Abstract:
In one example, a land based seismic sensing device includes: a seismic sensing unit having a seismic sensor in a housing configured to be buried in the ground; a control unit including a battery in a weather resistant housing configured to be exposed above ground; and a flexible cable mechanically and electrically connecting the seismic sensing unit and the control unit. The cable includes a weather resistant jacket and an electrically conductive element inside the jacket detachably connected between electronic circuitry in the sensing unit and electronic circuitry in the control unit. In one example, the control unit housing includes a first compartment configured to stow the seismic sensing unit and a second compartment configured to stow the cable.
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. Upon installation the sealing member is engaged and displaced from the first position to the second position such that the sealing surface engages against a structure of the fluid inlet to create an ink seal.
Abstract:
An apparatus and method for removing air or other gases from a free-ink ink-jet pen is provided in a manner that does not waste ink or require disposal of purged ink. A gas separation and purge mechanism is incorporated into a pen body construct having an ink containment chamber such that gases will rise toward the mechanism. A vacuum is cyclically applied to the gas separation and purge mechanism to remove the gas and to allow the ink containment chamber to refill from a remote reservoir as needed.
Abstract:
The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system is of the type having a receiving station for receiving the replaceable ink container. The receiving station has a fluid inlet and a sealing structure. The replaceable ink container includes a reservoir defining a fluid outlet and a sealing surface proximate the fluid outlet. The replaceable ink container also includes a sealing material contained within the reservoir for wetting the sealing surface to seal defects between the sealing surface and the sealing structure.
Abstract:
A modular ink jet ink delivery system comprising a print manifold including a passageway therethrough for the transfer of ink and a pen tower removably and operatively engageable with the manifold. The pen tower includes a central passageway for receiving and transferring ink from the manifold. A retainer member is operatively connected to the manifold. A first sealing member forms a first seal with the retainer member. A second sealing member forms a second seal with the pen tower such that when the pen tower and the manifold are operatively engaged with each other, a substantially sealed passageway is formed for the transfer of ink from the manifold to the pen tower.
Abstract:
The present disclosure relates to an inkjet printing system configured for receiving a replaceable ink container. The replaceable ink container has an ink extraction characteristic that varies with ink level in the replaceable ink container. The inkjet printing system includes an ink level determining device for determining ink level within the replaceable ink container. Also included is a control device for selecting a print mode based on ink extraction characteristics of the replaceable ink container.
Abstract:
A pump having a rotary portion which compels the movement of a fluid by peristaltic compression of resilient tubing containing the fluid includes a roller assembly having at least one roller mounted in the rotary portion of the pump for contact with the resilient tubing. The roller has a range of rotation in contact with the tubing during pump operation. A roller control mechanism is adapted and constructed to stop the roller at a single, predetermined location on the tubing when the pump operation is stopped.
