Abstract: La présente invention concerne des procédés et un appareil permettant la mise en oeuvre de dispositifs d'analyses microfluides. Une membrane élastomère monolithique associée à une rampe de distribution pneumatique intégrée permet la mise en place et la mise en action de matrices denses de diverses structures de gestion des fluides, et notamment des structures permettant d'isoler, d'acheminer, de fusionner, de séparer et de stocker des volumes de fluide. Ces structures de gestion des fluides convient à la mise en oeuvre d'un système de détection et d'analyse d'agents pathogènes avec capture et analyse intégrées de l'immunoaffinité, telle qu'analyse par amplification par la polymérase (PCR) et analyse par électrophorèse capillaire (CE). Une solution d'analysat peut être introduite dans le dispositif et pompée via une série de matrices de capture par immunoaffinité dans des chambres micro-usinées où des anticorps sont ciblés vers les diverses classes d'organismes microbiologiques tels que les bactéries, les virus et les spores bactériennes. Les chambres d'immunoaffinité peuvent capturer, purifier, et concentrer la cible en vue d'opérations ultérieures d'analyse.

Title: Hand held milk foamer
Inventor: ARMSTRONG RICHARD JAMES
IPC: A23P30/40
Filed: 2005-11-30
Abstract: A hand held motor operated appliance for foaming milk in a serving container is described and employs an aerator characterized by a flat faced spinning disc held close to a fixed cylindrical shroud thus forming a thin annular air nozzle which is immersed in the milk. A detachable air pipe is adapted to continuously supply air to the submerged air nozzle during foaming of the milk. Combination anti-swirl vanes and standoffs are provided to prevent the formation of a vortex and to enable an operator to rest the appliance on the bottom of the container thus to maintain the spinning disc an optimal distance from the container bottom. The anti-swirl vanes by preventing the formation of vertical mixing currents thereby prevent over foaming of the milk. The standoffs, by holding the improved aerator near the bottom of the container in the unfoamed portion of the milk ensures all the milk in the container will be completely foamed with uniformly fine bubbles of air thus to greatly enhance the taste. Further, the disc, shroud and air pipe are readily detachable for thorough cleaning.

Title: Method of building persistent polyhierarchical classifications based on polyhierarchies of classification criteria
Inventor: BABIKOV PAVEL
IPC: G06F17/00
Filed: 2004-08-27
Abstract: A method for providing a polyhierarchical classification includes identifying properties of objects useful for distinguishing objects under classification. A plurality of criteria are identified for specializing the identified properties. A form is chosen for attributive expressions that describe classification categories. The attributive expressions are customizable and encode compositions of object properties in terms of attributes from the plurality of criteria. A domain of applicability is identified for each criterion that is representable by attributive expressions, and a dependence relationship between criteria is defined by the inclusion of attributes in the attributive expressions, where a selected criterion depends on another criterion if its domain of applicability includes at least one attribute by the other criterion. A generating polyhierarchy of criteria is automatically established by the dependence relationships between the criteria. The generating polyhierarchy of criteria implicitly defines an induced polyhierarchy of classification categories.

Inventor: RAMME BRUCE W
IPC: C04B38/10
Filed: 2006-02-21
Abstract: A process for sequestering carbon dioxide from the flue gas emitted from a combustion chamber is disclosed. In the process, a foam including a foaming agent and the flue gas is formed, and the foam is added to a mixture includi ng a cementitious material (e.g., fly ash) and water to form a foamed mixture. Thereafter, the foamed mixture is allowed to set, preferably to a controlled low- strength material having a compressive strength of 1200 psi or less. The carbon dioxide in the flue gas and waste heat reacts with hydration products in the controlled low-strength material to increase strength. In this process, the carbon dioxide is sequestered. The CLSM can be crushed or pelletized to form a lightweight aggregate with properties similar to the naturally occurring mineral, pumice.

Filed: 1998-07-14
Abstract: An equipment inspecting and evaluating system can be used to inspect and evaluate steam traps by detecting a level of vibrations of each trap and the surface temperature of the housing of that trap. The detected vibration level and temperature are used to determine whether or not steam is leaking through that trap and to what extent steam leakage is. An equipment management system is connected to the inspection and evaluation system by a data transmission cable and receives inspection data of the traps from the inspection and evaluation system. The management system analyzes the received inspection data for computing the number of defective traps, the ratio of defective traps to the entire traps, the loss caused by steam leakage, etc.
