Abstract: Smith-Strain 19-6 CHARGE COUPLED DEVICE     Abstract of the disclosure A Charge Coupled Device (CCD) structure employing two levels of electrode metallization.  The field plate electrodes are arranged in pairs with the second one of each pair partially overlapping and insulated from the first one of its pair and the first one of the next pair.  The structure can be operated two-phase with four electrodes per bit and three-phase with three electrodes per bit by providing suitable amounts of electrode overlap and suitable drive circuitry.  A particularly advantageous mode of two-phase operation with four electrodes per bit is enabled by providing asymmetrical overlapping of electrodes, the second electrode of each pair overlapping the first electrode of its pair more than the first electrode of the next pair.     8  electrodes per bit and three-phase with three electrodes

Abstract: ABSTRACT OF THE DISCLOSURE     In accordance with an illustrative embodiment of the present invention, there is disclosed herein a device for anchoring downhole apparatus such as a safety valve in a tubing landing nipple, and more particularly a running tool for lowering the anchoring device at the end of a wire line into the tubing. The anchoring device comprises a body member that carries locking dogs which are shifted outwardly and engaged by the longitudinal movement of an expander mandrel.  An expansible ring that is maintained on the mandrel by shear pins functions to lock the mandrel in the engaged position of the dogs. The running tool comprises a control sleeve having pivotally mounted connecting keys which remain engaged with the mandrel until the locking dogs are properly engaged and which then are released automatically from the mandrel. A safety shear pin makes it possible to free the running tool from the anchoring device in the event of incorrect anchoring of the latter and, when sheared, provides a "tell-tale" of incorrect installation.
