The valve actuator opens the air inlet valve in response to the ink outlet valve opening to establish fluid communication with the inkjet printhead. The ball in the ink outlet valve is adapted to engage one end of the sliding shaft to slide the shaft towards the air inlet valve, whereat the other end of the shaft engages the ball of the air inlet valve against the bias applied thereon. | 04-22-2010 |
20100141706 | NON-CONTACT METHOD OF MAINTAINING INKJET PRINTHEAD - A method of maintaining an ink ejection face of a pagewidth printhead. The method includes the steps of: flooding the face with ink; positioning a transfer roller adjacent the face and without contacting the face; rotating the transfer roller and simultaneously transferring flooded ink from the ink ejection face onto the transfer roller; and removing ink from the transfer roller. | 06-10-2010 |
20100225702 | Printhead Assembly Incorporating Plural Printhead Integrated Circuits Sealed To Support Member With Polymer Sealing Film - A pagewidth printhead assembly includes a plurality of printhead integrated circuits linked end to end across a width of the pagewidth printhead assembly; a support molding to which the plurality of printhead integrated circuits are sealed, the support molding defining a plurality of ink channels; a plurality of etched channels provided on an underside of each printhead integrated circuit, each etched channel defining along a length thereof a plurality of ink inlets for receiving ink from one of the plurality of ink channels; and a polymer sealing film for sealing the printhead integrated circuits to the support molding, the polymer sealing film defining therethrough a plurality of openings. Each of the plurality of etched channels is divided into two or more separate channel sections separated by respective channel wall structures. Each opening of the polymer film is in fluid communication with ink inlets of two separate channel sections. | 09-09-2010 |

20090071120 | Combined cycle integrated combustor and nozzle system - An engine that operates and produces the entire required vehicle thrust below Mach 4 is useful for a Hypersonic combined cycle vehicle by saving vehicle and engine development costs. One such engine is a combined cycle engine having both a booster and a dual mode ramjet (DMRJ). The booster and the DMRJ are integrated to provide effective thrust from Mach 0 to in excess of Mach 4. As the booster accelerates the vehicle from Mach 0 to in excess of Mach 4, from Mach 0 to about Mach 2 incoming air delivered to the DMRJ is accelerated by primary ejector thrusters that may receive oxidizer from either on-board oxidizer tanks or from turbine compressor discharge air. As the TBCC further accelerates the vehicle from about Mach 0 to in excess of Mach 4 exhaust from the turbine and exhaust from the DMRJ are combined in a common nozzle disposed downstream of a combustor portion of said DMRJ functioning as an aerodynamic choke. | 03-19-2009 |
20090205311 | Combined cycle missile engine system - An insensitive combined cycle missile propulsion system includes a solid fuel contained within a first section of the missile, a liquid oxidizer contained within a second section of the missile and a solid oxidizer contained within a third section of said missile. A first conduit has a first valve communicating the fuel and the oxidizer and a second conduit, spatially removed from the first conduit, has a second valve communicating the fuel and the oxidizer. An inlet system for delivering atmospheric oxygen for combustion with the fuel rich gases generated within the missile and a nozzle exhausts combustion products that result from combustion of the fuel, the liquid and solid oxidizers, and air. | 08-20-2009 |
20090211258 | Rocket nozzles for unconventional vehicles - Improved rocket nozzle designs for vehicles with nozzles embedded in or protruding from surfaces remote from the desired thrust axis. The nozzle configurations are for rocket vehicles where the nozzles are not located at the optimal thrust axis of the vehicle. Two examples include nozzles located on the forward end of the vehicle (also called tractor nozzles) and attitude control nozzles located on the periphery of the vehicle. More particularly, the disclosed nozzle shapes enhance the axial thrusts and/or maneuver torques on the vehicle. These unconventional nozzle shapes improve vehicle performance. | 08-27-2009 |
