Abstract: A heated fluid conduit has a body with a semi-conductive material disposed therein with an electrical power supply coupled to the conduit to provide a voltage across the conduit and a current therethrough, heating the fluid conduit. A fluid conduit heating system comprises a semiconductive sleeve disposed over a fluid conduit and an electrical power supply coupled to the ends of the sleeve to provide a voltage across the sleeve and a resulting current through the semiconductive sleeve, heating the sleeve and conduit Alternatively, one terminal of the electrical power supply is coupled to each end of the sleeve or conduit, and another terminal of the electrical power supply is coupled to the sleeve or conduit therebetween, to provide parallel heating circuits.

Abstract: A crimper system having a slide frame with a base and a movable head slidably mounted on the slide frame, with a crimp zone opening defined between the base and head, including a dual compound leverage mechanism having two tension arms with lower ends pivotably attached to the base; two compression arms with lower ends pivotably attached to the movable head; and the upper end of each tension arm pivotably attached to the upper end of a corresponding one of the compression arms forming two elbow joints defining acute angles between each tension arm and its corresponding compression arm; a screw drive mechanism; and a stepped crimp-setting mechanism. Also provided is a tool, system and method for quick, easy removal, installation and storage of multiple-die, crimper die sets. The system includes a set of interconnected dies. The tool engages the connectors for pulling the die set out of a crimper.
