Patent GB-1376066-A (GB)
Title: Thermal stabilization arrangement
IPC: H01J49/02
Filed: 1972-02-17
Abstract: 1376066 Automatic control of temperature VARIAN MAT GmbH 17 Feb 1972 [20 Feb 1971] 7457/72 Heading G3R In a temperature stabilizing arrangement an NTC resistor R 1  comprising parts R 1a ,R 1b  sandwiching an object RH (e.g. a field plate probe of a mass spectrometer) and connected in a bridge B r , functions both as a heater and as a temperature sensor in the control of the temperature of said objects. Any bridge unbalance voltage S o  due to temperature deviation in a magnet air-gap S p  of the spectrometer, operates through an amplifier to adjust the bridge energizing voltage U therby changing the current through R 1  and hence also the temperature sensed and the resistance of R 1  until balance is restored. The temperature of R 1  and the probe RH is thus maintained substantially constant. By sandwiching the probe R H  between two platelike parts R 1a , R 1b , the probe lies in a zone of R 1  in which temperature change is minimum. A signal SH from field probe R H  is used in a known manner to indicate mass number which is dependent upon field strength H. The resistance R 1b  may be a thermistor bead which R 1a  is in the form of a plate, as illustrated in Fig. 2 (not shown).

Abstract: 1,093,337. Automatic temperature control. McGRAW-EDISON CO. Feb. 21, 1966 [Oct. 5, 1965], No. 7517/66. Heading G3R. Apparatus for curing resin impregnated fabrics comprises one or more air pervious bags 5 over which is dressed the fabric to be cured and into which is directed a stream of hot air which is maintained at a constant temperature suitable for curing the fabric. An air blower 7 forces air into pre-heating exchangers 10, 13 in the first of which the air is heated by a steam coil 12 and in the second of which it is heated by a finned electric heater 14, the pre-heating stages  being uncontrolled. Thereafter the air passes into a housing 16 where it passes over a controlled electric heater 18 and thence by way of a pipe 19 and control valve 20 into the bag 5. A thermistor 28 senses the temperature of the air after it has passed over the heater 18 and is effective by way of a D. C. amplifier and relays to control the energization of the heater 18. The thermistor 28 forms one arm of a bridge which bridge also comprises a variable resistor for setting the desired curing temperature. The valve 20 contains a by-pass arrangement 46 so as to by-pass or re-circulate the heated air when no curing is in process.
