Abstract: An applicator mixes an additive with a fluid stream and dispenses the resultant mixture. The applicator includes a housing having a fluid inlet, a downstream auger chamber, a downstream mixing chamber, and a flow path fluidly connecting the fluid inlet to the mixing chamber. A turbine auger assembly including an auger and a rotor is rotatably connected to the housing to move the additive towards the mixing chamber, help mix the additive with the fluid stream, and then disperse the mixture to the auger chamber, which includes a hopper port and a downstream auger chamber exit exposed to the mixing chamber. The turbine auger assembly is rotatably connected to the housing.

Abstract: The present invention provides a pump system comprising a bearing housing coupled to a pump liner, the pump liner defining a fluid conduit, the pump liner comprising a fluid inlet and a fluid outlet; and at least one rotor having a first rotor portion and a second rotor portion, the first rotor portion being disposed within the fluid conduit and the second rotor portion being disposed within the bearing housing; the first rotor portion comprising a first conveying stage adjacent to the bearing housing, and a second conveying stage adjacent to the first conveying stage, the first and second conveying stages being configured to convey a fluid, the first conveying stage being configured to convey the fluid from the bearing housing into the fluid conduit. The new pump systems rely on a dynamic restriction to reduce the need for mechanical seals between bearing housings and raw process fluid.

Abstract: A protective shield for a device exposed to heat includes a granular fill layer, a nano particle layer, a metallic foam layer, a thermal barrier coating, or combinations thereof. The shield is configured for providing thermal resistance, and damping of vibrations, and acoustics to the device.

Abstract: The invention provides methods and compositions for the efficient expression and isolation of BACE2 polypeptides from inclusion bodies and its refolding to an active enzyme.

Abstract: An instrument for observing and measuring string segment angles in pianos wherein strings exist in three segments, a speaking string segment, a bridge string segment, and a rear string segment, these three segments creating two angles in the approximate vertical plane, a speaking string segment - bridge string segment angle, and a bridge string segment - rear string segment angle. Subject instrument having the capacity to measure said string segment angles accurately, and directly, without the need for calculations.

Abstract: Pianos in which the desired downbearing force of the strings upon the bridges and soundboard is predetermined and accurately simulated upon the soundboard bridges so that adjustments can be made to the bridge-string plate relationship so that the previously simulated force will be exerted upon the soundboard and bridges when the piano is fully strung and at pitch.
