Abstract: An arrangement for driving the oil and water pumps of an internal combustion engine in which the pumps are driven independently of the engine's speed. In one arrangement the oil pump is activated prior to starting the engine to provide adequate lubrication to the engine during the starting operation. The activation of the water pump may be controlled by the temperature of the engine such that it is not needlessly driven when the engine is cold.

Abstract: The present machine tool comprises a grinding wheel rotatably mounted on a machine bed. A feed advance is movably mounted on the bed, and carries a vertical frame. Head and tail stocks are mounted in the vertical arms of the frame, for supporting a work piece to be moved with the feed advance table into engagement with the grinding wheel. The frame is angularly displaceable on the feed advance table about a vertical axis, to enable variation of the direction of feed with respect to the axis of a work piece mounted between the head and tail stocks.
