Patent CA-2230631-A1 (CA)
Title: Pipeline pig
Inventor: LUNDIE KEVIN R J
IPC: B08B9/04
Filed: 1998-02-26
Abstract: A pipeline pig has a body with two symmetrical, flexible end portions which give the pig a generally ovate appearance. The end portions are separated by and contain a flexible core. The end portions have a rounded exterior surface and an internal cylindrical cavity. Each cavity has a beveled entry portion for receiving the core. Each end portion also has an outer cleaning area for an abrasive band with teeth for scrubbing a pipeline. Polishing teeth are on an upper portion of the band while coarse teeth are on a lower portion of the band. The core allows the pig to flex as it passes through nonlinear pipeline. The core has a flexible linkage which gives the pig the ability to undergo extensive flexing while maintaining the integrity and strength of the pig. Each end of the linkage receives a bolt which extends through an axial hole in each end portion for fastening the end portions to the core. As the pig moves through pipeline with light build-up, the polishing teeth gently remove it. As the pig moves through pipeline with heavy build-up, the pig is compressed so that the coarse teeth cut and fracture the heavy build-up. When the pig moves back into cleaner pipeline, the pig expands to its original size, thereby allowing the polishing teeth to clean once again. In nonlinear pipeline sections, the pig flexes so that the abrasive bands stay in uniform contact with the inner pipeline wall.

Title: Gas turbine cooling moving blade
Inventor: TOMITA YASUOKI
IPC: F02C7/18
Filed: 1998-03-24
Abstract: The present invention relates to a gas turbine cooling moving blade and is applied to a large-sized blade for a high temperature so as to reduce its thickness and increase cooling efficiency and easily process the moving blade.  A cavity is formed in the interior of the moving blade from the root portion to a shroud at the tip of the moving blade.          Many turbulators are arranged in parallel with each other on an inner wall face of the moving blade.  Cooling air from a turbine rotor enters the cavity formed within the moving blade from a cooling air inlet.  This cooling air is dispersed and disturbed by the turbulators so that heat transfer is improved.  Accordingly, the moving blade is efficiently cooled by the cooling air in comparison with a conventional cooling system having a multiplicity of holes.          The cooling air is then discharged out of a cooling air outlet through air cooling holes of the shroud located at the tip of the moving blade.  Accordingly, the proportion of the hollow space within the moving blade is increased by the cavity and the moving blade is made light in weight.  The moving blade is more easily processed and the cooling efficiency of the moving blade is increased.

Title: Detection of nucleic acid sequence differences using the ligase detection reaction with addressable arrays
Inventor: KEMPE MARIA
IPC: C12Q1/689
Filed: 1997-02-05
Abstract: The present invention describes a method for identifying one or more of a plurality of sequences differing by one or more single base changes, insertions, deletions, or translocations in a plurality of target nucleotide sequences. The method includes a ligation phase, a capture phase, and a detection phase. The ligation phase utilizes a ligation detection reaction between one oligonucleotide probe, which has a target sequence-specific portion and an addressable array-specific portion, and a second oligonucleotide probe, having a target sequence-specific portion and a detectable label. After the ligation phase, the capture phase is carried out by hybridizing the ligated oligonucleotide probes to a solid support with an array of immobilized capture oligonucleotides at least some of which are complementary to the addressable array--specific portion. Following completion of the capture phase, a detection phase is carried out to detect the labels of ligated oligonucleotide probes hybridized to the solid support. The ligation phase can be preceded by an amplification process. The present invention also relates to a kit for practicing this method, a method of forming arrays on solid supports, and the supports themselves.

Title: Substantially linear ethylene/alpha-olefin polymers as viscosity index improvers or gelling agents
Inventor: SCHICKRAM WILLIS CHARLES
IPC: C10M171/04
Filed: 1996-11-01
Abstract: Substantially linear ethylene polymers, such as ethylene/octene copolymers and ethylene/propylene/diene modified polymers, when added in a viscosity modifying amount to an oleaginous material, such as a lubricating oil, provides the material with a viscosity index that exceeds that of the material alone. The substantially linear ethylene polymers, prepared by constrained geometry catalysis, may be grafted with one or more unsaturated organic compounds, such as maleic anhydride, that contain ethylenic unsaturation. The grafted polymer may be further functionalized by reactions with, for example, an alcohol or an amine compound. The substantially linear ethylene polymers, when subjected to shearing action either before or after addition to an oleaginous material, improve shear stability of the oleaginous material. The substantially li near ethylene polymers, whether grafted, grafted and further reacted or not, also work as a thickening agent for compositions such as those used in greases, cable filling coumpounds and cosmetics. In addition, the substantially linear ethylene polymers provide effective results when blended with other components of conventional oleaginous material compositions.

Patent CA-2266118-A1 (CA)
Inventor: HIDDING ROBERT D
IPC: B67D3/00
Filed: 1999-03-18
Abstract: A cap for use with a dispensing system. The cap includes a main outer cap and an inner cap. The main outer cap has a central sleeve which receives and seals against a probe. The inner cap moves into and out of a sealing engagement with the central tube as the bottle is raised and lowered over the probe. The seal between the inner cap and the central tube is located on the outside surface of the central tube. The location of the connection between the inner cap and the probe is displaced away from the location of the connection between the inner cap and the sleeve of the main outer cap. This allows the cap to have effective differentials between the forces which are necessary to achieve proper sequencing of the formation of the various seals and connections which occur during use of the cap.
