摘要:
The invention relates to a process for extrusion casting or conformation of a niobium oxide, in which the extruded profile is obtained by means of drying and calcination, in appropriate conditions, of a green extruded profile, which is obtained by extrusion casting of a niobium oxide viscous gel. The invention also relates to a process for preparation of a hydrolyzed and amorphous niobium oxide, in which the hydrolyzed and amorphous niobium oxide is synthesized from organic or inorganic niobium precursors. At last, the invention relates to uses of a niobium oxide in the extruded form.

L'invention concerne la régulation du débit de poudre dans un dispositif avec injecteur (2) aspirant la poudre (3) d'un récipient (4) par effet Venturi, l'injecteur (2) recevant ô son entrée un débit d'air d'injection (Dai) et, vers sa sortie, un débit d'air de dilution (Dad). Deux électrovannes proportionnelles (12, 13) sont placées respectivement sur l'arrivée (7) d'air d'injection et sur l'arrivée (8) d'air de dilution. Ces électrovannes (12, 13) sont commandées par un module de réglage (11) qui reçoit une consigne de débit de poudre (Dp) et qui détermine les débits d'air d'injection (Dai) et d'air de dilution (Dad) en tenant compte de coefficients mémorisés (A, B) et d'un débit d'air total minimum (Dam) ô respecter, sur la base de la formule : Dp = A.Dai - B.Dad. L'invention s'applique ô l'alimentation d'un appareil (10) de projection de peinture ou autre produit de revêtement en poudre.
摘要:
The present invention relates to a preparation method of carbides and nitrides of transition elements in extruded shape and from their oxides, with controlled porous volume and distribution. The meso and macroporous are generated by polymeric organic molecules such as microcrystalline cellulose, which after being burned form a more opened porous structure. The molding process involves the obtention of intermediate compounds that are susceptible to peptization and later extrusion. The preparation of these compounds, with porous diameter greater than 50 angstroms, implies in a range of catalytic reactions applications since more opened porous structures allow the catalytic process of larger molecules. Besides, in this way, there are less problems related to heat and mass diffusion processes. Problems which appear when dealing with very active catalysts and/or very exothermic reactions.
摘要:
La machine (4) est prévue pour dépoussiérer les carrosseries, avant l'application de couches de peinture sur celles-ci. Elle est conçue sur le principe de rouleaux de plumes montés tournants autour de leur axe central et entraînés en rotation, de manière à venir en contact avec des carrosseries entraînées en avant sur un convoyeur. Au moins deux rouleaux de plumes (26, 27) sont disposés dans le prolongement l'un de l'autre, et sont entraînés en synchronisme, l'angle formé par les axes respectifs (28, 29) des rouleaux consécutifs (26, 27) étant ajustable, par changement de l'inclinaison de l'un au moins de ces axes (28, 29). La machine s'adapte ainsi à des profils variables de carrosseries. Cette conception s'applique aux machines de toit et aux machines latérales de dépoussiérage.

摘要:
The present invention relates to compositions which are able to stimulate an immune response in a host inoculated with an antigen of interest or the gene vector that codifies it. This composition includes microspheres based on copolymers derived from lactic acid glycolic acid encapsulating antigens, gene vectors and/or adjuvants with immunostimulatory properties obtained from mycobacterial fractions. The materialization of the present invention is the use of trehalose dimycolate associated to a heat shock protein or to the plasmid containing the gene that codifies it, encapsulated in microspheres with size smaller than 10 μm, capable of inducing specific antobodies and cellular immune responses, as well as the secretion of cytokines implicated in the protection against infectious diseases and cancer, following administration of a single dose or several doses.

At least one of said trolleys (16) comprises a second connector (46, 48) which communicates with the first connector (46, 48).
摘要:
A presente invenção refere-se a um electrolisador alcalino, caracterizado por a electrólise ser efectuada sem separação dos gases Hidrogénio e Oxigénio, obtidos da dissociação da água, através de eléctrodos constituídos por grafite (2), que são isolados por placas separadoras (1), e fixados num reservatório (5), contendo água desionizada, devidamente vedado, ao qual é adicionado um electrólito, de hidróxido de sódio em baixa concentração, constituindo os eléctrodos terminais o polo positivo (4) e negativo (3). As placas de grafite (2) têm dois orifícios cada, criando dois canais de circulação do electrólito, o canal inferior (6) está ligado à entrada do electrólito, enquanto o canal superior (7) corresponde ao canal de saída do electrólito, arrastando os gases obtidos no processo de electrólise e oxidação. A presente invenção refere-se igualmente ao processo de electrólise, efectuado no electrolisador construído de acordo com a reivindicação N° 1, alimentado por uma fonte de energia eléctrica, obtendo-se uma mistura de gases contendo Hidrogénio e Oxigénio, que são canalizados para um reactor com a matéria carbonada, produzindo gás de síntese.
