Abstract: A gyratory crusher including a main shaft installed into a main frame. The gyratory crusher includes a seal ring assembly having a seal ring that engages a portion of the main frame to limit the movement of dust and particles during crushing operations. The seal ring assembly includes a plurality of seal ring retention assemblies that are each movable between an engaged centering position and a retracted operating position. In the centering position, each of the seal ring retention assemblies holds the seal ring in a centered position. When the seal ring is urged outward, the seal ring retention assemblies move away from the centering position to the retracted position. Each of the seal ring retention assemblies can be moved to the centering position from the exterior of the seal ring assembly to center the seal ring before installation of the main shaft into the frame of the crusher.

Abstract: Simulation of vehicle telematics events is provided by a vehicle telematics simulator. The simulator performs a simulation of vehicle telematics events based on user-defined parameters to generate simulation data. The simulation data is formatted according to a reporting protocol to obtain formatted simulation data. The reporting protocol may be the same reporting protocol used by vehicle-based telematics devices to format and report measurement data for real-world vehicle telematics events. The formatted simulation data is provided to a vehicle telematics service hosted at a server system for processing. The formatted simulation data is processed along with formatted measurement data representing measurements of real-world telematics events via a common processing pipeline of the vehicle telematics service. The vehicle telematics simulator may reside at a client computing device or at the server system that hosts the vehicle telematics service.
