Abstract: A sieve tray column for stripping or recovering metal values from a metal value bearing material includes an elongate column body having an upper end and a lower end and a chamber defined therein. A plurality of spaced apart sieve trays are located within the chamber at intervals between the upper and lower ends. A first inlet is located intermediate the upper and lower ends of the column for introducing a value bearing material, such as a solution or slurry thereof, into the chamber, which value bearing material is arranged to flow in an upwards direction through successive trays towards the upper end. A  second inlet is located at or adjacent the upper end of the column for introducing a resin into the chamber, which resin is fluidised by the upwardly moving value bearing material and caused to flow from one sieve tray to another successive sieve tray towards the lower end of the column. As the resin and the value bearing material contact each other in a counter current manner metal values from the value bearing material are absorbed onto the resin, which metal values can be recovered from the loaded resin.
Patent CA-2439533-A1 (CA)
Inventor: TORRIANI LAURENT
IPC: A61L31/00
Filed: 2002-03-04
Abstract: Pour créer une liaison de forme avec des parties de tissus humains ou animaux, notamment des parties osseuses, on utilise des implants (7) qui sont au moins partiellement constitués d'un matériau liquéfiable par une énergie mécanique. Notamment de tels matériaux adéquats sont des thermoplastiques (p.ex. des thermoplastiques résorbables) ou des matériaux thixotropes. Les implants (7) sont mis en contact avec la partie tissu puis soumis à une énergie d'ultrasons et simultanément pressés sur la partie tissu. A cet effet, le matériau liquéfiable se liquéfie et est appuyé dans les orifices ou les irrégularités de surface de la partie tissu, de telle manière qu'une fois durci, il se lie à ce dernier par liaison de forme. Pour l'implantation, on utilise un dispositif d'implantation qui présente un générateur (2), un élément oscillant et un résonateur (6), le générateur (2) provoquant les oscillations mécaniques de l'élément oscillant qui les transmet au résonateur (6). Le résonateur (6) permet d'appuyer l'implant (7) sur la partie tissu, les oscillations étant ainsi transmises à l'implant (7). Les implants (7) sont, par exemple, en forme de chevilles ou de goupilles et on les utilise à la place de vis pour créer les liaisons avec le tissu osseux qui est éventuellement prépercé pour le positionnement de l'implant (7). L'implantation ne nécessitant pas la transmission de forces de torsion sur l'implant (7), ces implants peuvent être plus faibles, c'est-à-dire plus minces que les vis connues réalisées dans le même matériau. De plus, ces implants peuvent être implantés plus rapidement.

Abstract: An architecture for providing high-speed access over frequency-division multiplexed (FDM) channels allows transmission of ethernet frames and/or oth er data across a cable transmission network (105) or other form of FDM transpor t. The architecture involves downstream and upstream FDM multiplexing technique s to allow contemporaneous, parallel communications across a plurality of frequency channels. Also, the modulation indices of various upstream frequen cy channels may be different, but a plurality of upstream channels may be used to carry a single data flow generally in parallel. The upstream data flow is fragmented into blocks and formed into superframes to allow transmission ove r at least one upstream frequency channels. When a plurality of upstream frequency channels are utilized, the superframes facilitate the possibility of having different modulation indices on the plurality of frequency channels.< /SDOAB>

Title: All-optical switching sites for an agile optical network
Inventor: AGNEW MARTIN
IPC: H04Q11/00
Filed: 2002-09-27
Abstract: An all optical switching site for extending a range and agility of an all optical WDM/DWDM network, by controlling signal intensity balance at each link (11, 11') and performing adaptive dispersion compensation for each dropped channel. The all-optical switching site includes a variable optical attenuator (VOA) (34a, 34b) for each output channel and an adaptive dispersion compensation module (ADCM)(32) in each drop path (24). The VOAs of output channels transported by an output optical fiber link (11') are controlled with downstream feedback to adjust channel signal intensity balance. The ADCM  includes an adaptive controller and a dispersion compensation element adapted to apply a different amount of dispersion compensation to a channel it receives. The adaptive controller receives feedback from a receiver or a signal analyzer, in order to optimize the dispersion compensation. The all-optical switching site reduces network operational cost, improves network reach and significantly enhances network agility.

Patent CA-2465762-A1 (CA)
Inventor: EPPINGER OTTO RICHARD
IPC: B41F15/08
Filed: 2004-04-30
Abstract: A transfer heat press which is intended for use with a rotary screen printing machine, incorporates a C shaped frame mounted on a support and moveable vertically relative to said support. A heater platen is mounted to the top of the C frame. A lower platen adapted to support the pallet of the rotary screen printing machine is mounted on the lower part of the C frame. The lower platen is moveable toward the upper platen. The lower platen applies a force to the underside of the pallet arm of a screen printing machine which results in the platen frame being allowed to move downwardly. This downward movement is guided and cushioned by a pneumatic or hydraulic spring. This arrangement means that the force on the pallet arm is equal to the weight of the platen frame less the upthrust of the pneumatic hydraulic ram. This reduces the risk of damage to the pallet arm.
