Patent CA-2146860-C (CA)
Inventor: CHOWHAN MASOOD

Granted: 1999-07-06
Abstract: L'invention se rapporte à un procédé amélioré de nettoyage et de désinfection des lentilles de contact à l'aide d'une seule solution. Ce procédé utilise l'effet de nettoyage d'un agent de nettoyage combiné à l'effet solvant de l'eau et à l'agitation physique des lentilles (c'est-à-dire le frottement de celles-ci), ce qui permet d'obtenir un degré de nettoyage comparable ou supérieur à celui des procédés antérieurs, lesquels utilisent des nettoyants contenant des surfactants. L'agent de nettoyage est choisi parmi les polycarboxylates, les polysulfonates et les polyphosphates. L'agent de nettoyage préféré est le citrate. Ce procédé offre également une plus grande commodité par rapport à bien des systèmes antérieurs de nettoyage et de désinfection des lentilles de contact, puisqu'on a supprimé le besoin d'utiliser des produits additionnels pour nettoyer les lentilles.

Abstract: Techniques for reducing the amount of junk e-mail received by a user of an e-mail system. A recipient description containing non-address information is added to an e-mail message. The user has an e-mail filter which has access to information which provides a model of the user. The e-mail filter uses the non-address information and the model information to determine whether the e-mail message should be providedto the user. The e-mail filter further has access to information which provides models of the user's correspondents. If the filter does not provide the message to the user, it uses the non-address information and the model information of the user's correspondents to determine who the message might be forwarded to. A sender of e-mail can also use the model information of the sender's correspondents together with the non-address information to determine who the message should be sent to.The techniques are used in a system for locating exp ertise.

Filed: 1996-05-22
Granted: 2007-11-06
Abstract: A self-contained emergency eye wash station for dispensing eye wash fluid contained in a flexible container comprises a housing, a reservoir, and a platen. The housing supports the flexible container and supports a nozzle in fluid communication with the flexible container. The nozzle dispenses the eye wash fluid from the flexible container. The housing includes a drain capturing the eye wash fluid dispensed from the nozzle. The reservoir collects the eye wash fluid captured by the drain, and the reservoir is slidably mounted to the housing. The platen is connected to the reservoir. The platen is slidably movable relative to the housing and is located immediately above the flexible container. The platen presses downward on the flexible container with a downward force proportional to a weight of the eye wash fluid collected in the reservoir. The transfer of the weight of the eye wash fluid collected in the reservoir to the platen maintains a constant flow of eye wash fluid dispensed from the nozzle.

Abstract: An extrusion apparatus for producing three-dimensional objects comprises at least one die (18, 20), an extruder (12), and a rotatable cutter plate (38).  The die is disposed adjacent to an outlet end of the extruder (12). The die (18, 20) forms an opening defining a two-dimensional shape, and the extruder (12) forces an extrudable material through the opening in the die. The rotatable cutter plate (38) is disposed adjacent to the die. The cutter plate (38) is configured to obstruct different portions of the die opening (14, 16) at different times as the cutter plate (38) rotates so as to vary the shape of the extrudable material forced through the opening (14, 16) in the die and thereby create a three-dimensional shape. The cutter plate (38) is configured to fully obstruct the opening in the die during each revolution of the cutter plate so as to separate the extrudable material forced through the opening in the die into individual objects.

Abstract: In a process for vacuum refining a molten steel wherein a refining flux is used, a fuel gas and an oxygen gas are spouted into the outlet of a top-blown lance of a vacuum refining apparatus to form a burner flame below the top-blown lance, and, at the same time, a refining flux is fed into the top-blown lance with the aid of an oxygen gas as a carrier gas and further passed through the burner flame, and the heated and melted refining flux is allowed to arrive at the surface of the molten steel. In this case, the refining flux feed rate and the circulating flow rate of the molten steel during vacuum refining are regulated so as to have a predetermined relationship, achieving a low flux consumption throughout a period of single refractory life of the vacuum tank.
