Patent CA-2152560-C (CA)
Inventor: ELLISTON TOM
IPC: E21B19/22
Filed: 1995-06-23
Granted: 2005-11-15
Abstract: A coil tubing injector unit is shown for injecting tubing into a well bore. A main injector frame is positioned adjacent the well bore and includes a longitudinal opening which defines a vertical run for the injector unit which is alignable with the well bore vertical axis. Gripper block assemblies are carried on the main injector frame and include plier-like halves which are pivotable between an open position and a closed, gripping position as the assemblies enter the vertical run so that the plier halves grip a selected length of tubing fed into the main injector frame along the central vertical axis of the injector unit to inject the tubing into the well bore. The profile of the vertical run is designed to minimize loading on the gripper block assemblies. The section modulus of the material used to manufacture the vertical run is also designed to allow a controlled flex of the run in order to soften the gripper loading as the gripper block assemblies enter the vertical run.

Patent CA-2190824-C (CA)
Inventor: REED STUART EUGENE
IPC: F28D15/02
Filed: 1996-11-20
Granted: 1999-08-24
Abstract: A flexible, pressurized insert for insertion within the hot (evaporator) side of an inclined heat pipe that forms a part of a heat pipe heat exchanger.  This insert is employed in order to prevent such heat pipe from rupturing in the event the working fluid contained therein freezes.  This insert is constructed of a thin-walled flexible material that is capable of being deformed (i.e.  compressed)  thereby absorbing the expansion pressures exerted by the working fluid should the working fluid freeze or be exposed to freezing temperatures.  By such absorption, the outer heat pipe itself will not be over-pressurized which might otherwise lead to its rupture.  Upon the thawing of the working fluid, the pressurized insert (which is at a pressure greater than that of the working fluid in its non-frozen state) will once again regain its shape.
