Title: Fused beryllium-zirconium brazing process
Inventor: DOWNIE GERRY
IPC: B05D3/04
Filed: 1994-04-22
Granted: 2002-01-29
Abstract: A process for brazing zirconium alloy elements to zirconium alloy nuclear fuel sheaths is taught. The process includes applying an initial layer of beryllium to the surface of the element and heating the element to form a fused beryllium-zirconium alloy layer on the element. The element is then placed on a fuel sheath and once again heated to allow the alloy to flow to fill the space between the element and the sheath. The initial layer of beryllium can be applied to the element by use of a beryllium containing brazing paste or by vapour deposition. The present invention provides a good braze while avoiding the variable results obtained using previous brazing methods.

Abstract: A load-following vaporizer (10) converts an inlet liquid reactant stream to an outlet vapor reactant stream. The vaporizer (10) comprises a containment shell (11), a nozzle (l7) and a fin block (12). The fin block (12) has a base in thermal contact with a heat source, preferably a thermal fluid stream. The base has a plurality of evaporative heat transfer structures (44, 46) that are spaced from and generally radiate from the nozzle outlet. Each of the evaporative heat transfer structures has two principal surfaces oriented such that the extension of each of the surfaces intersects the nozzle (17) outlet. Upon contacting the evaporative heat transfers structures, the atomized liquid reactant dispersion is vaporized to produce a vaporized reactant stream (24). The vaporizer rapidly responds to changes in the inlet liquid (22) reactant flow rate to produce a corresponding change in the output vapor flow rate by minimizing the liquid inventory within the heated environment. The load-following vaporizer is compact, light-weight and compatible with other components of an integrated fuel processing system.

Abstract: Un élément de liaison (18), s'étendant à travers une cavité (16), dans un substrat à semiconducteurs (12), (par exemple en silicium polycristallin) comporte des couches successives - une couche de masquage (20), une couche conductrice électriquement (22), (par exemple en polysilicium) et une couche isolante (24) (par exemple SiO2). Un premier contact électrique (32), (par exemple de l'or revêtu de ruthénium) s'étend sur la couche isolante dans un sens perpendiculaire à celui de l'élément de liaison à travers la cavité. Une paire de bosses (34) (par exemple en or) est disposée sur la couche isolante chacune entre le contact et une des extrémités de la cavité. On réalise initialement sur le substrat l'élément de liaison (18) et, ensuite, le contact (32) et les bosses (34), puis on grave la cavité (16) par attaque chimique dans le substrat à travers des orifices de l'élément de liaison. Une paire de deuxièmes contacts électriques (44) (par exemple de l'or revêtu de ruthénium) se trouve sur la surface d'un substrat isolant (14) (par exemple en verre pyrex) contigu au substrat à semiconducteurs. Les deux substrats sont collés après nettoyage des contacts. On sépare normalement le premier contact (32) des deuxièmes contacts (44), étant donné que les bosses (34) viennent en contact avec la surface du substrat isolant. Quand on applique une tension entre une couche conductrice de la surface du substrat isolant et la couche en polysilicium, l'élément de liaison est défléchi (18), de telle manière que le premier contact (33), vient en contact avec le deuxième contact (44). Des fils électriques s'étendent sur la surface du substrat isolant depuis les deuxièmes contacts vers des pastilles de connexion situées en position contiguë à une deuxième cavité du substrat à semiconducteurs. On peut séparer les relais obtenus sur une tranche en découpant le semiconducteur et les substrats isolants au niveau de la position de la deuxième cavité dans chaque relais, de façon à découvrir les pastilles pour effectuer les branchements électriques.

Abstract: Novel maleimide copolymers have at least two monomeric units, a maleimide unit and a vinyl unit having a pendant group, the pendant group having two to twenty-one carbon atoms, at least one nitrogen atom and at least one oxygen atom. The copolymer has an average molecular weight between about 1,000 and about 6,000,000. Preferred maleimide copolymers include acrylamide/maleimide copolymers, N-vinyl amide/maleimide copolymers, vinyl lactam/maleimide copolymers, alkenyl cyclic imino ether/maleimide copolymers, and acryloylamide/maleimide copolymers. The substantially water soluble maleimide copolymers are useful for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents by reducing the rate of nucleation, growth, and/or agglomeration of gas hydrate crystals in a petroleum fluid stream, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.

Abstract: A fabric for use as a base fabric in an air bag comprises a fibrous substrate having adhered to it a covering layer made of a thermoplastic synthetic resin and of 10 µm or less in average thickness. The adhesion between the fibrous substrate and covering layer is effected by causing the thermoplastic synthetic resin material of the covering layer to fill intersteces between the fibers of the fibrous substrate. This may be achieved by applying to the fibrous substrate a solution or dispersion of the thermoplastic synthetic resin. An air bag may be constructed entirely from the fabric such that when it comprises sheet material additional to the base fabric, these may also be provided by the same fabric as that used for the base fabric.
