  • Patent number: 4239424
    Abstract: A method and device for evenly distributing granular material such as plastic pellets into a railway hopper car to reduce the valley angle, eliminate void spaces, and increase the volume of material in each hopper. A cone-shaped deflector is placed in line with each hatch opening at a point below the roof line. The deflector directs material horizontally away from the hatch opening to reduce and virtually eliminate the valley angle for most granular materials. The cone is hung from support struts which may be suspended from an angular mounting ring which is mounted atop the hatch coaming.

  • Patent number: 4235830
    Abstract: Means and method of operating a tunnel kiln in which green carbon articles are baked in the ware (article) space of a baking zone by heat produced by the combustion of fuel directed to chambers adjacent the zone. The combustion chambers are connected in fluid communication with flues extending lengthwise of the kiln, the flues having a pressure gradient that extends lengthwise of the flues. The method of the invention includes the step of changing the pressure gradient within the flues such that a pressure differential between the combustion chambers and the ware space is effected that causes products of combustion to flow into the ware space from the combustion chambers in amounts sufficient to impede and prevent the deposition of coke formations on the walls of the space without burning the carbon articles.

  • Patent number: 4234221
    Abstract: A device for securing a hatch cover has a locking strap pivotally attached at one end and adapted to overlap adjacent end portions of trough hatch covers. The locking strap has a free end engaged by a locking bar which pivots at right angles thereto. The locking bar is part of a unit or module which includes a shackle and a latch hook for holding the locking strap. The shackle is pivotally attached to the locking bar and is weighted with ballast to always be disposed in a vertical position for locking. The latch hook is also weighted and allowed a small amount of rotation to compensate for wear of the sealing gaskets to insure continuous locking engagement between the shackle and the latch.

  • Patent number: 4233795
    Abstract: A replacement roof panel for repairing damaged railway car roofs in the field. The damaged portion is cut away leaving an opening in the roof. The repair panel is fabricated to the desired width and has reinforcing end portions that form laterally extending stiffening members. The end portions are shaped to provide slots along the lateral edges of the repair panel for receiving the edges of the existing roof sheet. The repair sheet is then welded along its edges to the existing roof sheet and to the side plates of the car.

  • Patent number: 4226203
    Abstract: A pallet having a precast, prestressed concrete grillage superstructure including layers of elongate elements, each successively higher layer being transverse to the layer below it for heavy load bearing objects such as an industrial processing plant. The long elements are not only useful in providing the load-bearing points, but are useful in providing long channels between the elements which are useful as manways and for carrying pipe, conduits and the like that are associated with an industrial processing plant, the heavy load typically lifted and carried by such a pallet. The intersection points or junctions of the elements from layer to layer are load bearing points for distributing in radiating fashion the load placed on the top deck slab of the pallet. The pallet is suitable for transport by a submersible seaworthy vessel located beneath the pallet.
