Abstract: The present invention relates to the use of surfaces that exhibit different surface energies wherein the difference in surface energies is configured to disrupt capillary laminar flow of a fluid travelling between the two surfaces. The invention further relates to the use of such surfaces in assay methods including a device utilising same.

Abstract: The present invention relates to the use of amphipathic polymers to enhance lateral flow and reagent mixing on assay devices. More specifically, the invention relates to use of an amphipathic polymer in assay methods including a device for determining the concentration of lipids in blood serum or plasma.

Abstract: A brazing furnace includes a housing defining an interior environment having an inlet and an outlet, a plurality of heating elements mounted within the housing and adapted to heat the interior environment to an elevated temperature, and a conveyor belt extending through the housing and supported on a plurality of driven rollers whereby an object placed upon the conveyor belt at the inlet is transported through the inlet into the interior environment and out through the outlet. The conveyor belt includes a plurality of interconnected metal links and a thermal barrier coating applied to the metal links, thereby insulating the metal links and restricting the amount of thermal energy that is absorbed by the conveyor belt as the conveyor belt moves through the interior environment.

Abstract: A roof angle attachment device (10) attachable to a vertical stud (14). The roof angle attachment device (10) having a left mount (12L) which has a left mount clip (12LA) positioned along a top distal edge functioning to hold a roof angle (16) to support exterior framing (18). The roof angle attachment device (10) further has a right mount (12R) securely attached along a left distal edge to a right distal edge of the left mount (12L). The right mount (12R) further comprises at least one right mount opening (12RA) wherein a fastener is positioned therethrough to securely attach the right mount (12R) to the vertical stud (14).

Abstract: Novel vectors are disclosed for use in filamentous fungi such as Aspergillus sp. in particular, whereby protein coding regions may be inserted therein to achieve expression or expression followed by secretion of the coded protein from the host. Signal peptide sequences and promoter sequences valuable for this purpose are disclosed as are expression vectors containing coding regions native or foreign to the fungal host. In accordance with the invention, a filamentous fungus such as Aspergillus may be provided with foreign or natural coding regions associated with foreign or natural promoter sequences and optionally signal peptide sequences which can be used to control the expression and/or secretion of the proteins encoded by these coding regions.

Abstract: A valve assembly for an energy transfer unit comprises a source of hydraulic fluid, a reciprocating valve member reciprocable from an open position to a closed position, a slidable sleeve assembly whereby the hydraulic fluid is selectively allowed to force the valve member into the open position or into the closed position, and a solenoid, for selectively operating the slidable valve assembly to provide for the open or closed position. The slidable sleeve assembly comprises a first sleeve half portion and a second half portion, each sleeve half portion having at least one fluid-passing aperture defined therein. Two chambers are provided, an upper chamber and a lower chamber, for selectively receiving pressurized fluid therein. Whether the valve member is in the closed position or in its open position depends upon whether or not fluid is entering or exiting the respective upper chamber and lower chamber.
