Abstract: Apparatus for continuous ink jet printing, comprising: an ink system comprising an ink storage tank (15) operable to supply ink to a print head associated with the apparatus; a single cartridge connection (9) for releasable engagement with a fluid cartridge (8), the cartridge connection (9) comprising: a fluid connector (10) for engaging an outlet of a fluid cartridge; and a conduit configured to allow fluid to flow along a fluid pathway from a cartridge engaged with the cartridge connection, via the fluid connector, to the ink storage tank. The apparatus has a first configuration in which a solvent cartridge is engaged with the cartridge connection and in which the apparatus is configured to receive solvent from the engaged solvent cartridge, and a second configuration in which an ink cartridge is engaged with the cartridge connection and in which the apparatus is configured to receive ink from the engaged ink cartridge.

Abstract: A heat exchanger includes a shell, refrigerant distributor, tube bundle, and a first baffle. The shell has a refrigerant inlet through which at least refrigerant with liquid refrigerant flows and a shell refrigerant vapor outlet. A longitudinal center axis of the shell extends substantially parallel to a horizontal plane. The refrigerant distributor fluidly communicates with the refrigerant inlet and is disposed within the shell. The refrigerant distributor has at least one liquid refrigerant distribution opening that distributes liquid refrigerant. The tube bundle is disposed inside of the shell below the refrigerant distributor. The first baffle extends from a first lateral side of the shell. The first baffle is vertically disposed 5% to 40% of an overall height of the shell above a bottom edge of the shell, and extends laterally inwardly from the first lateral side by a distance not more than 20% of a width of the shell.

Abstract: A method of driving an electromechanical converter of a print head of a continuous inkjet printer, wherein the electromechanical converter is arranged to break up a continuous stream of ink into a plurality of drops. The method includes determining a modulation voltage to drive the electromechanical converter, at least a property of the modulation voltage being controlled to take into account movement of a break up point of the continuous stream of ink, and to ensure that in a characteristic of modulation voltage versus a property at least indicative of a break up point of the continuous stream of ink, the characteristic has a predetermined gradient, or a gradient related to this predetermined gradient; and driving the electromechanical converter at the determined modulation voltage.

Abstract: The present invention relates to ink jet printing. More particularly, the invention relates to a condenser assembly for an ink jet printer. The condenser assembly comprises a first condenser adapted to separate first solvent vapor from a first fluid by condensation of said first solvent onto a first coolable surface and a second condenser adapted to separate second solvent vapor from a second fluid by condensation of said second solvent onto a second coolable surface.

Abstract: A continuous ink jet printer comprises a gutter for collecting ink droplets not used in printing. Pumping apparatus draws ink from the gutter and control apparatus is configured to vary the level of pumping by the pumping apparatus depending on the temperature or other parameter of the ink. As the temperature of the ink increases the level of pumping is reduced. The pumping apparatus may comprise two venturi pumps connected in parallel each having its throat connected to the gutter.

Abstract: A method is provided for simulating customer reaction to stimulus based on historical observable customer outcomes. Embodiments of the invention describe a series of steps that when taken together accomplish a predictive outcome of customer simulation from a plurality of source inputs without prior assumptions of relationship between inputs and simulated outcomes. The invention comprises a series of steps that effect the framing of the simulation model from which customer predicted outcomes are made. The various frames required to create the preferred simulation model include: customer database development, stimulus archetype development, model data development, model building, simulation of future customer reaction and suggested courses of action based on the results of the simulation.

Abstract: Methods and systems described herein may represent organizations as a network, where the network nodes and links may be displayed, analyzed, and structured. The network nodes may represent positions within an organization, with network links established based on reporting relationships between such positions in the organization. A position may be filled by a person/entity, may stand for an organizational unit, may represent a leadership team, and/or may be associated with a location. In addition to position, other node types may include organizational unit, person, group, and/or place. Organization networks structured by these node types may thus have associated node modes, as in the position example. Other node types may also be used in the representation of organization. The network representation may provide network metrics for the organization, including level (the path length, or number of links, to the root node), size (the number of nodes), and span (the number of reporting relationships to each node).

Abstract: A method and system for performing retail transactions allows use of a wireless device in lieu of conventional financial cards. A retail system sends customer-independent transaction data, which is matched with a customer account associated with a wireless device. A customer sends a wireless communication from a wireless device to a server. The server identifies the wireless device and identifies a customer account associated with the wireless device. The customer account and the customer-independent transaction data are matched together, authorizing the retail transaction. When multiple retail transactions occur within a short time, a matching technique scores matches between multiple retail transactions and multiple customer-initiated wireless communications.
