摘要： A vent insert with an integral carbon-to-carbon composite filter element is used to vent enclosures such as drums and convenience cans containing transuranic materials which generate hydrogen. The vent inserts do not utilize adhesive to retain filter elements therein but rather utilize a housing having a filter element support with a knife edge to form a seal and a press fitted lid. Both the housing and lid are formed of corrosion resistant HASTELLOY® C-22® alloy. The vent inserts resist HCl corrosion as well as corrosion induced by nitric acid and chlorinated solvents.

摘要： The invention relates to a filter cloth intended for a filter which has a variable volume and is based on diaphragm extrusion, particularly for a Larox®-type vertical pressure filter. The filtering properties of the filter cloth (5) are substantially similar in both directions through the cloth since slurry containing liquid and solids is alternately placed on the different sides of the filter cloth. The filter cloth of the invention comprises a middle layer (15) and protective layers (16a, 16b; 17a, 17b) provided on both outer surfaces of the middle layer. The middle layer can have e.g. a woven structure, and the protective layers may be batt fiber layers attached to the middle layer by needling. According to a preferred embodiment of the invention, the protective layers according to the invention are denser than the middle layer.

摘要： A non-woven web of fibrous material containing a reactive particulate material is made using the wet laid, or preferably foam, process. First and second fibrous webs are made using the wet laid or foam process, and a liquid or foam slurry including reactive particulate material is provided between the webs so as to provide a composite web. Liquid, or foam and liquid, are withdrawn from the composite web and then the composite web is dried so as to produce a final non-woven web with reactive material having substantially optimum reactivity (that is the reactive material loses a minimum amount reactivity during the web production process). The webs and slurry may be made using substantially pure water, and the particulate part of the reactive material is mixed with the foam or liquid slurry no more than about ten seconds before the liquid and/or foam are withdrawn from the composite web. Activated carbon and titanium dioxide are two particularly desirable reactive particulates; the reactive loading is at least 0.01 g/cm3, and the air permeability of the final web is at least 3000 liters per square meter per second.

摘要： A novel, high performance yet permeable, tough, fibrous structure, and a process for making the structure are disclosed. The fibrous structure includes a stabilized microstructure of improved uniformity of fiber and particulate distribution. Beneficially, the fibrous structure is of improved structural integrity and stiffness, as a result of being reduced in thickness. The process includes the steps of dry forming a fibrous web including crimped staple composite fibers, thereafter distributing and entrapping the functional particles in the web, and thereafter heating the fibrous web to form a microstructure-stabilized fibrous web. According to the process, the microstructure-stabilized fibrous web is thereafter by an additional heat treating step carried out without application of pressure to the web, heated to a thermoforming temperature, and thereafter the heated web is reduced in thickness and yet microstructural relative geometry is maintained. IR heat may be used. A nip gap is advantageously used to reduce the heated web in thickness.
