A method of upgrading a below grade fill to prevent accidental release harmful materials from contaminating the soil below grade.

Beverage fill valves, adapter nozzles for placement at the discharge end of beverage fill valves, novel counterpressure, and snift discharge valves including plungers, actuators or buttons, and unique counterpressure snift flow paths in novel combination with fill valves and/or fill valves with adapter nozzles, and related methods are disclosed, whereby automatic filling of a can having a smaller diametral opening at the top thereof is accommodated.

An improved float assembly for a dishwasher liquid fill system includes cam means on the float stem. The cam includes a first portion operative, upon the liquid rising to its normal fill level, to maintain a switch in its circuit closing position allowing the fill valve to be opened at selected intervals during the operational cycle. Upon the float being buoyed upwardly by the liquid level rising above its normal-fill level to an over-fill level the cam means is operative to retain the float at ...

A fill and vent valve assembly has a bore in a first member and a cylindrical stem of a second member positioned within the bore. A blind bore extends inwardly from an inner end of the stem and has an internal threaded section. First and second passages in the stem communicate the blind bore with a passage device which communicates the bore of the first member with a fluid chamber. A fill valve has an external threaded section threaded into the internal threaded section of the stem and is movabl...

A dishwasher fill system providing a combination fill control system and timer fill sequence that assures a predetermined minimum quantity of water is present in the dishwashing chamber regardless of the water fill flow rate and the household waterline pressure. The system provides two assured fill levels with a predetermined minimum water level fill cycle portion for a rinse fill and an increased minimum level fill cycle portion for a wash fill. If the rinse fill water level is below its minimu...

The automatic fill-stop valve passes the liquid filling a tank. A level-sensing tube passes vapor until the tank liquid level rises that high, and, thereupon, passes liquid. Serial orifices in the sensing passage produce a valve closing signal when the liquid level reaches the sensing tube to automatically stop the filling of the tank.

A cooling tower has a plurality of cooling regions with each cooling region being constructed in a cross flow or counter flow configuration for allowing air to pass into the path of falling water within that region. Each region contains a fill bundle composed of twisted fill elements. Each fill element consists of an elongated substantially flat member which is twisted normally about its longitudinal axis. A plurality of the fill elements are connected in rows and placed in the path of the air c...

A photographic camera control system is provided for varying the time at which a source of artificial illumination is energized subsequent to the commencement of a photographic exposure interval in accordance with variations in the ambient scene light intensity and the camera-to-subject range. The control system operates to energize the source of artificial illumination at later times and hence larger aperture values under conditions of insignificant ambient scene light intensity than under cond...

The invention relates to an improved U-shaped splash bar fill configuration for use in crossflow cooling towers.

Cooling tower splash fill batts are supported by a plurality of vertically and horizontally aligned grids made from vertical and horizontal wire strands. The grids occupying the same vertical plane are connected to each other by elongated generally C-shaped fill hanger splice beams.
