  • Method for agglomerating and passivating used material or fines resulting from the production of organohalosilanes
    Patent number: 7651545
    Abstract: The process for agglomerating and passivating the pulverulent used material and/or the pulverulent fines resulting from the production of organohalosilanes, comprises the mixing of this used material and/or fines with a binder chosen from aluminum silicates and the production of a solid agglomerated product by compression in a press, such as a roll type briquette machine. The invention also relates to the agglomerated product thus obtained and to its use in the recovery of certain metals, such as silicon and copper.

  • Safety device for an apparatus under gas or vapor pressure
    Patent number: 5861126
    Abstract: A safety device for gas or steam pressure vessel, including at least one downstream valve connected to the pressure vessel via a tubing with a burst disc dividing the tube into an upstream section A and a downstream section B. The downstream section B includes a protective assembly for minimizing the maximum pressure of a shock wave generated when the burst disc is broken and strikes the valve.
