Title: Straddle packer tool for well treating having valving and fluid bypass system
Inventor: OETTLI MARK C
IPC: E21B33/138
Filed: 2002-04-11
Abstract: A straddle packer tool for treatment of wells has a tool body supporting sealing elements in spaced relation for defining a sealed annulus zone within a wellbore. The tool body defines a treatment fluid passage having treatment ports that open to the sealed annulus zone for formation fracturing or other well treatment. The tool body has a bypass passage therethrough which is isolated from the treatment fluid passage and communicates with the wellbore above and below the sealed annulus zone. A check valve permits downward flow of well fluid from the bypass passage into the wellbore below the tool and prevents upward flow of fluid into the bypass passage. Bypass ports conduct fluid flow to and from the bypass passage and the wellbore above and below the sealed annulus zone. A packer actuated bypass valve is opened or closed to control the flow of well fluid within the bypass passage.

Title: Novel enzymes and metabolites involved in skatole metabolism
Inventor: DIAZ GONZALO J
IPC: C12Q1/68
Filed: 2000-09-29
Abstract: Novel metabolites and enzymes involved in skatole metabolism are disclosed. The novel metabolites are 3-OH-3-methylindolenine (HMI); 3-methyloxindole (3MOI); indole-3-carbinol (I-3C); and 2-aminoacetophenone (2-AM). Measuring levels of these metabolites in a pig may be useful in identifying the pig's ability to metabolize skatole and its susceptibility to boar taint. The nove l enzymes involved in skatole metabolism are aldehyde oxidase and CYP2A6. Enhancing the activity of these enzymes may be useful in enhancing skatole metabolism and reducing boar taint. The identification of the enzyme also allows the development of screening assays for substances that interact with  these enzymes and skatole metabolism. Pigs having high levels of these enzym es may be selected and bred to produce pigs that have a lower incidence of boar  taint.

Title: Catheter incorporating an insert molded hub and method of manufacture
Inventor: SARGE JEFFREY A
IPC: B29K77/00
Filed: 2000-11-15
Abstract: A catheter for use in vasculature or other lumens within body structures includes a shaft formed from an elongated polymeric flexible tube. A thin polymeric sleeve is placed over a proximal portion of the catheter shaft. A  hub structure is injection molded over the sleeve with a polymer of the same type as the polymeric sleeve. The heat from the injection molded polymer of the hub body is sufficient to heat the polymeric sleeve, causing the polymeric sleeve to bond the hub body to the sleeve, and the sleeve to the catheter shaft. In this way, the injection molded polymeric hub structure is fused to the catheter shaft, with a unified polymeric bond, and without the use of adhesive. The plastic sleeve is sufficiently thick to protect the catheter shaft from the heat of the injection molded molten polymer while still allowing the catheter shaft and sleeve to bond to the shaft.

Title: Process for preparing blown vegetable oil
Inventor: MAHLUM LARRY
IPC: C11B3/00
Filed: 2001-02-23
Abstract: A method for partially refining a crude vegetable oil utilizing physical refining techniques is described. The crude vegetable oil is first degummed by either (1) allowing the crude oil to settle over a period of time, such as twenty days, so that the oil becomes stratified into at least two layers, wherein one layer comprises gums with low oil content and a second layer comprises oil containing only a fraction of the gums originally present and then separating the oil layer from the gum layer, or (2) heating the crude oil to a temperature of about 270-300°F with agitation and then allowing the crude oil to settle for a period of time until the oil becomes stratified into the at least two layers. The degummed oil is then aerated and agitated while being maintained at a temperature of 170-180°F for a time period sufficient to obtain a desired oil viscosity. The resulting partially refined oil is suitable for use in industrial applications such as the preparation of urethane foams.
