Abstract: A foam dispenser having a metal housing has a spool valve socket therein. A metal handle extends from the housing. A spool valve is disposable within the spool valve socket. A trigger couplable to the spool valve enables the spool valve to be rotated between open and closed orientations within the housing. The spool valve has internal channels for selectively passing liquids through the spool valve in the open orientation and not in the closed orientation. The spool valve also has a channel for selectively passing a gas through the spool valve in both the open and closed orientations.

Abstract: A foam output device, such as a dispenser, a gun, a turreted cannon, a hose adapter, an aerosol can, or others. The foam output device includes a valve configured to switch between a first mode and a second mode. The valve is configured to simultaneously receive a plurality of compositions and a fluid during the first mode such that the compositions and the fluid are able to react with each other within the valve to form a foam thereby. The valve is configured to prevent the compositions and the fluid from reacting with each other in the valve during the second mode.

Abstract: A reinforced composite structure and a method of making a reinforced composite structure are disclosed herein. The structure and methods disclosed herein include a reinforcing flexible material, a barrier layer, and a foam. The barrier layer can be perforated. The foam can pass through the barrier layer to contact and adhere or bond to the reinforcing flexible material. The structure and methods according to the disclosure are useful, for example, in any structural boat component such as stringers, bulkheads, hull and deck stiffeners, beams, fuel tank supports, structural members, long-span stiffeners, corner stiffeners, hull side-to-bottom strengthening, hatch and swim platform reinforcement, insulated compartments, fish boxes, and applications for flat-bed trailers, truck bodies, buses, recreational vehicles, or other types of vehicles, such as aircrafts.
