  • Patent number: 10035946
    Abstract: Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked via hydrolyzable crosslinking moieties derived from a multifunctional hydrazide, a multifunctional amine, a multifunctional hydroxylamine, or a combination thereof and have improved injectivity into the well; the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

  • Publication number: 20170158522
    Abstract: Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

  • Patent number: 9618733
    Abstract: An imaging assembly for the viewing, imaging, and analysis of chemiluminescent or bioluminescent samples in gels or other substrates, in which an adjustable camera and lens module having a prime or fixed lens or a focusing lens is moved to change the field of view by shifting the focal plane of the camera and lens module. The imaging assembly can also include a mirror to bend or fold the optical path between the camera and lens module and the target area having a sample, in which the mirror can move in the same vertical direction as the camera and lens module. Further, the camera and lens module can be configured to more move in a diagonal direction relative to the location of the imaging target area. The imaging assembly can further have a duct system adaptable to adjust with the movement of the camera and lens module.

  • Patent number: 9606111
    Abstract: Disclosed herein are methods of protein quantification and normalization using haloalkylated tryptophan fluorescence. Complex protein samples, i.e., samples that each contain 1,000 or more distinct proteins, from diverse sources that do not have common protein profiles are treated with a halo-substituted organic compound (i.e. haloalkane) that reacts with tryptophan residues to form fluorescent products. Irradiation of the samples with ultraviolet light and the detection and quantification of the resultant fluorescent emissions from all proteins in each sample are then used to obtain comparative values for total protein content among the various samples.

  • Publication number: 20160191196
    Abstract: An optical signal module including a driver and an optical signal module. The driver includes a differential pair configured to receive and process an input signal to create a drive signal. A modulation current source provides a modulation current to the differential pair. One or more termination resistors connected to the differential pair for impedance matching. A first switch, responsive to a first control signal, maintains charge on a charge storage device. The optical signal module includes an optical signal generator arranged between a supply voltage node and a bias current node. The optical signal generator receives the drive signal and generates an optical signal representing the input signal. A second switch is between a supply voltage node the bias current node. The second switch, responsive to second control signal, selectively establishes a short between the supply voltage node the bias current node.

  • Patent number: 9058648
    Abstract: An image system for detecting chemiluminescence in a sample uses a highly binned, short exposure initial image to calculate the exposure time for a final image of the sample. After calculation of the exposure time, at least two final images are taken, with saturated pixels removed and replaced in a first image with corresponding unsaturated pixels from a second image. The corresponding pixels are adjusted to reflect the different intensity levels between the first and second images, and the first image becomes the final image reflecting the detected chemiluminescence.

  • Patent number: 8913127
    Abstract: Methods, apparatuses, and systems for imaging biological/chemical samples are provided. A calibrated imaging system can allow a user to obtain an optimal focus setting (position) for any effective distance (e.g. a zoom setting). The optimal focus can be determined from a functional approximation that defines a relationship between effective distance and focus setting. A user can input a size, and an imaging system can determine the appropriate effective distance and focus. An imaging system can also determine a size based on any effective distance. A flat-field correction can also be determined for any effective distance or size.
