contact slide base line apparatus
A modified contact base line apparatus consisting of two steel measuring bars (rods), each 4 meters in length, so mounted that contact was effected by making lines on a rod and a contact slide coincide. Each rod formed a metallic thermometer with two zinc tubes, one on each side of the bar; opposite ends of the bar were fastened to one end of each tube while the other end was free to move as temperature changed.
