Patent CA-2252327-A1 (CA)
Inventor: BRADY MICHAEL BARRY CLIVE
IPC: H01J23/20
Filed: 1998-11-03
Abstract: An anode structure for a magnetron includes T-shape anode vanes 3 having a radially extensive component 3a and a circumferentially extensive portion 3b, the cylindrical faces 3c of the circumferential portions 3b facing a cathode in the complete magnetron. The use of T-shape vanes increases inductance and hence permits low frequency radiation to be generated without increasing the dimensions of the magnetron compared to those of a conventional magnetron. Also, capacitance is increased to give a further reduction in frequency by using more than two anode straps, and preferably four anode straps 5 to 8, at each end of the anode structure. Preferably, the anode structure is incorporated in a magnetron in which a high magnetic field of the order of 500 Gauss for a magnetron operating at 100 MHz is used. The anode shell 2 itself may form part of the magnetic return path.

Patent CA-2255153-A1 (CA)
Title: Trailer conveyor adapted for kidney shaped stockpiling
Inventor: LAPPER DEREK
IPC: B65G69/16
Filed: 1998-12-04
Abstract: A good conveyor operator will initially dump material from the lowest height possible.  As the stockpile is created the operator will incrementally raise the conveyor, keeping the discharge end of the conveyor just above the stockpile. Minimizing the height of the free fall of the material from the discharge end of the conveyor minimizes the creation of dust and produces a stockpile having a much more uniform material size distribution.      When a larger kidney shaped stockpile is desired the conveyor is provided with wheels which may be laterally pivoted 90° from a longitudinal travelling position to a radial position wherein the conveyor may be swung around a pivot axis. For safe operation and to efficiently change conveyor height without laterally pivoting the wheels, the conveyor must have a frame which ensures the spacing between the wheels and the pivot axis is generally invariant so that the wheels do not move laterally when the conveyor is elevated.

Title: Apparatus and method for the formation of uniform spherical particles
Inventor: OLSEN KRISTIAN P
IPC: B22F9/06
Filed: 1999-02-19
Abstract: The present invention relates to an atomization apparatus and method for the formation of substantially uniform, at least nearly spherical particles, particularly for the formation of metal particles. The present invention provides an atomization apparatus having a nozzle positioned at the bottom of a cooling chamber. Rayleigh wave instability may be induced by imparting vibrations to a stream of molten material which is released in an upward direction. This produces uniform droplets having an initial velocity sufficient to increase the residence time of the droplets in an inert atmosphere. The parabolic trajectory of the droplets over a 2 m vertical displacement is approximately five times longer than a freefall, thus significantly increasing the cooling time without increasing the cooling chamber height. Further the kinetic energy of each droplet is much lower throughout its trajectory which serves to improve the formation of spherical shaped particles and to lower the impact velocity. Vibrations imparted to the nozzle transversely to the fluid stream cause a periodic dispersion of the sequential droplet trajectories preventing droplets from impacting each other or coalescing.

IPC: G07F7/12
Filed: 1997-11-12
Abstract: A method and system for inhibiting the counterfeiting of electronic cash smart cards (11) that use microchips for monetary stored value. Such cards have recently been counterfeited by the use of electronic techniques to break the security codes. Such counterfeiting can be inhibited by bonding (Fig. 3) an optical memory stripe (17; 41; 74) to the smart card with pre-recorded or post-recorded validation data (19) on the cards (Fig. 1). This optical validation data would be read (Fig. 2) with a photodetector array (65) and could be transmitted to the recipient during funds transfer and/or used locally to control dispensing of cash. Thus, successful counterfeiting of the modified electronic cash card would require meeting exacting electronic and optical requirements.

Patent CA-2288490-A1 (CA)
Inventor: CHEN BYRON HUA
IPC: H04W64/00
Filed: 1999-11-03
Abstract: A local positioning system (LPS) uses the radio propagation parameters in a CDMA forward link or TDMA reverse link to establish a mobile station's position.      The mobile station receives pilot channel signals from at least three distinct base stations and records the PN chip offset of the pilot channel signals. The LPS time difference of arrival triangulation approach requires no additional signal detection capabilities. Base stations send out pilot channel signals that arrive at a mobile station with a particular phase and at least a predetermined minimum strength. The mobile station reports back the "visible" pilot channel signals, their phases and signal strength to the LPS which uses a location non-linear system, expressed as a set of cost functions, to estimate the mobile location. The LPS can also solve the 9-1-1 mobile location problem for wireless CDMA systems by determining the position of a person in distress that has a digital cellular phone.
