  • Publication number: 20230207231
    Abstract: A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.

  • Patent number: 11264188
    Abstract: An operator for an electrical switching apparatus includes an actuator configured to be grasped by a user. A linkage is attached to the actuator at a first end of the linkage and configured for extending through an enclosure housing the electrical switching apparatus. An engagement assembly is attached to the linkage at a second end of the linkage such that when the operator is mounted to the enclosure movement of the actuator outside of the enclosure causes movement of the engagement assembly inside the enclosure. The engagement assembly includes an extension arm attached to the linkage and an attachment member attached to the extension arm. The attachment member is configured to engage a toggle of the electrical switching apparatus in the enclosure to move the toggle between at least two positions.

  • Patent number: 8795571
    Abstract: Methods and devices control a de-curling apparatus. A roll of material is fed through a nip formed between a first roller having a concave shape and a second roller contacting the first roller. The second roller has a convex shape mirroring the concave shape. The methods and devices automatically and continually adjust the amount of pressure applied at the nip between the first roller and the second roller as the material is unrolled from the roll into the nip.

  • Patent number: 8668195
    Abstract: A multi-position letterbox media diverter that maximizes productivity includes a gate configured like a tomahawk to allow sufficient space for the diverter to operate immediately after the trail edge of a sheet passes the front edge of the gate and thereby increase gate actuation time. Reversible drives of an inverter are used to direct the sheet to a duplex path while another sheet is simultaneously directed by a lower integrated baffle portion of the gate to an output tray as needed. Thus, reducing the time required for the sheet to be in the inverter path before reversing sheet direction, thereby facilitating a reduction in required transport speed.

  • Publication number: 20140041542
    Abstract: A method and system for controlling a crown height associated with a nip profile includes adjusting pressure of a pressure roll. This may influence the shape of the pressure roll which may influence the nip profile. This may help prevent wrinkling and extend the life of the pressure roll. The pressure roll may be configured to have a varying wall thickness across a width of the pressure roll. The pressure roll may be used for a web application.

  • Patent number: 8583024
    Abstract: A method and apparatus for lifting an elevator plate of a media tray in an image production device is disclosed. The method may include receiving a request to print a print job using stacked media from one of one or more media trays, initiating lifting of the leading edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers, initiating printing of the requested print job from the one of one or more media trays, determining if the amount of stacked media in the one of the one or more media trays is less than a predetermined amount, wherein if it is determined that the amount of stacked media in the one of the one or more media trays is less than the predetermined amount, initiating lifting of both of the leading and trailing edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers.

  • Patent number: 8523174
    Abstract: An improved rotator/translator mechanism includes multiple thin discs that mate with an idler roll to distribute nip pressure and spin at different rotational velocities to produce the same linear velocity at the nip and thereby reduce marking on certain media.

  • Patent number: 8424873
    Abstract: An improved rotator/translator apparatus includes a set of drive rolls driven by a pair of rotator discs. Idler rolls are positioned above each drive roll and spring loaded to provide the required normal force to drive sheets in any direction required. A pair of magnetic couplings couple the drive rolls with the idler rolls. The magnetic couplings are spaced with about a 5 mm gap to allow sheets to pass therethrough. The couplings allow the idlers and the drive rolls to stay aligned. Thus, driving media, registering media and rotating media in a transport is obtained, but with no relative motion or slip between the drive rolls/idler rolls and the media and a larger nip surface area, thereby eliminating marking of certain media.

  • Patent number: 8387972
    Abstract: A media sheet tray includes a first media size sensor, a second media size sensor, a first circuit connected to the first media size sensor, a second circuit connected to the second media size sensor, and a switch within the second circuit. The switch can be in an open position disconnecting a continuity of the second circuit, or in a closed position maintaining the continuity of the second circuit. Media being within the media sheet tray closes the switch. Further, a combination of the first circuit connecting to the first media size sensor and the second circuit being discontinuous indicates that paper is absent from the media sheet tray.

  • Patent number: 8348267
    Abstract: An improved media rotator/translator apparatus includes a cylinder on sphere nip. A series of beveled/spur gears are included, one of which rotates co-axially but independent to the drive roll shafts. This enables the drive rolls to be driven about their own axis while simultaneously allowing for rotation about the roll shaft axis. A ball idler is positioned above each drive roll providing media normal force. Thus, sheet translation, jogging, and rotation is obtained, but with no relative motion, thereby eliminating marking of certain media.
