Abstract: Coated glass containers having a surface cured composition which is the reaction product of at least one ethylenically unsaturated monoene, a polyene and a curing initiator. The coating is bonded to the exterior or interior surface of a glass container to increase hardness and strength.

Abstract: An optical fiber cleaving tool is disclosed having a frame with means for holding a fiber optic connector installed intermediate the length of an optical fiber against lengthwise movement, thereby providing a fixed fiber axis. A pair of selectively operable clamps are supported on the frame for engagement with the fiber at a location spaced from the connector, the clamps are further supported for slideable movement parallel to the fiber axis for placing a tension along the fiber axis to slightly enlongate the fiber. A pair of opposed, selectively operable fiber engaging members are supported on the frame for opposed engagement with the fiber, at least one of the members having a sharpened blade for scribing the fiber, the force placed on the fiber by one member being equal and opposite to the force placed on the fiber by the other member during scribing of the fiber for subjecting the fiber to zero torsion and zero bend stress.

Abstract: A fiber optic treatment probe (10) delivers laser light from a laser light source (11) through a diffuser (26). An input end face (30) of the fiber is angled with respect to a plane (36) normal to an optical axis (18) of the fiber. The end face angle is selected to excite desired modes of the fiber without exceeding the critical angle of the fiber, thereby producing a desired light output from the diffuser.
