Abstract
Abstract An improved metal anode assembly formed as an integral titanium casting which is comprised of a spider-like distributor having an anodic surface secured to the bottom thereof. At least one anode post receiver is formed in the top of the distributor. The active face of the anodic surface is coated with at least one oxide of a platinum group metal. Utilizing cast titanium to form the distributor, the anode post receiver and the anodic surface of the metal anode assembly of this invention simplifies fabrication of the metal anode assembly and improves the durability and stability of the metal anode assembly.

Claim 3
Dependent Claim
105 words
employing as said distributor a spider-like distributor having a plurality of support ribs, 2. employing as said metal anode assembly an integral titanium casting comprised of a. said distributor, b. said anodic surface, c. said anode support receiver, 3. said anodic surface having a first set of two opposite sides longer than the remaining set of two opposite sides, 4. said anodic surface being formed of a series of spaced-apart bars parallel to said first set of opposite sides and 5. said metal anode assembly being adapted for positioning in said cell with said spaced-apart bars parallel to the direction of flow of said brine.
Claim 4
Dependent Claim
105 words
employing as said distributor a spider-like distributor having a plurality of support ribs, 2. employing as said metal anode assembly an integral titanium casting comprised of a. said distributor, b. said anodic surface, c. said anode support receiver, 3. said anodic surface having a first set of two opposite sides longer than the remaining set of two opposite sides, 4. said anodic surface being formed of a series of spaced-apart bars parallel to said first set of opposite sides and 5. said metal anode assembly being adapted for positioning in said cell with said spaced-apart bars parallel to the direction of flow of said brine.
