Abstract: A method of forming a hydrogen transport membrane to separate hydrogen from a hydrogen containing feed in which a porous ceramic support is formed to support a dense layer of palladium or an alloy of palladium serving as a hydrogen transport material. Isolated deposits of palladium, a palladium alloy or a component of such alloy are produced on a surface of the porous ceramic support that bridge pores within the porous ceramic support without penetrating the pores and without bridging regions of the surface defined between the pores. The isolated deposits of the metal are produced by an electroless plating process that involves contacting the porous ceramic support with a precipitating agent so that the precipitating agent fills the pores but does not seep out of the pores onto the regions of the surfaces defined between the pores. The surface is then contacted with a salt solution containing a salt of the metal so that said metal precipitates and produces the isolated deposits of the metal. Thereafter, the dense layer is formed on the surface having the isolated deposits.

Abstract: A method of separating oxygen from an oxygen containing feed and reacting the oxygen with a reactive substance and an oxygen ion transport membrane element utilized for such purposes. The oxygen ion transport membrane element has a self-supporting dense layer and a surface porous feature in contact with and supported by the dense layer. The porous surface feature may be a layer, a layer having discontinuities or a series of repeating geometrical forms. The dense layer and the porous surface feature are capable of conducting oxygen ions and electrons. The porous surface feature at least in part forms the anode side of the oxygen ion transport membrane element at which the reactive substance reacts with the separated oxygen and has a thickness less than that of the dense layer and a greater surface area than that of a surface of the dense layer adjoining the porous layer. Pores within the porous surface feature have a pore aspect ratio of pore size to pore length of between about 0.1 and about 5.

Abstract: The present invention provides an ion conducting ceramic membrane selectively permeable to a gas, for instance oxygen and a method of treating such a membrane to improve permeation through the membrane. The membrane is formed by a mass of a substance through which ions of the gas migrate. The mass has two opposed surfaces where dissociation and ionization of the gas occurs and gas ions release electrons and recombine to form molecules of the gas, respectively. At least one of said two opposed surfaces is treated by a removal of surface material to produce surface irregularities of increased area and therefore an increase in total surface area of a treated surface to in turn increase permeation of the gas. Preferably, both surfaces of the membrane are treated by chemical etching techniques, although sand blasting and ion etching are other possible surface treatments in accordance with the present invention.

Abstract: A joint assembly for joining a ceramic membrane of tubular form to a tube sheet used in supporting the ceramic membrane within a reactor. The ceramic membrane is received within a fixture connected to the tube sheet and a follower, extending into the fixture, exerts a force on a high temperature sealing element located between the fixture and the ceramic membrane to effect a seal and to hold the ceramic membrane in place. The force can be exerted directly on the sealing element or on the ceramic membrane itself.

Abstract: A process for coloring a metal surface and colored metal products thus produced. The process involves forming a layer of a metal oxide on a surface of the metal to be colored and then bringing about permanent plastic deformation of the surface. If the oxide layer is of a suitable thickness (e.g. 500.ANG.-1 .mu.m) and the deformation is sufficiently high (preferably producing a reduction in thickness of the metal article by 30% or more), the resulting metal article exhibits an attractive color (usually a dichroic pastel color). The article can then be fabricated into finished articles, e.g. beverage cans, in the usual way.

Abstract: A device for efficient transmission of electromagnetic waves comprising two layers of dielectric separated by a gap or space. The layers may be uniform or laminar, orthogonal or non-orthogonal to the direction of wave propagation, and made of Teflon, quartz, polypropylene, and the like. The preferred distance between layers is an odd multiple of quarter wavelength in the environment between the layers. The preferred thickness of the layers is an odd multiple of half of the effective wavelength for the layer. The device allows over 95% efficiency for transmission into a pressurized vessel for evaporation under high pressure and temperature and does not require a cooling system. The separating space may be connected with a pressure-sensing subsystem to monitor the device's integrity and shut down the system in the event of a breach. A sleeve connecting the device to the vessel may be coated with conductive material for improved efficiency.
