Abstract
Abstract A recovery system is disclosed herein which includes spraygathering exhaust hoods positioned opposite the spraying nozzles. The exhaust hoods cooperatively communicate with inlet ducts which, in turn, connect to a catch box arrangement. An exhaust duct exits from the catch box. Connected in line with the exhaust duct is an exhaust fan arrangement which creates an airflow through the hood-inlet duct-catch box-exhaust duct connection to thereby attract any overspray in the vicinity of the exhaust hoods. The overspray is sucked into the hoods down the inlet duct and is deflected towards the bottom of the catch box by a baffle arrangement within the box. The deflected spray-air mixture physically contacts the walls and bottom of the catch box with a small percentage exiting via the exhaust duct network. The greater percentage of the captured spray is deposited on the bottom of the catch box in an accessible tray, from where it can be readily recovered.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
256 words
A material recovery system for a glass bottle spraying apparatus wherein the solution sprayed is a liquid containing a tin compound, comprising: a. spray channeling means for gathering the solution not deposited on said bottles; b. collecting means, including a removable tray connected cooperatively with said channeling means; said channeling means including at least one exhaust hood and intake duct, said exhaust hood having generally a curved design, whereby sharp corners and recesses are eliminated or minimized to avoid, otherwise, the collection of said sprayed solution in said corners and recesses, said exhaust hood connected to the sidewall of said intake duct, said intake duct straightly extending therefrom downward into the top of said collecting means; c. means for creating a flow of said sprayed, undeposited solution into said channeling means and through said recovery system; said flow creating means including at least one exhaust duct connected to said collecting means, said intake duct and exhaust duct physically arranged at the interface with said collecting means such that said collected spray undergoes a 180* change of direction in passing from said intake duct to said exhaust duct; and d. means for deflecting substantially all of said flow entering said collecting means via said intake duct, downward towards the bottom of said tray and into physical contact therewith said flow of sprayed, undeposited solution entering said collecting means out of said intake duct, substantially parallel to the plane of said deflecting means in a substantially vertical, downward direction, whereby there is insubstantial contact with said deflecting means.
Claim 2
Dependent Claim
256 words
A material recovery system for a glass bottle spraying apparatus wherein the solution sprayed is a liquid containing a tin compound, comprising: a. spray channeling means for gathering the solution not deposited on said bottles; b. collecting means, including a removable tray connected cooperatively with said channeling means; said channeling means including at least one exhaust hood and intake duct, said exhaust hood having generally a curved design, whereby sharp corners and recesses are eliminated or minimized to avoid, otherwise, the collection of said sprayed solution in said corners and recesses, said exhaust hood connected to the sidewall of said intake duct, said intake duct straightly extending therefrom downward into the top of said collecting means; c. means for creating a flow of said sprayed, undeposited solution into said channeling means and through said recovery system; said flow creating means including at least one exhaust duct connected to said collecting means, said intake duct and exhaust duct physically arranged at the interface with said collecting means such that said collected spray undergoes a 180* change of direction in passing from said intake duct to said exhaust duct; and d. means for deflecting substantially all of said flow entering said collecting means via said intake duct, downward towards the bottom of said tray and into physical contact therewith said flow of sprayed, undeposited solution entering said collecting means out of said intake duct, substantially parallel to the plane of said deflecting means in a substantially vertical, downward direction, whereby there is insubstantial contact with said deflecting means.
