Abstract: 630,896. Heat dissipating photocell enclosure. COMBUSTION CONTROL CORPORATION. Jan. 22, 1947, No. 2004. Convention date, June 20, 1945. [Class 40 (iii)] In photo-electric supervisory apparatus, e.g. for a furnace, the photocell housing is constructed so that the photocell is spaced from the furnace wall and heat conducted from the furnace or absorbed from the radiation by the component infra-red filter is dissipated before reaching the photocell and associated apparatus. Fig. 3 shows a controlling photocell 17 located in a container 15 having a sight opening 18 through which the cell is exposed to the radiation from the furnace and to the wall of which is attached a pipe 49 screwed to a flange 22. Bolts 24 secure the container to the flange, and radiation plates 25, 26, 27, 28 are positioned therebetween by spacers 29 through which the bolts pass. Plate 25 has a central aperture 35, and similar apertures 31, in plates 26, 27, 28 have flanges 32, those of plates 26, 27 facing each other while that of plate 28 faces the beaded edge 33 of the container sight opening. Heat insulating dust excluding collars 34 (which may be omitted under humid conditions) surround the flanges. A shutter 36, Fig. 5, carrying in a recess a heat resistant transparent sight glass 44 is interposed between plates 25 and 26, and pivots outwardly about one of the upper spacers 29 to permit access for cleaning. A spring clip 40 engages one of the lower spacers 29 to retain the shutter in the operating position, in which it may be spaced off from plate 25 by the heads of rivets 45 leaving a space 46 through which air is drawn by the furnace draft to cool the glass and prevent the deposit of soot thereon. A similar oppositely pivoted shutter 47 carrying an infra-red filter 48 is interposed between plates 27, 28, no air-space being provided. Heat conducted from the furnace or absorbed by the infra-red filter is dissipated by the circulation of air around the radiation plates, and the flanges surrounding the central apertures exclude external light from the photocell. Fig. 11 (not shown) illustrates a modified flange construction. Additional plates may be interposed between the flange 22 and the container 15, while the shutters may be locked in position by captive screws. The invention is stated to be applicable to densitometers or smoke control apparatus.
