Patent CA-2145370-A1 (CA)
Inventor: HONEGGER WERNER
IPC: B65H29/06
Filed: 1995-03-23
Abstract: A conveying belt is deflected around a stationary deflection roller and loops around the bottom of a deflection wheel. The deflection wheel is freely rotatably mounted on a lever and is prestressed in the direction towards the deflection roller by a spring element. The conveying belt, driven by a stepping motor, and the deflection wheel form a conveying gap for the products, which are arranged in an imbricated formation. In this formation each product, as seen in the feed direction, bears on the preceding product, with almost complete overlapping.        The products form a stack-like supply and are conveyed to the discharge location, with the result that a product is always available there for discharge.

Title: Subscriber telephone diverter switch
Inventor: SOSHEA RICHARD W
IPC: H04L12/56
Filed: 1995-05-08
Abstract: An electronic switch (39) for automatically connecting a subscriber telephone instrument (41) to either of two telephone signal paths is disclosed.  Outbound calls are selectively routed to one or the other of the two telephone signal paths, based on the nature of the initial digits generated by the subscriber.  Local calls are sent to a local exchange carrier (23A) and toll calls are sent to an inter-exchange carrier (25) via a  transmission medium that may also carry other signals, such as cable television or utility energy management signals.  In the event the normal path is out of service, outbound signals are sent  via the  other path.  Inbound signals from either path are automatically routed to the subscriber.  Signal routing is completely transparent to the subscriber.

Abstract: This is absorbent articles such as disposable diapers, incontinent briefs, pull-on diapers, diaper holders and the like, that provide maximized dynamic fit range in the waist opening and improved gasketing action along the leg openings. Side panels (23) extend outwardly from side flaps (37) to provide a wide fit range in the waist opening. The side flaps (37) comprise no elastic for gasketing action and the flaps are relatively narrow. Extended leg cuffs (60) are connectively associated with a chassis (21) along the side flaps (37) so as to provide the gasketing action. Each of the extended leg cuffs (60) has a free distal edge (65) remote from the side flap (37) and a spacing member (67) for spacing the distal edge (65) upwardly away from the absorbent chassis (21). This absorbent article has enough width in the side panels (23) and enough width in the leg openings as needed.

Abstract: L'invention concerne un système de modulation codé par treillis comprenant une source de symboles de données successifs à 2 bits (X¿1?, X¿2?) représentant en structure de trame, chaque trame comprenant une pluralité de segments de données, comportant chacun une pluralité de groupes de symboles de données entrelacés. Chaque groupe de symboles de données entrelacées est codé séparément par un précodeur (32a) et un codeur à convolution (32b) afin de dériver des symboles de sortie codés (Z¿0?, Z¿1?, Z¿2?) qui sont mis en correspondance avec des symboles respectifs à 8 niveaux pour être transmis conjointement avec des symboles de trame générés périodiquement et des symboles de synchronisation de segments. Le signal reçu peut être filtré à l'aide d'un filtre linéaire (42), par exemple un filtre en peigne (42) afin de réduire les phénomères d'interférence dans un même canal, et chaque groupe de symboles filtrés est envoyé à un premier décodeur de Viterbi (44) destiné à estimer les bits de donnée (X¿1?, X¿2?). Chaque premier décodeur (44) comrend de préférence un décodeur de Viterbi (44) à complexité réduite réagissant à une représentation partielle de l'état du filtre linéaire (42). Chaque groupe de symboles reçus peut être également envoyé directement à un second décodeur de Viterbi (46) servant à estimer les bits de données (X¿1?, X¿2?). Les bits de données (X¿1?, X¿2?) estimés envoyés par le premier ou le second décodeur (44 ou 46) sont sélectionnés en vue d'un traitement supplémentaire.

Filed: 1995-03-11
Abstract: Le système comprend une bande transporteuse (7) sur laquelle un dispositif (9) dépose un mélange de frittage en vrac. La bande transporteuse achemine ce mélange à travers une installation d'agglomération par frittage (1) dans la zone d'entrée de laquelle est monté un four d'allumage (3) qui allume la face supérieure du lit de frittage. Un dispositif d'extraction (11) aménagé sous le lit de frittage aspire la zone d'incandescence vers le bas dans le lit de frittage. Dans la zone de sortie de l'installation d'agglomération par frittage (1), en dessous du lit de frittage, il est prévu un second four d'allumage (4) qui allume la face inférieure du lit de frittage. Un second dispositif d'extraction (6) aspire la seconde zone d'incandescence vers le haut. La teneur en substances nocives des gaz brûlés est considérablement réduite, du fait que dans la zone située côté entrée, les constituants non agglomérés par frittage font office de filtre, tandis que, dans la zone située côté sortie, la postcombustion des substances nocives s'effectue dans la zone d'incandescence supérieure. Un adsorbant additionnel permet en outre aux substances nocives de sortir essentiellement dans la zone de sortie de l'installation d'agglomération par frittage.

Abstract: A gas assisted injection molding system and method in which quantity of an inert gas is applied both internally and externally to a thermoplastic material introduced into an injection mold cavity during formation of an injection molded part. The system includes first and second mold portions defining a mold cavity. An injection means injects a quantity of a thermoplastic material into the mold cavity to form an injection molded part within the cavity. At least one internal gas inlet is provided for introducing a first quantity of gas into a portion the thermoplastic material to form a gas channel therein. The gas within the gas channel presses the thermoplastic material against a mold parting line defined by the intersection of the mold portions and forms a seal between the mold cavity and the mold parting line. As least one external gas inlet is located within one of the mold portions for introducing a second quantity of pressurized gas into the cavity to hold the thermoplastic material firmly against an inner surface of one of the mold portions. The system and method of the present invention thereby forms an injection molded part having a sink-free appearance side with a Class A finish.

Title: Two-stage method for preparing polyol fatty acid polyesters
Inventor: MILLER MARK STUART
IPC: C07H1/00
Filed: 1996-11-04
Abstract: A two-stage method for the preparation of polyol fatty acid polyesters is provided. The resulting polyol fatty acid polyesters are very lightly colored (i.e., colorless to slightly yellow) and have a high degree of substitution with fatty acid groups. The first stage of this two-stage method is a solvent-based esterification reaction; the second stage is an essentially solvent-free esterification reaction. In the first stage, a polyol in a solvent (e. g., sucrose in dimethylsulfoxide)) is reacted with fatty acid lower alkyl esters at relatively low temperatures using an alkaline salt catalyst. After the desired degree of esterification is obtained, the resulting partially-esterified polyol fatty acid polyesters and the solvent-containing phase are separated. The separated partially-esterified polyol fatty acid polyesters are further esterified with the same or different fatty acid lower alkyl esters in a second stage with an alkaline salt catalyst using essentially solvent-free, high temperature conditions whereby the degree of substitution is significantly increased. Most of the color bodies and other contaminants capable of producing color are removed with the solvent in the first stage and, therefore, are not present during the higher temperature reaction conditions of the second stage. The resulting polyol fatty acid polyesters, and in particular the sucrose fatty acid polyesters, are especially useful as fat substitutes in food applications and products.
