Abstract: Method for linking reloaded program modules on a smart card with likewise reloaded libraries, in which the method is split into two portions. The first portion can be carried out at any instant after the program module has been compiled. Only the second portion, in which the dynamic references are resolved, needs to take place after the program modules have been loaded on the smart card.

Abstract: A water sensitive ceramic powder, in particular aluminum nitride, is provided with a hydrophobic coating. The coated powder is dispersed in water with addition of a binder and a nonionic surfactant from the group comprising ethylene oxide adducts with an HLB value of from 10 to 14. Subsequently the aqueous slip is converted into a free flowing granulated powder. The nonionic surfactant, which is added in an amount sufficient to give a monomolecular layer, makes possible a good dispersion of the hydrophobically coated powder in water.

Abstract: An aluminum nitride powder has a crystallite size of 40 to 150 nm, measured by powder diffractometry and evaluated by the method of Scherrer, a primary particle size of 0.1 to 0.5 .mu.m, a specific surface according to BET of 5 to 50 m.sup.2 /g and a degree of whiteness of more than 91%, measured using light of a 400 to 700 nm wavelength against barium sulfate analytical reagent as standard of whitness.To prepare this aluminum nitride powder, metallic aluminum and monoamminealuminum chloride [AlCl.sub.3 (NH.sub.3)] are first molten together in an inert gas atmosphere at temperatures above 125.degree. C. and allowed to react with one another with evolution of hydrogen. 8 to 20 g of ammonia are then introduced per hour per mol of monoamminealuminum chloride into the aluminum-containing monoamminealuminum chloride melt at temperatures between 250.degree. and 400.degree. C., aluminum nitride being precipitated as a solid until the conversion of the aluminum is complete.

Abstract: The invention relates to a process for separating seminoble and/or noble metals from an aqueous solution having compounds of these metals dissolved therein by subjecting the solution to reaction with red phosphorus. More particularly, the solution is conveyed through a zone containing a layer of granular red phosphorus particles with a size of 0.01 to 10 mm, which may be used in admixture with active carbon.

Abstract: The invention relates to the continuous production of phosphine. To this end, elemental phosphorus is reacted with an aqueous alkali metal hydroxide solution and at least one alcohol, the reactants being used in admixture with 0.01 to 2 weight % of a surfactant, the percentage being based on the alcohol.

Abstract: Phosphine is continuously produced by reacting yellow phosphorus with an aqueous alkali metal hydroxide solution in the presence of an alcohol, with the exclusion of oxygen, at 44 to 90.degree. C. To this end, the reaction is effected in two separate reaction stages. In the first reaction stage, the alkali metal hydroxide solution and phosphorus are reacted with agitation in a molar ratio of 0.7:1 to 0.9:1 and the resulting gaseous phosphine is collected. Resulting liquid phase material containing unreacted phosphorus is delivered to the second reaction stage in which the unreacted phosphorus is reacted with further aqueous alkali metal hydroxide solution. The resulting gaseous reaction products are collected separately from the gaseous phosphine collected in the first reaction stage.

Abstract: Phosphine is produced from elementary yellow phosphorus and an aqueous alkali metal hydroxide solution in the presence of an alcohol. The phosphine is more particularly made by using an alcohol having from 5 to 10 carbon atoms and a dissolving power for yellow phosphorus of more than 5 g/l; suspending the phosphorus with agitation in the said alcohol in a reaction zone; reacting the resulting suspension with the alkali metal hydroxide solution at temperatures lower than the boiling point of the alcohol; and collecting the resulting issuing gaseous phosphine.
