Abstract
Abstract The invention comprises apparatus for pouring surface treatment liquids onto substantially level workpieces to enable different liquids with different viscosities to be used to good effect comprising an elongated liquid container having upper liquid feed means and walls defining a longitudinally extending pouring gap between their surfaces in the lower region of said container, characterized by an overflow device for adjusting said liquid level in said container which device is located on said container and communicates with said liquid container; the surface of said overflow device defining openings at various levels which are offset relative to one another and alternately closable whereby said liquid level may be adjusted. The overflow device is preferably a rotatable hollow cylindrical body and is laterally arranged of the liquid container, the opening(s) defined by said surface and in communication with said liquid being differently locatable with respect to the liquid surface by rotation of said cylindrical body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
Apparatus for pouring surface treatment liquids of varying viscosity onto substantially horizontally held panel or leaf-like workpieces, comprising a longitudinal liquid container having an upper liquid supply means and a lower, elongated pouring gap, said liquid container having at least one vertically extending slot formed in a side wall thereof, at least one adjustable overflow device mounted on said side wall of said liquid container, said overflow device having a vertically extending slot formed in one wall thereof and said overflow slot being in register with said container slot, a hollow cylinder rotatably mounted within said overflow device and having a lower outlet and a plurality of lateral supply openings which are arranged vertically and laterally offset relative to one another, and means for rotating said cylinder to a position whereby one of said supply openings is in register with said container slot and said overflow slot so that any liquid above the lowermost periphery of said registered supply opening is discharged through said lower outlet and determines the liquid level in said container.
Claim 2
Dependent Claim
174 words
Apparatus for pouring surface treatment liquids of varying viscosity onto substantially horizontally held panel or leaf-like workpieces, comprising a longitudinal liquid container having an upper liquid supply means and a lower, elongated pouring gap, said liquid container having at least one vertically extending slot formed in a side wall thereof, at least one adjustable overflow device mounted on said side wall of said liquid container, said overflow device having a vertically extending slot formed in one wall thereof and said overflow slot being in register with said container slot, a hollow cylinder rotatably mounted within said overflow device and having a lower outlet and a plurality of lateral supply openings which are arranged vertically and laterally offset relative to one another, and means for rotating said cylinder to a position whereby one of said supply openings is in register with said container slot and said overflow slot so that any liquid above the lowermost periphery of said registered supply opening is discharged through said lower outlet and determines the liquid level in said container.
Claim 3
Dependent Claim
55 words
Apparatus as claimed in claim 1, wherein said means for rotating said cylinder includes a worm gear connected to said hollow cylinder, a rotating spindle to drive said worm gear, said spindle extending in a longitudinal direction parallel to said liquid container and a handwheel to operate said spindle from one end of said apparatus.
Claim 4
Dependent Claim
18 words
Apparatus as claimed in claim 1, wherein said hollow cylinder is rotatable by means of an adjustment device.
Claim 5
Dependent Claim
44 words
Apparatus as claimed in claim 1, wherein said pouring gap is defined on one side by a baffle plate and on the other side by an adjustable pouring lip, said baffle plate being bent at an angle and retained in position by permanent magnets.
Claim 6
Dependent Claim
22 words
Apparatus as claimed in claim 4, wherein said pouring lip is mounted so as to be laterally displaceable by means of screws.
Claim 7
Dependent Claim
148 words
Apparatus for pouring surface treatment liquids of varying viscosity onto substantially horizontally held panel or leaf-like workpieces, comprising an elongated liquid container having an upper liquid supply means and a lower, elongaTed pouring gap, said liquid container having at least one vertical slot formed in a side wall thereof, at least one adjustable overflow device mounted on said side wall of said liquid container, said overflow device having a vertical slot formed therein and being in register with said container slot, a hollow cylinder rotatably mounted within said adjustable overflow device and having a lower outflow and a plurality of supply openings which are spaced along a helical line around said hollow cylinder, said supply openings each having a maximum width corresponding to the width of said liquid container slot and said overflow device slot, and means for rotating said hollow cylinder from one end of said apparatus.
Claim 8
Dependent Claim
148 words
Apparatus for pouring surface treatment liquids of varying viscosity onto substantially horizontally held panel or leaf-like workpieces, comprising an elongated liquid container having an upper liquid supply means and a lower, elongaTed pouring gap, said liquid container having at least one vertical slot formed in a side wall thereof, at least one adjustable overflow device mounted on said side wall of said liquid container, said overflow device having a vertical slot formed therein and being in register with said container slot, a hollow cylinder rotatably mounted within said adjustable overflow device and having a lower outflow and a plurality of supply openings which are spaced along a helical line around said hollow cylinder, said supply openings each having a maximum width corresponding to the width of said liquid container slot and said overflow device slot, and means for rotating said hollow cylinder from one end of said apparatus.
Claim 9
Dependent Claim
125 words
Apparatus for pouring liquids onto workpieces moved therebelow, comprising a container for receiving liquids, said container having a slot formed in a wall thereof and a lower pouring gap, an overflow device mounted on said wall of said liquid container, said overflow device having a slot in register with said container slot, a hollow cylinder rotatably mounted within said overflow device and having a plurality of openings offset vertically and laterally relative to each other, and means for rotating said cylinder to a position whereby one of said openings is in register with said container slot and said overflow slot so that the height of the liquid and its static pressure may be varied in order to control the flow velocity of the pouring liquid.
Claim 10
Dependent Claim
125 words
Apparatus for pouring liquids onto workpieces moved therebelow, comprising a container for receiving liquids, said container having a slot formed in a wall thereof and a lower pouring gap, an overflow device mounted on said wall of said liquid container, said overflow device having a slot in register with said container slot, a hollow cylinder rotatably mounted within said overflow device and having a plurality of openings offset vertically and laterally relative to each other, and means for rotating said cylinder to a position whereby one of said openings is in register with said container slot and said overflow slot so that the height of the liquid and its static pressure may be varied in order to control the flow velocity of the pouring liquid.
