摘要:
This invention provides a shaped ceramic composite article comprising ceramic oxide fiber(s), a first coating comprising a carbonaceous matrix which includes boron nitride particles in contact therewith, and a second coating comprising silicon carbide. The inventive composite article is useful in applications requiring good heat resistance and mechanical properties, such as gas fired radiant burner tubes, gas burner nozzle liners, heat exchangers, thermowells, core busters or flame dispersers, and other gas fired furnace components.
摘要:
A protected towel assembly for providing the user thereof with a protectively enclosed towel. The assembly may include a towel, an enclosure and a connector connecting the towel and enclosure for cooperative suspension from a selected object. The enclosure is formed from a sheet of water impervious material which, when folded, provides a protective enclosure around the towel which may be opened along a side to expose the towel for use.

A valve including a valve body having a bore and a spindle received in the bore, the spindle being actuatable to open and close the valve. A compression gland seal is provided about the spindle for compression between the spindle and the bore. A first seal ring is provided about the spindle at a position spaced along the spindle from the gland seal, and provides a seal between the spindle and the bore of the valve body. A second seal ring is provided about the spindle at a position spaced along the spindle from the gland seal and the first seal ring, and provides a further seal between the spindle and the bore of the valve body.

A gas generant composition used in pressure activated restraint system devices such as micro-gas generator applications such as seat belt pretensioners is provided. The gas generant composition includes a potassium perchlorate gas generant additive in addition to a non-azide nitrogen-containing gas generating fuel, a metal ammine nitrate oxidizer, and a metal oxide burn rate enhancing and slag formation additive. The gas generant composition desirably has improved ignitability as compared to a similar composition without the potassium perchlorate gas generant additive. The gas generant composition also desirably produces or results in effluents having either or both reduced carbon monoxide and NOx contents as compared to the effluent produced or resulting from a similar composition but without the inclusion of the potassium perchlorate gas generant additive.

摘要:
In order to prevent hazardous substances--oils, fuels, deicing liquids--spilled onto the ground or pavement, e.g. at an airport, to enter storm sewer system with subsequent contamination of the environment, a catchbasin structure is provided comprising a receptacle with an opening closable with a valve in a manner to seal off the entry of the liquid into the storm sewer system. Instead, the liquid can be kept in the receptacle and on the ground in the area adjacent to the catchbasin, or selectively directed to a storage tank system for treatment or recovery.

A filter cartridge utilized in filtering dry cleaning fluid includes an annular, generally cylindrical outer member which carries a tubular, pleated paper filter and an annular, generally cylindrical inner member which carries a particulate sorbant mass therewithin. In conventional use, dry cleaning fluid is caused to flow radially inwardly through the filter cartridge, first passing through the pleated paper filter and then through the sorbant mass. The fluid exits through a longitudinal passageway extending axially through the cartridge. After the filter cartridge has been spent, the inner member may be slidably removed from the outer member in order that the considerable weight of the spent cartridge may be removed from the filter tank in two separate operations.
