Abstract: I disclose method and means for mounting and cooling a heatproducing electrical device and arranged such that a considerable quantity of heat can be conducted across an electrically isolating coating, although the unit heat transfer coefficient of the coating is relatively low. This is accomplished with mounting members associated with the device and having a relatively large area of the coating sandwiched therebetween. The dielectric strength is therefore improved, while the total heat transfer coefficient is improved to the extent that considerable heat can be transmitted from one mounting member to the other without large temperature differentials. Also disclosed are novel methods for coating and disposing the mounting members in optimum heat transfer arrangement. One of the mounting members, which may be in the form of a chassis or base structure, is provided with sufficient area that heat is convected and/or radiated therefrom without the use of bulky cooling fins or other convecting structures.

Abstract: I disclose, in an optical pyrometer system, the combination comprising an optical system for receiving and focusing incident radiation from an object, a beam splitter disposed in a light path of said optical system, for passing a portion of said incident radiation to a direct viewing aperture of said optical system and the remainder of said incident radiation to a second aperture of said optical system, light sensitive detecting means juxtaposed to said second aperture for receiving incident radiation passing therethrough, and said direct viewing aperture and said second aperture being sized so that the light sensitive area of said detecting means is completely covered by said second aperture radiation when an object image focused by said optical system completely fills said direct viewing aperture.
