    Abstract: A method of extracting an analyte from a sample is described. The sample is added to a sample container. A liquid solvent and a gas are added into the sample container. The addition of the gas is controlled to establish an elevated pressure within the sample container. The liquid solvent is heated to an elevated temperature that is below the boiling temperature of the liquid solvent at the elevated pressure. A type of gas is used that does not transition to a supercritical fluid at the elevated temperature and pressure used in the extraction process. The analyte can dissolve from the solid sample into the liquid solvent. Next, at least a portion of the liquid solvent containing the dissolved analyte can be removed from the sample container for subsequent analysis.

  • Patent number: 10017698
    Abstract: A single solvent method and machine for separating bitumen from oil sand ore are disclosed. The method includes the use of a single light paraffinic solvent, such as propane or butane as the agent to separate the bitumen from mined oil sand ore. Since light paraffinic solvents are vapors at atmospheric pressure and temperatures, the ore is placed in a pressurized container so that the solvent remains in a liquid state. When the container is pressurized, by the addition of the solvent itself, the liquid solvent is mixed with the ore to effect separation. The proposed machine settles more than 80% of the solids out under gravity in a modest period of time. The solvent-bitumen mixture is drained after the cleaning cycle, the container is depressured to a vapor recovery system and the remaining solids dumped out. The fine solids, drained with the liquids, are separated from the liquid mixture with relative ease by the use of current technology in other downstream equipment.

  • Patent number: 9834464
    Abstract: A recursive fractal system provides low cost, high throughput removal of contaminants, selected compounds, and elements from a flowable medium. This includes low energy desalination of saltwater, and removal contaminants from waste water. A series of concatenated, self-similar, co-axially aligned fractal stages are provided for defining a flow path for receiving the flowable medium, such as salt water. The configuration of self similar fractal stages as a succession of venturis recursively accelerates and separates flow vectors at each stage without the need for pumping. The series of venturis have been found to accelerate the water to such an extent that an electro hydrodynamic field interaction is magnified at each successive stage, such that contaminants, heavy metals, salt, or other selected compounds are aggregated by an electromagnetic field signature, separated and extracted from the flowable medium.

  • Patent number: 8893895
    Abstract: The fluidized bed processor of the present invention includes an internal filter assembly with a rack and a cartridge-type filter supported at the lower end by a bracket. The rack includes an elongated rod extending through the filter. An end cap is provided on the lower end of the rod for normal sealing engagement with the filter bracket. During normal operation of the processor, the upper and lower ends of the filter are sealed. During or after cleaning of the filter, the rack is lowered, and a spring separates the filter and support bracket from the end cap so as to create a gap for drainage of cleaning fluid.

  • Patent number: 8858794
    Abstract: A waste/sediment collecting container has a front vertical wall, a back vertical wall, two side vertical walls, and a sloped bottom surface. Along the lowest portion of the sloped floor surface lays a debris grate which allows water and pieces of sediment to pass through (but prevents larger pieces of waste from passing). The collection container includes a sump directly beneath the debris grate for collecting heavy sediment which passes through the grate. Sloped walls along the sides of the sump lead to U-traps on both sides of the container that allow liquid to pass through but prevent any solid waste from leaving the sump. Solid waste may be removed from the sump by removing the threaded service cap from the drain hole. Located beyond the traps are filter chambers having drain holes for inserting sediment filters which liquid passes through and exits the container.

  • Publication number: 20140262993
    Abstract: A sewer cleaning vehicle is disclosed. In one aspect, the sewer cleaning vehicle has a refuse storage tank having a first end with an opening. The sewer cleaning vehicle may also have a recycled water storage tank and a packaged liquid reclamation system for cleaning and transferring water from the refuse tank to the recycled water storage tank. In one embodiment, a hinged cover having a first side and a second side is pivotally mounted to the storage tank. The hinged cover can be movable between a first position in which the hinged cover covers the storage tank opening and a second position in which the storage tank opening is uncovered by the hinged cover. A transfer pump and a separator are supported by the hinged cover and are in fluid communication with the refuse tank through a port in the hinged cover.

  • Patent number: 8828222
    Abstract: A wearable or portable intermittently operable hydration system includes a purification module that contains one or more solid state light emitting devices that are positioned in the path of hydrating fluid, or water, flow through the hydration system to a mouthpiece. The light emitting devices illuminate a photocatalytic material disposed within the flow path in order to react and create fluid-purifying hydroxyls. The lights are instant on devices with essentially no ramp-up required, and a sensor or the opening of a push-pull valve controls the turning on of the lights. The fluid flow path may run from a bladder in a backpack worn by the user, a sports bottle worn by or carried by the user or may be through a water filtration system that a user operates via a pump. The power for the purification module may come from batteries, solar cells, fuel cells, or power converted from pumping, winding, etc.
