  • Patent number: 9827563
    Abstract: Fluidic systems and methods for analyses are provided. In some embodiments, systems and methods for improved measurement of absorbance/transmission through fluidic systems are described. Specifically, in one set of embodiments, optical elements are fabricated on one side of a transparent fluidic device opposite a series of fluidic channels. The optical elements may guide incident light passing through the device such that most of the light is dispersed away from specific areas of the device, such as intervening portions between the fluidic channels. By decreasing the amount of light incident upon these intervening portions, the amount of noise in the detection signal can be decreased when using certain optical detection systems.

  • Patent number: 8366917
    Abstract: A method of recovering minerals from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be contacted with an agent sufficient to remove minerals therefrom. The agent is typically a solution containing a solvent, leachant, chelating agent and the like via which minerals can be removed having value, toxic minerals, radioactive minerals and the like.

  • Publication number: 20120298579
    Abstract: An apparatus for separating hydrophilic material from hydrophobic material, comprising: (a) a body having a first and second parallel walls defining an elongated cavity; (b) a water-absorbing material in the cavity along the first wall and having a surface essentially parallel to the second wall, thereby defining a channel between the surface and the second wall; (c) a first inlet having a first inlet end disposed in the channel, the first inlet being configured for injecting a mixture of hydrophilic and hydrophobic material; (d) a first outlet having a first outlet end disposed in the channel proximate the surface downstream of the first inlet end and configured for removing the hydrophilic material; and (e) a second outlet having a second outlet end disposed in the channel a distance from the surface downstream of the first inlet end and configured for removing the hydrophobic material.

  • Patent number: 8318077
    Abstract: Methods of producing collection tubes are presented. The methods include providing a separator substance that can rapidly polymerize in a short time to a desired hardness and disposing the separator substance within the lumen of the tube. The separator substance is formulated to have a density between an average density of a serum fraction of whole blood and a cell-containing fraction of whole blood, and to be flowable with whole blood. Upon centrifugation of a tube having blood, the separator substance forms a barrier between the whole blood fractions. The barrier rapidly hardens forming a solid barrier when triggered by a suitable energy source.

  • Patent number: 8298412
    Abstract: A cross-corrugated structure packing module is provided for use in mass transfer or heat exchange columns and has particular applicability in severe service applications in which fouling, coking, and erosion are of concern. The structured packing module has a plurality of upright, parallel-extending, corrugated plates. Spacer elements are used to maintain the corrugations of adjacent plates in spaced apart relationship to reduce the opportunity for solids to accumulate on the surfaces of the plates. The plates are also free of apertures or surface treatments that would increase the opportunity for solids to accumulate on the plates.

  • Patent number: 8282540
    Abstract: Methods for using a centrifuge are presented. A vessel containing a sample and a separator substance is placed within a centrifuge. Upon sufficient centrifugation, the sample separates into two or more fractions separated by the separator substance. The centrifuge exposes the separator substance to a sufficient energy to polymerize the separator substance to produce a hardened barrier between the fractions.

  • Patent number: 8257593
    Abstract: A device, system and method for exchanging components between first and second fluids by direct contact in a microfluidic channel. The fluids flow as thin layers in the channel. One of the fluids is passed through a filter upon exiting the channel and is recycled through a secondary processor which changes the fluid's properties. The recycled fluid is reused for further exchange. The filter excludes blood cells from the recycled fluid and prevents or limits clogging of the filter. The secondary processor removes metabolic waste and water by diafiltration.

  • Patent number: 8187861
    Abstract: For extracting phosphorous from algae-in a body of water, the algae are deposited into a sealable tank (200) that is then evacuated, thereby rupturing the algal cell walls. The ruptured algae are then moved to a second tank (260), mixed with water and bacterial cultures, and allowed to settle until the lipids rise to the top and the oil-less debris settles to the bottom. The second tank also contains sacrificial (295) and rusted electrodes (320). The phosphorous from the algae combines with the rust. The lipids and debris are then removed. Next, an electrical source (315) causes the rust to be removed from the rusted electrodes and settle. In addition, a phosphorous-rich scum floats to the top. These components are placed in storage containers for later use and the water is returned, thereby reducing its phosphorous content.

  • Publication number: 20120125836
    Abstract: An apparatus may include a separator and/or a discharger. A separator may include a separator channel, an influent portion configured to allow the passage of a first fluid into a separator channel, an effluent portion disposed above an influent portion and/or a fluid-lift portion between an influent portion and an effluent portion. A discharger may be disposed below a fluid-lift portion and/or may include a portion external to a separator channel, which may include a downward angle relative to an effluent portion and/or may be configured to minimize the passage of a second fluid into a discharger as the second fluid buoyantly travels in a separator channel from an influent portion to an effluent portion. A second fluid may have a density that is less than the density of a first and/or may be configured to lift a first fluid to a fluid-lift portion.
