(under subclass 615) Subject matter in which a component has 40 percent or more of barium, beryllium, calcium, magnesium, radium or strontium, or a combination of two or more of these metals.
(1) Note. The mere designation of a base component as an "alkaline earth metal" is sufficient for placement in this subclass.
(2) Note. The term "light metal" is interpreted to mean a magnesium-base alloy, an aluminum-base alloy, or an alloy comprising 40 percent or more of these two metals. In not further explained in the claims, a patent claiming a "light-metal" component is placed here and in the proper subclass included in 650+.
