Abstract
Abstract A device for eliminating mineral precipitation within a liquid system. A container having inlet and outlet pipes is connectable to external plumbing to receive and pass through the container untreated water or liquid. The inlet pipe is connected within the container to a fitting having a treatment pipe extending therebeneath to the bottom of the container. A metal treatment bar is suspendedly positioned within the treatment pipe, but is spaced internally therefrom to allow the untreated water to contact and pass over the treatment bar eventually emptying into the container. The water exiting the treatment pipe eventually exits the container through the outlet pipe. The treatment bar is fixedly and suspendedly mounted by a rod extending out of the container and secured to a plug sealingly, but removably mounted to the container top wall. The plug is removable along with rod and treatment bar to facilitate cleaning of the bar. A pressure relief valve is mounted to the container top wall to allow for manual release of pressure. Valves are provided on the inlet and outlet pipes in conjunction with a by-pass valve extending therebetween to prevent flow of liquid to the container when the treatment bar is removed for cleaning.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
273 words
Apparatus for stabilizing water comprising: a container for holding water and having an inlet for receiving untreated water and an outlet through which treated water may flow from said container: inlet pipe means mounted to said inlet and extending into said container with said inlet pipe means having a bottom end; outlet pipe means mounted to said outlet; sleeve means mounted to and sealingly extending out of said container at a location separate from said inlet pipe means and said outlet pipe means, said sleeve means having a removable external cap; and, treatment means suspendedly mounted in said container having a conduit connected to said bottom end of said inlet pipe means to receive said untreated water therefrom and further including a metal treatment member removable through said sleeve means once said cap is removed, said conduit circumferentially surrounding said metal treatment member with said member having surfaces exposed to said untreated water passing through said conduit, and wherein; said conduit is suspendedly mounted within said container and is in liquid communication with said inlet pipe means to receive all of said untreated water therefrom, said metal member is located within said conduit and has a plurality of longitudinally extending edges in contact with said conduit forming a plurality of separate passages between said metal member and said conduit extending the length of said metal member and through which said untreated water passes contacting said metal member prior to exiting said conduit into said container, all of said untreated water being adapted to contact said metal member and flow in one direction along the entire length thereof prior to release into said container.
Claim 2
Dependent Claim
273 words
Apparatus for stabilizing water comprising: a container for holding water and having an inlet for receiving untreated water and an outlet through which treated water may flow from said container: inlet pipe means mounted to said inlet and extending into said container with said inlet pipe means having a bottom end; outlet pipe means mounted to said outlet; sleeve means mounted to and sealingly extending out of said container at a location separate from said inlet pipe means and said outlet pipe means, said sleeve means having a removable external cap; and, treatment means suspendedly mounted in said container having a conduit connected to said bottom end of said inlet pipe means to receive said untreated water therefrom and further including a metal treatment member removable through said sleeve means once said cap is removed, said conduit circumferentially surrounding said metal treatment member with said member having surfaces exposed to said untreated water passing through said conduit, and wherein; said conduit is suspendedly mounted within said container and is in liquid communication with said inlet pipe means to receive all of said untreated water therefrom, said metal member is located within said conduit and has a plurality of longitudinally extending edges in contact with said conduit forming a plurality of separate passages between said metal member and said conduit extending the length of said metal member and through which said untreated water passes contacting said metal member prior to exiting said conduit into said container, all of said untreated water being adapted to contact said metal member and flow in one direction along the entire length thereof prior to release into said container.
Claim 3
Dependent Claim
83 words
The apparatus of claim 1 and further comprising: brass extension means fixedly fastened between said cap and said metal member allowing removal of said extension means and said member for cleaning when said cap is removed from said container, said metal member having a top end connected to said brass extension means with said top end positioned beneath said bottom end of said inlet pipe means to allow all of said untreated water to contact said metal bar along the entire length thereof.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2 wherein said metal member is an alloy including copper, tin, iron, lead, zinc and nickel.
Claim 5
Dependent Claim
90 words
The apparatus of claim 3 and further comprising: manually operable pressure relief means mounted to said container at a location separate from said inlet pipe means, said outlet pipe means and said sleeve means and operable to release liquid pressure within said container prior to removal of said metal member; and, valve means connected to said inlet pipe means and said outlet pipe means being operable to limit liquid flow into and out of said container and to by-pass liquid flow around said container prior to removal of said member.
Claim 6
Dependent Claim
63 words
The apparatus of claim 4 and further comprising: a T-shaped fitting coupling said inlet pipe means with said treatment means to route all of said untreated liquid to said metal member and being connected to and between said sleeve means and said conduit with said extension means and said member being movable though said T-shaped fitting upon removal and re-installation of said cap.
