5/490762

Inventors:

Paul E. Robertson - Houston TX

International Classification:

B23K 912

US Classification:

219125R

Abstract:

Automatic arc welding apparatus in accordance with the present invention comprises a welding carriage movably supported by a horizontal guide beam, which carriage supports a plurality of arc welding heads for forming welds on a generally horizontally disposed work piece, wherein the welds may be of compound curvature. The welding head mechanisms are supported by compound connection apparatus that defines three interrelated axes that are cooperatively related to enable an electrode support to which welding wire electrode is automatically fed to precisely follow a joint of compound configuration that is established between angularly related portions of the work piece. Additionally, the welding head mechanisms are movable both vertically and laterally to facilitate proper positioning thereof to the work piece being welded.

Abstract:

A protection system, method, and a security device can protect an Internet of things (IOT) system having connected hardware equipment, including at least an interface that can receive a control communication for controlling at least one connected device. They feature tasks/steps that intercept control communication between a controller and a connected device, determine whether the received control communication contains an undesirable control command, and either pass or block the received control communication to the connected device depending on whether the received control communication contains an undesirable control command. The security device can be disposed between a source of communication in an IOT network and the connected device for protection.
