Inventor: DOPF ANTHONY R
IPC: E21B47/12
Filed: 2007-02-09
Abstract: A gap sub assembly can be used to form an electrical isolation in a drill string, across which a voltage is applied to generate a carrier signal for an electromagnetic (EM) telemetry system. The assembly comprises two conductive generally cylindrical components fashioned with a matching set of male and female rounded coarse threads, held such that a relatively uniform interstitial space is formed in the overlap space between them. The third component is a substantially dielectric electrical isolator component placed into the gap between the threads that effectively electrically isolates the two conductive components. Injecting the dielectric material under high pressure forms a tight bond resistant to the ingress of conductive drilling fluids (liquids, gases or foam), thus forming a high pressure insulating seal.

Title: Pivotal base for enclosed hose reel
Inventor: ROSINE LYLE A
IPC: B65H75/38
Filed: 2008-01-22
Abstract: A base assembly, including wheels, is attachable to the bottom of a hose reel enclosure. This assembly enables the hose reel enclosure to pivot about a vertical axis.  This pivotal movement of the hose reel enclosure permits a hose to be withdrawn from and wound back onto the hose reel in the enclosure while remaining substantially perpendicular to the longitudinal axis of the hose reel. This also enables a hose to be taken up evenly onto the hose reel and played out from the hose reel without tipping over the hose reel enclosure. In one embodiment, the base assembly is attached to the bottom of a hose reel enclosure. Two wheels are mounted at one end portion of the assembly and a stake is positioned in a member mounted between the end portions of the base assembly. The stake is driven into the ground below the hose reel enclosure.  The wheels enable the hose reel enclosure to be pivoted along the ground about the stake to enable a hose to be evenly taken up onto the hose reel and played out from the hose reel without tipping the hose reel enclosure over. In another embodiment, the wheels and stake are mounted directly onto the hose reel enclosure.
