  • Patent number: 4644103
    Abstract: In activating a unit for monitoring a remote instrumentality, a tone-responsive circuit operates in accordance with an established duty cycle wherein, for a major portion of each cycle, current is drawn from the telephone lines servicing the system at a rate which is within the range permitted by prevailing telephone regulations, to charge a capacitor over time, and wherein, for a minor portion of each cycle, the charge stored by the capacitor is used to briefly operate a tone detection circuit which is capable of determining whether or not the remote instrumentality is being interrogated. If no such tones are detected, the circuit continues its periodic operation as previously described. If tones indicating a desired interrogation are detected, the tone-responsive circuit activates the monitoring unit which is used to poll the instrumentality.

  • Patent number: 4602870
    Abstract: A method and apparatus for determining the presence or absence of a pour point depressant additive in hydrocarbon liquids includes cooling a sample of the liquid at a predetermined cooling rate from a temperature substantially above the cloud point temperature of the sample liquid to a temperature substantially below the cloud point temperature of the sample liquid. The points on the cooling rate curve for the sample at which a deflection of the curve begins and ends is determined and the time interval between the beginning and ending points of the cooling rate curve is computed. This computed time interval between the beginning and ending points is compared to a reference time interval such that if the reference time interval is less than or greater than the computed time interval between the beginning and ending points on the cooling curve, the presence or absence, respectively, of a pour point depressant additive in the sample is determined.

  • Patent number: 4601587
    Abstract: A freezing point method and device (10) are disclosed. The method and device pertain to an inflection point technique for determining the freezing points of mixtures. In both the method and device (10), the mixture is cooled to a point below its anticipated freezing point and then warmed at a substantially linear rate. During the warming process, the rate of increase of temperature of the mixture is monitored by, for example, thermocouple (28) with the thermocouple output signal being amplified and differentiated by a differentiator (42). The rate of increase of temperature data are analyzed and a peak rate of increase of temperature is identified. In the preferred device (10) a computer (22) is utilized to analyze the rate of increase of temperature data following the warming process. Once the maximum rate of increase of temperature is identified, the corresponding temperature of the mixture is located and earmarked as being substantially equal to the freezing point of the mixture.
