Abstract: Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

Abstract: A missile having a payload mounted on an airframe includes a pair of wave aped springs for separating the payload from the airframe at a predetermined time in the flight envelope. Hinged clamshell-half fairing members in the airframe support the payload during the initial stages of deployment by a rocket motor. At the predetermined time an explosive band separation device is actuated so that the pair of diametrically disposed wave-shaped springs can force the clamshell-half fairing members apart and into the slipstream to disengage the airframe from the payload to assure its intended deployment.
