  • Patent number: 7707830
    Abstract: Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. In some embodiments of the invention, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, and a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient.

  • Patent number: 7662139
    Abstract: An apparatus for use in a fluid processing system having a pump. The apparatus includes a pump cassette for use with the pump. The pump cassette includes at least one pump chamber and a first port in selective fluid communication with the at least one pump chamber. A spiking assembly includes at least one hollow spike having a piercing end for piercing a first container. The at least one hollow spike includes a first spike in fluid communication with the first port of the pump cassette.

  • Patent number: 7632078
    Abstract: A plurality of pump cassettes are connected through distribution tubing to a single inlet tube such that the inlet tube is shared by the pump cassettes through the distribution tubing. The plurality of pump cassettes may be symmetrically attached to the distribution tubing. A four-port coupling may be inserted in the distribution tubing for making connection to the inlet tube and a middle one of the pump cassettes when the number of cassettes is an odd number.

  • Patent number: 7632080
    Abstract: A bezel and bezel assembly in which the bezel is a rigid block with a plurality of cavities. A depression in the block has ribs extending up therefrom to form an elevated contour. The depression includes at least one cavity therein for the application of air pressure into the depression and over the elevated contour. A gasket fits over the bezel so that positive pressure applied through the at least one cavity in the depression forces a gasket membrane to expand away from the pumping side and negative pressure applied through the at least one cavity in the depression pulls the gasket membrane against the elevated contour of the ribs. The bezel may include solvent bondable tubing connections for making pneumatic connections to the bezel.

  • Patent number: 7461968
    Abstract: A system, device, and method for mixing liquids involves pumping a first liquid into a first pump chamber of a pumping apparatus through a channel of the pumping apparatus and pumping a second liquid from a second pump chamber of the pumping apparatus into either the channel or the first pump chamber, preferably while the first liquid is being pumped into the first pump chamber, so that the two liquids are mixed within the pumping apparatus. The second liquid is preferably pumped in a pulsatile mode in which small quantities of the second liquid are pumped at intervals. The quantity and/or the interval can be dynamically adjusted to result in a predetermined concentration of the two liquids. The contents of the first pump chamber are pumped to a receptacle.

  • Publication number: 20080112258
    Abstract: A two-stage mixing system, apparatus, and method produces a solution including a first substance and a second substance in a predetermined ratio by first mixing the first substance with a first liquid to produce a first solution and then mixing the first solution with the second substance to produce a second solution. Multiple batches of second solution may be produced from a single batch of first solution. Multiple batches of second solution may be produced in parallel.

  • Publication number: 20080113331
    Abstract: A system, device, and method for mixing a substance with a liquid pumps the liquid into a container of the substance to produce a solution. The container may be part of a container assembly including a port assembly for coupling with the container to produce an inlet and/or and outlet port for the container. The container assembly may be received within a receiving chamber for causing the coupling. The solution may be permitted to flow out of the outlet port when the solution rises within the container to a level of the outlet port so that the substance is partially diluted before flowing out of the outlet port.
