Abstract: A faucet assembly has a faucet housing having an outlet, a conduit defining a flow path from a supply of water through the housing to the outlet, an openable and closable servovalve in the conduit, and an openable and closable manual valve in the conduit and having a control element movable between a full-flow open position, an intermediate-flow middle position, and a no-flow closed position. A position-detecting switch subassembly mounted on the housing engages the control element and a proximity detector has a detection field adjacent the outlet. A controller connected to the proximity detector, to the switch subassembly, and to the servovalve serves in the closed position of the element for deactivating the detector and closing the servovalve. In the middle position of the element the controller opens the servovalve on detection of an object in the field of the proximity detector. In the open position of the element the controller disables the detector and opens the servovalve.

Abstract: An arrangement for reducing the gap formed by the adjustable axial-flow guide vanes of fluid flow engines, such as gas turbine engines, between the root-sided lower edges of the vane airfoil and the thereto contiguous outer wall of an annular flow passageway. Grooves are formed in the outer wall of the flow passageway above a leading and/or trailing lower edge of the vane airfoil; a soft vane base-covering coating filling said grooves; and recesses formed in the coating-filled grooves slightly above the pivot plane of the respective lower vane edges.
