Title: Louisiana low
Inventor: BRUNELLE KENNETH J
IPC: A63F3/00
Filed: 1998-03-09
Abstract: A wagering card game is played with a standard fifty-two card poker deck and a count limit card that is permanently assigned as the third card of the dealer's hand.          Each player makes a bet, divides the bet in half and places each half in two separate betting areas on a playing surface.  Two cards are dealt face down to each player and to the dealer.  The players inspect their cards and keep or trade one or both.  If a player trades, he surrenders one-half his total wager.  Replacement cards are dealt face down and the dealer collects the surrendered bets.  After evaluating his hand, each player then places his cards face up in progressive order into card docks provided on the playing surface.  A third card is then dealt face down to each player, but not to the dealer.          The dealer's third card is a count limit card or the representation of a count limit card having a predetermined count value (for example 5) that is imprinted on the count limit card or on the playing surface, and is displayed at all times.          The dealer turns over his cards, combines his dealt cards with his count limit card and states his total.  He then turns over each player's third card one at a time, compares each player's hand with the dealer's hand, determines whether the player is a winner or not and pays or collects on each hand.

Title: Method and apparatus for improved identification of probable defects in a workpiece
Inventor: MCGUIRE MICHAEL
IPC: G01N33/46
Filed: 1998-04-17
Abstract: A method and apparatus for identifying the probable existence and location of defects within a workpiece. The workpiece is preferably wood exhibiting natural variations not the result of defects in the workpiece. The method takes into account the natural variations by segmenting the workpiece into a series of zones. Scanning of the workpiece is performed by an energy source and a detector array. The energy source can be an x-ray source to identify areas of high and low density within the workpiece. For each zone scanned, a long-term average of density is determined. Then for each zone a moving average is determined for localized positions, the moving average being a function of the average of density at the localized position and the long-term average. In this way, regional natural variations in the density of the workpiece bias the long-term average of the workpiece. The method can further include the step of smoothing the raw data with a low pass spatial filter to remove noise and natural variation from the energy source and the detector array. The apparatus includes an energy source, a detector array, and a computer configured to implement the method. The apparatus preferably includes an x-ray device having a plurality of calibration shutters which can be used to perform multi-stage calibration of the detectors and the energy source. The x-ray apparatus further includes collimators having chamfered edges in the apertures.

Patent CA-2256385-A1 (CA)
Inventor: MARTIN JOHN D
IPC: B01D35/153
Filed: 1997-05-23
Abstract: A radial-flow filter (120) employing nonbonded granular particles (56) for filtering impurities from an influent, and that can be backwashed by fluidizing the granular particles (56) to free the impurities therefrom. During a backwashing operation, a backwash liquid applies an upwardly-directed drag force on an upper portion of the granular particles (56) to lift the same into a backwash chamber (62) for fluidization. Once the top portion of the granular particles (56) of the filtration bed is fluidized, the backwash liquid applies an upward force on a subsequent portion of the granular bed, thereby fluidizing the granular particles (56) in the backwash chamber (62). Subsequent sections of the granular bed are fluidized in a similar manner to thereby completely clean the granular particles (56).  After the backwash operation, the granular particles (56) fall back to the filtration chamber (156) and form a filter bed for carrying out a filtration operation.
Patent CA-2258511-A1 (CA)
Inventor: HEANEY PAUL
IPC: C12Q1/68
Filed: 1997-06-13
Abstract: The present invention is a method of sequencing polynucleotides by sequential step sequencing. Sequential step sequencing begins with a single-stranded polynucleotide template that is annealed with a primer forming a primer-template complex. In one embodiment of the method, one labeled nucleotide at a time is added to the primer-template complex. Alternatively, this method can be used with a nucleotide or nucleotide analog that does not stop addition after a first nucleotide or nucleotide analog has been added to the primer.  Other embodiments of the invention involve identification of polynucleotides having a contiguous non-redundant string or a superimposed non-redundant string pattern. The detection of a non-redundant contiguous string can be used to identify a particular gene. Alternatively, if the non-redundant contiguous string is not unique to a particular gene, the string can be used to form a DNA library that can then be searched with a second string. Similarly, a superimposed non-redundant string pattern can be used to identify a gene or to search a DNA library. Such strings can be used in annealing reactions and in computer searches of a database having a catalog of sequenced polynucleotides.

IPC: G01V1/26
Filed: 1999-01-26
Abstract: A system for synchronizing a seismic system having multiple subsystems.    A control system transmits a message to selected subsystems and an internal subsystem counter is zeroed to a selected epoch. Depending on the message or on an internal instruction code, each subsystem initiates an event or sequence of events synchronized to the selected epoch. The system is based on the relative occurrence of cyclic events and does not depend on the transmission of an absolute time signal.   The system is self rectifying, reduces systemic errors, and reduces the data transmission required for system control and operation. The system permits autonomous, asynchronous operation by a subsystem without continuous control by a central controller as a function of time, and can interactively respond to events without intervention from the central controller.
