  • Patent number: 11352651
    Abstract: The invention relates to the isolation of polyunsaturated fatty acids (PUFAs) from a lipids containing biomass. The main characteristics of the method are that a suspension of cells containing PUFAs is obtained and the cells are optionally lysed. The suspension is concentrated and then incubated for at least an hour at a controlled temperature while adding a specific range of base equivalents to biomass and maintaining a moderate pH. The isolation of lipid may be performed in the absence of organic solvents and without the addition of salt.

  • Publication number: 20120190518
    Abstract: A method for manufacturing a roll. The method includes positioning a shaft for the roll within a mold, introducing flowable material into the mold from a first end thereof, rotating the shaft at least about 20 revolutions, and following introducing the flowable material into the mold and rotating the shaft, curing the material at an elevated temperature. The method substantially reduces or otherwise eliminates weld lines and flow lines in the manufactured roll.

  • Patent number: 7658876
    Abstract: The present disclosure relates to a process for making a seamless tube from a liquid. A mandrel may be provided having a longitudinal axis, an outer surface and a length. A liquid material may be applied to the outer surface of the mandrel by one or more doctor blades, spaced apart from the mandrel outer surface and inclined at an angle ? with respect to the mandrel longitudinal axis, which may be moved along the longitudinal axis of the mandrel while rotating the mandrel around its longitudinal axis. One or a plurality of fingers may overly the mandrel and be positioned upstream of the one or more of blades, relative to the direction of movement of the blades along the longitudinal axis of the mandrel. The liquid material may then be converted to form a seamless tube.
