Abstract: The biosafety cabinet has a frame, which defines an enclosed work area and a front access opening, and a work surface along the bottom of the work area. One or more intake openings are positioned along the front access opening adjacent the work surface, a recirculation duct is in fluid flow communication with the intake holes, a supply filter is in fluid flow communication with the recirculation duct, and a supply blower is positioned upstream from the supply filter in fluid flow communication with the recirculation duct. One or more exhaust openings extend along the work surface, wherein at least one exhaust opening is positioned adjacent the front access opening rearward of the intake holes. The exhaust openings are in fluid flow communication with an exhaust duct, an exhaust filter, and an integral exhaust blower.

Abstract: A corrosion-resistant electric cable has a metallic conductor, a polymeric insulating jacket surrounding the metallic conductor, and a corrosion-inhibiting powder comprised of a hydrophobic material disposed between the metallic conductor and the insulating jacket. The corrosion-inhibiting powder may be comprised of a mixture of a hydrophobic fumed silica powder and a hydrophobic polyethylene powder.

Abstract: The cable shielding tape of this invention comprises a metal foil layer and a polymer supporting layer fusibly bonded directly to the aluminum foil layer and serving to structurally reinforce the foil layer. The polymer supporting layer comprises a polymer blend of a polyolefin component and an elastomeric component.

Abstract: Disclosed is a telephone wall mounting adapted to receive a mating plug used in the installation of a wall telephone connected to a telephone transmission line, such mounting comprising: a base plate having a centrally located hole, rectangular in shape, having first and second opposing sidewalls each containing an aligned slot and a third sidewall containing a plurality of parallel grooves adapted to receive a like number of spring contacts; two nail head like studs, each having a shank portion one terminal portion of which is integrally connected to a nail head portion and the other terminal portion being in mechanical connection with and extending above the surface of the base plate, the nail head like portions being positioned parallel to the base plate; a rectangular jack housing including four sidewalls circumscribing the centrally located hole integral with and extending perpendicular from the base plate and terminating above the terminal edges of the nail head like portions of the nail head like studs
