Abstract: The invention relates to plenum rated data communication cables, in particular to a shielded, plenum rated data communication cable for transmitting high-frequency signals featuring a fluoropolymer insulation and metallic shielding, to an unshielded plenum rated data communication cable for transmitting high-frequency signals, to a shielded, plenum rated data communication cable for transmitting low-frequency signals and to an unshielded, plenum rated data communication cable for transmitting low-frequency signals. The fluoropolymer used as an insulating layer enables high-frequency signals to be transmitted with a low signal attenuation. In the case of the shielded, plenum rated data communication cable which is especially adapted for transmitting low-frequency signals, the insulation material used is an ethylenechlorotrifluoroethylene polymer (ECTFE). Where the cables are unshielded, a second jacket layer comprising a polyvinylidene fluorine (PVDF) material is used. PVDF has an effect on the signal attenuation similar to a metallic shield.

Abstract: A modular seal assembly for sealing a circular opening through a wall, usually with one or more conduits (i.e., telecommunication cables) extending through the seal. The assembly includes an outer pressure annulus and a thick inner pressure disc, both of natural or synthetic rubber, EPDM, urethane, or other elastomer. In the outer annulus the elastomer is an annular series of interconnected blocks of length (L1) having a central opening of radius (R2); a series of pressure bolts compress the blocks axially, expanding the annulus both outwardly and inwardly. The inner disc, which has an outer radius of about (R2) and is interlocked with the elastomer blocks of the outer annulus, has a multiplicity of circular layers, much like an onion; the layers are concentric about an opening through which a conduit usually extends. Tightening the pressure bolts causes the outer annulus to compress the disc, forcing the disc against the conduit to complete a seal; the elastomer blocks of the outer annulus seal against the wall opening.

Abstract: An improved forming section of the twin wire type for a papermaking machine is described which increases the fibre content of the formed web of paper while reducing the use of energy intensive vacuum dewatering aids relative to prior apparatus. Stock is injected from the headbox of the machine onto a forming wire which is brought into gradual engagement with a second forming wire. The two wires are directed by a forming shoe along a path of increasing curvature, above which water is drained by adjustable auto slices. The two wires with the web therebetween then follow an oscillating S-path between seven S-rolls and are directed upwardly through three individually loaded press rolls with increasing pressure to about four hundred and fifty pounds per linear inch at the last wet press, the press rolls being individually pneumatically pivotable to increase nip pressure and collectively pivotable to open all the nips. Using a high pressure dry nip, the fibre content of the web can be increased to thirty-five percent fibre. Through improved water removal capabilities of the forming and pressing sections the head of the drying section in the papermaking machine, significant cost advantages are realized.
