Patent number: 6425441Abstract: A gripper block for use in an endless chain in a device for moving a generally cylindrical object longitudinally, as into or out of a well. The block has a first portion adapted to engage the endless chain and a second portion adapted to frictionally engage the object. At least a portion of the block is made from a resilient material that engages the tubing.Type: GrantFiled: February 16, 2001Date of Patent: July 30, 2002Assignee: Vita International, Inc.Inventors: Khaled M. Shaaban, James A. Bodhaine, Alexander Sas-Jaworsky, II

Patent number: 6345508Abstract: A heat exchanger is disclosed having a first chamber, a second chamber positioned inside the first chamber, and a third chamber positioned inside the second chamber. The first, second, and third chambers are in coaxial alignment. A first portion of a first helical tube is positioned inside the second chamber and a second portion of the first helical tube is positioned inside the third chamber and a second helical tube is positioned inside the first chamber. The heat exchanger heats a cryogenic liquid to a gas phase using at least three different heat transfer fluids in one contained unit without mixing any of the fluids in the exchanger.Type: GrantFiled: April 10, 2000Date of Patent: February 12, 2002Assignee: Vita International, Inc.Inventors: Jim Bodhaine, Hany E. Hassanein

Patent number: 6095240Abstract: A heat exchanger having a plurality of coaxially aligned chambers for providing radiant, thermal heat transfer between a plurality of separately contained fluids within a single unit and a helical tube having at least one portion positioned within at least one of the chambers. A first, second, third, and fourth chambers are in coaxial alignment. The heat exchanger heats a cryogenic liquid to a gas phase using four different heat transfer fluids in one contained unit without mixing any of the fluids in the exchanger, thus reducing the size and cost, while increasing the efficiency of the heat exchanger.Type: GrantFiled: July 1, 1998Date of Patent: August 1, 2000Assignee: Vita International, Inc.Inventors: Hany E. Hassanein, James A. Bodhaine

Patent number: 5826610Abstract: A breakaway coupling device is provided having a male and female valve body. The female valve body, a plurality of boltholes extending therethrough, and a plurality of boreholes extending therethrough. The female valve body further defines a first cavity traversing the female valve body. The male valve body has a plurality of flange pairs and a plurality of boreholes aligned with the boreholes in the female valve body. There are a plurality of tie bolts attached to the female valve body through the plurality of boltholes. The tie bolts are received by the plurality of flange pairs on the male valve body. There are a plurality of shear pins. Each one of the plurality of shear pins intersects each flange pair and each one of the plurality of tie bolts at an angle perpendicular to the tie bolts thereby connecting the male valve body to the female valve body. There are plurality of guide pins closely received by the boreholes in the male valve body and the female valve body.Type: GrantFiled: May 5, 1997Date of Patent: October 27, 1998Assignee: Vita International, Inc.Inventor: James Bodhaine
