摘要： A flame suppression cabinet for printed circuit boards includes intumescent material that expands at an elevated temperature to block ventilation openings in a top panel. Fire suppression plates are positioned between adjacent ones of a plurality of printed circuit boards positioned vertically on a shelf rack in side-by-side spaced-apart parallel relationship to prevent fire from spreading between the circuit boards.

摘要： A sheet separating device for removing an uppermost sheet of an adhesive pad containing a plurality of such sheets includes a housing; a support plate for holding the pad, resiliently biased in an upward direction. A sheet separator mechanism is movable in forward and reward directions, includes a frame, a pick wheel mounted for rotation within the frame, and a knife blade having a closed periphery opening therein defined in part by at least one entry projection, wherein the pick wheel is located ahead of the at least one entry projection of the knife blade in the forward direction such that, in use, the pick wheel lifts an edge of the uppermost sheet extending transverse to the forward direction, and the at least one entry projection of the knife blade then moves between the uppermost sheet and a next underlying sheet as the uppermost sheet passes through the closed periphery opening.
