The electrostatic classifier and separator is supported by a housing and includes a corona classifier section for classifying particulate materials according to size. Corona element supplies mobile ions for bombarding particulate materials dropping down a passageway from a reservoir. A splitter and screen may be included in the passageway to direct particulate materials into respective fractions. First separator section receives fine to middle size fractions and second separator section receives middle to coarse size fractions. A support frame having adjustable slots supports a plurality of static electrodes. Corona element for emitting a corona charge is spaced generally in a first quadrant of first separator section. A rotatable brush and an alternating current wiper may be included for removing fine to middle size nonconductive fractions from first separator section. Additional splitter and/or a baffle may be included to help guide particulate material fractions into respective containers, onto a conveyor belt or the like.

A D. C. voltage altering device includes at least one spark induction power conditioner including a first electrode connectable to a high voltage D. C. power source and a second electrode spaced from the first electrode and forming a discharging gap therebetween. The second electrode is connectable to a predetermined section of a physical separator and at least one of the electrodes is selectively positionable for altering spatial distance between same. The power conditioner induces a predetermined large amplitude, high frequency current ripple to the second electrode for creating a fluctuating voltage and fluctuating electrostatic field and maintaining continuous current flow through the gap without reversal of polarity. The spark induction power conditioner further includes a dielectric base for housing the electrodes and a plurality of fastening members threadably positionable through the base and engageable with the electrodes so that the discharging gap between the electrodes can be selectively adjusted.

A washing liquid distribution system includes a spiral separator having a plurality of flights, each flight including at least one receiving cup for distributing liquid onto the flight. A directional outlet nozzle is mounted in cup for providing a horizontal outlet stream of a liquid. The nozzle is both rotatably and releasably mounted in a recess at the bottom of the cup. One or more outlet openings in a variety of geometric shapes to provide the desired outlet stream of wash liquid.

System and method for a continuous process for separating particles according to their magnetic properties such as Curie point includes a feed of hot particles having different magnetic properties on a moving surface spaced above a stationary magnetic assembly. The temperature of the bed of particles is controlled to enable selective separation of different factions of particles based upon the temperature of the particles. The magnets are maintained substantially below their Curie point. Gaseous nitrogen is fed into and from the inside of the magnetic assembly to enhance the cooling of the magnetic assembly and to inhibit oxidation. The gas exits through high temperature bearings to inhibit debris therein. A thermal shield is placed between the moving surface and the magnets and below tubes carrying a cooling fluid to maintain magnets substantially below their Curie point. The entire process is contained with an inert gas-purged cabinet.

A material separator system and method for magnetically separating components of feedstock by directing the feedstock onto a thin rotating shell enclosing one or more rotating magnetic rolls capable of riding upon the interior of the shell. In one embodiment, a cam-and-bearing arrangement is used to permit the magnetic roll and shell each to rotate on its own independent axis. This provides the ability to adjust clearance, the line of contact, and the degree of contact between the magnetic roll and the shell. In another embodiment, a different arrangement provides the same capabilities. The system can be configured to drive a magnetic roll, which then drives the shell, or it can be configured to drive the shell, which then drives the magnetic roll. The system can also be configured as a retreater for retreating feedstock.

An accommodation ladder includes a body having opposite sides, an upper, and rear and bottom surfaces. The body is formed of a compressible material, such as dense foam material, and the upper surface of the body forms a staircase with a plurality of steps. Spaced stanchions extend upwardly from the staircase and stanchion pipes extend through the body and receive lines therethrough to secure the body to a marine structure. The spaced stanchions are adapted to accommodate a plurality of releasable safety lines therebetween. A method of facilitating access between adjacent first and second marine structures includes arranging the staircase accommodation ladder between the structures, the accommodation ladder being a fender between such structures.

An aluminum mold for the interior surfaces of one or more spirals is rotated at a temperature sufficient to melt a weldable plastic such as LLDP or HDP plastic in a predetermined amount sprinkled thereon. Plastic powder not melted is recovered and redeposited until all the plastic powder is melted. The mold or molds are then cooled and the formed spiral is removed.

A mold for the interior surfaces of one or more spirals is rotated and heated to a temperature sufficient to melt a weldable plastic such as LLDP or HDP plastic in a predetermined amount deposited thereon. Plastic powder not melted is recovered and redeposited until all the plastic powder is melted. The mold or molds are then actively cooled and the formed spiral is removed. An insulation layer is used to improve heating and cooling efficiency, and to control the areas where plastic is deposited. A cover closes the back of the mold.
