Patent CA-2235728-A1 (CA)
Title: Lame tranchante permettant de decouper des materiaux en feuille
Inventor: FRANK ARMIN C
IPC: B26F3/02
Filed: 1996-11-27
Abstract: Lame tranchante (30) permettant de découper des matériaux en feuille tels que film plastique ou feuille métallique. La lame tranchante (30) comporte une rangée de dents coupantes (50) formant saillie par rapport à une surface plate. La profondeur de coupe de la lame (30) est limitée par la hauteur de la saillie que la dent coupante (50) forme par rapport à la surface plate. De plus, l'espacement des dents coupantes (50) est suffisamment resserré pour que ces dents coupantes (50) forment une surface d'appui suffisante pour servir de support à la peau humaine. Ainsi, la lame (30) découpe le film plastique et la feuille métallique mais n'entame pas facilement la peau humaine.

IPC: D06L4/60
Filed: 1998-09-03
Abstract: Plastic articles, especially plastic optical lenses are tinted by immersing the plastic article in an aqueous dispersion of tinting agent and exposing the dispersion and immersed article to microwave radiation to bring the dispersion to ebullition; the ebullition is maintained for at least 2 seconds with transfer of tinting agent from the dispersion to the article to tint the article; the tinted article is removed from the dispersion and rinsed with water. The method achieves tinting in significantly shorter times than conventional methods and employs water-based dispersions thereby avoiding emission of vapors of organic solvents.

Title: Arrangement for equalizing levels of service among skills
Inventor: MATHEWS EUGENE P
IPC: H04M3/42
Filed: 1998-10-28
Abstract: In a skills-based ACD, an available agent is reserved and assigned to handle calls needing a "rare" skill of the agent and is prevented from handling calls needing a "common" skill of the agent even if calls needing the common skill are waiting to be handled, if not reserving the agent for the calls needing the rare skill would deprive those calls of the last available agent, even if no calls needing the rare skill are available for handling. The agent is reserved only if target performance criteria, such as average speed of answer, for handling the calls needing the common skill are being met. In case of more than one agent being available to handle calls that need the rare skills, one of these agents is selected and reserved and the other agents are freed to serve calls needing "common" skills.

Title: Sun protection installation comprising sun protection lamellae having a toothed upper side
Inventor: KOESTER HELMUT
IPC: E06B9/386
Filed: 1998-12-08
Abstract: The invention relates to sun protection installations comprising reflective sun protection lamellae consisting of portions having a toothed upper side disposed at least towards sun radiation influx wherein the individual teeth are formed of at least two tooth sides, and at least one first tooth side is, at least partly, exposed to sun light irradiation. Sun light irradiation, at least within the first lamella portions, can be retro-reflected by one single reflection into the outer space by the first tooth side having an angle of impact .alpha.1. The tooth angle of impact .alpha.1 of the tooth sides exposed to the sun light are so selected within the first lamella portions facing the irradiation area that in case of parallel sun light larger angles of impact .beta. of the sun radiation are obtained so that inciding sun light may be reflected back, by one single reflection, to the outer space.  Second or further lamella portions are so arranged at an angle .alpha.1 that small angles of impact .beta. on the tooth sides facing the sun will result but the sun light can be reflected into the interior space. In any case, tooth angles of impact .alpha.1 within the lamellae differ from each other.

Title: Method of remediation of contaminants in porous media through minimization of buoyancy effects
Inventor: POPE GARY A
IPC: B01D12/00
Filed: 1997-11-05
Abstract: A method for controlling vertical migration of contaminants in an aquifer includes introduction of a solubilizing solution having a surfactant and an alcohol or other light co-solvent. The surfactant is selected to solubilize the contaminant. The alcohol or other solvent is selected to provide the microemulsion with a substantially neutral buoyance with respect to groundwater. The neutral buyoancy of the microemulsion prevents the normal downward movement which is typical of the solubilized dense non-aqueous phase liquid in surfactant-enhanced a quifer remediation. Thus, the risk that any significant amount of solubilized dense non-aqueous contaminants will migrate vertically can be controlled. The relative tendency for vertical migration may also be reduced by increasing the injection rate or injected fluid viscosity by adding polymer or reducing the well (120, 130) spacing.
