Title: Jackpot awarding system
Inventor: DUHAMEL GERALD
IPC: G07F17/32
Filed: 2001-02-23
Abstract: The object of the present invention is a method of awarding prizes, also known as progressive jackpots, in association with a wagering game such as a Poker game. A particular application of this method is in association with a Poker game on an electronic gaming device. For awarding the progressive jackpot, players must accumulate in a counter a number of point corresponding exactly to one of the predetermined criteria. To obtain points, players have only to play the Poker game as on any other Poker machine. The points are added in the counter along with the winning outcomes in the game. A particular embodiment consists of awarding two kinds of points: win points and no-win points. With this embodiment, only win points are effective to win the progressive jackpot.  The no-win points increase the counter values but can not lead to winning the jackpot.

Patent CA-2402658-A1 (CA)
Inventor: KRANTZ K THEODORE
IPC: A44B18/00
Filed: 2001-03-14
Abstract: Fastenings, including stretchy or flexible "zebra-like" and "leopard-like" appearing materials, are disclosed having spaced bands or a distribution islands of molded loop-engageable hooks or molded pre-forms for hooks, betwe en which are bands or regions of different character. Molding is by rigid molds  filled from the base region of the stems. In embodiments, linear bands or islands of fastener elements are themselves inextensible in the direction of  their extent and comprise multiple rows of fastener elements. For ease of forming a uniform, elastically stretchy or flexible product, the bands or islands of fastener elements extend in the machine direction during manufacture. Embodiments shown employ a widthwise continuous carrier of uniform character to which multiple spaced bands or islands of hooks have their molded stems in situ bonded, and in other embodiments, over-lapping margins of the bases of hook bands are in situ laminated to surface structur e of adjacent bands of carrier using a laminating nip in which one of the roll s is a mold roll. For a preferred mode of manufacture of an elastically stretc hy product, stretchy carrier material is stretchy only in the widthwise (cross- machine) direction. In composite hook and loop fastener products, the bands or regions of material between adjacent bands or islands of hooks comprise loop - engageable material, that is uniform in construction widthwise, the loop- forming material itself being an elastically stretchable or a flexible component. In useful product categories, the hook bands or islands and intervening regions of material have importantly different width ranges. Nov el elastically stretchable and flexible loop-defining materials, and their methods of manufacture are shown. In situ lamination of hook, bands or islan ds on surfaces of materials held in a planar orientation or presenting a planar  surface are also shown, flexible materials on tenter frames and rigid materials.

Patent CA-2411107-A1 (CA)
Title: Receiver for determining a mobile object orientation
Inventor: QUEMENER BERTRAND
IPC: G01S5/14
Filed: 2002-03-29
Abstract: The invention concerns the determination of a mobile object orientation using GPS signals. According to the invention, a receiver is provided (16) comprising a single channel assembly for digital processing of signals derived from several antennae (10, 12), said signals reaching the receiver through a single connection (17) which also serves to power antenna preamplifiers and to multiplex at least two antennae. The digital processing channels of the satellite signals use the signals of the antennae to provide phase-locking of a local pseudo-random code, but use only the signals derived from one main antenna (10) to provide phase-locking of a local carrier phase. The phase-shift of the signals between the antennae, which serves to determine the orientation of vectors linking the antennae knowing their relative positions, is calculated from the correlation digital values which conventionally serve in any GPS receiver to establish phase and carrier lock loop signals. The invention is in particular useful for determining a ship's heading. The invention is useful for any type of carrier: pedestrian, land vehicle, ship or aeroplane.

IPC: F25D23/00
Filed: 2001-07-06
Abstract: A cold storage facility (10) energy transfer system has a building (12) whic h includes walls (16), a roof (14), and a floor (18). The building (12) define s an enclosed space, which is to be cooled. A cooling system (30), which includes a compressor (34), a condenser (36), and an evaporator (32), is provided to cool the air within the enclosed space of the building (12). A ground coupled heat transfer mechanism (60) reduces the operating temperatur e of the cooling system (30) and raises the temperature of the building floor (18). A heat exchange mechanism (60) draws heat from the compressor (34) and  the condenser (36) to reduce operating temperature of the condenser (36) and/or compressor. The heat exchange mechanism (60) includes a mechanism (54 ) associated with an area adjacent to the building floor (18) for maintaining that area at a temperature so that underfloor icing is prohibited. An additional objective of the system reduces the temperature of the walls (16)  and roof (14) of the building (12), reducing heat loss and improving the energy efficiency of the building (12).

Patent CA-2422850-A1 (CA)
Title: High citrate dialysate and uses thereof
Inventor: CALLAN ROBIN
IPC: A61M1/16
Filed: 2000-09-22
Abstract: The dose of dialysis in terms of urea clearance is marginal in many hemodialysis patients, and metabolic acidosis as determined by the pre-dialysis serum HCO3 level is common. A dialysate that included citric acid rather than acetic acid as acidifying agent provides superior performance properties. Citrate-containing dialysate was used exclusively in 22 hemodialysis patients. Initially, only 8 of the 22 patients had a pre-dialysis serum HCO3>23mEq/L (lower limit of normal), however, after 12 weeks of dialysis using the citrate-containing dialysate, the serum HCO3 normalized in 15 patients (p=0.0001, Chi-square). Dialysis variables were kept constant in 19 of the patients, who also used and reused the same dialyzer model throughout. In these patients, the initial average urea reduction ratio (URR) was 68.5.plusmn.5.9%, and after treatment with the citrate dialysate disclosed herein, this ratio had increased to 73.plusmn.5.3% (p<0.03). SpKt/V, calculated using the Daugirdas II formula, also increased from 1.23.plusmnØ19 to 1.34.plusmnØ2 (p=0.01). This increased urea clearance may be the result of the anticoagulant property of citrate maintaining patency of the dialyzer membrane. The increase in pre-dialysis serum HCO3 may represent increased delivery from the dialysate and production from citric acid.
