    摘要： A process for treating natural gas or other methane-rich gas to remove excess nitrogen and carbon dioxide simultaneously. The invention relies on membrane separation using nitrogen/methane and carbon dioxide/methane selective membranes. The gas can typically be brought to pipeline specification for both components, without requiring the use of amine scrubbing or other acid gas removal technique. Where water vapor or hydrogen sulfide is present in the raw gas, these contaminants may also be removed to meet pipeline specification in a single operation.

    摘要： A separation process for recovering organic components from liquid streams. The process is a combination of pervaporation and decantation. In cases where the liquid stream contains the organic to be separated in dissolved form, the pervaporation step is used to concentrate the organic to a point above the solubility limit, so that a two-phase permeate is formed and then decanted. In cases where the liquid stream is a two-phase mixture, the decantation step is performed first, to remove the organic product phase, and the residue from the decanter is then treated by pervaporation. Embodiments using two decanters, particularly suited to handling feed streams containing multiple organic compounds of different properties, are included.

    摘要： A life-support system including a shelter, combined with equipment for sustaining a breathable atmosphere within the shelter. The breathable atmosphere is sustained by providing a supply of fresh air to the shelter, and removing carbon dioxide from the shelter. To provide the air supply, air containing a toxic agent is fed to a membrane separation unit. The membrane unit has a high selectivity to the permeation of oxygen over toxic agent and produces an oxygen-enriched permeate stream, while rejecting almost all of the toxic agent. The oxygen-enriched air is then passed through a unit containing a sorbent, such as activated carbon, to remove any remaining traces of toxic material before being fed to the shelter. The carbon dioxide content of the shelter air is kept below 1% either by sweeping the carbon dioxide away by maintaining a relatively high flow of air into and out of the shelter, or by withdrawing air from the shelter, treating it in a separate unit of equipment to remove carbon dioxide, and then returning the treated air to the shelter.

    摘要： Process and apparatus for the separation and purification of oxygen and nitrogen as well as a novel membrane useful therein are disclosed. The process utilizes novel facilitated transport membranes to selectively transport oxygen from one gaseous stream to another, leaving nitrogen as a byproduct. In the method, an oxygen carrier capable of reversibly binding molecular oxygen is dissolved in a polar organic membrane which separates a gaseous feed stream such as atmospheric air and a gaseous product stream. The feed stream is maintained at a sufficiently high oxygen pressure to keep the oxygen carrier in its oxygenated form at the interface of the feed stream with the membrane, while the product stream is maintained at a sufficiently low oxygen pressure to keep the carrier in its deoxygenated form at the interface of the product stream with the membrane. In an alternate mode of operation, the feed stream is maintained at a sufficiently low temperature and high oxygen pressure to keep the oxygen carrier in its oxygenated form at the interface of the feed stream with the membrane and the product stream is maintained at a sufficiently high temperature to keep the carrier in its deoxygenated form at the interface of the product stream with the membrane. Under such conditions, the carrier acts as a shuttle, picking up oxygen at the feed side of the membrane, diffusing across the membrane as the oxygenated complex, releasing oxygen to the product stream, and then diffusing back to the feed side to repeat the process. Exceptionally and unexpectedly high O.sub.2 /N.sub.2 selectivity, on the order of 10 to 30, is obtained, as well as exceptionally high oxygen permeability, on the order of 6 to 15.times.10.sup.-8 cm.sup.3 -cm/cm.sup.2 -sec-cmHg, as well as a long membrane life of in excess of 3 months, making the process commercially feasible.

    摘要： A processor for processing undeveloped photographic film discs carried on a rotatable spindle includes a conveyor for conveying the spindle intermittently from a first end of the processor along a generally horizontal conveyor path to each of a plurality of stations along the conveyor path. The intermittent conveying of the spindle by the conveyor is cyclical, with each cycle of the conveyor having a transport portion during which the spindle is conveyed from one station to another and a processing portion during which the spindle is positioned at one of the stations for processing. The spindle and film discs mounted thereon are rotated when positioned for processing at each station, and a rotation sensor at each station senses a failure of the spindle to be rotated. The processor also has a spindle sensor which senses the presence of the spindle adjacent the first end of the processor. An indicator responsive to the spindle sensor, the conveyor and the rotation sensor identifies any station at which the spindle is located and at which the rotation sensor senses the failure of the spindle to be rotated.
