Filed:

Sep 13, 2001

Appl. No.:

09/953007

Inventors:

George C. Schloemer - Longmont CO
Danuta A. Schloemer - Longmont CO
Jeffery L. Davis - Berthoud CO

Assignee:

Prodemex, S.A. DE C.V. - Los Mochis

International Classification:

C07C 4500

US Classification:

568347, 568348, 568362, 568374

Abstract:

A method of preparing -carotene derivatives such as canthaxanthin and astaxanthin is described. The method employs an in situ system to generate hypobromous acid as the oxidizing agent using a salt of sulfite, hydrogen sulfite or bisulfite in combination with a bromate salt. Astaxanthin and canthaxanthin are obtained in good yield with a significantly reduced reaction time.

US Classification:

702104, 356601, 356610, 356625, 382100, 702 85, 702167, 702187, 702189

Abstract:

This disclosure provides for an impression scanner system having improved calibration having a housing and a calibration plate of known geometry. The calibration plate has a plurality of different shapes thereon. The system also has a radiation source for emitting radiation towards the shapes on the plate and a surface for reflecting images created by the radiation on the shapes. A sensor for receiving the images of the shapes as the plate moves relative to the housing is also provided. A processor compares known geometry of the plate to the images received by the sensor and calibrates the sensor based upon the known geometry and images to reduce system aberration and distortion.
