Abstract: The present invention relates to a method and a device for displacing a moving body (4) on a base (2) mounted elastically with respect to the ground (S), the moving body (4) being displaced linearly with a predetermined displacement under the action of a controllable force (F). According to the invention: a) a mathematical relationship illustrating the movements of the entity formed by the base (2) and the moving body (4) is defined; b) using said mathematical relationship there is determined a force (F) which, applied to the moving body (4), produces a combined effect on the moving body (4) so that it performs said predetermined displacement, and on the base (2) at least so that it is immobile at the end of the displacement of the moving body (4); and c) the force (F) thus determined is applied to the moving body (4).

Abstract: One aspect of the present invention is a removable ink supply for forming a fluid connection with a fluid inlet of an ink-jet printer into which the ink supply can be installed. The ink-jet printer has a fluid conduit for supplying liquid ink to an ink-jet printhead. The removable ink supply includes a quantity of liquid ink and a fluid outlet. The fluid outlet includes (i) a hollow boss having a first end in fluid communication with the quantity of liquid ink, a neck formed in a second end of the boss, the neck defining a scaling surface and an opening; (ii) a sealing member positioned within the boss, the sealing member being movable between a first position in which the sealing member seals the opening and a second position in which liquid ink can flow through the boss opening; and (iii) a biasing structure for biasing the sealing member toward the first position. The ink supply is adapted for installation in the fluid inlet of the ink-jet printer.

Abstract: An ink supply for an inkjet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir, which has flexible side walls supported by a rigid frame, is coupled to a variable volume chamber via a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.
