Abstract: A multi-tray distillation unit having a separator for de-entraining liquid particles which are picked up by an upwardly flowing gaseous stream which is flowing countercurrent to a descending liquid flow in the unit. The separator which is placed above the contact plate on which the gas contacts the liquid, comprises vertically spaced tiers of elongated, substantially horizontal open-topped liquid collector channels arrayed in parallel rows transversely to the flow of the gas. The liquid collector channels are vertically staggered to deflect the gas flow from a lower tier level through the gaps between the collection channels of an upper tier and around the channels so as to cause the entrained liquid particles to separate from the gaseous stream by inertia into the channels of the lower tier. The collected liquid is then returned through a liquid downcorner to a contact plate.

Abstract: This invention is directed to a cyclonic vapor/liquid contacting device and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall, where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone.

Abstract: Inherent defects in the angular relationship between facets of a rotating polygonal mirror used to sequentially scan a beam of radiation are corrected by an optical reflecting or refracting element pivotally mounted in the path of the radiation. With the use of electromechanical devices energized by timed electrical signals of appropriate value, the mirror or refracting element is pivoted to correct the scanning errors caused by angular defects in the rotating mirror. The effect of variations in the angles between facets of the polygonal mirror are also corrected by an electronic circuit which includes a delay device capable of delaying the scanning by a predetermined amount. Control means for the electromechanical devices and for the delay device are pre-programmed so as to make the proper adjustments for each facet of the rotating polygonal mirror.
