Abstract: An apparatus, system, and method for the secure attachment and restraint of a pipe end within a fitting is disclosed. The invention includes a mechanical restraint apparatus that is integral and monolithic with the flange of a bell of a spigot-and-bell joint architecture, along with one or more internally disposed grooves within the bell that receive a circumferential gasket, in order to maintain a seal about the pipe end when it is inserted into the bell. The inventive apparatus combines features of mechanical connections and push-on connections.

Abstract: Visually simulated tooth braces include individual visual tooth brace indicia to simulate real functional braces commonly worn by children and adults alike to adjust human teeth. The visually simulated tooth braces allow for children to temporarily wear braces as many of their classmates, friends, and siblings do.

Abstract: In a poultry watering system having a float-controlled valve for maintaining a desired water level in a trough, leakage through the valve from an overhead supply line, which may occur when the water supply is cut off is effectively prevented without reducing sensitivity of the float by the provision of spring means located within the interior of a valve housing and acting on the end of the float stem.
