Patent number: 9546327Abstract: A process and catalyst that provides for the upgrading of a high endpoint gas oil feedstock that contains significant concentrations of organic sulfur compound and organic nitrogen compounds. Included among the sulfur compounds are the dimethyl-dibenzothiophenes and derivative thereof. The catalyst of the process is an additive impregnated composition or a derivative thereof that further comprises cobalt and molybdenum. The process provides for the upgrading the high endpoint gas oil feedstock by significantly reducing the difficult to remove thiophene and nitrogen compounds and the process does this with a significantly reduced hydrogen consumption relative to processes using comparative catalysts.Type: GrantFiled: April 9, 2014Date of Patent: January 17, 2017Assignee: Shell Oil CompanyInventors: Lawrence Stephen Kraus, John Anthony Smegal, Karl Marvin Krueger

Patent number: 9404053Abstract: A low-pressure process for hydrodenitrogenation and hydrodesulfurization of a gas oil feedstock. The process uses a multi-bed, stacked-bed reactor system. The first and third beds of the multi-bed, stacked-bed reactor system include catalysts that comprise cobalt and molybdenum supported on alumina. The middle, second bed, includes a catalyst comprising nickel and molybdenum supported on alumina that preferably includes an additive. The stacked bed arrangement with the use of the specific catalysts provides for the low-pressure operation and significantly improved HDN and HDS activity with relatively insignificant differences in hydrogen consumption.Type: GrantFiled: April 9, 2014Date of Patent: August 2, 2016Assignee: Shell Oil CompanyInventors: Lawrence Stephen Kraus, John Anthony Smegal, Karl Marvin Krueger

Patent number: 7166207Abstract: A highly accurate, efficient, and non-mechanical method of removing material from the surface of a golf club head using the principles of electrolysis. The process generally includes positioning at least one electrode in close proximity to a portion of a rear surface of a striking plate, flowing a liquid containing an electrolyte between the rear surface portion and the electrode, and applying a low voltage between the rear surface portion and the electrode. The electrode has an overall negative charge and the golf club head has an overall positive charge, such that a pulsed high-density DC current passes between the electrode and the rear surface portion. This results in negatively charged electrolytes in the liquid attracting positively charged molecules of the rear surface portion, such that the designated amount of material from the rear surface portion is removed by electro-chemical oxidation and carried away by the liquid flow.Type: GrantFiled: November 22, 2002Date of Patent: January 23, 2007Assignee: Taylor Made Golf Company, Inc.Inventors: Bing-Ling Chao, Stephen A.

Patent number: 6904663Abstract: A method of manufacturing a face plate for a golf club head is presented to provide face having substantial thickness variation for enhanced performance. The method includes the steps of providing a rolled sheet of metal material having an initial thickness and forming a blank having a prescribed outer shape from the material. The method also includes machining a second side of the blank such that the resulting face plate has a variable thickness. The machining is such that the plate has a first thickness less than or equal to the initial thickness, a second thickness less than the first thickness and a third thickness less than the second thickness. The machining is performed over a substantial portion of the surface area of the second side. Either a CNC lathe or milling machine may be used; however, for an axisymmetric face thickness a CNC lathe is preferred and for an asymmetric face thickness a CNC end mill is preferred. The club head may be a wood-type or iron, and titanium or steel alloys may be used.Type: GrantFiled: November 4, 2002Date of Patent: June 14, 2005Assignee: Taylor Made Golf Company, Inc.Inventors: Kraig A.

Patent number: 6884179Abstract: An improved golf club is disclosed, in which a desired weight for the club's head is precisely controlled by installing into a hosel cavity a selected hosel plug from a group of such plugs having identical sizes but a range of weights. After the selected hosel plug has been installed, the shaft is inserted into an upper portion of the hosel cavity, above the hosel plug. The plug is configured to have little effect on important club head parameters such as coefficient of restitution and center of gravity, and it also is configured to remain in its installed position even if the club's shaft is removed and replaced. The invention is applicable to golf clubs of all kinds, including metal woods, irons and putters.Type: GrantFiled: June 13, 2001Date of Patent: April 26, 2005Assignee: Taylor Made Golf Company, Inc.Inventors: Joseph H.

Patent number: 6824475Abstract: A golf club head is provided having a substantially increased sweet spot across its club face. A preferred construction includes an annular area on a rear surface having increased thickness surrounding a central region with a balance point of the club face. The central region of the face has a generally reduced thickness that is less than the maximum of the annular area but greater than a minimum thickness at the peripheral area. The face material may be metallic, but in alternative embodiments the effective bending stiffness profiles represented by this annular area may be achieved by appropriate use of composites, for example. Methods for manufacturing a golf club head having a face with the bending stiffness profiles of the present invention include forging and machining techniques as well as laser deposition and inertia welding.Type: GrantFiled: July 3, 2001Date of Patent: November 30, 2004Assignee: Taylor Made Golf Company, Inc.Inventors: Michael Scott Burnett, Benoit Vincent, Todd Beach, Stephen Kraus, Yong Ling, David Anderson

Publication number: 20040099538Abstract: A highly accurate, efficient, and non-mechanical method of removing material from the surface of a golf club head using the principles of electrolysis. The method can be used to make golf club heads from very strong material that are difficult to impossible to mechanically machine and golf club heads with very complex or irregular designs and surfaces. The process generally involves positioning an electrode close to the surface of the golf club head in regions where material of the surface of the golf club is to be removed. A non-conductive template is placed in connection with the surface of specific areas of the golf club head to prevent the removal of the material of the golf club head from those areas. A power supply provides a low-voltage, high-density dc current that is passed between the electrode and the surface of the golf club head in the regions where material is being removed.Type: ApplicationFiled: November 22, 2002Publication date: May 27, 2004Inventors: Bing-Ling Chao, Stephen A.
