摘要： A hydrogen-absorbing alloy electrode is prepared by reducing an oxide or hydroxide residing on the surface of a hydrogen-absorbing alloy particle while the alloy particle is held in an atmosphere of a hydrogen gas maintained at a temperature where absorbing of a hydrogen gas does not substantially occur; cooling the atmosphere from a temperature where absorbing of the hydrogen gas does not substantially occur to a temperature where the equilibrium hydrogen pressure of the hyrogen-absorbing alloy is equal to the hydrogen pressure in the atmosphere of the hydrogen gas and thereafter vacuum-evacuating and removing the hydrogen gas so that the hydrogen-absorbing alloy particle is cooled to room temperature while the hydrogen gas is exhausted; and thereafter introducing argon, nitrogen or carbon dioxide gas into the atmosphere, thereby returning the atmosphere to normal atmospheric pressure; and immersing the hydrogen-absorbing alloy particle so prepared in a solution containing an oxidation inhibiting agent.

摘要： An arrangement for transporting metallic work pieces includes a heat-insulated transport chamber, means for loading and unloading the work pieces, and transporting gear. To enable the flexible and efficient transport of the work pieces among a number of treatment chambers in an arrangement of this type during a heat treatment process, the transport chamber is designed to be vacuum-tight, such that it can be evacuated of air to create a vacuum that will protect the work pieces from environmental influences. In addition, a system for heat treating metallic work pieces, comprising at least two treatment chambers in which the work pieces can be heat treated, is characterized in that an arrangement of this type can be coupled to the treatment chambervia a transfer canal that can be evacuated. Furthermore, in a method for transporting metallic work pieces during a heat treatment process, a vacuum-tight transport chamber is evacuated to create a vacuum that will protect the work pieces from environmental influences, for the purpose of transporting the work pieces within this vacuum from one treatment chamber to the next.

摘要： A nozzle for injecting a cooling gas in a vacuum heat treating furnace is described. The cooling gas injection nozzle according to the present invention has a forward portion with a first central opening formed therethrough. The cooling gas injection nozzle also has a rear portion with a second central opening formed therethrough. A flap is disposed in and pivotably supported in the first central opening. The flap operates to substantially prevent the escape of heat from the hot zone during a heating cycle, but permits the injection of the cooling gas into the furnace hot zone during a cooling cycle. The cooling gas injection nozzle is supported from the hot zone wall by any appropriate means. A vacuum heat treating furnace and a hot zone therefor incorporating the cooling gas injection nozzle are also described.
