    Abstract: A housing containing a rotatable cage for rotatably supporting a spherical flow control valve having a vertically orientated open or filled conduit and an internal bottom weight mass centered on the vertical conduit. If the rotatable cage is tilted, the gravity-responsive bottom weight mass rotatably maintains the control valve conduit in a vertical orientation. If the cage is walled, the rotating cage wall will travel over the ends of an open conduit to form a seal, which effectively occludes any gas, liquid or electromagnetic beam flowing through the conduit. If the cage is open and rotatably supports the valve via annular supports, the rotating cage will interrupt an electromagnetic beam or electric current flow through the control valve conduit. The flow control valve may also have an extended open or filled conduit which may be provided with an additional weight mass, or a magnetic mass associated with a locking ring.

  • Patent number: 6904943
    Abstract: A vent system associated with a vapor outlet is coupled to a container (e.g., a fuel tank). The vent system can be used for onboard refueling vapor recovery (ORVR) for vehicles. The vent system includes a first elongated member (e.g., a vent tube), a rotating device, and a second elongated member (e.g., a breather tube) that is coupled between the rotating device and a buoyant device. The buoyant device interacts with materials (e.g., fuel) input into the fuel tank to actuate rotation of the rotating device. Once a predetermined amount of fuel has been input into the fuel tank, the buoyant device rotates the rotating device a predetermined amount, which stops venting of fuel vapor through the vent system. The fuel level continues to increase up the filler pipe until an automatic shut off mechanism of the device controlling fuel input stops fuel flow.

  • Patent number: 6701223
    Abstract: Pipelines are controlled by specifying operations along them. Control specifies sequential control values defining operations at each station to control the pipeline state. The time-dependent state is determinable by software calculations using continuous measurements along the pipeline. Forecasted deliveries dictate that the current pipeline state must change by future time (T). Control sequences are determined at pipeline stations to exercise optimum pipeline control while achieving predetermined goals from the current state to a sustainable target state which supports future deliveries by simulating current pipeline states through time interval T, while satisfying time-dependent forecast deliveries. An initial computable control set is iteratively improved and evaluated by computing the gradient of pipeline operational cost, costs of missing target(s), and costs of violating constraints by solving an adjoint problem each time the simulation is made.

The spool also has a non-blocking position in which the spool allows transmission of combustion products from the microdet to the pyrotechnic transmission line to ignite the pyrotechnic transmission line. The movement of the spool from the blocking position to the non-blocking position is controlled so that it moves only in the event of vehicle deceleration above a predetermined rate.

  • Patent number: 5154442
    Abstract: A damper for a vehicle suspension utilizes accelerometer elements for controlling damping rate in response to lateral or longitudinal ("horizontal") acceleration of the vehicle. The accelerometer can be a mass/spring assembly within the damper housing. The accelerometer is linked to at least one damping rate adjuster element, such as a variable orifice or pop-off valve, so that increasing displacement of the accelerometer, in response to increasing vehicle horizontal acceleration, varies the setting of the rate-controlling elements to modify the damping rate. The horizontal acceleration/damping curve can be "tuned," and can be varied in X and Y axes, by selecting various accelerometer weights and springs, or by utilizing multiple accelerometers.

  • Patent number: 4960147
    Abstract: This disclosure is directed to a vibration or shock-activated valve. A valve mounted for rotation in a gas line or the like is connected to an elongate handle by a valve stem. The valve is spring activated to rotate from an open to a closed position. The elongate handle engages and is retrained by a ball detent. The ball detent has a ball supported on the engagement end of a conical end of a pendulum member. When vibration or shock moves the pendulum, the ball falls, releasing the elongate handle permitting the spring loaded valve to rotate from the open to the closed postion. A handle stop at 90.degree. stops the valve in the closed position.

  • Patent number: 4860780
    Abstract: A vibration activated device is provided for closing a utility gas valve. A control lever on the valve is held in the open position by a latch which fits into a latch groove in the end of the control lever of the valve; a spring is attached to the control lever to pull the valve shut when the latch is released. The shock waves of the earthquake move a pendulum which then moves an activator which then moves a pivot arm which moves a latch located thereon to release the valve control lever. When the valve control lever is released, a spring pulls the end of the valve control lever to turn it to the closed position. The device is designed to operate on a valve located in either a vertical or a horizontal pipeline.

  • Patent number: 4756328
    Abstract: A fuel tank protection valve includes a pendulum type weight that hangs within a bearing socket located below the vent line opening in a fuel tank vapor collection dome. When the vehicle tilts significantly from the horizontal, the weight pivots within the socket, kicking a float ball up to seal the vent line opening. The closing angle of the valve may be easily varied, without changing the shape or size of the bearing socket, by varying the offset from the socket pivot point of the bearing socket of an extension of the weight that actually engages the float ball.

    Abstract: An automatic valve motor for shutting off utilities, such as gas, in the event of an earthquake. The valve motor is self-contained and can be mounted by unskilled persons on a conventional residential gas installation adjacent the main valve without modifying the valve or interfering with the operation of the gas line. An omnidirectionally movable pendulum acting on a pivotal latch is used to release for rotation a wheel whose hub has a key slot which engages the actuator bar of the gas valve. The wheel is driven by a linear spring arrangement which exerts a generally tangential turning force on the wheel for maximum leverage throughout an arc of rotation of about 90.degree..

  • Patent number: 4469116
    Abstract: A valve device serving to prevent overfilling of portable containers, particularly liquid gas cylinders, includes a ball which is freely rotatable relative to a spherical seating face in a casing having a filling channel extending to said seating face. The ball has a passage which in the prescribed filling position communicates with the channel, and the ball is through a rod and a flexible link connected to a load member. As long as this load member is above the liquid level, it tends to keep the ball, and thus its passage in a given orientation so that the communication is broken if the container is tilted away from the prescribed filling position.When the liquid level has reached a predetermined height, the load member acts as a float so as to interrupt the filling operation by causing the ball to change its orientation.
