  • Publication number: 20080092634
    Abstract: A leak monitoring and emergency venting apparatus for a double-walled tank includes a pipe for connecting a space between the walls of the tank to the atmosphere, a plug releasably closing an outer end of the pipe, and a pressure gauge in the plug in fluid communication with the interior of the pipe for monitoring the fluid pressure between the walls of the tank. If the pressure in the space between the walls of the tank rises above a predetermined level, the plug and gauge are discharged from the pipe allowing venting of the space to the atmosphere.

  • Patent number: 7040358
    Abstract: A pressurized fluid filling nozzle provided with a ring for fastening on an adaptor connected to a container and with a controlled valve adapted to selectively control flow of fluid through a conduit. A sensor detects the fastening of the nozzle on the adaptor and makes it possible to render a kinematic link between a control member and the valve active to displace the valve from a position where it obturates the conduit towards a position where it leaves a passage free for fluid flow. The control member is a trigger provided with at least one profiled guide which comprises two parts which cooperate with a guide element of a lever articulated on the valve. Depending on a position of the guide element, a transmission of force between the trigger and the valve is, or is not, possible.

  • Patent number: 6926312
    Abstract: A quick coupler for joining two pipes that includes a male element adapted to be fitted into a female element and maintained in position by a latch forming a stop and opposing withdrawal of the male element. A movable safety member maintains the latch in a blocked position, under the force of pressure of fluid in the coupler, by the cooperation of two surfaces provided, one on the latch and one on the safety member, that are forced into engagement with one another. The safety member releases the latch when a residual pressure in the coupler drops to a safe level.

  • Patent number: 6905151
    Abstract: A quick connect coupling for removably connecting two pipes which comprises a male element adapted to fit into a female element along a principal axis of the coupling. The Female element includes at least one ramp for receiving a radial projection of the male element to lock these elements together. The ramp is formed in a ring freely rotatably mounted in the female element, and fixed in translation along the principal axis, while the projection is fixed with respect to the male element. The ramp forms a seat for locking the radial projection. Locking is obtained by essentially axial movements of the male and female elements with respect to one another.

  • Patent number: 6877778
    Abstract: Linearly actuated quick connect pipe couplings which include a male element and a female element adapted to fit into each other along a principal axis. One of the elements includes at least one ramp for receiving a radial projection mounted to the other element which locks the elements together by axial movement of the elements relative to one another. One of the ramp or the projection is formed with a ring mounted to rotate but is fixed in translation along the principal axis of one of the male or female elements. The ramp forms a first seat for locking the projection when the coupling is in a configuration to permit fluid passage and a second seat, offset axially with respect to the first seat, for locking the projection when the coupling is in a configuration to permit decompression of fluid within the coupling.

  • Patent number: 6814341
    Abstract: A quick connect coupling for removably joining two pipes includes an upstream element and a downstream element adapted to be fitted axially with the upstream element thereby opening a valve movable between a position of opening and a position of closure. The upstream element is provided with at least one O-ring disposed to surround the valve and is adapted for connection to an upstream pipe for inlet of pressurized gas, particularly oxygen. A primary sealing zone is provided upstream of the O-ring which is dimensioned to induce a significant reduction in a flowrate of gas flowing in the direction of the O-ring in order to limit overheating of the O-ring.

  • Publication number: 20030178096
    Abstract: The filling nozzle according to the invention is provided with a ring for fastening on an adaptor connected to a container and with a controlled valve adapted to selectively obturate a conduit for flow of a fluid. A sensor for detecting the fastening of the nozzle on an adaptor makes it possible, as a function of the fastening, to render a kinematic link between a control member and the valve active, this link making it possible, in active configuration, to displace the valve from a position where it obturates the conduit towards a position where it leaves a passage free for the fluid in the conduit. The control member is a trigger provided with a notch which comprises two parts in which may slide an element fast with a lever articulated on the valve. Depending on the part where this element slides, a transmission of effort between the trigger and the lever is, or is not, possible.

  • Patent number: 6589293
    Abstract: The invention relates to the dehairing (depilating) of animal pelts, hides or skins, more specifically to depilatory paint and depilatory paint (depilation paint) thickener used in the depilation process in for example fellmongeries. The invention provides a depilatory paint thickener comprising a starch containing essentially only amylopectin molecules. Such thickener, is among other things, easily soluble in cold water; improves diffusion of chemicals (like sulfide or lime) throughout the skin; improves viscosity or resistance to shear of a paint, whereby less starch is needed to exert a similar effect; and increases the suspendability of a lime, allowing less time to be used which creates environmental advantages in waste disposal.

  • Patent number: 6412828
    Abstract: A quick safety connection for the removable joining of pipes, comprising a male connector and a female element adapted to fit and to be locked inside one another. A controlled locking mechanism is adapted to immobilized the male connector axially in a position of connection, while at least one retention member is provided to immobilize the male connector, after release of the connector by said locking mechanism, in an intermediate position of discharge of the pipe connection. The locking mechanism and retention member are controlled by a sleeve sliding around the female element. Vents and safety stops are provided to limit the movement of the sleeve under the effect of the pressure prevailing due to the discharge of the connection in the intermediate position between the female element and the sleeve.

  • Patent number: 6176263
    Abstract: This invention relates to a circuit breaker for an installation handling pressurized fluid comprising an internal valve, at least one joint of substanially toroidal shape being disposed in an accommodating housing around said valve and/or a member for maneuvering the valve, characterized in that the housing is connected, via at least one fluid-circulation channel, to a counter-pressure zone formed downstream of the joint around the valve or the maneuvering member. During a transitory phase of opening of the valve, a preferential flow circuit of the fluid is arranged between the housing and the counter-pressure zone through the channel. Thanks to the counter-pressure exerted on the seal, the latter does risk being dislocated with respect to its housing.
