Abstract: A method of manufacturing a multi-glass panel unit with a spacer frame consisting of four straight rails held together by four angular coupling means the arms of which are inserted method including the steps of arranging the rails in spaced relationship, applying an adhesive on side surfaces of the rails, pushing the rails together, mounting the glass panels on the sides of the frame, and pressing sealing material into cavities in the corners of the frame.

Abstract: Apparatus for applying plastic material to the four edges of a multiple-pane window comprises first and second pairs of nozzles and first and second carriers for moving the window horizontally between the nozzles of each pair in succession. Transfer means, particularly a rotating column with a laterally extending arm, transfers the window from one carrier to the other and rotates the window to bring the edges uncoated at the first station in position for coating at the second station. The transfer device is advantageously correlated with the downstream limit of the first carrier and the upstream limit of the second carrier to transfer and rotate the window about its axis of symmetry. A function of the window length on the first carrier is measured and the separation of the nozzles of the second pair adjusted accordingly. A supply device centers a window and deposits it in a predetermined centered position in the first carrier.

Abstract: A face of a sheet, e.g. of glass, is moved past an extrusion nozzle to deposit a plastic filament adjacent a first edge thereof. The movement is interrupted when a corner is reached. The nozzle and sheet are moved away from each other to detach the filament adjacent the corner and the sheet is rotated to present its next edge to the nozzle while retaining the continuity of the filament. The nozzle and sheet are then returned to depositing position and the relative movement resumed to deposit the filament adjacent the next edge. The apparatus includes means for raising the sheet from conveyor belts and raising the extrusion devive by a greater amount, and then turning the sheet by a suction cup arm, the sheet being supported by rollers during the turning. A detector monitors the position of the sheet and controls the operation of the apparatus.

Abstract: In a transparent laminated window or canopy for aircraft and the like, flexible fabric tape impregnated with a silicone elastomeric adhesive applied against a surface of one of the plies or reinforcements of the window is used to bond at least one of the plies or reinforcements to another element of the laminated window or to a reinforcing frame of an aircraft panel which comprises the laminated window. Such tape is easier to apply during the assembly operation than previously used silicone pastes, thereby reducing the cost of fabricating aircraft panels incorporating said window or canopy without paying any unduly large penalty in adhesion between the elements of the panel.

Abstract: Insulating glass units sealed with a gradient cure hot-melt butyl rubber sealant composition are disclosed.

Abstract: A composition based on butyl rubber resins and filler particularly useful for hot melt application as a sealant for combining a plurality of glass panes in an insulating glazing unit in which improved workability in heated condition is secured without adversely affecting its other properties through inclusion of a minor amount of a thermoplastic block copolymer of polystyrene and polybutadiene or polystyrene and polyisoprene.

Abstract: A fire and impact resistant window assembly comprising a multi-part centrally open marginal frame having an intermediate or inner groove which faces inwardly and first and second outer grooves which also face inwardly. The intermediate or inner groove receives marginal portions of a pane of fire glass which is thus secured in the frame and extends across the central opening thereof. The outer grooves respectively receive marginal portions of first and second panes of deflectable impact resistant polycarbonate and thus secure the panes in opposite spaced relationship with the fire glass. One pane of polycarbonate is approximately one half (1/2) inch in thickness and is spaced from the fire glass a distance of 0.35 inches. The other pane of polycarbonate is approximately one fourth (1/4) inch in thickness and is spaced from the fire glass a distance somewhat in excess of 0.35 inches.

Abstract: A method of fabricating insulating glass units with a hot-melt butyl rubber sealant composition is disclosed as are insulating glass units produced by the method of this invention.

Abstract: A method of maintaining edge strength of a piece of glass i.e. preventing unintentional damage such as chips and/or scratches to the edges of the piece of glass during handling, processing and/or shipping is disclosed. A sheet of glass having dimensions greater than the desired size of the piece of glass is cut from a glass ribbon. The sheet of glass is pseudosubsurface scored or subsurface scored within the edges to define the piece of glass and to provide trim around the piece of glass which trim protects the edges of the piece of glass against unintentional damage. Thereafter, the sheet of glass is stored or processed, e.g., coating a surface of the sheet of glass with a transparent metal coating. The trim is removed from the sheet of glass at a fabrication station and the piece of glass having edges free of unintentional damage is used in the fabrication of a product e.g., a multiple glazed unit.

Abstract: Manufacture of double or plural pane insulating packages by placing panes together with a spacer, thereby leaving an interspace at the periphery into which cement is injected. Two nozzles are used to inject cement into the interspace, starting from a common starting region and working in opposite directions around the periphery to a common terminal point. Conveyors and control systems are provided to mechanize the process.

Abstract: In a cell comprising a pair of oppositely disposed, flat substrates, and an edge seal maintaining the substrates in spaced apart relation, a fabrication process in which the two substrates are disposed in oppositely disposed relation and in contact with a glass frit bead disposed therebetween, and spacer plates are disposed between the substrates between the bead and the edges of the substrates. The glass bead is heat softened and the two substates forced towards one another against the bead until further inward movement is prevented by contact of the substrates with the spacer plates.

Abstract: A multiple glazed glass article including two glass panels separated by a spacer and held in a marginal frame is disclosed. Two coatings are present on one of the glass panels providing the article with useful and esthetic reflective and transmission properties. One coating preferably includes a metal such as silver, chromium, iron, cobalt or nickel and the other coating preferably includes a metal oxide such as iron oxide or copper oxide. The metal oxide layer is essentially the oxide of a metal other than the metal of the metal layer.
