181	Preparation of ultrafine mixed metallic-oxide powders	US3681010D	1970-09-14	US3681010A	1972-08-01	MESSIER DONALD R; GAZZA GEORGE E
A METHOD FOR THE PREPARATION OF ULTRAFINE MIXED METALLIC-OXIDE POWDERS COMPRISING THE STEPS OF: COMELTING STOICHIOMETRIC AMOUNTS OF HYDRATED NITRATES OF A LEAST TWO CATIONS, FREEZING THE MELT TO PRODUCE AN INTIMATE MIXTURE OF THE SOLID HYDRATED NITRATES, PARTIALLY DEHYDRATING THE SOLID MIXTURE AT A SUBLIQUIDUS TEMPERATURES AND HEATING THE DEHYDRATED MIXTURE IN ORDER TO DRIVE OFF THE NITROGEN AND DECOMPOSE THE MIXTURE TO THE OXIDE.
182	Hollow spherical articles	US3674461D	1970-05-21	US3674461A	1972-07-04	FARNAND JOSEPH REDMOND; PUDDINGTON IRA EDWIN
HOLLOW ARTICLES FREE OF HOLES OR SEAMS OF A METAL SELECTED FROM ALUMINUM, MAGNESIUM, BORON, AND BERYLLIUM ARE PROVIDED BY COATING A SHAPED CORE OF A MATERIAL TRANSFORMABLE DIRECTLY INTO GAS WITH FLAKES OR PARTICLES OF THE METAL, SLOWLY REMOVING THE CORE MATERIAL THROUGH THE PARTICULATE COATING IN GASEOUS FORM, AND CONSOLIDATING THE COATING (E.G. BY FUSING OR SINTERING). COATINGS OF THESE METALS CANNOT BE SATISFACTORILY PREPARED BY REDUCTION OF THEIR SALTS IN SOLUTION. SMALL SPHERES OF A DIAMETER LESS THAN 0.2 INCH (ESPECIALLY 0.005 TO 0.06 INCH) ARE OF PARTICULAR INTEREST.

184	Method of making spherules of a crystalline nuclear fuel carbide	US27264D	1965-08-20	USRE27264E	1972-01-11
METHOD OF PRODUCING NUCLEAR CARBIDE SPHERULES WHEREIN NUCLEAR PARTICLES OF CARBIDE OR OTHER COMPOSITION, ARE HEATED IN AN ISOLATING MEDIUM SUCH AS CARBON TO THE FUSION TEMPERATURE TO PRODUCE SPHERULES. WHEN STARTING WITH NON-CARBIDE PARTICLES ENOUGH CARBON IS INCLUDED TO FORM THE CARBIDE. THE SPHERULES ARE THEN GIVEN A PYROLYTIC CARBON COATING.

Free-flowing, fast-dissolving, completely soluble, strong, granular particles containing a mixture of a hydratable alkali metal phosphate and an alkali metal silicate wherein the SiO2 to said phosphate mole ratio is at least 1:1, were produced by maintaining the alkali metal phosphate at a temperature of 60* to 100* C., gradually adding an aqueous solution of alkali metal silicate to the alkali metal phosphate, continually evaporating water from the resulting mixture, controlling the rate of addition of the alkali metal silicate solution so that the resulting mixture is maintained in the form of discrete particles, continuing said alkali metal silicate addition until the discrete, granular particles have an SiO2 to said phosphate mole ratio of at least 1:1, and recovering dry-appearing, granular particles which yield a pH of at least 10.5 in an aqueous 1 percent solution.

FREE-FLOWING FUSED BEADS OF NORMALLY SOLID, THERMOPLASTIC ORGANIC POLYMERS SUCH AS POLYETHYLENE ARE PREPARED BY (1) SUSPENDING A FINE POWDER OF THE THERMOPLASTIC POLYMER IN AN AQUEOUS MEDIUM CONTAINING A SMALL AMOUNT OF A NON-REACTIVE, INSOLUBLE SUSPENDING AGENT SUCH AS ZINC OXIDE, (2) HEATING THE RESULTING SUSPENSION TO A TEMPERATURE AT OR ABOVE THE MELTING POINT OF THE POLYMER WHILE SUBJECTING THE SUSPENSION TO AGITATION AND (3) COOLING THE SUSPENSION UNDER CONTINUED AGITATION.
188	Method for agglomerating suspended particles	US3577489D	1968-04-26	US3577489A	1971-05-04	ROSENTHAL CHRISTIAN
A PLURALITY OF FINELY SUBDIVIDED SOLID PARTICLES IS CONVERTED INTO A MASS OF DISTINCT AGGLOMERATED BODIES BY SUSPENDING THE SOLID SUBDIVIDED PARTICLES IN WATER HEATED TO AT LEAST 80C. THE PARTICLES MUST BE SUCH THAT WATER IS INERT THERETO AND WHICH ARE AT MOST SLIGHTLY SOLUBLE IN WATER. THE GRANULATING AGENT IS A SYNTHETIC ORGANIC PLASTIC WHICH IS DISSOLVED IN A LIQUID ORGANIC SOLVENT AT AT LEAST 80C. THE GRANULATING SOLUTION IS THEN ADDED TO THE SUSPENSION AND THE THUS-FORMED MIXTURE IS MAINTAINED, PREFERABLY UNDER STIRRING, AT AN ELEVATED TEMPERATURE BELOW 100*C. AND SUFFICIENTLY HIGH TO FORM GRANULES OF THE FINELY SUBDIVIDED PARTICLES AND THE GRANULATING AGENT SO THAT A PLURALITY OF AGGLOMERATED BODIES EACH COMPRISING A PLURALITY OF THE FINELY SUBDIVIDED PARTICLES ADHERED TO EACH OTHER BY THE GRANULATING AGENT WILL BE OBTAINED.

1,051,334. Spray-producers. SOUTH AFRICAN IRON & STEEL INDUSTRIAL CORPORATION Ltd. July 25, 1963 [Aug. 1, 1962], No. 29512/63. Heading B2F. [Also in Division C7]. Irregularly shaped particles are spheroidised by swirling them through a flame to melt them at least at their surfaces and then allowing them to pass into a cooling zone. The particles may be of Fe/Si (10 to 25% Si) and may contain Cu or Al. As shown, irregularly shaped particles are fed through a hopper 1 to a Venturi-tube 7 where they are dispersed in preheated air fed from a pipe 5. Combustible gas, supplied through a pipe 11, is fed into a chamber 12 tangentially and thereby swirled. This swirling gas then swirls the air and dispersed particles as they issue from an outlet 9 of a discharge tube 4. The particles swirl through oxidising and reducing zones 14 and 15 of a flame 13, are heated and spheroidised. They pass into a cooling chamber 23 and solidify. The nozzle is provided with a water cooling jacket 22 and reducing gas is fed through a surrounding passage 18 to provide an envelope to the flame. The amount of swirling of the particles can be adjusted by raising or lowering the discharge tube 4. A small proportion of combustible gas may be mixed with the air. Cooling medium for the cooling chamber 23 is supplied through an annular inlet 24 and may also be supplied tangentially to the chamber.
