Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
175 words
An apparatus for processing workpieces comprising guide means having longitudinally spaced inlet and outlet ends for receiving and movably and guidably supporting a workpiece during its travel therealong, first nozzle meanS for discharging a first stream of treating fluid in impinging relationship against a workpiece traveling along said guide means in a manner to induce movement of the workpiece toward said outlet end, second nozzle means for discharging a second stream of treating fluid in impinging relationship against a workpiece in said guide means at a location longitudinally spaced toward said outlet end from the point of impingement of said first stream, said second stream oriented to oppose the travel of a workpiece toward said outlet end, said first and said second streams controlled to effect a conveyance of a workpiece through said apparatus and a deceleration in its speed at a position intermediate of its travel along said guide means in response to the opposition of said second stream whereby intimate contact of said treating fluid with the surfaces of a workpiece is obtained.
Claim 2
Independent Claim
175 words
An apparatus for processing workpieces comprising guide means having longitudinally spaced inlet and outlet ends for receiving and movably and guidably supporting a workpiece during its travel therealong, first nozzle meanS for discharging a first stream of treating fluid in impinging relationship against a workpiece traveling along said guide means in a manner to induce movement of the workpiece toward said outlet end, second nozzle means for discharging a second stream of treating fluid in impinging relationship against a workpiece in said guide means at a location longitudinally spaced toward said outlet end from the point of impingement of said first stream, said second stream oriented to oppose the travel of a workpiece toward said outlet end, said first and said second streams controlled to effect a conveyance of a workpiece through said apparatus and a deceleration in its speed at a position intermediate of its travel along said guide means in response to the opposition of said second stream whereby intimate contact of said treating fluid with the surfaces of a workpiece is obtained.
Claim 3
Dependent Claim
37 words
The apparatus as defined in claim 1, further including a housing encircling at least a portion of said guide means for intercepting the streams of said treating fluid and for facilitating a return thereof to a reservoir.
Claim 4
Dependent Claim
31 words
The apparatus as defined in claim 1, wherein said first and said second nozzle means are oriented so that said first and said second streams do not impinge upon each other.
Claim 5
Dependent Claim
36 words
The apparatus as defined in claim 1, wherein said guide means comprise a plurality of longitudinally extending guide rods arranged in circumferentially spaced increments and defining therewith a longitudinally extending passageway through which the workpieces travel.
Claim 6
Dependent Claim
54 words
The apparatus as defined in claim 1, wherein said inlet end and said outlet end of said guide means include coupling means for removably securing the outlet end of one said apparatus to the inlet end of another one of said apparatus with each of said guide means thereof disposed in workpiece receiving alignment.
Claim 7
Dependent Claim
34 words
The apparatus as defined in claim 1, wherein said first nozzle means and said second nozzle means are operative to discharge said first stream and said second stream in a substantially non-divergent stream configuration.
Claim 8
Dependent Claim
42 words
The apparatus as defined in claim 1, in which said first nozzle means and said second nozzle means are oriented so that said first stream and said second stream pass through without contacting said guide means which are of a foraminous structure.
Claim 9
Dependent Claim
54 words
The apparatus as defined in claim 1, wherein said outlet end of said guide means is disposed in longitudinal alignment with separating means including a third nozzle means for discharging a blast of gas against a workpiece to effect an acceleration thereof and a removal of substantially all of the residual treating fluid thereon.
Claim 10
Dependent Claim
45 words
The apparatus as defined in claim 8, comprising a plurality of said apparatuses disposed in end-to-end relationship wherein each said apparatus performs a specific treatment and wherein a workpiece is subjected to a plurality of treatments upon travel through the plurality of said processing units.
Claim 11
Dependent Claim
43 words
The apparatus as defined in claim 1, wherein said first and said second nozzle means further include fluid guidance means for directionally orienting the flow of said treating fluid in a direction substantially parallel to the axis of discharge of said nozzle means.
Claim 12
Dependent Claim
123 words
In an apparatus for applying a treating liquid to the surfaces of a workpiece, the improvement comprising a separation section for removing the residual treating liquid from the surfaces of a workpiece at the completion of the liquid treatment including guide means formed with an entrance end for receiving a workpiece from a liquid treating operation and an exit end longitudinally spaced therefrom, nozzle means disposed adjacent to said guide means for discharging a high velocity blast of gas against a workpiece traveling along said guide means, said nozzle means oriented in a direction to effect rapid acceleration of a workpiece toward said exit end upon impingement of said blast thereagainst effecting a removal of substantially all of the residual treatIng liquid therefrom.
Claim 13
Dependent Claim
123 words
In an apparatus for applying a treating liquid to the surfaces of a workpiece, the improvement comprising a separation section for removing the residual treating liquid from the surfaces of a workpiece at the completion of the liquid treatment including guide means formed with an entrance end for receiving a workpiece from a liquid treating operation and an exit end longitudinally spaced therefrom, nozzle means disposed adjacent to said guide means for discharging a high velocity blast of gas against a workpiece traveling along said guide means, said nozzle means oriented in a direction to effect rapid acceleration of a workpiece toward said exit end upon impingement of said blast thereagainst effecting a removal of substantially all of the residual treatIng liquid therefrom.
Claim 14
Dependent Claim
32 words
The apparatus as defined in claim 11, further including a housing encircling at least a portion of said guide means for intercepting and recovering the residual treating liquid removed from a workpiece.
Claim 15
Dependent Claim
73 words
The apparatus as defined in claim 11, wherein the workpiece comprises an open-ended elongated container and said guide means movably support the container in a longitudinally oriented position with the open end thereof facing rearwardly and wherein said nozzle means is aimed to direct said blast into the open end and into the interior of the container to effect a displacement of any residual treating liquid therein and an acceleration of the container.
Claim 16
Dependent Claim
17 words
The apparatus as defined in claim 11, wherein said blast is discharged continuously from said nozzle means.
Claim 17
Dependent Claim
55 words
The apparatus as defined in claim 11, further including sensing means for sensing the presence of a workpiece traveling along said guide means and supply means operative in response to said sensing means for supplying pressurized gas to said nozzle means for discharge therefrom in timed relationship so as to impinge against the workpiece sensed.
