Title: Procede de rechargement local de piece thermomecanique endommagee et piece ainsi realisee, en particulier piece de turbine
Inventor: HUGOT JULIETTE
IPC: B22F5/00
Filed: 2012-03-06
Abstract: La présente invention vise à pallier les inconvénients de l'état de la technique en proposant de réaliser de manière simple, rapide et efficace des frittés précis en 3 dimensions (3D) de forme sensiblement proche de celle de la pièce originelle. Pour ce faire, l'invention fait intervenir un frittage flash produit par la technologie SPS (« frittage flash de plasma » en terminologie anglaise). Selon un mode de réalisation, un moule (1 ) est réalisé dans une matrice (1 1 ) d'enceinte SPS à frittage flash, le moule (1 ) ayant une forme d'empreinte de la pièce originelle. Sont déposées en couches successives dans le moule (1 ) : une couche (31 ) à base de poudre de superalliage, une couche de protection métallique (32) et une couche de barrière thermique (33). Dans une étape de frittage, une mise en pression est déclenchée et un passage de courant puisé induisant une montée rapide en température selon un cycle de frittage flash réglé en température, en pression et en durée, avec au moins un palier de température et un palier de pression. La couche de superalliage (31 ) forme par diffusion, lors de l'étape de frittage, un ancrage de continuum de matière avec la pièce à recharger (2).

Title: Multi flow multi venting nipple
Inventor: RICHARD MAXIME R
IPC: A61J11/02
Filed: 2013-10-02
Abstract: A multi flow multi venting nipple includes a teat having a flow aperture which allows for at least two different flow rates depending upon the operative radial orientation of the nipple. The nipple further includes a number of vent apertures, equal to the number of flow rates, formed by check valves extending through the nipple to reduce negative pressure during use. Each vent aperture is associated with a particular flow rate, and is radially oriented to be uppermost and vertically above the flow aperture during use at such flow rate. All vent apertures will be operable at once. The nipple further includes safety walls extending from the nipple and surrounding at least half the periphery of each check valve forming the vent apertures. The safety wall prevents unintentional and rough contact from damaging the check valves.
