Abstract: A board edging infeed optimization system is described for feeding a board into an edging device capable of longitudinally cutting the wane edges of the board.  The infeed system is equipped with a  conveyor which transversely advances the board along a straight path, a conventional optical scanning station,  and a computer which calculates a longitudinal reference datum line and a preferred edging path for the board and places movable positioning pegs at a predetermined distance away from the preferred edging path.  A  novel  mechanism is used to seize and transport the board further along the path by the predetermined  distance  so  that the board's  longitudinal  reference datum line  is placed colinear with the preferred infeed line into the edging device.  The novel mechanism is characterized by the use of rotatable eccentric arm which sequentially advance and retract movable clamping jaws.  After the board is placed along  its  preferred  infeed  line,  grip  rollers  can longitudinally feed  it into the edging device.   If required, friction shoes may be installed directly above the general location of the positioning pegs to ensure that the advancing boards will sequentially come to rest in abutment with the positioning pegs and will not bounce or slide out of position.  The eccentric arm assembly can optionally be provided with fluid operated telescopic arms which can be quickly adjusted to allow the infeed optimization system to selectively feed boards to a plurality of adjacent edging devices.

Abstract: An electrical isolation device is connected at input terminals in lines between a structure to be cathodically protected and a ground, or between two cathodically protected structures, to block selected low levels of DC voltage while freely conducting normal AC currents and all fault currents.  The device has two diode stacks, formed of layers, and the stacks are connected in parallel with one another in opposite polarity and in parallel with a capacitor across the input terminals of the device.  Each diode layer include a junction wafer and a conducting metal disk.  The layers in each stack are preferably pressed tightly together and to metal bus conductors by a clamp to maximize the contact of the diode layers to each other and to the conductors to minimize contact resistance.  AC currents are conducted (e.g., to ground) through the capacitor while low level DC voltages are blocked by the cumulative threshold voltages of the plural diode layers connected in series in each of the stacks.  When a large AC or DC fault occurs, the voltage across a stack exceeds the turn-on voltage of the stack so that fault currents are conducted to ground through the diode stacks.  The number of diodes in each stack may be selected to provide a continued cathodic protection voltage in the presence of large AC fault currents.  The diode stacks may also be connected together in a bridge structure to reduce the number of diodes required.
