Abstract: During a positioning method for positioning a flat workpiece to be machined, in particular a sheet to be machined, for machining by means of a machining device, the workpiece is moved into a machining position by means of a controlled positioning drive with a positioning movement in a feed direction. During the positioning movement, the workpiece is supported on a workpiece support which, during the positioning movement of the workpiece, is moved, by means of a controlled support drive with a support movement in the feed direction. To avoid slippage between the workpiece and the workpiece support during the positioning movement of the workpiece, the support drive and the positioning drive are synchronized prior to the positioning movement of the workpiece by calibrating a control of the support drive and a control of the positioning drive.

Abstract: Typically, fluids used in fracking operations erode valve seats in the fluid end of the reciprocating pump. Thus, these valve seats must frequently be replaced by new valve seats. Accordingly, a remanufacturing process is disclosed that successively cleans and/or grinds manually or mechanically at least the carbide inserts from used valve seats until the inserts are reusable. This reduces material costs and promotes efficiency and sustainability.

Abstract: An echogenic needle may have at least one V-shaped spiral groove formed at its distal portion adjacent to its patient end. The walls of the groove are orthogonal to each other. The groove is titled at a given angle from a neutral position toward the proximal end of the needle so that when the needle is inserted into the patient at an insertion angle under ultrasound imaging, the ultrasound wave emitted from the ultrasound transducer is reflected in a substantially reverse direction back to the transducer by at least one wall of the spiral groove. A pair of crisscrossing grooves may be spirally wound about the distal portion of the needle with each groove being tilted to the given angle to enhance echogeneity. The echogeneity of the needle may also be enhanced by increasing the pitch density of each groove while maintaining the crisscrossing groves at their neutral position.
