Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
18 words
The bath of claim 1 wherein the particles range in size from about 0.005 to about 50 microns.
Claim 2
Dependent Claim
43 words
A process for suppressing mist formation in a chromium electroplating bath solution which comprises incorporating therein an effective spray suppressing amount of polyethylene particles having a particle size ranging from 0.002 to about 100 microns wherein the particles float on the electroplating bath.
Claim 3
Dependent Claim
18 words
The process of claim 3 wherein the particles range in size from about 0.005 to about 50 microns.
Claim 4
Independent Claim
19 words
The method of claim No. 5 wherein the particles range in size from about 1 to about 30 microns.
Claim 5
Dependent Claim
74 words
A process for suppressing the production of fumes and mist from a chromium electroplating bath composition which comprises passing current from an anode to a metal cathode through an aqueous electroplating bath solution containing a chromium metal compound providing chromium metal ions for electroplating metal and including an effective spray suppressing amount of polyethylene particles having a particle size of 0.002 to about 100 microns wherein the particles float on the electroplating bath solution.
Claim 6
Dependent Claim
18 words
The process of claim 6 wherein the particles range in size from about 0.005 to about 50 microns.
