Assignee:

Corona Optical Systems, Inc. - Lombard IL

International Classification:

G02B 642

US Classification:

385 92, 385 52, 385 88

Abstract:

A method and apparatus are provided for providing an electro-optic signal processing device. The method includes the steps of providing an optically transparent substrate having first and second planar elements with an abutting common edge, the planar elements lying at differing angles with respect to each other about the common edge and a plurality of alignment apertures formed in the substrate. A plurality of optical devices of an optical array are disposed on the first planar element of the substrate, with transmission paths of the optical devices passing directly through the substrate. A signal processor is also disposed on the first planar element of the substrate. An optical fiber holder comprising a plurality of respective optical fibers and guide pin apertures disposed on a first surface of the optical fiber holder is aligned to the optical array using the guide pins and guide pin apertures. Optical signals of the optical devices of the optical array are coupled to respective optical fibers of the aligned optical fiber holder. A printed circuit board having a first surface is attached to a mating surface of the substrates second planar element.

US Classification:

385 92, 385 88

Abstract:

A method and apparatus are provided for providing an electro-optic signal processing assembly. The method includes the steps of providing an optically transparent substrate with a plurality of alignment apertures formed in the substrate, disposing a guide pin in each of the plurality of alignment apertures, providing an optical device with a transmission path of the optical device passing directly through the body of the optically transparent substrate, aligning an optical fiber holder to the optical device using the guide pins and guide pin apertures, and coupling an optical signal of the optical device of the optical array to a respective optical fiber of the aligned optical fiber holder.

Abstract:

Transitions from the 2p. sup. 4 (. sup. 1 S. sub. 0)3s. sup. 2 S. sub. 1/2 state of atomic fluorine to all allowed lower states produces laser emission at six new wavelengths: 680. 7. ANG. , 682. 6. ANG. , 3592. 7. ANG. , 3574. 1. ANG. , 6089. 2. ANG. , and 6046. 8. ANG. Coherent radiation at these new wavelengths can be generated in an atomic fluorine laser operated as an amplifier or as an oscillator.

Appl. No.:

6/153184

Inventors:

John L. Greene - Northbrook IL

International Classification:

E01B 900

US Classification:

238310

Abstract:

An assembly is provided for securing a rail to a supporting tie and includes upper and lower plate members engaging corresponding tie surfaces. The upper plate member is interposed the base of the rail and the tie upper surface. A portion of the upper plate member projects outwardly from the rail base and is apertured. The aperture is aligned with a hole in the tie extending transversely between the corresponding tie surfaces. The lower plate member is provided with a slotted aperture aligned with the tie hole. A resilient clip overlies the upper plate member apertured portion and includes apertured inner and outer sections disposed in resiliently spaced relation. Apertures in the clip sections are aligned with one another and the upper plate member aperture. A lock element is provided having a head end, a distal end, and a shank interconnecting the ends. The distal end has lateral extensions.
