20150151678 | FLAT DIAL WITH 3D APPEARANCE - A dial assembly is provided that includes a dial surface including a flat surface and a plurality of lines formed on the flat surface projected from a 3D object that generate a 3D appearance. One or more light sources illuminate each of the lines of the plurality of lines. A method of forming a dial assembly is also provided. The method includes dividing a subject 3D dial with a plurality of equidistant planes and projecting edges of the planes onto a flat dial surface to form a plurality of lines to generate a 3D appearance on the flat dial surface. | 06-04-2015 |

20140255169 | GAS TURBINE INCLUDING BELLYBAND SEAL ANTI-ROTATION DEVICE - A turbine including a plurality of stages, each stage including a rotatable disk and blades carried thereby. An annular gap defined between a pair of adjacent rotatable disks. A sealing band is located in opposing sealing band receiving slots formed in the adjacent disks to seal the annular gap, the sealing band including band engagement structure. A disk engagement structure is defined in the pair of adjacent rotatable disks. The disk engagement structure extends axially into the pair of adjacent rotatable disks and circumferentially aligns with the band engagement structure. A clip member is positioned in engagement with the sealing band through the band engagement structure and in engagement with the pair of adjacent rotatable disks through the disk engagement structure. The clip member restricts movement of the sealing band in only a circumferential direction of the slots. | 09-11-2014 |

20100308578 | Pipe Coupling with Multi-combed Self-pressurizing Seals - This invention relates to pipe coupling with multi-combed, self-pressurizing internal seals and an integral pipe fastening system to join and seal pipes of all sizes, fluid contents and line pressures. The invention embodies a coupling body, two pressure responsive seals installed in recessed seal grooves located at opposite outside edges of the pipe coupling body, and seal body consisting of a unidirectional fluid inlet and internal pressure responsive chamber and an external sealing surface comprised of several resilient, multi-combed and conjoined lips and fluid pockets which form a series of redundant seals around the outside axial surface of pipes joined within the coupling. Fluid escaping from the pipe juncture enters the internal pressure responsive chamber through the unidirectional orifice wherein trapped fluids expand the pliable external multi-combed seal surface against the axial surface of each pipe with corresponding force to prevent the outward flow of fluid from the pipe coupling. | 12-09-2010 |
20110241342 | Pipe Repair Clamp with Self Pressurizing Seal - The invention provides a faster, safer, more reliable and cost-effective method to permanently or temporarily repair leaking in-service pipes than welding and other devices and methods currently used to repair leaking pipes. The interlocking pipe clamp and internal circumferential self-pressurizing seal, installed in a recessed seal groove within the clamp housing, embodies a unidirectional fluid orifice leading to an internal pressure responsive chamber whereby trapped fluids inside the chamber expand outwardly under pressure to force the external sealing surface of several pliable, multi-combed and conjoined fingers to form a series of redundant seals against the leaking pipe with increasingly greater force to prevent the escape of fluids from the pipe and to prevent seal dislodgement from the pipe repair clamp. The seal material is composed of resilient synthetic and natural materials which are corrosion and fire resistant and color coded for specific fluid repair applications. | 10-06-2011 |
