| 64 | Apparatus and method for injecting a liquid dye into a polymer melt | US11040443 | 2005-01-21 | US07278776B2 | 2007-10-09 | Ulrich Helbing; Georg Stausberg; Jörg Alexander; Jürgen Hasenburg |
| An apparatus and a method for injecting a liquid dye into a polymer melt, which includes a metering pump with a metering inlet and a metering outlet. The metering inlet connects to a dye tank and the metering outlet connects to a polymer melt carrying component. To add the liquid dye to the polymer melt in the melt carrying component in a quantity that is as uniform and accurate as possible, the invention provides for connecting the metering inlet of the metering pump to a feed outlet of a feed pump, which connects with its feed inlet to the tank. With that, it is possible to generate a feed pressure at the metering inlet of the metering pump, which can be adapted to an injection pressure at the metering outlet of the metering pump. | ||||||

| 67 | Dual rotor flow meter | US971229 | 1997-11-15 | US5992230A | 1999-11-30 | Thomas J. Scarpa, deceased; Kenneth R. Hoffer; Robert Hayman |
| A positive displacement flow meter includes a pair of smooth oval shaped rotors mounted to a pair of spaced apart rotatable shafts contained within a sealed housing. The rotatable shafts penetrate the measuring chamber and have a pair of toothed, oval shaped timing gears located in a separate gear cavity chamber which are responsible for synchronizing and maintaining the relative orientation of the smooth faced rotors with respect to one another. The fluid that is being metered forms seals between the rotating surfaces of the rotors, as well as between the rotors and the wall of rotor chamber, thus the inlet and outlet plenums are physically isolated and are consequently not in direct communication at any point during the rotation cycle of the rotors. Thus, each rotation of the rotors results in the transport of a precise and known volume of fluid from the inlet plenum to the outlet plenum. A magnetic sensing/counting system, which includes an magnetic actuator attached to one of the rotor shafts and a magnetic sensor mounted to the flow meter housing, monitors the rotation rate of the rotors and hence the flow rate of the fluid passing through the meter. | ||||||
| 68 | Pump and flow sensor combination | US575213 | 1995-12-20 | US5727933A | 1998-03-17 | Michael A. Laskaris; Glenn D. Quinty |
| A pump for use in additive systems such as foam chemical additive systems for fire fighting water, the pump including impeller elements and flow meter elements in a common casing. The pump casing provides a gear pump arrangement using two enmeshed gears on an inlet side, and a closely adjacent gear flow meter arrangement downstream of the gear pump arrangement within the same pump casing. The gear flow meter elements are driven only by the force of liquid pumped by the enmeshed gears of the gear pump and cause very low pressure drop across the flow meter elements. Therefore, inaccurate measurements of flow rates due to slippage and viscosity variation are reduced compared to measuring the rotary speed of gear pump gears directly. The system is optimally used to meter and add foam chemical into a pressurized water line for fighting fires. | ||||||
| 69 | Fluid metering, mixing and composition control system | US235007 | 1994-04-28 | US5423661A | 1995-06-13 | Stephen C. Gabeler; William W. Carson |
| A gear pump is used for the primary flow source for a low pressure, high performance separation system. The pump is controlled such that its flow and leakage characteristics are compensated by an electronic controller which results in controlled output flow rates to a variety of loads. The pump is particularly suited for use in liquid chromatography (LC) systems, especially LC systems which use membrane based separation media. A modification to the gear pump results in an efficient mixer, further enhancing its use in LC systems which involve gradient operational modes. Also disclosed are embodiments which allow the gear pump to be used in high pressure separation systems, e.g., high performance liquid chromatography (HPLC) systems. | ||||||
| 70 | Metered liquid dispensing system | US772764 | 1991-10-07 | US5228594A | 1993-07-20 | David J. Aslin |
| A liquid dispensing system utilizes a microprocessor based electronic control and a positive displacement gear pump to accurately meter predetermined batches of liquid pumped from a supply tank. The gear pump is driven by a reversible motor through a gear reducer, and is operative to pump a predetermined fixed volume of liquid for each revolution or fraction of revolution of the pump drive shaft. A passive magnetic sensor is positioned adjacent the toothed periphery of a target wheel, which is mounted on the motor shaft, and generates a signal representative of the amount of rotation of the pump drive shaft. The electronic control is responsive to this signal for calculating the total volume of liquid dispaced by the pump. The electronic control includes a keyboard which enables a user to preprogram the precise amount of liquid to be dispensed. The system includes a discharge hose for dispensing the liquid into a user's container, which hose is automatically primed by the system prior to the dispensing operation. The system can also be provided with a provision to "drain back" the liquid into the supply tank after the dispensing operation, and/or to recirculate liquid through the supply tank when it is desired to mix the contents thereof. | ||||||
| 71 | Ink metering assembly | US183463 | 1988-04-15 | US4856427A | 1989-08-15 | Charles R. Gasparrini |
| A method and apparatus are described for metering the flow of ink fed under pressure to a printing press. A positive displacement gear meter is interposed in the feed line supplying the ink to the press. The flow of ink through the meter causes rotation of the gears. The rate of rotation is monitored by a sensing device incorporated in the meter housing which generates pulses indicative of gear teeth rotating past the device. The pulses are transmitted to a counter assembly which processes the same and provides a read out of the amount of ink passing through the meter. | ||||||
| 72 | Two-way fluid meter pump | US586684 | 1975-06-13 | US4017208A | 1977-04-12 | Bernard Vonnegut |
| A two-way fluid flow metering pump for accurately measuring the rate of f of a liquid is disclosed. A section of a cylindrical shaft is disposed in a bearing made of metal or a fairly rigid nondeformable plastic. An indentation or notch is made in a shaft section passing an inlet and outlet in the bearing, and liquid is transported by the indentation or notch from the inlet to the outlet, or vice versa, depending upon the direction of shaft rotation. A rubber or soft plastic seal inserted in an opening in the bearing remote from the inlet and outlet deforms and conforms to the shaft indentation at each rotation so that the liquid is not transported past the seal. | ||||||
