Abstract
Abstract The invention provides a method of and apparatus for applying two or more substances to a surface. According to the invention a plurality of nozzle means (111, 111') each having a plurality of aligned nozzles (113, 113') and each connected to a different source (119) of a plurality of different substances, are controlled by control means (123,125) to project droplets of the substances onto a surface in a predetermined pattern and so that the positions on said surface occupied by one of said substances will also be occupied by another said substance.

67 words
A method of applying two or more substances to a surface, the method comprising applying at least two substances to the surface, at least one of said substances being applied to the surface by projecting droplets thereof onto the surface in a predetermined pattern, each of the positions on said surface occupied by a said droplet of the one substance also being occupied by another said substance.
Claim 3
Independent Claim
56 words
A method of applying two or more substances to a surface, the method comprising projecting droplets of at least two said substances onto said surface in a predetermined pattern and so that the position on said surface occupied by each droplet of a first said substance will-also be occupied by a droplet of another said substance.
Claim 4
Independent Claim
56 words
A method of applying two or more substances to a surface, the method comprising projecting droplets of at least two said substances onto said surface in a predetermined pattern and so that the position on said surface occupied by each droplet of a first said substance will-also be occupied by a droplet of another said substance.
Claim 5
Dependent Claim
42 words
A method according to claim 1, wherein one of said substances is applied to the surface as a coating and at least one other said substance is applied to the surface by projecting droplets thereof onto the surface in a predetermined pattern.
Claim 6
Dependent Claim
32 words
A method according to claim 3, wherein first the surface is coated with one of said substances and then at least one other said substance is applied thereover by projecting droplets thereof.
Claim 7
Dependent Claim
23 words
A method according to claim 2, wherein the droplets of said at least two substances are directed to each said position substantially simultaneously.
Claim 8
Dependent Claim
63 words
A method according to claim 2, wherein droplets of one of said substances are first projected onto said surface in a predetermined pattern and then droplets of at least one other said substance are projected onto said surface so that the droplets of said at least one other substance occupy the same positions on the surface as the droplets of the one substance.
Claim 9
Independent Claim
80 words
A method according to any one of the preceding claims, which comprises causing each said substance which is to be projected onto said surface in the form of droplets to issue from a nozzle as a continuous stream of droplets, effecting relative movement between the nozzle and said surface, selectively electrically charging said droplets, and selectively creating an electrical field or fields whereby said droplets are selectively directed either to a required position on said surface or to a drain.
Claim 10
Independent Claim
79 words
A method according to any one of the preceding claims 1 to 6, which comprises causing each said substance which is to be projected onto said surface in the form of droplets to issue from nozzle means comprising a plurality of nozzles, effecting relative movement between the nozzle means and said surface, and selectively controlling the issue of droplets from each said nozzle of the nozzle means so that the droplets are projected onto said surface in required positions.
Claim 11
Dependent Claim
92 words
A method according to claim 8, insofar as this is dependant upon claim 2, which comprises arranging the nozzles of each said nozzle means in-spaced alignment laterally of the direction of relative movement between the nozzle means and said surface and with the corresponding nozzles of the different nozzle means aligned in the said direction of relative movement, and so controlling the projection of droplets of the different substances from the corresponding nozzles of the different nozzle means that the droplets will be caused to occupy the same position on the surface.
Claim 12
Dependent Claim
41 words
A method according to claim 9, which comprises producing signals indicative of the position of said surface relative to each of the nozzle means and using said signals to control the projection of-droplets of the different substances from the nozzle means.
Claim 13
Dependent Claim
85 words
Apparatus for applying two or more substances to a surface, the apparatus comprising at least two means for applying at least two substances to a surface, at least one of said means comprising means for projecting droplets of one of said substances onto a said surface and means for controlling the projection of said droplets in a predetermined pattern, the arrangement being such that the position on the surface occupied by each droplet of the one substance will also be occupied by another said substance.
Claim 14
Dependent Claim
85 words
Apparatus for applying two or more substances to a surface, the apparatus comprising at least two means for applying at least two substances to a surface, at least one of said means comprising means for projecting droplets of one of said substances onto a said surface and means for controlling the projection of said droplets in a predetermined pattern, the arrangement being such that the position on the surface occupied by each droplet of the one substance will also be occupied by another said substance.
Claim 15
Dependent Claim
