Patent EP-0727007-A1 (EP)
Inventor: LEGGETT HENRY H
IPC: E21B19/22
Filed: 1995-08-29
Abstract: L'invention concerne un mécanisme de poulie pour câble de forage à l'épreuve de la pression, constitué d'un corps de poulie (48) muni d'un carter (54) concourant à délimiter avec le corps susmentionné la chambre interne circulaire (104) de la poulie, laquelle est soumise à une pression de service telle que la pression d'un puits lors d'activités d'entretien de puits. Une poulie fendue (116), présentant une gorge externe (120) pour le câble de forage, se trouve dans la chambre interne et s'appuie, dans sa rotation autour de son axe, sur des roulements (114) situés dans sa périphérie interne. Lorsque le mécanisme de poulie fonctionne, la périphérie interne de la chambre interne de la poulie est alimentée en lubrifiant en un point (124) adjacent au système de roulement et à une pression supérieure à la pression du puits pour interdire la migration d'impuretés, induite par celle-ci, depuis la gorge susmentionnée jusqu'aux roulements. Des joints (130, 132) de chaque côté de la chambre interne de la poulie assurent l'étanchéité entre le corps et le carter de la poulie et font que l'action d'une force, induite par la pression du puits et s'appliquant au carter, se limite sensiblement à celle d'une contrainte périphérique. De la sorte, le mécanisme est à l'abri d'un chargement sur les parois latérales induit par une pression élevée.

Abstract: This invention relates to a radiant tube burner used for heating a heating furance, and aims at minimizing the occurrence of NOx during combustion and forming the radiant tube burner to a structure suitable therefor. This invention aims at simplifying the controlling of a fuel supply system and an air supply system, and preventing the necessity of a coking operation. This invention also aims at providing a combustion control method suitable for a radiant tube burner. To achieve these objects, the free ends of fuel nozzles in the present invention, for example, nozzles (11) serving also as pilot nozzles and air throats (13) are disposed in the end portions of a radiant tube (3), and combustion air ejection ports (33) of the air throats (13) are provided eccentrically so as to contact or get close to an inner circumferential wall surface of the radiant tube (3). A controller (307) for subjecting the burner to alternating combustion is also provided.

Abstract: Disclosed is a cathode (e.g., a Schottky emission cathode) having an electron emitter of a tungsten single-crystal with a sharp point, and a heater connected to the electron emitter to heat it. The work function of the crystal face of the point of the electron emitter is reduced by providing adsorbed thereon a nitride of Zr, Ti, Y, Nb, Sc, V or La, or an oxide of Y, Sc, V or La. The nitride or oxide can be formed as a reservoir on the heater (from where it thermally diffuses to the point), or chemically adsorbed on the point. For forming the nitride or oxide on the point, the metal forming the nitride or oxide can be provided on the point and reacted with nitrogen or oxygen thereat to form the nitride or oxide; to provide the metal on the point, the metal forming the nitride or oxide can either be evaporated onto the point, or can form a reservoir on the heater and thermally diffuse therefrom to the point. The effect of reducing the work function results in a cathode having a narrow FWHM (full width at half maximum) of emission electrons and a high current density. Moreover, the cathode of the present invention is easy to manufacture and handle.

Abstract: This invention relates to a process for the production of lower aliphatic esters by reacting a lower olefin with a saturated lower aliphatic mono-carboxylic acid in the vapour phase in the presence of a heteropolyacid catalyst characterised in that an amount of water in the range from 1-10 mole % based on the total of the olefin, aliphatic mono-carboxylic acid and water is added to the reaction mixture during the reaction. The presence of water enhances the yield of the desired ester. The reaction mixture may optionally contain a di-ether to minimise the by-products. 
     The process is particularly suitable for producing ethyl acetate from ethylene and acetic acid in the presence of water.
