Abstract: A duct adapter system directs air flow relative to a hybrid water heater. The duct adapter system includes a collar adapted to surround a vent of a hybrid water shroud. The collar couples to standard duct pipe to extend ductwork to a heat pump portion of the hybrid water heater. A boost fan may be included in the system for boosting air flow to or from a remote location. The duct adapter system is adapted to deliver a warm air supply to the heat pump from the remote location, or deliver the cool discharge air from the heat pump water heater to a remote location.

Abstract: Hydrophobic ion pairing (HIP) is applied to solubilize proteins and/or adjuvants in an organic medium. A polymer is cosolubilized in the medium and microspheres encapsulating the protein and/or adjuvant can be produced by a single emulsion method. Microspheres prepared by this method exhibit low initial burst of the protein and gradual release over time, and elicit a strong and comprehensive immune response. Compositions comprising a protein and an adjuvant co-encapsulated in microspheres are provided.

Abstract: A reversible turbine pump includes a pair of end walls and a side wall defining an annular pumping chamber. A turbine impeller mounted for reversible rotation in the chamber includes a rigid input shaft. One end of the shaft extends through one end wall and is sealed from the chamber. A spring biases the other end of the shaft toward the other end wall. Cooperating thrust bearing members, mounted to the other end of the shaft and the other end wall, provide a large planar area of low friction engagement therebetween. The pumping chamber has a pair of inlets, a pair of outlets and a dam. The first inlet and second outlet are on one side of the dam while the second inlet and first outlet are on the other side of the dam so that reverse rotation of the impeller pumps fluid in opposite directions through a different set of inlet and outlet. Valves associated with the inlets and outlets permit fluid flow in the desired direction and prevent fluid flow in the opposite direction.

Abstract: A temperature sensor assembly for an automatic solid disk surface unit includes a temperature sensor enclosed in a metallic hermetically sealed generally cylindrical housing. Upper and lower centrally apertured annular disks formed of a porcelain ceramic material thermally isolate the sensor housing from the surrounding surface unit. A protective metallic skirt conforming to the outer contour of the insulating disks holds the assembly together. A layer of glaze material covers the exposed upper surface of the upper disk in the gap between the skirt and the housing to prevent the absorption of food soils.
