Patent CA-2514609-A1 (CA)
Inventor: SORENSEN KURT I
IPC: G01V3/12
Filed: 2004-02-13
Abstract: The invention relates to measuring equipment and method for mapping the geology in an underground formation (2) by means of transient electromagnetic sounding. The measuring equipment (1) comprises a transmitter circuit 4 with a current source for generating an electric current and a transmitter coil (6;  28; 30); a switch for connecting the current source to the transmitter coil during operation so that an electric current is generated in this one, said current builds up a magnetic field in the formation (2), and for cutting off this current again so that the built-up magnetic field in the formation decays; and a receiving circuit with a receiving coil for registering the voltage induced over the receiving coil. By placing the receiving coil (7) in an area (19) where the magnetic field strength is small, the transmitter coils (6; 28; 30) are placed closely above each other, the wire (24; 25) of the transmitter coil (6; 28; 30) is composed of a number of electrically insulated cores (23), and there is a preamplifier (17) for amplifying the registered voltage (Vrcoil) from the receiving coil (7) and the second electrical switch (21) for disconnecting the connection between the receiving coil (7) and the preamplifier (17), a measuring equipment can be provided that is so compact that it can be used for e.g. airborne transient sounding.

Patent CA-2525843-A1 (CA)
Title: Optical fractionation methods and apparatus
Inventor: GRIER DAVID G
IPC: G02B5/18
Filed: 2004-05-14
Abstract: Static arrays of optical traps can be used to sort microscopic objects with exponential sensitivity to size. Such optical fractionation relies on competition between an externally applied force and the moving objects' differing affinities for optical gradient traps. In a reverse fractionation method, objects that are more strongly influenced by the traps tend to become kinetically locked in to the array and are systematically deflected back into an input flow. In a thermal ratcheting method, patterns are spaced to allow particle diffusion, thus providing the opportunity for forward or reverse movement through the patterns. Unlike other sorting techniques, optical fractionation can operate continuously and can be continuously optimized. The exponential sensitivity arises quite generally from the particle size dependence of the potential wells' apparent widths.

Title: Textile net debris trap
Inventor: VAN EDMOND JOHN
IPC: B01D29/27
Filed: 2005-12-28
Abstract: A system of deep well textile based debris traps for storm water polishing before discharge to groundwater recharge wells is disclosed herein. The debris trap is formed by one or capture units, which can fill up relatively in sequence. The debris trap captures coarse sediment and leaves which enter into the well portion of wells and aquifer recharge wells. The traps are designed to capture debris and sediment such as leaves, gravel, and other large debris which would plug filters or aquifer formations.  By building the traps in series these can capture the entire stream flow, each can fill up individually and when full and self closed, can continue to allow substantial flows of water past the individual trap. When used in conjunction with storm water infiltration wells and aquifer recharge wells the debris trap can extend the time between maintenance cycles, increase the time to full cake formation plugging of filters or the aquifer formation

IPC: B01F3/08
Filed: 2006-11-09
Abstract: In one embodiment, a mobile slurry apparatus for creating a slurry from oil sand ore has a frame and a slurry box supported by the frame. Water is mixed with the ore to form a slurry that is retained in the slurry box. The frame base has a first set of spaced apart support points for supporting the frame in a stationary mode, and a second set of spaced apart support points for supporting the frame in a moving mode. The second set of spaced apart support points is closer together than the first set of support points and defines a lifting region disposed beneath a centre of gravity of the slurry apparatus in the moving mode when the slurry box is empty. Thus, a single moving device can be positioned beneath the second set of support points for lifting and moving the slurry apparatus.
