Abstract: A toilet having a water inlet valve apparatus has a flush tank with a water inlet tube connecting from a water source into the flush tank. A water cutoff is attached to the water inlet tube and has a valve seat in a floating valve element positioned in the water inlet tube to seat in the valve seat responsive to water in the water inlet tube so that the water is cut off from entering the toilet tank when the valve element is seated in the valve seat. A removably attached ballcock valve assembly is removably attached to the water cutoff valve and water inlet tube and has a valve opening member positioned to hold the floating valve element in the water cutoff valve from the valve seat when the ballcock valve is attached to the water cutoff valve. Removing the ballcock valve from the water cutoff valve closes the water cutoff valve and stops the flow of water into the tank from the water inlet tube.

Abstract: A part number slide rule apparatus for displaying a company part number by the position of a plurality of slide members relative to a body member has a body member supporting a plurality of sliding slide members therein. The body member has a plurality of elongated openings therein each having indicia thereon indicative of a gauge feature and also having a plurality of part number openings. A plurality of slide members are slidably mounted in the body member and each slide member has a pointer thereon in a predetermined position and a plurality of part number indicia portions positioned thereon, each part number indicia portion being alignable with one of the body member part number openings in the body member when the slide member pointer is positioned to point at selected indicia on the body member indicative of a feature of a gauge.
