Abstract
964,031. Automatic temperature control. C.A. HENN-COLLINS. March 7, 1962 [March 7, 1961], No. 8318/61. Drawings to Specification. Heading G3R. [Also in Divisions H1 and H3] In a temperature controlled crystal oven, the associated oscillator circuit is also mounted in the oven to minimize temperature effects. The crystal and oscillator circuit is enclosed in a vacuum flask in which is mounted a heater fed through a transistor controlled either in an on-off fashion by a contact thermometer or progressively by a thermistor connected in a D.C. or A.C. bridge circuit.
