  • Patent number: 8411930
    Abstract: A system and a method for detecting a damaged or missing machine part. The system includes an image capturing device for capturing images of the machine and a processor for processing the captured images. The system may further include a sensible output for providing an indication of a damaged or missing machine part. The method includes capturing images of the machine against a background which moves relative to the machine over time, selecting a pair of time-separated images from the captured images, generating a displacement image from the pair of images, comparing the machine from the displacement image with a machine model, and identifying a damaged or missing machine part from the comparison of the displacement image with the machine model. The method may further include providing a sensible output which indicates a damaged or missing machine part.

  • Patent number: 8063269
    Abstract: The present invention provides transgenic plants with reduced levels of saturated fatty acids in the seed oil and methods of making these plants. The transgenic plants developed through this method contain reduced levels of saturated fatty acids in seed oil due to expression of a prokaryotic delta-9 desaturase enzyme (i.e. an enzyme that introduces cis double bonds at the delta-9 position of saturated fatty acids) operably linked with an endoplasmic reticulum retention and retrieval signal sequence. One example of the invention is a plant expressing a heterologous delta-9 desaturase enzyme from cyanobacterium Anacystis nidulans, which converts lipid-bound 16:0 and 18:0 fatty acids into corresponding 16:1 and 18:1, in operative linkage with a KKSS (SEQ ID NO:5) endoplasmic reticulum retention and retrieval signal sequence.

  • Patent number: 8016039
    Abstract: A method of reducing water influx into a wellbore, wherein the wellbore is in fluid communication with a subterranean formation such as a gas producing formation or gas reservoir. The method particularly places a gelant in a desired position down the wellbore and into the formation in order to thereby reduce the influx of water and enhance the resulting gas production. The method includes the steps of first introducing a gelant into the wellbore and second introducing a temporarily stable foam into the wellbore in order to overdisplace the gelant from the wellbore and into the formation.

  • Patent number: 7811343
    Abstract: A method and apparatus for separating liquid droplets from a gas stream. The method includes the steps of conditioning the gas stream which contains the droplets so that the gas stream exhibits substantially turbulent flow, passing the gas stream generally axially through a flowpath so that the gas stream is in communication with a collector surface, collecting the droplets on the collector surface, and draining the collector surface to remove the collected droplets from the collector surface. The apparatus includes a flowpath, a collector surface for collecting the droplets, a flow conditioner for conditioning the gas stream, and a drainage mechanism for draining the collected droplets from the collector surface.

  • Publication number: 20100252181
    Abstract: A board suitable for use as container flooring uses bamboo and fast-growth low-density wood. Thin layers of high-density bamboo composites are used to overlay on surfaces of a core layer which can be the composite of wood veneer and wood strand-based composite, or wood veneer and bamboo stripe sheet composite. This invention combines the benefits of bamboo and wood materials to produce a bamboo-wood composite board having sufficient mechanical and physical strength and durability for use as container flooring.

  • Patent number: 7736772
    Abstract: This invention relates to a stack comprising a continuous solid-phase matrix and tubular fuel cells embedded in the matrix. Each fuel cell comprises an inner electrode layer, an outer electrode layer, and an electrolyte layer sandwiched between the inner and outer electrode layers. The matrix is sufficiently porous to allow a first reactant to flow through the matrix and to the outer electrode of each fuel cell, and have sufficient mechanical strength to support the fuel cells in the stack. The fuel cells are embedded such that a second reactant may be flowed through the inside of each tubular fuel cell and to the inner electrode thereof. Alternatively, a stack of tubular separation membranes or a stack of tubular membrane reactors may be embedded in the matrix. The matrix material may comprise solid state foam, metal filament, or metal, cermet, or ceramic wool.

  • Patent number: 7663757
    Abstract: A method for obtaining a reflectance property indication of a sample which includes making a reflectance measurement of the sample and correcting the reflectance measurement in order to obtain the reflectance property indication. The reflectance measurement represents an observed reflectance of the sample, the reflectance property indication represents a standardized reflectance of the sample, and correcting the reflectance measurement accounts for a difference between the standardized reflectance and the observed reflectance. An apparatus for making a reflectance measurement of a sample which includes a housing defining a viewing port, a temperature control mechanism for controlling the temperature within the interior of the housing, and an optical reflectometer contained within the interior of the housing. The reflectometer has a measurement direction and is movable within the housing so that the measurement direction can be selectively aligned with the viewing port.
