An area is set as an interference area, in which a transport vehicle is located in a state in which a portion of the transport vehicle overlaps a door trajectory which is a movement trajectory of a fire protection door. A control portion that controls a subject vehicle, which is a transport vehicle to be controlled, prohibits the whole subject vehicle from entering the interference area if it is determined, based on another-vehicle information, which is information of a traveling state of another vehicle that is different from the subject vehicle, and information regarding the interference area, that the interference area is present between the another vehicle located forward of the subject vehicle and the subject vehicle, and that a stoppable area is not secured between a rear end position of the another vehicle and the fire protection door.

A hydrogen fusible link may include a first link member having a thermally conductive material, and reaction region and a bonding region. A bonding material may be in a solid state at an operating temperature and may have a melting temperature that is greater than the operating temperature. A catalyst material may coat the reaction region and may facilitate an exothermic chemical reaction when exposed to gaseous hydrogen to produce heat, wherein heat produced by the catalyst material is conducted to the bonding region via the body to heat up the bonding material. When the catalyst material is exposed to a concentration of gaseous hydrogen that is at or above an activation concentration the reaction region produces sufficient heat to raise at least some of the bonding material above the melting temperature thereby failing at least some of the bonding material.

A generator enclosure for an engine-generator includes multiple walls defining at least one air path. In one example, a first wall includes an exhaust path for the engine-generator, and a second wall includes an intake path for the engine-generator. The generator enclosure may include at least one air flow frame associated with the exhaust path or the intake path and at least one movable wall supported by the at least one air flow frame, At least one thermal fuse may be coupled to the at least one movable wall and configured to release the at least one movable wall to block the exhaust path or the intake path.

There is described an actuator for a damper comprising an electrical circuit, a cable coupled to the electrical circuit, a lower housing supporting the electrical circuit, and an upper housing coupled to the lower housing. The electrical circuit controls positions of the damper. The cable provides power and control to the electrical circuit. The lower housing includes a first trough and a second trough to provide support for the cable in a first direction. The upper housing includes a first protuberance and a second protuberance to provide support for the cable in a second direction. The first and second protuberances are positioned offset from the first and second troughs of the lower housing.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

Various embodiments include a blocking apparatus comprising: a holding apparatus; a receiving element mounted in the holding apparatus about an axis of rotation, defining a through-opening with a through-axis parallel to the axis of rotation; a wrap spring mechanically prestressed in the holding apparatus, with a winding arranged around the receiving element; and a thermocouple made of a material having a lower melting temperature than the holding apparatus and/or the wrap spring. The thermocouple holds at least one end of the wrap spring with respect to the holding apparatus in the prestressed state in such a way that the receiving element can be freely rotated in both drive directions about the axis of rotation. The receiving element is blocked in one of the two drive directions in the relaxed state of the wrap spring and in the triggered state of a thermal fuse.

A smart duct comprises an inlet, an outlet, a damper positioned between the inlet and the outlet, an electromechanical actuator configured to open and close the damper, and a controller configured to operate the electromechanical actuator and retrieve measurements from the sensor and to receive instructions from a central HVAC controller via a communication channel.
