摘要:
A sensor arrangement for measuring the temperature of molten masses uses a receptacle having at least one strip-shaped or wire-shaped carrier and an opening on its upper side, with a thermoelement placed inside the receptacle. In order to make available a sensor arrangement for the exact determination of the liquidus temperature of molten cryolite, the receptacle is made of metal. A temperature measuring device with a sensor arrangement of this type, has at least one carrier mounted at its end facing away from the receptacle in a sleeve, the sleeve being detachably connected to a mounting device. In addition, a process for measuring the liquidus temperature of molten cryolite in a receptacle vibrates the receptacle during the cooling of the molten cryolite.

A method and apparatus for measuring the core body temperature of infants or persons without volitional bladder control utilizing minimal urine volume. The device employs a readily deployed collection surface contiguous with a sump or reservoir into which the collected urine contacts a superabsorbent powder. Affixed to the reservoir is a peak temperature sensor for indicating the maximum temperature of the urine and thereby the core body temperature of the donor.

A measuring probe for taking gas samples and/or making temperature measurements in furnace charges that are hot and/or have gas flowing through them, for example in blast furnaces, comprises a measuring head axially movable in a water-cooled sampling tube and having a thermocouple in a gas inlet opening, said head consisting at least in part of an alloy containing at least 90% molybdenum and characterized by a long service life.

The probe comprises a support in the form of a sheath, a series of internal pipes, retained by spacers and connecting orifices distributed along the sheath to a device for measuring and for receiving the gas samples outside the furnace, and thermocouples arranged at the level of the said orifices. In order to enable the pipes to be replaced without disassembly of the probe, the said orifices are situated in steps provided in the sheath, while the internal pipes, for taking gas samples and heat measurements are all individual, straight and exchangeable elements housed in straight support and protection channels, each traversing the sheath from the outside as far as the respective step.

A grain probe for sampling and measuring the physical characteristics of stored grain in situ. The probe has a telescopic shaft with a meter fixedly attached to one end thereof and a novel grain probe tip fixedly attached to the opposite end thereof, a grain receiving chamber within the tip, an environmental measuring element is affixed within the grain receiving chamber and is directly coupled to a readout meter; and there is provided a novel mechanism for automatically closing the grain receiving chamber to grain kernels while the probe tip is being inserted into stored grain and automatically opening the grain receiving chamber to grain kernels for sampling and direct contact with the environmental measuring element to provide instantaneous physical characteristic information as the probe tip is slightly withdrawn from the stored grain.
摘要:
An apparatus for providing a uniform thermal history of a free-falling glass gob having a hollow, heat-resistant conveyor tube extending between the point of shear of the molten glass and the desired mold to which the glass is to be directed and having an electrical heating means associated with at least a portion of the tube which may be controlled by a control means to transfer thermal energy through the tube to the glass gobs passing within the tube, the control means being fed information received from sensing means located at selected points along the tube which is activated by infrared rays transmitted through openings in the tubing by the glass gobs, which temperature information is transmitted to the control means and integrated to determine the operation of the heating means.
