Abstract: Systems and methods for continuous injection of fluid, in some examples these apparatuses may include a manifold, a pair of reciprocating pistons, and an actuation control that may apply both suction (aspiration) and injection of fluid as part of the same actuation. The systems and methods may be configured to simplify the operation of a continuous fluid injection system, including one that aspirated prior, to injection to confirm the absence/presence of blood.

Abstract: Copy sheets having a re-fusable xerographic toner along an edge thereof are bound into booklets by arranging the sheets in a stack and re-fusing the toner so that the re-fused toner adheres adjacent sheets together. The re-fusing operation can be accomplished after each group of a few sheets is received from a copier so that the finisher operation can be carried on at the same rate copies are produced by the copier. Alternately, a larger stack of sheets can be bound together in an off-line basis by a simple heating step.

Abstract: Copy sheets having a re-fusable xerographic toner along an edge thereof are bound into booklets by arranging the sheets in a stack and re-fusing the toner so that the re-fused toner adheres adjacent sheets together. The re-fusing operation can be accomplished by a heating shoe and a patterned heating bar after each group of a few sheets is received from a copier so that the finisher operation can be carried on at the same rate copies are produced by the copier. Alternately, a larger stack of sheets can be bound together in an off-line basis by a simple heating step.

Abstract: A recirculating feeder for a copier employs a separator member that initially engages the top sheet of a multisheet document in a tray and incrementally moves downwardly under the influence of gravity as individual sheets are fed from the bottom of the document to the copier exposure platen and returned to the top of the document in the tray. The separator member is mounted on a shaft that carries a cam which is adapted to open and close a switch. When the sheet initially engaged by the separator member is fed, the separator member falls below the tray. At this position, the cam closes the switch which energizes a motor. The energized motor drives a roller which engages the surface of a contoured roller connected to the shaft. The separator member is thereby driven towards return engagement with the top document sheet. Prior to the separator member returning to such engagement, the surface of the contoured roller disengages from the drive roller.
