Abstract: A continuous process for the production of a granulated fertilizer wherein comminuted phosphate rock, phosphoric acid and water are introduced into a pre-reactor where they are heated. The mixture is continuously withdrawn and transferred to a digester where heating is continued resulting in formation of a slurry. The slurry is continuously withdrawn and is split into two streams, one of which is recycled to either the pre-reactor or to the digester while the other stream is delivered to a granulator where it is mixed with other fertilizer ingredients and dried to form the granulated fertilizer.
Abstract: A binder and a hardener therefor for a foundry aggregate. The binder is a resin obtained by reacting phosphoric acid with a mineral silicate. The hardener is a linear alkali metal polyphosphate, ammonium polyphosphate, a source of polyvalent cations, potassium olivine phosphate and other metal silico-phosphates or aluminum dihydrogen phosphate or mixtures there.
Abstract: A combination of foundry aggregate, binder and hardener for the foundry aggregate wherein a linear metal polyphosphate or ammonium polyphosphate is used as the binder, and the hardener is phosphoric acid or a mixture of phosphoric acid and a source of polyvalent metal cations.
Abstract: A hydrogel binder for a foundry aggregate comprising, in combination, a metal silico-phosphate and as a hardener therefor a mixture of aluminum dihydrogen phosphate, water and phosphoric acid.

Abstract: A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is a high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing "scaffolding" and improving the operation of the furnace. The disclosure further includes improvements in which olivine is mixed with iron bearing materials or with coke and such mixture is formed into agglomerates having improved properties and in which such agglomerates are charged into the furnace.
Abstract: A method for oxidation of reduced cations and humate constituents of filtered, wet process phosphoric acid comprising the step of treating the acid with an oxygen source in the presence of activated carbon.
Abstract: An improved process for preparing foundry cores and molds using a foundry aggregate and a binder therefor wherein the aggregate is mixed with an aqueous suspension of cereal flour and then with a core oil, the improvement comprising mixing the aggregate with phosphoric acid or sulfuric acid before mixing with the aqueous suspension of the cereal flour.
Abstract: Manganese complexes of various monovalent and divalent polyether antibiotics are provided which act as coccidiostats and growth promoting agents when administered to food-producing animals such as cattle, sheep, swine and poultry. Soluble manganese salt is added to a fermentation beer containing the polyether antibiotics to form an insoluble, recoverable biomass containing the desired manganese antibiotic complex. This biomass, in a dried form, can be given orally to animals such as cattle, sheep, swine and poultry.The subject manganese complexes include: linear monovalent and divalent polyethers (monensin, nigericin, lasalocid, lysocellin, etc.); non-glycolic monovalent monoglycoside polyethers (septamycin, dianemycin, lenoremycin, carriomycin and antibiotic A-204); mononitrogen-containing divalent pyrrole ethers (calcimycin, X-14547, etc.); polynitrogen-containing divalent pyrrole ethers (A-23187, etc.); glycolic monovalent monoglycoside polyethers (etheromycin, etc.

Abstract: Aqueous ammonium uranyl tricarbonate strip solution is purified by using activated carbon to remove ammonium di(2-ethylhexyl)phosphate impurity.
Abstract: In combination, a binder for a foundry aggregate and a hardener therefor, as the binder, polyvinylammonium phosphate and, as the hardener, a linear alkali polyphosphate, ammonium polyphosphate, a source of polyvalent metal cations, orthophosphoric acid, or mixtures thereof.
Abstract: An improved method of treating fabrics made with natural fibers using hydroxymethylsulfonate to render the fabrics wrinkle resistant. According to the improved process, an alkylene glycol is incorporated in the sodium hydroxymethyl sulfonate padding bath used to impregnate the fabric thereby surprisingly reducing the amount of extractable formaldehyde from the dried fabrics.
Abstract: A binder composition for a foundry aggregate and a hardener therefor, as the binder, polyvinylammonium phosphate and, as the hardener, a linear alkali polyphosphate, ammonium polyphosphate, a source of polyvalent metal cations, orthophosphoric acid, or mixtures thereof.
Abstract: A process for the consolidation of mineral slimes resulting from the beneficiation of ores comprising the steps of mixing the slimes with a microorganism species or a mixture thereof or ruptured or dried cells thereof, or a fermentation beer on which the organism was grown wherein the organism is selected from the group of cyanobacteria and allowing the mixture to separate into a clear upper layer and a consolidated slimes lower layer.

Abstract: A method of promoting growth and enhancing feed efficiency in meat producing animals. The 6' esters of zearalanol are effective growth promoting agents in meat producing animals, particularly ruminants, when implanted subcutaneously in said animals to obtain a controlled release of the compositions.Included in this group of compositions are: zearalanol 6'-butyrate; zearalanol 6'-decanoate; zearalanol 6'-hexanoate; zearalanol 6'-laurate; zearalanol 6'-trichloroacetate; and zearalanol 6'-trifluoroacetate.
