A fuel tank assembly includes a shell defining an opening therein, an access panel connectable to the shell and movable between a closed position where the opening is closed and an open position where the opening is open, and a fuel tank disposed in the shell and slidably engaged with the shell. The fuel tank and the opening are dimensioned such that the fuel tank is slidable out of the shell via the opening when the access panel is in the open position. A generator assembly and a method of servicing a fuel tank of a generator are also described.

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.

An unloader for a shipping container includes a supporter having a frame structure and a pallet base supported by the frame structure and configured to receive the pallet and support the shipping container in an elevated position. A gate moving mechanism is supported by the pallet base and configured to engage the moveable gate assembly when the full shipping container is positioned onto the pallet base. A material director has a first end located beneath the pallet base subjacent of the gate moving mechanism. The material director extends downwardly from the pallet base and terminates at a second end opposite the first end. Bulk material is dispensed from the shipping container into the first end and is discharged from the second end of the material director. Shipping containers may be positioned onto and removed from the pallet base without disassembly of the unloader.

Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.

Embodiments of the present disclosure include an apparatus to support a proppant container including a frame to receive and support the proppant container, the frame having a top surface that receives and positions the proppant container above a conveyor to carry proppant disposed thereon away from the proppant container. The apparatus also includes a box guide assembly positioned on the top surface including a corner assembly having two wall segments, and a guide member extending upwardly and positioned adjacent the corner assembly, the guide member including tapered portion of the guide member, the taper having a first width at a top portion of the guide member smaller than a second width at a bottom portion of the guide member. The tapered portion contacts and directs the proppant container to a desired location.

A tank support base and skid apparatus provides a frame having upper and lower end portions, left and right side portions and front and rear portions. The upper end portion has a front row of tank receptive supports and a back row of tank receptive supports. A frame floor is spaced vertically below the tank receptive support. The frame has a peripheral fluid barrier that includes a front wall, a rear wall and side walls that form the fluid barrier around the floor, each side wall extending from the floor to a tank receptive support. First and second internal support members span from one side of the frame to the other side of the frame and each spaced between the front wall and the rear wall. Each tank receptive support includes horizontal beams that span from the front wall to the rear wall and supported by the internal support members vertical members that each connect with a horizontal beam. Inclined plates each connect to both a horizontal beam and a vertical member. Stops mounted on the beams separate a tank receptive support of the first row with a tank receptive support of the back row.

An attachment device comprising a base and a body section extending from the base and comprising two opposing arms. Each arm comprises a displacement limiting section and an interfacing surface. The arms cooperate to define an opening and are configured to be displaced by an object positioned within the opening and interfacing with the interfacing surfaces. Furthermore, the arms are configured to exert a compressive force on the object placed in the opening as a result of the displacement thereof.
