Patent CA-2003475-A1 (CA)
Inventor: COTHERMAN ROBERT D
IPC: E21B43/12
Filed: 1989-11-21
Abstract: A submersible pump system and method for producing oil from gassy wells is disclosed in which at least first- and second-stage gas separators protect a submersible pump from vapor lock. The pump communicates with the production tubing and is driven by a shaft extending from a motor, through the first- and second-stage gas separators. The first-stage gas separator has a first-stage inlet through the housing in communication with the production fluid from the producing formation. A primary means for separating gas components from the production fluid is in communication with the first-stage inlet and expels separated gas into the annulus through a first-stage gas outlet and advances the liquid component of the production fluid through the first-stage liquid outlet. The second-stage gas separator has a second-stage inlet communicating with the first-stage liquid outlet and leading to a secondary means for separating the gas from the production fluid. The separated gaseous components are expelled through the housing and into the annulus at a second-stage gas outlet while the retained liquid components of the production fluid are presented to the pump, or to additional separation stages, through a second-stage outlet. The production fluid ultimately entering the pump inlet is substantially limited to the liquid components of the production fluid which is pumped through a pump outlet and up the production tubing.

Title: Expandable obturator and catheter assembly including same
Inventor: SOLOMON DONALD D
IPC: A61M25/00
Filed: 1990-06-05
Abstract: An  obturator  includes  a  solid  substantially stiff rod of a nonhydrophilic polymer coated with a layer of a hydrophilic polyurethane which may have an antithrombogenic agent bulk distributed therein.  When the hydrophilic polyurethane comes into contact with an aqueous  liquid such as water,  saline or  a body fluid,  it  absorbs  the  liquid  and  expands  thereby enlarging  the  diameter  of  the  obturator.   Another aspect of the invention is an assembly of a catheter and  the  obturator  of  the  invention.    When  the obturator is emplaced in the catheter and brought into contact  with  a  liquid,  it  expands,  releases  the antithrombogenic agent and contacts the lumen wall of the catheter thereby forming a  seal  which  prevents backflow of a body fluid.

Title: Aqueous foaming composition and method for homogeneously incorporating water into lipophilic materials
Inventor: GIDDEY CLAUDE
IPC: A23L29/10
Filed: 1990-06-27
Abstract: An aqueous foam-forming composition of physiologically acceptable quality having a viscosity not below 5 cP to be used for homogeneously incorporating water to a lipophilic phase. The lipophilic phase is liquefied or ground to a powder and there is incorporated therein by blending a foam of fine air or gas bubbles in the composition, then it is allowed to cool and degas. The foam formation is due to the presence of a foamer, for instance an amphipatic surfactant, and it is stabilized by viscosity enhancers and thickeners. The method is applied to the hydration of chocolate in order to improve its storage stability and heat resistance; the foamer can be selected from esters of fatty acids with polyols.
