Title: Process for producing pentafluoroethane
Inventor: KOHNO SATORU
IPC: C07C17/386
Filed: 1995-05-08
Abstract: There is provided a process of effectively separating pentafluoroethane (HFC-125) out of a mixture of HFC and chloropentafluoroethane (CFC-115). When the mixture of HFC-125 and CFC-115 is subjected to extractive distillation so as to obtain concentrated HFC-125, methanol, ethanol, butanol, propyl alcohol, pentafluoropropanol, tetrafluoropropanol or acetone is used as an extractant, whereby CFC-115 is obtained as a distillate product and a mixture of HFC-125 and the extractant as a bottom product is obtained. Then, the extractant is separated from HFC-125 by distilling the mixture and re-used in the extractive distillation.

Title: Combined slot and table game
Inventor: LOWDEN DAVID
IPC: G07F17/32
Filed: 1997-04-16
Abstract: After a player places an ante wager, a dealer depresses a dealer spin button on a control panel to cause one of a plurality of indicium on respective arc segments of each of two dealer reels of a slot machine to randomly appear on a payline of the machine.          Thereafter, the player may place a combination bet on a prospective appearance of any of a plurality of combinations of indicia on the payline.  Additionally, the player may make a proposition bet on a prospective appearance of a predetermined combination of indicia on the payline.  After the dealer operates a player enable button on the control panel, the player operates a player spin button at a player  station  to  cause  one  of  a  plurality  of  indicium  on respective arc segments of the player reel to randomly appear on the payline.  Thereafter, the ante wager, the combination bet and the proposition bet are reconciled, with the player winning when there  is  a  winning  combination  of  indicia  on  the  payline; otherwise, the player loses.
Patent CA-2202950-A1 (CA)
Title: Circumscribing apparatus
Inventor: TUTTY LARRY
IPC: B43L9/04
Filed: 1997-04-17
Abstract: A circumscribing apparatus for marking a circular reference line about a cylindrical object has a first side. A first frame member has two spaced-apart guide members extending outwardly on the first side of the apparatus. The two guide members fall along a first straight line. A second frame member extends outwardly from the first frame member to a position on a second straight line which is perpendicular to the first line. A scribe is connected to the second member adjacent the position and has a marker extending outwardly on the first side of the apparatus. The apparatus can be used in conjunction with a wrap-around sleeve placed about the cylindrical object. The sleeve has a straight edge which extends about the object along a circular path when the sleeve is fitted. The apparatus is placed against the object with the two spaced-apart guide members contacting the edge. The marker is held against the object at a position spaced-apart outwardly from the edge. The apparatus is moved about the object so the projections stay in contact with the edge and the marker marks a circular line about the object.

Patent CA-2207456-A1 (CA)
Title: Improved client-server architecture using internet and guaranteed quality of service networks for accessing distributed media sources
Inventor: CIVANLAR MEHMET REHA
IPC: H04N21/239
Filed: 1997-06-10
Abstract: An improved client-server architecture of the present invention utilizes the advantages of known QOS networks to provide guaranteed quality of service, security, and a charge mechanism for handling requests initiated over a packet network, such as the Internet, for access to distributed media sources. Such media sources may be independent of the QOS network provider and may be located by browsing the Internet. A method of operating a client-server network enables the system level merger of the Internet and a guaranteed QOS network, such as the public switched telephone network, in order to provide the users with a complete information superhighway today. It will appear to the average user that the Internet and QOS network are fused together. Thus, when a user, connected to the Internet, selects an application that requires functionalities offered by the telephone network, such as guaranteed QOS delivery of media information or customized billing, the Internet-resident application will communicate information to a server, which will in turn initiate a session over the QOS network for delivery of the required information to the client using client information transmitted from the client (or from the application) to the server over the established Internet session. The client information may includea client account number, login and password, and/or phone number to enable the server to establish the switched network connection to the client. Accordingly, media sources which are separate and independent from the QOS network provider may be accessed using a secure, guaranteed QOS network in a manner providing for ease of identification and billing.

Patent CA-2208823-A1 (CA)
Inventor: MERSER N KEITH
IPC: E04B5/00
Filed: 1997-06-25
Abstract: An improved customizable prefabricated truss assembly for floor and ceiling supports having upper and lower elongated fibrous chord members, a central web system supporting the chord members and fibrous end support members located between the chord members adjacent their ends and adhesively bonded to said chord members by an improved polyurethane elastomeric adhesive. The polyurethane elastomeric adhesive is applied to the opposed support faces of the chord members or the end support member end faces preferably in the form of a thin elongated bead having a width less than the width of the surface to which it is applied. In the preferred embodiment, the end support members comprise a plurality of rectangular wood blocks which are adhesively bonded together and to the chord members. The improved adhesive comprises an isocyanate-terminated compound having at least two reactive isocyanate groups and includes from about 3 % to 8 % by weight fumed silica, and a hydroxyl-terminated compound having at least two reactive hydroxyl groups and including from about 3% to 8% by weight fumed silica and from about 10% to 50% by weight filler. Once the adhesive is allowed to cure, the prefabricated truss assembly may be cut to custom lengths to span the supports for the truss members for placement in a floor or ceiling assembly. The trimable end portions of the truss assembly do not include any nails or metal fasteners which would otherwise pose a danger to a worker and potentially damage a cutting tool.

IPC: B01D11/04
Filed: 1996-01-24
Abstract: Procédé de récupération de solvant d'extraction présent dans les effluents aqueux rejetés par un circuit d'extraction au solvant. Selon ledit procédé, les effluents sont mis en contact avec le même diluant non miscible dans l'eau que celui utilisé dans le circuit en tant que solvant pour l'extraction, de manière à ce que le solvant d'extraction passe de la phase d'effluent aqueux à la phase de diluant. Une unité (1) mélangeur-décanteur dotée d'un compartiment (2) de mélange et d'un agitateur (3) peut être utilisée. La phase de diluant, maintenant enrichie d'un solvant d'extraction, est séparée, dans le compartiment (4) de décantation, par exemple de l'effluent aqueux qui est alors épuisé en solvant d'extraction. La phase de diluant séparée peut ensuite être remise en contact avec des effluents ou être combinée à la phase organique du circuit d'extraction au solvant.

Patent CA-2219036-A1 (CA)
Title: Coupling device for locking an excavation tooth onto an adaptor
Inventor: ADAMIC DWIGHT
IPC: E02F9/28
Filed: 1997-11-13
Abstract: The present invention is a coupling device for locking an excavation tooth onto an adaptor. The adaptor and tooth have a passage extending therethrough. The device includes a pin and retainer. The pin is shaped in such a manner as to improve its resiliency and its ability to be disengaged from the retainer to remove the tooth from the adaptor.      The retainer is inserted into the adaptor. The pin includes a retainer seat for engaging the retainer. The retainer seat has a front wall perpendicular to the longitudinal axis of the passage and a back wall which slopes away from the front wall. As the pin is inserted into the passage, the retainer engages the pin until it enters the seat. The front wall then prevents the pin from being retracted from the passage. To remove the pin, force is applied to the driven end of the pin. The pin will continue through the passage while the retainer slides along the sloped back wall of the retainer seat. This arrangement allows for the easy insertion and removal of the pin with a relatively small amount of force.
