Abstract: A solvent extraction process for the separation recovery of TNT and RDX from Composition B-containing munitions. The munitions also contain liner materials, such as asphalt and binders, and sealers, such as wax, each of which are also recovered by use of solvent technology.

Abstract: The present invention introduces a fiber suspension thickener, particularly adapted for thickening cellulose fiber. The thickener comprises a vat; a hollow filter assembly in the form of a horizontal cylindrical drum disposed within the vat, whereby the drum may be rotated by a motor around its horizontal axis, and whereby the cirumferential walls of the drum are made of a filter material; either a spray nozzle or some other supply conduit that furnishes a fiber suspension into the interior of the vat, so that the drum becomes submerged within a pool of the fiber suspension; a discharge outlet for discharging the fiber suspension on the ascending side of the rotating drum; and a turbulence creating device, that can take many forms, for creating turbulence and mixing the fiber suspension on the ascending side of the rotating drum.

Abstract: A railway car adapted to convey cylindrical objects such as coils includes a plurality of fixed trough members and sections of shiftable inclined trough assemblies disposed atop a support deck. By selectively laterally displacing the shiftable trough assemblies the car is alternately configured to provide single/triple or double troughs, or a combination thereof, in order to achieve maximum lading capacity in any one car regardless of the diameters of the coils. Positioning elements on each shiftable trough assembly alternately mate with a fixed trough member or separate positioning elements on the support deck to specifically define the various trough modes. A lock assembly is operable to engage a retainer element carried by each shiftable trough assembly when located in either mode.

Abstract: A railway hopper car includes a curved roof having a roof sheet provided with lateral edges each joined to the top of a car side sheet by a top chord assembly. Each top chord assembly includes a top chord fully disposed within the car interior and having a vertical leg joined to the interior surface of a side sheet while an opposite inclined or angular leg is joined to the interior surface of the roof sheet. A curved cover overlies both top chord legs and forms, with the roof sheet and side sheet, a smooth continuously descending profile from the top centerline of the car roof to each of the car sides.
