The invention describes a method to convert geological response data to graphical raw data by using at least one stream processor for this purpose. The geological response data is pre-processed by a CPU and the preprocessed geological response data is fed into one or more stream processors. The stream processor then does the calculation intensive work on the preprocessed geological response data and returns the processing results back to the CPU which does some post-processing on the results coming from the stream processor. Stream processors comprise single or multiple programmable GPUs, clusters/networks of nodes with one or several GPU's; cell processors (or processors derived from it) or a cluster of cell processor nodes, game computers (in the spirit of Sony's PlayStation, Nintendo's GameCube, etc.) or clusters of game computers.
The present invention concerns an apparatus for gripping, holding and releasing objects (30) that can be penetrated. The apparatus includes at least two needles (1, 2) with a central axis in the longitudinal direction of the needle placed at a distance from each other. At least one drive unit is connected to the needles (1, 2) for driving these between an extended and a retracted position. At least one of the central axes of the needles forms a part of a circle when this needle is in an extended position. Furthermore it is described a method to grip, hold and release objects (30) that can be penetrated.
An apparatus for a burst safe pressure-neutral high pressure cylinder in pVT and condensate cells is described. The dimensions of an outer cylinder are such as to prevent plastic flow of the inner cylinder wall caused by elevated inside pressure and/or temperature.
A magnetic stirring system for pVT and condensate cell is described. The stirring detection is performed by a solenoid to achieve reliable monitoring of the rotation of the stirring impeller in high-viscous fluids, dark fluids or cells without window.

The present invention relates to an apparatus for separating a fluid flow, the fluid flow comprising lighter and heavier fractions to be separated from each other, the apparatus comprising at least one inlet (22) and at least two outlets (5, 23), the apparatus further comprising a rotary centrifuge device (1), the lighter fractions being carried further on through one of the outlets (23) and the heavier fractions being carried through the other one of the outlets (5). The invention is characterized in that a spin-up assembly (17) is arranged upstream of the rotary centrifuge device (1), the spin-up assembly (17) being configured in such a manner that the fluid flow entering the rotating cylinder (1) is imparted a rotational movement, the rotational velocity of the cylinder (1) being adjustable so that the relative velocity difference between the rotating movement of the fluid flow and the rotational velocity of the centrifuge device (1) is optimal in terms of separation.
The present invention relates to a method for delaying the ageing, or lower the rate of degradation and loss of physical strength, of a cellulosic insulation e.g. used in an apparatus such as a power transformer, an electrical apparatus or an electrical cable. The invention is achieved by that at least two ageing inhibitors in the form of active chemical substances are added to the oil in the apparatus and at least partly be absorbed by the cellulosic insulation, a first active chemical substance is a buffer substance, such as oil soluble amines- or ammonium salts, and a second active chemical substance is an oil soluble alcohol, and thereby achieving a deceleration of both the acid hydrolyses process and the oxidation process resulting in a lower rate of cellulose degradation and maintaining the strength of the cellulosic insulation.

Polybranched, particulate, organic/ inorganic hybrid polymer in the form of a sol-gel product having the basic structure: Formula (I) where X is a linakge group chosen among C1-C18-alkylene and arylene, R1- R6 are chosen among hydrogen, C1-C18-alkyl, aryl, formyl, aliphatic or aromatic carbonyl, carbamoyl, sulphonyl, sulphoxyl, phosfonyl, sulphinyl or phosphinyl, or R1, - R6 are chosen among condensation products and addition products of acids, alcohols, phenoles, amines, aldehydes or epoxides.
Polybranched organic/ inorganic hybrid polymer and method for its manufacture. The hybrid polymer has the form of an inorganic core carrying organic branches. The core is first prepared by controlled hydrolysis and condensation of a silane with a structure: X-B- Si(-Y)3 in which X= NRl R2, while R1, R2 are chosen among hydrogen, alkyl and aryl, or R1, R2 are chosen among condensation products, addition products of one or more type of chemical substances such as acids, alcohols, phenols, amines, aldehydes or epoxides. B is a linkage group chosen among alkylene and arylene which may include oxygen, nitrogen, sulphur, phosphorous, silicon and boron. Y is chosen among hydrolyzable residues such as alkoxy, carboxyl, and halogen. The organic branches are developed by substituting N-H hydrogen atoms in the X-B group by reactions that are typical for primary and secondary amines, and/ or by adding an acid that causes an addition to the N atoms of the X-B group in the core. Specific uses of the hybrid polymers are also indicated.
