Abstract: A high throughput workstation includes: a sample deposition and annealing robot, a pan/sample weighing robot, and a thermal analyzer equipped with autosampler and data analysis system. After deposition, the solvent can be removed and multiple samples annealed simultaneously in a controlled manner. The sample pans are weighed before and after the samples are prepared using a robotic weigher. The high throughput workstation facilitates analysis of thermal properties of samples obtained via parallel plate reaction (PPR) in substantially less time than corresponding manual techniques.

Abstract: An improved method is provided for determining when a set of multivariate data (such as a chromatogram or a spectrum) is an outlier. The method involves using a procedure such as Principal Component Analysis to create a model describing a calibration set of spectra or chromatograms which is known to be normal, and to create residuals describing the portion of a particular spectrum or chromatogram which is not described by the model. The improvement comprises using an average residual spectrum calculated for the calibration set, rather than the origin of the model as a reference point for comparing a spectrum or chromatogram obtained from an unknown sample. The present invention also includes separating a complex set of data into various sub-parts such as sub-chromatograms or sub-spectra, so that outliers in any sub-part can be more readily detected.

Abstract: An improvement upon cylindrical MIR element cells of the type that have a single seal at the openings of the cell body through which the cylindrical MIR element extends. The improvement is: (1) to position an additional seal between each such opening and the cylindrical MIR element so that there is a sealed space between the second seal and the original seal at each such opening; and (2) to position at least two passageways through the body of the cell, each such passageway in fluid communication with each of the above formed sealed spaces so that any leakage of a sample past the original seal is vented from the cell via one of the passageways. In a highly preferred embodiment of the present invention the portion of the cell body surrounding each such opening is made demountable and is provided with additional passageways and seals so that a purge fluid can be flowed through the passageways to a flow through detector to detect any leakage of a fluid sample past one of the original seals.

Abstract: Process for the preparation of asymmetrical alkaline earth metal organoborates and organoaluminates represented by the formula I: ##STR1## and asymmetrical alkaline earth metal organoarsenates and organophosphates represented by the formula II: ##STR2## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are independently selected from alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, and cyano with the proviso that R.sub.1 -R.sub.6 are not all the same.

Abstract: Alkaline earth metal anode cells having an intercalation cathode, a nonaqueous liquid electrolyte comprising (a) an organic solvent, for instance, an ether, an ester, a sulfone, an organic sulfide, an organic sulfate, a tertiary amine, an organic nitrite, and an organic nitrate, and (b) at least one of an electrolytically active alkaline earth metal salt comprising an organometallic alkaline earth metal salt represented by the formula: ##STR1## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are radicals independently selected from the following groups: alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, allyl, heterocyclic alkyl, and cyano, with the proviso that R.sub.1 -R.sub.6 cannot be all alkyl or all aryl and triarylalkylborate or aluminate anions, and trialkylarylborate or aluminate anions are excluded and M represents an alkaline earth metal.

Abstract: A method of preparing a supported catalyst of a gold-silver alloy useful for making ethylene oxide by applying a gold salt to a suitable support, reducing it to gold metal, then applying a silver salt and reducing it to silver, thereby forming a gold-silver alloy by diffusion, on the support.
