Abstract: This invention provides a vapor-tight luminaire with a housing that defines a continuous and unbroken sealed tubular lens extending in a longitudinal direction. The housing includes a pair of end cap structures removably and sealably mounted on each of opposing respective housing ends. The housing removably supports a lamp assembly that can include various reflector arrangements. The lamp assembly can include fluorescent tubular lamps and can include electronics, such as a ballast circuit. Illustratively, a supporting rail suspended from each of the opposing housing ends by respective posts slidably supports the lamp assembly. In this manner each of the housing and the lamp assembly are constructed and arranged to allow the lamp assembly to be passed into and out of the housing along the supporting rail when at least one of the end cap structures is removed from the respective one of the housing ends.

Abstract: This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap.

Abstract: A method for treating the disease state in mammals caused by mammalian nasal and sinus cells involved in the inflammatory response is disclosed. Mammalian nasal and sinus cells participating in the inflammatory response are contacted with an inflammatory response mediator which reduces the undesired inflammatory response and is an antioxidant. The inflammatory response mediator may further provide a cellular energy source and be a building block in the cellular synthesis of other cellular components. Compositions for reducing and treating undesired inflammatory response are also disclosed.

Abstract: A flexible accessory bag (35) for releasable attachment to a lid or cover (20) on a container (10), such as an ice chest or cooler, which is pivoted between open and closed positions of the container (10). The accessory bag (35) has a pair of opposed ends (36, 38) which are secured by elastic bands (54, 56) to opposed lid ends (27, 28) and a pair of zippered pockets (40, 42) secured to the bag ends (36, 38) extend over the lid (20).

Abstract: A liquid slurry of submicron particles of hexabromobenzene is prepared by vaporizing hexabromobenzene in a first zone, transporting the vapors to a second zone by use of an inert carrier gas, condensing the vapors in a second zone so as to form a liquid slurry, and thereafter recovering the slurry formed. The product particles are particularly effective when used as a fire retardant in an acrylic fiber having high luster requirements.

Abstract: Tetrakis-(hydroxymethyl)-phosphonium salts (TKX salts) are produced by countercurrent contacting of phosphine gas with aqueous solution of formaldehyde and a selected acid in a multistage reactor. In the countercurrent contacting reactor, phosphine is practically exhausted at the liquid feed end while at the other end the formaldehyde is exhausted. When the formaldehyde end point is exceeded in the reactor, phosphine reacts with product TKX salt to produce trihydroxymethylphosphine (THP). Product taken from the reactor is adjusted to end point by addition of formaldehyde as needed to convert THP to TKX.
