Push-cables and associated apparatus for pipe inspection systems are disclosed. In one embodiment a pipe inspection system includes a camera head, a push-cable including an outer covering enclosing a plurality of electrical conductors for transmitting signals and/or power between the camera head and an electronic device operatively coupled to the push-cable, and a spring assembly disposed about the push-cable near the distal end where the spring assembly comprises a spring with a tapered flex section having a varying cross-sectional area and/or a varying cross-sectional shape.

Push-cables and associated apparatus and systems are disclosed. In one embodiment, a push-cable assembly for use with a pipe inspection system may include a push-cable element having a proximal end and a distal end, with a spring assembly having varying flexibility coupled to or near the distal end. The spring assembly may include an outer coiled spring having a proximal and a distal end, and an inner coiled spring nested at least partially within the outer coiled spring. A camera head and/or other elements such as a cutting or jetting apparatus may be coupled at or near the distal end.

The invention relates to clutch disc comprising a torsional vibration damper which has an inlet part and an outlet part and a spring device operatively arranged in the peripheral direction between the input part and the output part, wherein the spring device is formed from the first and second spring elements connected behind one another and separated by an intermediate flange, and a centrifugal pendulum which has a pendulum mass carrier arranged about an axis of rotation of the clutch disc and pendulum masses accommodated on same on pendulum paths for oscillation and arranged in a distributed manner over the periphery. In order to improve the insulation effect of the torsional vibration damper and the centrifugal pendulum and/or better adjust same to the required application, the pendulum mass carrier is coupled for conjoint rotation with the intermediate flange and centrally accommodated on the output part.

A lock-up device includes a drive plate, a driven plate, first torsion springs, second torsion springs, a spring holder and a rotation restricting unit. The rotation restricting unit is configured to restrict and bring the first torsion spring in each group and the second torsion spring in each group to a deactivated state by at least either of engagement of the spring holder with the driven plate or engagement of the drive plate with the spring holder.
