Patent number: 10683941Abstract: A valve having improved resistance to black powder wear and damage includes a valve body defining a flow passage therethrough, an upper bonnet assembly defining a stem opening, and a stem passing through the stem opening. The valve also includes an elongate gate having a proximal end operatively attached to the stem, a distal end, an orifice sized and adapted to permit essentially unopposed passage of material through the gate when the orifice is aligned with the flow passage of the valve body, the orifice being located proximate the proximate end of the gate, and a solid portion sized and adapted to substantially completely block the flow of material through the gate when the solid portion is aligned with the flow passage of the valve body, the solid portion being located distally of the orifice such that the orifice is located between the proximal end and the solid portion.Type: GrantFiled: July 25, 2018Date of Patent: June 16, 2020Inventors: Ruben F.

Patent number: 10081766Abstract: A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.Type: GrantFiled: June 17, 2016Date of Patent: September 25, 2018Inventors: Ruben F. Lah, Kenneth Krause, Gary Larsen

Patent number: 9486762Abstract: A center feed system allows residual byproduct to be injected into a vessel from within the center of the vessel. The center feed system can include an inlet sleeve that is attached to the vessel and a retractable injection nozzle that extends into the vessel to inject residual byproduct into the vessel and that retracts into the inlet sleeve after injecting the residual byproduct. A retractable injection nozzle may include one or more openings that each includes an insert that can be removed from the opening. The inserts can therefore be replaced to customize the functionality of the nozzle or to replace the inserts when they have become worn.Type: GrantFiled: April 30, 2013Date of Patent: November 8, 2016Assignee: Deltavalve, LLCInventors: Ruben F.

Patent number: 8783177Abstract: A system for oscillating a roller driven by rolling contact with a moving substrate. An oscillating assembly comprises first and second opposed gudgeons rotatably mounted on a shaft, the gudgeons being connected by either a plurality of rods or the roller. An oscillation mechanism comprises a reduction transmission assembly having differently toothed input and output pulleys. A cam groove in an oscillation cam is engaged by one or more oscillation pin(s) connected to the gudgeons. An input drive pulley turns with the gudgeons, and an output pulley turns with the oscillation cam. An intermediate double-pulley has second and third pulleys on a common hub. First and second timing belts connect, respectively, the input pulley to the second hub pulley, and the third hub pulley to the output pulley. A currently preferred step-down ratio between the input pulley and the output pulley is about 391:1.Type: GrantFiled: October 19, 2011Date of Patent: July 22, 2014Inventors: Brian Giardino, Ronald Sweet, James Fischer, Gary Larsen

Patent number: 8702911Abstract: The present invention features a center feed system in combination with a coking vessel of a delayed coking system, or any other similar system. The center feed system features an inlet sleeve which slidably engages a retractable nozzle, with inlet and outlet, in fluid connection with a feed source of residual byproduct, allowing residual byproduct to flow from the feed source into the interior of the vessel, thus effectuating or inducing even thermal distribution throughout the vessel. The retractable nozzle is structured to extend through an opening in the coking vessel while introducing the residual byproduct into the coking vessel and retract out of the coking vessel and cover the opening for at least a portion of a coking cycle.Type: GrantFiled: February 11, 2009Date of Patent: April 22, 2014Assignee: Curtiss-Wright Flow Control CorporationInventors: Ruben F.

Publication number: 20070181734Abstract: A web-chopping and sheet-winding apparatus comprising an unwinder for unwinding a supply roll of continuous flexible web which may be adhesive on at least one side. A knife roller including at least one fixed transverse knife blade extending from the surface is in nipped relationship with an anvil roller, the height of the knife blade being greater than the thickness of the web. The anvil and knife roller spacing is such that the knife blade extends just to the surface of the anvil roller, thereby chopping the continuous web into sheets as the anvil and knife rollers turn synchronously with the web passing therebetween. A tape core roller in nipped relationship receives the chopped sheets sequentially, the leading edge of each sheet being lifted from the anvil roller by any of a plurality of novel means.Type: ApplicationFiled: March 27, 2007Publication date: August 9, 2007Inventors: Frank Corrado, Gary Larsen, Ronald Sweet, James Fischer
