Abstract:
A decorative structure having a plurality of flexible optical fibers each having a light-receiving end and a light-emitting end. A structural rod which may be flexible or rigid is positioned adjacent a portion of the optical fibers. A wrapping is provided for securing a portion of the optical fibers to the structural rod. The light-receiving ends of the fibers are positioned near the light path of a light source for illumination of the optical fibers. In addition, a plurality of structural rods may be surrounded by the optical fibers adjacent the lightreceiving end of the fibers. A plurality of side branches can be formed from a main branch with each side branch formed of a plurality of optical fibers and one of the rods extending from the main branch of the structure.
Abstract:
A decorative structure comprising a hollow body enclosing an electric lamp and carrying a spray of optical fibers laterally thereof. The hollow body is formed of separate but matinglyengageable anterior and posterior members, each defining opposing coincident annular surfaces, an opening being formed through the coincident surfaces at the juncture of the anterior and posterior members to receive the bundled ends of an optical fiber spray. In one embodiment, the anterior member is coniform. In another embodiment the anterior member is spheriform and the structure incorporates a plurality of optical fiber sprays.
Abstract:
A decorative structure in which tiers of flared optical fibers or the like extend vertically from a base therefor, and a backstop is secured adjacent the flared portions of the fibers.
Abstract:
A method for making contact lens blanks comprising the fixing of optical lens material to an accurate shaft having a concentric axis of rotation and placing the shaft in a rotary machine and machining an optical interface configuration on the optical material fixed to the shaft so that the inter- face configuration is concentric with the axis of the shaft, then placing the shaft and the optical material fixed thereto in a mold and then placing hardenable material on said optical configuration in said mold and allowing the hardenable material to harden and become fixed to the interface configuration; removing the shaft from the mold and machining the materials thus fixed to the shaft into a lens blank by machining the periphery of the lens blank concentric with said axis of said shaft and by machining opposite ends of said lens blank normal to said axis; the method also relating to the machining of a second interface configuration on the first mentioned hardenable material and subsequently casting or placing a second hardenable material over the second interface configuration in accordance with the aforementioned molding method, then machining all three optical materials into a lens blank with the periphery and opposite ends of the blank accurate in relation to the axis of the shaft such that the periphery of the blank is concentric with the axis of the shaft and opposite ends of the blank are normal to the axis of the shaft.
Abstract:
An optical fiber display for use within a fish tank or the like for decorative or lighting purposes. A plurality of optical fibers are disposed below the liquid level of the tank and the light receiving ends of the fibers are secured in communication with a light source. The light source includes a light bulb and electrical connection for the bulb which is separated from the liquid. In particular embodiments the light-receiving fiber ends are carried on one side of a wall of the tank while the light bulb and electrical connection are carried on the other side of the wall.
Abstract:
An extrusion method for organic polymer optical fibres in which an elongate, solid body of organic polymer material is moved through a crosshead die wherein organic polymer material is extruded to intimately adhere to the surface of the body, and the clad body is then drawn to an increased length. At all times from adherence of the cladding material to the drawing step, the clad body is maintained at a temperature at or above the softening point of the cladding material or the body material.
Abstract:
An illuminated globe carrying sprays of optical fibers in which a hollow globular body is formed with openings for receiving the bundled ends of a plurality of optical fiber sprays. An electric lamp within the hollow body illuminates the optical fibers.
Abstract:
An adapter is provided whereby a spray of optical fibers can be readily connected or disposed in proximity to a light source by means of an acylindrical casing therefor. A plurality of optical fiber sprays are connected for illumination by the light bulbs on a string of light bulbs which may then be used for decorating a Christmas tree or the like.
