Apparatus for shaping at least one glass sheet wherein a lower press ring and an upper press ring are configured to clamp a perimeter section of the glass sheet between the lower press ring and the upper press ring. The apparatus also includes an upper press at least partially disposed within the upper press ring and configured to shape at least a section of the glass sheet inside the perimeter section of the glass sheet, including forming by use of applied vacuum. The inner press may include openings that apply vacuum in selected areas of the inner press to vacuum form the ply within the selected areas. To control the ply on the upper press assembly, vacuum that is applied though passageways in the upper press ring to the gap between the upper press ring and the inner press is controlled through a seal in the gap. The upper press ring includes pivotal joints that increase adjustability of the forming surface of the upper press ring to the face surface of the inner press.

Multi-stage glass pressing systems and methods

Apparatus for shaping at least one glass sheet wherein a lower press ring and an upper press ring are configured to clamp a perimeter section of the glass sheet between the lower press ring and the upper press ring. The apparatus also includes an inner press at least partially disposed within the upper press ring and configured to shape at least a section of the glass sheet inside the perimeter section of the glass sheet. The inner press is fixed to a top plate and is moveable within limits with respect to the upper press ring. When a suspension assembly and the top plate are lowered, a carrying frame limits the descending movement of the upper press ring so that the inner press descends under gravity force until the upper press ring contacts the carrying frame and the suspension assembly decouples from the top plate. The inner press continues to move downwardly under gravity force to shape the center part of the ply until the top plate contacts the upper press ring. To unclamp the ply, the suspension assembly is vertically raised to cause the suspension assembly to re-couple with the top plate and move the inner press upwardly until the suspension assembly lifts the upper press ring together with the inner press.

Two-stage gravity press

The present invention provides a connector assembly for electrically connecting to an electroconductive element having an electroconductive connector with a generally flat pad portion, a terminal portion capable of connecting the assembly to an external device and connecting portion interconnecting the pad and terminal portions, and a preformed plug member sized to a predetermined configuration and overlaying the pad portion such that a major surface of said pad portion is exposed along a first surface of the plug member. The exposed surface may be covered with an adhesive and in one embodiment of the invention, the connecting portion extends through the plug member. The plug member is preferably an electrically nonconductive and moisture impervious material.
