Abstract: A process for increasing the viscosity of a technical grade alkali metal phosphate modified starch obtained by the reaction of starch with an alkali-metal orthophosphate at a temperature between 120 DEG and 175 DEG  C., comprises dispersing between 15 and 35 weight per cent of said technical grade starch phosphate on an aqueous solution containing between 20 and 45 volume per cent of an inert oxygen-containing water-miscible organic liquid; agitating the resulting dispersion and treating it with chlorine until the supernatant liquid assumes a green colour; separating the solids from the liquid phase; washing the separated solids with an inert oxygen-containing water-miscible organic liquid; and recovering an alkali-metal phosphate-modified starch of substantially increased viscosity.  The viscosities obtained may be 50,000 to 100,000 centipoises measured in a 5% aqueous solution at 25 DEG  C.  The starch phosphate starting material may be obtained by immersing dry, ungelatinized starch on an aqueous solution of alkali-metal orthophosphate, removing the liquid phase, drying the solids to less than 15% moisture content and heating for 1-15 hours at 130-170 DEG C., as disclosed in Specifications 812,363 and 812,339.  The organic liquid in which the starch phosphate is dispersed may be acetone, dioxane, tetrahydrofurfuryl alcohol, methanol, ethanol, n-propyl alcohol, iso-propyl alcohol, ethylene glycol, propylene glycol, glyecerol, ethylene glycol methyl ether, diethylene glycol ethyl ether, or diethylene glycol diethyl ether.  The dispersion is preferably agitated at room temperature or lower.  Chlorine treatment is suitably carried out by bubbling chlorine gas through the agitated dispersion. Washing of the separated solids is preferably effected by an aqueous solution of the organic liquid used on making the dispersion, with subsequent removal of water by washing with dry organic liquid.  The product may be dried in air at a temperature not exceeding 80 DEG  C. Specification 857,868 also is referred to.

Abstract: Coal washery effluent is clarified by adding thereto a coagulating agent such as aluminium sulphate or sodium aluminate, e.g. between 20 and 200 parts by weight of the former to one million parts of the effluent, and silica sol containing 1 mole of caustic alkalinity (Na2O or NaOH) per 10 - 50 moles of SiO2 and preferably containing between 0.1 per cent and 3 per cent of SiO2, and thereafter separating the coagulated material from the water.  Sufficient sol to contain between 10 and 100 parts and preferably between 20 and 50 parts by weight of SiO2 may be added to one million parts of the effluent, preferably after the coagulating agent.  The silica sol may be obtained by partially neutralising a cold sodium silicate solution with cold dilute mineral acid, e.g. 5 per cent H2SO4 to give, e.g. a solution containing 0.5 - 5 per cent SiO2 and caustic alkalinity equal to 0.01 to 0.2 per cent Na2O, while stirring thoroughly, allowing the mixture to stand and diluting.

In a process for the surface treatment of a semi-conductor element which has a metal electrode thereon, a jet of oxidizing fluid is directed on the semi-conductor surface at the same time as a jet of fluid at a much lower temperature is directed on the electrode. In the embodiment (Fig. 2) an aluminium foil is laid upon a molybdenum disc 22 and a silicon disc 21 on the aluminium followed by a gold-antimony foil 23 on the silicon. The assembly is heated in graphite powder at 800‹ C. to alloy the parts together and provide two contact electrodes 22 and 23 to the silicon disc 21, after which the semi-conductor surface is etched and rinsed. The assembled element is mounted upon a rotatable metal holder (Fig. 1, not shown) and whilst the holder is rotated a jet of superheated steam is directed by a nozzle on the surface of the semi-conductor producing an oxide coating thereon, and a jet of cooler distilled water is directed on the metal electrode to prevent its melting. With multiplering arrangements of electrodes on the body surface a plurality of superheated steam nozzles may be employed. Air or pure oxygen may replace the steam and a pure hydrogen flame may play on the surface of the body. The cooling medium may be water, air, nitrogen or an inert gas such as argon. Silicon or germanium devices are described, doped with phosphorus or aluminium and incorporating indium and gold electrodes. Processes involving doping of a semi-conductor element through gaps in a silicon oxide mask pattern are also referred to as is the principle of doping a semi-conductor body by incorporation of the impurity dopant in the oxide layer. The devices to which the invention is applied include diodes, transistors, photo-sensitive devices and four-layer devices.
