Patent number: 11969309Abstract: A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mm3 and an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm3.Type: GrantFiled: June 28, 2021Date of Patent: April 30, 2024Assignee: Solventum Intellectual Properties CompanyInventors: Ta-Hua Yu, Jennifer L.

Patent number: 8673134Abstract: A method for the removal of nitrogen compounds from FCC feed or from catalytically cracked distillates including FCC cycle oils by using formaldehyde to selectively couple organic heterocyclic nitrogen species in the FCC feed or FCC distillate to form higher boiling coupling products out of the boiling range of FCC distillate. Removal of the nitrogenous compounds improves the operation of subsequent hydrodesulfurization steps needed for the distillate fraction to conform to low sulfur standards. The formaldehyde is preferably used in the form of paraformaldehyde. The reaction between the nitrogenous compounds in the cycle oil fraction with the formaldehyde is conveniently carried out in the cycle oil pumparound circuit of the FCC main column.Type: GrantFiled: October 20, 2010Date of Patent: March 18, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Stacey E. Siporin, David Thomas Ferrughelli, Steven S. Lowenthal, Randolph J. Smiley, Alan Roy Katritzky, Bruce R. Cook

Patent number: 8168061Abstract: This invention relates to a process for the selective conversion of vacuum gas oil. The vacuum gas oil is treated in a two step process. The first is thermal conversion and the second is catalytic cracking of the products of thermal conversion. The product slate can be varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step. The combined products from thermal and catalytic cracking are separated in a divided wall fractionator.Type: GrantFiled: July 7, 2009Date of Patent: May 1, 2012Assignee: ExxonMobil Research and Engineering CompanyInventors: Martin L. Gorbaty, Bruce R. Cook, David T. Ferrughelli, Jason B. English, Steven S. Lowenthal

Patent number: 8163168Abstract: The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt %, based on the hydrocarbon feed. The hydrocarbon feed is treated in a two-step process. The first is thermal conversion and the second is catalytic cracking of the products of the thermal conversion. The present invention results in a process for increasing the distillate production from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step.Type: GrantFiled: July 7, 2009Date of Patent: April 24, 2012Assignee: ExxonMobil Research and Engineering CompanyInventors: Martin L.

Patent number: 6387249Abstract: The invention relates to naphtha hydrodesulfurization incorporating either high temperature depressurization or controlled heating for mercaptan removal. More particularly, the invention relates to a naphtha hydrodesulfurization process, wherein the hot naphtha exiting the desulfurization reactor contains mercaptans, most of which are removed without olefin loss, by depressurizing the hot naphtha, thermally treating the hot naphtha, or some combination thereof. The desulfurized naphtha may be cooled and condensed to a liquid, separated from the gaseous H2S, stripped and sent to a mogas pool.Type: GrantFiled: October 10, 2000Date of Patent: May 14, 2002Assignee: ExxonMobil Research and Engineering CompanyInventors: Bruce R.
