Abstract: A process where the need to circulate hydrogen through the catalyst is eliminated. This is accomplished by mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is "high" relative to the oil feed. The type and amount of diluent added, as well as the reactor conditions, can be set so that all of the hydrogen required in the hydroprocessing reactions is available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required, therefore, hydrogen recirculation is avoided and trickle bed operation of the reactor is avoided. Therefore, the large trickle bed reactors can be replaced by much smaller tubular reactor.

Abstract: A roller board (16) for organizing a plurality of filaments (14) from spools (28) for delivery to a collection point, includes a first plurality of rollers (40) arranged to form spaces (42) therebetween, and a second plurality of rollers (44), each pivotable at one end (80) positioned proximate the first plurality of rollers (40), the second plurality of rollers (44) oriented substantially perpendicular to the first plurality of rollers, wherein the plurality of filaments (14) are individually positioned in the spaces and the second plurality of rollers are selectively pivoted to enclose the filaments.

Abstract: Comb section pair of an articulating expansion comb for processing textile threads or filamentary wires, including a first and a second comb section pivotally joined together at an axis of rotation in the vicinity of an end of each comb section, a group of comb needles disposed on each comb section in a respective alignment plane, each of the comb needles being mutually spaced apart by a given comb needle division, the alignment planes intersecting at the axis of rotation, the axis of rotation extending exclusively through the comb needle group of the first comb section, a last comb needle of the comb needle group on the first comb section being disposed at least one comb needle division beyond the axis of rotation toward the end of the first comb section, a first comb needle disposed closest to the end of the second comb section being at most one comb needle division farther from the axis of rotation than the last comb needle of the first comb section.
