Abstract: Method of producing an optical transmission line is provided which comprises forming, on the inside wall of a highly transparent cylindrical medium, a highly transparent deposition layer having a refractive index higher than that of said cylindrical medium to form a double-layered cylinder; coaxially inserting into said cylinders, a highly transparent round rod medium having the same refractive index as that of said cylindrical medium; then melting them under heating and drawing so as to reduce the diameters thereof thereby forming a fiber comprising a double-layered cylindrical medium and round rod medium integrated coaxially without clearance between them.

Abstract: A preform for later use in drawing optical fibres is made from an outer tube of cladding glass by spinning molten glass in a mold about a horizontal axis. As the mold is cooled, a lower specific gravity high refractive index core glass is inserted into the bore of the cladding glass tube. The mold is again centrifuged, heated to melt the two glasses and cooled to stabilize the glass interface and promote diffusion. The required relationship between specific gravities and refractive indices is obtained by using similar glass compositions. The core glass may contain calcium oxide and sodium oxide while the cladding glass includes barium oxide and potassium oxide.

Abstract: An improved method is described for the production of glass by the decomposition of a mixture of glass forming compounds in the flame of a combustible gas to form an oxide mixture which is vitrified. The improvement includes generating vapors from a decomposable solid material that has a vapor pressure equal to 5 mm. Hg at a temperature above ambient temperature but not over 500*C. The vapors are generated by suspending the material in finely divided form in a heated chamber and passing a carrier gas through the material. The method is especially useful in the production of modified vitreous silica glasses.

Abstract: A MOLTEN LAYER OF CLADDING GLASS IS SUPPORTED ON A MOLTEN LAYER OF CORE GLASS AND AN ELONGATED GLASS MEMBER COMPRISING CLADDING ON A CORE IS DRAWN FROM THE FREE SURFACE OF THE UPPER LAYER OF GLASS. THE ELONGATED MEMBER IS COOLED JUST ABOVE THE FREE SURFACE OF THE UPPER LAYER OF MOLTEN GLASS. THE ELONGATED GLASS MEMBER MAY BE DRAWN TO FORM A CLAD FIBER FOR USE IN FIBRE OPTICS. BAIT IS LOWERED TO THE MOLTEN GLASS TO INITIATE DRAWING OF THE ELONGATED GLASS MEMBER.

Abstract: A process for heat sealing together two preformed glass articles preferably adapted to be nested one within the other by a technique which envisions a precise and careful conditioning and treatment of the surfaces to be heat sealed, coupled with temperature control and impressment of particular low pressure conditions as in combination promote the heat sealing joinder of the surfaces and consequently the articles together in a manner as is yieldative of an ultimate produce in which the optical as well as other properties of the preformed glass, as imparted by the compositional makeup thereof, is relatively unimpaired and therefore of high quality. This method is accomplished by a device having an elongate compartment having heaters located outside, with a base to hold the glass cylinder which has an opening connected to a vacuum source at the bottom of the compartment.
