  • Publication number: 20080047973
    Abstract: A system for mixing beverage components in a predetermined ratio is characterized by a housing having a mixing chamber therein, first and second inlets to the chamber and an outlet from the chamber. A first beverage component is flowed through the first inlet to the mixing chamber and a second beverage component is flowed through the second inlet to the chamber for mixing of the components in the chamber and exit of the mixture from the chamber through the chamber outlet. The pressure of the second beverage component in the second inlet is sensed upstream from the chamber and the flow of at least one of the first and second beverage components to the chamber is controlled in accordance with the sensed pressure to deliver to the mixing chamber a predetermined ratio of the first and second beverage components.

  • Patent number: 7156259
    Abstract: A beverage dispensing system includes separate valves for controlling the flow rate of a diluent and a concentrate. Various concentrates of different viscosities can be used and the selected concentrate is identified. The flow rate of the concentrate is determined based on temperature and pressure and on information related to the identified concentrate. The valves are controlled so that the concentrate and diluent reach target flow rates. The target flow rates satisfy a target ratio of diluent to concentrate. If the actual flow rates cannot reach the target flow rates, then the target flow rates are modified to satisfy the target ratio. The structure of the concentrate valve is designed to accommodate proportional metering of any one of the various concentrates.

  • Patent number: 7066353
    Abstract: An apparatus and method for proportionally injecting a liquid chemical into a fluid stream using a portion of the fluid stream as motive force for a chemical injection pump. The apparatus includes a paired single or double acting reciprocating injection pump and driver with the driver piston(s) having a surface area of three times the surface area of the injection piston(s). The portion of the fluid stream is passed through a prime mover to the pump and then discharged to atmosphere. A fluid product flow meter generates a signal which controls the cycling of the reciprocating pump.

  • Patent number: 6997350
    Abstract: Apparatus for adding liquid fertilizer to a water line of a sprinkler system includes a mechanical injector device powered by a paddle wheel turned by water flowing through the water line. The mechanical injector device includes a plunger that moves back and forth in the plunger chamber. Movement in one direction allows liquid fertilizer from a liquid fertilizer reservoir to flow into the plunger chamber and movement of the plunger in the opposite direction injects the liquid fertilizer from the plunger chamber into the water. The mechanical injector device is coupled to the paddle wheel which causes movement of the plunger in the plunger chamber in at least one direction. Spring bias can cause movement of the plunger in the other direction. The mechanical injector device can be disabled to stop fertilizer injection while still allowing rotation of the paddle wheel.

  • Patent number: 6995024
    Abstract: An apparatus and device for dispensing femtoliter to nanoliter volumes of liquid samples are disclosed. The apparatus includes a liquid-support plate, two electrodes, a substrate, and a control unit. The liquid support plate has a plurality of liquid-support regions, each capable of supporting a liquid meniscus thereon. The first electrode contains a plurality of electrode connections, each operatively connected to one of the liquid support regions, for electrical contact with a meniscus supported in such region. The substrate has a first side confronting the plate and an opposite side, and a plurality of sample-holding regions formed in the first side. The second electrode is disposed adjacent one of the two substrate sides. Thus, a selected volume of the liquid can be ejected from or to one or more of the liquid-support regions to or from one or more of the sample-holding regions.

  • Patent number: 6824012
    Abstract: A dispensing apparatus (10) is capable of robotically dispensing plural component materials such as sealants and adhesives with the same precision as single component products and yet will maintain ratio assurance and integrity for mixing the two materials. First look at the flow rate and if the flow rate is too high, decrease is needed on one of the components. The ratio error is then looked at and the flow rate/pressure differential for the material which is there in excess is decremented. Another level of control is provided in that the ratio error is continually examined and the direction of the ratio error is used for additional control. This provides very precise control of ratio and flow and helps prevent oscillation, hunting and other undesirable characteristics in such a system.

  • Patent number: 6820287
    Abstract: A dispenser is provided for dispensing cleaning chemicals such as toilet bowl cleaners. It has a dosing chamber containing therein a floating shuttle that seals a lower opening in the dosing chamber and floats up there from as an aliquot of chemical is prepared for release during the next cycle. There is also a float controlled external valve head at a lower end of the dispenser for alternately opening and closing a lower opening in the dosing chamber. The level of water in the toilet tank controls the movement of the valve head, and dispensing of the cleaner chemical controls movement of the floating shuttle. A grommet provides a valve seat for both the floating shuttle and valve head.

  • Patent number: 6796459
    Abstract: An automatic fill system for a beverage dispenser includes a sensor system for monitoring the beverage level in the dispenser. The sensors are wired in series with a level control board mounted inside the frame of the beverage dispenser. Sensing points are connected in an electrical circuit for maintaining the proper water to beverage concentrate ratio in the mixing hopper of the beverage dispenser. Resistance in the circuit is monitored so that when the resistance in the circuit reaches a predetermined value, a relay and solenoid open to divert water to the mixing hopper for mixing with the beverage concentrate. Sensors in the hopper shut off the dispenser when the beverage level in the hopper exceeds maximum and minimum levels.

  • Patent number: 6592825
    Abstract: A microvolume liquid handling system includes a microdispenser employing a piezoelectric transducer attached to a glass capillary, a positive displacement pump for priming and aspirating transfer liquid into the microdispenser, controlling the pressure of the liquid system, and washing the microdispenser between liquid transfers, and a pressure sensor to measure the liquid system pressure and produce a corresponding electrical signal. Dispensing of a single sub-nanoliter drop can be detected in real time. As the result of dispensing the liquid in sub-nanoliter droplets, the dispensed volume can be precisely controlled. The dispenser automatically detects the liquid surface of the transfer liquid, automatically aspirate, analyze desired volume of the transfer liquid, dispense the transfer liquid without contacting the destination vessel or its contents, and automatically wash off the transfer liquid from dispensing system after each transfer.
