Title: Improvements in the production of sulpho-aromatic fatty acids
IPC: C11C1/04
Filed: 1926-05-18
Abstract: 252,212. Petroff, G. May 18, 1925, [Convention date]. Splitting fats.-Sulpho-fatty-aromatic acids are isolated from the sulphonation mixture of non- saturated fatty acids and aromatic hydrocarbons, phenols or turpentine oils by washing out excess of sulphuric acid used in the sulphonation with water and a solution of common salt or other alkaline salts or dilute acetic acid, and dissolving the residue in petroleum, petrol, benzene, toluene, carbon tetrachloride, or other similar solvents. From these solutions the supho-fatty-aromatic acids are extracted with watery solutions of methyl or ethyl alcohol or with acetic or formic acid, and may be washed two or three times with a light petrol and evaporated. The sulpho-fattyaromatic acids thus obtained may be used for fat splitting. The petrol or similar solvent used yields fatty acids, insoluble, in water, which may be used in the fat industry. Specifications 4741/98 and. 9160/13 are referred to.

May 9, 1933, Nos. 13515, 13516, and 13517. Convention dates, May 9, 1932, May 9, 1932, and Dec. 15, 1932. [Class 39 (i).] A luminescent glass for the envelopes of electric discharge tubes, cathode ray tubes, or incandescent electric lamps is obtained by adding to a suitable glass a sulphide of zinc, barium, strontium, or calcium together with a compound of an " exciter metal in such proportion as is necessary to cause the sulphide to become luminous when exposed to radiation. The " exciter " metal may consist of manganese, copper, bismuth, thallium, rubidium, lead, antimony, cadmium, or tungsten. The sulphide may also be formed by the reaction of suitable compounds in the molten glass. The luminescence of articles made from the glass can be increased by reheating the articles, after formation, to a temperature somewhat above the softening temperature of the glass. When made into electric lamps, the luminescence of the glass can be used to modify the colour of the emitted light, and with electric discharge tubes, the glass may contain colouring or opaquing media for the same purpose. In some cases, the colouring or opaquing media may be contained in a glass which is formed into an outer layer covering the glass of the tube. In cathode ray tubes, employed for television, the glass renders unnecessary the use of a luminous screen to render visible the impact of the cathode stream on the envelope.
