摘要： A pipeline isolating device for istallation into and occlusion of a pressurised liquid or fluid supply pipe comprising a substantially solid and deformable boot (1) wich is adapted to move between an expanded and an unexpanded state and a shaped plunger (2) adapted to move into and out of said boot (1) wherein the boot (1) has a hollow interior (3) with a displacement contour (6) adapted to receive and cooperate with said plunger (2) so as to cause said boot (1) to move between said expanded state when the plunger (2) is inserted into said hollow interior (3) of the boot (1) and said unexpanded state when said plunger (2) is withdrawn from the interior (3) of the boot (1).

摘要： A water heating system includes a burner assembly for providing a source of thermal energy to a heat exchanger. A water inlet conduit is coupled to the heat exchanger assembly for supplying fresh water to be heated, and a water exit conduit is coupled to the heat exchanger assembly for delivering the heated water to a point of use. A bypass conduit connects the water exit conduit to the water inlet conduit, and a pump disposed in the bypass conduit circulates at least a portion of the heated water from the water exit conduit to the water inlet conduit. A feed-forward sensor positioned in the water inlet conduit between the heat exchanger assembly and the bypass conduit monitors a parameter of the water entering the heat exchanger assembly, and a processor controls the operation of the of the burner assembly in response to the feed-forward sensor.

摘要： A method is provided for reducing degradation in a fuel cell assembly, including at least one fuel cell with a PBI membrane, during standby, operation. The method may include electrochemically consuming an oxidant from a cathode coupled to the PBI membrane in response to a disconnection of an external load and supplying fuel to remove or electrochemically consume any back-diffused oxidant to the associated fuel cell sufficient to replace or consume the back-diffused oxidant while the external load is removed, and/or also may include controlling a standby temperature of the fuel cell. In this way, it may be possible to avoid increased cell voltage decay associated with degradation of the PBI in a simple and cost effective system.
