Abstract: 408,062. Thermionic cathodes. BENJAMIN, M., and ROOKSBY, H. P., c/o General Electric Co., Wembley, Middlesex. Dec. 6, 1932, Nos. 34544 /32 and 7367/33. [Class 39 (i).] An oxide coating for cathodes of the type in which a supporting body is coated with alkaline earth oxide or other compounds readily convertible into the oxide, or in which a selfsupporting mass of such material is formed comprises an inner layer relatively rich in barium and an outer layer relatively poor in barium. Preferably a substantially pure barium compound is deposited on a substantially pure strontium or calcium compound. If barium is present in the outer layer, the layer should consist of a solid solution, and not a polyphase mixture, of its ingredients. The proportion of barium present should be greater than that corresponding to two molecules of barium oxide to three of strontium oxide. A core may be dipped or sprayed with barium carbonate, dried, and dipped or sprayed with strontium or calcium carbonate, the latter layer being twice the thickness of the former layer. The usual heat treatment converts the carbonates to oxides. If the outer layer consists of a solid solution of strontium and barium compounds, this may be produced by precipitating the carbonates from the nitrates by ammonium carbonates.

A crystal oscillator of the type described in Specification 1,101,178 includes a driving transistor, a crystal 3, resistors 2, 6, 7 and capacitors 4, 5, 9, 10 and derives its supply from tap 17 on a voltage divider which is connected to a supply terminal 11 and which is constituted by a resistor 16 and a transistor 14. Oscillations from the collector of the driving transistor are applied over an amplifier 12 and a diode 13, poled as shown, to the base of transistor 14, there also being provided an oppositely poled diode 15 connected between amplifier 12 and the emitter of transistor 14. The transistor 14 is thus controlled to act as a variable impedance in the voltage divider 16, 14, so that the voltage at point 17, which is the supply voltage for the oscillator, falls if the oscillation level increases and vice-versa. With this arrangement the control voltage is not applied to the base of the driving transitor so that variation in the emitterbase capacitance, producing undesired frequency changes, does not occur.
