    摘要: A seal device is provided in each comparted entrance and exit of a furnace for continuous thermal treatment of a metallic strip using a flammable atmospheric gas. The seal device is provided with seal members for sandwiching the metallic strip to seal the flammable atmospheric gas, seal hardwares each being fixed to a furnace body and pressed by the seal member, and seal mechanisms for sealing the flammable atmospheric gas from the seal member at an urgent time. A differential distribution detector having heat-receiving portions formed of a metallic pipe filled with air is placed over the whole width outside the seal member. When a leaked atmospheric gas is ignited outside the seal member, a rapid temperature increase in the heat-receiving portions is detected to give a signal, whereby running of the metallic strip is stopped, and the seal mechanism is operated to shut off the seal device from the inside of the furnace body. Then, a nitrogen gas is fed into the seal device.

    摘要: A roof vent damper for closing a roof mounted ventilator in the event of a fire includes a frame formed from an elongated rectangular plate having a central dumbbell shaped cut-out. Longitudinal side edges of the plate are folded over to form parallel guide track members. The plate is then folded along a central transverse line extending across a narrow central portion of the cut-out to form overlying plate members separated by a hollow guide track. A damper plate is received for reciprocal sliding movement in the guide track and is retained in an open position by a fusible link which separates at a predetermined elevated temperature. The damper is biased to a closed position by a coil spring.

    摘要: Apparatus for closing off and insulating a plastic article such as a pipe section extending through a fire-resistant wall or floor to prevent the spread of fire by the progressive burning of the pipe section. The apparatus generally includes a slidably movable gate, preferably metal, which seals the walls of the plastic pipe section to interrupt it when it softens in the presence of fire and before it ignites, and baffle or screen the pipe section, thereby insuring against the spread of fire via the pipe section, such as from the hot side to the cold side of the fire-resistant wall or floor. Such apparatus may be installed on either or both sides of the wall or floor through which the plastic pipe section passes.
