Abstract:
A rigid polymeric matt-finish box, of rectangular shape and size generally resembling a package of chilled foodstuff, contains internally a block of iron (15) wrapped in elastomeric foam portions (16), as a heat-sink responsive to temperature of the surrounding air, and arising from incident radiation, in generally the same manner as a typically cook-chill foodstuff i.e. cooked chicken portions. Temperature sensor (17) is read at intervals controlled by time-interval sampling means (18) and these temperature data are stored electronically at (19). Computational unit (20) operates jointly, on temperature sampled and on a measured period of sampling, to indicate alarm conditions externally at (12), the other external light (13) being responsive to low-battery conditions at battery B. Interrogatable output means (22) are located behind glazed window (14) so that selectively an external interrogation unit, itself also with a glazed window, can be hand-held with the respective windows adjacent to actuate by a beam of I.R. light the interrogatable output means (22) and to transfer stored data at (19) out through window (14) to the external interrogation unit, for onward transfer or printout.

Abstract:
Embodiments relate to a method and apparatus for investigating the uniformity of concrete and/or grout. Embodiments can identify the existence of one or more anomalies in the uniformity of concrete and/or grout, and/or determine or estimate the size, shape, type, and/or location of one or more anomalies in the uniformity of concrete and/or grout. Embodiments can utilize a string of temperature measuring sensors placed within one or more access bore(s), such as tube(s), positioned at least partially within the concrete and/or positioned proximate the concrete. The measurements obtained from the temperature measuring sensors can then be used to assist in the identification of existence of, size of, type of, shape of, and/or location of anomalies in the concrete and/or grout.

Abstract:
A temperature measuring device for molten metal includes a porous plug with a first end and an opposed second end, an outer protective sheath with a closed end, an inner protective tube with a closed end, and a thermocouple arranged within an interior of the inner protective tube. The outer protective sheath extends away from the first end of the plug and the inner protective tube is arranged within an interior of the outer protective sheath. The porous plug comprises a substantially refractory material and the outer protective sheath consists essentially of substantially refractory metal oxide and graphite. A junction of the thermocouple is proximate to the closed end of the inner protective tube.
Abstract:
A target, such as a stack of frozen meat cartons (8), is irradiated with at least two transmitted electromagnetic radiation signals (3) of differing frequencies. The attenuation of the received signals (4) is calculated via a signal processing means (5). A first signal may have a frequency in the microwave or UHF spectrum, and a second signal may have a frequency in the radio frequency spectrum. Absorption of the first signal by water should be higher than the absorption by ice, and absorption of the second signal by ice should be higher than the absorption by water. Quantities such as the temperature and the fat content of the target can be determined from the calculated attenuations, for relatively thick targets and at sub-freezing temperatures.
Abstract:
The invention relates to a device for protecting and sealing sensors, especially with respect to liquid, moist and muddy environments. Said device protects the sensors and ensures that the connectors thereof remain completely watertight in all environments, including liquid and moist environments. Said device consists of two machined pieces which are fastened together. The first piece is shaped like the finger of a glove and tapered to form a point. The interior of the piece is recessed, forming a chamber which houses the sensor. The cylindrical part of the first piece is perforated with several holes, bringing the sensor chamber into contact with the outside environment. The part of the machined piece opposite the point is tapped and threaded. The tapping enables the sensor to be inserted. The thread fastens said first piece to a second machined piece which allows the sensor wire and connector to pass through. The device is completely sealed and can be inserted into the end of a stick or directly into the end of the wire. According to the invention, the device is particularly useful for protecting gas, pH and other sensors which are used in difficult environments, including moist, liquid and muddy environments, and said device is especially useful for treating waste products and composting.
