Title: Assembly for filtering pressurized fluids and method and system of using the same
Inventor: MAYBERRY JOE L
IPC: B01D35/30
Filed: 1998-12-11
Abstract: Filter assembly (100) for filtering pressurized fluid removed from a fluid system having undesirable levels of contamination, such as a dry cleaning system. The filter assembly (100) has an upstream connection (110) in fluid communication with the fluid system to remove contaminated pressurized fluid therefrom. A plurality of filter lines (120, 130, 140) are in fluid communication with the upstream connection (110). The plurality of filter lines are connected in parallel with each other for concurrent flow of the pressurized fluid therethrough. Each filter line has a strainer (122) and at least one insoluble contaminant filter connected in series (124). Additional filter elements may be provided. The filters have housings with crossdimensions substantially similar to those of the filter lines and the other piping used throughout the fluid system. A downstream connection (150) is provided in fluid communication between the filter lines and the fluid system such that pressurized fluid removed from the fluid system flows from the upstream connection (110) and in parallel through the filter lines (120, 130, 140) before returning to the fluid system through the downstream connection (150).

Patent CA-2325808-A1 (CA)
Title: Method and apparatus for continuous casting of metals
Inventor: BESSHO NAGAYASU
IPC: B22D11/115
Filed: 2000-11-14
Abstract: During continuous casting of metals, a non-moving, vibrating magnetic field is applied to a molten metal in a casting mold to impose only vibration on the molten metal. This continuous casting method can produce a cast slab much less susceptible to flux entrainment, capture of bubbles and non-metal inclusions near the surface of the molten metal, and surface segregation. The magnetic field is preferably produced by arranging electromagnets in an opposing relation on both sides of the mold to lie side by side in the direction of longitudinal width of the mold, and supplying a single-phase AC current to each coil. The single-phase AC current preferably has frequency of 0.10 to 60 Hz. A static magnetic field can be applied intermittently in the direction of thickness of a cast slab.      This technique can produce a cast slab substantially free from the flux entrainment and the surface segregation. Preferably, the static magnetic field is intermittently applied under setting of an on-time t1 = 0.10 to 30 seconds and an off-time t0 = 0.10 to 30 seconds. Also, the static magnetic field is preferably applied to the surface of the molten metal.

Filed: 2000-12-27
Abstract: Il est connu que la majorité des machines utilisent de l'énergie non renouvelable.  Dans la présente invention, la Centrale en question utilise de  L'ÉNERGIE POTENTIELLE des liquides selon le principe d'Archimède.  Cette Centrale est constituée d'un bassin plein de liquide, et de deux roues dentées sur lesquelles est enroulée une chaîne sans fin qui comporte des cloches qui seront remplies simultanément dans le fond du bassin avec de l'air comprimé fournie par des compresseurs, ou par du gaz sous pression récupéré au fond de la mer où on trouve des fumeurs de gaz. Ces cloches reçoivent une plus forte poussée en route de bas en haut quand le gaz qui y est injecté gagne en volume avec la baisse de pression, selon la hauteur où elle se trouve, ce qui engendre le déplacement d'une plus grande quantité de liquide où la poussée est égale au poids du liquide déplacé.
