Abstract: A steering mechanism for a rail vehicle includes two steering arms, each including a pair of support arms that have a joining component with a recess. The two steering arms are articulated in a manner that maintains a minimum separation between the steering arms so that the arms can rotate relative to one another. The minimum separation is maintained by an insert that installs into the joining component recesses components of each of the steering arms. The insert has two sides, each side having a flexible material and forming a shape that mates with the recess. The insert provides resistance to the rotation between the first and second steering arms, and the resistance depends on the stiffness of the flexible material of the insert.

Abstract: A fluid flow detecting system and approach incorporating a collar configured to be clamped to a fluid conveyance mechanism, a temperature probe held within temperature sensing range of the fluid conveyance mechanism with the collar, an ambient temperature sensor, and a controller connected to the temperature probe and the ambient temperature sensor. The controller may incorporate a data analytics module to determine fluid flow starts, characteristics of fluid flows and fluid stops from temperatures received from the temperature probe and the ambient temperature sensor. The system may further incorporate a heater in contact with the fluid conveyance mechanism to increase speed and accuracy of determinations of fluid flow starts, characteristics of fluid flows and fluid stops by the data analytics module.
