摘要： Water activity measurement systems and methods for determining water activity of material samples in a test environment under controlled temperature and pressure conditions. The gas pressure in a test chamber is reduced or held constant while sample temperature is simultaneously tracked. The water activity of the sample can be determined by detecting the boiling point of the sample, at reduced pressure, over time, and calculating water activity using the atmospheric pressure and the saturation vapor pressure at the boiling temperature. The boiling point can be determined by observing an inflection point in the sample temperature over time, and the pressure and temperature at the onset of boiling can be determined at an intersection of trend lines extending from substantially linear intervals of temperature recordings over time.

摘要： This invention relates to a method for rapidly determining weight and volume percent true boiling point curves for crude oils and fractions thereof. The method involves at least a partial separation of the crude oil or fraction into constituent chemical components, obtaining mass spectra of the chemical components, correlating retention time windows with boiling points for standard hydrocarbon mixtures, and converting the total ion current obtained from the mass spectra for selected components to weight and volume percent true boiling points by comparison with data obtained from a standard crude oil or fraction thereof.

摘要： A method and device are disclosed for determining and checking a state or condition of a hydraulic fluid contained in a brake system, including a state of hydration and/or age such that the fluid boiling point is reduced. The boiling point or a characteristic value of the fluid which depends on the boiling point, on the one hand, and the instantaneous temperature value of the fluid, on the other hand, are measured by means of sensor elements. These two values represent a range of permissible comparative temperature values, including a thermal reserve which is within that same range and is determined for further permissible heating of the fluid. A warning signal is released when a predetermined minimum value of the thermal reserve is reached. The sensor elements have hollow spaces with open walls permitting fluid flow-through and have such a design as to ensure that, after heating-up, there comes about a stable cellular convection in a temperature range lying below the boiling temperature. The cellular convection is used as an indication of the condition or the state of the fluid.

摘要： A semi-quantitative method for determining the amount of water in contaminated oil samples wherein a small sample of contaminated oil is placed in one or more compartments of a container. An equal size sample of reference oil of the same composition as the test oil, but containing a known quantity of water, is placed in one or more compartments of said container. The container is then heated rapidly and bubbles formed in the contaminated oil are compared with bubbles formed in the reference oil, thereby bracketing the water content rapidly (less than 5 minutes) with reasonable accuracy.

摘要： A monitoring system for determining the volumetric percentage of liquid nitrogen in a quantity of liquified natural gas (LNG) whose composition of liquified hydrocarbon gases is known, and which is stored at atmospheric pressure. The system includes a device, such as a temperature-dependent resistor connected to a power source, for producing an electric signal proportional to the temperature of the liquified gas. This temperature signal is subtracted from a reference signal which is equal to the temperature signal when the liquified natural gas does not contain any nitrogen, and which can be produced by a device such as a precision resistor connected to the power source. The differential signal output of the temperature and reference signals will be proportional to the volumetric percentage of nitrogen in the liquified natural gas, and a standard readout device, such as a voltmeter, can be calibrated to read the volumetric percentage of nitrogen from this differential signal.
