Patent CA-2091502-A1 (CA)
Inventor: GOSSEL CHRISTIAN
IPC: C10G1/04
Filed: 1993-03-11
Abstract: A process separates a mixture of water, solids or sludges, non-volatile hydrocarbons, and other accompanying substances by means of solvent extraction.  Mixtures that consist primarily of solids or sludge with non-volatile hydrocarbons are especially suited for application of this process, if they occur as a concentrated sludge from a settling pond of bitumen production from tar sands. However, it is also possible to use the process to decontaminate soil contaminated by crude oil spillage.  The process makes it possible to process, and to break down to its primary constituents, the oil-bearing sludge that has accumulated during the production of bitumen from tar sands using the hot water method, and which is stored in settling ponds and constitutes a permanent danger to the environment.  The recycled water is then free of hydrocarbons.  This environmentally compatible process can be carried out with low energy and operation costs.

Patent CA-2099147-A1 (CA)
Inventor: ENGEL KLAUS G
IPC: H01P1/12
Filed: 1993-06-25
Abstract: A radio frequency switch operates by permanent magnets located in a rotatable actuator. The permanent magnets of the actuator are arranged in groups so that there is at least one magnet in each group that has an opposite polarity to another magnet in the same group.  The permanent magnets within the same group are located adjacent to one another. Conductors within an RF cavity have permanent magnets mounted thereon where all of the magnets have the same polarity.  The switch can be moved from a first position to a second position by moving the actuator a distance not exceeding 40° and, preferably from 10° to 30°.  In the first position, one permanent magnet of one group interacts with the magnet on the conductor to move the conductor.  In the second position, another magnet of the same group interacts with the magnet of the conductor to move the conductor.  Since the actuator is moved a relatively short distance, the actuator can be moved by a relatively small step motor or the step motor can be replaced by electromagnets in some embodiments.  The detent required to hold the switch in a particular position can be provided by interaction between the magnets of the actuator and the magnets of the conductor.  The number of groups of magnets and the number of magnets in each group will vary depending on the type of switch.  C-switches, single-pole double-throw switches and T-switches are described.  Previous switches have actuators that move much more than 40° between positions, therefore requiring a larger, heavier and more expensive step motor or other mover.  Also, previous switches cannot switch as quickly from one position to another because of the distance that the actuator must travel.
