A disposable maximum reading thermometer comprises a body (40) in which a capillary passage is defined, a reservoir (41) communicating with the passage and a heat expansible indicator medium (46) contained in the reservoir. The reservoir and the passage are adapted to allow expansion of the medium in the passage when the medium is subjected to heating. At least a part of the passage wall exposable to the indicator medium is adapted to undergo a detectable and irreversible change of its light penetration characteristics when brought into contact with the medium. The capillary passage is defined by a rod (48) arranged in a longitudinally extending bore (42) of the body (40). The surface of the rod is frosted (matt) or opalized, preferably by a mechanical treatment, and adapted to be deopalized when brought into contact with the medium. The medium is preferably a greasy substance having an index of refraction substantially identical to the index of refraction of the material of the body (40) and a melting point range of some degrees centigrade in the relevant temperature range.

Disposable maximum reading thermometer and a method for the production

Feeding bottle having an air intake valve

A process, such as for instance the operation of a machine, is automatically supervised by monitoring at least two of the operational parameters which are desired to have a prescribed relationship to each other. A curve is formed which graphically represents the actual monitored relationship of the parameters, and it is compared to a standard curve representing the desired relationship of the parameters. In the event of a deviation between the curves, a signal is produced to indicate such deviation. An apparatus for carrying out the method is also disclosed.
