摘要： A molten metal filter is disclosed having a carbon or carbon-thermite coating that reduces thermal shock to the filter, and protects the filter from corrosion from the metal or components and impurities in the metal, and prevents metal from freezing in the filter. A molten metal assembly suitable for casting molten metal is disclosed which comprises a filter for molten metal and means for molten metal flow passage leading through the filter. The means have surfaces defining a molten metal path. The filter has a coating of carbon or carbon in intimate contact with a thermite material on the surface of the filter. A process is disclosed for filtering molten metal which comprises passing molten metal through the above described coated filter.

摘要： A regeneratable adsorber for adsorbing adsorbable contaminates from a fluid stream containing same is disclosed. The adsorber includes an adsorber housing in which there is a fluid stream inlet and a fluid stream outlet. The adsorber also includes a plurality of adsorber chambers which are arranged in an indexable wheel configuration. Each chamber includes an electrically conductive adsorbent, such as a monolithic activated carbon, a set of electrical conductors in contact with the adsorbent, and an inlet and outlet. A chamber is either in contact with a source of contaminate fluid or a desorbent fluid used to regenerate the adsorber. The adsorber includes selectively indexed chambers for adsorption or desorption to provide continuous contaminate adsorption and regeneration.

摘要： The instant invention is directed at an apparatus for removing VOC's from an exhaust gas stream comprised of the following: a heatable adsorber located in the exhaust stream capable of desorption; and, an oxidizer structure having a lightoff temperature and located in the exhaust stream downstream from the adsorber structure. One particular embodiment of the apparatus comprises the following two elements: (1) a resistively heatable adsorber possessing an activated carbon phase located in the exhaust stream and having a desorption temperature; and, (2) an electrically heatable catalyst structure having a lightoff temperature and located in the exhaust stream downstream from the adsorber structure. The method enabled as a result of the development of the aforementioned apparatus, i.e., a method for removing VOC's from an exhaust stream, involves two essential steps: (1) causing exhaust gases from an exhaust gas stream to flow through an adsorber structure and an oxidizer while adsorbing an amount of VOC's; and, (2) heating the oxidizer to its lightoff temperature and desorbing the adsorbed VOC's and thereafter flowing the desorbed compounds through the oxidizer whereupon they are oxidized. One particular embodiment involves two essential steps: (1) flowing VOC-containing exhaust gases through an adsorber structure having an activated carbon phase and an electrically heatable catalyzed structure while adsorbing an amount of VOC's; and, (2) heating the catalyzed structure to its lightoff temperature, desorbing the adsorbed VOC's and thereafter flowing the desorbed compounds through the catalyzed structure whereupon the desorbed VOC's are oxidized.
