Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A process for glazing motor vehicles, the steps comprising: applying a sealant and adhesive composition to either a vehicle frame having one or more metal elements or to a window, inserting the window into the frame adjacent to the metal element, applying microwave energy from a radiational element located to one side of the window opposite the metal element to at least a portion of the composition in a pulse-like manner so that overheating of the portion of the composition to which the microwaves are applied is avoided, so as to heat and initiate curing of at least a portion of the composition, thereby securing the window to the frame wherein the pulse-like manner is that a first group of microwaves is applied during an initial period, followed by an interval period during which continuous microwave energy is applied, and subsequently at least one additional group of microwaves is applied during at least one additional period.
Claim 2
Dependent Claim
156 words
A process for glazing motor vehicles, the steps comprising: applying a sealant and adhesive composition to either a vehicle frame having one or more metal elements or to a window, inserting the window into the frame adjacent to the metal element, applying microwave energy from a radiational element located to one side of the window opposite the metal element to at least a portion of the composition in a pulse-like manner so that overheating of the portion of the composition to which the microwaves are applied is avoided, so as to heat and initiate curing of at least a portion of the composition, thereby securing the window to the frame wherein the pulse-like manner is that a first group of microwaves is applied during an initial period, followed by an interval period during which continuous microwave energy is applied, and subsequently at least one additional group of microwaves is applied during at least one additional period.
Claim 3
Dependent Claim
29 words
The process of claim 1, wherein the first group of microwaves has an initial amplitude, and each additional group of microwaves has an amplitude less than the initial amplitude.
Claim 4
Dependent Claim
21 words
The process of claim 1, wherein the period during which each additional group of microwaves is applied has the same length.
Claim 5
Dependent Claim
30 words
The process of claim 1, wherein the sealant and adhesive composition is slow curing and microwave energy is applied to the composition before the window is inserted into the frame.
Claim 6
Dependent Claim
20 words
The process of claim 1, wherein the metal element is preheated in the vicinity of the sealant and adhesive composition.
Claim 7
Dependent Claim
20 words
The process of claim 5, wherein the metal element is heated to a temperature of about 75° to 100° C.
Claim 8
Dependent Claim
20 words
The process of claim 5, wherein the metal element is heated to a temperature of about 80° to 95° C.
