Techniques, systems, and devices are described for a weld head that includes an adjustable clamping mechanism with a quick release insert. In one aspect, a weld head having an adjustable clamping mechanism for clamping a welding work piece includes a weld head containment structure having an opening that receives a welding work piece, a clamping member located inside the opening of the weld head containment structure and including a pivot joint for clamping the welding work piece to the weld head, a handle member connected to the clamping member at the pivot joint to rotate the clamping member when the handle member is moved, and an actuator coupled to the clamping member to enable the clamping member to pivot on the pivot joint to different clamping positions for clamping welding work pieces of different sizes.

A mounting mechanism for connecting a tractor unit to a guide track, the mounting mechanism includes a fixed block having a first set of rolling devices and a movable plate having a second set of rolling devices. The distance between the first and second sets of rolling devices is adjustable by moving the movable plate to engage or disengage the tractor unit to the guide track. A clamping assembly is provided with a shaft, cam spring, and cam handle for adjusting the distance between the first and second rolling devices. When the cam handle is in an open position, the distance between the rolling devices is greater than the width of the guide track and when the cam handle is in a closed position the distance between the rolling devices is approximately equal to the width of the guide track.

An electromagnetic shield has a first patterned or apertured layer having non-conductive materials and conductive material and a second patterned or apertured layer having non-conductive materials and conductive material. The conductive material may be a metal, a carbon composite, or a polymer composite. The non-conductive materials in the first patterned or apertured layer may be randomly located or located in a predetermined segmented pattern such that the non-conductive materials in the first patterned or apertured layer are located in a predetermined segmented pattern with respect to locations of the non-conductive materials in the second patterned or apertured layer.

A child safety barrier system includes a plurality of elongated panel sections having a predetermined height and width. At least one support joint is connected between two of the plurality of panel sections to support the plurality of panels in a freestanding vertical orientation to form a panel assembly. A pair of telescoping anchors are positioned along each end of the panel assembly. Each of the telescoping anchors including a header assembly along the top end having an omnidirectional joint for positioning a malleable header block against the ceiling of a building in a plurality of different orientations.
