  • Patent number: 8236240
    Abstract: The invention provides a method and system for conducting a continuous operation, flowing vapor phase decontamination in either an open loop or a closed loop. Using the method, a multi-component liquid decontaminant is vaporized and delivered into, through and out of a sealable enclosure by means of a carrier gas that is flowing into, through and out of said sealable enclosure. After leaving the enclosure, the vapor is captured in a cold-water bath and decomposed. The invention humidifies the carrier gas by passing it through a temperature controlled water bath to warm, or to cool, the carrier gas as necessary in order to bring the carrier gas to the desired temperature and humidity before it is combined with the vaporized sterilant and allowed to flow into the sealable enclosure. The concentration of the vapor sterilant and the percent saturation of the vapor sterilant are simultaneously controlled by controlling the rate at which the carrier gas flows and the rate at which the liquid sterilant is vaporized.

  • Publication number: 20120132723
    Abstract: An apparatus for atomizing a precursor liquid for vapor generation and thin film deposition on a substrate. The precursor liquid is atomized by a carrier gas to form a droplet aerosol comprised of small precursor liquid droplets suspended in the carrier gas. The droplet aerosol is then heated to form vapor, producing a gas/vapor mixture that can be introduced into a deposition chamber to form thin films on a substrate. The liquid is introduced into the atomizing apparatus in such a manner as to avoid excessive heating that can occur or lead to the formation of undesirable by-products due to material degradation as result of thermal decomposition. The apparatus is particularly suited for vaporizing high molecular weight substances with a low vapor pressure that requires a high vaporization temperature for the liquid to vaporize. The apparatus can also be used to vaporize solid precursors dissolved in a solvent for vaporization.

  • Patent number: 8165460
    Abstract: An apparatus for generating an aerosol of a therapeutic agent and methods of using the same are disclosed. The apparatus comprises a heating element having a surface and a composition coating at least a portion of the heating element surface. The composition comprises a carrier and a therapeutic agent, wherein when the heating element surface is heated to at least the vaporization point of the carrier, the carrier vaporizes and releases the therapeutic agent from the composition as an aerosol. The heating element can be a coiled filament. The therapeutic agent can be a small molecule, a polynucleotide, a polypeptide, or a recombinant virus. The apparatus can be incorporated into a delivery device, such as a metered dose inhaler or an exposure chamber.

  • Patent number: 7905240
    Abstract: A device and a method for preventing the drying of fluid products in a delivery head of a machine for dispensing fluid products, wherein the delivery head is provided with a plurality of delivery nozzles. The device comprises first elements to generate a conditioning flow, second elements to convey the conditioning flow towards a space underneath the delivery nozzles and create in said space an atmosphere different from that of the environment in which the dispensing machine is to be found during use. The delivery nozzles are divided into at least two groups and the space is divided into at least two distinct conditioning zones, disposed in correspondence with the groups of delivery nozzles. Different atmospheres are created in the conditioning zones, according to the type of fluid product delivered by the corresponding group of delivery nozzles.

  • Patent number: 7766254
    Abstract: A heated fuel injector includes a heated body, liquid fuel flowing through a fuel passage within the body, and a member that increases heat transfer from the heated body to the fuel within the fuel passage. The thermal efficiency of the fuel injector is increased separately or in combination by diverting the fuel flow along an inner circumferential contour of the heated body, by limiting the volume of fuel bypassing the heated inner surface of the body, by redirecting heat from the body to unheated portions of the fuel flow field within the fuel passage, and by increasing the available contact surface area for heat transfer. Improved heat transfer from the heated body to the fuel is achieved by integrating features that increase the contact surface area into the inside surface of the body or by positioning an insulating or a thermally conductive spacer within the fuel passage.
