    Abstract: An apparatus for delivering high pressure cooling air to the turbine rotor blades of a turbo machine comprises a plurality of circumferentially spaced, forward bleed openings formed in the combustor inner casing or inner wall of the combustor inner passage of the turbo machine which are effective to reduce separation of the air flow directed through the combustor inner passage and thus reduce turbulence and pressure losses therein.

    Abstract: A method for applying preselected abrasive particles to a cleaned first article surface adjacent a second article surface selected to be substantially free of such abrasive particles includes disposing on the first article surface a first electrically non-conductive tape segment including pores large enough to allow passage of electrodeposition current and electrolyte solution but smaller than the size of abrasive particles to be retained on the first tape segment. The first segment has a porous adhesive layer of relatively low tack level, the adhesive carrying the abrasive particles through a first, relatively weak bond. A second electrically non-conductive tape segment substantially impervious to electrolyte solution and electroplating current and having adhesive on a second segment operating surface is disposed on the second article surface in a manner at least sharing an edge portion with the first segment. A metallic coating is electrodeposited through pores of the first tape segment onto the first article surface and about the abrasive particles held in contact with such surface to bond the particles to the first article surface through a second bond. Such bond between the metallic coating and the abrasive particles is stronger than the first, relatively weak bond. The first tape segment is separated at the first bond from the abrasive particles which remain bonded to the first article surface. An improved electroplating tape is a multisegment electrically non-conductive tape comprising the first tape segment and at least one second tape segment at least sharing an edge portion with the first tape segment.

    Abstract: A hermetically sealed housing (10) for a solid state device or the like includes a metal header (12) having a mounting surface (14) and a metal cap (20) mounted on the header and over the mounting surface. The cap includes a cup-shaped portion and a flange (24) extending radially outwardly from the rim of the cup-shaped portion. A weld ring (26) projects from a surface of the flange toward the header mounting surface and is welded to the mounting surface (14).A second ring (30) projects from the surface of the flangeand is spaced radially inwardly from the weld ring. The second ring (30) is shorter than the weld ring (26) so that it preferably just contacts the mounting surface of the header. The second ring captures any metal particles (34) splashed from the weld ring during the welding of the cap to the header and thereby minimizes particle induced noise.
