A flooring system that folds up to form a large crate. This crate can be used to hold constructions materials for the building to be built on the floor. The crate is designed to be placed on a foundation. The crate is placed on top of the foundation in the center, perpendicular to beams that make up part of the foundation. Once the base is in place on the beams the crate is unfolded and a flat floor is achieved. All of the pieces of the crate have the flanges that fit onto the beams. They can then be fastened to the beams to secure them in place. The system uses a unique hinge and locking system. At the edges of the sides of each floor panel of the crate are torque tubes that support a cam link and a cam arm that are used to fold and unfold the floor.

A modular, panelized 12-foot wide shelter that has a standard 20-foot length. The shelter has a number of premade frame panels that are assembled over a deck floor. An outer covering of hard, 0.040&#x2033; black ABS sheeting, which can be painted, is applied to the frame. The walls, roof arches, and end panels can be insulated to reduce or eliminate condensation. The floor is insulated as a standard feature. Each wall/roof section has one 5,000 pound rated galvanized anchor ring attached for tie-downs in windy locations, if needed. Because the entire shelter fits on a single pallet, it can be transported to remote sites by various methods&#x2014;trucks, barges, helicopters, or snowmobiles. The shelter can be assembled by two workers in less than a day using simple tools. The structure is designed to be transported by truck, helicopter or snowmobile.

The present invention is directed to using methyl acetate from a vinyl acetate-based or a vinyl- or ethylene-alcohol based polymer or copolymer process directly for use in a methanol carbonylation production process to produce acetic acid, acetic anhydride, or a coproduction of each. Methyl acetate is a by-product of commercial polyvinyl-alcohol or alkene vinyl alcohol copolymer-based processes. Generally, this material is processed to recover methanol and acetic acid. Discussed herein is a cost-saving scheme to by-pass the methyl acetate processing at production or plant facilities and utilize the methyl acetate in an integrated methanol carbonylation unit. The scheme discussed eliminates an expensive hydrolysis step often associated with the polymer process.
