Patent CA-2327932-A1 (CA)
Title: Method of transporting and delivering substances
Inventor: RUMPH ROBERT
IPC: B01F1/00
Filed: 2000-12-08
Abstract: The invention includes a method of minimizing the delivery cost of a slurry. According to the invention, a mobile tank is incompletely loaded with an at least partially dehydrated component of the slurry. Sufficient room is left in the tank for a diluent to be later added and the slurry constituted in the mobile tank. The incompletely loaded mobile tank is transported to a destination, thereby obviating expense associated with transporting a diluent portion of the slurry. At the destination, diluent is added to the tank and the slurry is constituted by activating a mechanical agitator within the tank.  Slurry is then off-loaded from the mobile tank.

Patent CA-2376747-A1 (CA)
Inventor: BANIASAD PARISA
IPC: A61B5/145
Filed: 2002-03-13
Abstract: An instrument in which NIR light reflects against the skin and the water content correlates with the amount of light absorbed. Water dominates large blocks of the NIR absorption spectra. 1940 nm and 1460 nm were used as measurement wavelengths. A quartz-halogen lamp was used as a light source for the instrument and two band pass filters were used to select the two measurement wavelengths. Laser diodes can also be used. With laser diodes the wavelength is fixed and the light can be chopped by switching the laser diode on and off rapidly. Chopping is a convenient way to synchronise he photo diode (the sensor) with the source. Tests on thin layers of paper show the feasibility of the approach described; for a relatively inexpensive, non-invasive instrument for water content measurement in skin.
