Abstract: A heat source is formed within one piece of a multi-piece mold designed to shape a glass tube. The one piece of the mold can then be used as a source of intense heat to render the glass malleable and to also contribute to shaping the tube in conformance with the mold. In one embodiment, the heat source includes channels formed throughout the one piece of mold for distributing a gas therethrough with jets of gas emanating from the inner surface of the mold piece for heating the tube to be shaped to a desired temperature. In apparatus embodying the invention, there is no need for a separate torch and for moving the torch during the shaping process. Also, in accordance with the invention, better control of the heat supplied to the tube being shaped is obtained.

Abstract: Apparatus for shaping a selected end region of a hollow cylindrical glass tube includes an internal mold placed within the selected end region for supporting the walls of the tube and controlling the shape of the internal surface of selected end region of the tube, during the period of time heat is applied to the tube and the tube is being shaped. In one embodiment the internal mold has a variable configuration and may be selectively set to an extended (open) configuration or to a collapsed (closed) configuration. With the internal mold set to its extended configuration, sufficient heat may be applied to the selected end region to render it malleable. Then, compression forces may be applied to the exterior surface of the tube to press the inner surface of the selected end region of the tube against the outer surface of the internal mold, causing the inner surface of the selected end region to conform to the outer surface of the internal mold.

Abstract: A high-density, small fiber optic enclosure permits the cross-connection and interconnection of optical fibers, through the use of an open-faced compact layering technique. The optical fiber enters an aperture in the bottom of the enclosure which includes a first section attachable to a wall surface, and a second section connected to the first enclosure section by a hinge. The first enclosure section includes an optical fiber splice holder and a plurality of hooks and clips for holding the optical fibers. The second enclosure section includes a plurality of hooks and clips also. The fibers enter the first section, are connected to the hooks and clips, and cross over to the second section and return to the first section and ultimately pass through an exit aperture in such a fashion as to form a plurality of FIG. 8 layers. If the optical fibers are not shielded, it is possible to use two opposing S-shaped fiber tubes to protect them at the crossover between the first and second enclosure.
