Abstract:
A roofing system and article for installation on a roof deck. The roofing article includes a body having an upper portion and an underside. A first channel is defined within the upper portion. The first channel includes an inlet. A second channel is defined intermediate the underside of the body and the roof deck. The second channel is operably connected to the first channel through an orifice, such that the outside air can enter the second channel through the orifice.
Abstract:
A roofing article having a body, a first channel defined within an upper portion of said body having an inlet through which outside air can enter the first channel, and a second channel defined in a lower portion of said body. A sheet separates the second channel from the first channel. The second channel is operably connected to the first channel through an orifice in the sheet such that the outside air can enter the second channel through the orifice.
Abstract:
L'emprisonnement d'air est reduit dans les carcasses de pneus (11), du type formees par enroulement d'une bande elastomere (12, 12A) sur un noyau soluble (13) ou sur un tambour, en perforant la bande (12, 12A) en meme temps qu'elle se deplace depuis une bobine debitrice (19) vers la carcasse (11). Les perforations (47, 47A) sont ensuite eliminees pendant la polymerisation thermique de la carcasse (11). La bande (12, 12A0 peut etre maintenue sous tension pour assurer la penetration des elements perforateurs (48, 48A) et pour s'assurer que les perforations (47, 47A) restent ouvertes au fur et a mesure que la bande (12, 12A) est enroulee autour de la carcasse. La qualite du pneu est amelioree en reduisant les inclusions d'air et le taux de rebut des pneus pendant la fabrication est egalement reduit. En effectuant simultanement l'operation de perforation avec l'enroulement de la bande (12, 12A) sur la carcasse (11), les lenteurs et complications pendant le procede de formation du pneu sont eliminees.
Abstract:
A system for management of a roof having first and second decks covering an unconditioned space in a building and a peak, the system having a first channel extending from proximate a lower end of the first deck towards the peak and a second channel extending from proximate a lower end of the second deck towards the peak. The system further includes a router positioned proximate the peak, the router enabling air flowing to the peak from the first channel to be selectively routed to one of a plurality of directions.
