Abstract: A fixture for use in a fiber curl measurement assembly has a fiber guide plate upon which are disposed a pair of fiber locating and centering rods which form a V-groove for containing the fiber, which is free to rotate within the groove. A reference plate having a transverse reference edge in space from the downstream end of the V-groove a distance sufficient for fiber curvature to be measured during rotation. A rotating stage under control of a motor has a rotatable plate upon which rests, and is held, a fiber clip for containing the fiber to be measured. The rotating stage is oriented at a vertical angle to the plane of the rods and V-groove, and the fiber is threaded through a bearing block into the V-groove. The bend thus created in the fiber is such that a downward force is created on the fiber to hold it within the V-groove. Thus, where the rotating stage is rotated by the motor, the fiber within the groove is rotated so that curl measurements may be made.

Abstract: A fiber splicing assembly for making butt splices between fiber ends has a horizontal plate member having at least one groove therein containing a pair of fiber guiding rods, adjacent opposite ends of the groove are first and second ramp members which slope toward the guide rods at an angle to the plane of the plate member. Each ramp member has fiber holder guiding means thereon to guide a fiber within a holder toward and in to the V-groove formed by the guide rods. Magnetic means maintain the rods in a relatively fixed position, and the slope of the ramps is such that the bend created in the fiber tends to create a downward force on the fiber, forcing it into the V-groove.The diameter of each of the guide rods is such that the fiber is guided into the V-groove despite undesirable bends in the free end of the fiber.

Abstract: A display board construction including standards for mounting on a supporting surface, a plurality of carrier members extending between the standards generally normally oriented with respect thereto and connector assemblies removably and slidably mounting the carrier members on the standards. A display strip is removably carried in the carrier members to record data thereon and a dispenser is provided to refill the members with the strips.
