Abstract: An apparatus and method for preventing drill string drag. Rotation encoders are provided for tracking the rotation of an inner and outer member of a dual-member drill string. Based upon the drilling conditions, the readings of the encoder can detect when the inner member is dragging on the outer member. When such a drag condition is detected, a processor can trigger remedial measures, which may include increasing a rotation rate of the inner member, sending a warning signal, stopping operation, or a combination of these.

Abstract: An improved carpet stripping device (10) designed for rapid, easy removal of adhesively secured carpeting is provided which includes an elongated cable or line (12) connected at one end thereof to a powered winch assembly (14). The opposite end of the line (12) is connected with an improved carpet connection assembly (16) allowing ready and secure connection to a pulled margin (60) of the carpeting to be stripped. The assembly (16) includes a stretch of flexible cable (50), together with a pair of spaced apart, carpet margin-gripping jaw members (42, 44) positioned on the cable (50) and shiftable along the length thereof. In use, the assembly (16) is initially positioned on a pulled and slitted margin (60) of carpeting, and is rolled to form an interlocking convolution (66), with the cable (50) extending through the carpet slit (62). The attached assembly (16) is then coupled with the line (12) for carpeting stripping operations.
