  • Patent number: 6874355
    Abstract: A method and device for monitoring and controlling a pharmaceutical, chemical or food process, in which the biological activity and/or the bio-mass of micro-organisms in the process is monitored, and in which the state of the process is detected by monitoring viscosity and/or aggregate size and/or content of a dispersion of proteins, crystalline particles or fat droplets that are processed, respectively. The micro-organisms and/or bio-molecules produced in the process, and the proteins, crystals particles or fat droplets being processed are monitored by means of acoustic spectroscopy.

  • Patent number: 6245426
    Abstract: An electric device comprising a conductor and a porous conductor insulation impregnated with a dielectric fluid. Where the dielectric fluid comprises; a polymer; and a hydrocarbon-based fluid. The dielectric fluid being composed such that a part of the polymer molecule interacts with the hydrocarbon based fluid or another part in the polymer molecule in such a way that the dielectric fluid; at temperatures within a first low temperature range is in a highly viscous and elastic, essentially gelled, state; at elevated temperatures within a second higher temperature range, is in low viscosity easy flowing and essentially newtonian state; and that the viscosity of the dielectric fluid is, over a third limited temperature range, the transition range, changed between the low viscosity state and the highly viscous state. The transition range comprises temperatures between the first and the second temperature ranges.

  • Patent number: 5483562
    Abstract: The invention relates to a volume delimitation tank (1) for preventing or limiting contamination of the surrounding liquid medium when working with contaminated parts. The volume delimitation tank (1) comprises a sack or channel which constitutes at least the substantially vertical walls (1a-d) of the tank and is made of a material which is capable of being folded, which is radiation-resistant, and resistant to puncture. The walls (1a-d) can be provided with fold notches (27) to obtain a well-defined folding when, for example, lowering at least one wall portion (1a-d) for passing objects out of the tank (1). The walls (1a-d) of the tank (1) are arranged at a bottom part (9). Cleaning equipment (16) is arranged inside the tank (1) for continuous cleaning of the contained volume.
