Patent CA-2389888-A1 (CA)
Inventor: JOHNSON IVOR GILBERT
IPC: A01K61/90
Filed: 2000-11-03
Abstract: A fish grading device (1) is formed from an array of generally rectangular apertures (2), each of which is formed by two long tubes (3) and two short tubes (4) of plastics material mounted to a loop of fishing net (5). Each loop of fishing net (5) is formed by crimping the ends of the loop by means of a metal crimp (6). Each of the tubes (3, 4) can rotate freely about its longitudinal axis, so that a fish brushing against a tube (3, 4) will cause the tube to rotate, and will therefore avoid becoming snagged on the tube. When such a fish grading device (1) is included in a fishing net and the net is dragged through the water, small fish are able to swim through the rectangular apertures (2), whereas larger fish are not. Thus only fish of a desired minimum size are caught.

Patent CA-2394121-A1 (CA)
Inventor: LUKE MIKE A
IPC: E21B21/10
Filed: 2000-10-13
Abstract: The present invention generally provides a system and method for selectively sealing a drill string (14) or other tubular member. In one aspect, a sealing member, such as a valve (50), allows a certain level of flow of drilling fluids and/or other fluids through one or more flow channels (76) when the valve is open. To close the valve, the flow rate is increased so that a backpressure develops and urges the valve to a closed position. The valve can remain in position in the drill string and alternately open (right-hand half of the figure) and close (left-hand half of the figure) depending on the flow rate and/or the pressure drop through the valve. The valve also comprises a removable plug (90) disposed in the valve to provide access with, for example, wireline tools to a region below the valve in a wellbore.

Title: Fluid extraction device
Inventor: COVENTRY FRED
IPC: B67D7/02
Filed: 2002-08-30
Abstract: The present invention provides a fluid extraction device which enables the removal of fluids from a container. The fluid extraction device may potentially minimise the contact between the fluid and the operator attempting to remove the fluid. The fluid extraction device comprises a hollow elongated member through which a fluid is capable of movement; an interconnecting means operatively associated with a first end of the elongated member enabling the attachment of other devices to the fluid extraction device; a retaining means attached to the elongated member for holding the fluid extraction device at a desired position with respect to the container and a filtration mechanism operatively associated with the elongated member for limiting the transfer of particular elements from the container. The retaining means may be positioned at various locations along the length of the hollow elongated member as such that the interconnecting means are removed from the fluid. Once the fluid extraction device is positioned in a container, the fluid may them be removed by connecting a hose to the interconnecting means and activating a pump thereby transferring the fluid from the container to an alternate location.

Title: Multiple input waveguide grating router for broadcast and multicast services
Inventor: LAM CEDRIC F
IPC: H04J14/02
Filed: 2001-04-02
Abstract: An optical telecommunications network suitable for carrying broadcast and switched services. The network includes a wavelength division multiplexing (WDM) coupled to a waveguide grating router (WGR).  In accordance with the invention, an adjacent input port is connected with the same optical content. Thus, its outputs are adjacent (or wrapped around). According, the optical power in each of the broadcast bands at the outputs remains the same but is reduced by a factor of two in power for each channel but occupying twice as many channels. This has the effect of increasing the signal-to-noise ratio (SNR) by a factor of two.

Abstract: Embodiments of a key system for filters and their connecting heads/holders a re shown. The filter cartridge and its holder each have a keyed surface, one being a protruding "key" and one being a recessed "lock". Cooperation of the se keyed surfaces is requied in order for the filter cartridge to be installed in the holder, so that mis-matched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surfa ce of a valve head, or on outer and inner surfaces of connectors that provide a  liquid seal between the filter and the head/holder.

Abstract: An array of dual-element transducers for automated, ultrasonic inspection of a weld seam in austenitic material is configured through the use of a schematic representation of the weld seam. The weld is divided into zones, and separate transducers are selected to inspect each zone. A creep-wave transducer is used to inspect the uppermost zone, and an L-wave transducer is used to inspect a lower zone. The L-wave transducer is connect to a computer processor to serve "double-duty": it is used with one set of gate and gain settings to process direct reflections of the emitted sound, and with another set of gate and gain settings to process indirect, mode-converted reflections of the sound. Gate settings are determined by measuring sound path distances from the schematic.  Test plates are used to determine sensitivity settings, and to confirm adequate width of field for each transducer.

Title: Method to operate a hearing device and arrangement with a hearing device
Inventor: DRTINA PETER
IPC: G01S3/807
Filed: 2003-04-24
Abstract: For the operation of a hearing device having an adjustable transfer function being adjusted by changing a parameter set, a reference person direction is determined in order to ensure that communication between a hearing device user and at least one reference person can take place properly. The reference person direction is defined by the position of the reference person and the hearing device user viewed from the hearing device user. On the basis of the determined reference person direction the transfer function of the hearing device is adjusted by changing the parameter set in such a way that the direction characteristics of the hearing device is aligned with the reference person.   By processing of information regarding direction of a reference person in relation to the hearing device user in the hearing device, the possibility is provided to substantially improve the communication in every day life, in particular in the living area, more particularly between a hearing device user and his fellow occupants. By the present invention, the opportunity is given for a reference person to start and to lead a communication at any time and from any position with the hearing device user, and the reference person is not obliged to change his or her position in such a way that a conversation can be started at all. In particular, reference people having a close relationship to the hearing device user, which reference people have mostly initiated the use of a hearing device, are now confronted with the problem of starting a conversation. With the help of the present invention these circumstances could have been considerably improved.
