In a design as shown in Fig. 14s—(B1-5). the expansion and con-traction would be taken up by a side movement of the different sec-tions. Fig. 14(5—(Bi-6) shows a diagram in which the position ofthe parts when cold is indicated by solid lines and when heated, bydotted lines. The difference in position of the parts when cold andhot as indicated by, a, may be ass
