1. A system comprising:
a displacement-agent source containing a displacement agent; a friction-pin unit operatively coupled, via a conduit, to the displacement-agent source to allow transmission of the displacement agent from the displacement-agent source to the friction-pin unit, the friction-pin unit comprising:
a sleeve;a guide cone formed at a first end of the sleeve;a shaft disposed coaxially within the sleeve; anda plurality of friction pins extending radially outward from the shaft. |
