The present invention is directed to a process for the preparation of crystalline anionic clay-containing bodies from sources comprising an aluminum source and a magnesium source comprising the steps of:. The wire pull attachment includes an insert, a basket adapted to receive and secure an article therein, and a swivel assembly interconnecting the insert and basket such that the swivel assembly allows the basket to move freely relative to the insert. Here, the bearing housing comprises a flange extending to have a protruded part and a recessed part in a radial direction. A first current shunting diode has an anode coupled to the pad and a cathode coupled to a first voltage source.
