  • Patent number: 10328691
    Abstract: A print head has a jet stack, a jet stack heating and temperature measuring element thermally connected to the jet stack, the jet stack heating and temperature measuring element including: a first, etched copper layer having heat spreading characteristics and including a resistive heat source electrically connected in series to a voltage source and a switch; an electrically insulative on a back side of the first copper layer; and a second, etched copper layer on a side of the electrically insulative layer opposite the first copper layer, the second copper layer having a temperature sensing element to sense a temperature of the print head without a thermistor, the temperature sensing element connected in series with a voltage source and a transistor. A print head may use a thermistor but the heat spreading layer eliminates the need for a heat sink to attach to the print head.

  • Patent number: 9931840
    Abstract: Print head jet stack heating and temperature measurement systems and methods are disclosed that both heat the jet stack and determine a temperature of the jet stack. The heating and temperature determination are performed by a flex circuit that includes multiple layers. One of the layers heats the jet stack and another one of the layers provides data that determines the temperature of the jet stack. The heating layer and the temperature sensing layer are separated by an insulative material in the flex circuit. The temperature of the jet stack can be sent to a print head controller that then determines whether to increase or decrease the temperature of the jet stack.

In particular the vaccines and immunogenic compositions of the present invention relate to flagellin-antigen fusion proteins in which the spatial orientation of the flagellin to antigen and the charge distribution of the antigen is optimized to enhance immunogenicity and/or reduce reactogenicity. The present invention also relates to methods of evaluating the vaccines by measuring the relative expression of certain gene markers. Altered expression of the genes relative to flagellin control sample may indicate that the vaccine is suitable to stimulate an adaptive immune response to the antigen component in the subject with minimal side effects.

  • Patent number: 8454144
    Abstract: A reservoir is provided for a printhead in an ink jet printing machine, the printhead having at least one printhead inlet at a rear face thereof for flow of ink from the reservoir into the printhead. The reservoir comprises a perimeter wall sealably mounted to the rear face of the printhead and defining a chamber in communication with the printhead inlet. The chamber is open at one face and the reservoir includes a resilient flexible membrane attached to the perimeter wall and covering the one face. An inlet is provided in communication with the chamber for passage of ink into the chamber. The resilient flexible membrane has an initial relaxed condition in a first state in which the reservoir is substantially full of ink, and a flexed condition in which the membrane is collapsed into the chamber.
