Patent CA-2237477-A1 (CA)
Inventor: WANG HOLMAN
IPC: A47J47/16
Filed: 1998-05-11
Abstract: The present invention relates to a stand for holding cooking pot lids, with two preferred embodiments that function in exactly the same way. The first embodiment comprises a rigid, c-shaped shell which is tapered vertically, forming c-shaped rims of differing diameters at the upper and lower ends of the shell. The second embodiment comprises two horizontal, c-shaped arcs of differing diameters made of tubular metal held at a distance from one another by two rods of tubular metal joining the distal ends of the arcs.      The second embodiment essentially traces the edges of the shell in the first embodiment. The c-shaped rims or arcs form a cradle in which a lid can be placed upside down. Both the larger and the smaller rim or arc can serve either as the cradle or the base for the stand, allowing the stand to be reversed as necessary to accommodate various pot lid sizes and various hand sizes of users.      The tapered design of both embodiments allows multiple stands to be easily stacked for storage and/or shipping.

Abstract: A compressed video playback system which eliminates playback mode transition artifacts. Transitions between various playback modes are effected in such a manner that transition artifacts are eliminated by delaying playback mode transitions until appropriate frames of data are detected for propagation to the compressed video decoder. In addition, compressed video data retrieval methods are improved for supporting multispeed playback modes in both forward and reverse directions in an optimal manner.

Filed: 1996-12-11
Abstract: Dans un procédé permettant de produire des fibres plastiques creuses (20), un polymère fondu est amené à un panier centrifugeur rotatif pour polymère, comportant une paroi périphérique (14). Le panier centrifugeur tourne de façon à faire passer le polymère fondu, par centrifugation, dans un premier conduit (24) traversant la paroi périphérique du panier centrifugeur, afin de former des fibres. On introduit un gaz à l'intérieur du polymère fondu pour former des fibres plastiques creuses. Puis on rassemble celles-ci sous forme d'un produit tel qu'un mat. Les fibres plastiques creuses produites par ce procédé sont des microfibres ayant un diamètre externe moyen compris entre 2,5 et 62,5 microns.
Patent CA-2239291-A1 (CA)
Inventor: BAKER ROBERT
IPC: A23B7/005
Filed: 1996-12-02
Abstract: Method for sterilizing low acid foods using both ultra-high pressures and high temperatures. The instantaneous temperature change that occurs when pressure is applied combines a high-temperature short-time process with ultra-high pressure to deliver a fast and therefore gentle thermal process to a pre-packaged product. The process involves heating a low acid food to a pre-pressurized temperature, subjecting the food to ultra-high pressure, which instantaneously raises the temperature of the food, and then releasing the pressure so that the temperature returns to the original pre-pressurized temperature. The method leverages the adiabatic temperature rise which occurs when the food is hydrostatically pressurized, coupled with the lethality of the pressure, to achieve appropriate sterilization conditions. The disclosure also includes low acid foods which have been sterilized using both ultra-high pressures and high temperatures.

Title: Terminal pin structure of resolver
Inventor: OHSHITA HIROMI
IPC: H02K3/38
Filed: 1998-06-24
Abstract: A terminal pin structure of a resolver having a plastic body for holding terminal pins to which a lead wire is connected is mounted on an undercover.  The undercover is connected to the end of a stator and coils connected to projecting portions of terminal pins extending from the plastic body.  With this arrangement, dispersed soldering of coils to a lead wire which conventionally arises when the coils are directly soldered to the lead wire by a manual operation can be eliminated and thus, soldering can be easily carried out, variability in quality can be eliminated and operability can be improved.

Title: Dispositif et procede de surveillance et de commande en temps reel de la sterilisation d'une charge et liberation parametrique
Inventor: PAI SANJEETH M
IPC: A61L2/26
Filed: 1997-02-11
Abstract: Ce dispositif et ce procédé permettent de surveiller et commander en temps réel des paramètres d'un cycle de stérilisation dans un dispositif de simulation de charge qui reproduit les conditions régnant dans une charge d'essai normalisée acceptable à stériliser. L'intégration de ce dispositif dans le système de commande de stérilisation permet d'obtenir et de maintenir dans la charge simulée, tout au long d'un cycle de stérilisation, des niveaux critiques de paramètres de stérilisation, ce qui entraîne une réduction significative du nombre de cycles défectueux. Un système redondant de surveillance de paramètres est inclus dans ce dispositif. Quand des niveaux acceptables de paramètres de stérilisation sont dûment atteints, les charges stériles sont automatiquement libérées et utilisables dès l'achèvement du cycle, ce qui évite le recours à des indicateurs biologiques et à des intégrateurs chimiques.

Title: Bridging agent for laminates and method of using same
Inventor: CHOU YING-CHENG
IPC: B32B7/10
Filed: 1998-10-19
Abstract: A bridging agent for improving the bond between incompatible component layers of laminates comprising one or more N-substituted melamine compounds. The bridging agent is comprised of an N-substituted melamine, an N-substituted melamine formaldehyde resin, a hybrid of an N-substituted resin, or mixtures of these resins. The bridging agent improves bonding between laminate layers known not to bond well together such as between a styrenated polyester top coat and a melamine impregnating resin. As a result of improving the bond between the incompatible component layers, the bridging agent improves the blister resistance and cove forming characteristics of the laminate. The bridging agent can be used to improve bonding both with and without a trans paper layer.

Title: Regenerative oxygen preheat process for oxy-fuel fired furnaces
Inventor: KOBAYASHI HISASHI
IPC: F23L15/02
Filed: 1999-01-04
Abstract: A method and apparatus for supplying oxygen to an oxy-fuel fired furnace that has been preheated by heated flue gas recycled from the furnace. One or more regenerators are provided each having at least a first and a second regenerator bed. The beds are alternately cycled so that one is being preheated with hot flue gas exhausted from the furnace while the other is preheating oxygen through its already heated bed for supply to the furnace burner. The amount of hot flue gas supplied to the regenerator beds is controlled by continuously venting a portion of the total furnace flue gas so as to bypass the regenerators, and the regenerator beds are purged of residual oxygen by recycled cooled flue gas which is then supplied to the furnace before the regenerator beds are heated by the flue gas.

Title: Method of producing reduced iron agglomerates
Inventor: HARADA TAKAO
IPC: C21B13/10
Filed: 1999-03-23
Abstract: Iron oxide agglomerates incorporated with the carbonaceous material having a particle size within a range of about 10 to 30 mm are prepared upon production of reduced iron agglomerates. Then, the iron oxide agglomerates incorporated with the carbonaceous material were laid thinly at a laying density of less than 1.4 kg/m2/mm or lower on a hearth of a moving hearth furnace. Subsequently, the iron oxide agglomerates are heated rapidly such that the surface temperature of the iron oxide agglomerates reaches 1200°C or higher within one-thud of the retention period of time of the iron oxide agglomerates in the moving hearth furnace. Then, the iron oxide agglomerates are reduced till the metallization ratio thereof reaches 85% or higher to form reduced iron agglomerates and then the reduced iron agglomerates are discharged out of the moving hearth furnace. With the procedures, reduced iron agglomerates of a high average quality can be obtained at a high productivity.
