Abstract: Apparatus and associated methods relate to an automatic fluid alarm that provides a fluid-communication path between a secondary fluid source and a whistle port when a primary fluid source experiences a reduction in pressure, the automatic fluid alarm being user resettable by disconnecting the primary fluid source or otherwise reducing the primary source pressure and activating a reset member, thereby interrupting the fluid-communication path.

Abstract: The pneumatic oscillating valve includes a housing defining an internal chamber, an inlet passageway, and an outlet passageway. An annular seat extends into the internal chamber. A diaphragm is disposed in the internal chamber. The diaphragm seats against the annular seat and separates the inlet passageway from the outlet passageway. A spring engages the diaphragm to seat the diaphragm against the annular seat. As fluid is admitted to the inlet passageway, pressure increases in the inlet passageway until sufficient pressure is present to overcome the spring and unseat the diaphragm. The inlet passageway is more restrictive to fluid flow than the outlet passageway such that fluid is exhausted more quickly from the outlet passageway than can pass through the inlet passageway allowing pressure in the inlet passageway to reduce to a point less than the spring force of the spring thereby allowing the diaphragm to reseat on the seat.

Abstract: A gas regulator/valve device particularly for use in emergency escape breathing apparatus, and comprising a T-shaped regulator piston which is movable in a stepped bore and has a nylon seat for closing a jet which receives the input (high pressure) gas. Movement of the piston by the input gas from a cylinder (not shown) is balanced by a spring.

Abstract: A simple mechanical device is provided which generates acoustic signals at ne or more specified depths. The device consists of a spring loaded piston placed in a wall of a housing, the spring loading biasing the piston away from the housing. The piston is subjected to a pressure differential between the exterior and interior of the housing such that the piston moves against the spring force and into the housing as the pressure differential, corresponding to a depth of the housing beneath a water surface, increases. As the piston moves further into the housing, it contacts a series of latches, each latch being used to detain spring loaded striker. The latches are spaced along the travel path of the piston such that each striker is associated with a specific piston movement, or depth. When the piston contacts a latch, the striker is released and strikes against a ledge within the housing, creating one of the acoustic signals.

At a known pressure differential, corresponding to a specified depth, the shear plug fails, allowing for the actuation of the piston. The spring biased piston strikes against a ledge in the device, creating the acoustic signal.
