Abstract: Descaling of metal wire by bending is followed by projection of the scale from the wire. The scale, projected by nozzles in a descaling device, is a mixture of new scale coming directly from the wire undergoing the bendings and scale recycled several times by a recycle feedback path. This application is applicable to the treatment of steel wire known as "rod" coming from hot rolling.
Abstract: A method of producing a tubular lattice reinforced concrete pipe having a socket at one end including first providing a flat rectangular lattice of longitudinal and transverse members connected at their crossing points, and then forming the flat lattice into a tube; the transverse members are highly ductile and stretchable adjacent one end and this end is expanded to form the socket portion of the reinforcement.
