Machines for mechanical straightening of steel supports, including hydraulic girder straightener; special horizontal hydraulic press; machine, cam-operated, and belt-driven from motor, for cold-straightening composite steel-tube props and steel arches; use of rolled steel joists for roof supports underground has now assumed such importance that question of modification of present B.E.S.A. standard would seem worthy of consideration.
