| 65 | SYSTEM AND METHOD FOR TREATING FLY ASH | US12488446 | 2009-06-19 | US20090258777A1 | 2009-10-15 | Marc-Andre Tardif; Russ K. Majors; Russell L. Hill |
| A method and system for treating fly ash with a treating fluid by evenly dispersing a treating fluid into a flowing stream of fly ash. By dispersing the treating fluid into the fly ash as the fly ash is flowing, the method takes advantage of natural mixing and particle motion that occurs during flow of the bulk solid. The application of treating fluid is advantageously controlled by an automated controller that has inputs and outputs that allow the controller to adjust flow rate of the treating fluid in correspondence with a measured flow rate of the fly ash. | ||||||
| 66 | Viscosity controller for ink pad printers | US10876797 | 2004-06-28 | US07331703B1 | 2008-02-19 | Ronald Hahn; Steve Bullock; Robert W. Heiges |
| A viscosity controller automatically monitoring and controlling the viscosity of ink in a pad printing device on a continuous basis throughout the printing process includes a sealed ink cup having mounted thereon a motor with a paddle extending into the ink cup, a solvent tank in flow communication with the ink cup, and a valve for allowing selective amounts of the solvent to be added to the ink cup from the solvent tank. The viscosity of the ink in the cup creates torque on the paddle that affects the number of encoder pulses that are counted per time period by a motor encoder mounted to the motor, and the encoder pulses are counted and compared to a look up table stored in the microprocessor of the controller to determine if the valve should be opened to add diluting agent to the ink cup so that the ink viscosity can be maintained at a preset or predetermined value. | ||||||

| 72 | Device for automatically controlling the density and viscosity of the abrasive mixture and the quantity of metallic middlings used in the sawing of granite or hard stone | US24610 | 1987-03-11 | US4762422A | 1988-08-09 | Luca Toncelli |
| The device provides for intercepting a determined quantity of the abrasive mixture used in cutting granite or hard stones from conduit (2) which introduces the mixture to the sawing machine by means of valve (3). The mixture then is collected in a dosing hopper (1) where the density and the viscosity are determined. Afterwards the mixture is washed with water and is weighed by means of device (11) so that the quantity of the metallic middlings may be determined. Finally, the discharge valve (4) is opened so that the mixture may be recycled to the conduit (2). | ||||||
| 73 | Pressure control valve for fuel injection pumps | US664890 | 1984-10-25 | US4557287A | 1985-12-10 | Helmut Laufer |
| In a pressure control valve for a fuel injection pump, which includes a piston displaceable in the cylinder by the pressure fluid admitted in the cylinder and against the force of a restoring spring which biases the piston, the piston is closely guided in the cylinder with an annular gap which can be maintained constant. The piston includes one portion which forms the annular gap with the wall of the cylinder and two lateral guide portions closely guided in the cylinder. The annular gap is in communication with the pressure control chamber and the spring chamber formed in the cylinder. A throttle is formed at the discharge of the spring chamber. The amount of fuel flowing through the annular gap builds up a compensation pressure at the throttle to compensate for the influence of temperature fluctuations in the fluid admitted in the pressure control chamber of the cylinder. | ||||||
| 74 | Pressure valve | US175192 | 1980-07-31 | US4354517A | 1982-10-19 | Wilhelm Zirps |
| The valve for a pressure-medium-operated hydraulic arrangement has a housing provided with an inlet and an outlet, a slide piston located downstream of the inlet and seal-tightly movable in an opening of the housing under the action of the pressure medium entering the same so as to subdivide the pressure medium into a first stream flowing directly to the outlet and a second constant stream, a laminar throttle member located downstream of the slide piston and associated with a spring-biased control member wherein the laminar throttle member and the control member are arranged so that the constant stream flows through the laminar throttle member and generates pressure drop which acts upon the control member against its bias, and the control member subdivides the constant stream into two partial streams which flow to the outlet means and one of which is throttled, whereby the pressure drop between the inlet and the outlet is maintained at a constant level and thereby the viscosity of the pressure medium is maintained constant. | ||||||
| 75 | Viscosity regulating apparatus and method | US226742 | 1981-01-21 | US4350285A | 1982-09-21 | Eugene F. Holben |
| Apparatus and method for measuring the viscosity of a fluid by drawing a sample of the fluid through a first flow restrictor (24) and forcing the sample through a second flow restrictor (28) having flow restriction characteristics which are identical to the flow restriction characteristics of the first flow restrictor. The difference in pressures of the sample at the exit of the first flow restrictor and at the entrance to the second flow restrictor provides a measure of the viscosity of the fluid and may be used to vary the temperature of the fluid to control its viscosity. | ||||||
| 76 | Flow control system with density compensation | US969901 | 1978-12-15 | US4199003A | 1980-04-22 | James S. Goldsmith |
| Apparatus for continuously measuring and correcting for fuel density in anircraft engine fuel metering system. Fuel, sampled at the inlet to the engine metering valve, is fed through a flow regulator to a vortex spin chamber in which the fuel is tangentially injected. A magnetic ball carried by the fuel in a race integral with the vortex chamber generates an electrical pulse in an electromagnetic coil at a frequency proportional to the tangential velocity of the fuel. The pulse frequency is compared to a reference frequency and the error signal modulates the regulator to maintain the tangential velocity constant. The radial static differential pressure of the chamber is directly proportional to the fuel density. This signal provides a compensating signal to the fuel metering valve for correcting the mass flow rate of the fuel based on a known true volumetric flow rate. | ||||||
| 77 | Control of the viscosity of fuel oil for burners | US614691 | 1975-09-18 | US3977427A | 1976-08-31 | Robert D. Reed; Harold F. Koons |
| An apparatus for the control of the viscosity of fuel oil supplied to burners, which comprises, in series, pump means for supplying the fuel oil to the burner system under a selected pressure, means for heating the fuel oil output of the pump means, strainer means and control valve means and orifice means of selected length and diameter. A differential pressure cell monitors the pressure drop across the orifice due to the flow of fuel oil under a selected pressure set by the control valve. Any variations in differential pressure will be due to corresponding inverse variations of viscosity. The variations in the output of the differential pressure cell are communicated to a valve means which controls the amount of steam passing into the heating means, thus controlling the temperature of the fuel oil, and therefore its viscosity, to a proper value. | ||||||
| 78 | High precision wide dynamic range viscous loss measuring apparatus | US3762429D | 1972-07-07 | US3762429A | 1973-10-02 | FITZGERALD J; MATUSIK F; OPPLIGER H |
| A viscosity measuring system especially useful to pollution and chemical process control applications. A variable gain amplifier drives a magnetic coil which causes a torsion member to oscillate. The amplitude of the oscillations is sensed by a transducer, and converted to a DC voltage by an amplitude monitoring circuit. The DC voltage, which represents the instantaneous amplitude of mechanical oscillation, is compared to a reference DC voltage which represents the desired amplitude of oscillation. The resulting error signal is utilized to control the gain of the amplifier in such a manner that the amplitude of mechanical oscillation is maintained constant and equal to the desired amplitude. The viscosity of the fluid in which the torsion member is immersed is obtained by providing an output signal which is a measure of the power provided by the amplifier to the magnetic coil in order to maintain the desired constant amplitude of oscillation. Preferably, the output signal is obtained from the voltage developed across a resistor in series with the magnetic coil.
