Abstract: Disclosed herein are embodiments of an Al—Ce—Ni alloy for use in additive manufacturing. The disclosed alloy embodiments provide fabricated objects, such as bulk components, comprising a heterogeneous microstructure and having good mechanical properties even when exposed to conditions used during the additive manufacturing process. Methods for making and using alloy embodiments also are disclosed herein.

Abstract: The invention provides a modular pipe handling system comprising a lift arm assembly including a base member and a lift arm mounted on the base member. The lift arm is pivotable between a horizontal and vertical position. The lift arm further comprises at least one clamping system for clamping a length of pipe to the lift arm, to allow movement of the pipe between the horizontal and vertical positions. The base member includes a leveling system associated therewith for independent leveling of the base member and corresponding lift arm relative to a drilling rig with which the pipe handling system is used. The base member may also include a positioning system for positioning of the base member a predetermined distance from the drilling axis of a predetermined drilling rig, wherein the positioning system is adaptable to vary the distance from the drilling axis.

Abstract: An earthquake resistant equipment rack that includes multiple methods for reinforcing the equipment rack to resist seismic forces. The side rails can include two inwardly projecting V portions extending the length of the rails to diffuse seismic forces by deflecting seismic forces vertically. The base and top are preferably formed from multiple components formed from sheet metal and having both over-lapping multiple thickness of sheet metal and multiple box structures. A cover is non-removably attached to the base. In one embodiment, the cover has a dog house shape with inclined roof like surfaces.
