II Vleeting eports The Pittsburgh Conference The conference programme this year encompassed over 900 scientific and technical papers. As has become the custom, many are pseudotechnical presentations by instrument company staff describing their latest developments. With the developments in microprocessor applications, many of the papers can be broadly classified as automation, and as such, a complete summary of these is not possible. This report des- cribes a cross section of papers in this category. Janule [1] described the development of a prototype instrument for measuring surface tension of emulsions and its subsequent commercialisation. The technology used is a refinement of the maximum bubble pressure method. Results are stable and repeatable to within + 1/2%, with the direct digital control being provided through the computer inter- face. De Souza [2] described how the use of continuous or automated analytical instruments cuts back on manpower requirements and gives real-time analysis. However, rigid maintenance becomes necessary because of the complexity in operating some of these sophisticated pieces of equipment. Analytical devices for measuring sulphur gas concentrations in gas streams are available on the market, the most notable of these are based on the principles of flame photometry, ultra-violet spectroscopy and electrochemical sensing. The advantages of each group were discussed. Detectors for measuring carbon dioxide, oxygen, nitrogen oxides plus particulates were also discussed with reference to their application to the process industry. A continuous oxygen analysis system which has operated satisfactorily on coke oven gas sampled immediately after the booster pumps in the coke plant was described by Manka [3]. The gas glows at sufficient pressure without the use of pumps through a moisture trap, a naphthalene removal system, and a filter to an oxygen analyser which depicts the oxygen content as a peak on the recorder each time an oven is charged with coal. Two methods for chargi
