Title: Sample dilution module with offset mixing chamber
Inventor: GEBAUER CARL R
IPC: G01N1/00
Filed: 1999-06-15
Abstract: The sample dilution module includes an oil filled aspiration probe and mixing chamber that communicate with each other while the mixing chamber is maintained at an angle of approximately 5 to 45 degrees below a horizontal axis. The aspiration probe is maintained in a vertical orientation. A micro-bubble is aspirated between separate aspirations of test sample and diluent to prevent contact between the sample and diluent in the aspiration probe. The test sample and diluent are then drawn from the vertically oriented aspiration probe into the mixing chamber. After the sample and diluent are in the mixing chamber the micro-bubble of air can migrate away from the test sample and diluent to enable the test sample and diluent to contact each other. Mixing of the test sample and diluent is accomplished by moving the test sample and diluent back and forth in the mixing chamber without physical agitation of the mixing chamber and without any mixing element in the mixing chamber. Such movement is accomplished by alternate suction and vacuum forces imposed on the fluid in the mixing chamber.

Patent CA-2283791-A1 (CA)
Title: Troglitazone compounds for treating climacteric
Inventor: URBAN RANDALL J
IPC: A61L2/02
Filed: 1998-03-03
Abstract: The present invention is directed toward the use of the drug Troglitazone and related thiazolidinedione compounds in the treatment of the climacteric and cancer. This use is based on the novel discovery that Troglitazone inhibits steroidogenesis in granulosa cell cultures. This activity is believed to result from the ability of thiazolidinedione derivatives to act as a ligand for the orphan steroid receptor peroxisome proliferator-activated receptor gamma (PPAR.gamma.). Troglitazone and related compounds can therefore be used to prevent excessive uterine bleeding during. Further, enhanced translocation of this orphan nuclear receptor into the nucleus of cells will block transcription in rapidly proliferating cancer cells that express PPAR.gamma., resulting in loss of cell viability.
Patent CA-2287310-A1 (CA)
Inventor: LARKIN ROBERT FRANCIS
IPC: F16H37/08
Filed: 1998-04-24
Abstract: In a multi-range, continuously variable transmission according to the present invention, input engine power is split between a belt-type, continuously variable transmission unit and a system of interconnected planetary gears. This gear system then combines the split power received from the engine and the transmission unit output to produce a transmission output for propelling a vehicle in multiple forward ranges and one reverse range, each range of continuously variable speed produced by stroking the transmission unit. Synchronous shifting between ranges is achieved by selectively clutching or braking elements of the planetary gear sets at appropriate stroke settings of the transmission unit, such that the vehicle may be smoothly accelerated from rest to maximum speed.

Patent CA-2292153-A1 (CA)
Inventor: XIE JIMIN
IPC: G02B5/28
Filed: 1999-12-15
Abstract: A method and circuit is disclosed wherein two waveguides coupled to an optical resonant ring resonator are further coupled such that beams propagating therein interfere with one another to provide a desired output response. In one embodiment, multiplexed channels of light can be demultiplexed by the device described heretofore, or alternatively, the phase relationship between these two beams can be altered prior to their being combined to provide, for example, a linearized output response useful in applications such as wavelength locking. By varying the reflectivity of the FSR and the coupling ratios and/or by varying the phase relationship between the two beams, a variety of desired output responses can be realized. By providing suitable coupling ratios and providing optical path lengths of the two waveguides which are identical between the ring resonator and the couplers coupling the two waveguides as well as having the couplers placed degrees opposite to each other, an interleaver/de-interleaver function is realized.
