Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
A method of making capacitor anodes comprising providing a mold having cavities therein which have been filled with a slurry of film-forming metal, moving headed or barbed ends of risers made of film-forming metal into the cavities, freezing slurry around ends of the risers while maintaining the ends in the cavities to form shaped masses, removing the shaped masses from the cavities, sintering the shaped masses at an elevated temperature to form rigid bodies, and forming a dielectric oxide over the rigid bodies.
Claim 2
Independent Claim
83 words
A method of making capacitor anodes comprising providing a mold having cavities therein which have been filled with a slurry of film-forming metal, moving headed or barbed ends of risers made of film-forming metal into the cavities, freezing slurry around ends of the risers while maintaining the ends in the cavities to form shaped masses, removing the shaped masses from the cavities, sintering the shaped masses at an elevated temperature to form rigid bodies, and forming a dielectric oxide over the rigid bodies.
Claim 3
Dependent Claim
49 words
A method according to claim 1 wherein said anodes are placed in a container and which an electrolyte is contained therein and which electrolyte engages a portion of the dielectric oxide on said anode and wherein said electrolyte also is in contact with a cathotic portion of said container.
Claim 4
Dependent Claim
13 words
A method according to claim 2 wherein said electrolyte is a wet electrolyte.
Claim 5
Dependent Claim
13 words
A method according to claim 2 wherein said electrolyte is a solid electrolyte.
Claim 6
Dependent Claim
12 words
A method according to claim 4 wherein said electrolyte is manganese dioxide.
Claim 7
Dependent Claim
90 words
In a method of making a body suitable for use as an anode in a capacitor, the steps of shaping a mass including film-forming metal powder and a freezable bonding agent around a headed or barbed portion of an anode riser, freezing the bonding agent to bond powder together around the headed or barbed portion of the anode riser to provide a shaped mass, sintering the shaped mass to form a rigid body including the anode riser, and forming a dielectric oxide film of the film-forming metal over the body.
Claim 8
Dependent Claim
90 words
In a method of making a body suitable for use as an anode in a capacitor, the steps of shaping a mass including film-forming metal powder and a freezable bonding agent around a headed or barbed portion of an anode riser, freezing the bonding agent to bond powder together around the headed or barbed portion of the anode riser to provide a shaped mass, sintering the shaped mass to form a rigid body including the anode riser, and forming a dielectric oxide film of the film-forming metal over the body.
Claim 9
Dependent Claim
42 words
The method of claim 6, wherein the film-forming metal powder is selected from the group consisting of Al, Ta, Ti and Nb, wherein the anode riser is of the same material as the powder, and wherein the freezable bonding agent includes water.
Claim 10
Dependent Claim
28 words
The method of claim 6, including the further steps of contacting the dielectric oxide film of the body with an electrolyte, and contacting the electrolyte with a cathode.
Claim 11
Dependent Claim
25 words
The method of claim 8, wherein the electrolyte is selected from the group consisting of wet and solid electrolytes, and the cathode is a container.
