Abstract: A method and an apparatus for forming a hemispherical convex mirror surface on the end of a ferrule or optical fiber connector efficiently and accurately. The apparatus has a grinding wheel having a concave work surface, a tool for correcting the shape of the work surface, a stage for bringing the tool into contact with the wheel, a mechanism for causing the end of the ferrule to contact the work surface, and a mechanism for displacing the axis of the ferrule from the center of the curvature of the arcuate section of the work surface. After the axis of the ferrule has been displaced from the center of the curvature, the ferrule is caused to contact the work surface and roughly ground thereby. Subsequently, after the ferrule axis has been brought into alignment with the center of curvature, the ferrule is sequentially finished from the tip to a preselected point thereof.

Abstract: The present invention relates to an improved blast cleaning apparatus for cleaning coiled wire with abrasive cleaning material. A prior art apparatus for blast cleaning wires comprises an elongated boom provided with annular splitters for longitudinal separation of wire coils and metal lifters for radial separation of wire coils to expose substantially all of the surface of the wires to the abrasive cleaning material. Due to the hardness of the lifters, some abrasive cleaning material becomes embedded in the wire and causes problems with subsequent processing steps. The present invention provides a blast cleaning apparatus having resilient lifters which overcome this and other difficulties. Preferably, the lifters according to the present invention are made of polyurethane and are used in combination with a conventional boom with or without splitters.

Abstract: A wire coil support in the form of a boom for a wire coil blasting apparatus wherein abrasives are thrown at or blasted at a coil wire carried by a wire support in the form of a boom. When the diameter of the wire in a given weight coil decreases, the number of coils in the coil greatly increases. As a result, the number of rows of coils increases and makes it more difficult to separate the individual coils for the reception of an abrasive blast. By modifying the boom to incorporate radial lifters, the coils may be separated, not only longitudinally, to provide for a more efficient abrasive blasting operation.
