Title: Optical analysis method and apparatus having programmable rapid random wavelength access
Inventor: KEMENY GABOR J
IPC: G01N21/47
Filed: 1987-04-27
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE     OPTICAL ANALYSIS METHOD AND APPARATUS HAVING PROGRAMMABLE RAPID RANDOM WAVELENGTH ACCESS         The optical reflectance or transmittance concentration analyzer includes an acousto-optical tunable filter (AOTF) with a pair of crossed polarizers to select one of the tuned monochromatic light beams that pass from a light source through the AOTF.  The AOTF is tuned by a computer controlled digital-to-analog converter through a tunable sweep oscillator.  To obtain rapid wavelength change along with electronic chopping or wavelength modulation, the digital-to-analog converter output is added to the output of a high speed signal generator.  The modulated light is conducted directly or through a fiber optic cable to the location of the optical measurement and impinges upon the sample where it is reflected or transmitted.  The emerging light is collected onto detector (8). The measurement time interval can be distributed among the required wavelengths or wavelength pairs according to an unequal scheme to decrease the error of the result in a calibration equation.  The apparatus is particularly adaptable for use as an on-line concentration monitor in industrial process control because of its stability, efficiency and ability to perform quick analyses.

Abstract: METHOD AND APPARATUS FOR MOLDING              AND CASTING USING GATED DIES               ABSTRACT OF THE DISCLOSURE           A method and apparatus for molding and casting ophthalmic lenses includes a front surface die and a back surface die slidably and removably received in the bore of a molding or casting apparatus.  Molding or casting compound is introduced by conventional means between the two dies, and the dies are urged together to impress the die surfaces on the compound as the compound is cured by thermal or chemical means.  At least one of the dies includes at least one gate channel formed in the edge thereof parallel to the axis of the bore and extending from the optical forming surface to a point adjacent to the opposite, external die surface in compression molding, the gate channel comprises a vent through which excess molding compound is discharged from the molding cavity as the dies are urged together.  As the gated die is fully inserted in the bore, the gate channel opening to the exterior is sealed, thus limiting the discharge effect and controlling the thickness of the molded part.  In casting, the dies are partially inserted in the bore, and the gate channel serves as an injection channel to introduce the casting compound into the casting cavity.  The dies are urged together in the bore, the gate channel first serves to vent excess casting compound from the casting cavity.  Full die insertion in the bore causes the gate channel opening to the exterior to be sealed, thus limiting the discharge effect and controlling the thickness of the cast part.
