Patent CA-2241642-A1 (CA)
Inventor: CROOK RICHARD D
IPC: G07F11/32
Filed: 1998-06-24
Abstract: A vending machine rotor is provided which allows for the holding and subsequent dispensing of two or more bottles from a vending machine.  The vending machine rotor provides a reservoir which comprises at least two bottle locations in which bottles may be loaded and then from which the bottles may be dispensed.  While loaded in the rotor, cut-outs in the rotor enable the necks of at least two of the bottles to overlap by providing recesses in which the outer surfaces of at least two of the bottles may partially radiate outward from the axis of the vending machine rotor.  Finally, a thickened portion of the rotor body may be provided to prevent bottles which exceed a maximum diameter from being used with the rotor of the present invention.

Title: Possibilistic expert systems and process control utilizing fuzzy logic
Inventor: STROBEL STEWART LORNA
IPC: G06N5/04
Filed: 1998-06-25
Abstract: An explicit assumption of continuity is used to generate a fuzzy implication operator, which yields an envelope of possibility for the conclusion. A single fuzzy rule A~B  entails an infinite set of possible hypotheses A'~B' whose degree of consistency with the original rule is a function of the "distance" between A and A' and the "distance" between B  and B'. This distance may be measured geometrically or by set union/intersection. As the distance between A and A' increases, the possibility distribution B* spreads further outside B somewhat like a bell curve, corresponding to common sense reasoning about a continuous process. The manner in which this spreading occurs is controlled by parameters encoding assumptions about (a) the maximum possible rate of change of B' with respect to A' (b) the degree of conservatism or speculativeness desired for the reasoning process (c) the degree to which the process is continuous or chaotic.

Patent CA-2246149-A1 (CA)
Inventor: KOHASHI TAKASHI
IPC: H04B1/707
Filed: 1998-08-27
Abstract: A method of superimposing additional information on a video signal, transmitting it, and detecting the additional information from the transmitted video signal.          The additional information is synchronized with a sync signal in the video signal, and generated in N (N~1) unit intervals of one field of the video signal.   Some predetermined unit intervals of the additional information generated in N (N~1) unit intervals of one field of the video signal, are phase-inverted.  The additional information is identified by detecting the information in unit intervals based on the sync signal in the video signal, and detecting that information in some predetermined unit intervals is inverted.  The additional information is identified by detecting the information in unit intervals, and integrating the detection results with the information in inverted predetermined unit intervals inverted.

Title: Dual-beam contacts having a realignment twist for gang insertion into an insulator housing
Inventor: WEBER DALE A
IPC: H01R12/72
Filed: 1998-09-09
Abstract: A card edge type electrical connector including dual-beam ground contacts each having splayed pre-loaded tips and a realignment twist enabling a plurality of such contacts to be gang inserted into the insulator housing of the connector. To adjust the pitch of the pre-loaded tips, a predetermined twist is added to the bottom of the contacts during the stamping operation which re-aligns the tips with the correct contact receiving apertures. The re-alignment twist disappears once the contact(s) are fully seated in the insulator housing, thus allowing the pre-loaded tips to reach their ultimate position within the insulator housing relative other adjacent contacts.

Patent CA-2250458-A1 (CA)
Title: Telecommunications system
Inventor: SANDERS DAVID GENE
IPC: H04W12/06
Filed: 1997-02-20
Abstract: User data for a telecommunications system (5) is stored at addresses (60a, 60b), etc. in registers (6a, 6b). Each address is accessible for purposes of call-routing, billing etc. by two different user identities; a subscriber identity (IMSI) and a directory number (MSISDN), used respectively by the telecommunications system (5) itself and by users of the system. To allow flexibility of allocation of the user identity types, a translation register (9) is provided which converts MSISDN directory numbers to IMSI subscriber identities, thereby requiring each address (60a, 60b, etc.) in the registers (6a, 6b) to be accessible only by the subscriber identity. This allows a directory number (MSISDN) to be reallocated from one subscriber identity to any other, whether having an address in the same register (6a) or another (6b). This in turn allows subscriber identities (IMSIs) to be permanently allocated to equipment, but transferable between users, increasing flexibility of the system whilst reducing the potential for fraud by "cloning"  (unauthorised reprogramming of equipment to duplicate a subscriber identity).

Title: Dual foot pedal-operated flush toilet
Inventor: FLEMING DAVID CHARLES ROBERT
IPC: E03D1/26
Filed: 1998-10-22
Abstract: A flush toilet for a recreational vehicle has a flush mechanism including a pair of foot pedals, one for opening the bowl outlet closure of the toilet, and the other for opening the flush water valve. Depression of the first foot pedal also depresses the water valve foot pedal, though that pedal can also be operated separately. An actuating cable for the water valve extends through the arm of the bowl closure foot pedal so that, if the water valve foot pedal breaks or is damaged, the water valve can still be opened for rinsing the bowl.
Patent CA-2251771-A1 (CA)

Abstract: The invention relates to a device for transporting flat, especially plate-like, objects (2, 2') with a driven conveyor belt (4, 4') running around a conveyor belt body (3, 3') and on which the objects (2, 2') bear during transport. Said conveyor belt has suction apertures to which a vacuum from a vacuum system can be applied, is to be further developed in such a way that it is possible to convey suspended or supported magnetic and non-magnetic flat, especially plate-like objects at high speeds and considerable acceleration. This is achieved in that the vacuum system is integrated into at least one combined vacuum-magnet system (VMS) which is fitted in the conveyor belt body (3, 3') and its action is applied to the region of the conveyor belt (4,4') bearing the objects (2,2'). Each vacuum-magnet system (VMS) has at least one magnet (5, 5') and one vacuum channel (6,6') connected to a vacuum source (4,4') close to the conveyor belt (4,4'), which is connected to the suction apertures in the conveyor belt (4,4') via suction pipes (7,7') passing through the magnets (5,5').

Title: Pin retainer for ground engaging tools
Inventor: GALE PRESTON L
IPC: F16B21/18
Filed: 1998-10-27
Abstract: A bottom mount pin retainer is disclosed for retaining a mounting pin detachably mounting a first member of a ground engaging tool to a second member thereof. The pin retainer utilizes a retainer assemblage that is adapted to relieve a snap-ring employed for retaining the pin from high axial loads in an upward direction while preventing axial movement of the pin in a downward direction. A non-load bearing member used has sufficient load bearing capacity to restrain the upward movement of the snap-ring during the insertion of the pin into the pin openings in order to seat the snap-ring in its snap-ring groove in the pin.

Title: Apparatus and method for driving recording head for ink-jet printer
Inventor: IKEMOTO YUICHIRO
IPC: B41J2/045
Filed: 1998-11-25
Abstract: An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer are provided for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.
