Abstract: A method of applying a grooved lineal to the edge portion of a glass unit in the formation of a window component is provided. The method includes the steps of applying a triggerable sealant to the groove of the lineal, urging the edge portion of the glass unit into the groove, and triggering the sealant to form a seal between the groove and the edge portion of the glass unit. In one embodiment, the triggerable sealant is a dual state adhesive that can be placed in a first non-adhesive state by application of a temporary adhesion blocker. The lineal is urged onto the edge of the glass unit while the adhesive is in this first state and held in place until the adhesive transitions to its second adhesive state to bond and seal the glass within the groove.

Abstract: A quantitative determination of the identity, origin and migration of a volatile substance or mixture of substances, arising from food or food packaging during heating using microwave energy, can be accomplished. A novel process and equipment are disclosed in which a volatile substance or mixtures of constituent compounds, volatilized into the vapor space within or around microwave cooked food or a microwave cooking container, can be gathered and quantitatively analyzed for the identity, origin, chemical changes, migration routes and final locus of the volatile substance.
