Title: Improvements in or relating to the manufacture and use of wetting-out, equalising, peptising and cleansing agents
IPC: C07C305/10
Filed: 1932-05-04
Abstract: Products stated to be wetting, equalizing, peptizing and cleansing agents are obtained by esterifying with polybasic acids, the alkylene glycols obtained by addition of water to the unsaturated alcohols derived from natural fish and whale oils or fats by saponification. They yield dispersions of fats, waxes, fatty acids and other insoluble substances, and clear aqueous solutions with chlorinated hydrocarbons, hydrogenated phenols and alcoholic solvents.  In examples, (1) the fatty alcohols from sperm oil, after removal of solid constituents, are converted into glycols by treating with sulphuric acid and decomposing the reaction product with boiling water; a product which in solution cleans greasy wool is obtained by esterifying with chlorsulphonic acid and neutralizing with caustic soda; (2) products suitable as equalizing agents in acid dye baths, and as washing agents in the laundry are similarly prepared.  The use of phosphoric acid, polybasic organic acids, e.g. sulphocarboxylic acids and the unsaturated alcohols from spermaceti oil and bottlenosed whale oil is mentioned.ALSO:Products, stated to be wetting, equalizing, peptizing, and cleansing agents, and obtained by esterifying with polybasic acids, the alkylene glycols obtained by addition of water to the unsaturated alcohols derived from natural fish and whale oils or fats by saponification, may be employed to produce dispersions of fats, waxes, fatty acids and other insoluble substances, and p  clear aqueous solutions with chlorinated hydrocarbons, hydrogenated phenols and alcoholic solvents.

Abstract: 1,166,125. Gas turbine plant. CHEMICAL CONSTRUCTION CORP. March 20, 1967 [March 28, 1966], No.13048/67. Heading F1G. [Also in Division C1] An oxygen-containing gas stream from a compressor 2 is used to produce sulphur dioxide by burning a sulphur-containing feed in a furnace 10. The sulphur dioxide-containing combustion gas produced is catalytically oxidized in a converter 16 and washed with sulphuric acid in a tower 25 and the residual sulphur dioxide in the washed gas is subjected to a further catalytic oxidation in the converter 39 and passed to a second absorption tower 45, the residual gas from this second tower being expanded in a gas turbine 59. The turbine 59 may be used to drive the compressor 2 or an electric generator. Prior to the expansion the residual gas is heated by indirect heat exchange at 43 with the sulphur trioxide-containing gas from the catalytic oxidation, with the sulphur dioxide-containing gas from the furnace 10 or by burning methane in the residual gas in a catalytic combustion unit 56. The pressure in the sulphur burning furnace, the catalytic converter and the washing tower being maintained at 5-50 kg/cm<2> absolute.

Abstract: 1,177,176. Cyclone separators. BELOIT CORP. 22 March, 1967 [18 April, 1966], No. 13501/67. Heading B2P. A cyclone separator for removing foreign particles from a fluid suspension of solid particles comprises a conical chamber having a porous wall 20, a tangential inlet 10 for introducing the suspension to be cleaned in a chamber at the top of the conical chamber so that it passes in a vortical whirl through the conical chamber, a central outlet 40 for the cleaned suspension, a jacket enclosing the porous wall 20 and connected to a valved supply pipe 60 whereby liquid is forced through the wall 20 to form a layer on the inside surface of the wall, and a tip portion 30 having a non-porous wall and provided with a discharge opening for separated foreign particles. The inside diameter of the large end of the tip portion 30 is greater than that of the small end of the chamber to facilitate discharge of the foreign particles. The separator may be used to remove unwanted particles from wood pulp stock. The liquid forced through the wall 20 may be water and serves to release any light acceptable particles that may become entrapped with the unacceptable heavy particles on the wall of the chamber and cause them to discharge through the outlet 40. The layer of water formed on the wall also serves to protect the wall and to decrease frictional resistance thereby also facilitating the downward discharge of separated foreign partides. The separator may also be used for separating foreign particles from a gaseous suspension of solids. In this case the liquid layer on the wall serves to trap the separated particles and discharge them through the apex of the separating chamber. The liquid may also function as cooling and wear reducing agent when treating hot gases.
