Abstract
925,662. Concrete reinforcing rods. NOCKENSTAHL G.m.b.H. Aug. 5, 1959 [Aug. 6, 1958], No. 26776/59. Class 20 (4). [Also in Group XXII] A concrete reinforcing rod produced by hot rolling and hardened by cold stretching, has longitudinal beads 4 and ribs 2 inclined to the axis of the rod at an angle of 30 to 60 degrees, which ribs decrease gradually in section towards their ends where they run out completely just before reaching the beads. The rod may be given a slight twist during stretching.
