  • Patent number: 7581734
    Abstract: A sealing apparatus is combined in a housing, such as a motor protector housing, having a hole extending therethrough. A shaft is movably disposed through the hole. A lip is disposed about the shaft and a ring is movably disposed about the shaft between the section and the lip. Sealing surfaces exist on opposite sides of the ring and on corresponding portions of the lip and the section. A polymeric coating is applied to at least one of the sealing surfaces. The polymeric coating may include a PEEK composite applied by an HVOF thermal spray process. A compressed spring assembly may be utilized to ensure a continuous seal.

  • Patent number: 6541706
    Abstract: A system of resheathing armored power cables that provides multiple uses in harsh environments, such as those found in wellbore applications, before the integrity of the inner core of the cable is degraded. The resheathing system utilizes a sacrificial insulated jacket providing additional protection to the cable's inner core. The sacrificial jacket and the outer armor layer may be easily removed by the use off a rip cord or multiple rip cords. Removal of the sacrificial jacket and armor layer allow the inner core of the cable to be resheathed in the field for reuse.
