  • Patent number: 9713816
    Abstract: A paint cartridge includes a housing and a piston slidably disposed within a cavity in the housing to divide the cavity into a paint chamber and a solvent chamber. A valve assembly extends through an aperture in the piston to selectively put the paint chamber in fluid communication with the solvent chamber. A solvent inlet provides solvent to the solvent chamber to move the piston. Movement of the piston discharges paint from the paint chamber through the paint outlet.

  • Patent number: 9533270
    Abstract: A system and method of injecting a chemical into a high pressure process stream without pumps or other active components. The system utilizes the differential pressure created by resistive losses of downstream components within a high pressure process stream. A bypass side stream is taken from an upstream pressure location and returned to the downstream side of the resistive inline process component. The chemical solution vessel is pressurized by the higher side of the pressure differential. The solution then passes through a flow controlling capillary tube exiting on the lower pressure differential side into the bypass stream. The high flow rate chemically diluted bypass stream then returns to the process stream at the lower differential process stream tie-in. The chemical solution is isolated from the process water pressuring the vessel by a movable separating device preventing mixing of the two fluids. The vessel can also be pressurized by gas.

  • Patent number: 9088321
    Abstract: A first resistor group and second resistor group are respectively made up of at least three resistive elements connected in series and are adapted to shift respectively direct-current voltage levels of a first signal and second signal to voltage levels obtained by dividing a direct-current voltage between a power source line and ground line. A common mode choke coil is installed between the power source line and the first and second resistor groups. The common mode choke coil includes a first coil unit adapted to connect the power source line with one end of the first resistor group, and a second coil unit adapted to connect the power source line with one end of the second resistor group and magnetically coupled to the first coil unit. This suppresses propagation of power source noises of the same phase to the resistor groups.

  • Patent number: 8640730
    Abstract: A fluid controller apparatus controls fluid flow, such as a solvent gradient flow, in a chromatography system. An apparatus includes a fluid-gradient controller having a fluid reservoir for containing a pump fluid and a pumping device connected to the fluid reservoir for receiving the pump fluid. The pumping device is in fluid communication with parallel-configured first and second solvent lines. The first and second solvent lines each contain a restrictor element and a solvent reservoir. During operation, the pumping device causes the pump fluid to flow through the first and second solvent lines in relation to their respective restriction devices. The pump fluid displaces solvent within the solvent reservoirs. The displaced solvent is mixed to form a solvent gradient.

  • 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.

  • Publication number: 20040094208
    Abstract: An apparatus for adding fertilizer to water flowing in an underground sprinkler system includes a pressure chamber with a bladder therein which holds liquid fertilizer. Water under line pressure surrounds the bladder in the chamber to pressurize the bladder and fertilizer therein. The pressurized liquid fertilizer flows from the bladder through a valve such as a needle valve which controls flow rate and through a valve such as a butterfly valve which opens to allow fertilizer flow when water flows through the line to which the fertilizer is to be added. With no flow of water, the valve is closed to prevent flow of fertilizer. The lid to the opening to the inside of the bladder used to fill the bladder with fertilizer is arranged to operate two valves. One controls flow of pressurized line water into the chamber to pressurize the bladder in the chamber when the lid is opened and the other opens a drain to depressurize the chamber when the lid is opened to allow fertilizer to be added to the bladder.
