Preferably the catalyst has a grain size of 100 to 250.mu.. The molar ratio of the air to the monoalkylpyridine can be from 80:1 to 300:1, and preferably is from 150:1 to 260:1. The molar ratio of the ammonia to the monoalkylpyridine can be from 3.5:1 to 12:1, and preferably is from 4:1 to 9:1.

Abstract: In a typical pulp mill bleaching process, a pulp slurry is subjected to one or more chlorination treatments, each being followed by a caustic extraction stage. To decrease the volume of effluents, water re-use is practiced with a portion of the first caustic extraction stage filtrate being reused for direct countercurrent washing to increase the concentration of the filtrate and the balance thereof being removed as a concentrated caustic extraction effluent. According to the novel feature, the caustic extraction effluent removed, having a pH of about 9 to 12, is combined with an acidic solution having a pH of less than about 1.5 to form a combined effluent having a volume of less than about 2500 gallons per air dried ton of bleached pulp and a pH below about 2.8, whereby a precipitate is formed which removes organic color bodies from the combined effluent. Part or all of the acidic solution is preferably a concentrated chlorination effluent obtained by recycle of the chlorination stage washer filtrate.

Abstract: A process for incorporating a superconductive compound or compounds by fusion in a base metal having good electrical and heat conductive properties, such as copper, silver, aluminum, and the like. The process involves preparing a melt of the base metal and of the alloy components which combine to form the superconductive compound or compounds having a .beta.-W (A 15) structure. Then the melt is solidified at a cooling rate of at least 1000.degree. C./sec. whereby a ductile superconductive alloy is formed wherein the individual particles of the superconductive compounds are finely distributed in the base metal and are mutually spaced with respect to each other in such a way that the critical value for the tunnel effect is not exceeded.

Abstract: The improvement in the process for recovering zinc from ferrites which includes treating electrolytic zinc plants residues with a sulfuric acid solution to dissolve the zinc and metals, a solution resulting which contains sulphates of zinc and the other dissolved metals. The undissolved residue is separated in a certain manner from the solution. The solids-free solution is neutralized in a second step with calcine or another neutralizing agent containing zinc until a certain acidity is reached so that the iron remaining in solution separates therefrom in the form of its complex basic sulfate. The solids are settled out and then sent to a neutralization step, which is part of the residue separation scheme, where they are used as seeds of crystals of complex basic sulfate of iron which helps to remove iron in the first neutralization step. This final solution is added to the normal circuit or process flow path of electrolytic zinc plants. Any Fe.sup.+.sup.

Abstract: The specification describes the total synthesis of L-norleucine-13-motilin ased on the replacement of the L-methionine radical located in the 13-position by an L-norleucine radical. In accordance with the present day development of peptide synthesis the central arginyl-methionyl-bond (amino acids 12 and 13 of motilin) can in practice hardly be synthesised, while on the other hand the norleucine-13-docosapeptide corresponding to motilin can be more readily produced synthetically, and this provides for a comparatively rapid determination of structure and can give important information as regards the biological effect specificity of methionine.

Abstract: Fatty acid amide coated pigments are obtained and used to formulate with uncolored thermoplastic materials. The colors of the pigments are fully developed and extremely high pigment loadings are obtained. The coated pigments are formed by admixing the pigment with melted fatty acid amide; solidifying the material by cooling it; grinding the material; and separating out the fines. The coated pigments particles are compounded with thermoplastic materials by low shear means, such as, injection molding. An improved form of the coated pigments can be obtained by admixing the melted fatty acid amide, and the pigment; extruding the admixture to form a creamy mass; solidifying and forming the creamy mass by passing it through cold and forming rollers; grinding the resultant wafer-like material; and separating out the fines.

Abstract: An encapsulating agent and a nutrient are admixed, and then the encapsulating agent is gelatinized or polymerized under high temperature and pressure so as to encapsulate the nutrient. The encapsulation allows the nutrient to be kept in a dry stabilized state for a long period of time without the loss of potency. Further the encapsulation allows the nutrients to be released into the digestive tract after a predetermined amount of time. The digestive tract solubilizes or digests the encapsulating agent thereby freeing the nutrient. Encapsulation is preferably conducted using a heated extruder or expander. The encapsulating agent may be a high protein vegetable composition, such as, wheat flour gluten, a grain flour or carbohydrate flour. The nutrients may be in particulate or liquid form and can be such things as vitamins, amino acids, lipids, enzymes, inorganic salts (minerals). Additives such as surfactants, can be incorporated into the admixture before the extruding step.
