Method of applying a thermal barrier coating to a metallic article and a thermal barrier coated metallic article

A thermal barrier coated metallic article includes a platinum-group metal enriched outer layer on the article. The surface of the outer layer has a microstructure including a plurality of projections extending away from the metallic article. A thin adherent layer of oxide is formed on the outer layer of the metallic article. A ceramic coating is provided on the oxide layer on the surface on and around the projections. The ceramic coating includes a plurality of columnar ceramic grains which extend through the full thickness of the ceramic coating. The grains are arranged in clusters separated by gaps. The grains deposited around the projections are generally blocked. The projections reduce the stress in the ceramic coating near the interface with the adherent layer of oxide and also reduce the stress in the adherent layer of oxide and hence increase the working life of the thermal barrier coating system.

Heat storage materials

ABSTRACT Heat Storage Materials The material comprises at least one hydrated compound which undergoes reversible transformation to a less hydrated form and a fusion temperature-depressing salt, both dispersed and suspended throughout a water-swollen cross-linked polymer hydrogel (the hydrogel being as in European Patents 99 and 11411). The improvement is that the fusion temperature-depressing salt is present in 50 to 75% of the eutectic amount; this substantially reduces thermal hysteresis. In a modification of the invention, water is present in excess of the amount required to fully hydrate the compound, in which case the amount of fusion temperature-depressing salt may be 50 to 90% by weight of the eutectic amount.

A method of automatically generating lighting data for a three-dimensional computer generated entity is described. A mesh representation of at least a part of the entity is received and simplified by removing vertices from the mesh. For each vertex in the simplified mesh, a plurality of rays are propagated from the vertex and a cone-shaped region is then defined for the vertex using those of the plurality of rays that do not intersect with the simplified mesh, wherein the cone-shaped region is defined in terms of a vector and an angular parameter. An angular parameter and a vector for each vertex in the received mesh is then calculated by interpolating the angular parameters and vectors for each vertex in the simplified mesh and lighting data is output, the lighting data comprising the angular parameter and vector for each vertex in the received mesh.

Disclosed is a hair oil applicator comprising: (a) a container (1) comprising a base (2), upwardly extending walls (3) therefrom, threaded portion (4) at the upper end of the container and a top surface comprising a flat resilient member (5); (b) a closure cum dispenser (6) comprising a cylindrical cap (7), said cap comprising counter threads (8) on the inner side thereof capable of screw engagement with the threaded portion (4) of the container; (c) said cylindrical cap comprising an elongated horizontally placed distributor tube (9) on the top surface thereof; and said distributor tube comprising plurality of upwardly extending nozzles (10) configured to dispense the oil from the container; characterized in that the resilient member comprises an upwardly extending breakable tab (11) which when broken ensures that the distributor tube is in fluid communication with the oil in the container; and said cylindrical cap comprising an inner cylindrical stopper (12) and an outer cylindrical stopper (13) on the inner side thereof; said inner cylindrical stopper (12) capable of providing leakproof sealing for the oil when the closure-cum-dispenser (6) is screwed on tightly to the container (1); and said outer cylindrical stopper (13) capable of sitting flush against the perimeter of the top surface; thereby ensuring that the hair oil applicator is leak-proof around the threaded joints; and providing uniform dispensing of the oil through the nozzles (10).

Método y sistema para formar y dispensar un gas comprimido

Un método y sistema para formar un gas comprimido y dispensarlo a un receptor de gas comprimido. El gas comprimido se forma a partir de un fluido de proceso proporcionado a una temperatura criogénica. La formación incluye presurizar el fluido del proceso, alimentar el fluido de proceso presurizado a una temperatura aún criogénica a un intercambiador de calor y calentarlo en intercambio de calor indirecto con un termofluido que se proporciona en un depósito a una temperatura de termofluido por encima de la temperatura criogénica del fluido de proceso presurizado. Una vez calentado a una temperatura adecuada, el gas comprimido puede dispensarse al receptor de gas comprimido o almacenarse en uno o más recipientes de almacenamiento de gas comprimido para su uso posterior.

Aparato y método para el enfriamiento criogénico de una bomba

Un aparato y un proceso para enfriar una bomba para hidrógeno líquido u otro fluido criogénico pueden estar configurados para permitir un arranque rápido que además ayuda a minimizar las pérdidas de hidrógeno. Algunas realizaciones pueden utilizar un circuito de escape configurado y dispuesto para apoyar la operación de enfriamiento criogénico para la bomba que puede minimizar las pérdidas de hidrógeno a la vez que permite tiempos de arranque de la bomba sustancialmente mejorados. Algunas realizaciones pueden utilizar al menos un sensor de temperatura para monitorear la temperatura y una válvula de control ajustable que puede facilitar el flujo del fluido utilizado para llevar a cabo el enfriamiento de la bomba.
