摘要： A piston metering device for the production of a plastic material from at least two flowable reaction components. This device is basically composed of (a) a hydraulic driving mechanism, (b) two piston cylinder units, (c) a mixer head and, optionally, (d) a control device common to at least one of the piston cylinder units. This device permits rapid and simple adjustment of the metering ratio of reaction components by adjustment of throughput. Such adjustment is accomplished by means of regulating elements made of hydraulic motors rigidly coupled to one another.

摘要： The present invention is directed to a process and apparatus for production liquid reaction mixtures. The invention includes a mix head with a mixing chamber which receives reactants through nozzle openings. The key feature resides in placing an impingement surface between at least one of the nozzle openings of the mix head and the mixing chamber itself.

摘要： The instant invention is directed to a method and apparatus for measuring the proportion of undissolved gas in a liquid component for the production of foam materials, particularly, those based on polyurethane. The method is based on the equation of state of ideal gases (Boyle-Mariot Law: P .sup.. V = constant) at constant temperatures. The gas contained in a liquid component charged with gas increases its volume under expansion according to the above equation. The gas expansion causes expansion of the liquid gas mixture. The difference in the volumetric flow rate of the liquid, at two differing pressures, is therefore a measurement of the quantity of gas present in the liquid. The apparatus consists of one volumetric flow rate measurement unit connected upstream of a pressure drop unit, a second volumetric flow rate measurement unit connected downstream of the pressure drop unit and a differential value indicator connected to the first and second volumetric flow rate measurement units.
