The high-pressure metal halide discharge lamp has tungsten electrodes in a light-transmitting lamp vessel which is closed in a vacuumtight manner. The electrodes comprise an emitter which is distributed throughout their mass and is formed by a first oxide chosen from hafnium oxide and zirconium oxide and by a second oxide chosen from yttrium oxide, lanthanum oxide, cerium oxide and scandium oxide, and are substantially free from thorium oxide. The lamp retains its initial light output to a high degree throughout its life.

Method of manufacturing a dispenser cathode, in which method tungsten and a scandium-containing material are mechanically alloyed and the product thus formed is pressed into a cathode body. The cathode body is further provided with a barium-containing component. In the mechanical alloying process the tungsten is highly deformed and the scandium-containing material is mixed with the tungsten so as to be very finely distributed therein, so that an improved dispensation of scandium and hence an improved recovery after ion bombardment of the final cathode is attained.

Dispenser cathode and method of manufacturing a dispenser cathode

Method of manufacturing a dispenser cathode

A system for purifying a gas provided with an apparatus comprising a main container defining a substantially closed chamber, an intake fitting having an intake projecting from the chamber and having inside the chamber a filter element, an outlet fitting having an outlet projecting from the chamber offset from the intake and having inside the chamber a filter element offset from the filter element of the intake fitting, and means defining in the chamber an internally sealed well between the filters. A baffle is provided in the chamber between the filters so that gas passing between the filters is deflected by the baffle. A heater is provided in the well. An outer container surrounds the main container and defines a space therearound. This space is insulated, either by being filled with an insulating material or by being evacuated. An active material generally fills the chamber around the filters and well so that a gas passing through the chamber from the intake filter to the outlet filter contacts the active material. Optionally the device may also have partitions defining in the chamber a second internally sealed well or a thermocouple. This thermocouple permits one to monitor the temperature of the active material bed.

Gas purifier

The method for extracting hydrogen from a gas stream containing hydrogen with or without other gases by a sorption-desorption process using as the hydrogen sorber a pellet bed of a porous, metallurgically bonded, heat-ballasted hydridable mixture comprising a major proportion of a heat-ballast material and a minor proportion of a hydridable metallic material.

Methods of extracting hydrogen from a gas

A porous, metallurgically bonded, heat-ballasted hydridable mixture in pellet form wherein the solid ingredients comprise about 40 vol. % or less of a hydridable metal or alloy and about 60 vol. % or more of a ballast metal powder from the group consisting of nickel, copper, iron and aluminum.

Metal bound and ballasted hydridable pellets

A hydrogen sorbent composition is provided which is comprised of a hydridable material such as LaNi.sub.5 encradled throughout a porous, fiber-containing polymeric composition.

Hydrogen sorbent composition

A process is provided for forming a polymeric material which can be developed into a shaped polymeric structure comprising an active material encradled in a porous, fiber-containing polymeric composition. In the process, the active material is mixed with a tripartite system comprising a fibrillatable polymer, a support-contributing polymer and a pore-former. When such a system is mixed and developed with an active material, such as LaNi.sub.5, an active composition is produced which may be used, for example, as a hydrogen collecting or storing material.

Production of a polymeric active composition

A particulate catalyst composition is provided by processing components in standard polymer processing equipment to obtain catalyst particles encradled in a porous, fiber-containing polymeric material.

Particulate catalyst and preparation

A catalyst composition is provided as a thin flexible sheet in standard polymer processing equipment. The catalyst is comprised of catalyst particles encradled in a porous, fiber-containing polymeric material.
