Abstract: A process for the recovery of hydrocarbon vapors from an air-hydrocarbon mixture wherein the inlet air-hydrocarbon mixture is passed to an absorber vessel in which is fed a vacuum flashed liquid hydrocarbon absorbent to produce an absorber overhead gas stream which is passed to a solid absorbent bed. Once saturated, the adsorbed hydrocarbon on the solid adsorbent bed is removed by liquid vacuum pump regeneration, separated from the pump liquid, and returned to the system for use. Hydrocarbon free air is vented from the solid adsorbent bed during the adsorption mode.

Abstract: A post installation skylight assembly is presented in which a backup frame with an access opening is rested upon underlying secondary structural members prior to installation of a roof panel over and nesting with the backup frame, post removal of a medial position of the roof panel to expose the access opening, and positioning a translucent pane member over the opening frame to cover the access opening.

Abstract: A process for the recovery of hydrocarbon vapors from an air-hydrocarbon mixture expelled as a result of storage breathing or loading of a vented hydrocarbon vessel. An inlet air-hydrocarbon mixture is passed to a first absorber in which is fed a vacuum flashed liquid hydrocarbon absorbent to produce a first absorber overhead gas which is passed to a solid absorbent bed. Once saturated, the absorbed hydrocarbon on the solid absorbent is removed by vacuum regeneration, separated from liquid supplied by the liquid ring pump creating the vacuum, and passed to a second absorber vessel where fresh liquid hydrocarbon absorbent is contacted therewith to produce a second absorber overhead gas which is combined with the incoming inlet air-hydrocarbon mixture to pass therewith to the first absorber. Hydrocarbon free air is vented from the solid absorbent bed during the adsorption mode.

Abstract: A method and apparatus for cutting predetermined lengths of panels from a continuous strip of flexible material and for forming the lengths of panel members to have a preselected panel profile. The strip is reel fed to a first strip driving station which drives the strip through a shearing station, over a hump table, to a second strip driving station and through a strip forming station. In sequence, the second strip driving station brakes the leading portion of the strip to effect a strip hump over the hump table, which is detected by a protoelectric sensor for hump height and signals the first strip driving station to vary its feed rate to maintain the hump; the second driving station is then signaled to commence driving the lead portion of the strip to the strip forming station.
