Patent number: 11946000Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. More specifically the-pyoil is present in said feedstock in an amount of not more than 20% by weight, based on the total weight of the feedstock.Type: GrantFiled: May 22, 2020Date of Patent: April 2, 2024Assignee: Eastman Chemical CompanyInventors: Daryl Bitting, Kenny Randolph Parker, Michael Gary Polasek, David Eugene Slivensky, Xianchun Wu, Jerome Leonard Stavinoha, Jr.

Publication number: 20180170769Abstract: An apparatus and method for treatment of waste water, comprising a tank for receiving a waste water influent via an influent pump and discharging a treated waste water effluent via an effluent pump; a screen decanter disposed in the tank, the screen having a pore size of about 50 micrometers; and a timer operationally connected to the floating decanter and the effluent pump. Solids are settled from the waste water and drawn off through the tank bottom after a supernatant fluid is drawn off through the floating screen decanter. The supernatant fluid may be passed through a filtration and membrane water purification apparatus to generate purified water.Type: ApplicationFiled: February 15, 2018Publication date: June 21, 2018Inventors: Terry Wright, Leonard A. Parker, Robert S. Karz, Jason E. Fox

Patent number: 9511420Abstract: The present invention is a rotary head tool that is a self-propelled rotary tool (SPRT) operable for round cutting involving hard turning. The rotary head tool comprises generally a toolholder, a tool that is removably or fixedly connectable to the toolholder, and an insert that that incorporates a cutting edge finable into the tool. The toolholder is formed to hold the tool with the insert therein at a particular angle. Elements of the rotary head tool of the present invention, such as the insert, may be “off the shelf elements and consequently the present invention may be produced at a low cost. Embodiments of the present invention are designed so that the rotary head tool provides economical benefits and affordability for the user and to provide performance benefits of SPRTs.Type: GrantFiled: June 6, 2012Date of Patent: December 6, 2016Inventors: Grant Leonard Parker, Hossam El Deen Ahmed Kishawy

Publication number: 20160288021Abstract: An apparatus and method for treatment of food process waste water, comprising a tank for receiving a food process waste water influent via an influent pump and discharging a treated food process waste water effluent via an effluent pump; a floating decanter disposed in the tank; a valved outlet formed in the bottom of the tank; an upper level float switch operationally connected to the floating decanter; a lower level float switch operationally connected to the floating decanter and to the effluent pump; and a timer operationally connected to the floating decanter and the effluent pump. Solids are settled from the waste water and drawn off through the tank bottom after a supernatant fluid is drawn off through the floating decanter. The supernatant fluid is passed through a filtration and membrane water purification apparatus to generate purified water.Type: ApplicationFiled: August 13, 2015Publication date: October 6, 2016Inventors: Leonard A.

Publication number: 20150183660Abstract: A waste water treatment system includes a clarification tank having a clarification tank wall. An influent feed system (IFS) is mechanically mounted within and adjacent to a wall of the clarification tank and configured to receive a waste water influent stream including a fluid. A scum trough is mechanically coupled to either the IFS or the clarification tank. The scum trough has a scum trough mouth and a scum trough discharge channel. The scum trough is movable, or a portion of the scum trough includes a moveable structure, to control a rate of fluid in-take of the fluid with scum and floatables from either of the IFS or the clarification tank. Several methods to remove scum and floatables from a waste water stream are also described.Type: ApplicationFiled: August 21, 2014Publication date: July 2, 2015Inventors: Terry Wright, Leonard A.

Patent number: 4980893Abstract: Monolithic high density arrays of independently addressable offset semiconductor laser emitters or elements are able to be placed in close center-to-center proximity, e.g., on 3-10 .mu.m centers, without experiencing any undesirable phase locking and with minimal amount of electrical and thermal interaction or crosstalk occurring between the independently addressed lasing elements and their independent operation in ROS printer applications. With a proper offset in the laser emitters, interlace scanning relative to an image bearing surface, which is required with other multiple emitter lasers in ROS printer applications, is eliminated thereby permitting adjacent line scanning of an image bearing surface without complicated optics and electronics.Type: GrantFiled: February 21, 1990Date of Patent: December 25, 1990Assignee: Xerox CorporationInventors: Robert L. Thornton, Leonard A. Parker
