Abstract

527,669. Altering physical structure. HEROLD, W. April 18, 1939, No. 11728. [Classes 83 (ii) and 83 (iv)] Making rods and bars.-In a method of producing high grade metal rods and bars, particularly for concrete reinforcement, the bars are twisted in the cold and simultaneously subjected to a tensile force which does not exceed the tensile yield point of the material. The tensile force may be constant or varied during the twisting. Specification 472,744 is referred to.
