  • Publication number: 20190032789
    Abstract: A cylinder valve assembly includes an actual on-off control subsystem. An intermediate chamber extends between a probe chamber and proximal chamber of the valve body along a main axis. A control port extends radially of the main axis. A valve pin is received by the intermediate chamber and movable between closed and open positions. A control plug is received by the control port and actuatable between on and off positions. Fluid communication between the proximal and probe chambers through the valve body is enabled when the valve pin is in the open position and the control plug is in the on position. Contrastingly, such fluid communication is prevented if either the valve pin is in the closed position or the control plug is in the off position. The control plug is preferably located in radial alignment along the main axis with at least a portion of the valve pin.

  • Publication number: 20180290941
    Abstract: The present invention utilizes a high-speed intensive mixer in fluidizing type solid phase neutralization reactor to blend solid state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste like formation, extrusion, granulation, drying, and grinding, etc. The new invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, the required plant space, and labor and energy costs. All these factors coupled with increased productivity will drastically lower the overall production cost. Also the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues.
