  • Patent number: 5193750
    Abstract: A peristaltic voltage block (34) couples a dispenser (10) to a source (20) of coating material. The peristaltic voltage block (34) has a length (220) of resilient conduit, a wall against which the resilient conduit lies in generally planar loops (222), and a rotor (246) including rollers (250, 350) for movably contacting the length (220) of resilient conduit at multiple contact points for substantially dividing the coating material in the peristaltic voltage block (34) into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material source (20). Either the wall or the rollers (250, 350) includes first regions where the loops (222) of resilient conduit lie, and second, raised regions. The second, raised regions adjacent the first regions retain the loops (222) of resilient conduit (220) in position.

  • Patent number: 5009573
    Abstract: A variable occlusion device includes a device housing having an occlusion track adapted to receive one or more loops of flexible tubing and having an arcuate reactive surface. The device also includes a rotor member mounted for rotation within the housing about a device axis. The rotor includes a number of carriage passageways or tracks, each passageway or track with an occluding member carriage and occluding member assembly movably mounted therein. The carriage and occluding member assemblies are each adapted to move between an extended position in which the occluding member bears against and collapses the tubing received in the occlusion track, and a retracted position in which the occlusion member is drawn away from and out of contact with the tubing in the occlusion track. The peristaltic device also includes a fluid distribution system for providing an operating fluid from a remote fluid supply under a desired pressure to the carriage passageways of the rotor.
