Abstract: A backing ring assembly is for railway axles and includes a backing ring and an annular insert having L-shaped axial cross sections. The insert includes a sleeve portion fitted to a radially outer cylindrical surface of the backing ring, which delimits a first axial section thereof. The annular insert sleeve portion includes first and second axial sections hingedly connected by an intermediate, reduced thickness section designed to form a plastic hinge. The first axial section of the sleeve portion projects axially from the first section of the backing ring, which is provided with an annular projection designed to induce elastic deformation of the reduced thickness section to ensure that the second axial section of the sleeve portion is always coupled with the cylindrical outer surface of the backing ring first axial section by an interference fit.

Abstract: Devices, systems, and methods of the present disclosure are directed to accurate and non-invasive assessments of anatomic vessels (e.g., the internal jugular vein (IJV)) of vertebrates. For example, a piezoelectric crystal may generate a signal and receive a pulse echo of the signal along an axis extending through the piezoelectric crystal and an anatomic vessel. A force sensor disposed relative to the piezoelectric crystal may measure a force exerted (e.g., along skin of the vertebrate) on the anatomic vessel along the axis. The pulse echo received by the piezoelectric crystal and the force measured by the force sensor may, in combination, non-invasively and accurately determine a force response of the anatomic vessel. In turn, the force response may be probative of any one or more of a variety of different characteristics of the anatomic vessel including, for example, location of the anatomic vessel and pressure of the anatomic vessel.

Abstract: A tonable, radiation sensitive composition, whose adhesion properties can be controlled by the presence of a polydiorganosiloxane with polar and/or ethylenic unsaturated groups and a process for preparing multicolored images using such a composition is described.
