A cement mixture is provided for preventing or reducing the formation of micro-cracks during hydration. The use of a servo-loop creates an energy potential in an energy storage element and maintains that required energy potential using the functionality of the communications controller that concurrently draws required power from the energy storage element. The sensor generates a sensing signal with respect to processing parameter of the machine tool. In one embodiment, communication device includes a receiver section for receiving an acknowledgment or a non-acknowledgment signal in response to information transmitted by the transmitter section of the communication device. The device includes a plurality of hooking protrusions that are in angled relation with each other and contain compound bends to permit engagement with the support structure of the object to be lifted.
