摘要： A multilamp photoflash assembly comprising a housing defining two adjacent regions therein, a plurality of flashlamps within one of said regions having at least one pre-energized striking mechanism associated with each of said lamps, and a rotatable actuating member for sequentially actuating each of the striking mechanisms and thus cause firing of the lamps. In another embodiment, there is disclosed a photoflash assembly wherein a plurality of flashlamps are located within both of said regions and a single actuator is used. In still another embodiment, both regions of the support member are occupied with flashlamps and a pair of rotatable actuators are employed.

摘要： A photoflash lamp having a polycarbonate coating over its glass envelope with an alkali-barrier coating disposed between the glass envelope and polycarbonate coating for extending the shelf-life of the polycarbonate coating by preventing alkali released by the glass from reacting with the polycarbonate. The alkali-barrier coating may be applied to the glass envelope before vacuum-forming a preformed polycarbonate sleeve thereon, or the alkali-barrier may be applied as a thin film on the interior surface of a preformed polycarbonate sleeve before vacuum-forming the sleeve onto the glass envelope.
