Abstract: An assembly comprises a vessel comprising a shell exhibiting at least one opening extending therethrough, a structure covering an internal surface of the shell, and at least one plug device contacting the shell and the structure. The at least one plug device comprises a rigid body comprising a male connection structure longitudinally extending into the least one opening, and a base structure extending outwardly beyond a lateral periphery of the male connection structure and positioned longitudinally between the structure and the shell. A plug device for a milling application, and a method of plugging a component of an assembly are also described.

Abstract: A wear indication device comprises an outer body and a sensor configured to detect and indicate wear to the outer body. The outer body exhibits an opening extending at least partially therethrough and comprises a stem region, and a head region integral with the stem region and extending outwardly beyond a lateral periphery of the stem region. The sensor is positioned within the opening and comprises an output device. An assembly, and a method of detecting wear to a component of an assembly are also described.

Abstract: A wear indication device comprises an outer body exhibiting at least one opening extending at least partially therethrough, and at least one sensor within the at least one opening. The at least one sensor comprises at least one probe, and at least one electronic device operatively associated with the at least one probe. The at least one electronic device comprises at least one power supply and at least one output device. An assembly, and a method of detecting wear to a component of an assembly are also described.
