Patent CA-2398634-C (CA)
Title: Reduced sensitivity melt-cast explosives
Inventor: LUND GARY K
IPC: C06B29/16
Filed: 2000-12-21
Granted: 2008-03-11
Abstract: This melt-cast explosive shares comparable explosive properties to those of COMP B explosives and is melt-pourable and castable under conditions comparable to those of COMP B explosives, but experiences less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with COMP B. A fundamental and well-accepted component of COMP B, i.e., trinitro-toluene (TNT), is replaced with one or more mononitro-substituted or dinitro-substituted melt-cast binders, such as dinitroanisole, which can be melt cast without presenting the toxicity drawbacks experienced with the use of TNT. The melt-cast binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. Preferably, the composition also includes coarse oxidizer particles and energetic filler in fine particulate form.

Title: Forming fabric with machine side layer weft binder yarns
Inventor: STONE RICHARD
IPC: D21F1/00
Filed: 2001-03-06
Granted: 2006-12-19
Abstract: A flat woven papermaker's forming fabric having a paper side layer and a machine side layer interconnected by pairs of machine side layer weft binder yarns. Each binder yarn pair member in sequence interlaces with a portion of the machine side layer warp yarns in segments of the weft yarn path to complete an unbroken weft path in the machine side layer weave pattern, and to provide an internal machine side layer float.      Each binder yarn pair float interweaves with a paper side layer warp yarn to bind the paper and machine side layers together. The location of the internal floats in each layer determines the available interweaving locations, which not all need be used. A wider choice of possible paper and machine side layer weave design combinations is thus made available in forming fabrics, thereby allowing for a better match between the forming fabric and the papermaker's requirements.

Inventor: SHIMURA SATOSHI
IPC: B29C45/18
Filed: 2000-09-06
Granted: 2008-12-23
Abstract: An object of the invention is to provide an injection molding process for preparing thermoplastic resin molded articles and an injection molding apparatus for use in practicing this process, the process and the apparatus being adapted to supply a blowing agent, especially a nonreactive gas such as carbon dioxide or nitrogen gas, to a thermoplastic resin continuously at a relatively low pressure with good stability to incorporate the agent or gas into the resin. As shown in FIG. 3, a resin in a cylinder (2) of an injection molding machine (1) as melted by rotating a screw (3) is mixed and dissolves carbon dioxide which is supplied to the molten resin from a gas supply opening (5) formed in the screw (3). An amount of the gas-incorporating molten resin is measured out and injected into a mold cavity to obtain an expansion-molded article. To incorporate carbon dioxide into the molten resin, the gas is supplied from a gas inlet (11) formed in a rear end portion of the screw to a portion (4a) not fed with the resin and positioned between front and rear screw flights and closer to the front flight, through a gas supply channel 6 extending through the screw and via the supply opening (5).

Abstract: A bus door/service brake interlock system having a warning system is provided to inform a driver that the service brake pressure is insufficient or not being applied at all, as well as indicating if a system malfunction occurs, precluding a service brake application. The system is based on a sequential operation of the driver activating the caution lights and opening the door.  Once these events have occurred, the autobrake system (70) including an alarm (90) is activated. On the other hand, applying the park brake (56) deactivates the autobrake system. The autobrake assembly energizes a solenoid (76) that receives regulated pressure from a pressure reducing valve (72). This pressure is supplied to one side of a double check valve (78), while the other side receives a delivery from the foot valve (24) to assure delivery for normal service braking.

Abstract: La présente invention concerne des procédés permettant de détecter un trouble de prolifération cellulaire associé à TSLC1 (gène suppresseur de tumeur du cancer du poumon), lesquels procédés consistent à mettre en contact une cellule prolifératrice d'un sujet suspecté de présenter le trouble avec un réactif qui détecte TSLC1, et à détecter le niveau de TSLC1 dans la cellule prolifératrice. <I>TSLC1</I> est un gène unique dont l'expression est réduite ou absente dans les lignées cellulaires A549 et dans quelques autres lignées cellulaires de cancers du poumon non à petites cellules, de carcinomes hépatocellulaires et de cancers du pancréas. Il a en outre été découvert que l'expression ou la suppression de TSLC1 est parfaitement corrélée à l'état de méthylation du promoteur. La restauration de l'expression de TSLC1 à des niveaux normaux ou supérieurs à la normale est suffisante en elle-même pour supprimer la formation des tumeurs. L'invention se rapporte également à des procédés permettant de traiter les troubles précités en mettant en contact les cellules d'un patient souffrant de ce trouble avec une quantité thérapeutiquement efficace d'un réactif qui module le niveau de TSLC1 dans les cellules prolifératives.

Abstract: La présente invention concerne un dispositif et un système permettant d'assurer un service clientèle sur Internet, par commande d'explorateur à distance, communication textuelle et liaison audio bidirectionnelle/vidéo unidirectionnelle. Un utilisateur se trouvant à une station de travail de client accède au système par l'intermédiaire d'un réseau, tel qu'Internet. L'utilisateur est ensuite identifié par un gestionnaire de file d'attente. Ce gestionnaire de file d'attente demande à une base de données clients de déterminer quels opérateurs ont précédemment été en communication avec l'utilisateur et la nature des informations précédemment demandées. Le gestionnaire de file d'attente connecte alors l'utilisateur à des opérateurs avec lesquels il a précédemment été en communication. L'utilisateur communique avec les opérateurs en envoyant des informations au moyen de texte, d'audio et/ou vidéo. Généralement, l'émission de signaux vidéo est unidirectionnelle, depuis l'opérateur en direction du client. Lors du temps mort, lorsque l'utilisateur attend un opérateur, le gestionnaire de file d'attente envoie des informations à l'utilisateur sous forme de texte, d'audio et/ou de vidéo relatifs aux informations que l'utilisateur a précédemment demandées. L'appel peut également être transféré d'un opérateur à un autre sur le réseau de données.
