A mobile system for manufacturing and installing rock reinforcing members in mining and tunnel construction applications where a plurality of holes are drilled into the rock and each hole receives a reinforcing member and grout. Conductive coils are made with a magnetostrictive covering that can comprise a film or other coating. The rotation of the table moves the robot from one workstation to the next while carrying a part to be processed. A spring is provided on a member formed in one body with the valve seat portion, for positioning the valve to the valve seat portion, wherein clearance volume of the discharge port is reduced, so as to improve the performances thereof. The invention also relates to methods for processing messages and methods for training message processing systems. These techniques can be used to delay or defer the loading of values into the resource dictionary until the values are actually needed or requested by an application.
