Title: Device for measuring the quality and/or degradation of a fluid, particularly a food oil
Inventor: GIJS MARTIN
IPC: A47J37/12
Filed: 2003-12-30
Abstract: The instrument comprises a sensor (2) with a pair of spaced electrodes (4, 6), designed to be immersed in the fluid to form a capacitive measuring element and furnish a signal representative of the fluid's dielectric constant, the signal being processed to give an indication of the fluid's quality or degree of degradation. The electrodes extend in the same plane, with the fluid bathing both their faces on either side of the plane, and the signal from them is compared with a standard from electrodes (4ref, 6ref) of a reference capacitive component. The electrodes in both pairs are made from food grade steel, are comb-shaped, with interlocking parallel teeth, and are surrounded by a metal frame that acts as a screen against electromagnetic disturbance.

Title: Methods for fluid separations, and devices capable of separating fluids
Inventor: TEGROTENHUIS WARD E
IPC: F28D9/00
Filed: 2004-01-26
Abstract: A laminated, multiphase condensor having wicking structures and gas flow channels is described. During operation, a fluid mixture passes in through fluid inlet (2) into header (4) where it is distributed into gas flow channels (6 and 6'). Coolant passes through elongated coolant slots (8) in cooling channel layer (10). The material surrounding the coolant slots (8) are the cooling channel walls. As the fluid mixture passes through the gas flow channels (6 and 6'), heat from the fluid is removed primary heat exchange surface (13) (this surface also is an exterior surface of a cooling channel wall) and a liquid condenses from the fluid mixtu~re, flows into wick (11), through optional pore throat (12) and into liquid flow channel (14). The figure is an exploded view and shows a separation between the wick and the pore throat; however, in typical operation the optional pore throat should contact the wick. The device can work under the influence of gravity, but, more typically, sucti is applied to pull liquid out through liquid outlet (16) . In a device with multiple liquid flow channels, an optional footer (not shown) may carry flow from multiple liquid flow channels. Gas from the gas flow channels (6 and 6') may pass through an optional gas footer and out through gas outlet (20).

Filed: 2004-09-03
Abstract: La présente invention a trait à un procédé par lequel des images peuvent être calées à l'aide d'information temporelle (basée sur le temps) et spatiale. Dans le développement d'un film, étant donné que le film est une séquence de trames, l'utilisation d'information à partir de trames voisines peut permettre une expérience visuelle plus uniforme dans le temps. En outre, il peut être avantageux de profiter du fait que des trames consécutives sont souvent décalées lors du procédé de prises de vues. Des mesures de distorsion peuvent être utilisées qui ne tiennent pas compte de transformations candidates qui sont considérées comme étant trop éloignées d'une ou de plusieurs transformations préférées, telles que, par exemple, une transformation optimale à partir d'une autre trame ou d'un autre bloc ou une transformation actuellement optimale à partir de la même trame/du même bloc. Des images composites en couleurs peuvent être traitées pour assurer le calage de composantes sous-jacentes.

Title: Removal of carbon, nitrogen and phosphorus from waste water using fluidized beds
Inventor: CUI YUBO
IPC: B01D24/36
Filed: 2005-02-22
Abstract: Biological nutrient removal (BNR) in municipal wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations.  Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a liquid-solid circulating fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements. The BNR-LSCFB has two fluidized beds, running as anoxic/anaerobic and aerobic processes to accomplish simultaneous nitrification and denitrification and to remove carbonaceous substrates, nutrients and phosphorus, with continuous liquid and solids recirculation through the anoxic/anaerobic bed and the aerobic bed. The new BNR-LSCFB system is not only an excellent alternative for conventional activated sludge type BNR technologies but is also capable of processing much higher loadings and suitable for industrial applications.
