  • Publication number: 20240121541
    Abstract: An electronic device can include a housing, an audio component, and a gasket. The housing can define a first internal volume and the audio component can define a second internal volume. The audio component can include membrane and a venting element having a fluid impermeable layer. The venting element can define a fluid path placing the first internal volume and the second internal volume in fluid communication. At least a portion of the fluid path can extend parallel to the fluid impermeable layer. The gasket can define a seal between the first internal volume and an ambient environment adjacent the housing.

  • Patent number: 11951582
    Abstract: A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material incudes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

  • Patent number: 8826929
    Abstract: A tapping tee assembly and method is provided for fluidly connecting to a conduit. The tapping tee assembly includes a body having a conduit recess for receiving the conduit and further defining a passage having one end adjacent the conduit recess. A cutter is received in the passage and engages a threaded region of the passage for selective advancement and retraction within the passage upon rotation relative the body. The cutter comprises a first component with first and second ends and having a cutting edge at the first end for cutting through a side wall of the conduit to establish fluid communication between the main passage and the conduit. A second component is secured to the first component at the second end either by mechanically securing or molding the second component to the first component.

  • Patent number: 7178544
    Abstract: A valve operable with an associated fluid delivery system having fluid flow therethrough includes a housing, a valve body and a resetable excess flow valve. The housing has a first passage and the valve body is disposed along the first passage and including a wall at least partially defining a second passage. The excess flow valve is supported along one of the first and second passages. The valve body is displaceable between a first position permitting flow through the second passage and a second position substantially shutting-off fluid flow and resetting the excess flow valve.

  • Patent number: 7021328
    Abstract: A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee. All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees.

  • Patent number: 6932389
    Abstract: A connector adapted for use with an associated fluid line includes a connector body having a passage dimensioned to receive the associated fluid line and a capturing member supported on said connector body. The capturing member is suitable for retaining the associated fluid line in the passage. A sealing member is disposed within the passage and is suitable for forming a fluid-tight seal between the connector body and the associated fluid line. A stiffening member is disposed within the connector body along the passage, and an indicator is disposed within the connector body and is adapted to indicate that the associated fluid line has been received a predetermined distance into the passage.

  • Patent number: 6565125
    Abstract: A coupling body has: (i) a central member; (ii) a first retaining member; and, (iii) a second retaining member. The first retaining member and the central member define a first pipe receiving region. The second retaining member and the central member define a second pipe receiving region having a tapered inner surface. A selectively constrictable clamp collar is located in the first pipe receiving region. A bolt or other actuation member is operably engaged with the clamp collar and is movable to constrict the clamp collar. A gripping collet is located in the second pipe receiving region and includes a tapered outer surface. At least one tie-bolt or other fastener extends between the retaining members and is selectively adjustable to draw the first and second retaining members toward each other so that the tapered inner surface engages the tapered outer surface of the collet to constrict the collet radially.

  • Publication number: 20030007362
    Abstract: A vehicle side mirror assembly including a lighted turn signal indicator. The side mirror assembly is configured to replace an existing side mirror assembly for mounting to known mirror scalps. The mirror glass is mounted to a rearward facing surface of a base plate of the mirror assembly by a piece of two-sided tape or heater panel. A printed circuit board is mounted to a forward facing surface of the base plate within a suitably shaped cavity. LEDs mounted to the circuit board are aligned with holes in the base plate. The circuit board is inserted into the cavity from an opposite side of the base plate from the mirror glass. A cover is sonically welded to the base plate to cover the cavity and hold the circuit board therein. The LEDs are illuminated in a sequential manner starting with an outermost pair of LEDs to an inner most LED.
