Abstract: The present invention provides multi-layer articles for use as a rail tie footings comprising, as the tie, an elongate rigid body having a substantially planar surface, and on the substantially planar surface comprising a a microcellular foam elastomeric pad, for example, of a substantially organic solvent free polyurethane, wherein the substantially planar surface has a peripheral landing on which there is no elastomeric pad and the elastomeric pad has a bulk density (ASTM D3676) of from 600 to 2000 Kg/m3 (0.6 to 2.0 g/cm3). In addition, the present invention provides molding methods wherein the microcellular foam elastomeric pad is molded directly on the rail tie to form a durable footing, wherein the rail tie forms the bottom boundary of a molding chamber during molding and molding comprises forming the top and side boundaries of the molding chamber by inflating an annular pneumatic seal, positioning the seal on the substantially planar surface of the elongate rigid body and keeping the microcellular foam forming materials under pressure during molding.

Abstract: A fluid dispensing device has a spool valve in a dispenser housing with a spool in a spool housing and a spool wall around the spool housing with entrance and an exit openings defined therethrough; an entrance channel in the dispenser housing proximate to the spool wall entrance opening; a force applying element in the entrance channel that applies force against the spool wall with entrance and exit ends with the exit end proximate to the spool wall; a hose adapter fitting with an entrance end extending out from and an exit end extending into the entrance and contacting the force applying element with a flow passage extending through it; and fluid communication through the hose adapter fitting flow passage through the force applying element and into an entrance opening in the spool wall; where the force applying element defines a tortuous path through which fluid must travel.

Abstract: A device for analyzing a physical characteristic of a film sample is described herein. The device includes a clamping system configured to hold the film sample. The device further includes a dart probe system configured to test a physical characteristic of the film sample. The dart probe system has a dart probe, a propulsion system configured to move the dart probe relative to the clamping system, and a force sensor configured to measure a force that the dart probe is subjected to during a movement of the dart probe. The force sensor is configured to measure a force imparted to the film sample when the dart probe comes in contact with the film sample.
