihydroquinoline, particularly those of <FORM:0945330/A5-A6/1> wherein R1 is hydrogen, alkyl or aromatic acyl, R2 and R3 are alkyl, n is 0 or 1 to 4, R5 is alkoxy, alkyl or halogen, R6 is halogeno aliphatic and y is hydrogen or halogen, or a salt thereof (see Division C2).  The compositions may comprise the active ingredient in an aqueous medium stabilized by a surface-active agent, or in an organic solvent, and the solution can then be emulsified in an aqueous medium; suitable solvents are toluene, cyclohexane, petroleum ether, chloroform, chlorobenzene, and vegetable and animal oils; the emulsions may be lotions, pastes, creams or ointments.  Solid compositions may be prepared using an inert solid such as talc.  Specified salts are the oxalates, sulphates, hydrochloride, hydrobromides and quaternary ammonium halides.  The active ingredients are also added to soaps, waxes and synthetic plastics.  Other forms specified are suspensions and solutions.  Various surface-active agents are named.

Abstract: 183,678. Igranic Electric Co., Ltd., (Cutler-Hammer Manufactitring Co.). June 23, 1921. Switches, quick-action; pneumatic actuation.- A pressure-controlled switch is provided with snap-action operating-means comprising an oscillatory cam 13 with inclined faces meeting in an abrupt crest, a spring-controlled element 22 held in engagement with the cam, and means for moving the element in reverse directions across the cam, the arrangement being such that the face of the cam on one side of the crest affords greater opposition to the movement of the element towards the crest than does the face of the cam on the other side of the crest. As shown, the element 22 comprises a roller carried by a lever 21 pivoted at the free end of a lever 16, the other end of which is pivoted at 17 to the casing 10. The cam 13 is secured to the shaft 12 carrying the movable contacts 8. An opening 28 at the bottom of the casing 10 is closed by a diaphragm 29 which is clamped between a header 30 and the casing, resilient gaskets 40, 41 being provided to reduce strains on the diaphragm. The fluid under pressure for controlling the switch is admitted to the header through an opening 31, and the pressure is transmitted to the lever 16 through a member 32 pivoted to the lever at 39. The member 32 rests on a pin 38 carried by the diaphragm, and is recessed at 36 to receive one end of a compression spring 34, the other end of which is retained by an adjusting-nut 35 screwed into the casing 10. The end 18 of the lever 16 is forked for the passage of the spring. When the pressure beneath the diaphragm rises, the spring 34 is compressed and bowed, aud the free end of the lever 16 rises and carries the roller 22 towards the crest of the cam, at the same time straining a spring 23. When the roller passes the crest of the cam, the movable contact-member is thrown into the off position and held there by the engagement of the roller with the other face of the cam. The line bisecting the angle between the faces of the cam passes above the pivot pin 17 and shaft 12, so that the spring 23 offers more effective resistance to the upward than the downward movement of the lever, and operates to hold the switch closed with greater force than it operates to hold it open.
