    摘要： A safety valve (4) incorporated in a tubing string (2) has a diameter considerably larger than that of the rest of the tubing string (2). A cable protector (10) is fastened onto the tubing string (2) at the lead in to the safety valve (4) to ensure that cables (8) extending along the outside of the tubing string are able to cope with the changes in diameter without strain or damage. The cable protector (10) is formed from two cast bodies (12) and (14) hingedly connected together to define a substantially circular inner cross-section. The upper body member (12) is provided with an elongate cable slot (26) in which the cable (8) is received. In addition, the upper body member (12) is shaped to give the cable protector an increasing internal cross-sectional size, or transverse dimension, along its length from one end (B) to the other end (B'), whereby the distance of the cable (8) from the longitudinal axis (X-X) of the tubing string (2) increases as it extends therealong. Thus the cable (8), received within the cable slot (26), is guided along a path which has a varying spacing from the longitudinal axis (X-X).

    摘要： A rolling cutter drill bit comprises a bit body (12) adapted for rotation about a longitudinal axis (8), a plurality of extending legs (14), and a cantilevered bearing spindle (16) formed on each leg (14), a plurality of rolling cone cutters (17, 18, 19) being rotatably mounted upon the bearing spindles (16) with the cone apices (15) adjacent to the longitudinal axis (8) of the bit, a plurality of cutting inserts (20) being secured in the rolling cone cutters (17, 18, 19), and being arranged in a plurality of rows (50, 52, 54), at least two of the rolling cone cutters (17, 18, 19) being intermeshing cutters, arranged such that they have intermeshing rows of cutting inserts (20), wherein at least one of the intermeshing cutters (17, 18, 19) has a groove (72, 74, 76, 78) arranged to register with one of the rows (54) of cutting inserts (20) of another of the intermeshing cutters (17, 18, 19), and wherein the groove (72, 74, 76, 78) contains a plurality of generally flat top bearing inserts (88).
