  • Patent number: 10683954
    Abstract: An exemplary bulkhead connector assembly may include a housing that has an inner diameter surface, a first opening and a second opening. The assembly may further have a retainer attached to the housing and one or more feet extending radially inward from the inner diameter surface of the housing. The assembly can also include a collar that has a portion received within the first opening or the second opening. The collar may have an outer surface that cooperates with the feet of the retainer to hold a conduit within the housing.

  • Patent number: 10359140
    Abstract: An exemplary bulkhead (104A) connector assembly (100) includes a housing (106) having a first opening (138) and a second opening (130). The assembly (100) may further include a collar (108) that has a portion received within one of the first and second openings. The collar (108) may be rotatable to a latched position to hold a conduit (104B) within the housing (106). Further, the assembly (100) may have a detent (118) holding the collar (108) in the latched position when the detent (118) is moved to a locked position. The detent (118) in the locked position may have an indicator surface (112) providing tactile feedback indicative of the detent (118) holding the collar (108) in the latched position.

  • Patent number: 6899113
    Abstract: A pressure relief apparatus including a housing, a valve disposed in the housing, the valve having a first shoulder, a retainer disposed between the housing and the valve spool, the retainer having a second shoulder, a biasing member disposed between the first and second shoulders, and a metallic seal interface between the housing and the valve. The valve may be constructed with no dynamic elastomeric seals to reduce hysteresis.

  • Patent number: 6871882
    Abstract: An articulating ball-and-socket fluid coupling includes a ball body, a socket body, a primary retainer structure, an annular seal assembly and a secondary retainer structure. The primary retainer structure has a shaft extending through the ball and socket bodies to connect the ball body and the socket body together while permitting the ball body and the socket body to articulate relative to each other. The secondary retainer structure includes an annular member disposed in a ball receiving conduit portion of the socket member and connected to the socket body at or adjacent to an opening into the ball receiving conduit portion. The annular member has an inner secondary retainer diameter less than a spherical diameter of a partially spherical exterior surface defining a ball portion of the ball body so that the secondary retainer structure retains the ball body and the socket body connected if the primary retainer structure fails.

  • Patent number: 4097753
    Abstract: A comparator circuit for comparing two voltage levels in a C-2C A/D and D/A converter, comprising four cross-coupled active devices (FETs) in a latch arrangement whereby an offset voltage is used to compensate for imbalances in the comparator. The comparator includes a first FET having its gate electrode connected to the output of the D/A converter, and a second FET having its gate electrode connected to an analog input voltage. The first and second FETs each have one of their electrodes connected to a common voltage source. A third and a fourth FET have one of their electrodes connected respectively to the other electrode of the first and second FETs at first and second common nodes, respectively. The output of the comparator is provided at one of such first and second common nodes. The first and second nodes are also respectively connected to the gate electrodes of the fourth and third FETs in a cross-coupled arrangement.
