PYROTEKNISK FORSINKELSESSATS MED BRENNHASTIGHETER FRA 2 TIL 30 MM/SEK

摘要

This invention refers to a pyrotechnical delay charge, i.e. a pyrotechnical charge having a very well defined rate of burning. Similar delay charges are generally used in military fuses of various types. The delay charge according to the invention is distinguished by its components and their proportions relative to each other. Within the framework of the limits stated in the patent claims, the delay charges rate of burning can be varied from approximately 2 to approximately 30 mm/s. Characteristic for this delay charge is primarily that it contains more than 10% by weight tin dioxide (SnO2) which acts as an oxidizer and slag former.
