  • Patent number: 11433396
    Abstract: In a polymer assay cartridge having wells containing reagents, beads and sample, where the wells are covered (e.g., with Parafilm® or films) and shipped to the point of care, the reagents and well contents can leak out. The reagent solutions are made semi-solid by adding hydrogel reagents and cooling to form a gel. Preferably, the hydrogel is heated before an assay is conducted with the cartridge, and pigmented beads in the wells indicate melting or excessive heating, or congealing of the hydrogel, based on pigment color change.

  • Patent number: 11433401
    Abstract: A purification system and method may include a container receiving portion, pump, and magnetic field generating element. The container receiving portion may be configured to receive and support a container containing a mixture. Magnetic beads may be added to the container for separating a target substance from a remainder of the mixture. The magnetic field generating element may be movable relative to the container receiving portion between a non-working position remote from the container receiving portion and a working position adjacent an outer periphery of the container receiving portion. In the working position, the magnetic field generating element may attract the magnetic beads and hold them firmly against an interior surface of the container. While the magnetic beads are immobilized by the magnetic field generating element, the pump may remove the mixture from the container, leaving behind the magnetic beads bound tightly but reversibly to the target substance.

  • Patent number: 9956563
    Abstract: A process for separating clean water which has an impurities content of less than 100 ppm from waste materials such as farm manure is disclosed. In a first step, a plate separator splits the waste material stream into a first effluent fraction and a first solids fraction. The first solids fraction then undergoes two stages of pressing to increase the solids contents to about 30 to 40 percent which makes it suitable for granulation or pelletizing. The first effluent fraction is treated in successive stages with various chemical agents resulting in the removal of most of the solids and inorganic impurities from the effluent to achieve drinkable water purity.

  • Patent number: 9795708
    Abstract: A method of cutting metallic foams that eliminates the problem of smeared surfaces is provided. The method involves infiltration of the foam with another material to serve as a support structure to the foam when being cut. The method can be executed using softer polymeric materials such as waxes, which are then frozen for machining. These materials are subsequently heated and removed from the foam. In a similar manner, epoxy material can be used, which requires no freezing. In this method, the epoxy material is burnt from the foam upon completion of machining. The method allows for machining foams using conventional machining processes, rather than non traditional methods such as electrical discharge machining.

  • Patent number: 9752989
    Abstract: A sample analyzing method for suppressing an adverse effect on detection accuracy of a detection target substance is disclosed. In the sample analyzing method, a magnetic particle as a support of a detection target substance is transported by magnetic force to a second liquid container through a passage between a first liquid container storing a first liquid containing the magnetic particle and the second liquid container storing a second liquid containing a labeled substance to forma complex with the detection target substance and the magnetic particle. The complex formed in the second liquid container and containing the detection target substance, magnetic particle, and labeled substance is transported to a third liquid in a flow path, and the magnetic particle is transported to a detection tank for detecting the detection target substance, while being agitated in a mixed liquid of the complex and third liquid within the flow path.
