Abstract: A contact bar and related techniques allow enhanced electrolytic refining of metals, e.g. avoiding or reducing electrical short circuits. The contact bar is adapted to rest on an insulating capping board for contacting symmetrical electrodes to provide locations for electrical contact therewith. The contact bar includes a central portion laying on the capping board and branch portions extending laterally outward from the central portion, such that the branch portions fit in between seats of the capping board. The contact bar may include a retention member enabling to reduce lateral movement of the electrodes, and may include a plurality of apertures to engage corresponding holding arms of the capping board. There may be a plurality of adjacent similar contact bar segments.

Abstract: A hook, a hold down strap and a method for holding down an underground tank. The hook includes a base portion connectable to the hold down strap; a curved portion extending from the base portion and defining a concave receiving area having an entrance sized and configured for receiving an anchor element. The hook includes at least one hooking aid member being a flexible member or an extension member. The flexible member extends across the entrance of the concave receiving area and is sized and configured to bend from a closed position to an open position such that, when the anchor element traverses the entrance, the flexible member bends from the closed position toward the concave receiving area to the open position, thus allowing the anchor element to enter the concave receiving area. The extension member extends from the curved portion beyond the entrance of the concave receiving area.
Abstract translation: 一个钩子，一个按扣和一个压住地下水箱的方法。 钩包括可连接到压紧带的基部; 从所述基部延伸并且限定具有入口的凹入的接收区域的弯曲部分，所述入口的大小和构造用于容纳锚固元件。 钩包括至少一个钩子辅助构件，其是柔性构件或延伸构件。 柔性构件延伸穿过凹接收区域的入口并且其尺寸和构造成从关闭位置弯曲到打开位置，使得当锚定元件穿过入口时，柔性构件从关闭位置弯曲到凹入接收 区域到打开位置，从而允许锚固元件进入凹形接收区域。 延伸构件从弯曲部分延伸超出凹入接收区域的入口。

Abstract: Various anchors and methods for anchoring an underground storage tank are provided. The anchor includes a base and at least one retention mechanism connected to the base for retaining various configurations of hooks and straps for holding the tank. The retention mechanism includes an opening and a retention member that is configured to open or close the opening by displacing or collapsing said retention member. The anchor may include a composite base having a footing and a spine extending upwardly from the footing so as to define footing portions on either side of the spine. The footing and the spine may have a composite composition that includes a matrix material and a reinforcement structure embedded within the matrix material. The retention mechanism may be connected to the spine of the composite base for retaining a hook for anchoring the underground storage tank.
