Abstract: The present invention relates to an inflatable pad with a built-in pump, mainly comprising an inflation unit and a air pump assembly inside the inflation unit. The inflation unit has an inflation chamber with laminated fringe while the air pump is composed of a protuberant pump chamber and an inflation/deflation channel.   Especially, on one side of the pump chamber there are two pieces of unidirectional membrane tubing, A and B, in a reverse loop. The membrane tubing B is provided as a channel between the pump chamber and the inflation chamber. The membrane tubing A is installed inside the pump chamber so that one end connects to the pump chamber and the other end at the chamber edge connects to a piece of round tubing.   The round tubing connects to the laminated edge of the inflation chamber and has an insertable hollow bolt so that an inflation access is formed. On the proper place of the round tubing surface, there is a vent bole. When the hollow bolt is removed from the round tubing, a deflation channel is formed. Thus, a complete air flow channel is constructed to provide convenience of use, adjustable inflation, and immediate action of inflation and deflation.

Title: Fluorescence polarization-based homogeneous assay for deoxynivalenol determination in grains
Inventor: NASIR MOHAMMAD SARWAR
IPC: G01N33/569
Filed: 2001-09-10
Abstract: a homogeneous assay for determining the deoxynivanlenol (DON) content in grains uses the technique of fluorescence polarization. A grain extract is prepared by shaking a crushed grain sample with water. A mixture is prepared by combining the grain extract with a tracer and with monoclonal antibodies specific to DON. The tracer is able to bind to the monoclonal antibodies to produce a detectable change in fluorescence polarization. The tracer is prepared by conjugating DON to a suitable fluorophore. The fluorescence polarization of the mixture is measured. The DON concentration of the mixture may be calculated using a standard curve obtained by measuring the fluorescence polarization of a series of DON solutions of known concentration.

Inventor: NGUYEN PHILIP D
IPC: E21B43/04
Filed: 2003-03-28
Abstract: Improved methods and apparatus for completing well s and gravel packing an interval of a wellbore are provided. The methods include the steps of placing a perforated shroud having an internal sand screen disposed therein in the zone, and injecting particulate material into the annuli between the sand screen and the perforated shroud and the perforated shroud and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. The perforated shroud has a flow-controlling means for restricting fluid movement between the casing/shroud and shroud/screen annuli during gravel packing. The flow-controlling means may be comprised of a material installed on a selected number of the shroud perforations which blocks or partially blocks fluid flow through the otherwise permeable wall of the perforated shroud during gravel packing. Preferably, the material is removable after the gravel has been placed, such as by melting or dissolving, to accommodate production flow during the production phase without restriction. Materials suitable for application in the improved methods include magnesium oxide/magnesium chloride/calcium carbonate mixtures, oil soluble resins, waxes, soluble polymers, etc. Other suitable materials employ other mechanisms such as temperature, oil solubility, internal breaker or flow shear stress to remove them.

Patent CA-2429064-A1 (CA)
Inventor: FERRARO EMILIO
IPC: H02J3/01
Filed: 2001-11-19
Abstract: Une large gamme de charges électriques, telles que par exemple des lampes à décharge gazeuse ou des charges électroniques, présente des concepts fonctionnels hors des normes communes (résistivité, induction, capacitance). Ces charges induisent, pour leurs propres caractéristiques fonctionnelles, des distorsions harmoniques sur le courant absorbé qui ne peuvent être réduites par les systèmes de compensation normaux (par exemple avanceurs de phase). Un problème de correction affecte les lignes d'alimentation et leurs générateurs respectifs réduisant ainsi leur efficacité, la capacitance de puissance qui peut être fournie, et le niveau qualitatif de distribution d'énergie. Le système permet d'évaluer et de compenser (pour la partie de l'énergie autorisée par la section de puissance) la distorsion harmonique sur le réseau, ce qui permet d'améliorer les différents paramètres qui caractérisent ledit système. En outre, du fait que le système peut fonctionner à la fois comme charge et comme générateur, il peut être structuré de façon à utiliser des sections de puissance déjà utilisées pour gérer d'autres applications, ce qui réduit grandement le prix de l'appareil/rapport de puissance corrigée.
