Abstract: A switchgear housing assembly includes a first switchgear housing including a cable compartment portion and a circuit breaker portion, a busbar portion, and a second switchgear housing a cable compartment section, a busbar section, and a circuit breaker section. An exhaust duct is arranged between the first and second switchgear housings. The exhaust duct is selectively fluidically exposed to at least one of the cable compartment portion, cable compartment section, the circuit breaker portion, and the circuit breaker section. A floating flap assembly is operatively associated with at least one of the first and second switchgear housings. The floating flap assembly includes a floating flap member. The floating flap member is selectively slideable between a closed position and an open position in response to a pressure rise in one of the cable compartment portion, cable compartment section, circuit breaker portion, and circuit breaker section.

Abstract: A switchgear housing includes a busbar portion having a busbar enclosure. A first circuit breaker portion is coupled to the busbar portion. The first circuit breaker portion includes a first circuit breaker enclosure. A second circuit breaker portion includes a second circuit breaker enclosure. A first pressure relief member is arranged in the busbar portion. The first pressure relief member is configured and disposed to guide gases associated with an arcing event from the busbar portion upward through the busbar portion.

Abstract: The described invention is an unique universal ink jet media. The invention incorporates a unique barrier layer based upon UV or EB curable chemistry which replaces common polyethylene extruded bases. The invention also incorporates multiple ink receptive layers. The first layer is based upon gelatin and/or polyvinyl alcohol (PVOH) chemistries and gives the invention excellent ink drytime. Poor drytime is a common problem which leads to smudging and print defects, especially as ink jet printer speeds increase as technology improves. The high ink absorbency of the invention also makes this media well suited for wide format ink jet printers. The next ink receptive layer(s) are based upon pigmented, cellulose chemistry which reduces the tack of the sheet and gives the sheet good waterfastness. This is important for the end use in that the sheet may be frequently handled and exposed to dampness.

Abstract: This patent describes an ink jet printable heat transfer material with cold release properties. The invention consists of multiple layers of coatings applied to a suitable substrate, typically paper. The first optional layer coating consists typically of a pigmented coating bound together with a synthetic or natural binder and is applied in sufficient quantity to level and densify the surface of a given substrate. The second coating is applied over the first and consists of a silicone coating with a controlled surface energy. The surface energy must be such that the subsequent aqueous coatings can be applied over top with good wetting and adhesion, but low enough for an easy removal from the heat transfer after cooling. A third or wash layer is applied over the silicone release layer. This layer must easily wet and adhere to the silicone release layer so the coating does not come off during subsequent coating passes and during handling by the user.

Abstract: A recording material suitable for ink jet printing, and a method for making the same. The recording material includes a dye-receiving layer, a support layer, and one or more microporous membrane layers. The microporous membrane layer(s) can be interposed between the dye-receiving layer and the support layer, and/or can be disposed on a side of the dye-receiving layer opposing the support layer. The microporous membrane layer preferably has pores with, on average, a pore size in a range of from about 0.01 &mgr;m to about 10 &mgr;m, and more preferably in a range of from about 0.1 &mgr;m to about 1 &mgr;m.
