Patent CA-2548498-A1 (CA)
Inventor: HARWOOD JONATHAN DAVID
IPC: H02P6/08
Filed: 2004-12-21
Abstract: A method and controller for electronically commutating a permanent magnet brushless dc motor (21) under closed loop control where current is commutated (22) through successive combinations of two out of three stator windings to produce a rotating flux. Commutations are determined by each 60~ angular position of the rotor by sensing the back EMF (24) induced in only one of the three stator windings whenever that winding has no applied current flowing in it to determine the 0~ and 180~ positions and extrapolating the 60~, 120~, 240~ and 300~ positions by dividing the time interval therebetween by a factor of 3.

Title: Cell culture system
Inventor: CUVIER ARNAUD ROBERT GILLES
IPC: C12M1/06
Filed: 2004-11-18
Abstract: The present invention provides a novel apparatus to grow cells where the cultivation chamber (1) is partially filled with liquid cultivation medium and cells. Mixing and aeration is achieved by generating intermittently one single large gas bubble (6) at the bottom of the column bioreactor, the single large bubble width representing from 50 to 99 % of the tank width, preferably from 60 to 99 %, more preferably 98,5 %. The culture medium flows out as a film between the large bubble and the inner wall of the bioreactor. This rising bubble allows mixing and aeration of the bulk. As the design of the invention is very simple, it is possible to manufacture it with flexible plastic material and use the apparatus as a disposable system. Moreover, such a mixing/aeration principle minimizes cell damages usually due to shear stress and small bubbles and allows easy and efficient scale-up from small scale to a larger one. Such a large-scale, efficient and disposable culture system can largely reduce production costs.

Title: System and method for monitoring performance of a spraying device
Inventor: WULTEPUTTE LIEVEN
IPC: B67D7/08
Filed: 2006-04-20
Abstract: A spraying device that sprays of a mixture of fluids is monitored to determine whether it is functioning properly. The spraying device has inlets for at least two fluids, such as water and air, and a mixing chamber in which the fluids are mixed. A mixture pressure sensor is mounted on the spraying device to detect the pressure of the mixture. The input pressures of the fluids entering the spraying device are also measured. The measured input pressures of the fluids are used to calculate a predicted mixture pressure based on an empirical formula, which has parameters that can be derived when the spraying device is installed in its operating position. The calculated pressure value and the measured actual mixture pressure are then used in a comparison process to determine whether or not the spraying device is functioning properly.
