  • Water permeable membranes and methods of making water permeable membranes
    Patent number: 8196754
    Abstract: Water permeable membranes and methods of forming water permeable membranes are provided. The water permeable membranes are comprised of a cross-linked polyamide containing at least one bifunctional additive that is hydrophilic and reactive. Additionally, in accordance with other embodiments of this invention, methods of forming water permeable membranes comprised of a cross-linked polyamide containing at least one bifunctional additive that is hydrophilic and reactive are provided. Specifically, the water permeable membranes may comprise a membrane formed from a cross-linked aromatic or aromatic/aliphatic polyamide interfacially polymerized on a porous support. The presence of the at least one hydrophilic and reactive additive improves the flux and salt retention properties of the membrane in comparison to a membrane formed without the at least one hydrophilic and reactive additive.

  • Micro-channel tubes and apparatus and method for forming micro-channel tubes
    Patent number: 8191393
    Abstract: An apparatus and method are provided for extruding a micro-channel tube (402) from a non-aluminum metal or alloy such as copper. The micro-channel tube is formed by simultaneously extruding two rectangular shaped billets (404; 406) to form a top portion of the micro-channel tube and a bottom portion of the micro-channel tube in parallel. The top and bottom portions are then joined during the extrusion process (e.g., within a die assembly) to form the micro-channel tube (402).

  • Methods for quantifying microRNA precursors
    Patent number: 8192938
    Abstract: The present invention is directed to methods, reagents, kits and compositions for detecting microRNA (miRNA) precursors in a biological sample. The methods uses gene-specific primers and reverse transciptase to convert the primary miRNA precursors (pri-miRNA) and pre-miRNA precursors (pre-miRNAs) to cDNA. The method also uses amplification reactions using gene specific forward and reverse primers that are targeted to the hairpin sequence of pri- and pre-microRNA precursors to detect the expression levels of both the pri- and the pre-microRNAs.

  • Method of assembling a ball valve
    Patent number: 8186371
    Abstract: A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.

  • Modular test systems for severe environments
    Patent number: 8184437
    Abstract: A modular equipment testing apparatus is suitable for use in severe environments. The testing apparatus comprises a base computing unit, an interchangeable test instrument board, and an interchangeable equipment interface pod. The base computing unit and the interchangeable test instrument board are sealed within a computing case. A bottom panel of the computing case is formed of a heat conducting material and acts as a heat sink for removing heat from inside the computing case. The computing case and the equipment interface pod interface to form a hermetically sealed case, which can withstand a drop of 1 meter to a solid surface and immersion to a depth of 0.5 meters in water without damage to components located within the sealed case.

  • Reduced alloy bushing flange
    Patent number: 8171754
    Abstract: A cooling bushing flange having a reduced amount of precious metal is provided for a glass fiber production apparatus. The flange includes a first portion formed of a precious metal or a precious metal alloy extending outwardly from a bushing and a second portion formed of a non-precious metal. The non-precious metal portion of the flange may be affixed to the precious metal portion by known metal bonding methods. A cooling tube is positioned on the non-precious metal portion to create a thermal seal and prevent molten glass from leaking from the interface of the bushing block and bushing. The precious metal portion of the inventive flange is a fraction of the size of precious metal present in conventional bushing flanges. By reducing the amount of precious metal incorporated in the flange, a significant reduction in the overall cost of the bushing and in the manufacture of glass fibers can be obtained.

  • Diaphragm foam pump
    Patent number: 8172555
    Abstract: A foam pump including a diaphragm made of a flexible material defining a mixing chamber and having an inlet and an outlet. An inlet passageway, having a one-way valve therein, is in fluid communication with a reservoir containing a foamable liquid and the inlet. The inlet passageway includes an air inlet and associated one-way valve. The pump includes an outlet passageway, having a one-way valve therein, in fluid communication with the outlet. The foam pump includes an electric motor. that drives a motor driven element to collapse and expand the diaphragm. Expansion of the diaphragm creates a vacuum causing foamable liquid and air to flow into the mixing chamber. Collapsing of the diaphragm causes the liquid and air mixture to be forced out as foam.
