Abstract
Abstract A sensor is borne by a head extended by a metallic arm which passes through the flame of the burner. To avoid exaggerated heating effect on the capillary tube communicating the sensor to the thermostatic control, it is surrounded by a sheath of highly conductive metal. This sheath ends in a tube of the same metal which can be extended by a radiator. In this way, the conductive sheath constitutes a heat pump removing heat to the outside. The head can be protected on the inside by a layer of insulating material. The device is particularly useful for domestic gas cookers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
Thermostatic control device for use with a support table having heat generating means for heating vessels, said device comprising an arm arranged to traverse said heat generating means and be so exposed to a high heating effect, a temperature sensor resiliently borne at one end of said arm so that it can contact said vessel and the other end of the arm being pivotally connected to the support table, a thermostatic control fluidcontaining member connected at the other end of said arm, a capillary tube carried by said arm resiliently connecting said sensor to said thermostatic member and sealed with a fluid therein, and a sheath of highly heat-conductive metal within said arm surrounding said capillary tube and terminating at an external cold point in said support table remote from said sensor, so as to protect the capillary tube from excessive heat and conduct heat away from the sensor and capillary tube.
Claim 2
Dependent Claim
152 words

Claim 3
Dependent Claim
41 words
Device according to claim 1, said other end of the sensor arm being hinged around the cold point in said support table, as a flame cooker, wherein the arm is constructed of a metal resistant to the effect of the flame.
Claim 4
Dependent Claim
28 words
Device according to claim 1, including a conductive part ending said arm and arranged on said support table connected in articulated manner at the external table cold point.
Claim 5
Dependent Claim
29 words
Device according to claim 1, including a radiator member terminating, on the side of the table cold point of the assembly of the capillary tube and its conductive sheath.
Claim 6
Dependent Claim
39 words
Device according to claim 1, including a metallic head bearing the sensor proper and joined by said arm, and a sheath of insulating material inside of the head to protect it against the effect of the heat generating means.
Claim 7
Dependent Claim
16 words
Device according to claim 1, including a head of heat insulating material bearing the sensor proper.
Claim 8
Dependent Claim

Dependent Claim
11 words
Device according to claim 6, wherein the head material is enamelled.
Claim 10
Dependent Claim
22 words
Device according to claim 2, including a heat insulating material, interposed between the capillary tube and the external wall of the arm.
