    摘要： There is disclosed herein a refrigerant container in the form of a bag, or pouch, made from two sheets of multi-layer barrier film material which are heat sealed adjacent their edges to form a closed pouch which has an interior space. The bag may be connected to an access valve provided in a line of a sealed refrigeration system for capturing the refrigerant therefrom. The barrier film material is specially formulated to prevent outward permeation of a refrigerant and to prevent inward permeation of air. A valve stem is provided for filling and emptying the bag.

    摘要： A getter system is provided for use with an evacuated container such as a vacuum insulation panel. The getter system has a first, activated getter material capable of gettering at least a first gas or vapor and a second, different gas or vapor. The getter system also has a second, activated getter material capable of gettering the first, but not the second, gas or vapor. Finally, the getter system includes packaging for the first and second getter materials, such that the first and second getter materials may be placed together within a single compartment of the evacuated container and the second getter material will be more readily exposed to the first gas or vapor than the first getter material. In this manner, the first getter material will be protected from the first gas or vapor even though it is already activated.

    摘要： A getter structure is provided which can be handled for relatively short periods of time in open atmosphere and yet provides prolonged gettering action over relatively long periods of time when utilized in a sealed compartment. The getter structure has a thin flexible substrate upon which a getter material is applied. A barrier layer is applied to the getter material to prevent rapid reaction by the getter material with the atmosphere. The substrate or barrier layer is semi-permeable and is selected to provide the desired degree of permeation of the layer to the getter material to result in the action described. Such a getter structure is useful in a vacuum insulation panel, particularly in a getter system in a multiple compartment panel where different getter materials are utilized in different compartments so as to maximize the effectiveness of the use of the getter materials, while minimizing the cost of the getter materials required to provide the desired degree of gas gettering.

    摘要： A vacuum insulation panel having flexible gas impermeable walls formed in multiple substantially adjacent compartments. A thermal break may advantageously be provided around the perimeter to prevent conduction of heat from a warmer side of the panel to a colder side, which thermal break can be easily constructed by utilizing webs of gas impermeable material with the foil carried thereon such that the foil has a width somewhat less than the width of the film and with two separate pieces of the firm rotated at 90.degree. to one another to provide a continuous area void of the foil.Multiple compartments are utilized to enhance the long term thermal characteristics of the panel by "protecting" the vacuum characteristics of at least one of the compartments by surrounding it with additional evacuated compartments. This results in a very minimal gas pressure gradient across the internal walls forming the internal compartment to minimize gas and vapor permeation into it thus greatly enhancing the lifetime of the panel. Further, this permits strategic placing of gettering materials such that gettering materials absorbing certain gases can be placed in the outer compartments and other gettering materials absorbing different gases can be placed in the internal compartments to enhance the lifetime of the panel.

    摘要： A method for assembling a vacuum insulation panel is provided which includes the steps of: loading a quantity of microporous powder into a gas permeable pouch; pressing the pouch into a desired form; sealing the pouch; heating the powder to a temperature elevated above standard room temperature; inserting the pouch into a gas impermeable bag while the pouch and powder remain at the elevated temperature; evacuating gases from the powder pouch while it is at the elevated temperature; evacuating gases from the bag; and sealing the gas evacuated bag with the gas evacuated pouch therein to form a vacuum insulation panel. The heating of the powder may occur only just before insertion of the pouch into the bag, or may occur both before the powder is loaded into the pouch as well as just before insertion of the pouch into the bag. Further, a trace amount of Helium (at a pressure of approximately 1 mm Hg) may be put into the bag before it is sealed in order to permit testing of the sealed panel for leaks.

    摘要： A method of verifying the integrity of the walls and seals of a sealed container is provided in which a low molecular weight gas is introduced into the interior of the container before the container is sealed. After sealing, the container either alone, or in batches with others, is placed into a chamber which is evacuated of gases to a pressure level below that interior of the container and is evacuated of the low molecular weight gas to a partial pressure below that which the gas has within the container. Subsequently the gas within the chamber is sensed to determine whether the rate of increase of the low molecular weight gas in the chamber exceeds a predetermined rate.
