Abstract
Abstract Anchoring for a conductive bar in a groove in an electrode block, whereby in the space between the walls of the bar and the groove a cast iron mantle around the bar is provided. In each side wall of the groove at least one recess is provided for the anchoring of at least one projection of the cast iron mantle surrounding the bar.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
92 words
An anchoring arrangement for a conductor bar in an electrode block, said conductor bar being provided with a cast iron mantle, said electrode block defining a groove operable for receiving said conductor bar and said mantle, at least one lateral projection provided on said mantle and at least one recess defined in a sidewall of said groove into which said projection projects, whereby said cast iron mantle and therefore said conductor bar is anchored in said groove to restrain removal in an upright direction of said conductor bar from said electrode block.
Claim 2
Dependent Claim
92 words
An anchoring arrangement for a conductor bar in an electrode block, said conductor bar being provided with a cast iron mantle, said electrode block defining a groove operable for receiving said conductor bar and said mantle, at least one lateral projection provided on said mantle and at least one recess defined in a sidewall of said groove into which said projection projects, whereby said cast iron mantle and therefore said conductor bar is anchored in said groove to restrain removal in an upright direction of said conductor bar from said electrode block.
Claim 3
Dependent Claim
24 words
Anchoring arrangement according to claim 1, wherein said recess comprises an upper and a lower surface, said surfaces being arranged parallel to one another.
Claim 4
Dependent Claim
27 words
Anchoring arrangement according to claim 1 wherein said recess comprises an upper and a lower surface, said surfaces being slightly divergent in the direction of the bar.
