  • Method of and apparatus for measurement of the gas loading of a liquid synthetic-resin component
    Patent number: 4581934
    Abstract: A method of and an apparatus for the measurement of the degree of gas charging of a liquid component of a foam synthetic resin such as a polyurethane. The gas-charged liquid component is introduced into a measuring vessel to a height controlled by an overflow so as to be fixed. The degree of charging is then determined from the measured hydrostatic pressure of each column.

  • Apparatus for determining the gas content of a liquid
    Patent number: 4365505
    Abstract: Disclosed are a method of and an apparatus for determining entrained gas content in a liquid, especially a liquid synthetic-resin component adapted to form a foamed or cellular synthetic-resin body. Pressure pulses are applied to the liquid and pressure oscillations therein are detected, the amplitude .DELTA.p and/or the phase position of a peak being detected and evaluated to give the gas content. The determination may be used to control the addition of the gas to the liquid and/or can be displayed to permit operator control of the system.
