An offset laminate seam system for storage bins for increasing the capacity of bolts in a seam of a storage bin. The offset laminate seam system for storage bins generally includes three or more panels connected together with two or more vertical rows of end fasteners to form a vertical seam. The interconnection of three or more panels continues to form a ring structure. A plurality of the ring structures are stacked upon one another and attached together with fasteners to form the wall of the storage bin and a roof is attached to the uppermost ring structure.

The subject invention pertains to composite straight wall liquid storage tanks held in persistent compression to provide superior watertightness for the life of the tank, including ACI American Concrete Institute 350 code-compliant liquid-containing composite straight wall structures with an integral full-height galvanized steel shell diaphragm fully encased in continuous shotcrete. The provided tapered composite straight wall can incorporate epoxy-bonded diaphragm sheet joints at the floor, wall, L-shaped corner posts, and T-shaped bisecting wall junction plates to support watertight connections. The external envelope and, optionally, one or more internal or bisecting walls of the structure can be provided in persistent compression by compressive post-tensioning.

Secure storage carts are disclosed herein and capable of being assembled and disassembled on-site without common disadvantages that affect storage carts designed for on-site assembly. Secure storage carts disclosed herein may be assembled to a reduced tolerance, eliminating potential points of failure in the assembled cart, and giving the user a more solid feel to the operation. Methods for assembling storage carts are also disclosed herein and can include adjusting the extension depth of a door panel hinge. Methods disclosed herein also may include applying a preloading force to the cart frame, to reduce tolerances between components of the storage cart once assembled. Kits are also provided herein containing the components required to assemble the cart on-site, in configurations that may be easily transported to and from the job site when disassembled. Kits also may provide for straightforward and secure assembly of the carts.

A coal blockage-proof feeding pipe apparatus for a coal storage Eurosilo includes a central telescopic feeding pipe, a coal blockage-proof feeding pipe, and a feeding pipe mounting base connected. A middle part of a first section of round pipes of the central telescopic feeding pipe is of a conical pipe structure with a smaller upper part and a larger lower part; the first section of round pipes is connected to an upper end of the coal blockage-proof feeding pipe; a dust return plate is arranged inside the coal blockage-proof feeding pipe to guide dust-laden gas, generated at a coal falling point below and ascending along a pipe wall, downward, preventing the dust-laden gas from ascending along a cylinder wall into gaps among round pipe walls of the central 10 telescopic feeding pipe. The coal blockage-proof feeding pipe has an exhaust port to discharge the internal dust-laden gas to the outside.
