Abstract
Abstract A method comprising positioning, in a narrow vertical elongated space, an apparatus comprising a vertical guide track supporting a vertically displaceable carriage, said carriage having means to apply a coating to one of the said walls; securing the guide track against movement in the narrow vertical elongated space; moving the carriage vertically on the guide track while applying a coating from the carriage to one of the said walls as a vertical band; moving the guide track adjacent an area of the same wall which has not been so coated and again securing the guide track; moving the carriage vertically on the guide track while applying a coating from the carriage to the same wall as a vertical band; and repeating the described application of coating bands until a substantial portion of the wall is coated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A method of applying a coating to one of two walls forming a narrow vertical elongated space, comprising: positioning, in the narrow vertical elongated space, an apparatus comprising a vertical guide track supporting a vertically displaceable carriage thereon, said carriage having means to apply a coating to one of the said walls; securing the guide track against movement lateral to the two walls and sideways in the narrow vertical elongated space; moving the carriage vertically on the guide track while applying a coating from the carriage to one of the said walls as a vertical band extending for a substantial part of the height of the elongated space; moving the guide track adjacent an area of the same wall which has not been so coated and again securing the guide track against lateral and sideways movement; moving the carriage vertically on the guide track while applying a coating from the carriage to the same wall as a vertical band extending for a substantial part of the height of the elongated space; and repeating the described application of coating bands until a substantial portion of the wall is coated.
Claim 2
Independent Claim
188 words
A method of applying a coating to one of two walls forming a narrow vertical elongated space, comprising: positioning, in the narrow vertical elongated space, an apparatus comprising a vertical guide track supporting a vertically displaceable carriage thereon, said carriage having means to apply a coating to one of the said walls; securing the guide track against movement lateral to the two walls and sideways in the narrow vertical elongated space; moving the carriage vertically on the guide track while applying a coating from the carriage to one of the said walls as a vertical band extending for a substantial part of the height of the elongated space; moving the guide track adjacent an area of the same wall which has not been so coated and again securing the guide track against lateral and sideways movement; moving the carriage vertically on the guide track while applying a coating from the carriage to the same wall as a vertical band extending for a substantial part of the height of the elongated space; and repeating the described application of coating bands until a substantial portion of the wall is coated.
Claim 3
Dependent Claim
18 words
A method according to claim 1 in which successive coating bands are placed adjoining previously applied coating bands.
Claim 4
Dependent Claim
14 words
A method according to claim 1 in which the coating is an insulating material.
Claim 5
Dependent Claim
16 words
A method according to claim 3 in which the insulating material is a solid polymeric foam.
Claim 6
Dependent Claim
21 words
A method according to claim 1 in which the coating band is applied by spraying the coating on in horizontal passes.
Claim 7
Dependent Claim
18 words
A method according to claim 1 in which the walls are vertical cylindrical circular walls equally spaced apart.
Claim 8
Dependent Claim
15 words
A method according to claim 1 or 6 in which the walls are metal plate.
Claim 9
Dependent Claim
22 words
A method according to claim 3 in which the full thickness of the insulating material band is applied in several thin layers.
Claim 10
Dependent Claim
20 words
A method according to claim 8 in which each thin layer is applied by one vertical movement of the carriage.
Claim 11
Dependent Claim
25 words
A method according to claim 3 in which the full thickness of the insulating material band is applied in one vertical movement of the carriage.
