[Class 39 (i).] A photo-electric cell has a cathode consisting of at least one of the metals of the cerium group of rare earth metals, photo-sensitive only to radiation of wavelengths below about 4500 A<c>, and an envelope made at least in part of such material or thickness as to be permeable to radiation of wavelengths below about 4500 A‹. The cathode is preferably of misch metal deposited on a layer 11 of a noble metal, such as gold, on the envelope in contact with a leading-in wire 18. The anode consists of two parallel uprights 13 and a cross member 15. A movable hollow member 19, carrying a strip of misch metal 20 secured by a strap 21, is arranged on the anode in the position shown, and is heated by induced current from a high-frequency coil to vaporize the misch metal, which is deposited on the layer of gold. The member 19 is then moved away to the position shown by dotted lines. The layer of gold is applied by painting with liquid bright gold, drying for a few minutes at 150‹ C., and baking for 10-15 minutes at 500‹ C., a stream of air being passed through the envelope to remove volatilized material. In order to render the envelope transparent in the desired region, for example 2900 A‹, a window 22 is formed by heating to form a re-entrant bulbous part with a thin dome. In a modification the member 19 is of cylindrical shape with a concave part along its length for directing the volatilized metal on to the envelope.

Abstract: 592,835. Valve circuits for radio reception. JOHNSON,E.A. June 2, 1945, No. 13929. [Class 40 (v)] [Also in Group XXXVIII] In a modulating circuit, a capacitor is changed to a potential proportional to the instantaneous amplitude of the voltage to be demodulated through an electronic switch periodically closed by a reference oscillation Fig. 1 shows an arrangement in which the reference and the modulated potentials (V and v respectively) appear across the secondaries of transformers 2 and 1. Leaky grid valve 4 and hence valve 3 conducts on positive peaks of V so that capacitor 7 is charged or discharged to a potential proportional to the instantaneous sum of V and v, once per reference cycle. In the arrangement of Fig. 3, v and V are applied to transformers 11 and 10. The effect of v is to alter the otherwise equal potentials to which capacitors 14 and 15 are charged on alternate peaks of V, so that a voltage appears at the junction 19 of resistors 17 and 18 with respect to earth, which is adjusted once per cycle of V to the instantaneous value and sign of v when V has its peak. The time constant C16 (R17+R18) is made long compared with the periodicity of V to maintain the output constant between switching periods. To prevent paralysis of the circuit if v exceeds V a relay may be connected across transformer 11 to place a discharge resistor across C 16 if v exceeds a predetermined valve, alternatively C16 may be omitted and the time constant 2C14.C15 (R17+R18)/C14+C15 made of the order of one period of V. A full wave version of Fig. 3 (Fig. 4, not shown) is also given.' The output voltage being adjusted every half cycle of V. A biassed output may be obtained in either case by making R17 and R18 unequal.
