Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
225 words
A method for gold plating a metallic surface, the steps comprising: providing a mobile electroplating apparatus having wheels to enable the apparatus to be easily moved by a user to any desired position in relation to a metallic surface to be gold plated, a seat to accommodate a user while electroplating the metallic surface, a DC power source having a plurality of voltage output receptacles, a plurality of chemical solution containers, a workpiece contact member for completing an electric circuit between the metallic surface and the DC power source, and means for sequentially applying chemical solutions in said containers on the metallic surface to be gold plated, said means including a plurality of hand manipulated applicators, each of the applicators connectable by a wire lead to the DC power source through the voltage output receptacles; securing an electrically conductive member on each of the applicators; encasing each of the electrically conductive members in a chemical solution absorbent sleeve; successively and selectively immersing the absorbent sleeves on said electrically conductive members in the chemical solutions; providing power to the DC power source; applying the workpiece contact member to the metallic surface to be gold plated; and applying the chemical solution absorbed on each of the absorbent sleeves on the metallic surface to be gold plated in succession to provide a gold film on said metallic surface.
Claim 2
Independent Claim
225 words
A method for gold plating a metallic surface, the steps comprising: providing a mobile electroplating apparatus having wheels to enable the apparatus to be easily moved by a user to any desired position in relation to a metallic surface to be gold plated, a seat to accommodate a user while electroplating the metallic surface, a DC power source having a plurality of voltage output receptacles, a plurality of chemical solution containers, a workpiece contact member for completing an electric circuit between the metallic surface and the DC power source, and means for sequentially applying chemical solutions in said containers on the metallic surface to be gold plated, said means including a plurality of hand manipulated applicators, each of the applicators connectable by a wire lead to the DC power source through the voltage output receptacles; securing an electrically conductive member on each of the applicators; encasing each of the electrically conductive members in a chemical solution absorbent sleeve; successively and selectively immersing the absorbent sleeves on said electrically conductive members in the chemical solutions; providing power to the DC power source; applying the workpiece contact member to the metallic surface to be gold plated; and applying the chemical solution absorbed on each of the absorbent sleeves on the metallic surface to be gold plated in succession to provide a gold film on said metallic surface.
Claim 3
Dependent Claim
143 words
A method according to claim 1, wherein the metallic surface to be gold plated is first stripped of any metal on which gold cannot be plated by dipping one of the sleeve encased electrically conductive members in a chemical stripping solution and applying it on the metal to be stripped; rinsing the stripping solution from the metallic surface; activating the metal-stripped metallic surface with a second sleeve encased electrically conductive member by dipping the sleeve in a metallic surface activating chemical solution and applying the activating solution to the stripped metal surface to be gold plated; rinsing the activating solution from the metallic surface; applying a gold film on the activating surface by dipping a third sleeve encased electrically conductive member in a chemical solution containing a gold plating compound and applying the solution containing the gold plating compound on the activated surface.
