Abstract: A multiple valve compressor head having a casing defining an intake chamber in selective communication with a cavity through a plurality of one-way intake valves and an exhaust chamber in selective communication with the cavity through a plurality of one-way exhaust valves is disclosed. The casing further defines an inlet port for the entry of gas into the intake chamber and an outlet port for forcing out compressed gas from the exhaust chamber. In operation, the multiple valve compressor head is in operative engagement with a reciprocating diaphragm that draws the gas into the intake chamber and then the cavity during the intake stroke of the diaphragm, while expelling compressed gas from the cavity and through the outlet port during the exhaust stroke of the diaphragm.

Abstract: Improved methods and apparatuses are provided for determining when and how to display non-modal messages relating to user input portions of a graphical user interface (GUI). One method includes displaying at least one user input portion within a GUI and determining if the user input portion is in an invalid state by determining that valid user input associated with the user input portion has not been received. The method further includes displaying a non-modal message within the GUI. The non-modal message is visibly graphically associated with the user input portion. The method also includes automatically applying a focus of the GUI on the user input portion. As long as the focus of the GUI remains on the user input portion, the method includes displaying the non-modal message until the user input portion is determined to be in a valid state.

Abstract: A turbine engine component, such as a turbine blade, has an airfoil portion, a plurality of cooling passages within the airfoil portion with each of the cooling passages having an inlet for a cooling fluid. Each inlet has a flared bellmouth inlet portion. The turbine engine component may further have a dirt funnel at the tip of the airfoil portion, a platform with at least one beveled edge, and an undercut trailing edge slot.

Abstract: A bag mask resuscitator including flexible tubing having a proximal end and a distal end with the proximal end engaged to a resuscitation bag and the distal end adapted for engagement with a valve assembly is disclosed. The valve assembly includes a coupling member adapted for quick engagement and disengagement of the flexible tubing from the valve assembly using a simple action.
