Experience has shown, said Dr. Moore, that while the five-day process is "excellent" for treating the syphilitic infection, it brings "an enormous increase in the danger to the patient."

Germany's contribution to powder metallurgy came about 1916 when the great Krupp Works learned from the electrical industry to press and sinter mixtures of tungsten carbide with cobalt into the hardest cutting compound known, began producing it commercially. These hard-cemented carbides have a hardness between diamond and sapphire. They are often shaped into cutting tools by another product of powder metallurgy: a solidified mixture of diamond dust and bronze powder. They work without softening at high, cherry-red heats while cutting ordinary armament steels two to ten times faster than cutting tools made of the toughest high...
