Abstract: A device for gripping, lifting and releasing a member, such as a package or individual article, used in automatic handling apparatus where two gripping arms are pivotally mounted so that they can be pivoted into and out of gripping relation with a member. The device can grip the member and place it carefully on a surface where it is surrounded laterally by similar members. In the placing operation the member gripped and the laterally surrounding members are not deformed. The gripping arms are pivoted at one end and grip the member at the other. The pivoted ends of the gripping arms can be moved away from or toward one another while being pivoted for effecting gripping or releasing of the member.

Abstract: In a submerged arc multiple wire welding system, only one or two of the welding wires used are over or microalloyed wires. The other wires are commercially available unalloyed or low-alloyed solid wires. The process produces a weld metal which has unexpectedly high toughness values, and can be performed more economically. This multiple wire welding system is used in single or multiple-pass welding operations.
