Patent number: 10024111Abstract: Downhole tools with a topographical pattern, and anti-balling material over the topographical pattern. The topographical pattern may be defined by at least one of a plurality of recesses extending into a surface of a body of the tool and a plurality of protrusions protruding from the surface. Downhole tools include an insert disposed within a recess in a body, and the insert comprises an anti-balling material having a composition selected to reduce accumulation of formation cuttings on the tools when the tools are used to form or service a wellbore. Downhole tools include anti-balling material disposed over a porous mass provided over the surfaces of the tools. Methods of forming downhole tools include providing anti-balling material over features on and/or in a surface of a body of a tool. Methods of repairing downhole tools include removing an insert therefrom and disposing a replacement insert therein.Type: GrantFiled: December 27, 2016Date of Patent: July 17, 2018Assignee: Baker Hughes IncorporatedInventors: Suresh G. Patel, Chaitanya K. Vempati, Steven R. Radford, Timothy K. Marvel, Bruce Stauffer, George I. Butler

Polysulfide generation using a manganese dioxide catalyst assembly and method of making the assembly
Patent number: 7550177Abstract: A catalyst assembly for use in polysulfide generation in white liquor employed in a pulp or paper making process includes a substrate for supporting a catalytic material, at least the surface of which is formed of a corrosion resistant thermoplastic or thermosetting resin, and granular manganese dioxide particles partially embedded in the surface to be mechanically bonded thereto, a catalytically effect percentage of the surface area of the particles being exposed and free of the resin. Also disclosed is a reactor for utilizing such a catalysis assembly and a method of making the catalysis assembly.Type: GrantFiled: November 30, 2004Date of Patent: June 23, 2009Inventors: Paul H.
