Abstract
Abstract A curved deflector for intercepting high velocity sprays of liquids thrown from a moving member has holes formed in the portion of the deflector remote from the member for permitting substantially all liquid collected by the deflector to pass through the holes and in so doing be substantially slowed in velocity, thereby substantially eliminating aeration from splashing and considerably reducing noise.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
In apparatus including a moving member from which liquid is thrown during movement thereof and at least one plate-like deflector positioned adjacent the member to intercept at least a portion of said liquid, the deflector extending generally transverse to the direction of movement of the member and having an inner edge located close to the member and an outer edge located remote from the member, and further having a curved transverse cross-section which is generally concave to the direction of movement of the liquid thrown from the member such that it intercepts and collects the liquid thereon as a moving layer, the improvement comprising means defining a multiplicity of holes located in a portion of the deflector adjacent to the outer edge and in a band along the length of the deflector remote from the member where substantially no liquid thrown from the member directly impinges for permitting substantially all liquid collected by the deflector to pass through said holes, a part of the liquid passing through and out of each hole as a stream moving at a velocity substantially less than the velocity with which the liquid was thrown from the member.
Claim 2
Dependent Claim
193 words
In apparatus including a moving member from which liquid is thrown during movement thereof and at least one plate-like deflector positioned adjacent the member to intercept at least a portion of said liquid, the deflector extending generally transverse to the direction of movement of the member and having an inner edge located close to the member and an outer edge located remote from the member, and further having a curved transverse cross-section which is generally concave to the direction of movement of the liquid thrown from the member such that it intercepts and collects the liquid thereon as a moving layer, the improvement comprising means defining a multiplicity of holes located in a portion of the deflector adjacent to the outer edge and in a band along the length of the deflector remote from the member where substantially no liquid thrown from the member directly impinges for permitting substantially all liquid collected by the deflector to pass through said holes, a part of the liquid passing through and out of each hole as a stream moving at a velocity substantially less than the velocity with which the liquid was thrown from the member.
Claim 3
Dependent Claim
49 words
The improvement according to claim 1 wherein the holes are arranged in staggered relation such that they present to the liquid layer collected by the deflector a total area for flow of the liquid through the deflector that is substantially uniform along the transverse extent of the liquid layer.
Claim 4
Dependent Claim
89 words
The improvement according to claim 1 wherein the thickness of the deflector in the region where the holes are located is such that in relation to the curvature of the deflector in said region and the sizes and configurations of the holes a quantity of liquid passes through a hole by being freed from centripetal force as it moves over a hole and by impinging substantially entirely on a portion of the wall of the hole that faces the direction of flow of the liquid layer along the deflector.
