Abstract: A liquid fuel dispensing system with improved means of preventing water and particulate contamination employing an underground fuel storage tank, a pump for moving fuel from the fuel storage tank to a pump fuel outlet, an underground enclosed sump in which at least a portion of the pump is located, a filtration vessel within the sump having a fuel inlet connected to the pump fuel outlet and a fuel outlet, a filter element in the filtration vessel in series with fuel flow therethrough, the filter element having a filter media which intercepts particulate contaminants and which absorbs water to thereby prevent particulate and water contaminants from passing therethrough, a fuel shut-off device in conjunction with the filter element which is moved to the closed position when a predetermined pressure differential develops across the filter media as water is absorbed, the shut-off device serving to, upon actuation, completely block the flow of fuel through the filter element.

Abstract: A dump truck has a tiltable dump body with a tailgate at its rear end. A partition or weir mounted in the dump body and of lesser height than the walls of the dump body divides the dump body into front and rear compartments. A siphon is connected between the two compartments and extends over the partition. The rear compartment, having a discharge opening at its rear end which is closed by a tailgate, receives dredged material in the form of a mixture of water and sand (or silt) pumped thereinto through a supply conduit on the dump body. As the rear compartment is being filled with dredged material, gravity causes the sand (silt) to settle at the bottom and the water to rise to the top and spill over the partition into the front compartment. Some water also flows through the sipon into the front compartment.

Abstract: A device for separating liquids from solids and solids from solids is provided by utilizing a tall column filled with liquid which is subjected to a siphon action that pulls the liquid/solids mixture vertically through the column clarifying the liquid and classifying the solids. This siphon method provides a most efficient method of classification of solids and clarification of liquids. Atmospheric pressure and gravity create forces within the device which simultaneously act on every particle. The interior of the tall column has no moving parts.

Abstract: A flow control valve includes a hollow cylinder 32 having an open end and a fluid flow port 31 formed in its circumferential wall, a solenoid coil disposed around the cylinder, and a valve member 41 slidable within the cylinder in response to an amount of power supplied to the solenoid coil for adjusting an opening area of the fluid flow port to control the flow rate of the fluid flowing through the fluid flow port and the open end of the cylinder. A protective inner-diameter portion 32a formed in the open end of the cylinder is provided in association with a fluid flow path including the fluid flow port and the open end of the cylinder for preventing any foreign matters entrained in a fluid from being caught in the clearance defined between the hollow cylinder and the valve member by providing an annular clearance between the cylinder and the valve member.

Abstract: A piston type valve including a valve body having a horizontally disposed fluid flow passageway with an inlet at one end of the passageway and an outlet at the other end of the passageway. A valve piston is mounted in the body for selective vertical movement to and away from the passageway inlet and outlet to selectively close and open the passageway and control fluid flow therethrough. A debris holding tank is disposed on the valve body below the fluid flow passageway and is in fluid flow communication therewith. The passageway outlet has its bottom portion disposed higher than the bottom portion of the inlet whereby debris contained in the fluid flow through the passageway strikes the outlet bottom portion and falls into the tank. The valve piston is cylindrical and is mounted on vertical guide rods to guide the piston in its vertical movement and to prevent it from turning in a horizontal plane.

Abstract: The instant invention provides a method and apparatus for the verification and calibration of pumping rates in systems having a volumetric pump drawing fluid from a tank. An effluent valve is connected to the base of the tank and in turn the valve is connected to the base of a calibrated column. The column is also connected at its top to the top of the tank thereby providing equalized pressure conditions within the column and the tank. A sight level gauge mounted on the calibrated column, or a transparent calibrated column alone, may be used to determine the liquid level. The liquid levels in both the calibrated column and tank are continually at equilibrium during normal pumping operations. In order to operate the invention, the effluent valve is closed and the decrease in the level of the fluid in the calibrated column is measured during a timed interval to determine the pumping rate.

Abstract: A governor is disclosed in which dust which may comprise steel powder, fine particles of sand and so on will be removed from a hydraulic working fluid by subjecting the working fluid to centrifugal force. A fluid passage for the working fluid is formed in a housing of the governor and a chamber communicates with the passage at the opening. The fluid passage has an opening located such that dust contained in working fluid will enter into the chamber through the opening while the housing is rotating. Within the chamber working fluid will be stagnant and dust sedimented.

Abstract: A pressure control valve assembly comprising a rubber diaphragm to which is applied the negative pressure of the engine intake manifold and the exhaust gas pressure of the engine exhaust manifold. The diaphragm of the present invention is formed with a gradual descent sloping down from a valve-actuating central portion to an outer periphery. Adjacent to one portion of the outer periphery of the diaphragm a port opening to the outside of the valve assembly is provided. Thus, any gas ingredients such as condensed water can be expelled along the descent of the diaphragm via the port without gathering on the diaphragm surface which will therefore be free from objectionable oxidation or corrosion.

Abstract: A cylindrical vessel of large size and integral molded construction is provided having a depressed well which accumulates sludge formed in the course of storage of hydrocarbon fuels. A hole positioned in the top of the vessel directly above said well permits insertion of a pipe which, by suction means, removed the accumulated sludge. Pedestal means, positioned below the tank and adjacent each end, causes the entire vessel to be tilted downwardly toward the well, thereby causing gravimetric migration of sludge toward the well.

A drain tube extending through the bottom cover of the valve body and the bottom wall of the reducing chamber connects the lower end of the sleeve valve to the bottom wall to prevent the vibration of the valve.

Abstract: A throttle control that provides accurate and reliable control for a plurty of remote air driven devices. The throttle control employs a plurality of primary valves that are built into a common body with a handle and a plurality of operating levers. The body has a single air supply port which directs air through a common chamber to all of the primary valves. In the body are formed a plurality of separate chambers that communicate the outlet air from the plurality of respective primary valves to the plurality of air conduits to supply air to the respective air driven devices. The handle has a chamber through which exhaust air has a tortious flow path to atmosphere. Each primary valve employs an air control valve and an air vent valve that are sequentially actuated by the associated operating lever. When the lever is not depressed, the control valve is closed and the vent valve is open and vents the air in the supply conduit through the handle chamber to atmosphere.
