摘要： In a method and apparatus for detecting leaks in riser and lid assemblies, a difference in pressure between the inside of the riser and cover assembly and the outside is created and monitored to insure that no leaks exist. Preferably, a vacuum is created on the inside of the riser and cover assembly. This vacuum is then monitored for a set period of time to insure that the total change in pressure does not exceed a threshold. In a highly preferred embodiment, an apparatus automatically creates the desired vacuum and then isolates a vacuum gauge to monitor the vacuum in the riser. Method for isolating a leak are also presented in the event that a leak is detected.

摘要： A retaining system in which straps are provided with hooks that remain engaged with retaining loops even when tension on the straps is released and in which the tightening mechanism includes rods which are located partially below a rib surface on which the straps are placed such that the ends of the rods are near the plane of the strap ends, thereby greatly reducing the bending moment applied to the strap ends and threaded rods. The hook preferably includes a cavity opposite the hook end that will engage the retaining loop when no tension is on the line. In some embodiments, the hook includes a spring-loaded retaining clip to further ensure that the hook does not become disengaged from the retaining loop. The tightening mechanism includes two rods, each of which is positioned to one side of a rib on which the straps rest.

摘要： A reversible latching hinge for the roof of a container such as a railway car which is adapted to be inverted to a discharging position. The latching hinge allows the roof to pivot away automatically from the opening of the container during inversion. The reversible latching hinge is designed so as to minimize or eliminate undesirable impact loading that may arise from lateral displacement of the roof during inversion. The construction includes flanges extending laterally outward from the roof and terminating in ears which extend toward latch bars mounted to the container. Contact between the ears and the latch bars forms a pivot point for the roof. The construction also includes freely pivoting hooks which, on the upper side of the roof engage the latch bars to prevent the roof from falling off of the container. The hooks on the lower side disengage from the latch bars by gravity to permit the roof to swing outwardly during inversion.
