Abstract
Abstract A cell suitable for plating, etching, rinsing, or cleaning a wire in a continuous wire plating operation. A fluid contacts the wire in the central bore of a diffuser which has several distinct groups of fluid inlet ducts and several distinct groups of fluid outlet ducts longitudinally offset in an interlaced sequence along the longitudinal axis of the bore. The individual ducts of the groups of inlet ducts are angularly offset with respect to the individual ducts of the groups of outlet ducts. The angular offset provides the necessary fluid swirling action for uniform plating and the longitudinal offset provides a directional fluid flow which assists the wire through the cell. A fluid stream having a directional component transverse to the longitudinal axis of the bore prevents leakage of fluid from the cell.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A fluid diffuser having an interior lengthwise cavity, distinct groups of fluid inlet ducts communicating with said cavity and disposed along the length of said cavity, and distinct groups of fluid outlet ducts communicating with said cavity and disposed along the length of said cavity in an interlaced sequence with said groups of fluid inlet ducts, the individual ducts of said groups of inlet ducts are angularly offset with respect to the individual ducts of said groups of outlet ducts, and a group of annular channels formed in the exterior surface of said diffuser, said group of channels being equal in number to the additive number of said groups of inlet ducts and said groups of outlet ducts, each one of said groups of fluid inlet ducts and said groups of fluid outlet ducts communicates with a different one of said channels.
Claim 2
Dependent Claim
142 words
A fluid diffuser having an interior lengthwise cavity, distinct groups of fluid inlet ducts communicating with said cavity and disposed along the length of said cavity, and distinct groups of fluid outlet ducts communicating with said cavity and disposed along the length of said cavity in an interlaced sequence with said groups of fluid inlet ducts, the individual ducts of said groups of inlet ducts are angularly offset with respect to the individual ducts of said groups of outlet ducts, and a group of annular channels formed in the exterior surface of said diffuser, said group of channels being equal in number to the additive number of said groups of inlet ducts and said groups of outlet ducts, each one of said groups of fluid inlet ducts and said groups of fluid outlet ducts communicates with a different one of said channels.
Claim 3
Dependent Claim
38 words
A diffuser according to claim 1 in which said cavity has a substantially cylindrical wall and said individual ducts of both said groups of inlet ducts and said groups of outlet ducts are spaced evenLy around said wall.
Claim 4
Dependent Claim
40 words
A diffuser according to claim 2 in which means are provided at the ends of said cavity both for allowing a solid member to pass through said cavity and for preventing a fluid from exiting said cavity at said ends.
Claim 5
Dependent Claim
49 words
A diffuser according to claim 3 in which said individual ducts of each one of said groups of inlet ducts and said groups of outlet ducts are six in number, said groups of inlet ducts are three in number and said groups of outlet ducts are three in number.
Claim 6
Dependent Claim
27 words
A diffuser according to claim 4 in which said individual ducts are cylindrical and the diameter of said ducts is less than the width of said channels.
Claim 7
Dependent Claim
199 words
A cell, suitable for working upon a solid material passing continuously therethrough, comprising a. a housing having a bore extending therethrough, a group of fluid inlet ports communicating with said bore, and a group of fluid outlet ports communicating with said bore; and b. a fluid diffuser disposed tightly within said bore, said diffuser having an interior lengthwise cavity, distinct groups of fluid inlet ducts communicating with said cavity and disposed along the length of said cavity, distinct groups of fluid outlet ducts communicating with said cavity and disposed along the length of said cavity in an interlaced sequence with said groups of fluid inlet ducts, and a group of angular channels formed in the exterior surface of said diffuser, said group of channels being equal in number to both the additive number of both said groups of inlet and outlet ducts and the additive number of said groups of inlet and outlet ports, said channels are positioned such that each one of said group of inlet ports communicates with a different one of said group of inlet ducts and each one of said group of outlet ports communicates with a different one of said group of outlet ducts.
