Title: Glass composition for improved refining and method
Inventor: HULME RICHARD
IPC: C03C3/076
Filed: 2006-07-17
Abstract: A soda-lime-silica based glass composition for manufacturing on a float line that has a faster refining rate due to the introduction of alkali earth oxides such as BaO, ZnO and/or SrO in the amount of from about 1-4 wt % in total.  These oxides replace part or all of the MgO in the base glass composition thereby decreasing the overall MgO content in the glass composition to about 2 wt % or less. The glass can realize a lower viscosity at high temperatures so that refining of the melt may occur faster.

Title: Detecting obstructions in enteral/parenteral feeding tubes and automatic removal of clogs therefrom
Inventor: HONARD MARK R
IPC: F04B43/08
Filed: 1999-11-04
Abstract: A tube in a pumped fluid system can become obstructed by a clog. The clog is automatically cleared in response to an obstruction signal (B) by modifying the pumping cycle which is normally used to pump the fluid. In particular, the pumping cycle is stopped after a compression stroke (BDC'-TDC) to apply sustained high pressure in the clogged tube, using the same fluid and the same pump, to expel the clog from the tube. The obstruction signal (B) is derived by measuring the pressure due to viscosity (C) effects have subsided. Therefore, if the pressure remains elevated, a determination of an obstructed state can reliably be made which may be caused by a clog.

Patent CA-2622699-A1 (CA)
Inventor: BROWN WILLIAM D JR
IPC: D21C5/00
Filed: 2006-09-15
Abstract: A method of treating wood chips or saw dust with an enzyme formulation, prior to refining, in order to reduce the total extractives content of the wood chips or sawdust and to modify the wood structure is described herein. The wood chips or sawdust are treated with one or more enzymes such as lipases, esterases, pectinases, cellulases, laccases, hemicellulases and combinations thereof. The enzyme formulation can be applied to the surface of the wood chips or sawdust, e.g. by spraying, or can be impregnated into the wood chips.  The enzyme formulation can further comprise one or more surface active agents which can enhance the effectiveness of the enzyme treatment by improving the diffusion or impregnation of the enzymes into the wood chips. The enzyme-based treatment can be applied at any of several different locations prior to the pulping process including chip piles, chip conveyors, chip silos, chips washers, chip washer water stream, impregnation liquor, or during chip storage. The enzyme-based treatment is quick and easy to apply in most commercial mill operations. The enzyme-based treatment is effective at temperatures from about 20~C to about 100~C, preferably from about 35~C to about 70~C. The wood chips or saw dust can be treated for a period of time from about 0.10 to about 200 hours, more preferably from about 10 to about 72 hours. The addition of the enzyme formulation into the wood chip or sawdust pile increases the concentration of pitch-degrading enzymes on the chip or dust surfaces which can significantly accelerate the degradation of pitch components inside the chips or sawdust. Decreasing the total extractives content of the wood chips and modifying the structure of the wood chips or sawdust leads to a decrease in the apparent pitch content during pulping and in reduced energy requirements, increased paper strength, improved paper machine runability, and lower costs associated with paper manufacturing.

Abstract: A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.

Abstract: L'invention concerne un procédé et un système de coordination de voies autonomes pour un système de distribution sans fil (WDS). Selon l'invention, un système de communication sans fil comprend une pluralité de points d'accès (AP) qui communiquent par l'intermédiaire d'un système de distribution sans fil. Le procédé consiste à établir un groupe de voies coordonnées (CCG) composé d'une pluralité de points d'accès membres. Ces points d'accès membres sont associés à un canal de système de distribution sans fil utilisé pour le système de distribution sans fil parmi les points d'accès membres du groupe de voies coordonnées. Un point d'accès sélectionné parmi les points d'accès membres du groupe de voies coordonnées est désigné comme point d'accès principal. Ce point d'accès principal collabore avec les autres points d'accès membres du groupe de voies coordonnées pour sélectionner et configurer la voie du système de distribution sans fil pour le groupe de voies coordonnées et ajouter et enlever des points d'accès membres. Du fait que les points d'accès peuvent définir un groupe de voies coordonnées, des modifications peuvent être apportées à la voie du système de distribution sans fil de manière autonome, sans que cela n'affecte la connectivité.
