Abstract: A method is disclosed for reusing the processing condensates in a combined plant for the production of ammonia and urea. The condensates are combined into a single stream, filtered to remove the solid substances in suspension, if any, and fed to a boiler for the production of steam while exploiting the sensible heat. Pollution of sewage waters is prevented while obtaining a considerable economy in the running costs.

Abstract: Fibres for biological uses can be produced by adding to a spinnable solution of a polymer selected from among many of the most common polymers and copolymers, a substance selected from among anti-platelet aggregation substances, anticoagulants and substances having a similar action. The substances can also be applied as a surface outer layer to articles made with the polymeric substances.

Abstract: A process for recovering power is disclosed, by which excess electric power is exploited for electrolyzing alkali metal hydroxides (molten) and the thusly obtained pure alkali metals are stored. When the demand of electric power becomes critical, the alkali metals are reconverted into their hydroxides and the reaction heat, along with the hydrogen produced in the reaction, is recovered to produce steam: the latter can be used either to produce electricity, or to use its heat, or both.

Abstract: A method for preparing nontoxic, edible proteinic concentrates adapted also for human nutrition, is disclosed according to which undesirable compounds such as polyphenols (e.g. chlorogenic and caffeic acids) are complexed by aluminum salts to prevent oxidizing these polyphenols to quinones. It is important that aluminum be constantly kept in soluble form to prevent it from being precipitated together with the proteins when protein-precipitating acidification is carried out. Citric acid has been found to be the best complexing agent.

Abstract: For effecting enzymic reaction, a reactor is disclosed, in which the flow of the solution to be treated through the catalytic bed material takes place radially. It is preferred to have the catalytic bed in the form of coils of enzyme-occluding fibers. The coils are variously piled up within the reactor. High outputs, low pressure drops and more than satisfactory conversion rates are obtained.

Abstract: 1505404 Isomerizing alkenes SNAMPROGETTI SpA 17 July 1975 [2 Aug 1974] 30141/75 Heading C5E Alkenes are isomerized with a silica-surface - modified alumina catalyst which has been produced by impregnating alumina with an organosilicon compound containing radicals, at least one of which is other than OH, pyrolysably bound to silicon, and subjecting the treated alumina (substantially free from unreacted impregnating material and any volatile reaction products) to calcining. The alumina may contain 0À5-12 wt. per cent of surface-modifying silica. Preferred organosilicon compounds are esters of orthosilicic acid. Examples describe the isomerization of butenes and pentenes.
