Title: Azo dyestuffs of the pyrazolone series
IPC: C09B62/44
Filed: 1960-01-27
Abstract: The invention comprises dyes of formula:-  <FORM:0879641/IV(c)/1> where R1 is an alkylene radical of 2-4 C atoms between N and X, X is halogen, OSO3H, OSO3Y or OSO2R where Y is an alkali metal cation and R is an aliphatic or aromatic residue, R2 is the residue of an isocyclic or heterocyclic compound and n is 1-4.  The dyes are made by conventional methods of diazotization and coupling or by treating corresponding dyes containing a group R1OH with the reagents required. Representative of specified diazo and tetrazo components are aniline- 3-sulphonic acid, 1-amino-4, 5-dichlorobenzene- 2-sulphonic acid, 4-aminodiphenyl- 3-sulphonic acid, anthranilic acid, 2-naphthylamine-4, 8-disulphonic acid, 2-amino-1, 3, 5-thiodiazole, 3-amino-1, 2, 4-triazole, 2-aminobenzthiazole, 4, 41-diaminodiphenyl, 4, 41-diamino-stilbene-2, 21-disulphonic acid, 3, 31-diaminodibenzene sulphimide and the reaction product of copper phthalocyanine trior tetra-sulphochloride with 3 or 4 mols of 1, 4-diamino-benzene- 3-sulphonic acid.  Representative of specified values for -R1 X are CH2CH2Br, CH2 CH OH CH2 Cl, CH2 CH2 OSO3 H CH2 CH2 OSO3 Na, <FORM:0879641/IV(c)/2> and CH2 CH2 OSO2 CH3.  The dyes colour natural and regenerated cellulosic materials preferably from an aqueous solution in conjunction with an alkaline treatment.

Filed: 1926-02-09
Abstract: 270,421. McLachlan, N. W. Feb. 9, 1926. Loud-speakers; magnetic instruments; diaphragms. - Electromagnetic acoustic apparatus comprises a coil 1 mounted so as to be capable of vibration about an axis 2 in a magnetic field 20 and connected to a diaphragm 13, the periphery 15 of which is substantially unconstrained in the direction of vibration. The axis of the coil may be pivoted on bearings or clamped to furnish a torsional restoring-force. The passage of oscillating currents through the coil gives rise to rotational oscillations which cause vibration of the diaphragm through a member 16 disposed on a tangent to the solid of revolution of the coil about the axis. The magnet 6 which furnishes the field is mechanically insulated from its support by felt 8. The periphery of the diaphragm rests in a V- shaped annulus. The diaphragm may operate into a horn or funnel-shaped flare. One side of the diaphragm is wholly or partially enclosed in a non-resonant enclosure 18 filled with expanded cotton wool or provided with one or more non- reflecting partitions. The partitions may support the diaphragm. Alternatively the chamber 18 is made resonant to a fixed or variable frequency. Two or more diaphragms may be arranged round a common container and actuated by separate coils which are arranged in magnetic air gaps in series with one another and are fed with electric oscillations controlled by a common source. The coil may be associated with a tuned electric circuit, a filter circuit or a volume control circuit which may be coupled electromagnetically to the coil by a member vibrating with it.
