<p>METHOD FOR PREPARING PRIMER FOR PERCUSSION-IGNITABLE FLASH LAMP An efficient method of preparing a coating preparation for use in a single step coating of primer for percussion-ignitable flash lamps, providing a combination of efficiency and safety in handling during manufacture. A production quantity of an aqueous mixture is prepared, containing the fuel, the metallic combustible, and the binder, but without the oxidizer. The production quantity is then divided into at least three fuel containing batches each of which contains less than 40 grams of dry ingredients, An aqueous mixture comprising the oxidizer is prepared and at least a portion of this aqueous mixture comprising the oxidizer is added to the fuel containing batch one of the fractions of the production quantity. In this manner most of the ingredients are prepared in large production quantities but the danger of having serious accidents from accidental reactions involving the large production quantity is avoided. Preferably the oxidizer is sodium chlorate.</p> |
