Abstract: A baby bottle with two open ends and two end caps for securing a nipple and a pressure relief valve assembly to the ends of the bottle. The valve assembly includes an outwardly flanged inverted cup-shaped valve seat member having a base provided with an axial bore which extends from the inner to the outer face of the base and accommodates a reciprocally axially movable valve stem. The valve stem at one end thereof defines a valve head normally received in the valve seat-defining end region of the bore under the biasing force of a spring interposed between the inner face of the base and a snap-on disc carried by the valve stem.

Abstract: An automatic shut-off valve arrangement for a fire sprinkler system includes a set of auxiliary pipe fittings interconnected between the water distribution pipes and the sprinkler heads. Each fitting houses a multi-vane paddle wheel rotatably mounted under an eccentric valve opening normally unobstructed by a movable valve member, and the paddle wheel axle is connected by a gear train to an actuator for the valve member. When water flows from the distribution pipe through the fitting and exits therefrom via the sprinkler head to douse a fire, the paddle wheel rotates rapidly and drives the actuator via the gear train so that the valve member is shifted to close the valve opening and interrupt the flow of water therethrough after a prescribed time interval, thereby minimizing the risk of water damage to the protected premises.
