  • Patent number: 6143985
    Abstract: In a reproduction machine with modular components movable relative to the mainframe of the machine, a cable controlling system for maintaining a protected electrical cable interconnection when the modular component is moved relative to the mainframe, with a constant force spring system connecting a pulley cable guide to the mainframe to retract the pulley cable guide towards the mainframe when the modular component is moved towards the mainframe, and to allow the pulley cable guide to move away from the mainframe with the substantially constant force when the modular component is moved away from the mainframe, a single bight in the cable of a defined minimum relatively large wrap angle, and a linear cable guide channel member internally confining a substantial portion of the extendable and retractable single bight portion of the cable.

  • Patent number: 5742872
    Abstract: A commutating connector which electrically connects conductive paths of a rotating electroded donor roll to a voltage source. The connector includes a housing made of an electrically insulating material. The housing defines a chamber to receive the donor roll. An electrically conductive brush is disposed in the chamber. The brush is mounted in pressing engagement against the conductive paths on the electroded donor roll to electrically connect the voltage source to the conductive paths on the electroded donor roll. The chamber is divided by a partition into a commutating and a non-commutating area. The housing has ports for receiving air to prevent particulate matter from accumulating between the brush and donor roll.

  • Patent number: 4544225
    Abstract: The present invention is concerned with a pivotable connector latch for securing together a pair of mating electrical connector members. The latch includes a pivot end secured to one end of one of the electrical connector members and a clamp end having a U-shaped member including one leg with a resilient spring for snapping the latch onto another end of the connector member. An elongated locking section of the latch, with an elongated lip between the pivot end and the clamp end fixedly secures the connector members together. The other leg of the U-shaped member is a straight clip section with a beveled edge for engaging one of the connector members.
