Title: Improved method of pyrometry and pyrometers for carrying out the method
Inventor: GIBSON ALAN FRANK
IPC: G01J5/08
Filed: 1949-07-30
Abstract: 684,483. Radiation pyrometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 3, 1950 [July 30, 1949], No. 20073/49. Class 40 (iii). In a radiation pyrometer the quantity of radiation in two different frequency bands both having the same effective minimum is compared to give a measure of temperature. As shown, radiation from the source whose temperature is required is split by wedge mirrors 3 into two separate beams, each beam passing through a separate filter 15 or 16 to a rotating shutter 11. This shutter is silvered and so shaped as to reflect the beams alternately on to a lead sulphide cell 10.. The other beam passes to a ground glass screen 6 which may be used in focusing the instrument. The cell output is amplified and fed to a phase-sensitive rectifier 31 which may be as described in Specification 592,835 and which feeds an indicator 32 showing the sense of the inequality, and a further amplifier 33 to control a servomotor 34. This motor adjusts through gearing a shutter in the path of one of the beams to balance the two outputs, the adjustment of this shutter being calibrated to indicate temperature. In a further embodiment, Figs. 1, 2, 3 and 4 (not shown), the balance is obtained by manual adjustment of the shutter, which carries a pointer moving over a scale calibrated in temperature, and the chopper is not silvered but consists of a plate with a castellated edge which allows one beam to pass to a mirror while blocking the other. The beams are reflected forwardly from the mirror to a light-sensitive cell and the mirror must be removed to make use of the focusing screen. The filter disc carries on it three pairs of filters, any one pair of which may be brought into position, filters mentioned are of cellulose acetate and " Perspex " (Registered Trade Mark). The Specification mentions that by synchronizing the exposure of the pyrometer it is possible to measure the temperature of a moving part, e.g. a spot on the periphery of a rotating wheel.
