Abstract

Abstract This invention pertains to an apparatus and method for treating and coating newly formed glassware surfaces which are moving rapidly on conveyor means through an enclosure in which the glassware is exposed to streams of treatment gas, and particularly metal halide treatment gases, directed towards the glassware from orifices with a substantial component of the direction of travel of the streams of treatment gas being in the direction of travel of the glassware, thereby producing an even coating around the entire periphery of the glassware.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 124 words
GLASSWARE TREATING APPARATUS COMPRISING: AN ENCLOSURE HAVING ENTRANCE AND EXIT OPENING DEFINED IN OPPOSITE ENDS THEREEOF, CONVEYOR MEANS POSITIONED ADJACENT THE LOWER PORTION OF THE ENCLOSURE AND ALIGNED WITH BOTH THE ENTRANCE AND EXIT OPENINGS, AND TREATMENT GAS DISTRIBUTION MEANS LOCATED WITH THE ENCLOSURE TO PROVIDE STREAM OF TREATMENT GAS WITHIN THE ENCLOSURE, ALL OF SUCH STREAMS BEING DIRECTED PARTIALLY TOWARDS THE CONVEYOR DIRECTIONS BETWEEN ABOUT 10* AND 80* FROM THE DIRECTION OF TRAVEL OF THE CONVEYOR BELT WITH A SUBSTANTIAL COMPONEMT OF VELOCITY OF THE TREATMENT GAS STREAMS BEING IN THE DIRECTION OF TRAVEL OF THE CONVEYOR MEANS, WHEREBY GLASSWARE CARRIED THROUGH THE ENCLOSURE ON THE CON VEYOR MEANS TENDS TO TRAVEL WITH THE MOVING TREATMENT GAS RATHER THAN THROUGH THE TREATMENT GAS.
Claim 2
Dependent Claim 124 words
GLASSWARE TREATING APPARATUS COMPRISING: AN ENCLOSURE HAVING ENTRANCE AND EXIT OPENING DEFINED IN OPPOSITE ENDS THEREEOF, CONVEYOR MEANS POSITIONED ADJACENT THE LOWER PORTION OF THE ENCLOSURE AND ALIGNED WITH BOTH THE ENTRANCE AND EXIT OPENINGS, AND TREATMENT GAS DISTRIBUTION MEANS LOCATED WITH THE ENCLOSURE TO PROVIDE STREAM OF TREATMENT GAS WITHIN THE ENCLOSURE, ALL OF SUCH STREAMS BEING DIRECTED PARTIALLY TOWARDS THE CONVEYOR DIRECTIONS BETWEEN ABOUT 10* AND 80* FROM THE DIRECTION OF TRAVEL OF THE CONVEYOR BELT WITH A SUBSTANTIAL COMPONEMT OF VELOCITY OF THE TREATMENT GAS STREAMS BEING IN THE DIRECTION OF TRAVEL OF THE CONVEYOR MEANS, WHEREBY GLASSWARE CARRIED THROUGH THE ENCLOSURE ON THE CON VEYOR MEANS TENDS TO TRAVEL WITH THE MOVING TREATMENT GAS RATHER THAN THROUGH THE TREATMENT GAS.
Claim 3
Dependent Claim 33 words
Glassware treating apparatus as set forth in claim 1, wherein the streams of treatment gas are directed in a direction between 15* and 75* from the direction of travel of the conveyor belt.
Claim 4
Dependent Claim 58 words
Glassware treating apparatus as set forth in claim 1, wherein the treatment gas distribution means comprise manifolds disposed along each side of the conveyor means, and a plurality of inlet orifices defined in the manifolds and oriented with both a component towards the conveyor means and a substantial component in the direction of travel of the conveyor means.
Claim 5
Dependent Claim 17 words
Glassware treating apparatus as set forth in claim 3, wherein the conveyor means comprise a continuous belt.
Claim 6
Dependent Claim 17 words
Glassware treating apparatus as set forth in claim 4, wherein the continuous belt is a foraminous belt.
Claim 7
Dependent Claim 111 words
GLASSWARE TREATING APPARATUS COMPRISING: AND ENCLOSURE WITH ENTRANCE AND EXIT OPENING DEFINED IN OPPOSITE ENDS THEREOF, A CONVEYOR BELT POSITIONED AT THE LOWER PORTION OF THE ENCLOSURE AND ALIGNED THROUGH BOTH THE ENTRANCE AND EXIT OPENING, CONDUIT MEANS COMMUNICATING BOTH WITH THE EXTERIOR AND INTERIOR OF THE ENCLOSURE FOR SUPPLYING TREATMENT GAS TO THE INTERIOR OF THE ENCLOSURE, TREATMENT GAS MANIFOLDS CONNECTED TO THE CONDUIT MEANS AND DISPOSED IN THE ENCLOSURE ALONG OPPOSITE SIDES OF THE CONVEYOR BELT, AND INLET ORIFICES DEFINED IN THE MANIFOLDS AND ALL ORIENTED WITH A SUBSTANTIAL COMPONENT IN TE DIRECTION OF TRAVEL OF THE CONVEYOR BELT AND WITH A COMPONENT IN THE DIRECTION OF THE GLASSWARE.
Claim 8
Dependent Claim 111 words
GLASSWARE TREATING APPARATUS COMPRISING: AND ENCLOSURE WITH ENTRANCE AND EXIT OPENING DEFINED IN OPPOSITE ENDS THEREOF, A CONVEYOR BELT POSITIONED AT THE LOWER PORTION OF THE ENCLOSURE AND ALIGNED THROUGH BOTH THE ENTRANCE AND EXIT OPENING, CONDUIT MEANS COMMUNICATING BOTH WITH THE EXTERIOR AND INTERIOR OF THE ENCLOSURE FOR SUPPLYING TREATMENT GAS TO THE INTERIOR OF THE ENCLOSURE, TREATMENT GAS MANIFOLDS CONNECTED TO THE CONDUIT MEANS AND DISPOSED IN THE ENCLOSURE ALONG OPPOSITE SIDES OF THE CONVEYOR BELT, AND INLET ORIFICES DEFINED IN THE MANIFOLDS AND ALL ORIENTED WITH A SUBSTANTIAL COMPONENT IN TE DIRECTION OF TRAVEL OF THE CONVEYOR BELT AND WITH A COMPONENT IN THE DIRECTION OF THE GLASSWARE.
Claim 9
Dependent Claim 68 words
Glassware treating apparatus as set forth in claim 6, wherein the inlet orifices are arranged in a plurality of horizontal rows along the manifolds of the side of the manifold facing the conveyor belt, whereby treatment gas directed through such inlet orifices is propelled both towards and along the conveyor means at differing heigHts above the conveyor means substantially corresponding to the height of the glassware being treated.
Claim 10
Independent Claim 139 words
A method of treating glassware with a treatment gas, comprising: rapidly conveying a series of glassware articles to an enclosure, forming a mixture of treatment gas in a lighter carrier gas, conducting the mixture of treatment gas to at least one manifold located in the interior enclosure, expelling the treatment gas mixture under pressure through at least one inlet orifice defined in the manifold to form a substantially coherent, moving stream of treatment gas mixture, and directing all streams of treatment gas mixture into the enclosure in a direction at least partially in the direction in which the glassware articles are conveyed and at least partially towards the glassware, whereby the relative velocity between the articles being treated and the treatment gas is substantially less than the difference in the relative velocity of the glassware articles and the enclosure.
Claim 11
Independent Claim 139 words
A method of treating glassware with a treatment gas, comprising: rapidly conveying a series of glassware articles to an enclosure, forming a mixture of treatment gas in a lighter carrier gas, conducting the mixture of treatment gas to at least one manifold located in the interior enclosure, expelling the treatment gas mixture under pressure through at least one inlet orifice defined in the manifold to form a substantially coherent, moving stream of treatment gas mixture, and directing all streams of treatment gas mixture into the enclosure in a direction at least partially in the direction in which the glassware articles are conveyed and at least partially towards the glassware, whereby the relative velocity between the articles being treated and the treatment gas is substantially less than the difference in the relative velocity of the glassware articles and the enclosure.
Claim 12
Dependent Claim 19 words
A method of treating glassware as set forth in claim 7, wherein the treatment gas is a metallic halide.
Claim 13
Dependent Claim 24 words
A method of treating glassware as set forth in claim 9, wherein the treatment gas is stannic chloride and the carrier gas is air.
Claim 14
Dependent Claim 42 words
A method of treating glassware as set forth in claim 8, wherein a plurality of streams of treatment gas are formed and all directed towards the glassware and along the direction of travel of the glassware from each side of the enclosure.
Claim 15
Independent Claim 54 words
A METHOD OF TREATING GLASSWARE WITH A TREATMENT GAS DISPERSED IN A CARRIER GAS, COMPRISING: CONVEYING GLASSWARE THROUGH AN ENCLOSURE AND DIRECTING ALL STREAMS OF TREATMENT GAS AND CARRIER GAS BOTH TOWARDS THE GLASSWARE AND WITH A SUBSTANTIAL COMPONENT OF MOVEMENT OF THE TREATMENT GAS IN THE DIRECTION IN WHICH THE GLASSWARE IS CONVEYED.
Claim 16
Independent Claim 54 words
A METHOD OF TREATING GLASSWARE WITH A TREATMENT GAS DISPERSED IN A CARRIER GAS, COMPRISING: CONVEYING GLASSWARE THROUGH AN ENCLOSURE AND DIRECTING ALL STREAMS OF TREATMENT GAS AND CARRIER GAS BOTH TOWARDS THE GLASSWARE AND WITH A SUBSTANTIAL COMPONENT OF MOVEMENT OF THE TREATMENT GAS IN THE DIRECTION IN WHICH THE GLASSWARE IS CONVEYED.
