Latest Patents
One of Wolfgang Spranger's latest patents is focused on granulated, stabilized alpha- and beta-octogene. This invention treats alpha-octogene using a new procedure that coats it with synthetic materials, preventing its conversion into beta-octogene at room temperature. The coating process occurs at temperatures between 30°C and 60°C from an aqueous slurry, resulting in granulates that can withstand heating up to 100°C without rearranging into beta-octogene. These granulates are pourable and easily dosable. Additionally, beta-octogene can be coated similarly, particularly when it is in very fine grain form of less than 50 micrometers, exhibiting the same properties as the desired alpha-octogene.
Another significant patent involves a device for igniting a propellant charge. This device features a housing that defines a cavity where a piston is displaceably guided. The cavity connects via a nozzle to a chamber that accommodates the propellant charge. The bottom wall of the case member is equipped with a bore aligned with the nozzle. A primer wafer, thinner in its central zone than in its marginal zone, is placed on the inner surface of the bottom wall. The central zone of the primer wafer experiences mechanical thermal stress during compression, with ignition energy introduced via hot compressed air from the compression chamber.
