Patent CA-2315533-A1 (CA)
Title: Heating apparatus
Inventor: SCHMIDT FRANKLIN T
IPC: F23D14/28
Filed: 2000-08-09
Abstract: A heating apparatus for combusting a fuel-air mixture which includes a combustion chamber with an inlet at one end and a combustion outlet at the other end, a catalyst-containing substrate disposed in the combustion chamber, a fuel supply in communication with the inlet for supplying fuel, and a fuel-air mixing assembly for providing a uniform fuel-air mixture to the combustion chamber.  The mixing assembly includes one or more openings for drawing a controlled proportion of primary air which is mixed with the fuel and combusted in the combustion chamber. The use of primary air improves efficiency and reduces the reliance on secondary air.  Limiting the proportion of primary air to approximately 15-20% of the stoichiometric mass of air required substantially reduces the emission of hazardous combustion by-products such as carbon monoxide.

Abstract: A coil handling system, and a method of operating the same, comprises an indexer assembly having a pair of rotatable spindles mounted thereon for supporting a coil of material upon which binding straps are to be placed at predetermined circumferential positions by a strap binding assembly when the rotatable spindles index the coil of material to the predetermined circumferential positions. Upon completion of the strap binding operation, an upender assembly is moved upwardly from a lowered position so as to remove the bound coil of material from the indexer assembly, the indexer assembly is moved to a location remote from the upender assembly so as to permit the upender assembly to be returned to its lowered position with the bound coil of material supported thereon, and the upender assembly is returned to its lowered position at which the upender assembly deposits the bound coil of material upon a conveyor assembly which conveys the bound coil of material to a remote location for further routing or processing prior to commercial distribution.

Title: Method of producing highly pure aluminum primary base metal
Inventor: UCHIDA HIROSHI
IPC: C25C3/06
Filed: 1999-09-09
Abstract: A method for producing a high purity primary metal of aluminum which comprises charging, as a main material, an alumina having been reduced with respect to Si content by a washing treatment with an acid into an electrolytic smelting furnace of Hall-Hercult type, and, in tandem with this, using a deashing coke and/or pitch as a carbon material for an anode. In the washing with an acid, use is made of an aqueous solution of sulfuric acid, an aqueous solution containing sulfuric acid and hydrofluoric acid, or the like, and an acidic aqueous solution warmed up to 40 °C or higher is preferably used for removing Si. The use of this method leads to the production of a high purity primary metal of aluminum having markedly reduced contents of Si and Fe, and thus to the production of a high purity primary metal of aluminum having a purity of 99.95 wt % (3N5) or higher, further of that having a purity near the purity 4N of a secondarily refining metal.

Title: Methode pour realiser en 3d un modele cinematique de deformation d'un bassin sedimentaire
Inventor: CORNU TRISTAN
IPC: G01V11/00
Filed: 2000-10-31
Abstract: Méthode pour réaliser un modèle cinématique prograde permettant de restituer  en 3D des géométries intermédiaires d'objets géologiques d'une zone souterraine telle qu'un bassin sédimentaire, depuis un état initial jusqu'à un état actuel. On forme une représentation de la géométrie actuelle des objets géologiques de la zone par interprétation de données acquises obtenues par exploration sismique, pa r des mesures in situ et par des observations, puis on subdivise chaque objet géologique en couches séparées par des interfaces de déformation (surfaces de contact ou couches ductiles intermédiaires), chacune de ces couches étant discrétisée par un maillage en une série d'éléments de volume hexaédriques. On applique alors séparément et successivement des déformations tectoniques à chaque série d'éléments de volume d'une couche par rapport à une couche sous-jacente avec conservation de l'épaisseur et conservation de l'aire d'une surface neutre intermédiaire dans chaque élémen t de volume, puis on modifie alors itérativement les déformations tectoniques appliquées jusqu'à obtenir une représentation géologique sensiblement en accord avec l'état final connu de la zone souterraine. Par application à un outil de modélisation d'u n type connu, géochimique, thermique ou autre, de données associées à des géométrie s intermédiaires des objets géologiques restituées par le modèle cinématique réalisé, on peut faciliter la localisation dans le sous-sol de zones plus susceptibles d e recéler des fluides.  Applications notamment à la localisation de gisements souterrains.</SDO AB>

Title: Call center queue administration
Inventor: SPENIK JOHN W
IPC: H04M3/51
Filed: 2000-12-13
Abstract: A feature server, e.g., a stored program control-ler, processes calls to a subscriber's main directory number in a packet network by submitting a subscriber-administered questionnaire to callers. The information in the questionnaire, when completed by the calling party, can be used to automatically route the call or to reposition the call in the incoming call queue.      Alternatively, the completed, or even partially     -pleted questionnaire may be displayed in a "pop up" window to a subscriber's operator who can then use the information to assist the caller or, without need of answering the call, to reposition the call within the queue or to divert the call to another directory num-ber. In addition, information previously provided in a questionnaire completed by a caller is stored so that when the caller calls again, the stored information may be employed to more efficiently process the call.
