Title: Improvements in or relating to the thermal generation of electric current
IPC: H01L35/16
Filed: 1937-08-24
Abstract: 501,410. Thermo-electric generators; heat-sensitive cells; alloys. MILNES, H. R., and MILNES RADIO CO., Ltd. Aug. 24, 1937, No. 23244. [Class 53] [Also in Groups II and XL] An alloy for the thermal generation of electric current comprises copper and silver saturated with selenium. The copper and silver are alloyed in the desired proportions by melting and allowed to cool to a dull red. The selenium is then sprinkled on the alloy and absorbed. The alloy is melted and cooled to dull red several times, selenium being added each time until no more is absorbed. Any surplus selenium is evaporated by maintaining a dull red heat for a short time. Such an alloy, if heated on one side and cooled on the other produces an electric current in a direction dependent on the composition of the alloy. In a "positive" element copper should exceed silver by at least three times and in a " negative " element silver should exceed copper by at least one and a half times. A protective coating of rhodium, platinum. palladium or iridium may be put over the element. The thickness between hot and cold sides should preferably not exceed an eighth of an inch and in use heat may be applied through a metal or alloy such as nickel, cobalt, iron or lead, while the opposite side may be kept cool by contact with a good conductor such as copper. Preferred proportions for a " positive " element are 75 to 90 per cent by bulk copper, 25 to 10 per cent by bulk silver and selenium to saturation and for a " negative " element 75 to 60 per cent silver, 25 to 40 per cent copper and selenium to saturation. Tellurium, sulphur or oxygen may be added to the alloy in order to produce a desired melting point or hardness.

Abstract: 797,636. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. July 27, 1956, No. 23303/56. Class 39(1). [Also in Group XL(c)] The invention relates to an arrangement for stabilizing the anode current of a screen-grid type valve 1 against changes in heater supply voltage, in which there is provided an auxiliary valve 4 having a load resistor 6, from which the screen-grid potential of the valve 1 is derived. The valves are provided with cathode bias resistors 2, 5 respectively and the grid of the valve 4 is earthed, while a variable resistor 9 is provided in its heater circuit. The circuit is so adjusted, by means of resistors 5, 9 that any increase in anode current in the valve 1 due to an increase in heater voltage is compensated by a decrease in screen-grid voltage, which is brought about by the corresponding drop in anode potential of the valve 4. According to the invention resistors 5, 9 are omitted, the valves being enclosed in the same envelope and designed to provide the necessary compensation without them. The two sets of elements may have separate cathodes or share a common cathode, and the compensating section may comprise a diode.
