  • Patent number: 8465136
    Abstract: An ink cartridge refill apparatus includes an ink cartridge holder and an ink refill unit which are matched with each other. The ink cartridge holder has an accommodation chamber therein to accommodate an ink cartridge. The ink refill unit includes an ink tank and an ink delivery unit. An air extraction mechanism is provided on the ink cartridge holder to extract air from the ink cartridge. The ink cartridge holder has a passage for the air extraction mechanism to extract air relative to a nozzle of the ink cartridge. Through the air extraction mechanism, the ink cartridge is primed after being filled with ink, so that ink can freely flow to the nozzle of the ink cartridge from the ink tank of the ink cartridge. Compared to the prior art ink cartridge refill apparatus which needs an auxiliary tool to extract air after being refilled, the present invention is convenient for operation and can prevent the ink cartridge from leaking.

  • Publication number: 20130031756
    Abstract: A self-locking fastener includes a base member and a clip member. The base member includes a buckle base, a buckle point and a buckle pin. The clip member includes a plurality of resilient locking arms disposed toward one side thereof. When the clip member is coupled to the base member, the buckle point of the base member extends out along the resilient locking arms. The resilient locking arms are fitted on the buckle pin. Free ends of the resilient locking arms lean against the inner end of the buckle point to stop the buckle point from sliding out along the resilient locking arms. Through the resilient locking arms and the buckle point, the free ends of the resilient locking arms are to lean against the inner end of the buckle point to achieve a self-locking connection of the base member and the clip member. The structure of present invention is simple. When packing a product, the two sheets of material are only required to have holes.

  • Patent number: 7631869
    Abstract: The present subject matter relates generally to a system and method for controlling functions in a mail sorting system based on gap length measurement and tracking. The system and method includes a plurality of sensors located along one or more mail piece transport paths. The sensors are used to collect data regarding the gap length between each mail piece transported through the system. The gap length data is processed and stored within a controller/processor that uses the gap lengths to control the operation of one or more devices within the mail sorting system. For example, the gap lengths may be used to control the operation of a diverter, a printer or any other electromechanical, hardware or software device. The gap lengths can be used to trigger and/or inhibit the operation of the one or more devices.

  • Publication number: 20080204528
    Abstract: An ink cartridge including a housing, an ink outlet arrangement, an air vent arrangement, and at least one handle. The housing includes at least a top wall, a bottom wall, and a plurality of side walls that define an ink reservoir. The ink outlet is positioned at the bottom wall. The air vent arrangement includes an air inlet to the ink reservoir that is positioned adjacent to the bottom wall. The handles extend from opposing sides of the housing. The handles each include a pliable portion. The pliable portion is arranged spaced apart from the side wall of the housing from which the handles extend. The ink cartridge can further include an extension member that extends from the bottom housing at the bottom wall. An extension member is configured to mount an electronic chip.

  • Publication number: 20080165232
    Abstract: An ink container includes a housing that defines an ink reservoir, an air vent in air flow communication with the ink reservoir, and an ink outlet in ink flow communication with the ink reservoir. The air vent provides air flow communication between atmosphere and the ink reservoir. The ink outlet provides an ink flow path out of the ink reservoir through a leading surface of the housing. The ink outlet and air vent can be positioned on different sides of the cartridge or on the same side of the housing. The leading surface faces in a generally horizontal direction. The leading surface can include a contoured shape such as a convex shape.

  • Publication number: 20080165214
    Abstract: An ink cartridge including a housing, an ink outlet, and an air vent arrangement. Some examples further include a reflector positioned within the housing. Decreasing an ink volume in the housing below a predetermined level permits a light beam directed into the housing to be reflected off from the reflector thereby indicating a low ink level. The air vent arrangement can provide a source of air into the ink reservoir at a location adjacent a bottom internal surface of the housing. Providing air to the ink reservoir at this location helps maintain a negative pressure condition in the ink reservoir that prevents ink from unintentionally dripping out of the ink cartridge prior to mounting the cartridge to a printer. The air vent arrangement includes a one-way valve and an air channel that provides air to the one-way valve from an inlet that is positioned on the housing vertically above the one-way valve.
