摘要： A cellular thermoplastic product such as a railway crosstie is produced by an apparatus comprising extrusion means for producing a web of a foamable thermoplastic polymer such as polyethylene, a mold corresponding to the size and shape of the cellular product positioned adjacent the extrusion means to receive the web of foamable thermoplastic polymer, and means for imparting relative reciprocal motion between the mold and the extrusion means in a direction generally normal to one of the surfaces of the web such that the web is deposited in layers within the mold. In producing a cellular thermoplastic product by the method of the invention, the steps include plastifying a thermoplastic polymer such as polyethylene in the presence of an expanding agent to produce a foamable thermoplastic polymer, forming the foamable thermoplastic polymer into a web, depositing the web into a mold, and imparting relative reciprocal motion between the web and the mold in a direction normal to at least one surface of the web such that the web is deposited in layers within the mold. The foamable thermoplastic layers in the mold fuse together at their mating surfaces thereby resulting in the cellular thermoplastic product.

摘要： A method for restoring and reusing railroad ties and the resulting product are disclosed. According to the method, otherwise spent wooden ties are sorted as to their apparent suitability for providing a core for reuse. Those found unsuitable are discarded, while those found to be suitable are milled or trimmed about their dimensions to define a suitable core. That core is banded about a transverse perimeter and then submitted to a reaction injection molding process by which urethane or other suitable polymers impregnate the various voids, holes and cracks in the core, bond with the bands, and define a finish unit having the overall size and configuration of previously known railroad ties. The encapsulated product is then capped or plugged at the ends to ensure that the resulting product is impervious to penetration by the environment.

摘要： A laminated and encapsulated railroad tie structure and its associated method of manufacture. A wood core of laminated wood slats is inserted into an extruded sleeve of scrap tire rubber and polyurethane. A urethane adhesive laminates the wood slats together and serves as a lubricant and bonding agent for placement and secured engagement of the sleeve about the core. End caps are securedly engaged at each end of the composite, being secured to both the wood core and sleeve. The bottom and side surfaces of the sleeve are characterized by longitudinal grooves or slots for engagement with a railroad bed.

The main body portion of the tie is wood, having a rectangular cross section and a flat upper and lower surface. A plurality of flat plastic plies made of shredded wood fibers or wood chips bonded together by a thermal setting resin are, in turn, bonded to the upper and lower surfaces of the main body portion.

摘要： A reinforced railroad crosstie formed by molding and bonding comminuted lignocellulosic material into a monolithic beam around a plurality of reinforcing rods, each of which has a plurality of spaced protrusions fixedly attached along its length at specific positions relative to the midpoint of the tie and the rails mounted thereon. The reinforcing rods are positioned within the crosstie proximate lines of maximum tensile stresses expected to be induced into the tie by different bending influences caused by passing trains and varying conditions of the underlying ballast. The protrusions are configured and spaced in pairs on either side of respective points of maximum expected stress to ensure maximum transfer of each stress from the lignocellulosic material to the rods. The rods are also positioned within the crosstie so as to avoid contact with the spikes employed to fasten the rail to the tie.

摘要： A system for crafting railroad crossties of compressed bamboo is described. The system employs a hydraulic press configured to effectively compress multiple stalks of bamboo into a strong unified beam within a mold. Bamboo is first mashed, dried, and treated. A resin is employed as a permanent adhesive, binding the stalks together. The bamboo is stacked within a mold and compressed under the pressure exerted by the hydraulic press. An oven is used to heat the compressed bamboo, and then the bamboo is cooled. The compressed bamboo beam may then be trimmed to remove excess bamboo, and is cut into crosstie segments if needed. The resulting crosstie is sturdy, ecologically friendly, and rapidly manufactured.
