Abstract: The disclosure describes a device (1) including a housing (11, 12) having an inlet (2) and an outlet (3) and defining a flow path for a liquid between the inlet (2) and the outlet (3). The flow path extends through a purification bed (17) which operates to remove substantial quantities of dissolved substances from the liquid. The purification bed (17) may include a plurality of separators (5) which act to increase the velocity of liquid flow through the purification bed (17). A filter may be located in and around the periphery of the housing (14, 15) and downstream from the purification bed. The filter (14, 15) is preferably pleated and has an absolute pore rating no greater than about 0.8 mu m to remove many microbiological organisms from the liquid. The disclosure further describes a method for manufacturing the device.

Abstract: This invention relates to the field of liquid dispensing and metering devices that dispense a solution in drop form and protects the solution from contamination. In applications where contamination and proper dosage is a concern, the prior art discloses dispensers related both to the use of anti-bacterial agents added to the solution to prevent contamination and the use of a single dose device. Both present problems, as the addition of the agent causes allergic reactions in some users, while the single dose device is inconvenient to the frequent user. Prior art dispensers also do not permit control of metering for proper dosage. This invention solves these problems by providing a filter in the dropper portion of the device to prevent contamination of the solution. The device includes a dropper (2) having an outlet (3) and filter (4). The filter is a composite consisting of a liquophilic component (5) and a liquophobic component (6).

Abstract: An apparatus and method for removing one or more undesirable components from a gas using a sorbing apparatus (10) having at least one chamber (11) (12) with first ports (11a) (12a), and second ports (11b) (12b) defining a gas flow path therebetween. A sorbent bed (13) (14) having a sorbing region (13a) (14a) of a first sorbent material and a guard region (13b) (14b) of a second sorbent material is disposed in sorbing chamber (11) (12). A gas control arrangement (15) cyclically (a) directs influent gas through first port (11a) (12a), sorbing region (13a) (14a), guard region (13b) (14b) and out second port (11b) (12b) wherein the undesirable components are sorbed from the influent gas and (b) directs a purge gas in the opposite direction through sorbing chamber (11) (12) for regeneration. Gas control arrangement (15) cycles the influent gas and the purge gas through sorbing chamber (11) (12) so as to sorb and desorb the undesirable components substantially entirely in sorbing region (13a) (14a) whereby guard region (13b) (14b) serves as a safeguard for sorbing region (13a) (14a).

Abstract: Un procédé de filtration permettant d'obtenir un filtrat d'effluents clairs à partir d'un fluide de traitement de puits de pétrole ou de gaz troubles contaminés avec des particules solides constituées de débris de forage et de formation ayant des dimensions de particules comprises entre 0,1 et 30 microns environ, consiste à faire passer le fluide de traitement au travers d'un filtre ayant une grosseur des pores d'environ 40 microns ou moins avec une densité d'écoulement comprise entre 0,05 environ et 0,5 galons par minute par pied carré de surface filtrante de sorte que 1) au début au moins une partie des particules est récupérée sur la surface amont du filtre et un gâteau de filtration commence à se former, avec possibilité d'enlever les particules plus petites que la grosseur absolue des pores de cette surface filtrante et 2) ensuite le fluide de traitement est filtré au travers d'un composite filtrant du filtre superficiel et du gâteau de filtration, ce qui permet d'obtenir un effluent clair sensiblement exempt de matériaux particulaires solides ayant des dimensions de particules de l'ordre de 0,1 à 30 microns ou davantage, et la longévité du filtre est améliorée. Le procédé s'applique en particulier au traitement de fluides de complétion et de stimulation utilisés dans des puits de pétrole et de gaz.

Abstract: A multiple cartridge filter assembly is provided with a removable filter array to facilitate the rapid replacement of an entire array having spent cartridges with another identical array having fresh cartridges, after which the spent cartridges of the removed array may be replaced. The removable filter array includes a separation plate from which the filter cartridges hang suspended in sealing engagement therewith and a dual position support platform connected to the separation plate and located beneath the lower blind ends of the cartridges. The support platform maintains the cartridges sealingly engaged with the separation plate when the removable array is in its working condition but automatically drops down relative to the separation plate when the array is removed to accommodate the replacement of the cartridges. In the preferred practice of the invention the movement of the support platform relative to the separation plate is limited to that which permits removal of the filter cartridges at an angle but not vertically.
