Abstract: A method and apparatus for predicting and controlling secondary kicks, while dealing with a primary kick experienced when drilling an oil and gas well. The method includes a step of determining whether a different pressure per cubic meter of mud pit volume has been caused by a secondary kick by subtracting shut in drill pipe pressure (SIDPP) from shut in casing pressure (SICP) and dividing the derived sum by a kick volume in KPa per cubic meter from the primary kick. A further step is then taken of increasing casing pressure until casing pressure equals pit gain times (X) rate of change in casing pressure per cubic meter of pit gain plus (+) SIDPP.

Inventor: FROETER CRAIG J
IPC: E04D13/04
Filed: 2005-08-12
Abstract: A bi-functional roof drain includes a housing forming a drain manifold and a drain outlet to connect to a drainage system. A vent pipe penetrates the housing and extends through the manifold. The top of the vent pipe is positioned a distance above the housing, which may be variable. With this drain, a method of retrofitting a roof drainage system to provide water drainage and system venting is also presented. This method includes removing an existing uni-functional roof drain from a deck penetration through the roof, and installing a bi-functional roof drain in the same deck penetration. The drain outlet is connected to the drainage system and the vent pipe is connected to the system that requires venting. The height of a top opening of the vent pipe of the bi-functional roof drain may be adjustable in relation to a surface of the roof.

Abstract: A carbonaceous feedstock to alcohol conversion process in which carbon dioxide is removed from the syngas stream issuing from a feedstock reformer, to yield a carbon dioxide depleted syngas stream including hydrogen, carbon monoxide and methane. This carbon dioxide depleted syngas stream is then passed through a Fischer-Tropsch reactor ultimately yielding a mixed alcohol product which is preferably largely ethanol. The removed carbon dioxide stream is passed through a methane reformer along with methane, which is produced in or has passed through a Fischer-Tropsch reactor, to yield primarily carbon monoxide and hydrogen.

Title: Annuloplasty rings for repair of abnormal mitral valves
Inventor: CARPENTIER ALAIN F
IPC: A61F2/24
Filed: 2004-10-01
Abstract: A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a mirror axis, both perpendicular to a blood flow axis.  An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. Viewed another way, the convexity of the P3 segment is less pronounced than the convexity of the P1 segment. In addition, the ring body may have a downwardly deflected portion in the posterior section, preferably within the P2 and P3 segments.  The downwardly deflected portion may have an apex which is the lowest elevation of the ring body and may be offset with respect to the center of the downwardly deflected portion toward the P1 segment. A sewing cuff may have an enlarged radial dimension of between 5-10cm, or only a portion of the sewing cuff may be enlarged.
