摘要： A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of a plurality of wicking fibers each of which comprising a strand with a hollow region impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. Each strand has a slot which connects the interior hollow region with an external surface. Capillary forces act on the carrier liquid such that the external surface is substantially dry and no appreciable adsorption of contaminates occurs on the external surface which would restrict the flow of an air stream through the filter media even after an extended period of use. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

摘要： A device for treating and conditioning engine coolant for use with an internal combustion engine includes a housing having an inlet and outlet and a filtering media and container carrying coolant treatment material located within the housing. Coolant passes through the filter, and then is exposed to the tip of a rod which erodes away to permit treatment material to be discharged in the coolant. As the corrosiveness of the coolant decreases, erosion of the rod is discontinued, so that additional treatment material is no longer discharged into the coolant. Accordingly, the corrosiveness of the coolant is controlled to within relatively narrow limits.

摘要： The preparation of syrups which contain a high glucose or maltose content may be effected in a two-step process. In the first step, a feedstock such as starch which has been pretreated with alpha-amylase to adjust the dextrose equivalent is contacted with an enzyme such as amyloglucosidase or beta-amylase immobilized on a solid support. The contact time is adjusted by correlating the residence time and the liquid hourly space velocity so as to provide a conversion percentage of starch in the range of from about 50% to 85%, thus avoiding the formation of undesired conversion products. The partially hydrolyzed reaction mixture from the enzyme treatment is then passed through an ultrafiltration membrane whereby the permeate comprising the high glucose or maltose content is recovered, while the retentate is recycled for admixture with the partially hydrolyzed reaction mixture or for further treatment with the immobilized enzyme.

摘要： Thermal deactivation of amyloglucosidase is substantially retarded at elevated pressures relative to atmospheric pressure. The productivity of glucose formation from amyloglucosidase-catalyzed hydrolysis of starch or partially hydrolyzed starch is significantly increased when the hydrolysis is performed at a pressure greater than about 500 psig.
