Patent number: 11814456Abstract: A method of producing bimodal ethylene-based polymer includes reacting ethylene monomer and C3-C12 ?-olefin comonomer in the presence of a first catalyst in an agitated reactor to produce a first polymer fraction, and outputting effluent from the agitated reactor. A second catalyst is added to the effluent downstream of the agitated reactor and upstream from a non-agitated reactor, the second catalyst facilitates production of a second polymer fraction having a density and melt index (I2) different from the first polymer fraction. The second catalyst and effluent are mixed in at least one mixer. The second catalyst, second polymer fraction, and the first polymer fraction are passed to the non-agitated reactor; and additional ethylene monomer, additional C3-C12 ?-olefin comonomer, and solvent are passed to the non-agitated reactor to produce more second polymer fraction and thereby the bimodal ethylene-based polymer.Type: GrantFiled: June 13, 2019Date of Patent: November 14, 2023Assignee: Dow Global Technologies LLCInventors: Timothy W. Gambrel, Curvel Hypolite, Daniel S. Rynearson, Michael J. Zogg, Jr., Kyle E. Hart, Michael D. Turner, Jorge Rubalcaba, Pradeep Jain, Mehmet Demirors

Publication number: 20220112363Abstract: Embodiments are directed to compositions comprising at least one polyethylene (PE) having a density ranging from 0.850 g/cc to 0.970 g/cc, and a polymer processing aid (PPA) masterbatch comprising a PPA polymer blend, at least one polymeric carrier, and optionally up to 12 wt. % of one or more inorganic materials. The PPA polymer blend comprises from 40 to 60 wt. % of one or more fluoroelastomers, and from 40 to 60 wt. % of polyethylene glycol. The composition further comprises at least one fragrance oil. The composition is defined by the equation: RED (PE?PPA masterbatch)<RED (Fragrance oil?PPA masterbatch), wherein the RED (PE?PPA masterbatch) is the relative energy difference (RED) value for the PE and PPA masterbatch and RED (Fragrance oil?PPA masterbatch) is the RED value for the fragrance oil and PPA masterbatch.Type: ApplicationFiled: January 7, 2020Publication date: April 14, 2022Applicant: Dow Global Technologies LLCInventors: Fawzi G.

Patent number: 4811568Abstract: A sub-cooler for a refrigeration system is located between the condenser and the expansion device for the evaporator. The sub-cooler has a sealed cylindrical housing with a main inlet coupled to the outlet of the condenser. This inlet is connected to a spray bar located along the length of the housing near its top, and spray apertures are distributed along the length of the spray bar to spray the refrigerant into the interior of the sub-cooler housing. The temperature controlled expansion valve supplies a tapped off portion of the refrigerant from the condenser to a distributor located within the housing. Three to six separate cooling coils, having multiple turns, extend from the distributor throughout the interior of the housing. The other ends of the cooling coils are coupled with a collector in the housing, and the outlet from the collector is injected into the main suction line coupled to the inlet of the compressor.Type: GrantFiled: June 24, 1988Date of Patent: March 14, 1989Assignee: RAM Dynamics, Inc.Inventors: Thomas R.
