Publication number: 20240125232Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.Type: ApplicationFiled: July 10, 2023Publication date: April 18, 2024Inventors: Russell P. Smith, Andrew D.

Publication number: 20150141693Abstract: Disclosed are methods for the continuous flow production of acrylic acid and derivatives thereof from an epoxide feedstock. In one embodiment, the method includes the steps of: contacting a process stream comprising ethylene oxide and an organic solvent with a carbonylation catalyst and carbon monoxide to provide a reaction stream containing beta propiolactone; applying the reaction stream containing the beta propiolactone to a nanofiltration membrane to produce a permeate stream containing beta lactone and a retentate stream containing carbonylation catalyst; and treating the permeate stream under conditions to convert the beta propiolactone into an acrylate ester. In some embodiments, the retentate stream is returned to the first step of the process where it is recharged with additional epoxide and passed through the sequence again.Type: ApplicationFiled: July 2, 2013Publication date: May 21, 2015Inventors: Scott D.

Patent number: 8415441Abstract: The invention is a novel family of polyolefins characterized by chain-walking defects of the type that add extra backbone carbons per monomer. These polyolefins display a large decrease in crystallinity relative to polyolefins known in the art. Specifically, the reduction in crystallinity is much greater than for earlier polypropylenes with a matched content of stereo or 1-alkene type defects. The claimed polyolefins can be made by a diimine-based catalyst. The defects in the polyolefin backbone are generated by a chain walking mechanism in which three or more carbons per monomer are added to the polymer backbone instead of two, as in conventional polymerization or copolymerization methods of alpha olefins. The novel polyolefins can be used in applications such as plastic wrapping, thin films, co-extrusion layers or molded parts in the absence of polymer blending or copolymerization. The cost of materials production can be reduced.Type: GrantFiled: October 4, 2012Date of Patent: April 9, 2013Assignees: The Florida State University Research Foundation, Inc., Cornell University Cornell Center for Technology, Enterprise & CommercializationInventors: Rufina Alamo, Geoffrey Coates, Carolina Ruiz-Orta
