ABSTRACT:
An appliance comprising a unitary, atmospheric pressure, equalization chamber and drying chamber in the form of a sealed, flexible walled container is provided with means communicating from its interior to the space between a double glazed window. A separable coupling between the container and the space permits replacement of the appliance when its drying capability is exhausted. Window frame contructions unobtrusively incorporate the appliance in a cavity which has a removable cover. Variations in atmospheric pressure are balanced within the space between the window lights by changes in the atmospheric pressure on the flexible walled container while such changes transfer gas between the space and the container to expose it to the desiccant. One separable coupling passing the gas is a hollow needle inserted through a resilient, self-sealing, passage which can be integral with a seal gasket between the lights.
