Abstract: An optical fiber or similar article is coated by directing the fiber through a spherical mixing vessel. Two silicone RTV components are directed by means of an annular feed mechanism into the mixing vessel at predetermined flow rates. The motion of the fiber directed through the vessel produces a churning or agitation of the silicone components to uniformly and homogeneously coat the fiber with the mixed components and provide a protective elastomeric coating about the fiber.

Liquid coating material is introduced into the passages, the coating die serving to determine the thickness of the coating which is ultimately formed upon the waveguides.

Abstract: A method and apparatus for treating timbers, such as railroad ties and the like, which comprises at least one pressure sealed tube or pipe filled with the treating fluid normally utilized for treating timbers, and of a size for receiving the timbers in sequential end-to-end relation for longitudinal movement therethrough.

Abstract: A filiform workpiece such as a metal wire is advanced at high speed, after passage through several pretreatment baths, in a vertically upward direction through a closed-ended nozzle of a crucible by way of a lower inlet aperture and an upper outlet aperture of that nozzle which is completely filled with a thermally fusible coating material (e.g. zinc). A guide tube adjustably seated in the inlet aperture has an inner diameter substantially equaling that of the workpiece to be coated whereas the outlet aperture, formed by a collar of a substance which is not wettable by the coating material, has a diameter about two to three times as large. A short residence time of less than 5.multidot.10.sup.-2 second for any given point of the workpiece in the molten mass holds down the temperature of the workpiece and results in rapid hardening of the coating material upon emergence from the bath.

The core is thereafter passed through a sizing die into a cooling chamber which solidifies the compound in and around the core. The cable core is thus conditioned for the subsequent application of sheathing materials thereto, for example, core wrapping and/or armor sheathing.
