摘要： A fire suppression and control system for a commercial cooking unit having a conventional chemical fire retardant discharge system has a flexible fire curtain supported by a hood and adapted to enclose the cooking unit from the room between the hood and the floor. A housing for storing the curtain in folded condition is positioned on the hood and includes a release mechanism for releasing the curtain from the housing when a fire occurs. A heat-responsive control for discharge of the fire-resistant chemical is coupled to the release mechanism for the curtain to release the curtain at the time the fire-retardant chemical is delivered to the cooking unit. The fire-retardant chemical is preferably a Halon 1211 gas. The release mechanism includes an electromagnetic coupling which is connected through an electrical circuit to a switch at a mechanical actuator for the valve in the chemical fire-retardant delivery system.

摘要： A connection arrangement for connecting precast elements. The arrangement including a first member and a second member each for partial embedding in first and second precast elements respectively. The first and second members are connectable together to connect the first and second precast elements. The first member has a portion for embedding in the first element, while the second member has a first portion for embedding in the second element. The first portion of each of the first and second members extend to respective second portions and the second portions of each of the first and second members are arranged for mating connection.
