A collapsible metal box, in particular for transporting a material sensitive to creep, is provided. The box includes a base and two first and two second opposing side panels hinged to the base. At least one of the first side panels includes a retaining structure for maintaining the same in an upright position on the base while the second side panels are collapsed fully outwards.

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.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

The disclosure provides a method that includes providing or assembling a rectangular horizontal member, joining a vertical member to the rectangular horizontal member such that the vertical member bisects a length of the horizontal member and forms a T-junction at the horizontal member, joining first and second sloped members to the rectangular horizontal member and vertical member such that the first and second sloped members span from a top of the vertical member to opposing ends of the horizontal member, and joining first and second support members such that the first and second support members span from the T-junction between the vertical member and horizontal member to work points on an underside of each of the first and second sloped members. The structure thus formed can be assembled from prefabricated units shipped together in parallel planar orientation in a shipping container to provide a roof truss unit.
