Patent CA-2237929-A1 (CA)
Inventor: THOMPSON TIMOTHY
IPC: C12Q1/68
Filed: 1996-11-15
Abstract: The invention relates to methods for the identification of metastatic sequences. Cells from a cell line or an animal tissue are treated to form a cell line predisposed to metastasis. Treated cells are implanted in an animal of a primary site and incubated for a period of time sufficient for the cells to proliferate and develop metastases at secondary sites. Expressed sequences from cells at the primary and secondary sites are amplified by differential display polymerase chain reaction and compared. Differentially expressed sequences are identical and can be cloned and sequenced. These sequences can be used as probes in the diagnosis of metastatic disorders, as probes to isolate metastatic sequences and as a therapeutic agent.
Patent CA-2243746-A1 (CA)
Inventor: MCKENZIE RAY W
IPC: B26D7/26
Filed: 1998-07-22
Abstract: A powered circular saw blade on a vertical shaft is supported on a slide which is slideably mounted on a guideway having feet to enable moving the assembly around on a building sub-floor.  The feet are adjustable to enable raising or lowering the guideway base and, thereby, the saw blade.  A blade guard is affixed to the guideway base and shaped to admit the saw assembly to an inside corner of a building room.  The blade is normally retracted behind the blade guard but can be advanced to position ahead of the guard as the guard is braced against a door jamb or the like and the slide is pushed toward the door jamb to advance the blade into cutting position.  Immediately upon release of the advancing force manually applied, a return spring returns the blade to retracted protected position.

Abstract: The efficiency performances of drill presses have not been improved very much in many years. The acceptance of how things work keeps the mind alienated from any ideas of betterment.This Invention called the Proactive Drill Press Conversion is a betterment of general drill press work. It is an enhancement designed to improve the operation capability of drill presses thus making it safer to operate and more efficient. The betterment of this idea is a one hand control for all the drill press operations via the operating handles: The right hand does the on and off switching, the drilling and the positioning/locking of the drill chuck at any vertical level. The left hand is always and exclusively in control to hold, clamp or move the work piece.      This idea could be made as a kit and sold as such on the market, or it could come completely installed in new drill presses by the manufacturer. Some drill press models may not be suitable for this kit installation and/or may require more work to install. Specific instructions for different drill press models would have to be included with the kit.

Abstract: An isokinetic sampling method has been discovered for use in a pipeline carrying a three phase mixture of petroleum, water and gas. The method is used in combination with a fluid fraction measuring means capable of measuring physical characteristics indicative of fluid fraction. A statistically significant number of samples is analyzed over the range of sampler flow rates. The sampling flow rate is reset to correspond with the flow rate of the maximum standard deviation sample. As a result, samples most representative of the pipeline fluid fraction are withdrawn.
