A combustor assembly for a gas turbine engine includes a dome having a forward surface and an inner surface. The forward surface and the inner surface of the dome at least partially define a slot. The combustor assembly also includes a liner at least partially defining a combustion chamber and extending between an aft end and a forward end. The forward end of the liner is positioned within the slot of the dome. The forward end of the liner includes an axial interface surface and a radial interface surface. The axial interface surface defines a radial gap with the inner surface of the dome and the radial interface surface defines an axial gap with the forward surface of the dome. At least one of the radial gap or the axial gap is less than about 0.150 inches during operating conditions of the combustor assembly to prevent an undesirable airflow.

Components and methods for forming components are provided. For example, a method for forming a component includes laying up a plurality of plies to form a component preform that defines an axis of symmetry and a circumferential direction. Laying up the plurality of plies includes overlapping ends of the plurality of plies to define overlap regions and offsetting the overlap regions along the circumferential direction such that any radial line drawn from the axis of symmetry through the plies passes through only one overlap region. In another embodiment, a component includes a body that is symmetric about an axis of symmetry and that defines a circumferential direction and a radial direction. The body is formed from a plurality of plies and has a substantially uniform thickness. Ends of the plurality of plies are overlapped to define a plurality of overlap regions, which are offset along the circumferential direction.

The invention relates to an electrode-inlead assembly for electrical lamps which comprises a lead-in-wire connected to a foil made of refractory metal and the foil is connected to a shank made of refractory metal and supporting the electrode. The object of the invention is, that the shank is made of two parallel rods which are joined by their one end portions, and their opposite end portions are welded to the foil, so that the foil is sandwiched between the rods.

A high pressure discharge lamp with a thermally improved anode, as well as a method of making such a lamp, are disclosed. The lamp includes a refractory arc tube with a hermetically sealed arc chamber, a fill in the arc chamber for facilitating light generation, and an anode and a cathode extending into the hermetically sealed arc chamber and being spaced apart from each other. The anode comprises a shank of refractory metal, a cylindrically shaped refractory metal sleeve on a portion of the shank, and an end proximally facing the cathode. The anode end comprises a substantially solid mass of refractory metal, and is integrally joined to both the shank and the metal sleeve to facilitate heat flow from the anode end to the shank and sleeve. The anode end preferably is generally shaped as a hemisphere facing the cathode. The refractory metal sleeve is preferably one or more layers of a helically wound refractory metal wire having an outer diameter more than twice a diameter of the shank.

The present invention is a method for performing a joining operation to couple a first component to a second component. One embodiment of the present method includes the steps of aligning the first component and the second component so that a first portion of the first component is aligned with a first portion of the second component, heating the first component so that a melt is formed at the first portion of the first component, and forcing the first portion of the second component into the melt so that when the melt solidifies, the first component and the second component are bonded.

Method for welding components

The present invention is an apparatus for performing a joining operation to couple a first component to a second component. One embodiment of the present apparatus includes means for aligning the first component and the second component so that a first portion of the first component is aligned with a first portion of the second component, means for heating the first component so that a melt is formed at the first portion of the first component, and means for forcing the first portion of the second component into the melt so that when the melt solidifies, the first component and the second component are bonded. In the exemplification embodiment, the heating means is an Nd:YAG laser source which emits at least a first laser beam which impinges upon one of the components.

This coupling means comprises a sleeve containing a bore in which is located a bundle of optical fibers, at least some of which are of compression-deformable material. The input ends of the fibers, which receive light from a light source, are located in a predetermined plane. The bore tapers from a relatively large diameter at a location in a second plane spaced from said predetermined plane to a relatively small diameter at said predetermined plane. The tapered bore is of such a size that the optical fibers therein are laterally compressed and the compression-deformable fibers are so deformed in transverse cross-section relative to their normal cross-sections that the fibers more completely fill the bore in its relatively small diameter region than in said second plane.
