Abstract:
On ajoute un reactif aux effluents sortant d'une colonne (10) de chromatographie en phase liquide afin d'accroitre la sensibilite de detection, par un detecteur (10) de bande simple, ou pour ameliorer la sensibilite en ce qui concerne les bandes interferentes qui se superposent aux bandes que l'on cherche a analyser, en utilisant une ou plusieurs fibres creuses (36) immergees dans un reactif mobile (32) qui s'infiltre a travers les parois des fibres et qui par suite, diffuse dans l'effluent de la colonne.
Abstract:
The invention relates to the field of fuel tell technology, more specifically to a device and a method for supplying fuel to the anode of a direct alcohol fuel cell. Said device comprises a fuel accumulator in which the fuel is stored, and a flow- through device provided with a wall at least partially consisting of a membrane that is permeable to the fuel. Said flow-through device is used to guide a mixture of a carrier constituent and the fuel through the fuel accumulator, and the concentration of fuel in the mixture is increased by the diffusion of fuel through the permeable membrane.

Abstract:
PROBLEM TO BE SOLVED: To provide a gas nitriding furnace capable of efficiently nitriding a material which is hard to nitride or a work of a complicated shape to be nitrided, and forming an excellent nitride layer at a lower temperature in a shorter time than a known gas nitriding method. SOLUTION: In a step of maintaining a work W to be nitrided in a nitriding gas atmosphere in a closed furnace 1 and nitriding the work, nitriding is promoted by giving oscillation energy to one or both of the nitriding gas and the work W. The gas nitriding furnace comprises a closed nitriding furnace 1 to accommodate the work W, a nitriding gas feeding means 30 to feed nitriding gas into the nitriding furnace 1, and a means 2 to oscillate the atmospheric gas in the nitriding furnace 1. Nitriding is promoted by oscillating the atmospheric gas. COPYRIGHT: (C)2004,JPO
Abstract:
PURPOSE: To adjust particle diameter of an oil-soluble component and enable a reaction to proceed efficiently, by passing the oil-soluble component through minute holes provided in a hydrophilic substrate, when dispersing the oil-soluble component into a water-soluble component. CONSTITUTION: When dispersing an oil-soluble component (e.g., oleic acid) into a water-soluble component or an aqueous solution (e.g., glycerol) to induce a reaction in a heterogeneous system, the oil-soluble component is dispersed by passing it through minute holes (e.g., minute holes of about 0.3mm in diameter) provided in a hydrophilic substrate (e.g., a gypsum board). Accordingly, the particle size of the oil-soluble component can be adjusted, and the reaction can be made to proceed efficiently. COPYRIGHT: (C)1984,JPO&Japio
Abstract:
A method of converting C2 and/or higher alkanes to olefins by contacting a feedstock containing C2 and/or higher alkanes with a first surface of a metal composite membrane of a sintered homogenous mixture of an Al oxide or stabilized or partially stabilized Zr oxide ceramic powder and a metal powder of one or more of Pd, Nb, V, Zr, Ta and/or alloys or mixtures thereof. The alkanes dehydrogenate to olefins by contact with the first surface with substantially only atomic hydrogen from the dehydrogenation of the alkanes passing through the metal composite membrane. Apparatus for effecting the conversion and separation is also disclosed.
Abstract:
Apparatus and methods are disclosed for uniformly mixing fluid phases entrained in a porous material. A mixer may have a vessel and at least one porous material held by the vessel. At least one actuator may be acoustically coupled with at least one wall of the vessel for generating a wave. The wave effects mixing of at least two fluids in the porous material. The actuator may be a linear motor actuated with a control signal of predetermined frequency. The actuator may have a number of actuator pairs each including respective first and second actuators at respective first and second sides of the vessel. The actuators may be hinged for reciprocal movement. The actuators may be actuated to form a compression expansion wave to effect fluid motion in the porous material.
Abstract:
A container (1) for releasing a chemical additive (7) in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing (3) having a hollow interior and an additive composition (7) comprising at least one fluid material-soluble additive. The additive (7) is held within the container (1) by a least one fluid material-permeable element (11) provided at or near an opening (13) in the casing (1) and is effective to provide for release of additive(s) (7) into the fluid material.
