A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A proppant discharge system has a container with an outlet positioned in a bottom thereof and a gate affixed adjacent 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 can be a ten foot ISO container.

What is presented is an interface between a hopper and a dust receptacle of a dust collector system, wherein the hopper has an outlet through which collected dust drops. A slide gate is mounted to the outlet of the hopper and a spout is mounted to the slide gate. A lid is configured to secure to the top of the dust receptacle. The lid has a coupling configured to secure to the spout. A slot comprising a locking feature is located on either the spout or the coupling. A rod corresponding to the slot is mounted to the other of the spout or the coupling than which the slot is located. The lid may be removed from the dust receptacle by lifting the lid to move the rod through the slot and the lid is secured by twisting the coupling relative to the spout to move the rod into the locking feature.

A hopper of a pharmaceutical counter comprises a housing defining an interior sized to hold a plurality of pharmaceuticals. The housing defines an outlet in communication with the interior that is sized and shaped to permit the plurality of pharmaceuticals to move therethrough. The hopper also includes a baffle supported by the housing and disposed in the interior. The baffle is disposed between upper and lower ends of the interior. The baffle is arranged to support a portion of the plurality of pharmaceuticals above the baffle when the plurality of pharmaceuticals is held in the interior of the housing. This relieves the head pressure of the pharmaceuticals at the outlet.

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.

A dome cover assembly for automatically opening and closing a through-opening. The dome cover includes at least one reach-around element on one of a cover and flange. The reach-around element at least partially encloses, in a first rotational position, the other of the cover and the flange on a side facing away from the first element. The other of the cover and flange has a recess and, in the first rotational position, the reach-around element engages behind the recess in a first distanced position of the cover and the flange. The reach-around element does not engage behind the recess in a second closer position of the cover and the flange.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A valve and associated components and methods, and a container including such a valve. The valve may be referred to as a non-rising stem gate valve. The valve includes a gate movable by a drive assembly to open and close the valve. The drive assembly includes a thrust bearing assembly configured to resist damage due to thrust force. The thrust bearing assembly can include a race threaded to a drive shaft of the drive assembly. The race can be pinned to the drive shaft by a roll pin.
