The present invention provides a method of commemorating at least one special date for an individual with a customized jewelry design. The method comprises selecting at least one day, from numbers 1 through 31, and at least one month, from numbers 1 through 12, that the individual wishes to commemorate; placing at least one first design element which corresponds to the at least one selected day on a base element, said base element divided into sixty visible or invisible segments to represent a clock face with a top point on the clock face representing noon or midnight and referred to as a zero point, wherein the placement of the at least one first design element represents at least one minute hand of the clock and placing at least one second design element which corresponds to the at least one selected month on the base element, wherein the placement of the at least one second design element represents at least one hour hand of the clock. The customized jewelry may include, without limitation, pendants, earrings, bracelets or rings.

Method of custom designing a jewelry article to commemorate a special date

A case for a gas turbine engine includes a cast case section cast case section configured to be welded between a forward case section and an aft case section.

Forged cast forged outer case for a gas turbine engine

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.

Sealing interface for a case of a gas turbine engine

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.

Turbine case adjustment using Adjustable tie rods

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.

Pinned seal

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.

Method for centering bearing compartments

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.

Gas turbine engine mid-turbine frame tie rod arrangement

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.

Support assembly for a gas turbine engine

Systems and methods for centering bearing compartments

A bearing assembly for a gas turbine engine includes a bearing, an outer assembly disposed about an axis and having an angled perimeter, and an inner assembly supporting the bearing and having a surface angled to slide against and attach to the angled perimeter as the bearing is aligned with the axis.

Mid-turbine bearing support

An assembly for dampening vibration movement between a cylinder and a concentric duct, where the cylinder is positioned radially inside the duct, includes a damper attached to the duct. The damper includes a housing attached to the duct, a contact member positioned at least partially inside the housing and having a contact surface adjacent an outer surface of the cylinder, and a cap threadedly engaged with the housing for applying a load on the contact member in a direction toward the cylinder.
