  • Patent number: 11805996
    Abstract: A container (1) for in vitro diagnostic has a lower receptacle (2) designed to contain a non-toxic liquid (LS), an upper receptacle (3) designed to contain a toxic liquid (LF), and a connecting sleeve (4), in a threaded coupling with the lower receptacle (2) and the upper receptacle (3) for butt joining them. The connecting sleeve (4) has a transversal septum (40) being provided with a plurality of passage openings (48) and vent openings (49). When the container (1) is completely closed, both the lower receptacle (2) and the upper receptacle (3) abut the transversal septum (40). If the upper receptacle (3) is partially unscrewed with respect to the transversal septum (40), the toxic liquid (LF) flows by gravity into the lower receptacle (2). A method for storing a sample of human or animal tissue by using the container (1) is also provided.

  • Patent number: 11660555
    Abstract: A depth filtration device for the clarification of biological fluids including a composite depth filter media having a nonwoven first layer integral with a second layer containing a polyaeryionitrile (PAN) fibers, a filter aid, and a wet-strength resin. The depth filter media exhibits increased creased binding capacity for soluble impurities such as DNA and host eel! proteins from biological/cell culture feed-streams during secondary clarification and low-level impurity clearance of harvested cell culture fluids, such as those used for the manufacture of monoclonal antibodies. The depth filter media additionally exhibits significantly lower flushing requirements, resulting in lower levels of organic, inorganic and bioburden extractables released, high dirt holding capacities and good chemical and/or radiation resistance.

    Abstract: A portable fuel container configured to prevent liquid fuel contained therein from being entirely emptied from the container. The amount of liquid fuel retained in the container can be sufficient to maintain a fuel-to-air ratio in the container at a fuel-rich level that prevents combustion within the container if the container were to be placed near an ignition source or if an ignition source were to somehow enter the container. The container can also include other safety features such as, for example, a flash suppressor located at the fill opening, an extra wide fill opening, and/or an easily controllable dispensing spout. When a flash suppressor is employed, the perforations in the flash suppressor can be configured to retain fuel therein after fuel has been dispensed from the container and the flash suppressor is no longer submerged in fuel.

  • Patent number: 9955709
    Abstract: A method for washing fish flesh to remove water soluble sarcoplasmic proteins includes producing a mixture by combining wash water with fish flesh having sarcoplasmic and myofibrillar proteins, wherein the wash water removes some of the sarcoplasmic protein from the fish flesh; depositing the mixture on a screen separator. The wash water having sarcoplasmic proteins is separated from the mixture while a speed of the screen separator and a speed of the mixture at the interface with the screen separator remains about equal and reducing or eliminating shear forces at the interface between the screen separator and the fish flesh. Thus, washed fish flesh fish flesh with an increase in a percent of myofibrillar protein retained in the fish flesh is produced.

The second stage can also be coconut derived activated carbon mixed with citricidal, and used to remove bacteria. Contaminated water traverses from the first stage to the second via gravity flow, resulting in water that is free of heavy metals and bacteria.

  • Patent number: 8590711
    Abstract: The invention relates to a method of diagnosing the operation of a water purification installation of the filter medium device type, the material of the filter medium being made up of particles, the method including the following steps: a characterization step of characterizing at least one physical and/or mechanical parameter of the filter medium device to establish a permeability value Ks (expressed in m/s); a comparison step of comparing said established permeability value Ks with a predetermined range [kmin; kmax] of permeability values representing a satisfactory operating state of the purification installation; and a diagnosis step during which the filter medium device is assigned an operation indicator according to the result of the comparison step. Applications include non-collective sanitation (NCS) systems and stand-alone sanitation systems.

  • Patent number: 8545705
    Abstract: One exemplary embodiment can be an apparatus for isomerizing a hydrocarbon stream rich in a C4 hydrocarbon and/or at least one of a C5 and C6 hydrocarbon. The apparatus can include:a vessel containing a fluid including at least one reactant; a fluid transfer device receiving the fluid including at least one reactant from the vessel; at least one drier receiving the fluid including at least one reactant from the fluid transfer device; and a reactor communicating with the at least one drier to receive the fluid including at least one reactant. In addition, the at least one drier may communicate with the vessel at least by sending the fluid including at least one reactant or the regenerant through a fluid tapering device for at least one of regulating the flow and reducing the pressure of the regenerant to the vessel.

  • Patent number: 8524080
    Abstract: An apparatus for removing cyanotoxins and excess ions from contaminated water. Contaminated water passes from a storage tank (200), through a sand filter (210), through a reaction chamber (230), and finally through a carbon filter (270). The sand filter removes particulates and some bacteria. Treatment of the water in the reaction chamber first destroys cyanotoxins, algae, and bacteria through the use of high voltage shocks applied between two groups of electrodes (285, 285?), then the voltage on the electrodes is lowered and electrolysis is used to sequester free ions in the water in the region near the electrodes. Partially treated water is removed from the upper portion of the reaction chamber and passed through a carbon filter (270) to remove radiation, and to improve taste and smell. After passage through the carbon filter, the water is potable. The water remaining in the reaction chamber is discarded into a reservoir (265).
