Abstract: A system and a method to provide access to Internet content via telephone includes a control center that allows a user to select content sources, or modes, via a web browser interface. Once the modes are initially selected, the user calls the control center, is authenticated, and the user cycles through available modes using the telephone keypad. A desired mode is selected, again by keypad, and then items corresponding to that mode are presented to the user. Again using the keypad, the user selects a desired item and the system provides that content as audio to the user.

Abstract: A method of measuring the quality of a stick electrode used in forming the root bead of a pipe joint, which electrode has a wire diameter, a length substantially greater than 12 inches and an upper exposed rod head. The method comprises: preparing a standardized workpiece including two spaced plates with a groove between the plates having a set profile including a lower gap duplicating the root gap of the pipe joint and mounting the standardized workpiece on an incline with the groove facing upwardly where the incline is at a fixed known angle. Then a stick electrode of the type to be measured is selected and the rod head of the selected electrode is connected to the power lead of a DC power source set to a given output current correlated with the type of electrode.

Abstract: Stick welding electrode rating and ranking procedures are provided for determining stackability performance of stick electrodes for pipe welding operations. The rating technique involves performance of a standardized vertical down weld procedure using a stick electrode to form a weld bead in a test workpiece groove, in which the electrode is maintained during welding at a substantially constant angle relative to the workpiece groove. The electrode is advanced toward the groove at a slow speed to deposit molten metal in the groove while keeping the molten metal above the stick electrode end or the arc thereof without dripping. The resulting bead distance is measured along with the welding time and the stick electrode is rated according to a ratio of the weld time and the bead distance.
