Patent number: 5327779Abstract: Disclosed herein is an apparatus and process for determining the vapor pressure of materials in a mixture at relatively low vapor pressures by a gas saturation procedure. The process comprises passing an inert gas over a sampled material at a controlled flow rate to create a vapor of the sampled materials that may be collected and analyzed. Of particular importance, this method and apparatus provides a means of collecting vaporized samples over an extended period of time and, therefore, allows even minor components of mixtures to be considered in the final vapor pressure analysis. The apparatus also includes a means for determining whether sampled material has progressed as vapor beyond the means of collecting the sampled material.Type: GrantFiled: September 24, 1992Date of Patent: July 12, 1994Assignee: Ethyl CorporationInventors: Robert N. Sanders, Robin P. McCarthy

Patent number: 4970891Abstract: The apparatus of this invention provides an improved thermal conductivity detector for determination of low levels of gaseous impurities vaporized from solid samples. In particular, a hydrogen impurity vaporized from solid polysilicon beads can be determined down to a detectable limit of about 0.1 ppm by weight. The improvement is comprised of a syringe injection pump for calibration of the instrument, a computer for controlling the syringe infusion pump and for calculating the analytical results, and means for controlling pressure and mass flows of the gas streams.Type: GrantFiled: December 26, 1989Date of Patent: November 20, 1990Assignee: Ethyl CorporationInventors: Donald R.

Patent number: 4908218Abstract: Egg shell quality, egg shell thickness or egg specific gravity are improved, and/or the number of shell-less eggs reduced, when laying poultry is fed a diet comprising a zeolite such as zeolite A and a reduced chloride content. The chloride content of the diet can be below the level previously considered required. Thus, for chickens, both layers and broiler breeders, the chloride content can be below 0.15 percent. The level of zeolite A can be from about 0.25 to about 4.0 weight percent, more preferably from 0.75 to about 1.5 weight percent.Type: GrantFiled: January 19, 1988Date of Patent: March 13, 1990Assignee: Ethyl CorporationInventors: Sebastian M. Laurent, Robert N. Sanders
