Abstract: A preformed roof ventilation system comprised of a panel including a middle section and flanged lateral edges. The middle section and flanged lateral edges forming a vent trough. The panel is installed on top of roof framing members prior to the addition of roof sheathing so that the flanged lateral edges can be secured between the roof framing members and the roof sheathing. The panel in combination with the roof sheathing creates a vent channel for channeling air from soffit vents along the underside of the roof sheathing and out of the attic through a ridge vent. The panel may further comprise a baffle flap with a living hinge that is adjustable to any pitched roof. The baffle flap forms a barrier to stop insulation from the attic from getting into the eave space and obstructing the soffit vents. Reinforcing elements and a formed grid pattern may be integrated along the length of the panels to increase the stiffness of each panel.

Abstract: A self-registering roof ventilation system comprised of a panel including flanged lateral edges. At least one flanged lateral edge has a registration tab for registering with an adjacent panel. The panel is installed on top of roof framing members prior to the addition of roof sheathing so that the flanged lateral edges can be secured between the roof framing members and the roof sheathing.

Abstract: Procedure for equilibration of the delivery volumes of a multi-channel metering apparatus with an arrangement of independently controlled dispensing channels 1.1-1.n, delivering individual volumes of dispensing fluid to cavities 3.1.1-3.n.n, where measured values relevant to the individual delivery volumes are measured for the same control value and from which an adjustment value is specified with a tolerance band and the control value is adjusted for dispensing channels 1.1-1.n, the measured values of which lie outside the tolerance band. The invention also applies to an apparatus for implementing the procedure.

Abstract: A method, apparatus, and computer instructions for sending a user's availability information to an instant messaging (IM) partner. A user predefines areas of the user's display and associates these predefined areas, or “hotspots”, with user defined messages. If the user is not available to immediately respond to an incoming message, the user may move the IM dialog window to a “hotspot” in the display. Depending upon the user-defined message associated with the “hotspot”, the IM application generates an automated response indicating the user's availability to respond to the message, and sends the message to the IM partner. The user also may predefine and associate the user's IM status with a “hotspot”. Moving an IM dialog window into a “hotspot” automatically changes the user's status based on the associated “hotspot”. This change is communicated to only the particular IM dialog window partner while other IM partners are unaffected.

Abstract: A method of dispersing flux in molten metal includes providing a source of flux powder and a source of gas. An impeller is disposed on an end of a shaft inside the impeller chamber of a base made of heat resistant material. The base is submerged in the molten metal and includes a molten metal inlet opening into the impeller chamber and a molten metal discharge passageway extending from the impeller chamber to an exterior of the base. Molten metal is drawn through the inlet opening into the impeller chamber by rotation of the impeller in the impeller chamber. The molten metal is moved out of the impeller chamber through the discharge passageway by the rotation of the impeller. A discharge stream of molten metal travels through the discharge passageway into the molten metal exterior to the base. The gas flows from the gas source into a refractory flux conduit. The flux conduit extends from outside the molten metal into fluid communication with the discharge passageway.

Abstract: Excitation of a triad artificial photosynthetic reaction center consisting of a porphyrin (P) convalently linked to a fullerene electron acceptor (C60) and a carotenoid secondary donor (C) leads to the formation of a long-lived C+-P-C60? charge-separated state via photoinduced electron transfer. This reaction occurs in a frozen organic glass down to at least 8 K. At 77 K, charge recombination of C*+-P-C60? occurs on the ?s time scale, and yields solely the carotenoid triplet state. In the presence of a small (20 mT) static magnetic field, the lifetime of the charge-separated state is increased by 50%. This is ascribed to the effect of the magnetic field on interconversion of the singlet and triplet biradicals. At zero field, the initially formed singlet biradical state is in equilibrium with the three triplet biradical sublevels, and all four states have comparable populations. Decay to the carotenoid triplet only occurs from the three triplet sublevels.
