Title: Traitement de surface d'alliages a base de ni-fe-cr austenitiques
Inventor: PALUMBO GINO
IPC: C21D10/00
Filed: 2001-11-23
Abstract: L'invention concerne un procédé de traitement de surface permettant d'améliorer la résistance à la corrosion intragranulaire et à la fissuration intragranulaire des composants fabriqués à partir d'alliages à base de Ni-Fe-Cr austénitiques. Ce procédé consiste à déformer la surface d'un composant dans une profondeur variant de 0,01 mm à 0,5 mm, par exemple par grenaillage de précontrainte à intensité élevée en dessous de la température de recristallisation, suivi d'un traitement thermique de recristallisation, de préférence à des températures de solution. La déformation de surface et le processus de recuit peuvent être répétés afin d'optimiser la microstructure de la zone à proximité de la surface. Suite au traitement thermique final, ce processus peut éventuellement consister à effectuer une autre déformation (travail) de surface à intensité réduite, à obtenir une profondeur travaillée comprise entre 0,005 mm et 0.01 mm afin de comprimer résiduellement la zone à proximité de la surface afin d'améliorer la résistance à la fissuration.

Title: Use of polymer as flocculation aid in membrane filtration
Inventor: CADERA JASON
IPC: C02F1/56
Filed: 2003-09-30
Abstract: A method of filtering a feed of water to provide potable water includes adding a coagulant to the water to be filtered to encourage the formation of flocs. About 0,.1 to 1 mg/L of a polymeric flocculation aid is also added to the water to be filtered to further encourage the formation of flocs. Some of the flocs may then removed from the water to be treated, for example with a clarifier. A filtered permeate is removed from the water to be treated with a membrane filtration device. The membrane filtration device may be an immersed suction driven membrane filtration device. The polymeric flocculation aid may be added to the body of water in a dosage between about 0.2 and 0.5 mg/L. The dosage of the polymeric flocculation aid may also be approximately equal to the dosage which gives the minimum turbidity of the water to be treated, for example, as determined by jar testing.

Title: Appareil a jet d'eau ultrasonique
Inventor: VIJAY MOHAN M
IPC: B05B15/00
Filed: 2003-11-03
Abstract: L'invention porte sur un appareil à jet d'eau ultrasonique (10) possédant un module générateur mobile (20) et tuyau d'eau haute pression (40) pour délivrer l'eau haute pression du module (20) à un pistolet à main (50) avec déclencheur et une buse ultrasonique (60). Le générateur ultrasonique du module (20) transmet des impulsions électriques haute fréquence à un transducteur piézo-électrique ou magnétostrictif (62) qui vibre pour moduler un jet d'eau haute pression s'écoulant dans la buse (60). Le jet d'eau sortant de la buse ultrasonique (60) est pulsé sous forme de mini masses d'eau, chacune conférant une pression par martèlement de l'eau sur une surface cible. L'appareil à jet d'eau ultrasonique (10) peut être utilisé pour découper et ébavurer des matériaux, ou nettoyer et décaper des surfaces et briser des roches. L'appareil (10) effectue ces tâches avec un plus grand rendement que des systèmes à jet d'eau traditionnels à écoulement continu du fait de l'effet répétitif du martèlement de l'eau. Une buse à plusieurs orifices de sortie ou une buse rotative (76) peut être ménagée à la place d'une buse à un seul orifice de sortie afin de rendre le nettoyage et le décapage de grandes surfaces plus efficaces. Une vanne de décharge de l'eau (27) et un solénoïde de commande sont placés dans le module du générateur mobile (20) plutôt que dans le pistolet (50) afin de rendre le pistolet plus léger et plus ergonomique.

Title: System for mixing and dispensing concrete
Inventor: CHRISTENSON RONALD E
IPC: B28C5/42
Filed: 1990-03-30
Abstract: ABSTRACT OF THE DISCLOSURE An assembly which is adapted for mounting inside a mixing drum and a mobile system for mixing and dispensing concrete includes fin structure for mixing and guiding a substance when the mixing drum is rotated.  The fin structure is constructed of a lightweight polymeric material which is resistant to abrasion and is many times lighter than steel.  As a result, the weight of such a system is reduced in comparison to systems which were heretofore known.  Preferably, the fin structure is fabricated from a polymer which tends to wear smooth rather than rough, which increases the cleanability of the fin structure over its entire design life.  Novel structure for securing the fin structure to an outer wall of the mixing drum is also disclosed.
