    Abstract: A method for forming a large metallic component, a friction stir welded component and a friction stir welded blank are provided. The method includes positioning a first metallic plate and a second metallic plate in an abutting arrangement. The first metallic plate and the second metallic plate have corresponding faying surfaces at a point of abutment. A backing plate is attached spanning the point of abutment adjacent the faying surfaces. The first metallic plate is friction stir welded to the second metallic plate to form a friction stir weld along the faying surfaces. The backing plate receives an end of a friction stir welding tool curing the friction stir welding. The backing plate is removed to form a welded blank. The welded blank is formed into a component form. The component is heat treated and aged to form the large metallic component. The friction stir weld in the welded blank has a stable microstructure having little or no abnormal grain growth during elevated temperature forming, heat treatment and aging.

    Abstract: A computer-implemented method for positioning a workpiece for a computer numerical controlled (CNC) process includes: causing a positioner to move an end effector to an initial position; receiving first position information associated with a first optical signal transmitted from a first optical target coupled to the workpiece; receiving second position information associated with a second optical signal transmitted from a second optical target coupled to the end effector; determining an offset between the initial position and a target position for the end effector based on the first position information and the second position information; and causing the positioner to move the end effector to a final position based on the offset.

    Abstract: A particulate feeding apparatus for applying particulate, such as super-absorbent materials, to a substrate, such as a fibrous web. A feeder tube for the powder and a rotary gate valve, including one or more holes is provided. This structure may then intermittently feed particulate to an eductor or venturi nozzle. The rotary valve provides an intermittent supply of particulate to a relatively low-pressure zone at the nozzle formed by the venturi action of the passing air stream and the particulate may be distributed precisely where desired. A process for delivering powder to a substrate in precise amounts and distribution patterns is also disclosed.

    Abstract: An ultra low temperature freezer evaporator (ULT) apparatus that has a triple feed capillary tube system. The ULT apparatus prevents the low stage compressor from running in a vacuum. The invention significantly reduces the “pull down” time. Further, the ULT freezer evaporator apparatus significantly increases the transfer area between the evaporator tubing and the contact surface on the unit to assist the transfer of heat from the refrigerated unit through the condenser to the surrounding room.
