Patent CA-2163181-C (CA)
Inventor: ENGEL JOSEPH CHARLES
IPC: H02H3/00
Filed: 1995-11-17
Granted: 2003-10-07
Abstract: A circuit interrupter samples waveforms in a protected circuit by taking samples in pairs spaced 90 electrical degrees apart. The sum of the squares of samples in each pair, which is representative of the RMS value of the fundamental frequency of the waveform, is used for instantaneous protection by comparing a conning sum of the squares for the two most recent pairs of samples to a threshold representative of the instantaneous trip pick-up value. This sum of the squares of successive two pairs of samples is also used for short delay protection. A delay between successive pairs of samples is varied to produce a selected equivalent sampling rate after a given number of samples. Samples accumulated at this equivalent sampling rate, which is sixty-four samples per cycle in the preferred embodiment, are used for long delay protection and metering.

Title: Video lottery gaming device
Inventor: TRAVIS CHRISTOPHER P
IPC: G07C15/00
Filed: 1995-01-20
Granted: 2003-05-27
Abstract: A video game apparatus (10) includes simulated cylindrical housings (42) that are filled with simulated numbered balls (48) that are apparently mixed by a simulated upflowing stream of air through the cylinders. After the passage of a predetermined amount of time, the mixing stops and a simulated ball (48) having a simulated number appears in a simulated ball trapping member (44, 46) above each cylinder to create the impression that the trapped simulated balls escaped their associated cylinders by riding the simulated upflowing air stream. Mechanical buttons (34, 36, 37) are pressed by a player to select a player's random number, and a random number generator in the game apparatus picks a random number and determines the respective numbers of the balls trapped in the simulated ball trapping members. A monetary award is mechanically dispensed (30) by the apparatus if the random number selected by the player matches the random number generated by the random number generator.

Abstract: A non-woven mat of fibrous thermoplastic insulation is  produced  by  melt  blowing  recycled  polyethylene teraphthalate (PET).  The PET is melted, pressurized and extruded  from  an  extrusion  head  into  substantially continuous fibers that are subjected to turbulent high velocity air that attenuates the fibers.  The fibers are then collected on a collection device building up a non-woven mat.   The collection device is spaced from the extrusion device forming a flight path for the fibers that is sufficiently long that the fibers split apart under the force of  the high velocity  air,  fibrillating  into  a plurality of very fine fibrils of under 15 microns in diameter.  These fibrils are analogous to goose down and greatly enhance the loft and R value of the mat.

Abstract: Temperature compensation method and apparatus for wave meters and tunable lasers controlled thereby which avoids the necessity of maintaining a good vacuum in the wave meter housing and which provides the quick establishment of wavelength accuracy after laser turn on before temperature stability in the wave meter is reached. In accordance with the method, the wave meter housing (12) is filled preferably with one atmosphere of dry nitrogen, and the wave meter output is corrected for temperature effects by combining the uncorrected or raw wave meter output with an appropriate wave meter temperature dependent component (14) and an additional appropriate rate of change of wave meter temperature dependent component (16). The net result is the achievement of accuracy and stability in the wave meter output without use of an oven and before a steady state operating temperature is attained.

Inventor: HAMILTON JAMES R JR
IPC: F25J1/02
Filed: 1998-07-17
Granted: 2001-03-27
Abstract: La présente invention vise un système de commande pour procédé de fabrication de gaz naturel liquéfié (GNL) à partir de gaz naturel à l'aide d'un échangeur de chaleur et un cycle de réfrigération en circuit fermé tirant profit d'une commande directe et indépendante à la fois de la température et de la production par un réglage des paramètres de réfrigération en fonction d'une production définie. Le système de commande règle et commande la production de GNL au rythme de production requis tout en régulant séparément la température du GNL par ajustement des paramètres de réfrigération de la source de gaz naturel. La méthode idéale utilise la vitesse du compresseur, par exemple, comme variable principale (VP) pour assurer une régulation stable et rapide de la température du GNL. D'autres variables du compresseur, l'angle de l'aube directrice dans un compresseur centrifuge ou l'angle de l'aube du stator dans un compresseur axial par exemple, et non pas sa vitesse, peuvent constituer des VP, selon le type de compresseurs à frigorigènes mixtes utilisés. L'autre méthode recommandée utilise un ratio de flux total de frigorigène remis en circulation par rapport au flux de GNL comme variable principale (VP) pour contrôler efficacement la température du GNL.
