Abstract: The invention relates to a method and a device for monitoring, also permanently and automatically, temperature distributions and/or temperature anomalies on the basis of distributed fiber-optic temperature sensing as well as to the use of such methods. According to the invention the detection of local temperature extremes, i.e. minimums or maximums, in view of the evaluation is performed by an evaluation without numeric derivations. With the device for monitoring ascending and supply pipes surrounded by an annular space it is possible to check the safety of pressurized installations, particularly in the field of low-pressure gas storage, in a cost-efficient manner. Moreover, the position of an underground watershed or respectively the direction and flow rate of the flows in flooded drift sections can be determined on the basis of fiber-optic temperature measurements.

Abstract: A lens eccentricity adjusting device includes a circular opening formed on a lens frame, a lens being fitted into the circular opening; at least three flat countersunk head screws each screwed into the lens frame, the flat countersunk head screws including a male thread portion that is screwed into the lens frame and a head portion having a tapered surface; and at least one elastic member positioned between the flat countersunk head screws and the rim of the lens. The eccentricity is adjusted by deforming at least one elastic member via pressure of the tapered surface of a corresponding flat countersunk head screw on the rim of the lens, in accordance with an amount the corresponding flat countersunk head screw is screwed into the lens frame, so that the lens is moved in the circular opening in a radial direction.

Abstract: A system and method for performing localized mechanothermal analysis with scanning probe microscopy (“MASM”) is disclosed. In a preferred embodiment an image of the surface or subsurface of a sample is created. A localized region of the sample is selected from the image. Using a scanning microscope, an active or passive thermal probe is positioned at the selected region. A temperature ramp is applied to the localized region. In addition, a dynamic or modulated stress or strain is applied to the localized region. Force data resulting from the applied temperature and stress or strain is collected and processed to produce a graph or fingerprint of the dynamic mechanical and/or calorimetric properties of the selected localized region.

Abstract: A temperature detector provides a base for supporting a stand which includes a cradle having an elongated open channel for supporting a heated curling iron. The cradle is resiliently carried on a post so that the cradle can move up and down over the terminating end of the post. The terminating end of the post includes a thermocouple which projects into and through an orifice in the cradle when the cradle is in the depressed or down position. Thus, the temperature of a weighted heating iron, for example, residing in the cavity of the cradle can be sensed by the thermocouple. The base includes support for a visual read-out display of the temperature sensed and circuit means interconnects the display with the thermocouple. The thermocouple is protected from damage by the weighted object in the cradle by providing a resilient mount for the thermocouple within the post.
