Title: Improvements in light measuring devices

Filed: 1935-07-30
Abstract: 460,452. Electric signalling systems. TRUECOLOUR FILM, Ltd., DOLGORUKI, E. SANDERS-, and WHALEN, F. C. July 30, 1935, No. 21612. [Class 40 (i)] [Also in Group XL] A device for measuring light quanta for use as an exposure meter comprises a thermionic valve system adapted to operate a counter which records the number of impulses or surges in a circuit, the rate of production of the impulses being controlled by the intensity of light falling on a photoelectric cell. As shown, the photoelectric cell P, on which the light to be measured is incident, is connected in parallel with a condenser C between the grid and cathode of a thermionic valve T. The condenser is supplied with a momentary negative charge which leaks away through the cell P at a rate depending on the intensity of illumination of the cell. The negative potential on the grid consequently falls and the anode current rises, this current being passed through a relay R which, when the current reaches a given value, operates to apply a fresh negative charge to the condenser. A succession of impulses is thus produced in the anode circuit and these impulses are used to operate a counter. The counter may be operated by the relay R but preferably a second relay R2 is used which operates at a lower current than the relay R. The grid circuit is highly insulated to prevent leakage. The circuit operates direction alternating current which is fed to the primary of a transformer TR having three secondaries, one of which feeds the anode circuit of the valve T which acts as its own rectifier. Another secondary winding supplies the cathode heater of the valve, and the third winding supplies the negative charge for the condenser through a rectifier MR. The operation of the valve is rendered insensitive to mains voltage fluctuations by so choosing the value of the negative potential applied to the grid that the change in the said potential when the mains voltage changes is just sufficient to compensate for the variation in the anode current directly due to the said changes of mains voltage. Specification 435,820, [Group XX], is referred to.
