Abstract: L'invention concerne un procédé de déposition électrolytique de couches de cuivre, notamment sur des plaquettes de circuits imprimés, caractérisé par les étapes suivantes. On met un substrat électroconducteur et des anodes qui se dissolvent pendant la déposition électrolytique en contact avec un bain de déposition qui contient des ions de cuivre, des composés qui augmentent la conductivité électrique du bain de déposition, des additifs qui modifient les propriétés matérielles des couches de cuivre, des composés additionnels faisant partie d'un système oxydo-réducteur électrochimiquement réversible et des solvants ou des mélanges de solvants. On connecte le substrat et les anodes à une alimentation en courant et on dépose les couches de cuivre sur le substrat par un procédé à courant ou à tension pulsés. Ce procédé permet de déposer des couches métalliques avec de bonnes propriétés optiques et mécaniques déjà après un temps de séjour dans le bain très court.

Title: Method and apparatus for enhancing gas turbo machinery flow
Inventor: NORRIS THOMAS R
IPC: F01D25/30
Filed: 1998-03-17
Granted: 2010-02-09
Abstract: In a conduit (D) constituting the outlet from turbo machinery such as a turbine or compressor, stall gas (G0, G7) high static pressure and low velocity is collected. This stall gas is then routed through struts (S) - preferably teardrop shaped - to more central low static pressure and high velocity gas flow areas. At these areas, the gas is discharged, preferably through multiple manifold openings (24). Mixing of the collected high static pressure, low velocity stall gas with the low static pressure, high velocity main stream gas occurs. Turbine noise, vibration, and back pressure are decreased with resulting improvements of efficiency. Variations are illustrated including adaptation of gas flow transfer utilizing turning vanes (72), fairings, rectangular duct turns (fig. 5a, b), and struts (fig. 6c) for placement in turbine turbo machine outlets having high turbulence or variable swirl.

Title: Ostomy or incontinence pouch
Inventor: STEER GRAHAM E
IPC: A61F5/445

Granted: 2008-10-07
Abstract: An ostomy pouch (10) is defined by a front wall (12) and a rear wall (14) having a stoma aperture (18). One or more rupturable capsules (24) are carried on a carrier or intervening wall (44) welded to the front and rear walls at a common weld seam (16). When desired, a capsule (24) can be ruptured by squeezing, the pouch wall together at that position, to dispense the contents (for example, a deodorising agent, a disinfectant or a preservative). In one form, the carrier does not cover the stoma aperture. In another form, the contents are dispensed on the side facing the front wall (12), and the curtain (44) shields the stoma aperture (18), to prevent the agent spurting out or contacting the stoma. In another form, one or more rupturable capsules may be arranged on the front wall (12) or on the rear wall (14). A plurality of the capsules (24) may contain different agents if desired. In another form, one or more self-dissolving capsules, for example, of gelatine, may be introduced into the pouch to dispense the agent in response to environmental conditions (for example, temperature/humidity) within the pouch.
