    Abstract: A process for the preparation of ''''Gudol powder'''' from a mixture of nitrocellulose, diglycol dinitrate, nitroguanidine, and additives, wherein an aqueous raw mixture of nitrocellulose and diglycol dinitrate is premixed with the other components, the said final mixture then dehydrated in part, plasticized, and finally pressed into the final shape of the powder product. The improvement in the process comprises reducing the water content of the premixed components in a first drying stage, then homogenizing and preplasticizing the premixed components in a continuously operating masticator, thereafter further reducing the water content of the composition in a second drying stage, thereupon plasticizing and converting the composition into granular form in a continuously operating extruder, adjusting the moisture control of the granulated material to a required pressing or extruding moisture, and finally extruding the granulated material to the final shape of the powder product in a continuously operating extruder.

    Abstract: A rocket motor having at least two coaxial combustion chambers, one arranged behind the other and each containing a solid propellant charge. A partition is positioned between the first and second chamber and between each successively sets or pairs of chambers. This partition has closure means for preventing ignition of the second charge during ignition of the first and for allowing through flow due to excess pressure generated by ignition of the second propellant charge.
