Patent CA-2242072-C (CA)
Inventor: ANDERSON CLEO D
IPC: H04B10/02
Filed: 1998-08-07
Granted: 2007-12-18
Abstract: An optical transmission system allows for the remote determination of the output power of each carrier for each repeater. The optical transmission system includes two terminals, an optical path that transmits a plurality of optical signals between the two terminals, and a plurality of repeaters spaced along the optical path. At least one of the terminals generates a first line monitor signal and a second line monitor signal. The second line monitor signal is delayed by a round trip delay from the terminal to a repeater at which the output power is desired to be measured. The terminal then transmits the first line monitor signal on the optical path. Each repeater in the transmission system generates a return line monitor signal in response to receiving the first line monitor signal and transmits the return line monitor signal on the optical path.

Abstract: A process for making detergent agglomerates is provided in which a high acti ve surfactant paste and a detergent builder are agglomerated together. The process entails maintaining the high active surfactant paste in a highly stable, pumpable and transportable form over an extended period of time. In this way, the process facilitates multi-locational, large-scale manufacture of modern compact detergent products. In particular, the high active surfactant  paste can be manufactured in one facility, and thereafter, stored and transported to a remote facility for further processing into the finished detergent agglomerates.

Title: Improved leaching of mineral ores
Inventor: NGUYEN GIAO
IPC: C01G49/14
Filed: 1997-11-06
Granted: 2007-07-03
Abstract: A process for oxidation of ferrous ions in solution, and more particularly a process for improved base metal and/or uranium leaching from ores, concentrates or tailings using ferric ion as an oxidising agent. A reaction vessel (10) holds a ferrous ion-containing solution, for example, a copper sulphide leach slurry or concentrate. An agitator (12) may be provided to promote leaching of the base metal into solu-tion. Some of the ferrous ion-containing solu-tion is drawn off from the reaction vessel (10) and pumped through an in-line mixer (14) via a feed pump (16). Oxygen is injected into the reactor (14) to facilitate oxidation of the fer-rous sulphate to form ferric sulphate. The fer-ric ion-containing solution is then recirculated back to the reaction vessel (10) where the fer-ric ions arc reused in the dissolution of copper sulphide into soluble copper sulphate. The two processes of ferrous oxidation and metal leach-ing can be conducted either simultaneously or sequentially to effect recovery of copper, other base metals or uranium from ores, concentrates or tailings.

Abstract: Disclosed is a method of cleaning endoscopes within a container, wherein fluid flows from inside the container through the endoscope channels, predominantly in one direction, from the smaller-caliber end of an endoscope channel, or lumen, to the larger-caliber end. This method prevents the lodgment of particulate matter and human tissue in the smaller-caliber end of endoscope channels, and it allows fluid to flow through the entire length of all endoscope channels, to permit debris to exit the channels.
Patent CA-2293623-C (CA)
Inventor: JANSSEN WIM
IPC: D21H17/57

Granted: 2007-04-10
Abstract: The invention relates to a method for producing paper, mat, laminate or similar material web using a binder feeding mechanism and by subsequent hardening.      In this method, a water-dilutable acrylate in the form of a binder is fed to the material web at the binder feeding mechanism. The material web is then hardened by an electron beam, after the water content has been evaporated off. After feeding the binder, or after the impregnation process, the material web containing the noncrosslinked acrylate is dried and the water is evaporated from the binder, preferably an emulsion.      The material web is then printed and crosslinkage or polymerization begun. After printing, a varnish is applied that is capable of being hardened by an electron-beam. The material or paper web can be pressure-impregnated with the acrylate.

Title: Chair tilt lock mechanisms
Inventor: MATERN GERALD J
IPC: A47C3/03
Filed: 2000-03-22
Granted: 2009-01-20
Abstract: A chair seat tilt lock mechanism has a detent to latch an actuating lever in a locked and unlocked position. When the lever is moved to a locking position, a spring urges a moveable locking member toward a locking position, however, the moveable locking member only moves to its locking position when the chair is tilted to properly register the moveable locking member with a fixed locking member. When the lever is moved to an unlocking position, another spring urges the moveable locking member to an unlocking position. The moveable locking member may be a slider which slides under a fixed abutment to lock the chair from tilting. Alternatively, the moveable locking member may be a pivoting arm with a series of openings which may receive the forked end of a tongue in a locked position.

Abstract: A room air conditioner (10) of the type having a partition (26), which divides the indoor (12) and outdoor sections (14) of the air conditioning unit (10).  The partition (26) has an exhaust opening for exhausting room air into the outdoor section. A one-piece exhaust actuation device (25) includes an elongated actuating arm. The arm has a first end (120) extending forwardly of the support structure, an intermediate section (122) extending in close proximity to the support structure and through the second opening into the outdoor section. A second end of the actuation device has a curved section (148) configured to extend into the outdoor section (14) in a first direction and to substantially reverse direction with the end of the curved section (148) adjacent to the outdoor section (14) side of the exhaust opening in the partition (26). The end of the curved section carries a door (152) thereupon which is configured to block air flow through the exhaust opening (106) in the partition when it is in confronting relation therewith. Means are provided on the support structure for pivotally supporting the intermediate section (122) of the actuating arm (25) at a position such that lateral movement of the first end (27) of the arm will result in movement of the door (152) selectively between a position in confronting relation with the exhaust opening and a position allowing free exhaust flow through the exhaust opening.

Granted: 2005-12-13
Abstract: A method, computer program, signal transmission, apparatus and system verify instructions in a module of a computer program to be dynamically linked with at least one other module. First it is determined whether checking an instruction in a first module which is loaded requires a lowest upper bound (LUB) class of at least two referenced classes in one or more referenced modules different than the first module. If such information is required, a constraint for the referenced module is written without loading the referenced module. The constraint is of the form "the set of at least two classes inherits from a specified class."

Abstract: The present eye wear is comprised of a pair of lenses, a pair of releasable connectors connected to respective inner ends of the lenses, a pair of temples pivotally connected to respective outer ends of the lenses, and a rigid strap attached between the rear ends of the temples. The strap is positioned below the lenses so as to not interfere with a hairdo or helmet.  The inner ends of the lenses are releasably secured together by the connectors. To wear, the lenses are separated from each other and pivoted outwardly, the strap is wrapped around the back of the head, and the lenses are pivoted toward each other and secured together in front of the eyes. The lenses are instantly separable for easily putting on or taking off the eye wear, but they are instantly connectable together for a secure and accurate fit. In a second embodiment, the strap is comprised of an adjustable-length flexible strap.

Patent CA-2322418-C (CA)
Inventor: BECK PETER
IPC: B30B15/34
Filed: 1999-03-09
Granted: 2004-08-24
Abstract: A double-belt press has a press line in whose downstream section a heat-transfer medium is conducted to forming belts through channels in the supporting plates, the channels running transversely to the panel. This heat- transfer medium is not heated, but rather partially releases its heat in a heat exchanger for use in another assembly. In this way, the heat balance of the installation which includes the double-belt press is improved. The forming belts are supported on roller chains. The roller chains are subdivided in the direction of travel of the panel, thus reducing the transport of heat from the upstream section of the press line to the downstream section.
