Abstract: A computer-implemented method for placing insurance coverage with insurers includes a broker user interface, and an insurer user interface for displaying a graphical representation of an insurance tower. The insurer user interface provides one or more insurers the ability to select, bid or request variants of the insurance tower. A blockchain system is used for authorizing one or more bids or variants in the insurance risk towers.

Abstract: An inkjet printhead having a housing having a top face and a bottom face, an ink ejection device and a contact circuit. The contact circuit is affixed to the housing in a substantially horizontal orientation and is in communication with the ink ejection device. The contact circuit is configured to connect the ink ejection device to an external device.

Abstract: Some embodiments of the present invention provide an inkjet printhead within which a removable ink cartridge can be installed. Upon installation, the ink cartridge can be coupled to one or more wicks in the printhead for establishing fluid communication between one or more chambers in the ink cartridge and nozzles through which ink exits the printhead during operation. The wick can extend from a cartridge receptacle to a substantially enclosed ink reservoir in order to transport ink from the removable cartridge to the ink reservoir.

Abstract: This invention relates to a check valve (19) for use in an ink supply line (13) of an ink jet printing system (1) between an ink reservoir (11) and an inkjet printhead (3) so as to prevent de-priming of the printhead upon the latter being subjected to impact loads or the like. Specifically, the improvement of this invention comprises a one-piece check valve (37) of an elastomeric material having a flapper valve (43) movable between a closed position in which the flapper valve blocks the backflow of ink and an open position in which ink is free to flow past the check valve member to the printhead. The flapper valve (43) is defined by a slot (49) separating the flapper valve from the outer margin (41) of the check valve (37) and the flapper valve is integrally joined to the outer margin by a hinge portion (45) so as to enable movement of the flapper valve between its open and closed positions.

Abstract: This invention relates to a replaceable ink container or bottle (1) for an ink jet printing apparatus in which the mouth of the bottled is closed by a puncturable diaphragm (19). A puncturing member (35) carried by the ink reservoir (21) of the ink jet printing apparatus pierces through the diaphragm upon the container being installed in the ink jet printing apparatus. Upon the puncturing member (35) puncturing through the diaphragm (19), the diaphragm sealingly engages the sides of the puncturing tube so as to substantially prevent the ink from leaking therepast, and the puncturing tube opens communication between the ink within the container and the ink reservoir thereby permitting ink to flow from the bottle into the ink reservoir via the puncturing member.

Abstract: An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming.

Abstract: An ink jet printer cartridge assembly including a cartridge body with at least one ink chamber from which ink flows to a print head. A standpipe in the ink chamber includes an opening therethrough for the flow of ink to the print head, and a filter cap is secured on the top of the standpipe to limit the introduction of air bubbles and particulate matter in the flow of ink toward the print head. The filter cap includes a mesh material formed into a dome-shaped configuration and an elastomeric material molded about the periphery of the mesh portion, with the elastomeric material being received around the top portion of the standpipe.
