Claim 7

Dependent Claim 64 words

A window according to claim 5, including roller means mounted rotatably within said upper and lower compartments, said sheet material having a width less than said slots and an area which is substantially equal to that of said second pane carried by said rollers for movement through said slots in threaded manner, said sheet material being formed of a solar heat ray absorbent material.

Claim 8

Dependent Claim 28 words

A window according to claim 6, wherein said sheet is connected at its opposed horizontal edges to at least two string-like elements to thereby form a closed loop.

Claim 9

Dependent Claim 27 words

A window according to claim 7, wherein said string-like elements are positioned laterally along said sheet so as not to be visible when viewing through said panes.

Claim 10

Dependent Claim 83 words

A window according to claim 7, including a bracket member positioned within said upper compartment for supporting each end of the roller means therein in vertically guided fashion, each said bracket member thus being provided with a vertical slot, the ends of said roller means being slidable within said slots, spring means being secured within said upper compartment adjacent each said bracket member cooperable with the respective ends of said roller means for biasing same to maintain predetermined longitudinal tension on said loop.

Claim 11

Dependent Claim 22 words

A window according to claim 7, including transversely extending stiffening means for said string-like elements to prevent longitudinal bowing of the loop.

Claim 12

Dependent Claim 50 words

A window according to claim 6, including a gear wheel carried by said lower roller means, a drive motor, a flexible cable drivable by said motor having a worm gear at the end thereof remote from the motor and cooperable with said wheel gear for driving the lower roller means.

Claim 13

Dependent Claim 34 words

A window according to claim 6, wherein said second frame hermetically seals said pane mounting frame and an inert gas is maintained within the system comprising said compartments and the regions between said panes.

Claim 14

Dependent Claim 66 words

A window according to claim 7, including transverse stiffening elements carried by said sheet at the opposed horizontal end portions thereof, said string-like elements being secured to attachment members which are in turn secured to said stiffening elements, sensor switch means being provided cooperable with said attachment members and adapted to generate a signal when said sheet is not in correct disposition relative to said panes.

Claim 15

Dependent Claim 188 words

An all season window comprising: a peripherally extending pane mounting frame mounting said window in an exterior wall of a structure having an interior space; first, second and third panes of essentially rigid transparent sheet material mounted sealingly and fixedly within said frame in spaced parallel relationship each to the other, said second pane being interposed between said first and third panes; a discrete amount of solar heat ray absorbent material maintained either at a first location between said first and second panes to provide insulation from solar heat of said interior space or at a second location between said second and third panes to provide solar heat to said interior, said discrete amount being sufficient to substantially fill only one of said locations at a time; and means for selectively moving said solar heat ray absorbent material between said first and second locations; said solar heat ray absorbent material comprising a liquid; said means for moving said solar heat absorbent material comprises a pump, motor means, a first conduit connecting said first location to said pump and a second conduit connecting said second location to said pump.

Claim 16

Dependent Claim 188 words

An all season window comprising: a peripherally extending pane mounting frame mounting said window in an exterior wall of a structure having an interior space; first, second and third panes of essentially rigid transparent sheet material mounted sealingly and fixedly within said frame in spaced parallel relationship each to the other, said second pane being interposed between said first and third panes; a discrete amount of solar heat ray absorbent material maintained either at a first location between said first and second panes to provide insulation from solar heat of said interior space or at a second location between said second and third panes to provide solar heat to said interior, said discrete amount being sufficient to substantially fill only one of said locations at a time; and means for selectively moving said solar heat ray absorbent material between said first and second locations; said solar heat ray absorbent material comprising a liquid; said means for moving said solar heat absorbent material comprises a pump, motor means, a first conduit connecting said first location to said pump and a second conduit connecting said second location to said pump.

Claim 17

Dependent Claim 97 words

Claim 18

Dependent Claim 53 words

A window according to claim 15, including a limit switch having sensors operably associated with said second set of conduits and with said motor means for deactivation of the motor means upon the pumping of said solar heat ray absorbent material to a predetermined level within one of the regions between said panes.
