    Abstract: OIL, SOLID PARTICLES SUCH AS BIOLOGICAL SLIME AND FLOATING DEBRIS, ETC., ARE REMOVED FROM WATER BY AN APPARATUS INCLUDING ENDLESS CHAIN MEANS MADE UP OF A SERIES OF INTERCONNECTED FORAMINOUS CHAMBERS HOLDING A REGENERABLE POROUS FILTER MATERIAL SUCH AS POLYURETHANE. PREFERABLY, THE FILTER MATERIAL HAS AN OUTER LARGE PORE SECTION AND AN INNER SMALL PORE SECTION. A PLURALITY OF BUCKETS ARE ATTACHED TO THE CHAIN MEANS AND, AS THE CHAIN MEANS MOVES THROUGH A CLOSED LOOP PATH, THESE BUCKETS CATCH DEBRIS AND DUMP IT INTO A HOLDING BIN. SIMULTANEOUSLY, THE FILTER MARIAL ABSORBS SURFACE AND SUBSURFACE OIL AND THE LIKE FROM WATER TRAVELING THROUGH THE FILTER MATERIAL. THE FILTER MATERIAL IS REGENERATED BY SQEEZING THE FILTER MATERIAL TO RELEASE THE OIL.

    Abstract: The method comprises introducing a petroleum hydrocarbon stream containing metals, hydrocarbons having coke-forming tendencies, and residual-type hydrocarbons into the fractionating column associated with a catalytic cracking unit of the refinery. The introduction of the petroleum hydrocarbon stream into the fractionating column is accomplished at a point in the fractionating column above which substantially all of the recycle material is withdrawn from the fractionating column; it may comprise the injection of the petroleum hydrocarbon stream into the baffle section of the fractionating column. The petroleum hydrocarbon stream may be a crude oil, may be desalted, and may have been treated for the removal of any amount of water which is contained therein and which would appreciably and suddenly increase the amount of liquid water being added to the fractionating column.

    Abstract: A non-destructive test is provided for determining the ability of a metal coating to adhere to the plastic substrate of a metallized plastic article comprising determining the difference between two separate contact angle values, the first being obtained by measuring the contact angle formed by a drop of liquid resting on a specimen plastic substrate prior to etching said substrate and the second being obtained by measuring the contact angle formed by a drop of liquid resting on an etched plastic substrate. Contact angle values are easily measurable parameters which indicate platability and therefore are valuable in the electroplating of plastics.
