A safety latch for a mud skip container includes a first latch that is pivotal within a bracket that is mounted to a top of the container. The first latch may include a pivoting head with a downwardly projecting catch and an arm connected to the head. The arm extends through an aperture in the bracket and a spring is disposed about the arm between the head and an end wall of the bracket. The safety latch further includes a second latch mounted to a pivoting lid of the container; and, the second latch includes an upwardly projecting catch on a head of the latch. The head of the second latch is positioned over a pivot axis of the lid and positioned relative to the first latch such that the catches of respective first and second latches engage one another when the lid is opened.

A cap assembly (40) for attachment to an external fixture (44) on a tank (52) of a tanker trailer (50), including: a collar (42) configured to secure the cap assembly to the tank external fixture and defining a collar opening (46) concentrically aligned with an opening (54) of the fixture; a lid (60) that is moveable between a closed position where the lid covers the collar opening and is in sealing engagement with the collar, and an open position where the lid is vertically raised from the collar and pivoted laterally away from the collar opening; and an actuator assembly (72) that is configured to move the lid from the closed position to the open position during a single stroke of the actuator assembly, and which is remotely operable from a location off of the tanker trailer.
A spring capture assembly is provided for securing a compression spring of a spring-biased mechanism, such as a spring-biased pressure relief valve, to permit disassembly of the mechanism without risk of damage or injury associate with rapid resiling of the spring from a compressed state. The assembly includes a tool, a housing having an opening for admitting passage of the tool and capturing the spring at one end, a spring retainer, and a compression spring mounted within the housing and captured at one end by said housing and toward an opposite end by the spring retainer. The tool is adapted for mating with the spring retainer and the housing to compress the spring therebetween. The spring capture assembly may be incorporated into a pressure relief valve for venting pressure and/or vacuum from a pressure vessel. Provided also is a method for disassembling a spring-biased mechanism including a spring capture assembly.

In one embodiment, the valve (100) comprises: (a) a housing (101) configured to interengage with a container (401), and having at least one axis (101a) and at least one aperture (105); (b) a first poppet (110) axially movably within said housing (101) between a first closed position and a first open position; (c) a second poppet (120) axially movable within said first poppet (110) between a second closed position and a second open position; (d) a first seal (111) between said first poppet (110) and said housing (101); (e) a second seal (121) between said first poppet (110) and said second poppet (120); (f) a first resilient member (112) disposed within a first space (130) between said housing(101) and said first poppet (110), and having a resilient force sufficient to hold said first poppet (110) in said first closed position such that said first poppet (110) urges said first seal (111) against said housing (101) when a pressure differential axially across said first poppet (110) is below a first point, and to allow said first poppet (110) to move in said first direction to said first open position when said fluid pressure differential exceeds said first point; and (g) a second resilient member (122) disposed within a second space (140) between said first poppet (110) and said second poppet (120), and having a resilient force sufficient to hold said second poppet (120) in said closed position such that that said second poppet (120) urges said second seal (121) against said first poppet (110) when a pressure differential axially across said second poppet (120) is below a second point, and to allow said second poppet (120) to move in a second direction, different from said first direction, to said second open position when said pressure differential exceeds said second point.
A valve includes a housing configured to interengage with a container, a first and second poppets axially movable between open and closed positions, a first seal between the first poppet and the housing, a second seal between the first poppet and the second poppet, and first and second resilient members disposed within the housing and urging the first and second poppets toward the closed position.
