Abstract: Electronically timed and electrically operated lamps are utilized in place of traditional candles. Actuation of a switch, located on each lamp holder, illuminates that lamp for an accurately timed predetermined period. One clock is utilized to drive a plurality of independent timers, each associated with an individual lamp. The lamp units are provided with the capability of being plugged into the timing unit, so as to permit interchangability.

Abstract: An electronic thermometer probe assembly dseigned to provide an instrument which is highly accurate and convenient to use. The thermometer includes a probe section having a flexible plastic shaft with a thermistor mounted at its tip. A disposable probe sheath covers the thermistor and flexible shaft, and is replaced after each measurement to ensure that the instrument remains uncontaminated. The sheath is cylindrically shaped, and has an open end which extends onto a conically-shaped retainer for the sheath. The thermometer handle includes an axially displaceable section, movement of which dislodges the sheath from the retainer to enable it to be disposed of conveniently.
