  • Publication number: 20160355078
    Abstract: A tonneau cover system for a vehicle having a cargo box includes a striker which is adapted to be fixed to the cargo box along with a cover disposed over the cargo box when the cover is in a closed position. Moreover, the cover includes a latch mounted to the frame. The latch engages the striker when the cover is in the closed position. The cover further includes a link which extends from the latch along the frame and a handle coupled to the latch in order to move the latch into a released position which disengages the striker. Finally, the cover includes a coupler which is coupled to the handle. The coupler moves from a first position to a second position and responds to movement of the handle with the link moving relative to the frame in order to facilitate movement of the latch into the released position.

  • Patent number: 9436128
    Abstract: A toner cartridge according to one embodiment includes an outlet port positioned on the front of a housing for exiting toner from the toner cartridge. The toner cartridge includes an engagement member having a first engagement surface and a second engagement surface. The first engagement surface is positioned proximate the rear of the housing to receive an actuation force in a frontward direction of the housing at the rear of the housing. The second engagement surface is positioned proximate the front of the housing below the outlet port. The engagement member is movable from a first position to a second position upon receiving the actuation force. As the engagement member moves from the first position to the second position, the second engagement surface moves in the frontward direction and protrudes from the front of the housing with at least a portion of the front of the second engagement surface unobstructed.

  • Patent number: 9316944
    Abstract: A toner cartridge for use with a developer unit of an image forming device includes a housing having a front, a rear, a top, a bottom, a first side and a second side. The housing has a reservoir for holding toner. An outlet port is positioned on the housing for transferring toner from the reservoir to the developer unit. An alignment slot on the front of the housing is open at a bottom end of the alignment slot to receive an alignment pin of the developer unit. The alignment slot has a width that narrows from the bottom end of the alignment slot to a middle section of the slot and that widens from the middle section of the alignment slot to a top end of the alignment slot.

  • Publication number: 20160075220
    Abstract: A tonneau cover system for covering a space. The system includes a frame having rails. A cover is disposed over the frame for covering the space. A block, a receiver, an anchor and a latch are all coupled to the frame.

  • Patent number: 9279307
    Abstract: A bridge plug can be deployed downhole and retrieved using a retrieval tool disposed on jointed or coiled tubing or on another bridge plug. Internally, the bridge plug has a sleeve that is movable on a stem of the plug's tailpiece. When in a first position, the sleeve prevents fluid communication through ports in the stem so that circulated fluid from the retrieval tool can be used to clear debris from the plug during retrieval. When the retrieval tool engages the sleeve in the plug, pulling up on the tool moves the sleeve to an intermediate position in which fluid pressure is equalized across the plug. Further pulling up on the tool locks the sleeve in a further position on the stem so that circulated fluid from the retrieval tool will pass directly to the stem's ports. Movement of the sleeve by the retrieval tool also releases the engaged slips and packing element on the bridge plug's mandrel.

  • Patent number: 9229367
    Abstract: A carriage assembly according to one example embodiment includes a cradle pivotably mounted on a base. The cradle has a cartridge storage area sized to receive and hold a toner cartridge. The cradle is pivotable between a loading position for loading and unloading the toner cartridge and an operating position for operating the toner cartridge. A hold-down feature is mounted on the base adjacent to the cradle in a substantially stationary position relative to the cradle movement. When the cradle is in the loading position, the hold-down feature is positioned clear of an insertion and removal path of the toner cartridge into and out of the cradle and, as the cradle moves toward the operating position and when the cradle is in the operating position, the hold-down feature is positioned to engage a stop on the toner cartridge to prevent the toner cartridge from separating from the cradle.

  • Patent number: 9164425
    Abstract: A toner cartridge according to one example embodiment includes a housing having a front, rear, first side, second side, top and bottom forming a toner reservoir. An outlet port is positioned on the front of the housing proximate the first side for transferring toner out of the reservoir. A drive gear is positioned on the front of the housing and has a center proximate the second side for receiving rotational power. A cavity is formed in the bottom of the housing. A latch catch is positioned in the cavity on an inner side of the front of the housing for receiving a latch for securing the toner cartridge in an image forming device. The latch catch is positioned closer to the bottom of the housing than the outlet port and the drive gear and between the center of the drive gear and the outlet port in the side-to-side direction.

  • Patent number: 9152083
    Abstract: A carriage assembly for an image forming device according to one example embodiment includes a plurality of cradles mounted on a base. Each cradle has a cartridge storage area sized to receive and hold a corresponding toner cartridge. Each of the cradles is independently pivotable between a loading position for loading and unloading the toner cartridge into and out of the cradle and an operating position for operating the toner cartridge in the image forming device. Each of the cradles is biased toward the loading position. A latch assembly is configured to retain the cradles holding the corresponding toner cartridges in the operating position. The latch assembly has user-actuated engagement features for individually releasing the cradles from the operating position to the loading position for unloading the corresponding toner cartridge.

  • Publication number: 20150114639
    Abstract: Re-treatment of a formation having a wellbore, which can be an open hole or a cased hole lined with casing, involves deploying a tubing string in the casing having tools disposed at intervals thereon. The tools position on the tubing string, and the tubing string with the tools thereon is inserted into the casing. Biasing rings of the tools passively engage with the casing. The annulus is accessed between the tubing string and the casing at the intervals between the tools. For example, sliding sleeves on the tubing string can be opened (selectively), or new plug and perforation operations can be used to create perforations in the tubing string at desired intervals between the tools. With access achieved, retreatment is pumped down the tubing string, out the access to the annulus, and at least partially sealed by the engaged rings in the intervals between the tools.
