  • Patent number: 8021630
    Abstract: An anticoagulant-coated dipstick is selectively receivable by the central fill port of a rotor of a blood centrifuge. The dipstick includes an elongated, rod-like member having a first axial end and an opposite second axial end, and a cap affixed to the second axial end. At least a portion of a surface of the rod-like member is coated with an anticoagulant. The elongated rod-like member of the dipstick is dimensioned in length and diameter to be receivable through the central fill port of the rotor to contact a blood sample contained therein. The cap is circular in shape, with a diameter that is greater than that of the rotor fill port to entirely cover and seal the fill port to prevent leakage therethrough of a blood sample contained in the rotor, especially when the rotor is gently agitated or inverted.

  • Publication number: 20100155331
    Abstract: An energy-efficient process for dewatering an aqueous organic solution includes using freely available solar energy to concentrate a draw solution within a reservoir. The draw solution is used in conjunction with a membrane to remove water from the organic solution in a forward osmosis process. The draw solution is diluted by the osmosis process, and returned to the reservoir to be re-concentrated and reused in the osmosis process.

  • Publication number: 20100155329
    Abstract: A process for purification of fluids, for example, desalination of seawater or brackish water, using organic solutes in a concentrated water solution for use in a forward osmosis process, to extract fresh water out of salt water through the forward osmosis membrane, and subsequently separating the organic solutes out of the diluted forward osmosis permeate by cloud point extraction, thereby regenerating a concentrated organic solution for recycling to the forward osmosis process, and fresh water for potable water use.

  • Patent number: 7713425
    Abstract: An oil management system and oil filter utilized in association with an internal combustion engine. The oil filter comprises high-efficiency filtration media for filtering engine oil associated with the internal combustion engine. At least one type of time release additive can be impregnated into the filtration media, wherein the time release additives are automatically released into the engine oil filter from filtration media in order to replenish additives already present in the engine oil. Additionally, a sensor module can be provided that monitors oil quality and oil filter efficiency through detecting one or more attributes of the engine oil filtered through the filtration media of oil filter in order to efficiently conserve and manage the oil and reduce the interval of oil changes thereof by extending the life of the engine oil through the replenishment of the additives present in the engine oil and higher filtration effectiveness of the filter.

    Abstract: Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient. Cellular blood components are removed from the whole blood by hemofiltration, to provide filtered plasma comprising metabolic waste that is substantially reduced of blood cells. The cellular blood components may be returned to the patient. The filtered plasma comprising waste may be removed from the blood processing apparatus through a waste path for further processing in a separate apparatus, or in the same apparatus in a second stage processing procedure to remove metabolic waste components and excess water from the plasma by hemodialysis. At least one of the hemofiltration and hemodialysis processing apparatus comprises a Taylor vortex-enhanced separation apparatus.

    Abstract: A method and apparatus is disclosed for separating a slurry into liquids and solids in a pressure filter apparatus and for forming a substantially dry and often loosely packet filter solids cake wherein a high temperature and high pressure steam is introduced into an initially formed filter cake in the pressurized filter apparatus to force the steam into the interstices of the formed filter cake and then pressure within the filter apparatus is reduced to permit the steam to flash and to expand within the interstices to absorb any remaining fluids within the formed filter cake and to cause the filter cake to become substantially dry and loosely packed. The filtered solids cake is then discharged from the filter apparatus.
