  • Remote mine seal spray nozzle assembly, system and methods of use
    Patent number: 7682107
    Abstract: A remote mine seal spray nozzle assembly is provided that includes a rotatable nozzle body attached to a down shaft, multiple string casing. The nozzle body receives interchangeable nozzles coactively seated in a multiport manifold of the nozzle body casing. The nozzle defines a downstream spray outlet that projects a first mix formed of a cementitious grout including a water reducer and a plasticizer. The projected first mix is atomized with a second mix formed of pressurized air and a temperature optimized accelerant. An atomized mine seal mix is thereby created and projected from the downstream spray outlet to form a rapidly hardened mine seal from the accumulated mix projected from the nozzle. The multiport manifold seat establishes an upward directed spray throw axis whereby the projected mine seal mix is projected about a substantially upward arc to optimize the sealing capability of the remote mine seal.

  • Apparatus and method for encapsuling drums containing hazardous wastes
    Patent number: 5443177
    Abstract: Apparatus and method are provided for encapsuling hazardous wastes materials stored in drums. The drum is enclosed in an overcapsule that is grouted to the drum and the contents of the drum are stabilized if necessary with a solidification grout. Once the grouts have set, the overcapsule is positioned onto an undercapsule and grouted to the undercapsule so that the entire capsule with the drum containing hazardous waste inside may safely be transported and stored. The capsule is shaped so that the individual capsules may be stacked one on the other.
