Title: A manufacture of chromiferous azo-dyestuffs
IPC: C09B45/48
Filed: 1933-11-08
Abstract: Chromiferous azo-dyestuffs are made by causing a chromiferous azo dye to react in an alkaline medium on the same azo dye free from chromium and containing at least once the residue of a coupling component whose coupling carbon atom belongs to a six-membered carbon ring. The dyes are superior in properties to those made in neutral or acid medium and give marine blue to black shades.  In examples: (1) the dyestuff 1-amino-2-naphthol-4-sulphonic acid --> b -naphthol is chromed with chromium formate and then heated with the chromium free azo dye in presence of caustic soda (marine blue or wool); (2) the chromium compound of the dye from nitrated 1-diazo-2-naphthol-4-sulphonic acid and b -naphthol is heated with the chromium free dye in presence of caustic soda (black); (3) and (4) as in (1) using tetramethylammonium hydroxide and ammonia respectively.  Examples of dyeing wool and silk and also of colouring a nitrocellulose varnish are given.  Dyes from diazotized o - aminophenols, o - aminonaphthols, o - aminobenzene-or naphthalene carboxylic acids and diazotized amines which contain a salicylic group or their derivatives, e.g. sulpho, nitro, halogen or alkoxy compounds are specified.  The usual inorganic and organic substances of alkaline action may be used in the condensation.  The dyestuffs may be applied according to Specifications 364,148 and 408,497 and may be used for wool, silk, leather, cotton, regenerated cellulose, cellulose esters and ethers, varnishes, or as pigments or in printing.  Specification 297,331, [Class 2 (iii)], also is referred to.
Patent GB-356008-A (GB)
Title: Improvements in and relating to metering devices
IPC: G01K17/08
Filed: 1930-10-17
Abstract: 356,008. Heat-measuring apparatus. CR•MER, M., 140, Avenue Victor-Hugo, and ALBAN•SE, G., 7, Rue du Bois, Asnieres, both in Paris. Oct. 17, 1930, No. 31174. Convention date, Oct. 29, 1929. [Class 97 (iii).] A heat-measuring device for determining the amount of positive or negative thermal units carried by a fluid comprises means for obtaining a proportionality between the rate of flow of the fluid through the device and the temperature difference between the fluid and a surrounding medium. The reading of a temperature indicator is proportional to the rate of flow of the fluid and also to the temperature difference, which is proportional to the initial temperature of the fluid. As shown in the Figure, the means for obtaining the proportionality between the rate of flow and the temperature difference comprises a container 2 forming a shunt circuit connected to the main conduit 4 by pipes 1 and 3. A constriction 5 or Pitot tube device in the main conduit produces a pressure difference between the ends of the shunt circuit proportional to the rate of flow in the main conduit. The container 2 may be provided with ribs, or the shunt circuit may take the form of a thin coiled pipe having a slightly enlarged portion at the end. The pipe 3 is formed with an enlarged portion 6 in which can be mounted a thermometer. The rate of flow in the shunt circuit is controlled by means of a valve 10. A remote indication may be obtained by mounting a thermopile 7 in the enlarged portion 6, and the indications may be integrated in an ampere-hour meter 9, such as an electrolytic device. The indications of several metering devices may be added by connecting the thermopiles in series with the meter.

Abstract: 410,161. Electrolytic production of antiseptic solutions. DESPLAT, R., and COMPAGNIE ELECTRO SALVATOR, 31, AllÚes de Tourny, Bordeaux, France. Nov. 5, 1932, No. 31288. [Class 41.] A solution for the production of an antiseptic is fed to an airtight electrolytic cell and passes thence together, if desired, with the gases evolved to the place of use, the factors regulating the degree of electrolysis, such as the effective area of the electrodes, their distance apart and the applied voltage, being regulated in accordance with the temperature, salinity and pressure or rate of supply of the incoming solution in such a way that the temperature of the outflowing solution is maintained constant at about 37-40‹ C. The solution mav contain 5.85 gms. of alkali metal chloride per litre a hypochlorite and oxygen, hydrogen and chlorine are produced. The apparatus shown comprises a cell 1 having a glass lid 2 made airtight with rubber packing 3. The solution entering at 5 passes a thermometer 21 controlling a variable resistance 22 in the circuit of an electromagnet 23 the armature of which regulates the position of a cranked electrode 7. The potential applied to the electrode 7 is regulated according to its position by a variable resistance 12. The treated solution leaves at 4 and passes to distributing devices such as a spray 57 or a jet 56 ; the device 55 permits treatment of a part by the rising gases issuing with the antiseptic liquid. The electrode 7 may be adjusted by a hand-wheel 8. The electrodes pass in an air-tight manner through platinum tubes welded in the lid. In a modification the electrodes consist of coaxial cones of which the inner one is adjustable and the outer forms the wall of the cell. The electric supply is obtained from the plate circuit of a rectifying valve 15 having an auto-transformer input 16. Solution flows in drops regulated by a pin valve 48 from a chamber 42 into a funnel 38 within a chamber 37 where it is mixed with water from a supply 35. The supply of the diluted solution is regulated by a pin valve 29 which simultaneously adjusts the position of an electromagnet 19 to effect a compensation regulation of a resistance 20 in the supply circuit. The main switch 18 is interconnected with cocks 45, 47 and a switch 13 whereby the current may be reversed in successive operations. In a modification the electrolyte is prepared in advance and is withdrawn from a heat-insulated storage tank by a pump actuated by an electric motor. In another modification the mother solution is mixed with water in a mixing turbine rotated by the supply water.
