Abstract: A medullary nail (10) has a cavity (12) in which an inner part (20) can slide longitudinally without being able to rotate. The wall (11) of the medullary nail (10) which forms the cavity (12) is traversed on opposite sides by an elongated hole (16) in the region of the driving-in end (14). At least one fastening hole (22) aligned flush with the elongated hole (16) is provided in the inner part (20). When the connecting screws are driven into the spaced fastening holes (15, 16, 22) and an osteotomy is located between the connecting screws (15, 22), the edges of the osteotomy are moved apart as the inner part slides longitudinally, and the slowly widening gap between the edges of the osteotomy becomes filled with bone tissue.

Abstract: Strip elongation in a continuous annealing furnace is controlled by passing the strip around a first driven roll, thence through a portion of the furnace, thence around a second driven roll, wherein the elongation of the strip is sensed. One method is to sense the amount by which the peripheral speed of the second roll exceeds the peripheral speed of the first roll. Roll speeds are monitored by precision resolvers. Another method is to utilize a strip width measurement to determine elongation. Mechanisms are used for profiling tension throughout the furnace length.
