Patent number: 10974188Abstract: Filters and filter assemblies including one or more shield elements to protect the filter media of the filters during installation of the filters into a filter housing of the filter assembly are provided. A filter includes first and second media packs, a housing seal system, a handle and a shield element. Filter media packs extend from a first end to a second end in a diverging manner. The first end has a length dimension and a width dimension that extend transversely. A shield element projects over the first and second media packs at the first end a span in the width direction of at least 40% of the width dimension defined by the first and second media packs and projecting a span in the length direction of at least 5% of the length dimension defined by the first end.Type: GrantFiled: June 20, 2019Date of Patent: April 13, 2021Assignee: Baldwin Filters, Inc.Inventors: Levi William Dexter, Benny Mathew Varghese

Patent number: 10870074Abstract: A filter element and multi-component holding assembly for a filter element is provided. The filter element includes first and second media panels, a support frame, a base frame and first and second end cap structures. Each filter media panel defines first, second, third and fourth sides. The first and second sides extend between the third and fourth sides. The support frame maintains the first and second filter media panels in a spaced orientation forming a cavity therebetween. The base frame defines a first opening in fluid communication with the cavity. The first end cap structure seals the third side of the first and second filter media panels and the second end cap structure seals the fourth side of the first and second filter media panels. The base frame has a first portion captured in the first end cap structure and a second portion captured in the second end cap structure.Type: GrantFiled: July 15, 2016Date of Patent: December 22, 2020Assignee: Baldwin Filters, Inc.Inventors: Benny Mathew Varghese, Levi William Dexter

Patent number: 6084196Abstract: A nickel-base superalloy article which is susceptible to strain-age cracking and has a directionally oriented, single crystal, or equiaxed grain structure is repaired with minimal welding heat input into the article. The article is first heated to a welding temperature of from about 1650.degree. F. to about 2000.degree. F. in an inert atmosphere. A damaged area of the article is weld repaired using a plasma-transferred arc welder which vaporizes a filler metal in a plasma arc and deposited the vaporized metal onto the article to form a weld overlay. Minimal additional heat is added to the article during welding, as the weldment metal is vaporized remotely from the article.Type: GrantFiled: February 25, 1998Date of Patent: July 4, 2000Assignee: General Electric CompanyInventors: Gilbert E. Flowers, Earl L. Kelly, Jr., Warren D. Grossklaus, Jr., James D. Barber, Gray W. Grubbs, Levi Williams

Patent number: 5466905Abstract: Direct electric current arc welding between an electrode and a workpiece surface is accomplished in the electric current range of about 0.5-45 amps while reversing the polarities between the electrode and the workpiece surface at a low frequency rate in the range of about 1-1000 cycles per second, in a series of polarity cycles. The workpiece surface, in at least some of the cycles, is positive for a time less than that surface is negative to result in anodic cleaning of the workpiece surface. If the arc is extinguished during a polarity reversal, the arc is maintained, for example, by restriking.Type: GrantFiled: April 5, 1994Date of Patent: November 14, 1995Assignee: General Electric CompanyInventors: Gilbert E. Flowers, Joel H. Cohen, Earl L. Kelly, Jr., Levi Williams, Gray W. Grubbs

Patent number: 5464958Abstract: A variable polarity device reverses the polarity of an electrically conductive workpiece and an electrode, having opposite polarities, between positive and negative in a low D.C. range of about 0.5-45 amps. Combined with the device is a control means which schedules a frequency of time rate of the reversing in the low time frequency of about 1-1000 cycles per second as well as the electric current at each polarity to provide a series of time and current defined polarity cycles for D.C. arc welding apparatus.Type: GrantFiled: April 5, 1994Date of Patent: November 7, 1995Assignee: General Electric CompanyInventors: Gilbert E.
