Title: Method of extracting pentaerythryl-tetrakis- 3-(3,5-ditert. butyl-4-oxyphenyl)propionate  from the reaction mass obtained during synthesis of said product
Inventor: GLUSHKOVA LJUDMILA VASILIEVNA

Abstract: A method of extracting pentaerythryl-tetrakis-[3-(3,5-ditert.-butyl-4-oxyphenyl)propionate] from the reaction mass obtained during the synthesis of said product by means of reetherification of methyl ether 3-(3,5-ditert. butyl-4-oxyphenyl) propionic acid by pentaerythrite in the presence of an alkaline catalyst, and consisting of the desired product, initial non-reacted reagents, secondary reaction products, resinous oxidation products and residues of the alkaline catalyst, provides for treating the reaction mass with cyclohexane (the volume ratio between the reaction mass and the cyclohexane being 1:1.2-2) at a reaction mass temperature of 100-120 DEG C, separating by filtration the initial non-reacted pentaerythrite and the residues of the alkaline catalyst at a temperature of 60-75 DEG C, thus obtaining the cyclohexane solution of this desired product, the initial non-reacted methyl ether, secondary reaction products and the resinous oxidation products. The cyclohexane solution is cooled to a temperature of 15-20 DEG C, so as to obtain a crystalline sediment of a combination of the desired product occlusions with the cyclohexane. The sediment is separated by filtration and dissolved in normally structured hydrocarbons at a temperature of 45-75 DEG C and at a weight ratio between the sediment and the hydrocarbons equal to 1:1-2, respectively, the combination with occlusions being decomposed and the desired product being thus obtained. The desired product is extracted by crystallization from said hydrocarbons at 15-20 DEG C. The desired product is a highly effective non-toxic antioxidant for polymer materials.

Abstract: Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell. A reaction chamber within the shell receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and is provided with a thermal barrier in the form of a temperature resistant collar which is self-­supporting on a downwardly inwardly frusto-conical surface of the quench ring and is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.

The base is supported by a displaceable supporting device equipped with a guiding member, which imparts a direction change to the base. The supporting device at the deposition moves the base away below the material causing the material to be deposited by means of free fall. The material is positioned on the base a distance from the delivery end of the supporting device corresponding to the acceleration distance of the base. The rear end of the base is fixedly attached against displacement. The base is urged to make an abrupt direction change over a guiding member having a very small curvature radius (r) at the front end of the supporting device.

Abstract: Un matériau stratifié ou une pièce stratifiée comprend une couche de support et une couche fonctionnelle, notamment une couche de glissement, qui présente comme structure une dispersion solide ou fusible avec une matrice et au moins un élément dispersé dans la matrice, insoluble au moins à l'état solide dans le matériau de la matrice ou soluble dans celui-ci uniquement en quantités inférieures aux quantités utilisées. La structure de la couche fonctionnelle peut également comprendre une quantité fusible d'éléments mutuellement insolubles, ou mutuellement solubles uniquement en quantités inférieures aux quantités utilisées, éventuellement partiellement cristallins et utilisables à des fins tribologiques. On transforme la surface exposée de la couche fonctionnelle en une autre structure de l'alliage par dispersion par un traitement de surface, plus précisément par fusion suivie d'un refroidissement rapide depuis l'état fondu, de façon à provoquer une fine distribution des éléments non dissous et la consolidation dans cette zone superficielle du matériau d'une structure à fine dispersion. Cette zone superficielle peut avoir entre 20 mum et 500 mum d'épaisseur, de préférence entre 50 mum et 100 mum. Cette transformation de la structure est effectuée au moyen d'une flamme de plasma à champ d'action étroitement délimité que l'on déplace progressivement sur la surface à traiter. On forme avec la flamme de plasma, ou avec une pluralité de flammes de plasma adjacentes, un petit bain de fusion qui se refroidit immédiatement et très rapidement lorsque la flamme de plasma se déplace par rapport au matériau stratifié ou à la pièce stratifiée, se solidifie et forme ainsi une structure à fine dispersion.

Abstract: When processing an image it is often necessary to combine parts of its matrix mathematically, e.g. to multiply a part of this matrix with a given weighting function. In this context scalar products of vectors are important operations. 
For a real-time visualization of computer tomography pictures the calculation of said scalar products has to be as fast as possible. Normally the calculation of a scalar product of two vectors with two elements, respectively, requires two multiplications and one addition. The invention provides a coding procedure wherein two of the elements of said two vectors are transformed to one encoded element, respectively, and are then stored. This has the result that the calculation of said scalar product requires two encoding operations of the elements and one multiplication of the encoded elements. In this case, the coding procedure has almost no time-saving effect. But when calculating another scalar product with at least partly the same elements the encoding operations of a number of elements are already done and the stored encoded elements can be used. This has the consequence that the calculation of this other scalar product requires at least partly no encoding operations but only multiplications of the stored encoded elements. It is apparent that in this case the calculation of the scalar product can be more than twice as fast as the known normal calculation.
