Abstract: A drill bit for directional drilling includes a main body and a wear component. The main body is unitary and formed of a first material. The main body includes opposed outer surfaces and a periphery extending between the opposed surfaces. The wear component is unitary and is formed of a second material that is harder than the first material. The wear component comprises a retention portion and a wear portion. The retention portion is positioned within the first material of the main body. The retention portion includes opposed retention surfaces that, moving in a direction inward from the periphery of the main body, taper apart from each other toward the opposed outer surfaces of the main body. The wear portion extends outward from the retention portion relative to the periphery of the main body. The wear portion is substantially planar and is configured to form an outer wear edge.

Abstract: An improved shot blasting blade is disclosed with an attachment portion designed to slide into a radial slot in a shot blasting wheel. The blade has rails that contactingly ride on a top surface of the wheel just outside the slot, and two sets of opposed runners that extend into the slot and contact the top inner surface of the slot.

Abstract: Grain oriented electrical steel is made in a manner that the grains are selectively grown to obtain a crystal structure known as cube-on-edge and the grains are largely aligned in the rolling direction. Selection of chemistry and process route along with thin slab continuous casting enables the production of Grain oriented electrical steel such that less energy is consumed in the process, certain process steps can be combined, yield is better and the product can be manufactured within a wider process control tolerance.

Abstract: A spill pallet for supporting and providing secondary containment for at least one intermediate bulk container. The spill pallet consists of a base and side walls that form an open-top box structure. From the base of each of the four corners of the structure extend four pillars with flat upper surfaces. These pillars support a platform that covers a substantial portion of the structure. The platform contains a center support post that extends to the base of the structure. The container and platform have been adapted so that they can be nested with other containers and platforms for shipping.

Abstract: A mobile machine for lifting massive objects which includes a primary hydraulic cylinder whose piston chamber is hydraulically connected on a high pressure end thereof to a high pressure end of one or more secondary hydraulic lifting cylinders for operation of the lifting cylinder(s) in unison to lift the object. The total maximum effective volume of the piston chamber(s) of the secondary cylinder(s) is at least equal to the maximum effective volume of the piston chamber of the primary cylinder. The sum total effective cross-sectional area of all of the secondary cylinder piston chambers is greater than the corresponding cross-sectional area of the primary cylinder chamber to provide an output lifting force of the secondary cylinder(s) which is greater than the input force applied to a piston rod of the primary cylinder necessary to transfer hydraulic fluid from the primary cylinder to the secondary cylinder(s) to produce the enhanced output lifting force.

Abstract: A multi-part frame structure forming a mill housing for a rolling mill assembly is disclosed. The housing includes six separate and distinct components, namely a bottom separator member, a top separator member spaced above and disposed in registry with the bottom member and four elongated, upstanding columns of rectangular cross-section adjoining the top and bottom separator members to form a substantially rectangular opening for the passage of a steel strip therethrough during cold rolling operations. The top and bottom separator members are each of T-shaped cross-section defining a pair of tee arms which extend transversely across the frame and project forwardly and rearwardly from a tee leg. The tee arms of the top separator member are inserted in close spaced relation in traversely extending notches formed in upper end portions of the four columns.
