Abstract: Optical-fiber trunks to be spliced are inserted into opposite ends of a downwardly converging longitudinal groove formed at the bottom of a channel member and are held in position by resilient tongues extending into that groove from an overlying retaining member. The latter, made of sheet metal, may be integral with the channel member but could also be a polygonal jacket enveloping an array of channel members accommodating individual fibers of an optical cable to be spliced. Instead of individual channel members so arrayed, an elongate body with several throughgoing channels and associated retaining elements may be used for cable splicing.

Abstract: A method of manufacturing dichroic antenna structures, which makes use of projector mounted on the mobile arm of a computer-controlled machine to project the shape of selective antenna elements on the surface of an insulating layer, clad with a metallic layer covered in turn with a photographic emulsion. Development and chemical etching of the exceeding conductive parts are then carried out.

Abstract: An elongate light conductor of circular or other cross-section is continuously produced by depositing, in a vacuum chamber, a powdered glassy (i.e. vitreous or vitrifiable) material upon the upper end of a descending rod of like material while training a stream of doping ions upon the same end. Vitrification may be assisted by an electron beam, also trained upon the powder-receiving rod end, and/or by thermal treatment of the rod leaving the vacuum chamber. The lower end of the rod is softened in a furnace from which a vitreous strand of reduced cross-section is continuously drawn through an orifice and wound upon a mandrel.
