Abstract: A retrievable packer for service at high temperatures and pressures has sealing provided by a seal element prop surface (56) of larger diameter than the seal element support surface (48) of a body mandrel (34).  At least one element (30A) of a seal assembly (30) is supported on the prop surface and is subjected to a radial squeeze in the set configuration, even though a lowermost seal element (30C) may be subject to longitudinal separation.  The split level support arrangement provides an annular pocket (62) into which the elements can be retracted upon release of the packer, thereby providing clearance for retrieval.  In releasing the packer, a retainer collar (68) is shifted away from a metal backup shoe (64), thereby providing an annular pocket into which the shoe is deflected, so that it does not obstruct the drift clearance during retrieval. The seal element assembly is preloaded by a cover sleeve (50) which releases when a predetermined compression has been achieved.  The controlled preloading of the seal elements assists movement of the elements to the larger diameter prop surface, and the seal elements are forced to expand into the annulus uniformly to prevent the formation of uneven extrusion gaps.

Abstract: Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered.  The first water addition is to cause the raw wheat grains to have a water content of 12 - 14%.  The tempering of the raw wheat grains is performed for 16 - 36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains.      The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content.  Thus, it is possible to reduce the time required for the tempering of the polished wheat grains and to adjust the second water addition based on the water content in the flour.

Abstract: Les oxydes d'azote émis par un moteur à combustion interne fonctionnant avec un excès d'air sont habituellement convertis selon le procédé de réduction catalytique sélective consistant à mettre en contact les oxydes d'azote avec de l'ammoniac sur un catalyseur sélectif. Dans un véhicule, l'ammoniac doit être transporté uniquement sous forme de substance libérant de l'ammoniac, en général sous forme de solution aqueuse d'urée, en raison des risques liés à l'utilisation d'ammoniac. L'invention vise à empêcher les dégâts causés par le gel aux pièces du dispositif d'épuration des gaz d'échappement pendant les périodes d'arrêt, et vise à permettre le fonctionnement de ce type de dispositif à des températures inférieures au point de congélation de la solution réductrice utilisée. A cet effet, le système (2) comprend un réservoir de stockage (6) (isolé thermiquement) destiné au fluide réducteur (4) ainsi qu'une conduite d'alimentation en fluide (12) raccordée à ce réservoir, ladite conduite débouchant dans une ouverture d'évacuation (22) destinée au fluide (4). Le réservoir de stockage (6) et la conduite d'alimentation en fluide (12) peuvent être chauffés. En outre, un élément chauffant (38) sert à fluidifier un volume initial (14) inférieur au volume du réservoir de stockage (6). La conduite d'alimentation en fluide (12) peut également comporter une soupape de rinçage à contre-courant (20) pouvant être actionnée par un gaz sous pression (30), ce qui permet de nettoyer la conduite d'alimentation en fluide (12) par soufflage.

Title: Fuel vapor control system for internal-combustion engine
Inventor: NOROTA KAZUHIKO
IPC: F02D41/00
Filed: 1996-10-16
Granted: 2002-07-30
Abstract: -25-    A forward flow region in which forward intake air currents are produced and a reverse flow region in which reverse intake air currents are produced are formed in the throttle bore of a throttle body 3 included in an internal-combustion engine, and the boundary between those regions extends below a throttle valve 5. A fuel vapor control system for an internal-combustion engine has a purge tube 13 joined to the throttle body 3 to supply fuel vapor into the throttle body 3 and is provided with an opening 22 which acts as a purge port.  The opening 22 is positioned at a distance from the inner surface 21 of the throttle body 3 defining a throttle bore on the boundary between the forward intake air currents and the reverse intake air currents. Fuel vapor jetted through the opening 22 of the purge tube 13 into the throttle bore flows toward an intake manifold 2, diffusing into both the forward intake air currents and the reverse intake air currents from the boundary between the intake air currents. Accordingly, the fuel vapor is distributed evenly through the intake manifold 2 to the cylinders, so that increase in the difference in air-fuel ratio between the cylinders can be suppressed. The purge port can relatively easily be formed, because the purge tube 13 provided with the purge port is fitted closely in a bore formed in the throttle body 3.

Abstract: An apparatus for continuous ambulatory peritoneal dialysis includes a weighing device secured to a support frame, with a suspending structure for hanging a container of fresh dialysis solution from the weighing device. A further support structure suspends from the same weighing device a container or bag for receiving spent dialysis solution. Three conduits are connected together at respective proximal ends, with one conduit being adapted for connection at its distal end to the fresh dialysate container, a second conduit adapted for connection at its distal end to the container for receiving spent dialysis solution, and the third conduit being a patient conduit adapted for communication at its distal end with a patient catheter through which dialysis solution can both enter and leave the peritoneal cavity. Each of the conduits has its respective clamp for selectively permitting and halting fluid flow through the respective conduit. A central processor is operatively associated with the weighing device, and monitors a signal from that device, the signal representing the weight being supported at any given time by the weighing device. The central processor has data input/output capability by which it can be programmed to carry out a three-stage cycle consisting of a) a fill stage duringwhich the drain conduit is closed, and dialysis solution passes from the container of fresh dialysate through the fill conduit, thence through the patient conduit to the peritoneal cavity of the patient; b) a dwell stage during which the dialysis solution remains in the peritoneal cavity, and c) a drain stage during which the dialysissolution flows from the peritoneal cavity through the patient conduit, thence through the drain conduit to the container for receiving spent dialysis solution. The central processor also includes a real time clock allowing the central processor to track the time taken to fill, the dwell time and the drain time.
