  • Patent number: 11199161
    Abstract: In accordance with the present invention, there are provided simplified systems and methods for catalytically deactivating, removing, or reducing the levels of reactive component(s) from the vapor phase of fuel storage tanks. The simple apparatus described herein can be utilized to replace complex OBIGGS systems on the market. Simply stated, in one embodiment of the invention, the vapor phase from the fuel tank is passed over a catalytic bed operated at appropriate temperatures to allow the reaction between free oxygen and the fuel vapor by oxidation of the fuel vapor, thus deactivating reactive component(s) in the gas phase.

  • Patent number: 10155180
    Abstract: In accordance with the present invention, there are provided systems and methods for contacting two or more fluids, useful, for example for purifying or infusing a fluid (by allowing efficient and/or uniform addition of components to or removal of components from the fluid). The components may be undesirable components to be removed from a fluid, or a desired component or components to be added to the fluid, for example, each of which is referred to herein as “component”. In this regard, the disclosed embodiments provide for the purification or infusion of a fluid by passing a liquid and a fluid through a contacting zone which facilitates intimate mixing of the liquid and the fluid. A differential of partial pressure, activity, fugacity or concentration of the components between the liquid and the fluid facilitates the transfer of the components between the liquid and the fluid in the intimately mixed liquid and fluid.

  • Patent number: 8540617
    Abstract: An extracorporeal pumping method includes receiving an inlet fluid into a compressible-expandable bladder sealably mounted within a housing and moving an actuating member mounted within a fluid chamber of a hydraulic actuating sub-assembly. A pressure transmissive fluid is displaced from the fluid chamber into the housing. The method includes compressing a volume of the bladder in the housing using the transmissive fluid displaced into the housing, the compressed bladder ejecting the inlet fluid from the bladder to provide an outlet fluid under pulsatile pressure. The actuating member is moved within the fluid chamber and the displaced transmissive fluid is returned from the housing into the fluid chamber. The method includes expanding the compressed bladder in the housing and receiving additional inlet fluid into the bladder. The movement of the actuating member is controlled such that the outlet fluid exhibits a predetermined pulse rate, stroke volume, and upstroke rise time.

  • Patent number: 8425396
    Abstract: A pulsatile blood circulating pump system for use in cardiopulmonary bypass, ventricular assist (LVAD, RVAD, BiVAD), ECMO, organ preservation, fetal cardiac bypass, cancer treatment, and areas of circulation research, which is controlled to produce blood flow that approximates physiological blood flow. The pump system includes a pulsating mechanism having a housing defining a chamber with a compressible-expandable bladder sealably mounted. A hydraulic actuator having a pressure imparting member that acts upon pressure transmissive fluid contained within the actuator chamber to generate a pulsatile pressure on the transmissive fluid, which results in pulsatile pressure being exerted on bladder to controllably vary the volume thereof. Additionally, the system includes a compact, motor that is associated with the hydraulic actuator for moving the pressure imparting member within the fluid chamber and further includes a fully programmable motion controller that controls the motor.
