Abstract: The present invention provides customized jewelry designs for pendants, earrings bracelets, rings and other pieces of jewelry that display a specific time or specific calendar date on the piece of jewelry to commemorate a special time or calendar date. The piece of jewelry is invisibly divided into sixty segments and one or more sets comprised of two design elements are placed on the surface of the jewelry. The first design element of the one or more sets is positioned on the jewelry at one of the sixty segments and represents an hour hand of a clock. The second design element of the one or more sets also is positioned on the jewelry at one of the sixty segments and represents a minute hand of a clock. The placement of each of the one or more sets of design elements may represent one or more specific times, or the one or more specific times may represent one or more calendar days, i.e., the number of the month and the number of the day which has been transposed into one or more specific times on the clock.

Abstract: A case assembly for a gas turbine engine, includes a case with a case boss, said case boss including a peripheral wall that defines a first inner diameter in a first condition to receive a piston seal, and a second inner diameter in a second condition, the second condition including enlargement of the first inner diameter to form a second inner diameter and a bushing mounted within the second inner diameter, an inner diameter of the bushing defines a bushing inner diameter about equivalent to the first inner diameter to receive the piston seal.

Abstract: A turbine housing section includes a radially inner case centered on a first axis, and a radially outer case spaced radially outwardly of the inner case, and centered on a second axis. The first and second axes are offset relative to each other. A plurality of tie rods include a threaded nut received on a tie rod, with the plurality of tie rods connecting the inner and outer cases. The plurality of tie rods are spaced circumferentially about both of the first and second axes, and extend for distinct lengths between the inner and outer cases such that the inner and outer cases are held at a position wherein the first and second axes are offset.

Abstract: A disclosed gas turbine engine includes a compressor section, a combustor section, a first turbine section and a second turbine section. An outer case structure for the gas turbine engine includes a single-piece case structure with a turbine case portion and a transition case portion. The transition case portion is integrally formed with the turbine case portion as a single part module. A combustor case houses the combustor and an aft turbine case supports the low pressure turbine. The outer case includes a forward end attachable to the combustor case and an aft end attachable to the aft turbine.

Abstract: An assembly includes a case structure, a seal interfacing with the case structure, a first pin, and a main pin hole on one of the seal and the case structure. The first pin extends through the main pin hole and is fixed relative to the other of the seal and the case structure. The assembly also includes a second pin and a secondary pin hole on one of the seal and the case structure. The second pin extends through the secondary pin hole. A cross-sectional gap area between the second pin and the secondary pin hole is greater than a cross-sectional gap area between the first pin and the main pin hole. Also included is a bolt hole on one of the seal and the case structure. The bolt hole is circumferentially located between the main pin hole and the secondary pin hole.

Abstract: Systems and methods are disclosed herein for dressing centering a bearing compartment in a gas turbine engine. A nut may be inserted through an outer case of a gas turbine engine. The nut may be coupled to a strut which centers a bearing compartment. The nut may be rotated to achieve a desired tension on the strut to center the bearing compartment. A retaining plate comprising a collar may be positioned over the nut. A swaging tool comprising a swaging ramp may be positioned over the nut. The swaging tool may be forced against the retaining plate using a draw-in bolt. The swaging ramp may contact the collar and form indentations in the collar to lock the nut in place.

Abstract: A gas turbine engine mid-turbine frame includes an annular case that has a hole. A tie rod with a first end extends through the hole. The first end includes a threaded portion. A nut is secured to the threaded portion to clamp the tie rod to the annular case. A tab washer is arranged between the nut and the annular case. The tab washer interlocks the nut to the case to prevent relative rotation therebetween.

Abstract: A support assembly for a gas turbine engine includes at least one inner support that extends about a circumferential axis and defines a cavity for receiving a control ring. At least one cover plate is attached to at least one inner support to enclose the cavity. At least one of the inner support and the cover plate includes a rail and the other of the inner support and the cover plate includes a groove for engaging the rail.

Abstract: An electrical enclosure wherein an electrical component can be moved between various positions (e.g., connected, disconnected, test, etc.) without opening an enclosure door. The electrical enclosure supports a component for movement between a withdrawn position, a test position, and an inserted position. A handle is accessible by an operator from an exterior of the enclosure and is configured to move the component between the respective positions without having to open the enclosure. The handle is integral with the enclosure and thus an operator needs no special tool or other device to effect movement of the electrical component between its respective positions.

Abstract: A gas turbine engine mid-turbine frame includes inner and outer cases that are arranged about an engine axis. A radial plane is arranged normal to the engine axis.
