Title: Production of granules of reactive metals, for example magnesium and magnesium alloy
Inventor: LAVOIE SERGE
IPC: B22F9/08
Filed: 1995-10-27
Abstract: A process of producing granules of a reactive metal. The process comprises providing a source of molten reactive metal (41), forming discrete droplets (53) of the molten metal, contacting the droplets while still substantially molten with a fluidized bed of particles (12) maintained at a temperature substantially below the solidus temperature of the metal and freezing the droplets as discrete granules of the reactive metal in the fluidized bed. The invention also provides apparatus for carrying out the method and product produced by the method, including a magnesium-containing additive for aluminium alloying. The use of a fluidized bed for cooling and freezing the droplets avoids problems encountered in prior methods and also makes it possible to provide coatings of various kinds on the surfaces of the granules, if desired.
Patent CA-2203043-A1 (CA)
Inventor: BEAUREGARD MARK
IPC: C12N1/20
Filed: 1997-04-18
Abstract: Strains of rumen bacteria are provided which have been genetically altered to express a protein rich in amino acids which are ordinarily deficient in lactating ruminants.   Certain of the modified strains also produce bacteriocin, either naturally or due to genetic modification, which has the effect of improving rumen function, facilitating the establishment of the strain in the rumen and altering the content of unsaturated fat and total fat in milk.   Introduction of these strains into the rumen of ruminant animals can result in the production of milk with a higher protein content, a higher proportion of unsaturated fat and a lower total fat content.

Title: Leg attachment system and method for seats
Inventor: BEURTEAUX KENNETH WILLIAM
IPC: B60N2/90
Filed: 1995-11-15
Abstract: A system to attach seats, in particular rows of light weight seats to the light gauge deck of a high speed passenger marine craft. Horizontal flanges of aluminium angles (23) form a T-shaped foot locking within cavity (35) of track (29) fixed to the deck. High tensile tie straps (27a,b) are held between the vertical webs of the angles (23) by pins (69). A tubular pedestal (25, shown cut in half) has upper recesses (49) which mate with a box beam (not shown) supporting the seats. When the threaded studs (73) of the tie straps (27a,b) are bolted to the box beam, inertial forces arising from the impact of the craft will be uniformly distributed by the pedestal, tie straps and angles (23) to the track for dissipation over an extended length of track thus reducing the effects of localised shear. On assembly of the system, the angles (23) need not be slid along the track but may be inserted individually, being later spaced apart by insertion of tie straps (27a,b) so as to laterally fill the cavity (35).

Inventor: VO THUAN QUANG
IPC: B60R1/00
Filed: 1998-04-15
Abstract: The front view vehicle mirror system (FVVMS) is a mirror assembly mounted on a vehicle to provide vehicle operators with an alternative view of objects ahead that are obstructed by some darken vehicles, such as a tinted car, van, truck, or trailer. The FVVMS includes a plastic or plastic-like case enclosing two periscopic mirrors, one is standard and the other is convex, a solid mounting base attached near a front corner of the vehicle to support and fasten the FVVMS to the vehicle. The FVVMS mounted at the front end on the driver side is particularly useful for the operator to make a safe left turn (in right hand-driving-rule countries) at intersections, and the FVVMS on the passenger side is helpful for the driver to view front objects or road condition ahead when he is trapped in traffic jams or on busy highways. That is, FVVMS provides drivers with an alternative way of observing front objects, while their direct line of sight is blocked by a view obstructing vehicle.

Title: Registration control of mobile stations in a wireless communication system
Inventor: DIACHINA JOHN
IPC: H04Q7/22
Filed: 1996-10-18
Abstract: A method and device are provided for storing and maintaining parameters associated with activities relating to a first channel while a mobile station is camped on or uses a second channel. More specifically, when a parameter indicates that activities are to be executed, the mobile station returns to the first channel to execute the actions associated with the parameter. For instance, parameters associated with a DCCH may be stored when the mobile station moves from the DCCH to a packet data channel (PDCH). When a parameter indicates that activities are to be executed, the mobile station may then return to the DCCH  from the PDCH and execute the actions associated with the parameter. Since the mobile station returns to the DCCH for the actions rather than staying on the PDCH, the mobile station is activated from a system perspective, on both channels.

Patent CA-2238127-A1 (CA)
Inventor: BERGAN TERRY
IPC: G08G1/07
Filed: 1998-05-15
Abstract: Traffic monitoring and warning and vehicle ramp advisory systems are provided herein. They include a first set of sensors comprising a set of electro-acoustic sensors which are disposed above a traffic lane approaching a hazard for producing signals which are indicative of whether the vehicle is an automobile or a truck and, if it is a truck, to record and specify the configuration of the truck. A second set of sensors may be disposed in the traffic lane approaching the hazard for providing signals which are indicative of the speed of a truck traversing the second set of sensors. A  processor is provided which has a memory for storing site-specific data related both to the geometry of the hazard and to signals which have been received from the sets of sensors. A traffic signalling device is associated with the traffic lane and is disposed downstream of the first set of sensors or of the second set of sensors, the traffic signalling device being controlled by the processor. The processor is responsive to the signals from the sensors for computing an actual speed of the truck and for computing a computed maximum speed of the truck. The computed maximum speed of the truck is derived from the site-specific dimensional data and from at least the configuration of the truck, the computed maximum speed of the truck being a maximum speed for the truck of that particular configuration safely to negotiate the hazard. The processor compares the computed actual speed of the truck with the computed maximum safe speed for the truck.  Then, the processor automatically operates the traffic signalling device if the computed actual speed of the truck exceeds the computed maximum speed for the truck. The processor also discontinues operating the traffic signalling device if the computed actual speed of the truck no longer exceeds the computed maximum safe speed for the truck.
