  • Patent number: 10919432
    Abstract: A tank and a method of carrying a load and discharging a load therefrom. The tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.

  • Patent number: 8833268
    Abstract: Railroad tank cars are provided that include an inner tank, an outer tank, and tank to tank clearance between the inner tank and the outer tank. Insulation and spacers can be located within the tank to tank clearance. The inner tank can shift within the outer tank, and spacers can crush, under significant force loading, such as impact forces generated during a collision or derailment. The inner tank, insulation, spacers, and outer tank thus form an energy absorbing system that reduces the likelihood that the inner tank will be breached, and that a hazardous material contained therein will be released, under such conditions.

  • Patent number: 6447157
    Abstract: Disclosed is an agitator assembly which comprises an agitator and means for mounting the agitator assembly on top of a tank. The agitator comprises a shaft, a propeller fixed to one end of the shaft, and means for rotating the shaft to provide an axial discharge from the propeller of at least 4.0 m/sec with a flow equivalent of at least 0.2 tank volumes/minute. The agitator is mounted on top of the tank so that the shaft enters the tank at an angle a to the longitudinal axis of the tank of between about 30 and about 60 degrees and at an angle &bgr; to the transverse vertical axis of the tank of less than about 50 degrees. Also disclosed is a method of shipping solids that are soluble in a solvent. The solids are placed in a tank on which the agitator assembly has been mounted. The quantity of solids placed in the tank exceeds the amount that will dissolve when the tank is filled with the solvent. The tank is transported to the location where the solids are to be removed from the tank.

  • Patent number: 6357363
    Abstract: A railway tank car of light weight and high cargo load capacity in which a tank shell structure is carried on and unified with an underframe including a stub sill at each end, a pair of spaced apart saddle bolsters, each joined to a respective one of the stub sills, and a center sill interconnecting the saddle bolsters. The tank shell rests on and is welded to the center sill, the saddle bolsters, and the stub sills, so that the tank shell is an integral part of the car, and both static and dynamic load forces resulting from train operation and from cargo loads are shared by the tank and the underframe. The underframe is constructed primarily of welded flat plate, with a minimum of specially formed parts and difficult welds, in order to simplify and minimize the costs of construction.

  • Patent number: 6328064
    Abstract: A drain pipe support advantageously acts as a guide for insertion of a drain pipe and secures the drain pipe in a desired position for draining of a fluid filled tank. Additionally the drain pipe support also advantageously guides fluid into the drain pipe so that efficient draining may be accomplished. The drain pipe support is comprised of an interior hollow portion which includes a tapered central portion 34 at a lower end thereof in order to guide the drain pipe and form a seal between the drain pipe and the drain pipe support. The drain pipe support advantageously has a hollow body which includes a support member that extends from the upper sides of an outer wall of the body. The support member is desirably formed in a substantially uniform circumference around the body of the drain pipe support.

  • Patent number: 6286438
    Abstract: A baffle plate assembly for reducing the amount of corrosive liquid contained within a railroad car from contacting a pressure relief valve connected to the railroad car. The baffle plate assembly includes a baffle body having one end connected to an upper plate and the other end connected to a lower plate. The baffle body includes a plurality of slotted openings and radially extending downwardly sloped drainage openings. The lower plate includes a radially extending downwardly sloped drainage surface that further includes a plurality of channels for draining liquid out of the baffle body. The baffle plate assembly is connected to the railroad car adjacent to the pressure relief valve such that air and/or other gases pass through the baffle plate assembly and then the pressure relief valve. Air and/or other gases pass from within the railroad car through the plurality of slotted openings defined in the baffle body into an interior chamber of the baffle body.

  • Patent number: 5785078
    Abstract: A safety vent for a railroad tank car has a housing mounted about an opening on the top of the car. The housing body defines a cavity which contains a surge protector and a rupture disk. The rupture disk is designed to open at a known pressure and allow controlled venting of the pressure in the car. A securement cap threaded into the cavity centers the rupture disk in a seat formed in the surge protector. Removal of the securement cap provides quick, easy access to the rupture disk and surge protector for inspection and replacement without removing the housing body.

  • Patent number: 5303843
    Abstract: A fluid transport apparatus including an elongated fluid vessel for transporting fluid, such as LPG. One or more breakable containers of compressible fluid are positioned within the fluid vessel. The containers are adapted to break by the force of the vessel fluid surging against them when the fluid vessel is impacted. The compressible fluid within the containers dissipates or eliminates the water hammer pressure resulting from the impact and thereby prevents the walls of the fluid vessel from failing. The breakable containers can be end partitions with one or more rupture discs thereon or collapsible pressurized containers, such as ordinary tennis balls, held at one or both vessel ends by internal breakaway partition walls.
