Abstract: An ink cartridge has a first wall and a plurality of side walls extending from the first wall to form an internal cavity between the side walls and the first wall. The internal cavity is substantially filled with ink. A cover is attached to the plurality of the walls. An ink supply port is formed in one of the plurality of side walls. An ink supply flow path is formed in the first wall and extends to the ink supply port. A porous member is interposed between the ink supply flow path and the ink supply port or a wall of the cartridge for minimizing formation of bubbles in ink in the ink supply flow path and the ink supply port. Grooves are also provided in the ink supply flow path to further reduce formation of bubbles.

Abstract: An ink cartridge has a body having a plurality of side walls forming an internal cavity therein. An ink supply flow path is formed in one of the side walls. An ink supply port is formed in another of the side walls. The port is fluidically connected to the ink supply flow path. A memory device for storing information for the ink. A housing is provided for the memory device. The housing has first and second walls extending from a surface into which said memory device is installed for aligning the memory device and maintaining electrical contact between the memory device and an electrical contact assembly of a printer.

Abstract: An ink cartridge has a plurality of walls forming an internal cavity which is substantially filled with ink, and an ink supply flow path provided in one of the walls of the ink cartridge. An ink supply port is provided in another of the walls of the cartridge, wherein the ink supply flow path connects to the ink supply port. The ink supply flow path includes a first compartment and a second compartment. The first compartment houses a wicking member, and the second compartment is configured to trap air bubbles formed in ink as it travels through the ink supply flow path.

An ink supply flow path formed in one of the side walls. An ink supply port is formed in another of the side walls, wherein the ink supply flow path extends to the ink supply port. The side wall having the ink supply port further has one or more angled surfaces for guiding the ink cartridge into a printer. A tab is provided for aligning the cartridge during installation into the printer. A pad is provided to overcome the friction force of installing the cartridge into the printer.

Abstract: A variable torque device for maintaining constant tension in a web of material as the web is unwound from a supply roll. The variable torque device includes a lead screw attached to the shaft of the supply roll via an appropriate gear ratio. A coil spring is located between a hub on the lead screw and a set of rings and friction pads. As the lead screw rotates, the hub translates, thus changing the displacement of the coil spring, which in turn changes the loading of the rings and friction pads. With a full supply roll the coil spring is compressed so as to create an amount of torque to create the desired web tension. As the supply roll unwinds, the rotation of the lead screw translates the hub to expand the coil spring, reducing the torque and maintaining the web tension constant.
