Abstract: The valve element for attachment to a flexible bag may include one or more flexible layers intended to extend over a hole disposed through a sidewall of the bag. In its normal condition, the layer or layers are in adjacent contact to each other or to the bag sidewall and thereby cover and seal the hole.  During evacuation, the layer or layers displace to provide a collapsible and expandable channel that allows air to move from the hole to an exit point. To facilitate sealing of the valve element, a tacky surface is included in the valve element. The tacky surface can have a tackiness quality that normally holds the layers and / or sidewall together but that can be overcome during evacuation to expand the channel.

Abstract: The present invention relates to an electronic ballast for operating a lamp (L) which has a Class E converter (T1, L1). When a lamp (L) is connected, the output current of the Class E converter (T1, L1) once a switching element (T1) of the Class E converter (T1, L1) has been switched off has a first and a second half-cycle of opposite polarity. The electronic ballast has a measurement apparatus for measuring the output current and a regulating apparatus for adjusting a switch-on time of the switching element. In this case, the measurement apparatus is designed to determine a first output current value of the first half-cycle and a second output current value of the second half-cycle, wherein the regulating apparatus for adjusting the switch-on time is fed a control variable based on the discrepancy between the two output current values.

Abstract: A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels associated with uplink and downlink communications, between the first cell region and at least a second cell region. The invention has a particular advantage in time division duplex (TDD) mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.
Patent CA-2645382-A1 (CA)
Inventor: TROLIN DANIEL
IPC: D21C1/02
Filed: 2008-11-27
Abstract: The invention concerns an arrangement and a method for the steam pre--treatment of chips during the production of cellulose pulp. With the aim of avoiding the blow-through of gases in the steam pre-treatment vessel (1) and in this way preventing foul-smelling gases from being released into the atmosphere, spreader nozzles (10) for the injection of cooling fluid are arranged in the gas phase of the steam pre-treatment vessel. In the event of the initiation of the risk for blow-through of steam, cooling that is proportional to the risk is activated. It is possible in this simple manner to avoid the emission of gases from the chip bin when interruptions in the process occur, whereby the release of odours into the surroundings can be minimised.

Abstract: Disclosed is a tube-type solid polymer fuel cell comprising a fuel gas channel (2) extending in the axial direction of a rod-like collector (1) on the outer circumference of the collector and a membrane-electrode assembly (MEA) (6) arranged on the outer side of the rod-like collector (1) and the fuel gas channel (2), wherein a fuel gas flows in the fuel gas channel (2) and an oxidizing gas flows outside the membrane-electrode assembly (MEA) (6). A part or the whole of the fuel gas channel (2) is filled with a porous material having through holes extending along the axial direction of the fuel gas channel (2), and corrosion-resistant conductive particles are mixed in the porous material. In this tube-type solid polymer fuel cell, a catalyst ink does not permeate into and clog the gas channel during formation of the catalyst layer, so that the gas flowability is improved while reducing the cell resistance during operation of the fuel cell. Consequently, the power generation performance of the fuel cell is improved.

Title: Use of fluorescent nanoparticles to make on-line measurements of cross-web and machine-direction component and property variations in paper and continuous web products
Inventor: TIXIER SEBASTIAN
IPC: D21G9/00
Filed: 2009-02-17
Abstract: Fluorescent nanoparticles such as quantum dots are incorporated into paper and other web products such as plastics to achieve cross-direction and machine direction on--line detection of selected components during manufacture. Fluorescent nanoparticles markers are added in known proportions into product formulations along with the selected components of interest. By detecting the fluorescence from the nanoparticles, the selected components can be traced at various stages of production. In addition, by using different fluorescent nanoparticles that emit radiation at different wavelengths, data from individual materials or layers in a composite structure can be ascertained simultaneously with a single sensor. The technique is particularly suited for monitoring expensive and difficult-to-measure components that may be present only in trace quantities. The technique can be implemented continuously during normal production, during start-up or re-formulation, such as a grade change in paper production, when considerable changes in the process parameters occur.

Inventor: BEECH ROBERT P
IPC: A61K31/711
Filed: 2007-07-26
Abstract: The present invention relates to methods and compositions for treating a subject comprising destroying diseased cells in the subject. The methods comprise obtaining a population of cells from a subject and determining the activity of at least one disease marker gene within the population of the obtained cells. A polynucleotide molecule that encodes a polypeptide that is lethal to the cells is then introduced into the cells, where the expression of the lethal polypeptide is controlled by the promoter of at least one of the disease marker genes previously identified. After introduction of the polynucleotide, the cells are treated with conditions to induce expression of the lethal polypeptide to destroy the cells that are expressing the disease marker gene(s). After destruction of the diseased cells, the remaining live cells, which did not express the lethal polypeptide to an extent necessary to kill the cells, are separated from the dead cells, and the live cells are restored to the subject.
