Inventor: BOGATIN YAKOV
IPC: B22F1/145
Filed: 1990-06-13
Abstract: This invention relates to a process for producing a rare earth-containing material which is resistant to oxidation and non-pyrophoric comprising treating the rare earth containing material with a passivating gas at a temperature below the phase transformation temperature of the alloy. Rare earth-containing alloys suitable for use in producing magnets utilizing the powder metallurgy technique, such as Nd-Fe-B and Sm-Co alloys, can be used. The passivating gas can be nitrogen, carbon dioxide or a combination of nitrogen and carbon dioxide. If nitrogen is used as the passivating gas, the resultant rare earth material surface concentration of from 0.4 to about 26.8 atomic percent. If carbon dioxide is used as the passivating gas, the resultant rare earth containing material carbon surface concentration of from about 0.02 to about 15 atomic percent.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for separating and counting coins comprising a pair of rail spaced from each other to define a coin slot and a closed-loop chain for stably moving coins of different diameters on the pair of rails. The two rails are inclined with respect to a horizontal plane so that the coins are supported thereon in an inclined manner. The coin slot increases incrementally from an upstream of the coin slot to a downstream of the coin slot. Each coin, which has a diameter larger than a first width of the coin slot at the upstream and smaller than a second width of the coin slot at the downstream and moves along the coin slot, falls from the pair of rails. A counting device is suitably provided near the coin slot so that, upon falling of the coin. a count is registered.
