The sideframe and bolster of a railway car truck are constructed such that basic overall sideframe and bolster appearance is maintained, but the actual material it is constructed of is changed. The material used is changed from cast steel to an austempered metal, such as, cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (&#x2003;)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (&#x2003;)}3. This immediately allows for a reduction in weight. A second benefit is that iron is easier to pour than steel and actually increases in volume, slightly, as metal cools compared to steel which shrinks. Efficient use of materials is improved, meaning less metal is used to make the same final shape, as a way of reducing the sideframe and bolster weight. Both factures combined allow for a lighter weight railway car truck, sideframe and bolster, while utilizing standard designs.

The coupler system of a railway car truck is constructed such that basic overall appearance may be maintained, but the actual material of which it is constructed is changed. According to one embodiment, the coupler is constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (&#x2003;)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (&#x2003;)}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal coupler and components thereof. A second benefit of embodiments of the present invention provides for a more efficient use of materials, meaning less metal is used to make the same final shape, as a way of reducing the coupler weight. Both factures combined allow for a lighter weight coupler, while utilizing the standard designs. Alternate coupler configurations are disclosed for further reducing coupler weight.

Lightweight yokes are provided. According to some embodiments, the basic overall appearance of the yoke may be maintained, but the actual material of which it is constructed is changed. According to other embodiments, the yoke is provided with an improved lightweight construction, and, yet other embodiments the yoke may be provided with an improved construction and formed from a preferred material. Yokes may be constructed from cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in{circumflex over (&#x2003;)}3, which is approximately 8% less than steel, 0.283 lbs/in{circumflex over (&#x2003;)}3, thereby allowing for a reduction in weight over steel. A suitable austempering process is used to produce the austempered metal yoke. Yokes have improved configurations which may require less metal to produce the yoke. Both, the lightweight material and improvements in configuration of the yoke structure may combine to provide a lighter weight yoke.

The invention is a herbicidal composition containing an alkanolamine salt of an dicamba capable of remaining as a single phase liquid over a period of at least 1 week and containing low amounts of water and high loadings of the salt. Such herbicidal compositions are capable of remaining liquid in the absence of high amounts of water, thereby enhancing their capacity to remain liquid over an extended period of time when exposed to environmental conditions to improve their effectiveness to transport the active salt through a leafy substrate and can reduce transportation costs by increasing the salt loading without compromising the stability of the composition.

A process for forming a cross-linked thermoplastic elastomer is disclosed herein. The cross-linked thermoplastic elastomer is a thermoplastic cross-linked copolyester and is preferably formed by heating a first mixture containing a thermoplastic elastomeric base material, a monomeric diisocyanate comprising between 1 to 10% of the total weight of the first mixture, and a second mixture of a first diamine and a second diamine comprising between 1 to 10% of the total weight of a total reaction product. The heated first mixture, which is flowable, is injected into at least one injection molding device, with the second mixture injected at predetermined intervals to create a homogeneous reaction product. The reaction product may be injected into a mold to produce articles.

The sideframe and bolster of a railway car truck are constructed such that basic overall sideframe and bolster appearance is maintained, but the actual material it is constructed of is changed. The material used is changed from cast steel to an austempered metal, such as, cast austempered ductile iron; whereas cast iron has a density, 0.26 lbs/in^3, which is approximately 8% less than steel, 0.283 lbs/in^3. This immediately allows for a reduction in weight. A second benefit is that iron is easier to pour than steel and actually increases in volume, slightly, as metal cools compared to steel which shrinks. Efficient use of materials is improved, meaning less metal is used to make the same final shape, as a way of reducing the sideframe and bolster weight. Both factures combined allow for a lighter weight railway car truck, sideframe and bolster, while utilizing standard designs.

A wear plate for use with a railway truck, the wear plate being configured for installation on a downwardly facing surface of a pedestal opening of a side frame of a railway truck. The wear plate includes a base and a pair of side walls extending upwardly from opposite sides of the base with inwardly disposed locking features designed to engage the pedestal when the wear plate is installed, the locking features in a preferred embodiment being configured as resilient projections that engage, clamp or drag lock onto opposite sides of the pedestal with the base of the wear plate protecting the downwardly facing pedestal surface. The wear plate may be constructed from malleable or ductile metals or plastics.

A polymer spring has a hollow tubular polymer body, wherein the first end portion of the body, the second end portion of the body, and the mid-portion of the body together substantially maintain an annular cylindrical column structure throughout the length of the body from the first end portion of the body to the second end portion of the body, such that the mid-portion of the body has a substantial portion that is in direct alignment with the first end portion of the body and the second end portion of the body when the spring is compressed to eliminate or reduce the chances of the spring failing caused by the spring folding or buckling and to reduce material fatigue in the polymer spring associated with folding or buckling.
