Patent CA-2229064-C (CA)

Abstract: Les coeurs (10, 100) d'un réacteur nucléaire du type à couches fertiles et à germes sont utilisés pour la combustion du combustible thorium avec des combustibles de réacteurs classiques, notamment avec de l'uranium enrichi non prolifératif et du plutonium de qualité militaire ou civile. Selon un premier mode de réalisation, le coeur (10) est entièrement non prolifératif dans la mesure où ni le combustible du réacteur ni les déchets produits ne peuvent être utilisés pour fabriquer des armes nucléaires. Selon un deuxième mode de réalisation, le coeur (100) est utilisé pour assurer la combustion d'importantes quantités de plutonium de qualité militaire avec du thorium; il constitue de ce fait un moyen adéquat de destruction du plutonium de qualité militaire provenant de stocks d'armes nucléaires et de conversion de ce plutonium en énergie électrique. Les coeurs des deux modes de réalisation comprennent une série d'unités à couches fertiles et à germes (12, 102) dont les régions (18, 104) à germes ont une situation centrale et sont entourées de régions annulaires (20, 106) à couches fertiles. Les régions à germes abritent les barres de combustible uranium ou plutonium (22, 110), tandis que les régions à couches fertiles abritent les barres de combustible thorium (26, 118). Les rapports volumiques modérateur/combustible et les dimensions relatives des régions à germes et des régions à couches fertiles sont optimisés afin qu'aucun mode de réalisation ne génère de déchets qui puissent être utilisés pour produire des armes nucléaires. On utilise également, avec le premier mode de réalisation un nouveau système de rechargement qui maximise l'utilisation du combustible à germes et garantit en outre que le combustible épuisé ne peut être utilisé pour fabriquer des armes nucléaires.
Patent CA-2232184-C (CA)

Abstract: Multiple resistance type electric heating elements projecting into the interior of the storage tank portion of an electric water heater are protected against dry firing damage by using a water soluble member, representatively a sugar cube, positioned in the empty tank and blocking the spring-driven movement of a switch closure member that maintains an electrical circuit in an open state preventing electrical  current  flow  through  any  of  the  heating elements.  When the tank is initially filled with water the sugar cube dissolves, thereby unblocking the switch closure member and permitting it to be spring-driven into a circuit closing position to permit electrical current flow through the heating elements.

Title: Receiver for receiving both hdtv and ntsc and method for selecting received signals
Inventor: SHIN HYUN-SOO
IPC: H04N5/44
Filed: 1998-03-30
Granted: 2001-10-30
Abstract: A receiver which receives both HDTV and NTSC signals, and a method for selecting received signals, are provided. According to this method, a broadcasting mode is set from the outside. When the broadcasting mode is an NTSC mode, an NTSC signal is selected. When the broadcasting mode is an HDTV mode, a High-definition (ATV) signal is selected. When the judged broadcasting mode is an automatic mode, it is judged whether an NTSC signal exists in a received signal.If the NTSC signal does not exist in the received signal, said ATV signal is selected. If the NTSC signal exists in the currently-received signal, a channel set from the outside is determined. If the channel is an NTSC channel, the NTSC signal is selected, and if the channel is an HDTV channel, the ATV signal is selected. Therefore, the HDTV and NTSC signals can both be received, and when both NTSC and HDTV signals exist in a channel, one of them can be selectively received.

Title: Video game system and video game memory medium
Inventor: MIYAMOTO SHIGERU
IPC: A63F13/52
Filed: 1998-04-23
Granted: 2006-07-04
Abstract: A video game system including a video game machine and a controller connected thereto, wherein the game machine is further connected with a display device. A video-game memory medium, detachably attached to the game machine, generates image data for displaying a player object, a plurality of courses, and objects other than the player object. A player chooses a course of play by operating the controller. A score-giving condition is detected according to a relation of the player object to another object. Depending on the detection, a first score is counted for the course. When the player object comes under a condition satisfying a course clear, the first score is memorized in a score-register area of a RAM. If the user chooses to play a same course, an initial value is written to the score-register area.

Title: Facsimile-based video compression method and system
Inventor: BERGER TOBY
IPC: H04N7/32
Filed: 1997-02-13
Granted: 2005-06-21
Abstract: A method and system (10) for compressing and decompressing video image data in real time employs thresholding and facsimile-based encoding to eliminate the need for computationally intense two-dimensional transform-based compression techniques. The method operates first by forming a difference frame which contains only information pertaining to the differenc e between a current video image frame and a computed approximation of the video image frame. The difference frame is fed to a thresholder (32) which categorizes each pixel in the frame as being either in a first set having intensities above or at a preset threshold, or a second set having intensiti es below a preset threshold. A facsimile-based compression algorithm in an encoder (44) is then employed to encode the first set of above or at thresho ld pixel locations. To compress the intensity data for each above or at thresho ld pixel, a quantizer (40) and a lossless encoder (50) are preferably employed.

Abstract: Apparatus for feeding and cooking raw product, such as shellfish and the like, in a continuous process. A preferred version of the apparatus includes a feed tank with raw product immersed in a bath. A conveyor follows an inclined path starting in the feed tank and exiting the surface of the bath to convey raw product out of the tank and through a cooking chamber. A feed control mechanism is provided to allow for accurate setting of product flow.  The mechanism includes a rocking paddle extending just above the conveying surface of the conveyor. The paddle is linked to a rotary drive train by a linkage consisting of two pivotally attached arms. Rotation of the drive train causes the paddle to rock and deposit product on the conveyor during each stroke. The drive train is mounted on a slidable support that is pivotally attached to an adjustment rod. The other end of the adjustment rod includes an adjustment handle and a micrometer-style adjustment with clearly visible indicia for adjusting product flow. As the adjustment rod is rotated, the drive train translates and changes the reference angle between the two arms of the linkage, which moves the paddle closer or farther from the conveying surface to adjust the amount of raw product deposited on the belt during each stroke. A cover over the feed tank provides a seal to prevent cooking steam from escaping the cooking chamber through the feed tank.

Abstract: A non-binding reel mount for a harvester platform includes added clearance between the sidewalls of a reel mounting bracket and the reel lifting arms.  Side bushings are provided between the brackets and the arms at the center of the arms to prevent lateral motion of the brackets relative to the arms but enable twisting or rotation of the brackets relative to the arms. The non-binding reel mount thus enables one lift cylinder to be fully extended without causing binding between the reel mounting brackets and the reel support arms during a cylinder charging operation. The reel mount can be designed to provide the desired amount of vertical adjustment to the reel. In an alternative embodiment, a single bushing is provided at the top of the support arm that extends between the two sidewalk of the mounting bracket and wraps around the upper corners of the support arm to prevent lateral shifting while permitting rotation of the mounting bracket on the support arm.
