A method of crushed ground-wood processing comprises charging the input between two relatively revolving and displaced conical surfaces with simultaneous dimension separation variation by circulating vibrations causing the surfaces to apply variable squeezing pressure and lateral or normal forces to effectively compress and rub the bark from the wood surface.

A threadless connector for cable pipes or electrical conduit that includes two half-couplings having tightening flanges along their lateral edges or faces. Female and male necks and beads extend along the cooperating lateral faces to form longitudinal seals when the half-couplings are clamped together. Internal radial grooves located near the outer parts of both ends of the half-couplings cooperate with split compression rings the outer surface of which compresses against the conic grooves and the inner edges bite into the connected pipe sections to form radial seals therewith. The half-couplings can be either two separate congruent parts or joined along one edge as desired.
