Abstract: Cable is installed into a duct, by increasing cross-sectional areas of subducting provided in the duct, so as to allow the cable to be received into the subducting, and then decreasing the cross-sectional area of the subducting containing the cable so as to reduce the volume occupied by the subducting in the duct. Cables may be inserted into the subducting, for example, by forcing compressed gas through the subducting, which simultaneously inflates the subducting.

Abstract: A fiber unit coating apparatus includes a chamber into which an uncured resin coated fiber unit is passed. Microspheres mixed with air are fed into the chamber via ducts and apertures. As a result rapid and even application of the microspheres can be achieved, and the system allows controllable application of the microspheres by varying the rate of flow of the air/microsphere mixture. Positive pressure chambers are provided to prevent the microspheres from blocking the inlet and outlet points where the fiber unit enters and leaves the chamber.
