Patent CA-2281071-C (CA)
Inventor: THOMAS JOHN E
IPC: D06F34/16
Filed: 1999-08-24
Granted: 2004-04-13
Abstract: According to a method and apparatus for balancing a container using a closed system fluid balance ring for high rotatioal speed washing machines, the transfer of fluid is pulsed, allowing for a variable overall mass transfer rate while computation of the imbalance continues. Mass transfer continues until any significant imbalance is eliminated. The quasi-constant nature of this method allows for the resulting imbalance tolerances to be significantly lower. As the imbalance decreases, the mass transfer rate is varied accordingly.

Patent CA-2310617-C (CA)
Title: Method for the extraction of a substance from a starting material and extraction apparatus for carrying out the method
Inventor: HULLEMAN STEPHAN HENRICK DICK
IPC: B01D11/02
Filed: 1998-11-19
Granted: 2007-03-06
Abstract: The invention relates to a counter-current extraction process with which the starting material to be extracted is conveyed in an extruder through zones of high and low pressure. The zones of high and low pressure can, for example, be formed by different screw elements of opposing pitch. Extractant is fed in in the high pressure zones which are located upstream of the screw elements of opposing pitch. The extractant then flows in counter-current to a discharge opening which is located in or close to the low pressure zone, downstream of a screw element of opposing pitch. With the extraction method according to the present invention a stable counter-current extraction process can be obtained over a very short extraction length and a high extraction yield can be achieved within a short time by intensive mixing of the starting material with the extractant. Furthermore, high pressures ca n be used in the extraction apparatus according to the present invention since the discharge openings are located close to the low pressure zones. As a result the extraction yield is further increased and extraction fluids in supercritical state can be used.

Abstract: An area weapons effect simulation system and method that determine the extent of simulated injuries and damage sustained by players (105) such as soldiers and vehicles as a consequence of simulated mines, projectiles, air defenses, and toxic or nuclear clouds in near real time. The system uses a distributed architecture that simulates the effect that area weapons would have on each player in real time or near real time, thus allowing players to determine the consequences of their tactics and actions as a part of a combat training exercise. Player Units are pre-loaded with information which allows them to determine the probability of damage or injury, depending on the type of player, defensive measures taken on the part of the player, and the type of weapon being simulated. Alternatively, such information may be down-loaded to each Player Unit as necessary.
