Abstract: A resistance-heated vaporizer for vacuum depositing thin metallic coatings on glass panes or the like is disclosed with at least one metal strip that is placed in spaced parallel relationship to the pane and connected to a source of electricity and with at least one relatively flat pocket provided on the metal strip facing the pane. The pocket is made of an electrically conductive and net-like material.

Abstract: A heat reflecting window pane consisting of a laminate of a transparent support layer, an absorption layer, a silver reflecting layer and an anti-reflecting layer. A fifth layer of transparent material may also be provided.

Abstract: A stack of rectangular workpieces to be peripherally bonded to one another, such as a unit of two glass plates and an interposed spacer frame, is transported along a generally U-shaped horizontal path having two parallel runs and one transverse course constituted by a number of active or passive conveyor stages. A pair of power presses with complementarily oriented L-shaped jaws are inserted in the two runs, each press acting upon the leading and proximal edges of the stack. A control station common to the two runs is inserted between the two presses and carries an adhesive injector having a nozzle head alternately trainable upon a stack on one or the other press. A conveyor stage in each run, immediately downstream of the respective press, is bodily shiftable between that press and an adjoining stage to give the adhesive injector at the control station access to the press side clamping the leading edge of the stack.

Abstract: A planar workpiece of polygonal outline, such as a metal frame for use as a spacer in thermally insulating glass is stood on its edge and transported to a manipulator which tilts the workpiece about a horizontal axis to position one of its corners in a treatment location where it can be, for instance, soldered or brazed. Thereafter the workpiece is tilted over and set on an edge and either transported away to another such treatment location or positioned with its next corner in the same treatment location. The manipulator which tilts the workpiece in an upright position can be a plate with four sides or a pair of arms pivotal between horizontal and vertical positions.

Abstract: An acoustically and thermally insulated window structure comprising two outer panes and at least one inner pane with an outer spacer interposed between the outer panes and at least one further spacer defining a gap between inner panes when a plurality of the latter are provided. One of the inner panes is spaced at a predetermined relatively small distance from a corresponding outer pane and a body of moisture-absorbent material is disposed in fluid communication with a space within the inner panes.
