Abstract:
A temperature monitoring method and apparatus (10) for monitoring the temperature within a mass of organic matter (36) moved through a composting vessel (12). An elongated, stationary probe (82) extends through the vessel (12) from one end toward another end thereof. A plurality of temperature measuring devices (83) are mounted along the probe (82). The probe (82) may extend through a compaction ram (30) and be provided with a sleeve (108) for accommodating movement of the ram (30) relative to the probe (82). A decoupling device (116) provides for decoupling of the probe (82) from a mounting base (106) and an extraction device (114) permits the probe (82) to be extracted from the vessel (12) for replacement thereof. The probe (82) provides a method of monitoring temperature in the mass (36) and a method of composting by monitoring temperature in the mass (36) and regulating the temperature of the mass (36) in reponse thereto.
Abstract:
In some examples, a method comprises sensing a temperature of a plurality of sub- regions of a portion of a layer of build material in an object generation apparatus. A frequency distribution of sub-region temperatures may be derived therefrom and it may be determined whether the frequency distribution is bimodal. If the frequency distribution is not bimodal, a build material temperature zone is identified. If however the frequency distribution is bimodal, a fusing build material temperature zone and a non-fusing build material temperature zone are identified. The method may further comprise determining a nominal temperature of the at least one identified temperature zone.
Abstract:
An alternating current impedance-estimating section (106) estimates an alternating current impedance (Rh) of the secondary battery based on electric current (I) and voltage (V) of the secondary battery detected when a ripple generating section causes a ripple current to flow in the secondary battery. A temperature estimating section (108) estimates the temperature (T) of the secondary battery based on the alternating current impedance (Rh) estimated by the alternating current impedance-estimating section (106) with the use of the relation, obtained in advance, between the temperature (T) of the secondary battery and the alternating current impedance (Rh) of the secondary battery at a ripple frequency.

Abstract:
The invention relates to a method and a device for measuring the temperature in pre-selected locations of a line or a line bundle and to a vehicle equipped with said device. The temperature is measured using a calibrated measuring line (3) through which a measurement current flows and which comprises a plurality of taps (6a to 6h) for measuring potential. The measurement line (3) can be arranged either in or on the line or the line bundle and evaluation can be carried out in such a manner that the heat build-up of the measurement line (3) does not result in errors of measurement.
Abstract:
Die Erfindung bezieht sich auf ein Verfahren, eine Vorrichtung und ein Mittel zur Verhinderung eines unzulässigen Temperaturanstieges einer überwiegend aus Ammoniumnitrat bestehenden Füllung eines Lagersilos. Der Erfindung liegt deshalb die Aufgabe zugrunde, zu erreichen, dass beim Überschreiten eines vorgegebenen Temperaturlimits im Lagersilo die Temperatur im Silo schnell unter Zuführung eines geeigneten Mittels abgesenkt wird. Gemäß des erfindungsgemäßen Gedankens erfolgt die Lösung der Aufgabe mittels eines Verfahrens zur Verhinderung eines unzulässigen Temperaturanstieges einer überwiegend aus Ammoniumnitrat bestehenden Füllung eines Lagersilos, das dadurch gekennzeichnet ist, dass im Silo zur Ermittlung der Temperaturverteilung die Temperatur kontinuierlich überwacht und beim Überschreiten eines Temperaturgrenzwertes in der Füllung des Silos die Zugabe eines flüssigen Mittels zur Temperaturerniedrigung in oder auf die Füllung des Silos ausgelöst wird.
Abstract:
A food warmer having closed loop heating control (24) has a temperature sensor (14) in a warming zone (13) of the food warmer. The temperature sensor (14) has a rate of heat absorption and a rate of heat loss substantially the same as a food product (12) contained in the warming zone. First (16) and second (20) heat sources provide heat to the warming zone. The heat required to maintain the warming zone at a desired temperature requires heat from both the first and second heat sources. The first heat source (16) is operated continuously while the second heat source (20) is activated and deactivated in closed loop fashion based on input from the temperature sensor (14) to maintain a desired set point temperature of the warming zone.
