Title: Improvements in or relating to sealing double glazing units
Inventor: ROSE ALAN DAVID
IPC: C03C27/12
Filed: 1966-10-14
Abstract: 1,206,751. Multiple-glazing units. BITUMEN INDUSTRIES Ltd. 6 Oct., 1967 [14 Oct., 1966], No. 45954/66. Heading C1M. [Also in Division E1] A method of manufacturing a double glazing unit comprises positioning around the entire periphery of one face of a first sheet of glass a strip of material which is heat curable to a resilient state and which has an electric resistance wire extending therethrough, positioning a second sheet of glass against the strip and passing a current through the wire to heat the wire and cause the elastomeric material to soften and cure to a resilient state thus to provide a mixture proof seal between the two glass sheets. To obtain a good seal it is preferred to coat the peripheral surfaces of each sheet with a silicone resin primer. In one embodiment (Fig. 1) peripheral portions 13, 14 of two sheets of glass 2, 4 are coated with the primer. A strip 6 of material (e.g. a chloroprene rubber) and approximately 5/16 inch diameter and having a conductor wire 8 of 90% coppernickel alloy is laid all round the primed periphery 13 of sheet 2, sheet 4 is then placed with its periphery 14 against the strip 6, an external spacing member (not shown) being used to maintain the sheets in their desired positions. An electric current is passed through wire 8 to cause the strip 6 to soften and cure to resilient state and form a seal. In two alternative embodiments spacing means in the form of a strip 22 (Fig. 4, not shown) and a frame 32 (Fig. 6, not shown) are fitted around the inner edge of the strip 6 prior to the positioning of the second sheet, and thus form a permanent part of the seal. If desired a desiccant may be incorporated in the spacing member. Also more than one conductor wire may be incorporated into the strip of material. Other suitable materials are butyl rubber, ethylene propylene terpolymer, styrene-butadiene rubbery copolymer. The conductor wire may be insulated.
