Abstract: A method for producing a contact material on the basis of silver-tin oxide or silver-zinc oxide is disclosed. Tin oxide particles and/or zinc oxide particles are mixed with a powder of a metal different from silver. The mixture is heated beyond the melting point of the metal powder such that the tin oxide particles and/or zinc oxide particles are wetted with liquid metal. The mixture is exposed to an atmosphere containing oxygen and the metal is thereby oxidized. Thereafter, the mixture product formed by the oxidation step is embedded as a powder into a silver matrix. The product further relates to a corresponding contact material.

Abstract: A method for making Mg brass EDM wire has the steps of melting a charge of Mg brass to form a melt of Mg brass; transferring the melt to a holding furnace; casting a rod from the melt; and drawing the rod down to a size suitable for EDM machining. Mg deposits may form in the holding furnace. These can be removed by flushing the holding furnace with molten brass.

Abstract: The present invention relates to kits and methods for calibrating a pump through performance of a thermal knockdown process including demagnetization of an impeller of the pump where the impeller is separate from the pump. By heat treating the impeller, a property of magnetic interaction of the pump is reduced in a repeatable manner. A kit includes a pump with impeller, a controller and an oven. The method generally involves an iterative process of testing the pump for a property related to magnetic interaction of the elements of the pump, removing the impeller from the pump, heating the impeller under controlled conditions, then placing the impeller back into the pump to repeat the test performed initially.

Abstract: In a method of manufacturing a permanent magnet having a curved surface, a permeating material including metal particles and a flux is applied to the curved surface of a magnet. The magnet to which the permeating material is applied is then positioned within a furnace and the furnace is placed in a vacuum or filled with inert gas to volatilize a solvent and the like of the flux contained in the permeating material. The furnace is set to be a temperature within a range of 300 through 500 degrees C. to heat the permeating material. This enables the flux to be carbonized to form reticulated carbon. The furnace is then set to be a temperature within a range of 500 through 800 degrees C. to melt the metal particles in the permeating material, thereby permeating the melted metal particles into the magnet through the reticulated carbon uniformly.

Abstract: An iron alloy powder consists of, when the entirety thereof is assumed to be 100 mass %, Cr: 2.5 mass % to 3.5 mass %, Mo: 0.4 mass % to 0.6 mass %, and Fe and inevitable impurities as the balance, a mixed powder consisting of 15 mass % to 40 mass % of the iron alloy powder, 1.2 mass % to 1.8 mass % of a copper powder, 0.5 mass % to 1.0 mass % of a graphite powder, and a pure iron powder as the balance when the entire mixed powder is assumed to be 100 mass % is compacted into a compact, and the compact is sintered while transforming a structure derived from the pure iron powder into a structure in which a ferritic structure and a pearlitic structure are mixed and transforming a structure derived from the iron alloy powder into a martensitic structure.

Abstract: A method includes the sequential steps of compacting a powder metal in a tool and die set using a compaction press to form a powder metal compact, ejecting the powder metal compact from the tool and die set, positioning the powder metal compact relative to another part, and cooling the powder metal compact. When the powder metal is compacted, a temperature of the powder metal used to form the powder metal compact increases relative to ambient temperature due to deformation of the powder metal during compacting. After ejection and while the powder metal compact is still above ambient temperature, the compact is positioned relative to the other part. Then, upon the cooling of the powder metal compact, the powder metal compact dimensionally shrinks to form an interference fit between the powder metal compact and the other part thereby forming the composite component, which may be subsequently sintered.

Abstract: A process for digestion of fine iridium includes (a) alkaline oxidative digestion of 1 part by weight fine iridium and 3 to 20 parts by weight of a combination comprising 40 to 70 parts by weight sodium hydroxide, 15 to 30 parts by weight sodium nitrate, and 10 to 40 parts by weight sodium peroxide in the melt, whereby the sum of the weight fractions equals 100 parts by weight; (b) cooling the digestion material formed in step (a) to 20 to 70° C.; (c) dissolving the acid-soluble fractions of the cooled digestion material in water/halogen hydracid until an acidic aqueous solution with a pH value of ?1 to +1 is obtained; and (d) boiling the acidic aqueous solution obtained in step (c) until the formation of nitrous gases is completed. Insoluble ingredients can be separated from the acidic aqueous solution before or after step (d), if needed.

Abstract: A tie-down anchor is provided for strapping cargo to a cargo bed. The tie-down anchor includes a receptacle member, which in turn includes a base and a mounting flange secured to the base. The mounting flange is mounted to the cargo bed in alignment with a mounting hole in the bed. A strap-receiving member is disposed in the receptacle member supported on the base for floating rotary and pivotal movement. The strap-receiving member includes a base leg having a length greater than the diameter of the mounting hole and an extension fixed to the base leg to create an opening for receiving the strap. The extension is narrower than the mounting hole so that the extension may pass through the mounting hole and extend above the bed.
