Abstract: ABSTRACT OF THE DISCLOSURE         An improved flame photometry detector to give direct quantitative detection of molecules containing sulfur by:         - the total combustion of the mixture to be analyzed so as to transform the sulfur into sulfur oxide (primarily SO2);         - the linearization, by an electronic device, of the signal supplied by the electrometer, in series with the photo-multiplier of the detector, prior to recording (this results in the proportionality of the recording to the number of sulfur-containing molecules detected); and preferably the provision of a leakage flow beyond the burner and in front of the detection so as to avoid saturation of the detector.   These improvements can be applied to the analysis of a hydrocarbon mixture and of sulfur compounds which have been previously eluted on a chromatographic column.

Title: Measurement conversion and visual display instrument
Inventor: HIRD EDWIN A
IPC: G01B7/02
Filed: 1977-07-05
Granted: 1981-12-29
Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates to a measuring instrument.  There has been a requirement for a measuring instrument which is compact and easily usuable, and which has the capability of measuring directly a given distance and converting that measurement into another proportional measurement.  Various devices have approached the solution to this problem by providing a system for machine tool equipment in the numerical control field, converting signals from a punched tape in the metric system to the U.S. system.  While this approach provided an electronic means to accomplish the conversion, no attempt was made to introduce a complete analog-to-digital system into a compact unit wherein a direct measurement could be converted and displayed as a visual readout in one or more different proportions or measurement systems, such as is accomplished by the present invention.  In a preferred embodiment, the present invention has the appearance of a conventional steel rule tape.  An extensible measuring unit, usually in the form of a conventionally curved steel tape, is extensible outwardly from the case to provide an accurate means for measuring between two given points.  An electrical switch is turned on either before or after a measurement begins and a second switch is actuated to select the system of measurement to which the measure of distance is to be related.  As the tape is withdrawn, the distance is measured in one measurement system, converted as necessary, and instantly displayed in the same or a second measurement system.
