Patent number: 10076239Abstract: A medical system generally comprises a camera head, a beam, and a guide sheath. The camera head is connected to the beam which is bendable in a first direction and resists bending in a second direction opposite the first direction. The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath. The guide sheath includes first and second sheath portions, and in an operative configuration the first sheath portion is angled relative to the second sheath portion to define a first bend. The beam is oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam resists bending in the second direction.Type: GrantFiled: April 15, 2016Date of Patent: September 18, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: David Keith Piech, Deepthi Jampala, Vihar C.

Patent number: 5300684Abstract: Disclosed is a process for oxidizing ethane to acetic acid which comprises feeding ethane and a recycle gas to a fluidized bed reaction zone containing fluidized particulate solid oxidation catalyst, feeding a molecular oxygen-containing gas separately from said ethane to said reaction zone so that said molecular oxygen-containing gas first mixes with the major portion of the combustible hydrocarbon feed gases within the fluidized bed, said process including the steps of (1) cooling the gaseous effluent from the reaction zone, (2) separating most of the acetic acid in liquid form from the effluent gases, leaving a gaseous stream containing nearly all of the carbon oxides contained in said effluent, (3) purging a small portion of said gaseous stream and recycling most of said gaseous stream as part of the feed to said reaction zone,wherein said purging serves to prevent build-up of carbon oxides in the reaction zone, and said recycling serves to maintain a high proportion of carbon oxides in said reaction zoneType: GrantFiled: December 9, 1991Date of Patent: April 5, 1994Assignee: The Standard Oil CompanyInventors: Nancy C.
