A handheld sprayer (10) includes a fluid module (12) mounted to a drive module (14) at a static connection (16) and a dynamic connection (18). The static connection (16) supportably attached the fluid module (12) to the drive module (14). The dynamic connection (18) connects a drive (84) of the drive module (14) to a pump (24) of the fluid module (12) such that the drive (84) can power the pump (24) by the dynamic connection (18). The fluid contacting components of the handheld sprayer (10) are in the fluid module (12). The fluid module (12) can be mounted to and dismounted from the drive module (14) by a sliding motion.

A steam sprayer for delivering steam onto and beneath a field surface is provided. The steam sprayer comprises a support frame having a plurality of steam spraying nozzles mounted thereto and oriented substantially downwardly for spraying steam onto and beneath the field surface. At least a steam generator is connected to the steam spraying nozzles for providing steam thereto. A water heating tank is connected to each of the at least a steam generator for providing heated water at a substantially constant pressure thereto. Compressed air is provided to the water heating tank for pressurizing the water heating tank. Power is provided to the water heating tank and each of the at least a steam generator.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders and/or a directional control assembly to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, balancing feet, a removable nozzle, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.Attac

A paving machine includes a machine frame, a drive assembly, including at least two tracks, each driven by a drive wheel and one or more idlers, and a paving material delivery assembly including a hopper, a conveyor assembly, an auger, and a screed. The paving machine also includes a tank of emulsion fluid, a spray bar positioned on an underside of the machine frame between the at least two tracks and fluidly coupled to the tank to deliver the emulsion fluid to a ground surface.

A coating system for applying a coating to a substrate that can be part of a wall assembly. The system includes a positioning stage and an end effector coupled at a distal end of the positioning stage, the end effector configured to apply coating to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the end effector and positioning stage to perform at least one coating task that includes applying coating, via the coating the end effector, to one or more substrate pieces, the generating based at least in part on obtained target surface data; and drives the end effector and positioning stage to perform the at least one coating task.

A paint sprayer attachment that prevents over spray mist from dispersing into the open air, thus allowing a user to operate a paint sprayer without wearing a mask, includes a spray hood, a first edger, a second edger, a first roller assembly, and a second roller assembly. The spray hood is a thin-walled, dome-like structure to which the first edger, the second edger, the first roller assembly, and the second roller assembly are attached. The first edger and the second edger enclose the sides of the spray hood, and provide non-abrasive surfaces for applying paint to a desired surface. A first paint roller from the first roller assembly and a second paint roller from the second roller assembly are positioned at opposite ends of the spray hood, wherein the first paint roller and the second paint roller enclose the front and back of the spray hood.
