  • Patent number: 10086219
    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. In some examples, a piston member may provide a movable seal for providing the fluid-communication path and its interruption. An exemplary piston member may be slidably reset in a non-interrupting mode by an adequate primary fluid pressure, and slidably set in an interrupting mode by a user activation. The interrupting mode may silence the whistle which may facilitate user communication during what may be a stressful primary fluid source failure event. Some exemplary automatic fluid alarms may conserve secondary fluid when the whistle is silenced.

  • Patent number: 7565916
    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 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.

    Abstract: A simple, mechanical device is provided which produces an acoustic signal a specified depth. The device consists of a shear plug in an exterior wall of the device housing which prevents the movement of a spring biased piston. The plug is subjected to increasing differential pressure between the exterior and interior of the housing as the depth of the device beneath the water surface increases. 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.

  • Patent number: 5534090
    Abstract: A novel dosimeter capsule for indicating the condition of the solid propellant contained within a rocket motor to provide a measure of the remaining service life of the motor is described, which comprises a sealed expandable container and a portion of the solid propellant sealed therein and sized to fill the available volume within the container, the propellant portion containing a smaller concentration of chemical stabilizer than that which characterizes the solid propellant contained in the rocket motor, so that the propellant portion will deteriorate at a predictably faster rate than the rocket motor propellant, resulting in an increase of pressure within the expandable container of evolved gaseous products of the decomposition of the propellant portion and an accompanying bulge or protrusion of the container from its receptacle on the rocket motor casing corresponding to the increased internal pressure.

  • Patent number: 5226447
    Abstract: A detection system is provided for sensing a malfunction of a valve having an outlet connected to an end of a first pipe through which pressurized fluid may be flowed in a downstream direction away from the valve. The system includes a bypass pipe connected at its opposite ends to the first pipe and operative to bypass a portion of the fluid flow therethrough around a predetermined section thereof. A housing is interiorly divided by a flexible diaphragm into first and second opposite chambers which are respectively communicated with the first pipe section and the bypass pipe, the diaphragm being spring-biased toward the second chamber. The diaphragm housing cooperates with check valves and orifices connected in the two pipes to create and maintain a negative pressure in the first pipe section in response to closure of the valve during pressurized flow through the first pipe. A pressure switch senses the negative pressure and transmits a signal indicative thereof to a computer.
