Transformation Point Determination (e.g., Dew Point, Boiling Point) Patents (Class 374/16)
  • Patent number: 10712301
    Abstract: Methods and systems are described herein which allow to determine an icing condition without requiring a wind speed measurement. The methods and systems use two sensing members both being exposed to conditions in an environment. The determination is made based on a capacity of the sensing members to react differently to the conditions to which they are exposed. The conditions can be environmental or controlled. The determination includes measuring a variable indicative of the thermal state of each individual sensing member, and processing the measured values to generate the signal indicative of icing condition. The icing condition can be instrumental or meteorological.

  • Patent number: 9004752
    Abstract: A viable strategy to enhance the bioavailability of poorly soluble drugs is to use amorphous solids in place of the more commonly used crystalline solids in pharmaceutical formulations. However, amorphous solids are physically meta-stable and tend to revert back to their crystalline counterpart. An effective approach to stabilizing an amorphous drug against crystallization is to disperse it in a polymer matrix. The drug's solubility in the chosen polymer defines the upper limit of drug loading without any risk of crystallization. Measuring the solubility of a drug in a polymer has been a scientific and technological challenge because the high viscosity of polymers makes achieving solubility equilibrium difficult and because pharmaceutically important drug/polymer dispersions are glasses, which undergo structural relaxation over time. The invention provides a method based on Differential Scanning calorimetry (DSC) for measuring the solubility of crystalline drugs in polymeric matrices.

  • Patent number: 8348500
    Abstract: A hygrometer and dew-point instrument is provided that is structurally simple while reducing the workload during maintenance. The hygrometer measures relative humidity of a measurement space, and has a main body that encapsulates a working fluid therein and causes a heat-pipe phenomenon. The main body is disposed across the measurement space and an external space spaced from the measurement space by a heat-insulating part and has a temperature lower than the measurement space. A first temperature deriving part derives the temperature of the main body in a section where the working fluid evaporates. A space temperature detecting unit detects the temperature of the measurement space. A computation unit calculate relative humidity of the measurement space based on the temperature of the main body derived by the first temperature deriving part and the temperature of the measurement space detected by the space temperature detecting unit.

  • Patent number: 8292501
    Abstract: A cryogenic turbo-pump with an inducer and a system for detecting an onset of cavitation at the blade tips of the inducer. An IR imaging sensor is used to view the blade tips during operation of the turbo-pump for a temperature drop that indicates the onset of cavitation. The imaging sensor includes a means to vary the image capture rate to that the rotating blade tip will appear to be stationary in order to measure the blade tip temperature. A window is formed in the inducer housing in which the imaging sensor can view the blade tips during operation.

  • Publication number: 20120155505
    Abstract: In a method for detecting the freezing of water within a fuel cell, precise detection can be performed using a phenomenon specific to the time when water starts to freeze to allow a reduction in erroneous activation. Detection at an early stage after the start of freezing is allowed, and hence measures can be taken against an output reduction before the water within the fuel cell completely freezes.

  • Publication number: 20120155504
    Abstract: A method for improved handling of a blended fuel includes obtaining a sample of the blended fuel from a storage tank; cooling the same until the sample separates into phases; and determining a risk that the fuel in the storage tank will separate based on the cooling step. An apparatus for assessing the risk of phase separation of a blended fuel includes a test cavity for holding a sample of the blended fuel from a storage tank; a heat transfer device for cooling the sample in the test cavity; and at least one sensor for indicating when the sample in the test cavity has separated into phases.

  • Patent number: 8201992
    Abstract: New sensors and methods for qualitative and quantitative analysis of multiple gaseous substances simultaneously with both high selectivity and high sensitivity are provided. The new sensors rely on a characteristic difference in energy between the interaction of a particular substance with a catalyst coated heat transfer device (HTD) and a non-catalyst coated (or one coated with a different catalyst) reference HTD. Molecular detection is achieved by an exothermic or endothermic chemical or physical reaction between the catalytic surface of the sensor and the molecule, tending to induce a temperature change of the sensor. Both high temperature and non-destructive low temperature detection are possible. The magnitude and rate of endothermic or exothermic heat transfer from a specific molecule-catalyst interaction is related to molecular concentration.

  • Patent number: 8172457
    Abstract: The invention relates to a method and a sensor for determining the hydrocarbon dew point in a gas, in particular in a gaseous fuel. According to the invention a roughened condensation surface is provided on a planar measurement surface of a transparent body. Light is shone onto the roughened condensation surface through the transparent body and the intensity of the light reflected back into the transparent body is measured. The hydrocarbon dew point temperature can be inferred from changes in the intensity of the light which is reflected back when heating or cooling the condensation surface.

  • Publication number: 20120099616
    Abstract: In a first aspect the invention relates to a sensor system (10) for determining a proximity to icing conditions of an environment. The system includes a sensor having a sensor surface (12) for exposure to the environment, an electrically powered heat pump means (16) for cooling and/or heating the surface (12), and a temperature detector (14) for providing a signal representative of the temperature of the surface (12). An environment temperature is determined, and a processor determines, from the temperature detected by the temperature detector (14) and the environment temperature, a proximity to icing conditions of the environment to which the surface (12) is exposed. In a second aspect of the invention the sensor system includes a power monitor for determining an amount of power required to heat or cool the surface through a temperature indicative of ice formation. The processor determines the proximity to icing conditions from the detected temperatures and the amount of cooling or heating power.

  • Patent number: 8092078
    Abstract: In a method of measuring a temperature value associated with melting, softening or decomposition of sample substances, an array of samples is deposited onto a support tray. The support tray is placed onto a heating device provided with temperature sensing means, the support tray is illuminated, and the array of samples is observed by a imaging device. WNle varying the temperature of the heating device, the image data from the imaging device is fed to an image recording device and temperature values associated with each feed of image data are also recorded. The image data is reviewed to detect changes in the image, such as image intensity, at each or selected sample locations, and the temperature of the heating device at an image change associated with a change in state of a sample is logged. Image processing software may be used to detect changes in the image, for example in the intensity of the image, at each sample location.
