Abstract: Parallel chromatography systems and continuous manufacturing methods are described herein that utilize two or more chromatography column skids having columns operating in parallel with automation controls governing which column to load at a given time.

Abstract: A multiple mode headbox is provided including a support surface, two or more chambers, and an adjustable roof. Each chamber includes a plurality of nozzles adapted to optionally supply papermaking fibers to the support surface. The adjustable roof is operably configured to adjust over a range of movement such that it defines a forming zone between the support surface and at least one chamber in a first mode, and between said support surface and at least one different said chamber in a second mode.

Abstract: A gravity-operated apparatus for sequentially dispensing sheet material from rolls of sheet material. The apparatus includes a housing having an opening; a rotatable turret; cantilevered spindles adapted to receive a roll of sheet material; and a limit gate. Each spindle extends from a distal portion of the turret so the weight of a full roll of sheet material on the spindle urges the turret to rotate placing a full roll of sheet material at a dispensing position. The limit gate is positioned to impede rotation of the turret when the limit gate encounters a spindle containing a roll of sheet material that is less than substantially depleted.

Abstract: An elongated in-the-field relatively long workpiece supporting frame provided with a wood working tool is formed by a pair of upright end frames, horizontally supporting a pair of tracks therebetween.The tracks in turn support a carriage movable along the tracks toward or away from either of the end frames.A workpiece extending between the work frames is supported by horizontal panel members on the frames while the workpiece lies on the work table of the wood working tool.

Abstract: A solar energy system in which a heat transferring liquid captures heat in solar collectors and stores it in a storage tank is disclosed. A pump moves heat transferring liquid from the storage tank to the collectors and into a drain-back module only when a predetermined activation temperature is achieved. The pump then inactivates allowing heat transferring liquid within the collectors to heat. When the pump initially inactivates, a siphon or draining cycle is formed which moves heat transferring liquid from the drain-back module to the storage tank. Gas within the storage tank replaces heat transferring liquid in the collectors through the drain-back module to achieve drain-back. However, the siphon or draining operation must first cause heat transferring liquid within the drain-back module to fall below a drain-back feed point. Thus, the solar energy system delays drain-back until after the siphon or draining operation is completed.

Abstract: Disclosed is an improved ginning system incorporating a roller gin and a feeder for the same. Means is provided for presenting the cotton to the roller gin substantially one lock at a time. Incorporated in the gin is means to move the ginning roller into and out of ginning relation to the ginning knife, and means is provided in the system to cause the ginning roller to move out of ginning relation to the knife whenever there is less than a predetermined amount of seed cotton in the feeder.
