Patent number: 9199269Abstract: A substrate coating method may include: translating the substrate in a first direction through a spray zone while spraying a fluid coating on a first uncoated surface portion to produce a first coated surface portion; heating at least the first coated surface portion to form a first cured coating while translating the substrate through the heating zone in the first direction and a second, opposite direction; manipulating a second uncoated surface portion in a position to be spray-coated; spraying the fluid coating onto the second uncoated surface portion while translating the substrate in the first direction through the spray zone to produce a second coated surface portion; and heating at least the second coated surface portion to form a second cured coating while translating the substrate in the first direction through the heating zone. The method may thereby provide the substrate with the first and second cured coatings.Type: GrantFiled: February 14, 2014Date of Patent: December 1, 2015Inventor: Arthur Mark Krawczyk

Patent number: 9079159Abstract: A process for olefin metathesis is disclosed. The process involves contacting a feedstock comprising a first olefin and a second olefin having a carbon number at least two greater than that of the first olefin with a catalyst comprising a tungsten component on a refractory oxide support, e.g. silica at metathesis conditions to provide a product olefin having an intermediate carbon number between that of the first and second olefin. The catalyst is characterized in that it is first pretreated with hydrogen followed by treatment with ethylene.Type: GrantFiled: April 14, 2011Date of Patent: July 14, 2015Assignee: UOP LLCInventors: Christopher P Nicholas, Mark A. Krawczyk, Kristoffer E. Popp, Jennifer F. Abrahamian
