Abstract: An apparatus and method for automatically inserting a cable into a protective jacket. A longitudinal cut is made in the protective jacket and the cable is inserted into the longitudinal cut. The cable and jacket are transported through the apparatus along an arcuate guide path formed by a friction wheel.
Abstract: A device for regulating the flow of gas from an environment. The device includes a shell forming a path through which fluid flows. A fixed grate is disposed in the path so that as fluid flows in the path the fixed grate does not move. A movable grate assembly includes one or more plates and a movable grate attached to the one or more plates. The one or more plates includes an integral hinge such that the plate can rotate about the integral hinge. When the movable grate moves with respect to the fixed grate the impedance on the flow varies.
