Title: Howard J. Sloane: Innovator in Spectrophotometry
Introduction
Howard J. Sloane is a notable inventor based in Fullerton, CA. He has made significant contributions to the field of spectrophotometry, holding a total of 2 patents. His work focuses on enhancing the functionality and accuracy of spectrophotometric devices.
Latest Patents
Sloane's latest patents include a "Common beam aperture for dual beam spectrophotometers." This invention addresses the 'aperturing effects' that occur when a sample holding aperture is integrated into the sample beam of a conventional dual beam spectrophotometer. It allows for the examination of very small samples by compensating for undesired variations in the baseline output of the spectrophotometer. The apparatus features a second aperture that is optically equivalent to the sample aperture, strategically located at a slit image point within the common beam portion of the spectrophotometer.
Another significant patent is the "Spectrophotometer having independently controlled chart scale expansion." This invention introduces a variable chart format system for a recorder with a chart printout. It includes a manually selectable switch that allows for simultaneous control of the abscissa and ordinate formatting, independent of the scale expansion circuitry. The abscissa formatting is digital and operates in response to a programmable clock, while the ordinate formatting is analog, ensuring precise control over chart formatting.
