Abstract: Automated assessment of material-processing operations employs a deep feature-recognition network engine including a multilayer architecture. An input layer includes a plurality of nodes operative to receive measurement data comprising a work-profile data set representing a mechanical response over a displacement to a cold-working material-processing operation effecting the displacement, by a target portion of a workpiece. A plurality of layers are operative to produce activations of nodes based on feature sets derived from the measurement data, and to further produce an output based on the activations. The output represents an assessment of performance of the cold-working material-processing operation.

Abstract: The present invention provides a Siding Cutting Table, comprising a work surface specially designed for cutting aluminum or vinyl siding, as well as other construction materials such as wood and similar. Fabricated of a durable, heavy duty aluminum material, the Siding Cutting Table is generally rectangular in shape, measuring approximately nine feet eight inches in overall length, sixteen inches in width, and one and three-quarter inches in depth. A tri-sectioned unit, the product would consist of an “A” section with an enlarged surface on the left, a smaller “C” section in the center, and a similarly small “B” section on the right. These sections are separated by “K” pieces, or removable slots. The table also comes equipped with a table stabilizer beam located underneath the unit, as well as foldable legs that ensure easy transport and storage.

Abstract: A method and apparatus for use in a subterranean well is described. The apparatus typically includes a mandrel and a packing element. The mandrel may have an outer surface and a non-circular cross-section and the packing element may be arranged about the mandrel, the packing element having a non-circular inner surface matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus may include slips having cavities to facilitate removal of the apparatus. The apparatus also may include a valve for controlling upward fluid flow through a hollow mandrel. The valve may include a flapper having at least one tab to engage at least one recession in the mandrel such that rotation between the mandrel and the valve is precluded when the valve is in a closed position. The apparatus may further include a central member which is releaseably attached to the mandrel by a release mechanism.
