Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A retaining and restraining support structure for a plural cell electrolyzer, comprising: (a) a sleeper assembly for supporting an electrolyzer cell vertically beneath the longitudinal dimension thereof; (b) retaining support means for applying a longitudinal compressive force on the individual cells constituting said electrolyzer cell, comprising: (i) terminal electrolyzer cell end frames; (ii) a plurality of adjustable, longitudinal tension bars disposed between said end frames; and, (c) restraining support means for applying an oblique stabilizing force on said electrolyzer cell for maintaining the individual cells constituting the same in substantially vertical orientation, said restraining support means including adjustable, diagonal tie bar means extending from one of said end frames to a horizontally displaced anchor point.
Claim 2
Dependent Claim
115 words
A retaining and restraining support structure for a plural cell electrolyzer, comprising: (a) a sleeper assembly for supporting an electrolyzer cell vertically beneath the longitudinal dimension thereof; (b) retaining support means for applying a longitudinal compressive force on the individual cells constituting said electrolyzer cell, comprising: (i) terminal electrolyzer cell end frames; (ii) a plurality of adjustable, longitudinal tension bars disposed between said end frames; and, (c) restraining support means for applying an oblique stabilizing force on said electrolyzer cell for maintaining the individual cells constituting the same in substantially vertical orientation, said restraining support means including adjustable, diagonal tie bar means extending from one of said end frames to a horizontally displaced anchor point.
Claim 3
Dependent Claim
19 words
The electrolyzer support of claim 1, wherein said diagonal tie bar means comprise a pair of adjustable tie bars.
Claim 4
Dependent Claim
19 words
