Abstract
Abstract A self-energizing water treating assembly capable of being either removably disposed in a container through which a stream of water flows or in a tank containing a stationary body of water to render the water slightly alkaline, remove free dissolved oxygen from the water, forms gelatinous thixotropic suspensions that envelops foreign particled material in the water and render the same substantially tasteless and odorless, and minimizes the tendency of minerals in the water being deposited as hard scale on the tubes or containers in which the water is heated or transformed to steam.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
A self energizing water treatment assembly that includes: a. a first generally rectangular copper plate having upper and lower edges and a pair of end edges, with at least one transverse slot that extends upwardly from said lower edge; b. a plurality of generally rectangular second copper plates and magnesium plates that have lower edges from which transverse slots extend upwardly that may be laterally aligned with said slot in said first copper plate; c. a metal electrical conducting bolt having a head and a free threaded end that may be inserted in said slots; d. a plurality of spacers on said bolt that hold said first and second copper plates and magnesium plates in laterally spaced relationship; e. a nut that engages said threads on said bolt, said bolt when tightened holding said assembly together as an integral unit, said nut when loosened permitting a desired one or all of said plates to be lifted from said bolt and replaced by plates that have not been subjected to water.
Claim 2
Dependent Claim
170 words
A self energizing water treatment assembly that includes: a. a first generally rectangular copper plate having upper and lower edges and a pair of end edges, with at least one transverse slot that extends upwardly from said lower edge; b. a plurality of generally rectangular second copper plates and magnesium plates that have lower edges from which transverse slots extend upwardly that may be laterally aligned with said slot in said first copper plate; c. a metal electrical conducting bolt having a head and a free threaded end that may be inserted in said slots; d. a plurality of spacers on said bolt that hold said first and second copper plates and magnesium plates in laterally spaced relationship; e. a nut that engages said threads on said bolt, said bolt when tightened holding said assembly together as an integral unit, said nut when loosened permitting a desired one or all of said plates to be lifted from said bolt and replaced by plates that have not been subjected to water.
Claim 3
Dependent Claim
29 words
An assembly as defined in claim 1 in which f. said first copper plate is of greater length and width than said second copper plates and said magnesium plates.
Claim 4
Dependent Claim
111 words
An assembly as defined in claim 2 which in addition includes: g. a housing assembly formed from a non-electrical conducting material, said assembly including a box having a pair of side walls and end walls and a bottom, a water inlet and outlet in said pair of end walls, longitudinal slots on the inner surface of said pair of end walls, said slots removably engaging marginal edge portions of said first copper plate; a cover mounted on said box, said cover having a longitudinal slot on the inner surface thereof that removably engages a marginal edge portion of said first copper plate; means for removably securing said top to said box.
