Patent number: 11266820Abstract: A system includes a platform configured for insertion into a user's nostril and a catheter. The platform includes a board having first and second major surfaces and a support extending from the board. The support includes an aperture therethrough. The catheter includes an inflatable tube and a lumen having first and second ends, the first end connected to the tube and the second end connected to a pressurized fluid source for inflating the tube. The tube is configured for insertion through the aperture. A method includes inserting a platform into a user's nostril, inserting a catheter through an aperture of the platform, and inflating a tube of the catheter. Inflating the tube is accomplished by introducing a pressurized fluid through a lumen of the catheter, to thereby cause the tube to conform to a passage of the user's nasal or pharyngeal region.Type: GrantFiled: January 16, 2018Date of Patent: March 8, 2022Inventor: Robert S. Bridge

Patent number: 8663456Abstract: A hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted intimately with a counter-current steam produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is thermally cracked in a coking drum to produce a coker effluent and coke. The coker effluent is separated into a coker gas and a coker liquid. The coker liquid is reacted with hydrogen in the presence of a catalyst to produce a hydroprocessed product. The hydroprocessed product is separated into a gas product and a liquid product. The liquid product is fed to the vaporization unit.Type: GrantFiled: November 23, 2010Date of Patent: March 4, 2014Assignee: Equistar Chemicals, LPInventors: Robert S. Bridges, Sellamuthu G.
