Title:
METHOD AND APPARATUS FOR FLOW IN FLUID
Document Type and Number:
Japanese Patent JPS61191586
Kind Code:
A
Abstract:
The invention relates to a process for realizing the running-in of a fluid comprising at least an explosible component sensitive to shocks and/or rubbing. The process of the invention consists in filling the moulds 2 with a specified quantity of casting powder P, in running-in a casting solvent S into the moulds 2 placed under reduced pressure, and in then curing the blocks thus cast to gel the casting powder. The running-in of the casting solvent S into the mould 2 from the storage tank 3, and the beginning and the end of this running-in of the casting solvent are controlled by controlling the pressure difference existing between the pressure prevailing in the storage tank and that prevailing in the mould 2. Thus, it is possible to control the running-in of the casting solvent into the moulds remotely. The present invention applies especially in the industry for the manufacture of solid propellant compositions.
