- 9. The method of claim 5 wherein the bosses are made from the group of materials selected from the group consisting of iron, grey iron and malleable iron, ductile iron, steel, stainless steel, molybdenum, nickel, aluminum, copper, molybdenum, magnesium, lead, alloys of each and alloys thereof.
- 10. A method for making an electrolytic unit having
- a substantially planar central support element;
- a plurality of bosses on each side of the central support element projecting outwardly from and contacting the central support element; and
- a peripheral flange structure composed of at least one piece and having an internal surface which sealably receives all external peripheral edges of the central support element;
- said method comprising:
- (a) forming a unitized, planar subassembly of the central support element, at least a portion of the peripheral flange structures and at least a portion of the bosses;
- (b) attaching, by welding, any remaining peripheral flange structures and any remaining bosses to complete the peripheral flange structure desired for at least one side of the central support element;
- (c) covering at least a portion of at least one of the boss-containing sides of the central support element with a metal liner composed of one or more pieces; and
- (d) attaching said metal liner(s) to at least a portion of the bosses contacting the metal liner.
- 11. The method of claim 10 wherein the liner is attached to the ends of at least a portion of the bosses by welding or diffusion bonding.
- 12. The method of claim 10 wherein the metal liner is attached to all of the ends of the bosses by welding or diffusion bonding.
- 13. The method of claim 5 wherein the central support element is made from the group of materials selected from the group consisting of iron, grey iron and malleable iron, ductile iron, steel, stainless steel, nickel, aluminum, molybdenum, copper, magnesium, lead, alloys of each and alloys thereof.
- 14. The method of claim 10 wherein the bosses are made from the group of materials selected from the group consisting of iron, grey iron and malleable iron, ductile iron, steel, stainless steel, molybdenum, nickel, aluminum, copper, molybdenum, magnesium, lead, alloys of each and alloys thereof.
- 15. A method for making an electrolytic unit having
- a substantially planar central support element;
- a plurality of bosses on each side of the central support element projecting outward from the central support element and positioned between, and contacting, the central support element; and
- a peripheral flange structure composed of at least one piece and having an internal surface which sealably receives all external peripheral edges of the central support element;
- said method comprising:
- (a) forming, by casting, die casting, powdered metal pressing and sintering, hot isostatic pressing, hot forging or cold forging, a unitized, planar subassembly of a portion of the central support element, at least a portion of the peripheral flange structures and at least a portion of the bosses;
- (b) forming, by casting, die casting, powdered metal pressing and sintering, hot isostatic pressing, hot forging or cold forging, a unitized, planar subassembly of the remaining portion of the central support element, at least a portion of the peripheral flange structures and at least a portion of the bosses;
- (c) connecting the central support elements;
- (d) attaching any remaining peripheral flange structures and any remaining bosses to complete the peripheral flange structure desired for at least one side of the central support element;
