Abstract: A system is described for stabilizing an array of flexible bulk containers that contain a dry flowable material in powder, flake or granular form. An upper section of at least one container includes a releasable connector for detachably coupling the container to an upper section of an adjacent container in the array. The connector serves to keep sidewall portions of the containers in an upright configuration in order to reduce the risk that one or more containers may topple over.

Abstract: Cargo is covered by use of a tarp and a frame that extends over the tarp. A number of cords are connected to the tarp and a plurality of couplers interconnect the cords to the frame. The couplers releasably connect the tarp to the frame so that the tarp can be dropped onto the cargo once the frame is moved into a position over the cargo by, for example, a forklift. Preferably, the cords include free terminal end sections that can be pulled from ground level to disconnect the cords from the frame when desired, so that walking across the cargo can be avoided.

Abstract: A pressure vessel safety relief includes one or more recesses on a bottom wall section of the vessel. The thickness of the bottom wall section in areas directly over each recess is less than the thickness of remaining areas of the bottom wall section. Once the bottom wall section has corroded to a significant degree, the wall section ruptures in areas over the recesses to safely relieve pressure within the vessel. Preferably, the recess decreases in cross-sectional area as the top of the recess is approached, such that the escaping air emits a high-pitched whistling noise that functions as an alarm to notify the user that the vessel is corroded and should be replaced.
