| 20090189942 | HUMIDITY CONTROLLED CONTAINER FOR DEVICE INCLUDING A LIQUID - A container assembly includes a container including an inside and an outside, the container being sealed to isolate an environment inside the container from an environment outside the container. An electronic device is disposed inside the container. The electronic device includes an internal cavity, the internal cavity including a liquid. A predetermined mass of desiccant material is disposed inside the container. An air path exists between the desiccant material and the liquid in the internal cavity of the electronic device. The predetermined mass of desiccant material and the liquid maintain a humidity level of the environment inside the container within a desired range. | 07-30-2009 |
| 20090219353 | DUAL SEATING QUICK CONNECT VALVE - A valve includes a stem, a cap, and a deformable lip. The stem includes a first sealing portion and has a longitudinal axis. The cap is connected to the stem and includes a passageway. The deformable lip extends from a periphery of the cap and includes a second sealing portion. The stem is displaceable relative to the deformable lip along the longitudinal axis of the stem to open the first sealing portion and close the second sealing portion to allow fluid to move through the passageway in the cap. | 09-03-2009 |
| 20090309940 | LIQUID STORAGE TANK INCLUDING A PRESSURE REGULATOR - A liquid tank for storing liquid includes a liquid chamber, a vent, and a pressure regulator. The liquid chamber includes a wall and the vent leads to atmosphere. The pressure regulator includes an enclosure, a first capillary media member, and a second capillary media member. The enclosure extends into the liquid chamber from the wall of the liquid chamber and includes a hole opening into the liquid chamber. The first capillary media member has a first pore size and is located in the enclosure proximate to the vent. The second capillary media member has a second pore size and is located in the enclosure adjacent to the hole. The second pore size is less than the first pore size. | 12-17-2009 |
| 20090309941 | INK TANK FOR INKJET PRINTERS - The present invention relates to an ink tank for an ink jet printer. The invention further relates to a method of manufacturing the ink tank, as well as well as a method of refilling the ink tank. The ink tank includes an ink tank body and an ink tank lid bonded to the ink tank body at a bond joint. The ink tank lid comprises an opening that leads to a holding area that is adapted to contain a capillary media therein. The holding area comprises a wall that forms a boundary between the capillary media and an enclosure defined by the ink tank body and the ink tank lid. The opening is sized to permit an insertion and removal of the capillary media to and from the holding area when the ink tank lid is bonded to the ink tank body at the bond joint. | 12-17-2009 |
| 20100149287 | SELECTABLE FILL VOLUME FOR INK RESERVOIR - A method for filling an ink tank to one of several selectable ink fill volumes, by providing an ink tank including an ink reservoir having a maximum fill volume V and selecting an ink fill volume V | 06-17-2010 |
| 20110025786 | INK RESERVOIR WITH A BIASING VALVE - An ink reservoir that contains ink and is detachably mountable to a printhead, the ink reservoir includes a free ink chamber for containing the ink; a valve assembly extending into the free ink chamber and including a first position for permitting ink to flow from the ink reservoir and a second position for stopping the flow of ink from the ink reservoir; and a wick that receives ink from the ink reservoir for transfer to the printhead. | 02-03-2011 |
| 20110205268 | METHOD FOR INK TANK PRESSURE REGULATION - A method of regulating pressure in an ink tank including biasing an aperture of the ink tank to a closed position, withdrawing ink from an outlet port of the ink tank to provide a reduced internal pressure in the ink tank. The aperture is opened in response to the reduced internal pressure in the ink tank. The aperture leads to ambient atmospheric pressure outside the ink tank. The biasing step can include using biasing a valve member with a predetermined force against a valve seat at a contact region between the valve member and the valve seat. Opening of the aperture can include moving the member away from the valve seat in response to a difference in pressure between ambient atmospheric pressure and the reduced internal pressure in the tank. | 08-25-2011 |
| 20110205318 | INK TANK CHECK VALVE FOR PRESSURE REGULATION - An ink tank having a tank body and an aperture leading to an outside of the tank body. A valve is biased to close the aperture but is movable to open the aperture by a reduced pressure within the tank body relative to an external pressure outside the tank body. The valve contacts a valve seat and is biased with a predetermined force against the valve seat by a spring. The predetermined force and the area of a contact region between the closing member and the valve seat determine how much pressure difference is needed to open the aperture. | 08-25-2011 |
