An apparatus, such as a window in a frame which is mounted in a casing and that can be pivoted 180째 within the casing for use on both faces. A pair of concealed hinges mounted, between the casing and the frame, provide pivots about which the frame is rotated. Further, a connector is mounted on opposing faces of the frame. An opening and closing device can be alternately connected and disconnected between the casing and opposing connecters. When disconnected, the frame is rotatable. Once rotated, the opening and closing device is reconnected to the connector on the opposite face of the window. Deformable sealing elements are mounted around the periphery of the frame and on either side of the concealed hinges to provide an air tight seal when the frame is closed.

What is claimed is: 1. A system engaged with and pivotally supporting a frame having opposing faces, the frame being mounted on a casing, the system engaging either one face or an opposing face, the system comprising: a pivot located between the casing and the frame at opposing positions along an axis which passes through the center of the frame for rotating the frame thereabout from 0-180 degrees; deformable sealing elements positioned about a periphery of the frame and attached to one of either the casing or the frame for sealing between the casing and the frame; connectors located on opposing faces of the frame and on opposing sides of the pivot to permit the frame to be alternately connected to the casing by the one face of the frame or by the opposing face of the frame; and an opening and closing device, alternately connectable between the casing and the connector on the one face and the connector on the opposing face of the frame so that, when connected, the opening and closing device can be actuated to open and close the frame relative to the casing, and when not connected, the frame can be rotated about the pivot to permit pivoting 180째. 2. The system as described in claim 1 wherein the pivot is a pivot bolt held in a concealed hinge, the hinge further comprising: a first mounting plate; a second mounting plate having a socket; a pivot bolt plate positioned adjacent the first mounting plate, the pivot bolt being connected to the pivot bolt plate and extending through a pivot hole in the first mounting plate, wherein the pivot bolt further extends to the second mounting plate for engaging the socket therein for pivotally connecting between the casing and the frame permitting the frame to rotate about the pivot bolt. 3. The system as described in claim 2 wherein the pivot bolt plate is adjustable relative to the first mounting plate for extending the pivot bolt therethrough so as to alternately release and engage the pivot bolt with the second mounting plate. 4. The system as described in claim 3 wherein the pivot bolt plate and first mounting plate are mounted in the casing and the second mounting plate is mounted in the frame. 5. The system as described in claim 2 wherein the pivot bolt plate and first mounting plate are mounted in the casing and the second mounting plate is mounted in the frame. 6. The system as described in claim 2 wherein the concealed hinge further comprises a friction element acting between the pivot bolt and the pivot bolt plate for altering the friction acting on the pivot bolt to resist free rotation of the frame about the pivot bolt. 7. The system as described in claim 2 wherein the pivot bolt is a double screw further comprising: an adjusting nut threaded at a first end; a locking nut threaded at a second end; and a friction element comprising a plurality of friction discs and a spring positioned therebetween, the adjusting nut being rotated to alter friction acting on the pivot bolt. 8. The system as described in claim 1 further comprising deformable sealing elements adjacent either side of the pivot. 9. The system as described in claim 8 wherein the deformable sealing elements are sized slightly larger than the space between the casing and the frame so as to cause the deformable sealing elements to deform and seal therebetween. 10. The system as described in claim 1 wherein the deformable sealing elements are sized slightly larger than the space between the casing and the frame so as to cause the deformable sealing elements to deform and seal therebetween. 11. The system as described in claim 1 wherein the concealed hinge further comprises a friction element acting on the pivot bolt for altering the friction to resist free rotation of the frame about the pivot bolt. 12. The system as described in claim 1 wherein the opening and closing device further comprises: a block fixed to the casing adjacent the location of the connector, the block having a guide pin extending therefrom; and an arm removably connected to the connector on the frame and having a sliding track formed thereon for engaging the guide pin attached to the block so as to permit movement of the guide pin therein for positioning or locking the position of the frame. 13. The system as described in claim 12 wherein the sliding track is sized so as to retain the guide pin for movement therein and further comprises a plurality of enlarged track areas for positioning the pin to lock the frame at a variety of angles within the casing. 14. The system as described in claim 12 wherein the arm is connected to the connector using a bracket. 15. The system as described in claim 12 wherein the sliding track has a release opening for engaging and disengaging the guide pin therein. 16. The system as described in claim 1 wherein the connector further comprising: a fixed mounting plate attached to the frame adjacent the block; a sliding rod; and a locking plate removably attached to the fixed mounting plate for sandwiching the sliding rod therebetween; wherein the arm is removably attached to the sliding rod by the bracket for connection to the frame. 17. The system as described in claim 16 wherein the bracket has a tubular channel formed thereon through which the sliding rod is installed. 18. A system engaged with and pivotally supporting a frame having opposing faces, the frame being mounted on a casing, the system engaging either one face or an opposing face, the system comprising: a pivot located between the casing and the frame at opposing positions along an axis which passes through the center of the frame for rotating the frame thereabout from 0-180 degrees; deformable sealing elements positioned about a periphery of the frame and attached to one of either the casing or the frame for sealing between the casing and the frame; and connectors located on opposing faces of the frame and on opposing sides of the pivot to permit the frame to be alternately connected to the casing by the one face of the frame or by the opposing face of the frame; wherein the pivot is a pivot bolt held in a concealed hinge, the hinge further comprising; a first mounting plate; a second mounting plate having a socket; a pivot bolt plate positioned adjacent the first mounting plate, the pivot bolt being connected to the pivot bolt plate and extending through a pivot hole in the first mounting plate, wherein the pivot bolt further extends to the second mounting plate for engaging the socket therein for pivotally connecting between the casing and the frame permitting the frame to rotate about the pivot bolt, wherein the concealed hinge further comprises a friction element acting between the pivot bolt and the pivot bolt plate for altering the friction acting on the pivot bolt to resist free rotation of the frame about the pivot bolt and wherein the friction element comprises a plurality of discs positioned in a housing between the pivot bolt and the pivot bolt plate, the discs biased so as to urge the pivot bolt away from the pivot bolt plate. 19. The system as described in claim 18 wherein the friction discs are biased by a spring. 20. The system as described in claim 18, further comprising an opening and closing device, alternately connectable between the casing and a connector on the one face and the connector on the opposing face of the frame so that, when connected, the opening and closing device can be actuated to open and close the frame relative to the casing, and when not connected, the frame can be rotated about the pivot to permit pivoting 180째.
