Patent number: 11840005Abstract: Plastic profile extrusion system includes an extrusion die that pre-forms a hot, unfrozen plastic profile shape. Cooled calibration device receives the hot plastic in a longitudinal cavity through the calibration device to conductively cool the plastic as it holds the plastic profile to size and dimensions. For plastic parts with channels, inside corners, or other difficult to cool sections, the calibration device would require a metal ridge to hold the shape of that channel or corner as the heat is conducted from the hot plastic through the metal ridge into the body of the calibration device. This invention replaces metal ridges that hold the shape of the plastic profile during cooling in at least part of the calibration device with fluid cooling passages that communicates with the moving portion of the plastic profile and cooling medium to fill the flow passages to extract heat from the plastic material.Type: GrantFiled: September 16, 2019Date of Patent: December 12, 2023Assignees: Innovative Plastic Products, Inc., Innovative Plastic Products, Inc.Inventor: Randall J. Brown

Patent number: 10801346Abstract: An annular finger seal includes a base portion defining a base edge of the annular finger seal and having a center pass-through aperture. The base edge may be substantially continuous. The annular finger seal may also include a finger portion defining a finger edge of the annular finger seal and including a plurality of fingers. The finger edge may be segmented by gaps disposed between adjacent fingers of the plurality of fingers. A gas turbine engine includes a combustor section, a turbine section, and an annular finger seal. The annular finger seal includes a plurality of fingers and the annular finger seal is disposed at an adjoining interface between the combustor section and the turbine section. The annular finger seal may be mounted to the turbine section and may engage a radially inward facing surface, relative to the engine central longitudinal axis, of the combustor section.Type: GrantFiled: August 1, 2016Date of Patent: October 13, 2020Assignee: Raytheon Technologies CorporationInventors: Kevin W. White, Henry K. Webster, Jonathan Ariel Scott, Randall J. Brown, Alan D. Lees

Patent number: 9115591Abstract: A seal for a gas turbine engine is shown. The engine may have a first vane for imparting a first twist to air passing thereby and/or a second vane for imparting a second, different twist to air passing thereby, each of the first and second vanes having a mounting area for mounting the seal thereto. The seal includes a top, a bottom, a left side, a right side a back, and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side so that the seal may mate with the mounting area of the first vane and, if the seal is inverted, may mate with the mounting area of the second vane.Type: GrantFiled: August 30, 2011Date of Patent: August 25, 2015Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Bradley T. Duelm, Randall J. Brown, Nathan A. Shirk, Lewis M. Holby
