Abstract: A headset cover includes a cover body including a stretchable body, wherein the stretchable body is configured to reduce an amount of ambient noise when the stretchable body is placed over at least a portion of the headset, wherein the stretchable body comprises an inner surface and an outer surface, wherein the inner surface defines a body cavity; and a lip, wherein the lip defines a cavity opening, wherein the cavity opening provides access to the body cavity, wherein the lip is configured to secure over at least a portion of the headset. The stretchable material is debris impermeable, fluid impermeable, and disposable.

Abstract: A drain plug for selectively draining a source of fluid is described, and which includes first, second and third portions which provide coaxially aligned fluid passageways which extend therethrough, and wherein the second portion is moveable relative to the first and third portions between a first position which substantially occludes, and prevents the passage of fluid through the coaxial aligned fluid passageways, and a second position where fluid is allowed to pass therethrough and may be collected for disposal as required.

Abstract: Carpet yarn is provided which is significantly less sensitive to changing ambient environmental conditions. As such, the carpet yarns exhibit substantially uniform wet bulk properties across a wide range of ambient temperature and/or atmospheric moisture conditions so as to reduce significantly (if not eliminate entirely) visible streaks in carpets formed of such yarns. In especially preferred embodiments, the carpet yarns when made are subjected to a substantially higher draw ratio and a substantially higher precrimp temperature prior to being brought into contact with water supplied by means of a non-peristaltic, continuous pressure, steady stream pump. The resulting yarn moisture content is increased to a greater level as compared to conventional carpet yarns not possessing the environmental desensitivity exhibited by the yarns of the present invention.

Abstract: A process for cleaning a glass-coating reactor includes: (a) providing the reactor to be cleaned, wherein the reactor contains a glass substrate within a chamber and the chamber has an internal surface coated with at least one substance selected from the group consisting of Si3N4 or SiO2; (b) terminating a flow of a deposition gas to the reactor; (c) adding to the reactor at least one cleaning gas to react with the at least one substance to form at least one volatile product; and (d) removing from the reactor the at least one volatile product.
