A single axis application unit for processing a glass workpiece includes a workpiece supporting table, an applicator movable on a traveler shiftable along a first linear axis and a central suction unit that is activateable to grip the glass workpiece that travels along a second linear axis oriented generally perpendicular to the first linear axis. A central suction unit brake selectively secures the central suction unit both rotationally and translationally. The central suction unit is freely moveable both translationally and rotationally when the central suction unit brake is released. A mid-peripheral suction unit is located at a fixed location remote from the central suction unit and selectively activateable to grip the glass workpiece to hold the glass workpiece in a fixed orientation. A corner suction gripper is movable with the applicator parallel to the first linear axis, and is selectively activateable to grip the glass workpiece.

A window glazing assembly that can convert an existing or already-installed window, or be used to assemble new construction windows as a multi-pane or multi-glazed window unit, is provided herein. In particular, the glazing assembly includes an attachment assembly (e.g., peel-and-stick double-sided adhesive tape) and one or more glazing layers. Some embodiments further include a spacer assembly comprising a plurality of spacer bars that may be individually installed, e.g., one by one, around the perimeter of the window such as, to the window sash, window frame, or glass window pane, itself. The glazing layer(s) can then be secured or adhered to the spacer assembly, for example, around the perimeter thereof. Some embodiments may include additional or intermediate glazing layers, providing additional insulating airspaces and enhanced performance.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

An insulating window unit for a building including adjacent glazed panels linked to each other by at least one translucent connection element having a structural function, wherein each glazed panel is a multiple glazing unit including plural sheets of glass enclosing at least one closed space between the sheets and including at least one translucent seal along a connection edge of same facing the other adjacent glazed panel.

A method and apparatus for heating and/or pressing sealant of an insulating glass unit. The apparatus may include an oven and a press. The oven includes a detector that detects an optical property of the insulating glass unit. The detected optical property is used to regulate the amount of energy applied to the insulating glass unit to adjust the amount of energy applied to the sealant. The press may include a displacement transducer that detects a pre-pressed thickness of the insulating glass unit. The measured pre-pressed thickness is used to automatically select a press thickness from a set of pressed IGU thicknesses.
