Letter: Aspiration of thermometer fragment.

Lens Fragment Removal from the Anterior Chamber Using Cannula Aspiration

before concluding the surgical procedure, these complications can be prevented. We describe a case in which a lenticular fragment is identified and describe a novel technique of using a cannula to remove the piece rather than the typical re-insertion of the irrigation/aspiration handpiece which can actually create turbulent flow and lead to loss of the fragment under the iris or in the ciliary ...

An Imaging Radiation Thermometer

For many years radiation thermometers have been used to make non-contact temperature measurements of hot objects, particularly in industrial situations such as reformer furnaces, steel reheat furnaces, and ceramics kilns. They occupy an important niche in temperature measurement since any other type of thermometer would have very slim chances of surviving in these and other such hostile environ...

An improved tele-thermometer.

A thermistor leaf thermometer.

An instrument is described which allows measurements of leaf temperature within about 0.3 C. It consists of a special thermistor probe, a small circuit box, and a standard ammeter. The circuit box can easily be fixed to the meter and contains a battery, which passes 0.3 milliampere through the thermistor, and also contains an integrated circuit amplifier, so that the meter reads 20 C full scale...
