摘要： A method and apparatus is disclosed for correcting errors in a chromatographic analysis wherein the trailing edge of a strong peak interferes with the integration of the trailing peak which follows the strong peak. In one embodiment of the invention two functions of the trailing peak are electrically integrated and summed to produce a correct peak integration. In a second embodiment of the invention the baseline is shifted and the integration of the trailing peak is performed with respect to the shifted baseline to produce a correct peak integration.

摘要： An apparatus and method are provided for measuring the concentration of a light hydrocarbon in a relatively high boiling liquid mixture. A chamber is sealed liquid full of the liquid mixture. The internal volume of the chamber is then increased by mechanical means, causing the liquid to boil adiabatically within the chamber. The absolute pressure within the chamber is then measured and indicates the amount of light hydrocarbon present as compared to previous samplings. In a specific embodiment of the invention the apparatus comprises a chamber with a spring and bellows mechanism for increasing the internal volume of the chamber. In a further embodiment of the invention the input of heat to a distillation column is controlled in response to a signal generated corresponding to the absolute pressure measured in a continuous sequential sampling of liquid from a chosen point within the distillation column.

摘要： Control of a process in response to a process signal which is incrementally altered at periodic intervals is accomplished by performing a simulated differentiation of the process signal prior to use of the process signal as an input to a process controller.
摘要翻译：响应于以周期性间隔递增地改变的过程信号的过程的控制是通过在将过程信号用作过程控制器的输入之前执行过程信号的模拟区分来实现的。
