  • Publication number: 20170115613
    Abstract: A photoconductive drum assembly according to one embodiment includes a photoconductive drum rotatable about a rotational axis in first and second rotational directions. A spring brake has a coiled portion wrapped around a portion of the photoconductive drum at its axial end and around the rotational axis of the photoconductive drum. The spring brake has a first arm and a second arm. The first arm is positioned to flex in an unwinding direction causing the coiled portion to unwind upon the first arm receiving a force in the first rotational direction. The first arm is positioned to flex in a winding direction and to push the second arm in an unwinding direction relieving winding of the coiled portion caused by the flexing of the first arm in the winding direction of the first arm upon the first arm receiving a force in the second rotational direction.

  • Patent number: 8195064
    Abstract: A separator hanger has a body with forward and rearward portions and a central portion interconnecting the forward and rearward portions. The rearward portion has side wing sections extending laterally in opposite directions beyond opposite side edges of the central portion with respective elements thereon adapted to extend through first slots in a packaging insert. The rearward portion also has a tail section between the side wing sections with an element thereon adapted to extend through a second slot in the packaging insert located between and offset from the first slots. Such elements provide the rearward portion in a threaded relationship with the packaging insert so as to detachably attach the rearward portion thereto. The forward portion is adapted to anchor the body to one portion of a device so as to thereby constrain the packaging insert to a position clear of another portion of the device located nearby the packaging insert.
