Abstract: A flush-mount valve and vent assemblies including the same are described. A flush-mount valve may include a valve mount and a valve barrier which are coupled to the underside of a structure forming part of a liquid-impermeable container. The flush-mount valve is arranged to control the flow of fluid(s) across a fluid passage in the structure and is mounted to the structure so as to remain fully within the interior of the container.

Abstract: A material processing machine for material reducing operations. The material processing machine comprises an infeed system, a reducing system, and a discharge system. The reducing system comprises a rotor having processing tools to reduce the material within a reducing chamber. A colorizer system directs colorant from a colorant source towards the material reducing system within an outlet zone. The colorant colorizes the material being reduced within an inlet zone. The reduced material may be discharged through one or more screens within the outlet zone such that negligible colorant is applied directly to the reduced material. The material reducing operations may comprise a two-stage reducing operation in which the colorizer system is inoperable for the first stage and operable for the second stage. The screens may be selectively interchangeable between stages to incrementally reduce the material to provide substantially uniform colorizing and material size.

Abstract: A personal water craft includes a hull; a deck attached to, or integral with, the hull; a foot well having a foot well floor that is configured to receive a foot of a user of the personal water craft; and a drainage system configured to drain liquid from the foot well, the drainage system having a tube extending from the foot well floor to a location outside the hull.

Abstract: A static bilge pump has a body surrounded by a shell, forming a motive plenum therebetween. Inlets in the front of the shell allow a motive fluid to enter the motive plenum. The motive plenum tapers, decreasing in cross-sectional area along with width as it moves toward its aft, and ends at a motive nozzle. The body houses a suction chamber in fluid communication with a suction inlet that is in fluid communication with the bilge of a boat. Ejectors are positioned proximal to and between the motive nozzle and the discharge outlet. When the static bilge pump is exposed to fluid flow from its front to its stern, such as when a boat is in motion, water enters the motive inlets, filling the motive Plenum and acting as a motive fluid. The motive fluid is ejected at high pressure from the motive nozzle, creating suction at the ejectors and discharging the motive fluid as well as liquid with in the suction chamber out the discharge outlet.

Abstract: A static bilge pump has an inlet tube, a body and one or more eductors. It may be attached to the back of a boat using bolts, or other means such that the inlet tube may be inserted into the drain at the bottom of the bilge of a boat. A siphon tube connected to the inlet tube hasn't ends that may be placed at the bottom of the bilge or moved about by an operator. The eductor's are streamlined to minimize drag and prevent blockage by debris and flotsam. Buttresses may extends between the body and the doctors to improve stability.

Abstract: This invention relates to a device that uses the rocking or pitching motion of a boat caused by wave action to operate a pump in said boat. Said device functions by being so connected as to use the relative motion between said rocking or pitching boat and a submerged plate that resists vertical motion as a means for operating said pump. The function of said pump and its related mechanism is to automatically discharge water overboard from bottom or bilge of said boat.

Abstract: A pumpless bilge water draining system combines a valve system and vented air loop apparatus. The vented air loop is bracketed above the load water line for positive control of the system as well as preventing the system from falling below the water line and endangering the vessel. In motion, a vessel travelling at a sufficient speed will produce a vacuum in the system thus draining accumulated water in the bilge area through the system's pick-up; and at rest, a ball valve is utilized, in an engaged position, to close the valve when it is desired to do so.

Abstract: An automatic boat drain for siphoning water from the interior of a boat, the drain including a flow tube secured to the exterior of the boat transom with the inlet end of the flow tube being below the water surface and oriented so that water is forced to flow through the flow tube as the boat moves forward above a minimum speed, the outlet end of the flow tube being above the water surface, an entraining tube having the inlet end adjacent the interior bottom of the boat, and a venturi forming connection positioned above the water surface connecting the entraining tube outlet end to the flow tube adjacent to and spaced from the flow tube outlet end whereby as the boat moves through water the flow of water forced through the flow tube will produce a venturi effect to drain water from the boat interior while the venturi positioned above the water surface prevents the possibility of water being siphoning into the boat.

Abstract: A water ejector and injector attachment for the motor of a boat comprising a motor adapted to be secured to the frame of the boat carrying a propeller at its lower end and defining a cavitation plate extending rearwardly thereof and having a bore therethrough, at least one recess in the lower surface of the cavitation plate; a trim tab projecting downwardly from the cavitation plate and positioned adjacent rearwardly of the propeller, the trim tab having a passageway therethrough having one end communicating with the bore of the cavitation plate, and a plate member integral therewith and having at least one protrusion upwardly extending therefrom, each of said protrusions mating in the recesses in the cavitation plate; an elongated tube provided through the bore in the cavitation plate with one end secured to and communicating with the passageway of the trim tab and the other end terminating in the bilge of the boat; a spring biasing the trim tab upwardly whereby the protrusions engage the recesses in the cav

Abstract: Boat bailing apparatus for removing water from the interior of a boat comprising: a tubular housing adapted for attachment to the transom of the boat providing a passage through which fluid may pass from the interior of the boat to the exterior thereof; an annular seat near one end of the housing; and a ball closure carried within the housing for movement between a position engaging the seat, preventing fluid flow through the passage, and positions not engaging the seat, permitting fluid flow. A cage assembly may be provided within the housing to confine the ball closure for limited axial movement in the housing passage.
