Title: Process for the manufacture of azo-dyestuffs and intermediate products therefor
Filed: 1931-06-11
Abstract: Azo dyes are made in substance or on the fibre by coupling the diazo compounds of aromatic or heterocyclic amines containing no group inducing solubility in water with hydroxyindoles or hydroxynaphthindoles.  In examples, (1) cotton impregnated with 8-hydroxy-2-phenyl-a -naphthindole is developed with diazotized 2 : 5-dichloraniline, 2-chloroaniline, 2 - methyl - 4 - chloraniline, or 4-chloro-2-nitraniline, (2) cotton impregnated with 8-hydroxy - 2 : 3 - dimethyl - a  - naphthindole is developed with diazotized 2-nitro-4-chloraniline, 2-methyl - 4 - nitraniline or 2-methyl-4-chloraniline; 8-hydroxy-2 : 3-methylethyl or 2 : 3-diphenyl-a -naphthindoles may also be used, (3) cotton is impregnated with 7-hydroxy-2 : 3-dimethyl-a -naphthindole and developed with diazotized 2 : 5-dichloraniline or with 7 - hydroxy - 2 - phenyl - a  - naphthindole and developed with diazotized 2-chloraniline, 4-chloro-2-nitraniline, or 2-methyl-5-chloroaniline. Hydroxy-indoles and naphthindoles are made by subjecting to alkali fusion the sulphonic acids of Specification 385,605, but which are free from nitro or amino groups.  In an example, 2-phenyl-a -naphthindole - 8 - sulphonic acid is fused with caustic potash.

As shown in Fig. 1 a cylindrical member 2 such as a pin or stud forms one of a number of races symmetrically distributed over a flywheel 21 keyed to a rotary shaft 1, the disturbing forces in which are to be damped, and each race is surrounded by a hollow cylindrical mass 3. Excessive movements of each mass may be prevented by a second fixed pin covered with sound-damping material such as rubber or fibre and projecting within the periphery of the mass. In modifications (a) each cylindrical mass carries an eccentric peripheral portion ; (b) each mass is constructed as a half-cylinder having a slot for the passage of the pin 2 ; and (c) each mass is formed as a disc grooved to engage the end of the pin 2. Fig. 5 shows another construction in which a T-shaped mass 33 is slotted to engage a race 30 and carries an eccentric portion 34. The ends 32a, 32b of the slot may be covered with sound-damping material. Flexional and torsional vibrations may be damped by the construction shown in Fig. 6 in which a U- shaped member 36 the cross-piece 37 of which is curved longitudinally and in cross-section is formed on the shaft and carries one or more ring-shaped masses 38.

A portable instrument for measuring physical properties of the atmosphere in a building comprises a manually movable probe containing a plurality of electrical sensing elements responsive to indicate the magnitude of the different properties to be measured, a suitably calibrated measuring instrument, separate from the probe but electrically connected to it, and a selective switching means for directly connecting those elements responsive to the property to be measured into circuit with the measuring instrument. The probe has a casing 10 having an insulated base 16 and carried on the end of a rod, which may be telescopic, or consist of socketed sections, electrically insulated with PVC. The housing contains: two thermistors 40, 42 directly heated and responsive to air velocity, one being covered by a gauze and the other by a solid housing, to compensate for ambient temperature; two thermistors 44, 46 for measuring air temperature and humidity, 46 being contained in a sock 50 dipping into water holder 52; and one thermistor 48 protruding through wire mesh casing 10 and carried on a spring loaded arm so as to respond to surface temperature. In the measuring circuit (Fig. 6) switch 64 has positions Z (off), T(test), 1, 2 and 3, the numbered positions corresponding to various calibrations of meter 76. Switch 68 has positions D (dry bulb), W(wet bulb), S(surface temperature) and V (air velocity). Velocity thermistors 40, 42 are connected in parallel with each other and in series with a potentiometer 66 with a calibrated scale for extending the potentiometer scale. Humidity is calculated from the wet and dry bulb readings. In test position T of switch 64 standard resistor 78 is connected in circuit to test the battery voltage. Potentiometer 82 is provided to adjust the bridge voltage. Further batteries are provided for heating thermistors 40, 42. According to the Provisional Specification the air velocity is measured with only one separately heated thermistor, and separate thermistors are provided for the air temperature and dry bulb measurements.

Abstract: 617,970. Hooks and eyes ; fastening strips for personal wear. ISAACS, M. M. Dec. 19, 1945, No. 34428. Convention date, Jan. 11. [Classes 43 and 141] Each member of a hook and eye fastening for waistbands or the like comprises a base element the width and contour of which correspond with the width and contour of a pouch provided on the garment, so that when used the base elements transfer the closing strain uniformly over the entire width of the pouches, thus avoiding wrinkles where the garment is fastened. The hook member C, Fig. 2, comprises a thin plate element 10 which fits accurately into a pouch B, Fig. 1, in a waistband, and which has a bent-back tongue 11, the end 12 of which is bent again to form the hook proper. The eye member D, Fig. 3, has a similar base 13 which fits into a pouch B<1>, and which has a bent-back tongue 14 with spaced slots 15 in any one of which the hook may be engaged. Preferably the entrances E, E<1> of the pouches B, B<1> remain open, so that the fasteners may be easily removed, and in this case the tongues 11, 14 spring against their base plates, thus acting as clips. Alternatively the entrances may be closed by sewing. In a modification, the fasteners consist of frames, e.g. of pressed steel, having the same outline as before. Fig. 7 shows a further modification of this form wherein the hook member C2 has an expansion spring 36 between its tongue 31 and hook proper 32. The device is particularly applicable to waistbands with flaps made by a press folding process over a mould or die the shape of which corresponds to that of the base plates.

Passing materials through fluids and fluid-applying apparatus.-In apparatus for carrying out the process claimed in the parent Specification for the dyeing, bleaching, and analogous treatment of loose textile material in the unspun state, the container 9, 10 passes over a number of perforated cylinders 11 each loosely mounted on a fixed bearing comprising a hollow cylindrical member 14 connected by radial parts 15 to a perforated tubular part 13 through which the treating liquor is passed. The part of the bearing over which the container passes has short radial parts, and the member 14 is cut away to allow passage of the liquor. The perforations in the part of the cylinder 11 which are not covered by the container are closed by the member 14. The upper endless belt 9, forming part of the container is tensioned by a gravity roller 48 having adjustabla means for limiting its upward movement. The lower belt passes over rollers 54 below the treatment tanks and around adjustable rollers 58. The pairs of rollers 7, 8 between which the container is fed are pressed together by weighted lever and link mechanism 38, 39, 41. An adjustable, screw 45 acting on the bearing of the roller 7 passes through a nut on the lever 38 which normally rests on a projection and limits the upward movement of the roller 7, but it can yield when an abnormally thick part of the container passes between the rollers.
