  • Publication number: 20140152744
    Abstract: A septum device usable with a fluid interconnect unit of a fluid supply device is disclosed. The septum device includes a resilient main body to be inserted into the fluid interconnect unit of the fluid supply device. The resilient main body includes an interior septum surface forming a longitudinal opening to removably receive a fluid extraction member and an exterior septum surface. The interior septum surface includes interior engagement members extending toward the opening and spaced apart from each other in a longitudinal direction. The exterior septum surface includes exterior engagement members extending away from the opening and spaced apart from each other in the longitudinal direction to engage an interior interconnect surface of the fluid interconnect unit.

  • Patent number: 8727516
    Abstract: In one example, a fluid cartridge includes a reservoir for holding a fluid, an electrical interface, an alignment feature, and a keying feature. The alignment feature is configured to, as the cartridge is inserted into a receiver, bias the electrical interface against a corresponding electrical interface on the receiver. The keying feature discriminates the cartridge from other fluid cartridges to prevent the cartridge from being inserted incorrectly into the receiver.

  • Publication number: 20140055537
    Abstract: An ink cartridge for an inkjet printer includes a bottom face and a front face; an ink interface on the front face of the ink cartridge for connection to a cartridge receiving structure; a guide interface in the bottom face for guiding the cartridge along a straight line during insertion into the cartridge receiving structure for connecting the ink interface; a latch track disposed in the bottom face of the ink cartridge to guide a latch of the cartridge receiving structure; a latch stop disposed in the latch track for engaging the latch, where the latch track comprises a locking track and an unlocking track to accommodate movement of the latch with respect to the latch stop, the locking track being at least partly separate from the unlocking track; and a latch guide for redirecting the latch towards the locking track, rather than the unlocking track.

  • Publication number: 20140049583
    Abstract: An ink cartridge for an inkjet printer includes a bottom face and a front face; interfaces on the front face of the ink cartridge for connection to a cartridge receiving structure, the interfaces including an ink interface; a guide interface in the bottom face for guiding the cartridge along a straight line for connecting the interfaces; and a latch stop and a latch track disposed in the bottom face of the ink cartridge to guide and retain, respectively, a latch of the cartridge receiving structure. The latch track includes a locking track and an unlocking track to accommodate movement of the latch with respect to the latch stop, the locking track being at least partly separate from the unlocking track, the movement of the latch being along the locking track into a locked engagement position at insertion, and along the unlocking track into an unlocked position at ejection.

  • Patent number: 8474960
    Abstract: An ink cartridge for an inkjet printer includes a bottom face and a front face; interfaces on the front face for connection to a cartridge receiving structure, the interfaces including an ink interface; a guide interface in the bottom face for guiding the cartridge along a straight line during insertion in the cartridge receiving structure for connecting the interfaces, where the guide interface comprises a guide track for guiding a T-rail guide of the cartridge receiving structure, said guide track extending parallel to said straight line; and a latch track and a latch strop disposed in the bottom face of the ink cartridge to guide and retain, respectively, a latch of the cartridge receiving structure. The guide track and the latch track are formed by one integral cut out in the bottom face of the cartridge.

  • Patent number: 3964748
    Abstract: A mechanical apparatus for playing a game of chance for entertainment. By manipulation of a mallet-like device a resilient ball is caused to bounce about within a hollow open-space, then settle into any one of nine indentures in a scoring face which is marked to represent a tic-tac-toe board. A matching tic-tac-toe score card for marking results and determining the winner of the game may be included. Although designed primarily as a toy for children, it has appeal to those of all ages.
