Abstract: A follower for a window accessory within an insulated glass assembly. The follower includes a body having first and second sides adapted to face first and second spaced glazing panels. The follower further includes at least one magnet within each of the two sides, so that the follower will couple with a magnetic operator placed on either of the glazing panels. The follower yet further includes wheels having a diameter larger than the width of the body to rotatably support the follower against either of the glazing panels.

Abstract: A valve activating system is provided, which is intended for association with a valve assembly including a valve housing defining a conduit therein which includes a fluid inlet opening and a fluid outlet opening, and a valve which is normally biased in a closed position in the conduit to control the flow of fluids therethrough. In order to activate the valve an opening is provided into the conduit for insertion of a valve activating element, such as a simple lever which is positioned at a location at which it can activate the valve. In the embodiment shown, the opening into the conduit has a circular cross-section and is fitted with a sealing O-ring. The lever is sized and shaped so that its insertion through the O-ring will complete a fluid tight closure of the opening so that fluid present in or flowing through the conduit cannot exit through the opening provided for the lever. Therefore the valve activating system remains dry.
