Abstract: Co-production a product anode grade coke and a product fuel grade coke is done using a system configured to implement a method that includes: directing an anode grade coker charge material from a tower to a first coke drum set; generating the product anode grade coke using the first coke drum set while directing a first vapor stream from the first coker drum set to the tower; directing a fuel grade coker charge material from a fractionator to a second coke drum set; generating the product fuel grade coke using the second coke drum set while directing a second vapor stream from the second coke drum set to the fractionator; and directing a third vapor stream from the tower to the fractionator while generating the product anode grade coke using the first coke drum set and generating the product fuel grade coke using the second coke drum set.

Abstract: A system for separating liquids of different densities employs a collector shell (17) made up of smooth lines and curvatures. A fairing creates and controls the flow of the liquids (for example water and oil) by gathering, capturing and isolating one liquid beneath the surface of the other liquid (24). The trapped and water pressurized oil is extracted and transferred to a storage container (21). One embodiment, the collector shell (17) is a simple design yet complex in achieving a workable shape that can accomplish all of the above using a small number of moving parts all of which, with the possible exception of the collector shell (17) and the elevator screw (12) are off the shelf items. The collector shell (17) inherently suppresses turbulence. The accumulation of oil captured in the collector bowl (17d) remains in a state of semi-suspension in both rough and normal surface conditions. The only movement of the oil is in a vertical direction when the elevator screw (12) is in motion.

Abstract: The composite plastic lens includes an anterior plastic lens having a first corrective feature and a posterior plastic lens having a second corrective feature. One of the lenses, preferably the anterior lens, may have an optical center axis that is decentered with respect to the geometric center axis of the lens. That lens is prism-shaped. Both lenses are disposed atop one another such that when their optical center axes are combined, the resultant optical center axis or principal axis of the composite lens is at a predetermined position relative to the bifocal, multifocal or progressive lens feature carried by the anterior lens. The anterior and posterior lenses are joined together by an adhesive that bonds opposing, etched surfaces of those lenses. The method of making the composite plastic lens includes, in one embodiment, the steps of etching the front and rear surfaces of the posterior and anterior lenses and bonding those etched surfaces together with an adhesive.

The method of making the composite plastic lens includes, in one embodiment, the steps of etching the front and rear surfaces of the posterior and anterior lenses and bonding those etched surfaces together with an adhesive. Another method of making the composite plastic lens includes heating the lenses prior to bonding them together for a time such that the posterior and anterior lenses return to their original shape and curvature.
