摘要： Disclosed is a single mode optical waveguide fiber designed for use in high performance telecommunication systems. The novel core profile design improves bending performance to provide enhanced resistance to adverse environments. Total dispersion over an extended wavelength window is maintained low by placing the zero dispersion wavelength above the upper limit of the operating window. In addition, cut off wavelength is increased to just below the operating window. Ease of manufacture is retained as is very low waveguide attenuation.

摘要： Disclosed is a single mode optical waveguide fiber having a core refractive index profile in which the profile parameters are selected to provide an attenuation minimum. A set of profiles having the same general shape and dimensions is shown to have a group of profiles contained in a sub-set which exhibit a minimum of attenuation as compared to the remaining members of the set. The members of the sub-set have been found to have the lowest effective group index, ngeff, and the lowest change in &bgr;2 under waveguide fiber bending.

摘要： A model railroad car coupler assembly comprises a coupler with an upper shank having a coupler knuckle at a distal portion and a flat proximal portion, a lower shank having a coupler thumb at a distal portion and a flat proximal portion, and a coil spring terminating in first and second end portions, with a first turn of the coupler spring interlocked with the upper shank and a second turn interlocked with the lower shank. A mounting box has a circular mounting post that accepts circular openings in the shanks permitting them to rotate relative to each other between a closed coupled position and an open uncoupling position. The spring end portions engage the mounting box to bias the shanks into their coupled position. The knuckle carries a ferrous actuating pin that cooperates with a magnetic pad along a track to rotate the upper shank into its open position.
