Abstract: A railway train includes a plurality of interconnected tank cars, each car comprising a tank provided with two lading conduits in the top thereof extending thereinto for communication with the interior thereof and each having an outer end extending above the tank, and toward the adjacent end thereof, the lading conduits of adjacent cars being interconnected by flexible connecting conduits. A crane is pivotally mounted on the top of one of the lading conduits on each car for maintaining the associated flexible connecting conduit at an elevation higher than that of the associated conduit coupling means to cause drainage of all the lading from the flexible conduit into the associated tanks.

Abstract: An unloading system for granular lading comprising a hopper having four cells each with a discharge opening in the lower portion thereof, a discharge tube below the hopper and communicating with each of the openings, two part-tubular sliders within the discharge tube in general longitudinal arrangement with each adjacent to two of the openings, each of the sliders being independently shiftable longitudinally within the discharge tube between a storage position and one of two discharge positions, and a handle for each of said sliders extending to one end of the hopper for controlling the slider from the one end of the hopper; there also is disclosed an end cap for the discharge tube securable thereto and holding the handles in the storage positions thereof, a slide rod being provided on the hopper to hold the end cap when it is disengaged from the discharge tube.

Abstract: The toilet system includes an evaporator tank having an inlet and an outlet that is at the top portion of the tank, a first electrical heater mounted on the tank, macerator/transfer pump means connected to the inlet of the tank to transfer flushed waste from a toilet to that tank, a vapor treatment system including a vessel having an inlet and a vent outlet and containing a bed of catalyst, first conduit means connected to the outlet of the tank and to the inlet of the vessel to transfer vapor from the tank to the vessel, a second electrical heater mounted on the conduit means to heat vapor passing from the tank to the vessel of the vapor treatment system, and second conduit means connected to the first conduit means between the mounting of the second heater and the evaporator tank to introduce pressure air into the vapor from the tank before the heating of the vapor.

Abstract: An intermodal tank container for use interchangeably in railroad, highway, marine and terminal modes, including a tank for containing lading and having means for loading lading thereinto and means for unloading lading therefrom, two spaced-apart end frames mounted respectively on the opposite ends of the tank, each end frame including a rigid framework surrounding an area greater than that of the adjacent end of the tank, and a tank support ring surrounding and rigidly secured to the adjacent end of the tank and rigidly secured to the framework for transmitting forces therebetween, the tank comprising the only connection between the end frames and having all parts thereof contained within an envelope defined by the peripheries of the end frames.

Abstract: A floating roof for floating upon and covering liquids stored in storage tanks, the roof including a deck generally conforming to the shape of the associated storage tank and having transverse dimensions and a thickness such that the deck is flexible, a pontoon around the outer periphery of the deck to impart buoyancy thereto, and a hermetically sealed hollow floatation ring mounted on the deck intermediate the center and the outer edge thereof, the weight of the floatation ring being asymmetrically disposed so as to place an area of the deck at a lower level than all other areas to provide a sump, and a drain communicating with the sump to drain liquid from the upper surface of the deck.
