专利汇可以提供Space thermostat with automatic solid state anticipator专利检索，专利查询，专利分析的服务。并且A space thermostat embodying an automatic solid state anticipator, the anticipator including a parallel diode circuit connected across a heater resistor with the diodes poled in opposite directions and effective to clip the peaks of an A.C. signal applied to the resistor thereby enabling the anticipator to function with diverse power sources having different output voltage and/or current values.，下面是Space thermostat with automatic solid state anticipator专利的具体信息内容。
1. In a thermostat, the combination including a thermostatic element, an anticipator operatively associated with said thermostatic element, said anticipator including an electrical resistance heater disposed adjacent said thermostatic element and effective, when energized, to heat said element, and a pair of oppositely poled rectifiers electrically connected in parallel with said heater and effective to clip the peaks of an A.C. signal applied thereto.
2. The combination as set forth in claim 1 including means for adjusting the physical position of said heater relative to said thermostatic element.
3. The combination as set forth in claim 1 wherein said rectifiers are silicon diodes.
4. The combination as set forth in claim 1 wherein said rectifiers are thermally isolated from said thermostatic element.
5. The combination as set forth in claim 1 wherein means is provided for thermally insulating said rectifiers from said thermostatic element.
6. In a furnace control system, the combination including furnace actuator means adapted to be connected to a source of A.C. current, thermostatic switching means, electrical heating means operatively associated with said switching means, and a pair of oppositely poled rectifiers having a predetermined voltage drop and electrically connected in parallel with said heating means, said rectifiers being effective to clip the peaks of an A.C. signal applied to said heating means.
7. The combination as set forth in claim 6 including means for adjusting the physical position of said heating means relative to said thermostatic switching means.
8. The combination as set forth in claim 6 wherein said rectifiers include a parallel silicon diode circuit.
9. The combination as set forth in claim 6 wherein said rectifiers are thermally isolated from said thermostatic switching means.
10. The combination as set forth in claim 6 including means for thermally insulating said rectifiers from said thermostatic switching means.
11. A space thermostat for controlling ambient temperature, said thermostat comprising, in combination, a thermally responsive member, a pair of contacts operated by said thermally responsive member from an open position to a closed position upon a decrease in the ambient temperature, an electrical heater mounted adjacent said thermally responsive member and adapted to locally heat said thermally responsive member, and a parallel rectifier circuit connected across said heater and having a pair of rectifiers poled in opposite directions and effective to clip the peaks of an A.C. signal applied to said heater upon closure of said contacts.
12. The combination as set forth in claim 11 including means for adjusting the physical position of said heater relative to said thermally responsive member.
13. The combination as set forth in claim 12 wherein said rectifiers are silicon diodes.
14. The combination as set forth in claim 13 including means thermally isolating said diodes from said thermally responsive member.
