Abstract
Abstract A STRUCTURE TO BE USED WITH CAMERAS FOR MAKING FLASH EXPOSURES. THE STRUCTURE INCLUDES AN ELECTRICALLY NON-CONDUCTIVE SHEET, SUCH AS A SHEET OF CARDBOARD, IN FRONT OF WHICH A PLURALITY OF FLASHBULBS ARE LOCATED ADJACENT TO A SURFACE OF THIS SHEET. A PLURALITY OF CONDUCTORS ARE CARRIED BY THE SHEET AT THIS LATTER SURFACE THEREOF AND ARE ELECTRICALLY CONNECTED TO THE FLASHBULBS, RESPECTIVELY. ALSO, A LIGHT-REFLECTING COATING IS CARRIED BY THIS SURFACE OF THE SHEET BETWEEN THE LATTER AND THE BULBS SO THAT AS THE LATTER BECOME ENERGIZED THE LIGHT THEREFROM WILL BE REFLECTED BY THIS COATING. THE COATING ITSELF IS ELECTRICALLY CONDUCTIVE AND IS CONNECTED ELECTRICALLY WITH THE BULBS TO FORM PART OF THE ELECTRICAL CIRCUITS THERETO.
