Abstract: A water softening system and apparatus utilizes two tanks, one for service and one for regeneration, and a control system operated by soft water flow controls the operation of all valves and the sequences of regeneration. The control system utilizes parallel plate valves for switching from one tank to the next, parallel plate valves energizing the piston moving the switching valves, and a parallel plate valve structure for distributing the regeneration water, as to amount of flow, direction and timing. A two-way to one-way cam structure initiates the operation of a control cylinder which supplies soft water to the metering valve and the regeneration valve as and where needed.

Abstract: The disclosure teaches a novel foundation clip assembly comprising a foundation clip having a web and two upturned ends integral with said web in combination with a sleeve means covering a central part of the web. Also, a novel method of constructing a foundation stem on a footing is taught which comprises the steps of providing foundation clips and sleeves; inserting the clips in the sleeves; positioning the clips and sleeves on the footing to receive concrete forms; inserting concrete forms in the clips; pouring the concrete in the forms; removing the forms when the concrete sets up; and finally removing said clips from said sleeves for further use.
