Abstract

1453688 Mine support sections BERGBAUSTAHL GmbH & CO 25 Feb 1974 [3 March 1973] 8365/74 Heading E1E In a mine arch support iron of channel section having a base portion and a flange 12 separated by a web portion, the latter portion is subdivided into transition three zones 1, 2, 3 each having inner and outer boundary lines defined by parabolas, the parabolas of one zone being different from and merging into the parabolas of the adjacent zone or zones. For full mathematical desiderata, nesting characteristics and advantages over the prior the Specification should be referred to.
