Patent GB-737463-A (GB)
Title: Improvements in or relating to the preparation of potassium salts of alkyl sulphuricacids
Inventor: WINSOR PHILIP ALAN
Filed: 1952-05-05
Abstract: A potassium salt of an alkyl sulphuric acid is prepared by introducing into one end of a countercurrent system a sodium salt of the acid dissolved in a first solvent, and introducing into the other end of the countercurrent system an inorganic potassium compound dissolved in a second solvent, the two solvents being substantially immiscible with each other under the conditions of operation and such that, under the conditions of operation, the first solvent retains the sodium and potassium salts of the alkyl sulphuric acid largely to the exclusion of the inorganic compounds, and the second solvent retains the inorganic compounds largely to the exclusion of the sodium and potassium salts of the alkyl sulphuric acid.  Preferably the first solvent is an oxygenated organic solvent such as isopropyl alcohol, secondary butyl alcohol or methyl ethyl ketone and the second solvent is water.  The ratio of the two solvents may be between 1 : 3 and 3 : 1.  Potassium carbonate is the preferred potassium compound but the hydroxide and salts such as the fluoride or nitrate may be used.  The reaction may be carried out at room temperature or higher.  In examples (1) a mixture of sodium C10-C18 secondary alkyl sulphates dissolved in isopropyl alcohol is fed to the first stage of a four-stage countercurrent contacting apparatus at 50 DEG  C. while aqueous potassium carbonate is fed to the fourth stage.  The product dissolved in isopropyl alcohol is withdrawn from the fourth stage; (2) a similar mixture of secondary alkyl sulphates dissolved in isopropyl alcohol is treated in a seven-stage apparatus with aqueous potassium hydroxide.  Instead of multi-stage apparatus, a packed tower may be used or countercurrent equipment having rotating elements. Specification 537,255 is referred to.  The Provisional Specification describes also a batch process in which a sodium salt of an alkyl sulphuric acid is reacted with an inorganic potassium salt in the presence of a solvent in which the sodium salt of the inorganic acid is substantially insoluble as compared with the other components of the reaction mixture.  The solvent may be water. In example 3, a mixture of C10-C18 secondary alkyl sulphates is mixed with an aqueous solution of potassium carbonate.  After standing, the mixture separates into a lower inorganic layer and an upper organic layer containing the required potassium alkyl sulphate.

Title: Improvements in and relating to electric tele-transmission systems
IPC: G05D3/12
Filed: 1957-04-09
Abstract: 849,346. Electric correspondence control systems. CONTRANES A.G. April 9, 1957 [April 12, 1956], No. 11529/57. Class 40 (1).FIG. 3. In a system for causing a receiver shaft W2 to repeat the angular position of a transmitter shaft W1 the shaft W1 controls the frequency #1 of the output of an oscillator which is amplified and fed to a Wien bridge whose balance frequency #2 is determined by a receiver shaft W2 in exactly the same way as the frequency #1 is determined by transmitter shaft W1. Any difference between frequencies #1 and #2 produces an output voltage. from the bridge which is rectified in a. phase-sensitive rectifier, producing a D.G. voltage which is used to control a servo system driving shaft W2 until the error voltage is eliminated. As shown (Fig. 3) the frequency #1 of an oscillator O1 is determined by a Wien bridge including equal rheostats Rd adjusted by the shaft W1. The oscillator output is amplified and limited at EV and fed to a similar Wien bridge FD whose balance frequency f2 is determined by equal rheostats Rd adjusted by the shaft W2. If the frequencies f1, f2 are not equal an output voltage b is obtained from the bridge which is amplified and sent to a phase-sensitive detector D together with a reference voltage c obtained from the transmitted signal, whereby a D.C. voltage d is obtained whose magnitude and polarity are dependent on #1-#2. The voltage d is used to modulate at M an A.C. voltage e derived from a generator Gm to energise a motor Mot which drives the receiver shaft W2 to the position where the unbalance voltage b of the bridge FD is eliminated. Motor Mot also drives a generator Gen supplying an anti-hunting voltage. In a modification the system up to the modulator M is duplicated to cope with opposite 180 degrees of rotation, the modulator M being connected to the appropriate branch via a cam-operated switch driven from the receiver shaft W2.

Title: Dyeing organic derivative of cellulose textile materials
Inventor: SALVIN VICTOR SLUYTY
IPC: D06P3/44
Filed: 1952-05-07
Abstract: In the dyeing of textile materials of cellulose acetate or other organic ester or ether of cellulose by forming an azo dye on the fibre, coupling of the diazotized base is effected in the presence of a non-ionic surface-active agent selected from the group consisting of (a) condensation products (amide or ester) of alkylolamines with long-chain fatty acids, e.g. oleic, lauric, stearic or ricinoleic acid, such as the products sold under the Registered Trade Mark "Alrosol C" and under the Trade Name "Cerfak N-100", (b) polyethylene sorbitol esters of long-chain fatty acids, e.g. the polyoxyethylene sorbitol monolaurate sold under the Registered Trade Mark "Atlas Glozo", and (c) long-chain fatty acid esters of polyglycols, e.g. the polyoxyethylene glycol monolaurate sold as "Nonisol 100."  The surface-active agent is applied to the material as an aqueous alkaline solution after diazotization of the base has been effected on the material.  The coupling agent may be present on the material during the diazotization or it may be added to the material with the alkaline solution.  The process is particularly applicable to the use, as coupling agent, of an anilide, orthotoluidide or orthoanisidide of 2 : 3-hydroxynaphthoic acid with a diazotizable base capable of yielding a blue azo dye therewith, e.g. 4-benzoylamino-2 : 5-diethoxyaniline, 4-benzoylamino-2 : 5-dimethoxyaniline and 4-benzoylamino-2-methoxy-5-methylaniline.  In Examples cellulose acetate fabric is immersed at 75 DEG C. in a bath containing 4-benzoylamino-2 : 5-diethoxyaniline and the orthotoluidide of 2 : 3-hydroxynaphthoic acid.  Diazotization is then effected at 25 DEG C. with a sodium nitrite bath acidified with acetic acid.  The fabric is then rinsed and immersed in an aqueous bath of the surface active agent maintained at pH9 and 75 DEG C. Specification 706,735 is referred to.
