Abstract: Methods for drafting or transferring water from a water supply to a fire pump in fire service include a strainer, the strainer having a hood member with an open bottom inlet having an inlet aperture, an outlet having an outlet aperture, a suctioning structure extending away from the open bottom inlet of the hood member, and the suctioning structure having a base offset from the open bottom inlet. Method of using the strainer including immersing a strainer in a water supply, fluidly connecting the outlet to a suction side of a pumping apparatus, activating the pumping apparatus, transferring water through the hood member, directing the strainer toward the bottom of the water supply and maintaining the strainer at the bottom of the water supply.

Abstract: A baffling system for vehicle-mounted tanks is disclosed that reduces the concentration of vehicle destabilizing inertial forces of contained liquids caused by vehicle movements during transportation. The baffling system includes circular dish-shaped head baffles antipodally positioned with respect to each other, which attenuate forward and rearward directed liquid surges, and a plurality of longitudinal baffles that attenuate side-to-side liquid surges. The circular-shaped head baffles include removable cutouts for access to the tank compartments.

Abstract: An apparatus, a system and a method for obtaining sieved water, for fighting fires, from a source of water having foreign objects are disclosed. A strainer is connected to a tank via a hose such that water may be pumped from the strainer to the tank. The strainer includes a water inlet having a sieve-like material over it and a water outlet connector where the hose connects. The strainer is submerged in a source of water such as a pond or stream. As water enters the strainer via the water inlet, the sieve-like material prevents foreign objects such as rocks and leaves from entering the strainer. Therefore, the foreign objects never reach the tank. A pan may be connected to the bottom of the strainer to elevate the strainer above the bottom of the source of water. Such elevating helps achieve desired flow rates without stirring or roiling foreign objects such as sand or gravel that may be at the bottom of the source of water.

Abstract: A concealed vent system is disclosed for closed system fire tank trucks, which permits the tank truck to be adequately vented while being filled completely by an auxilliary source of water. The vent system is a sloped conduit that originates in the clean out hatch atop the tank and terminates in a valving means external to the tank and rearward of the rearmost wheels of the tank truck, such that water vented does not pose a safety hazard to fire fighters.

Abstract: Angular baffles for vehicle mounted tanks are disclosed which reduce the concentration of vehicle destabilizing inertial forces of contained liquids, generated by movements encountered during transportation. The baffles include symmetrical, hollow internal baffles antipodally positioned with respect to each other, which produce attenuation of such forces by redirecting them through deflection off the angular surface of the baffles into balancing force components, and by otherwise dampening liquid surges.
