Patent CA-2155701-C (CA)
Title: Drying apparatus having rotating vane assemblies and drying method using the same
Inventor: KANAI MASAO
IPC: F26B17/22
Filed: 1995-08-09
Granted: 2001-04-10
Abstract: Disclosed is an improvement in a drying apparatus comprising a cylindrical drying vessel, the inner wall surface of which makes up a heat-transmitting surface, a heat-generating means encircling the cylindrical drying vessel, and at least one rotating vane assembly rotatably fixed in the cylindrical drying vessel.  The rotating vane assembly has vane sections, which leave between their circumferential edges and the heat-transmitting surface of the hollow cylinder an annular space small enough to allow wet material to cross and contact the heat-transmitting surface without falling therein.  Each vane section extends obliquely upward in the direction which is opposite to the rotating direction, and the circumferential edge of each vane section extends less than 360 degrees as viewed from the top.  All vane sections when rotating bear material on their upper surfaces to raise and push material against the heat-transmitting surface under the influence of centrifugal force, thus causing it to continuously climb along the heat-transmitting surface for drying.

Title: Anion releasing apparatus for video appliances
Inventor: JEONG SEOK HWA
IPC: H01T23/00
Filed: 1995-09-14
Granted: 1999-08-24
Abstract: The present invention releases anion out of a main body of an end product, driven by convection caused by heat from heating parts inside the main body. According to this apparatus, anions are released out of the main body by circulating convective air flow caused by heat from heating parts at the lowest part inside the main body. Thus an extra fan and the related circuits are unnecessary.

Abstract: Un système de synthèse de la parole comprend un convertisseur phonologique (10), un analyseur syntaxique (11) de mots, un analyseur syntaxique (12) de syllabes, des éléments d'interprétation temporels et paramétriques (13, 14), un fichier (15) et un synthétiseur (16). L'analyseur syntaxique (11) de mots et l'analyseur (10) de syllabes recoivent un texte d'entrée qui comprend des mots appartenant à une catégorie définie de mots. L'analyseur (11) de mots soumet chaque mot à une analyse syntaxique afin de déterminer s'il appartient à ladite catégorie définie. L'analyseur (11) comprend une base de connaissances contenant les morphèmes individuels utilisés dans la catégorie définie de mots, chaque morphème étant une racine ou un affixe; les caractéristiques de liaison de chaque racine et de chaque affixe, les caractéristiques de chaque affixe définissant également celles de la combinaison de l'affixe et d'un autre affixe ou d'une autre racine; ainsi qu'un ensemble de règles définissant la façon dont les racines et les affixes peuvent être combinés pour former des mots. L'analyseur syntaxique (10) de syllabes détermine les éléments phonologiques des composants de chaque syllables du texte d'entrée. L'analyseur métrique (12) détermine la séquence d'accentuation appliquée aux syllabes de chaque mot. Les éléments d'interprétation temporels et paramétriques (13, 14) interprètent les éléments phonologiques conjointement avec la séquence d'accentuation pour produire une série d'ensembles de valeurs paramétriques permettant de commander le synthétiseur (16). Ce dernier (16) produit une forme d'onde de parole. Les valeurs paramétriques peuvent éventuellement être stockées dans le fichier (15) pour être ultérieurement utilisées.

Abstract: A fabrication process of SOI substrate efficiently removes a non-porous Si region on a porous Si region, and solves the problem that a glass substrate is inevitably etched and the problem that a relatively thick porous Si region is necessary.    The fabrication process of SOI substrate comprises a step of making a surface layer of a single-crystal Si substrate porous to form a porous single-crystal Si region 101 on a first non-porous single-crystal Si region 100, a step of forming a second non-porous single-crystal Si region 102 over a surface of the porous single-crystal Si region, a step of bonding a support substrate 110 through an insulating region 103 to a surface of the second non-porous single-crystal Si region, a step of removing the first non-porous single-crystal Si region 100, and a step of removing the porous single-crystal Si region 101, wherein the step of removing the first non-porous single-crystal Si region 100 comprises a step of performing dry etching in which an etch rate of non-porous single-crystal Si region 100 is greater than that of porous single-crystal Si region 101.

Title: Hydantoin-enhanced halogen efficacy in pulp and paper applications
Inventor: SWEENY PHILIP GERDON
IPC: D21H21/04
Filed: 1995-10-13
Granted: 2002-09-10
Abstract: Free halogen sources (e.g., sodium hypochlorite and chlorine) added as slimicides in high organic component process streams such as pulp and paper processing are rendered more efficacious by the addition of selected N-hydrogen compounds (namely, 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin, cyanuric acid, succinimide, urea, 4,4-dimethyl-2-oxazolidinone, and glycouril) to the process stream. The latter compounds may be added to the process stream before or after the slimicide is added or combined with the slimicide and added directly thereto. The direct use of halogenated hydantoins has also been found to provide improved efficacy relative to free halogen sources. In addition, absorbable organic halogen by-products are reduced.

Abstract: An animal trap comprises a swing frame mounted on a base. The swing frame has a pair of laterally spaced-apart arms and is pivoted to the base for swinging movement from a generally horizontal position to a generally upright position. A spring urges the swing frame to the upright position. A retainer releasably holds the swing frame in the horizontal position. A cable has one end anchored and the other end formed in a loop with the cable extending through the loop to form a noose. Opposite sides of the noose are releasably connected to the arms to hold the noose in an open condition. A baited lure is placed within the noose when the swing frame is horizontal and is operative when pulled by an animal to release the retainer and allow the swing frame to move to its upright position and the noose to snare an animal by the neck and tighten when the animal pulls away.

Abstract: The present invention provides for a process for recovering elemental iron by treating metal oxide fines including oxide therein. The process includes combining the metal oxide fines with a carbonaceous material containing more than about 20 wt% volatile matter to form a mixture. The mixture is agglomerated under conditions sufficient to mobilize the volatile matter to function as a binder that bonds the mixture to form green compacts. The green compacts are heated for a time and at a temperature sufficient to reduce the iron oxide to elemental iron. The carbononaceous material functions as a reductant for the iron oxide.

Abstract: A method is disclosed for establishing a switched virtual circuit in a digital network having network nodes with static routing tables. The static routing tables contain at least primary and alternate routing data. When a node is unable to forward a call over its outgoing primary route due to congestion or physical failure and its alternate route is the same as the route on which a call setup request arrived, it clears the call at that node and sends a crankback message to the preceding node, which responds to the crankback message to attempt to dynamically re-route the call over the alternate route stored in the routing table of the preceding node. If the attempt is unsuccessful, it sends the message back to the next preceding node and so on.
