Abstract
Abstract The combination of a reservoir containing a fluid and applicator means for applying the fluid to means carrying a plurality of pellets to be used as capacitors. The applicator means includes upper and lower walls connected by a rear wall so as to form a slot having a determined length and width. A channel is formed in one of the walls so as to couple the slot to the fluid containing reservoir allowing fluid to flow to the slot in a controlled manner. The applicator means applies determined amounts of the fluid to the means carrying said pellets and the pellets passing therethrough.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A method of applying a fluid to strip means carrying a pellet for use as a capacitor anode, comprising the steps of, depositing a moistened mass of film-forming metallic powder on strip means of film-forming metal, forming the moistened mass to provide a porous pellet joined to the metal strip means, passing the portion of the metal strip means carrying the pellet joined thereto through slot means formed in slot applicator means, the slot means of determined length and width, and contacting the portion of the metal strip means and the pellet passing through the slot with liquid retained in the slot due to the surface tension of the liquid and the geometry of the slot.
Claim 2
Independent Claim
116 words
A method of applying a fluid to strip means carrying a pellet for use as a capacitor anode, comprising the steps of, depositing a moistened mass of film-forming metallic powder on strip means of film-forming metal, forming the moistened mass to provide a porous pellet joined to the metal strip means, passing the portion of the metal strip means carrying the pellet joined thereto through slot means formed in slot applicator means, the slot means of determined length and width, and contacting the portion of the metal strip means and the pellet passing through the slot with liquid retained in the slot due to the surface tension of the liquid and the geometry of the slot.
Claim 3
Dependent Claim
29 words
The method of claim 1, wherein said slot has an upper wall, lower wall and an end wall retaining said upper wall and said lower wall in spaced relationship.
Claim 4
Dependent Claim
34 words
The method of claim 1, wherein the porous pellet joined to The metal strip means is formed by sintering the metallic powder in situ to form a porous pellet joined to the metal strip.
Claim 5
Dependent Claim
32 words
The method of claim 1, wherein the liquid contacting the pellet and the strip is selected from the group including manganous nitrate, a colloidal dispersion of graphite in water or silver paint.
Claim 6
Dependent Claim
29 words
The method of claim 4, wherein the film-forming metallic powder and the strip means of film-forming metal are selected from the group including tantalum, zirconium, aluminum, niobium and titanium.
Claim 7
Dependent Claim
19 words
The method of claim 5, wherein the film-forming metallic powder and the strip means of film-forming metal are tantalum.
Claim 8
Dependent Claim
59 words
The method of claim 1, including the further steps of, subsequent to contacting the metal strip means and pellet with the liquid, providing a second slot means, passing the liquid contacted metal strip means and pellet through the slot of the second slot means and monitoring the electrical characteristics of the metal strip means and pellet in the slot.
Claim 9
Dependent Claim
48 words
The method of claim 1 including the further step of, subsequent to contacting the metal strip means and pellet with the liquid, removing unjoined metallic powder and excess liquid by moving fluid in a direction different from the direction of movement of the metal strip means and pellet.
Claim 10
Dependent Claim
39 words
A method of making a capacitor using the anode of claim 1, comprising contacting the metal strip means and the pellet with dielectric means, contacting the dielectric means with electrolyte means, and contacting the electrolyte means with cathode means.
