ABSTRACT:
An improved thermopile construction particularly adapted for use as an electric generator for producing a signalin response to heat from a pilot flame. Groups of elongated elements of dissimilar metals are assembled or arrayed in a circle within a metal sleeve to produce a pilot generator. The first group of elements is arrayed against the inside wall of the metal sleeve and the second group of elements is assembled radially inwardly from the first group. Respective ends of the elements of the first group and the second group are joined with the opposite end of the respective end of the element of the second group being joined to the opposite end of the next adjacent element of the first group. Individual elements of each group have a cross-sectional configuration to provide for optimum heat transfer between the sleeve and elements of the first group and to provide for assembly of the elements of the second group in a circle of smaller diameter. The assembly provides for hot thermocouple junctions at one end of the sleeve and cold junctions at the opposite end.
