Abstract
Abstract A reciprocating crossfire set of rinsing nozzles rinses the surface of a glass sheet while maintaining a uniform thickness of rinsing medium in an area on the glass surface where a subsequent spraying operation is to be carried out. The rinsing nozzles are angled obliquely downward, rearward and outward, and rinse water or other medium is supplied at a rate sufficient to force excess rinsing medium off the side and the trailing edge of the sheet, rather than being delivered into the spray area or accumulated along its trailing edge portion. The uniform thickness of rinsing medium prepares the substrate for receiving a more uniform transparent metal-boron coating in the spraying operation that follows.

Claim 1
Independent Claim
245 words
A METHOD OF RINSING THE SURFACE OF A GLASS SHEET COMPRISING THE STEPS OF: PROVIDING A RINSE SET HAVING A PLURALITY OF FAN-SHAPED SPRAYS OF WATER TOWARD A GIVEN SUBSTANTIALLY HORIZONTAL PLANE WHEREIN EACH SPRAY HAS AN APEX ANGLE S, MOVING THE SHEET OF GLASS IN A FIRST DIRECTION ALONG AN ARTICLE MOVEMENT PATH IN THE GIVEN SUBSTANTIALLY HORIZONTAL PLANE BENEATH THE RINSE SET, DIRECTING THE FUN-SHAPED SPRAY (1) AT A FIRST OBLIQUE ANGLE TO A FIRST PLANE PERPENDICULAR TO THE GIVEN HORIZONTAL PLANE AND PARALLEL TO THE ARTICLE MOVEMENT PATH WHEREIN THE FIRST OBLIQUE ANGLE IS BETWEEN ABOUT 35* AND ABOUT 50* AND (2) AT A SECOND OLIQUE ANGLE TO A SECOND PLANE PERPENDICULAR TO THE GIVEN HORIZONTAL PLANE AND THE FIRST PLANE WHEREIN THE SECOND OBLIQUE ANGLE DEFINES AN ANGLE A THAT IS MEASURED FROM THE ARTICLE MOVEMENT PATH AND IS 90* PLUS ONE-HALF OF THE APEX ANGLE S AND BETWEEN ABOUT 105* AND ABOUT 120* TO APPLY A COMPONENT OF MOTION TO THE WATER IN THE DIRECTION OF THE TRAILING EDGE OF THE MOVING GLASS SHEET, AND RECIPROCATING THE RINSE SET ALONG A RECIPROCATING AXIS THAT IS SPACED FROM AND TRANSVERSE TO THE ARTICLE MOVEMENT PATH WHEREIN RECIPROCATING THE RINSE SET IN A FIRST DIRECTION MOVES THE WATER IN A FIRST DIRECTION ALONG THE SURFACE THE GLASS SHEET AND RECIPROCATING THE RINSE SET IN A SECOND DIRECTION OPPOSITE TO THE FIRST DIRECTION MOVES THE WATER ON THE SURFACE IN A SECOND DIRECTION.

A METHOD OF RINSING THE SURFACE OF A GLASS SHEET COMPRISING THE STEPS OF: PROVIDING A RINSE SET HAVING A PLURALITY OF FAN-SHAPED SPRAYS OF WATER TOWARD A GIVEN SUBSTANTIALLY HORIZONTAL PLANE WHEREIN EACH SPRAY HAS AN APEX ANGLE S, MOVING THE SHEET OF GLASS IN A FIRST DIRECTION ALONG AN ARTICLE MOVEMENT PATH IN THE GIVEN SUBSTANTIALLY HORIZONTAL PLANE BENEATH THE RINSE SET, DIRECTING THE FUN-SHAPED SPRAY (1) AT A FIRST OBLIQUE ANGLE TO A FIRST PLANE PERPENDICULAR TO THE GIVEN HORIZONTAL PLANE AND PARALLEL TO THE ARTICLE MOVEMENT PATH WHEREIN THE FIRST OBLIQUE ANGLE IS BETWEEN ABOUT 35* AND ABOUT 50* AND (2) AT A SECOND OLIQUE ANGLE TO A SECOND PLANE PERPENDICULAR TO THE GIVEN HORIZONTAL PLANE AND THE FIRST PLANE WHEREIN THE SECOND OBLIQUE ANGLE DEFINES AN ANGLE A THAT IS MEASURED FROM THE ARTICLE MOVEMENT PATH AND IS 90* PLUS ONE-HALF OF THE APEX ANGLE S AND BETWEEN ABOUT 105* AND ABOUT 120* TO APPLY A COMPONENT OF MOTION TO THE WATER IN THE DIRECTION OF THE TRAILING EDGE OF THE MOVING GLASS SHEET, AND RECIPROCATING THE RINSE SET ALONG A RECIPROCATING AXIS THAT IS SPACED FROM AND TRANSVERSE TO THE ARTICLE MOVEMENT PATH WHEREIN RECIPROCATING THE RINSE SET IN A FIRST DIRECTION MOVES THE WATER IN A FIRST DIRECTION ALONG THE SURFACE THE GLASS SHEET AND RECIPROCATING THE RINSE SET IN A SECOND DIRECTION OPPOSITE TO THE FIRST DIRECTION MOVES THE WATER ON THE SURFACE IN A SECOND DIRECTION.
Claim 3
Independent Claim
158 words
A method of rinsing a surface of an article, comprising the steps of: providing a rinse set having at least one fan-shaped spray having an apex angle S; moving the article in a first direction along an article movement path in a given plane; directing the at least one fan-shaped spray (1) at a first oblique angle to a first plane perpendicular to the given plane and parallel to the article movement path wherein the first oblique angle is between about 35* and about 50* and (2) at a second oblique angle to a second plane perpendicular to the given plane and the first plane wherein the second oblique angle defines an angle A that is measured from the article movement path and is 90* plus one-half of the apex angle S and between about 105* to about 120*; reciprocating the rinse set along a reciprocating path that is spaced from and transverse to the article movement path.
Claim 4
Independent Claim
