  • Patent number: 8267108
    Abstract: A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, and a three-way valve that passively arms and dis-arms the system. The precise dispensing of liquid by a calibrated dispensing vessel into the adjacent reservoir is accomplished entirely through the management and arrangement of hydrostatic pressure creating a liquid piston generated by the addition of liquid to the adjacent reservoir and its subsequent application to the liquid in the calibrated vertical column that displaces the calibrated volume of liquid into the reservoir at the same rate that liquid is added to the reservoir.

  • Patent number: 8066151
    Abstract: A measuring fluid dispenser for dispensing fluids in measured quantities has a user input device for generating at least one user input signal. A flow regulator provides a known fluid output flow rate by regulating fluid flow between an input port and an output port of the regulator. A first electronic valve is responsive to electronic signals, wherein a first electronic signal positions the first electronic valve in a flow permissive state, and a second electronic signal positions the first electronic valve in a flow restrictive (i.e. interrupting) state. The first electronic valve has a first valve input in fluid communication with the regulator output and also has a first valve output in fluid communication with a fluid output port. A processing unit is communicable with the user input device and is responsive to the user input signal, and is also in electronic communication with the first electronic valve for transmitting the electronic signals to the first electronic valve.

  • Patent number: 7992490
    Abstract: A by-pass control system for a meat injection system has a variable speed pump that transports fluid to a meat injection machine. Excess fluid is transported to a by-pass control valve. The valve has a moveable piston disposed therein that separates the valve into a fluid chamber and an air chamber. The piston moves back and forth based on the relationship between fluid pressure and air pressure. Sensors are disposed within or through the lid or the valve to sense the position of the piston. A controller is connected to the sensors and the variable speed pump and adjusts the speed of the pump based on the position of the piston.

  • Patent number: 6119896
    Abstract: The command device for dispensing fluids comprises a handgrip posteriorly constrained to a fluid feed pipe and anteriorly bearing a spout connected to the feed pipe and destined to be introduced into an access mouth of a container to be filled with the fluid. A trigger can selectively assume at least a first, closed position in which a connection between the spout and the fluid supply pipe is closed, and a second, open position in which the connection is opened. A mobile lock can on command assume at least a first, locking position, in which the trigger is maintained in the open position, and at least a second unlocked position in which the trigger is free to return into the closed position.

  • Patent number: 4964784
    Abstract: A system for dispensing a liquid, which may be corrosive, in an amount which is substantially fixed for each cycle of operation includes an airtight measuring vessel with an inlet conduit through which liquid is introduced unidirectionally and an outlet or discharge conduit through which the measured amount of liquid is dispensed. The outlet conduit extends to a predetermined level within the vessel and above it is a float/valve mechanism operating in association with an airjet pump. The operation is such that when the float is buoyed to an operative level higher than the predetermined level, conditions are changed within the vessel to commence the dispensing cycle which terminates when the level of liquid falls below the predetermined level whereupon the float/valve drops to an unbuoyed position to commence the next filling cycle. Operation of the jet pump is required during cycling to cooperate with the float/valve mechanism and create the conditions necessary for filling and for dispensing.

  • Patent number: 4630753
    Abstract: A liquid dispensing device for an automatic chemical analyzer or for other chemical apparatus. A dispensing tank is located inside a filling bulb. The dispensing tank has an inlet opening and becomes narrower above the inlet opening to form a vent. The dispensing tank is filled with the dosed liquid by an overpressure from a reservoir which is placed beneath the dispensing tank. The dosed liquid is pushed out from the dispensing tank through a dispensing pipe by regulated overpressure. A regulation tank, a filling bulb, and an isolation pipe isolate the liquid dispensing device from the reservoir and enable the dosing of liquid from a flow channel; or from a large tank, or from a pipe under pressure. A new construction of an air distributor with one nozzle controls the air flow in the liquid dispensing device. The air distributor may control one or more dosing devices.

  • Patent number: 4276999
    Abstract: A beverage dispensing system which lessens confusion and operator time by providing a control switchset with only a small number of selection switches to send encoded signals to an electronic control which decodes the selection data and selects ingredients to be dispensed from more numerous types of ingredients stored remotely. An electronic control regulates the volume dispensed by counting electronic volume related signals sent from each liquid delivery pump shaft as ingredients are dispensed, and stopping that particular delivery pump when a predetermined number of signals have been delivered. Switches are provided to electronically alter the number of counts necessary to stop the delivery pump for one ingredient for one dispensing cycle or for all ingredients for a period of time. The electronic control is capable of storing a first ingredient selection and simultaneously by dispensing a plurality of ingredients upon receiving a second selection.

  • Patent number: 4101055
    Abstract: Disclosed is a machine including a plurality of containers for a variety of paint colorants and a plurality of measuring receptacles, one connected for fluid communication with each of the containers. A cyclic pumping system simultaneously pumps metered volumes of colorant into predetermined measuring receptacles from their associated containers during a withdrawal cycle and then dispenses the metered volumes during a discharge cycle. Adjustment of selector mechanisms associated with each measuring receptacle provides the exact quantities of colorant required to formulate a specific volume of a desired paint color. A cycle timer establishes a uniform time period for each of the sequential withdrawal and dispensing cycles regardless of the colorant quantities being dispensed and a sequence timer can be preset to provide the number of sequential withdrawal and dispensing cycles required to formulate paint volumes that are a given multiple of the specific volume.

  • Patent number: 4078964
    Abstract: A method and apparatus for filling a treatment vessel with a fiber material -- liquid mixture. A conventional feeder rotor, having a number of pockets extending therethrough, has each pocket thereof sequentially filled with chips-liquid mixture in a first position from a pretreatment vessel. A portion of the liquid is withdrawn from the pocket, and the pocket rotates to a second position wherein the chips-liquid mixture in the pocket is discharged into a digester by a liquid flow. The pocket then rotates to a third position wherein the liquid in the pocket is discharged by admitting a gas, such as steam, under pressure into the pocket (and the pocket simultaneously filled with gas), and then to a fourth position wherein the gas is allowed to expand and be transported to a pretreatment vessel while the pocket is filled with cooking liquor, and thereby is ready to begin another cycle.
