Individual honeycomb shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Internal hexagonal or square shaped modules are assembled and encased by external hexagonal or square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal hexagonal or square shaped modules drain into external hexagonal or square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.

A motorcycle including a frame to which an internal combustion engine is associated, from which internal combustion engine at least one exhaust pipe of combusted gases departs, the exhaust pipe having an open terminal, the frame mounted on a front wheel and a rear wheel, a control board or unit included, for controlling torque produced by the engine and other parameters such as velocity of the vehicle and spatial position thereof with respect to the road surface. The motorcycle including a system to verify when the front wheel of the motorcycle detaches from the road surface during acceleration. The system includes a choke for partializing the section of the exhaust gases outlet area from the exhaust pipe, during partialization. The partialization obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.

A sulfur pit that mitigates water ingress may include a concrete slab roof that comprises a first concrete slab and a second concrete slab; a polymer sealant disposed on an exterior surface of the concrete slab roof; a refractory layer disposed on an interior surface of the concrete slab roof; and at least one expansion joint located in the gap between the first concrete slab and the second concrete slab. The expansion joint may include a fiber rope disposed in the gap between the first concrete slab and the second concrete slab; a fluoroelastomer caulk located (a) in a first spacing between the fiber rope and the first concrete slab and (b) in a second spacing between the fiber rope and the second concrete slab; and a steel plate spanning the gap between the first concrete slab and the second concrete slab.

A system for supplying dry air to a fuel tank to remove moisture and inhibit contamination includes a dry air supply assembly having an air compressor and an air dryer configured to remove moisture from air supplied by the air compressor to the air dryer, and includes a fluid pump mounted within the fuel tank above a fuel level, with the fluid pump receiving dried air from the air dryer. A suction line extends from the fluid pump and includes an open end disposed at a bottom of the fuel tank. The fluid pump is adapted to receive dried air from the air dryer as a motive force to draw liquid from the bottom of the tank into the opening and up the suction line to the fluid pump, and discharge liquid from the fluid pump above the fuel level within the fuel tank.
