Abstract
1,246,416. Television camera. CENTRAL ELECTRICITY GENERATING BOARD. 6 April, 1970 [18 April, 1969], No. 20010/69. Heading H4F. [Also in Division G2] A television camera for viewing the inside of a furnace &c., is protected from the intense infrared radiation up to 3Á by an air-cooled lens system comprising a quartz plate 21, an infrared filter 19 blocking infra-red above 0.8Á and glass lenses 13 and 11. Cooling air enters at 17, passes round the lens-tube 12 and over the faces of the filter and plate by means of holes in their mountings. The air also serves to blow out any dust and is partly diverted via holes 25, 26 to cool the camera. A blue filter 27 is optional.
