Abstract: A modular system for an automotive vehicle configured to permit removal of a removable structural module from and reattachment to an automotive vehicle is described. The system includes a removable structural module comprising a body, a support structure configured to receive and support the removable structural module and to permit the removable structural module to be releasably attached to an automotive vehicle, a sensing arrangement configured to permit confirmation of secure attachment of the removable structural module to the automotive vehicle and configured to permit identification of a predetermined type of the removable structural module, and a computer configured to identify the predetermined type of the removable structural module from among multiple possible predetermined types of removable structural modules. The removable structural module comprises multiple connecting structures that permit the removable structural module to be releasably secured to the automotive vehicle.

Abstract: A method of manufacturing cement clinker includes a rotary cement kiln having a feed end, a mid-kiln feed location, and a burning end. The rotary kiln is tilted downwardly from the feed end to the burning end so that material introduced into the feed end travels downwardly to the burning end. Heat is directed at the burning end of the rotary kiln. Raw feed material is introduced in the feed end of the rotary kiln. Calcined material having a particle diameter of up to 12 inches is introduced at the mid-kiln feed location. The mid-kiln feed location is arranged in a calcining zone of the rotary kiln.

Abstract: A compressible pressure compensating member is disposed within a sealed lubricant volume enclosing a bearing and seal system of an earth boring apparatus. Lubricant is maintained within the volume by metal face seals so that both the bearing and the seal structure are lubricated thereby. As the lubricant expands, due to thermal expansion under use, the increased pressure is accommodated by compression of the compressible member so that no lubricant is expelled through the seals. When the lubricant cools and contracts, the compensator expands to maintain the lubricant volume at the initially filled level.
