Abstract: Systems and methods for selectively recovering a target metal from an ion exchange resin are generally described. In certain embodiments, such methods and systems can be employed for metal purification and enrichment of target metal species from mixtures containing contaminating or non-target metals. In some embodiments, ion exchange is accomplished in the presence of one or more species that facilitate the recovery of a metal from a composition further comprising one or more other metals. The recovered metal-containing composition may contain the recovered metal at relatively high purity and/or in relatively large amounts. In some embodiments, the conditions present during ion exchange are varied in a manner that facilitates the enrichment of a metal from an initial (e.g.

Abstract: Sealing film having a substantially longitudinal central strip to be torn out between a first end and a second end, whereby the central strip has a substantially constant width and a substantially longitudinal central axis, and whereby an end of the central strip adjacent to one end selected from the first end and the second end has a width which varies from the substantially constant width of the central strip to an end width lower to the substantially constant width of central strip.

Abstract: A device for coating an element is described. The device is capable of bearing and using a swab impregnated with a coating composition and includes a mobile carriage for bearing the swab. The carriage is movable along a guiding path. The device further includes an element for pushing the swab towards the element to be coated so that a quantity of the composition released from the swab coats an element. The device also includes an element for distributing the composition, so that the coating is substantially uniform.

Abstract: Sealing member formed by a sealing film with a substantially longitudinal portion to be torn out, wherein the sealing film is connected to a pulling strip made of a layer, with fibers extending in a direction forming an angle between −60° and +60° with respect to the tearing direction of the longitudinal portion to be torn out.

Abstract: A sealing film for a toner cartridge or container. The sealing film has a layer with a thickness of between 20 &mgr;m and 1 mm and has at least on substantially linear tearing direction. The layer also includes surface elements that extend in a direction that is different from the preferred tearing direction of the sealing film.

Abstract: The present invention provides a sealing film for a toner cartridge. The sealing film includes a layer with a preferred linear tearing direction. The layer is provided with longitudinal surface elements defining a strip to be torn out. The longitudinal surface elements extend in an inclined direction with respect to the strip to be torn out. The strip to be torn out includes a pulling means having a sufficient tearing resistance for preventing a separation between the pulling means and the strip to be torn out during a tearing operation.

Abstract: Sealing member for toner container, said member with a tearable central strip being associated to a means ensuring the pressing of the lateral portions of a compressible cleaning element, with respect to the portion of the cleaning element intended for cleaning the torn central strip.

Abstract: Sealing member comprising a sealing film with a substantially longitudinal portion to be torn out, wherein the film is connected to a pulling means comprising at least a layer comprising fibres extending in a direction forming an angle comprised between −60° and +60° with respect to the tearing direction of the longitudinal portion to be torn.

Abstract: In the present invention of Correlated Modulation Imaging (CMI), the weak optical image signal (and therefore the signal current) is modulated, and the signal integration direction is correlated to the modulation. Therefore, the dark and/or background current, which are not modulated, are cancelled, while the signal current is integrated. As a result, the total integration time of the signal of each pixel is increased, and its signal to noise ratio and dynamic range are improved. Besides, the CMI noise spectrum peaks at the modulation frequency, and therefore, the detector's 1/f and other low frequency noises can be suppressed. In the present invention, the method and theory of CMI, as well as the means and steps for the realization of CMI, are explicitly developed. Two versions of CMOS devices (CMI unit pre-amplifier version 1 and 3), with their circuitry design and testing data are presented as the critical component for correlated modulation imaging.

Abstract: Member for a printer, a fax machine, a copier or a toner cartridge, in which said member has a face in contact with toner particles, said face being provided with a top layer in contact with toner particles, said top layer comprising substantially spherical particles with a Mohs hardness of more than 3 or equal to 3 and an average particle size lower than 100 &mgr;m.

Abstract: A process is presented for recycling a toner cartridge, including a used magnetic roller and a used doctor blade. The process requires: (1) removal of the doctor blade and magnetic roller from the cartridge; (2) treatment of the doctor blade to restore the shape of said doctor blade; (3) coating of the doctor blade and magnetic roller with an antistatic and anti abrasive coating; and (4) placement of the doctor blade and magnetic roller back into the cartridge. Additional processes involving reuse of other toner cartridge components are also described.
