Patent number: 11814907Abstract: The present disclosure relates to coupler for connecting a drill pipe to a drill bit as well as methods for manufacturing the same. In particular, the present disclosure describes a coupler which includes a housing including a first connecting portion at a first end for connecting to a drill pipe, a base coupled to the housing and including a second connecting portion at a second end for connecting to a drill bit, and an intermediate component disposed between the base and the housing, wherein the coupler is configured for rotation about an axis during use, with the intermediate component allowing limited relative rotation between the housing and the base about the axis.Type: GrantFiled: November 13, 2020Date of Patent: November 14, 2023Assignee: Ulterra Drilling Technologies, L.P.Inventors: Nathan Andrew Brooks, Jason C. Maw, Matthew Roseman, Thomas A. Damian

Patent number: 11098541Abstract: A PDC drill bit for use in downhole air drilling includes a body with a face for engaging a bottom of a hole being drilled and a gauge for engaging a side of the hole being drilled. The face includes a cone, a nose outward of the cone, a shoulder outward of the nose. The bit further includes channels formed in the face of the bit that extend from within the cone to the gauge. The channels define a plurality of blades separated by the channels. Each of the plurality of blades has a leading edge with PDC cutters mounted thereon. One or more of the channels are defined by two side walls and a bottom wall and has a length, width and depth. The width or depth remains substantially constant from a first point on its length within the cone to a second point within the shoulder.Type: GrantFiled: September 28, 2018Date of Patent: August 24, 2021Assignee: Ulterra Drilling Technologies, L.P.Inventors: Christopher M. Casad, Ben Chrest, Thomas A. Damian, Carl Aron Deen, Kristy Everheart, Kerry Sisson

Publication number: 20210156212Abstract: The present disclosure relates to a friction reduction tool having a housing for connecting the friction reduction tool to a drill string or coiled tubing; a force converter within the housing and having a stator, a helical rotor, and a rotational cavity passageway for conveying drilling fluid between the stator and the helical rotor; and a valve assembly; wherein the helical rotor has a bore which extends through the helical rotor and which defines an alternative passageway for the drilling fluid; and wherein the rotational cavity passageway and the alternative passageway are in fluidic communication with the valve assembly.Type: ApplicationFiled: November 23, 2020Publication date: May 27, 2021Applicant: Ulterra Drilling Technologies, L.P.Inventors: Thomas A. Damian, Jason C. Maw, Matthew B. Roseman

Patent number: 10724323Abstract: A downhole tool for cyclically generating cyclical pressure waves in drilling fluids of sufficient magnitude to vibrate a drill string or coiled tubing to reduce friction between drill string or coiled tubing and a wall of an uncased or cased wellbore. A passageway through which drilling fluid flows through the tool is constricted to increase pressure of the drilling fluid while it continues to flow through the tool. A bypass around the constriction is cyclically opened by a rotary valve to increase the flow area through the tool for the drilling fluid while at the same time an axially shifting valve, shifted by a pair of rotating cams, opens to allow drilling fluid to vent to an annulus formed by the drill string or coiled tubing and a wall of the wellbore.Type: GrantFiled: August 17, 2018Date of Patent: July 28, 2020Assignee: Ulterra Drilling Technologies, L.P.Inventors: Matthew B. Roseman, Christopher M. Casad, Thomas A. Damian, Jason C. Maw

Publication number: 20070172687Abstract: The present invention relates to a process for the production of laminated substrates having a three-dimensionally structured surface, wherein a decorative paper which comprises from 5 to 90% by weight, based on the total fiber content, of fibers of synthetic polymers is impregnated with a crosslinkable aminoplast resin, applied to the substrate and three-dimensionally shaped. Furthermore, the invention relates to aminoplast resin sheets or films, and the use of a modified decorative paper for the production of aminoplast resin sheets or films for 3D lamination.Type: ApplicationFiled: May 21, 2005Publication date: July 26, 2007Applicant: BASF AktiengesellschaftInventors: Marta Martin-Portugues, Gunter Scherr, Thomas Damian, Claus Fueger, Ralph Lunkwitz, Jakob Decher, Albert Sester

Patent number: 6197192Abstract: A filtration apparatus includes an array of filters arranged in parallel about a rotatable assembly 24 for successively backwashing each of the filter elements 19 within the array. The rotatable assembly includes a connector bachwash shoe 26 and a cage having an annular circlip 33 supporting a valve element 31 therein. During normal filtration, water flows up the inlet tube 11, through a respective opening 17 into filtration chamber 13, and then through a respective filter element. The filtrate flows upwardly into plenum 16 and out through outlet 14. In a backwashing mode, the assembly 24 is rotated by a moving means that includes shaft 22 driven by a stepper motor 34 such that the valve element is radially unseated out of the backwash outlet 30. Each filter element is then backwashed in turn as an L-shaped passage 27 of the bachwash shoe is aligned with a respective opening 17 allowing backwash fluid to flow out opening 28a to the backwash outlet.Type: GrantFiled: October 15, 1998Date of Patent: March 6, 2001Assignee: Cross Manufacturing CompanyInventors: William Frederick Smith-Haddon, Thomas Damian Cross, Robert Francis Campbell
