  • Transport of explosives
    Patent number: 12025421
    Abstract: A method of vertically transporting emulsion explosive includes, using a pump, pumping a predetermined volume of emulsion explosive, from an emulsion explosive reservoir, into a vertically extending pipe, wherein pumping is effected airtightly at least between the pump and a downstream end of a volume of emulsion explosive that has been pumped into the vertically extending pipe for at least a part of the travel of emulsion explosive of the predetermined volume of emulsion explosive down the vertical pipe.
    Type: Grant
    Filed: April 20, 2021
    Date of Patent: July 2, 2024
    Assignee: AECI Mining Limited
    Inventors: Ellina Kharatyan, Philliphus Rudolf Kotze

  • Method of manufacturing sub-micron silicon-carbide powder
    Patent number: 7939044
    Abstract: A method of manufacturing a silicon carbide powder with submicron size of powder particles wherein a homogeneous reactant mixture comprising a source of silicone, a source of carbon, and polytetrafluoroethylene is locally preheated in a sealed reaction chamber filled with an inert gas under pressure of 20 atm to 30 atm to a temperature sufficient to initiate an exothermic self-propagating reaction ranges from 650K to 900K. In the aforementioned homogeneous reactant mixture, the carbon source is used in the amount from 63 wt % to 68%, the silicon source is used in the amount of from 20 wt. % to 25 wt. %%, and the activated additive is used in the amount of from 8 wt. % to 15 wt. % per 100% of the entire homogeneous reactant mixture.
