  • Publication number: 20150139855
    Abstract: An incubator includes filters in supply passages for supplying an environment-adjusting-medium. Divergent passages are connected to portions of the supply passages upstream from the filters. The divergent passages converge to a single supply/exhaust passage, which is provided with a pump. By driving the pump in a forward or reverse direction, decontamination gas is pumped from a culture space and discharged outside, and open air is introduced into the culture space. After sucking the contamination gas to adsorb it on the filter, open air is introduced so that the contamination gas is discharged into the culture space 6.

  • Patent number: 9028750
    Abstract: Fumigation systems and processes that are especially applicable for the fumigation of perishable (or otherwise sensitive to temperature) agricultural products as the temperature conditions under which the product is being treated are closely controlled to advantageously prevent the product from being exposed to temperature drops and/or spikes during the fumigation cycle. In addition, the present invention incorporates an air filtration system as a part of the fumigation system to substantially remove the toxic fumigant residuals from the air before it is exhausted into the open atmosphere, which typically occurs at the completion of a fumigation cycle. As such, the harmful effect of the fumigant on the products and the surrounding environment and work areas is greatly minimized. In summary, the systems and processes of the present invention provide the ability to conduct fumigations in a well-controlled environment.

  • Patent number: 9017607
    Abstract: A system for decontaminating a medical device includes a decontamination chamber configured to retain the medical device and a chemical dispersion assembly configured to deliver a decontaminating fluid to the decontamination chamber. A pressure control assembly is connected to the decontamination chamber and configured to control the pressure in the decontamination chamber. The system also includes a system controller configured to control the decontamination chamber, chemical dispersion assembly, and pressure control assembly. A pressure in the decontamination chamber is reduced to within a sub-atmospheric pressure range in a first evacuation step and add a decontaminating fluid into the decontamination chamber at a first rate while increasing the pressure in the decontamination chamber. Adding the decontaminating fluid increases a relative humidity in the decontamination chamber to a level that improves the efficacy of the decontaminating fluid.

  • Patent number: 7850906
    Abstract: An apparatus for sterilizing a sealable enclosure includes a circuit for flow of a sterilizing gas or gasses. The circuit is connected to the enclosure to be sterilized to form a closed circuit and pumps to circulate gas through the circuit and enclosure. The circuit has parallel branches one of which contains apparatus to deactivate a sterilant to be added to the carrier gas flowing through the circuit and apparatus to dehumidify the gas. The other branch contains apparatus to heat the gas and apparatus to supply a sterilant vapor or vapors to the gas. Control apparatus determines which of the parallel branches the gas flows through. The control apparatus maintains flow through one branch passage until the relative humidity falls below a predetermined level. The flow through that branch is then terminated and flow through the other branch initiated.

  • Publication number: 20100143189
    Abstract: The disclosure relates to an apparatus (10) for decontaminating an enclosure that includes a passage having an inlet (18) to receive a carrier gas from the enclosure, an outlet (31) to discharge the carrier gas to the enclosure, a fan (21) for causing a low of carrier gas through the passage from the inlet to the outlet, and a vapour generator (19) where a decontaminant vapour is introduced into the flow of carrier gas to be discharged with the flow at the outlet to decontaminate the enclosed space. A further fan (33) delivers a separate flow of gas from the enclosure bypassing the passageway in which the decontaminant vapour is introduced to be delivered into the enclosure from outlet vents (32) adjacent the vapour outlets (31) to assist in dispersing the carrier gas containing decontaminant vapour throughout the enclosure.

  • Patent number: 7699906
    Abstract: The present invention relates to iodinated resins. It relates in particular to a process for preparing a polyiodide-resin wherein an anion exchange resin is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The absorbable member is selected from the group consisting of I.sub.2 and polyiodide ion having a valence of ?1. In the process, conversion of the anion exchange resin to the polyiodide-resin is effected at elevated temperate and/or elevated pressure, the elevated temperature being about 100.degree. C. or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to a substance comprising an iodine (impregnated) resin as produced by the above process.

  • Patent number: 7682560
    Abstract: As shown in FIG. 1 there is one embodiment of a fumigation apparatus in the form of a module (8) including a panel (10) which can be positioned in or at an opening of an enclosed space in use to define a fumigation chamber. Fumigant inlet means in the form of an orifice (12) are arranged in the panel (10) to allow a flow of a fumigant directly into the fumigation chamber. A nominal number of mixing fans, in this case two fans (16) and (18), thoroughly circulate gases within the fumigation chamber when operating. The module (8) includes a system control box (14) linked to the fumigant delivery orifice (12) and valve system which functions to control the flow of toxic gas into the fumigation chamber. The panel (10), when positioned in use, is secure against the passage of fumigant and gases by means of an inflatable rubber seal (22) which is located around a lip edge perimeter of the panel (10).
