Patent CA-2362369-A1 (CA)
Title: Transducer configurations and related method
Inventor: LI GUANG
IPC: G01F1/66
Filed: 2000-02-24
Abstract: A transducer for use in an ultrasonic gas flow meter includes a housing having an open end and a closed end with a side wall extending therebetween.    The closed end of the housing is shaped to receive and transmit sound waves during operation of the transducer. A resonator is positioned in the housing with a transmitting and receiving end facing the closed end of the housing.  A thickness of the side wall of the housing at the closed end is less than at a position further toward the open end in order to divert and diffuse spurious vibrations that might otherwise occur near the resonating frequency of the transducer. Generally, such vibration diversion and diffusion is best achieved when the thickness of the side wall housing gradually decreases toward the closed end of the housing. Further, an outer diameter of the housing side wall may gradually decrease toward the closed end of the housing to improving ringing and bandwidth properties. A method of manufacturing a transducer for operation within a predetermined frequency range is also provided.

Title: Melange de grains de mais eclates et de pastilles
Inventor: SCHILMOELLER LANCE B
IPC: A23L1/18
Filed: 2000-02-07
Abstract: L'invention concerne des amuse-gueule préparés au micro-ondes comprenant un mélange de maïs avec une pastille alimentaire dilatable ou soufflable. Les pastilles sont des pastilles de pâtes à cuisson gélatinées qui gonflent sous l'effet de la chaleur irradiée par un four micro-ondes. Les pastilles se présentent sous forme de cylindres, de barrettes creuses, de sphères, de chips, de flocons et analogues. Le mélange maïs et pastille est de préférence contenu dans un sac expansible ou un tube rigide avec une suspension huile/graisse. Bien que les grains de maïs éclatés nécessitent une période de chauffage plus longue pour être soufflés, les explosions provoquées par les grains de maïs éclatés agitent les pastilles afin de réduire leur épaississement et les risques de brûler.

IPC: G01R29/08
Filed: 2000-04-21
Abstract: Electromagnetic wave source detecting analyzing apparatus and method that can detect and/or analyze a source of (electromagnetic disturbing wave) representing a main factor in generating an electromagnetic field remotely of the apparatus in order to suppress the electromagnetic field intensity at the remote distance from the apparatus to below a regulated value. A magnetic field near an object is measured by a set of probes. A position of an electromagnetic wave source is detected using a phase difference between the two probes. A current distribution on the measured object is determined by solving simultaneous equations containing the position information and magnitudes of measured magnetic fields.      An electromagnetic field at a remote distance from the apparatus is determined from the current distribution to identify the source of the electromagnetic field.

Title: Method of and system for controlling a blasting network
Inventor: DRAGNE LIVIA
IPC: F42D1/05
Filed: 2000-04-20
Abstract: A method and system for controlling a blasting network (16) for use where spurious command signals may be passed through a blasting controller (12) to the blasting network, for example when the controller is connected to the Internet or Intranet (10). The system includes a firewall (14) whereby the communication link (20) between the controller and the blasting network can be placed in a control mode by a switch (19). In the control mode, any previously designated unsafe message such as a fire command is prevented from reaching the blasting network by, for example, disregarding the unsafe message or scrambling it so that it is no longer unsafe. In an operational mode of the communication link, any scrambled unsafe message may be unscrambled and any unsafe message may be transmitted to the blasting network.

Abstract: The invention relates to a screen pipe to be used in dry forming of web material in order to distribute fiber material blown into the screen pipe through a jacket (2) of the pipe onto a wire arranged to move under the pipe.  The fiber material provided inside the screen pipe is made to move for example by means of a spiked roll placed inside the pipe, so that the movement of the fiber material has both a radial and a tangential component with respect to the jacket (2) of the screen pipe. The jacket comprises on its inner surface profiled grooves (8) in the pipe's axial direction. The edge (8a) of the profiled groove is situated downstream with respect to the tangential component of the fiber flow. The upstream edge (8b) of the groove is positioned downstream with respect to the tangential component of the fiber flow. The bottoms of the profiled grooves comprise holes or slots (9) through which the fibers are discharged from the screen pipe. In the invention, the downstream edge (8a) of the profiled grooves is at a more acute angle to the tangential component of the fiber material flow than the upstream edge (8b).

Title: Pai gow poker with tiebreaker cards
Inventor: MCBRIDE SCOTT
IPC: A63F3/00
Filed: 2002-06-27
Abstract: A method of playing a pai gow poker game in which, in addition to the usual seven cards dealt to each player and the dealer, a single player tiebreaker card is dealt for all players and a single dealer tiebreaker card is dealt to the dealer.  The ante bet of each player is then paid off for winning and losing hands in the usual manner of a pai gow game. However, with push hands (where only one of the two-card hand and five-card hand of the player has a higher poker rank than the respective two-card hand and five-card hand of the dealer), the winner is determined by the higher value of the player and dealer tiebreaker cards so that no push bets occur.
