Abstract: The disclosed technology generally relates to welding technologies and more particularly to electrodes for shielded metal arc welding. In one aspect the electrode includes an electrode core having an electrode core tip and a coating formed around the electrode core. The electrode core tip comprises an end surface, a tapered surface, and one or more surface features formed on the tapered surface. The surface area of the electrode core tip is greater than the surface area of a reference electrode core tip that is the same as the electrode core tip except for the presence of the one or more surface features. The coating is adhered to the tapered surface and at least partially covers each of the one or more surface features.

Abstract: The disclosed technology generally relates to welding technologies and more particularly to electrodes for shielded metal arc welding. In one aspect, a welding electrode comprises an electrode core and a coating formed around the electrode core. The electrode core has a centerline axis that extends along its length and comprises an electrode core body and an electrode core tip. The electrode core body has a circular cross-section having a radius. The electrode core tip has two or more recessed portions and two or more unrecessed portions. The two or more recessed portions extend along a length of the electrode core tip and a radial distance between the centerline axis and a surface of one of the recessed portions is less than a length of the radius. The coating comprises a flux material.

Abstract: Methods and devices for presenting application program information may include receiving an indication corresponding to a selection of a first user interface element associated with an application program package that includes a set of package information. Moreover, the methods and devices may retrieve a subset of package information from the set of package information by executing one or more packaging application program interfaces (APIs) to extract the subset of package information from the set of package information.

Abstract: The present invention is directed to systems for prolonging battery life, such as maintaining battery cell temperatures in battery packs within specified limits, providing vibration and shock resistance, and/or electrically isolating groups of batteries from nearby conductive surfaces.

Abstract: A system for managing metadata information comprising a database for storing the metadata in formation; a central processing core, connected to the database, for monitoring and controlling access of the database; a process dispatcher for receiving the metadata information and transmitting the metadata information to the database via the central processing core; and a user interface for displaying the metadata information connected to the central processing core.
