Title: Improvements in or relating to audio frequency thermionic amplifiers
IPC: H04B3/04
Filed: 1928-02-16
Abstract: 311,466. Smith, W. S., and McLachlan, N. W., Feb. 16, 1928. Thermionic amplifiers.-In order to prevent speech distortion, the output circuits of a threeelectrode valve amplifier comprise one or more resonant transformers or equivalent inductances designed as set out in Specification 304,710, so that the frequency-amplification characteristic of the amplifier as a whole is a rising curve substantially opposite to the falling frequency attenuation curve of the cable or line feeding the amplifier. Triode photo-electric cells may be used as an alternative to the thermionic amplifiers. As shown in Fig. 2 the secondary 6 of the coupling-transformer is shunted by a condenser 9 and variable resistance 8 serving to adjust the frequency-amplification characteristic to the desired value. A tertiary winding 7 and balancing condenser 14 prevent interelectrode capacity coupling. A resistance 16 in series with the primary winding 4 serves to adjust damping where the impedance of the valve 1 is not of the most suitable value. Resistances 10 in series with the grids of the following valves, and a shunt condenser 17, reduce any tendency to selfoscillation; or other suitable means for neutralizing interelectrode capacity may be used. The transformer coupling may be replaced by one or more resonant chokes tuned to different frequencies. The valves and transformers are housed inside separate earthed screening-boxes. As indicated in Fig. 5, the output from an amplifying- stage S may be split into several channels A, B, C each of which comprises a " shaping " amplifier of different characteristic, the output being subsequently combined in a common circuit K. Specification 290,351 also is referred to.

Abstract: 1,059,306. Valves. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Feb. 5, 1965 [Feb. 6, 1964], No. 5098/65. Heading F2V. Upon turning a control knob 23, Fig. 1, to any position between " OFF " and " PILOT," the knob may then be depressed to unseat a closure member 44, Fig. 2, and allow gas from an inlet to pass to a pilot-burner outlet 96, Fig. 1; a thermocouple current generated by the pilot burner energizes an electromagnet 46, Fig. 2, to hold the closure member 44 in the open position. Gas flowing past the closure member 44 is controlled by a disc valve 61 also operated by the knob 32 and having one segmental port 61B used when the knob 32 is in the " ON " position and three pilot segmental ports so that gas flows to the pilot burner in all positions of the knob except " OFF." Between the valve 61 and pilot burner is a filter and a throttle (82, Fig. 19, not shown). A pilot-burner gas-supply bypassing the filter and throttle may be provided. With the knob 32 in the " ON " position gas flows from port 61B and divides past the twin closures 120, 122 of a pressure-regulating valve and enters chambers 130, 132 which are interconnected and defined by diaphragms 15, 21, the former carrying a closure member 15A, which, when open, leads to the main-burner outlet 119. The closures 120, 122 are loaded by a light spring 139 and actuated by the gas pressure on diaphragm 21 which is loaded in opposition thereto by an adjustable coil-spring acting through a lever 150. Locking means are provided to prevent inadvertent movement of the knob from the " PILOT " to the " OFF " position. The closure member 15A is closed by a spring 180 and equalization of the gas pressure on both sides of the diaphragm 15; when the winding 192 of a U-shaped core 186 is energized, an armature (188, Fig. 9, not shown), is pivoted to close one port insert 196 and open another port insert 197 to vent the chamber 201 above the diaphragm 15 to the main burner or atmosphere so allowing the gas pressure therebeneath to unseat the closure member 15A. A chamber 221 communicating with the outlet 119 may lead to a pilot burner. The gaskets 14, 20 between the three die-cast casing-parts 10. 11, 12 are apertured to provide the interconnecting gas passages without requiring any machining of parts 10, 11, 12. The top of casing part 10 carries terminals 26-29 for the electrically-actuated valves and an earthing terminal 37, as well as the knob 32, and screws 34. 35 giving access to the regulator-valve spring and the pilot-flow throttle.

In a method of making a cathode, particularly for use in magnetrons requiring high current densities and a reverse of emissive material, a powdered mixture containing 5-15% by weight of alkali earth metal compounds which is decomposable to the corresponding oxides and at least 25% by weight of Mo and/or W is added to a lubricant solution such as a solution of stearic acid in ether, mixed until most of the ether has evaporated, then thoroughly mixed in a ball mill. Grain sizes of ten micron or less are specified. The mixture is then compressed at a pressure of several tons per square inch in a mould to form, for example, an annular emissive mass round a tubular molybdenum support. The cathode mass and support are next heated in a reducing atmosphere such as hydrogen or methane at a temperature of between 700‹C. and 750‹C. (for at least 15 minutes) thus forming the alkali earth oxides and possibly the basic molybdate and/or tungstate. The support may be retained or replaced after cooling before finally firing in an inert atmosphere for at least 15 minutes at 1300‹C. or higher. A modified method comprises compressing a mixture containing 5-20% of alkali earth metal boric molybdate and/or tungstate and at least 25% Mo +/or W and firing in an inert atmosphere as above. Cathodes made as above are said to have the same thermal expansion as the molybdenum support. The alkali earth compound may be the carbonate, nitrate or formate or mixtures thereof and may comprise more than one of the metallic radicals Ba, Ca, Sr. The powdered mixture may also contain a small amount of an activator such as zirconium hydride, silicon, titanium, hafnium or carbon. The cathode may be finally activated by heating to about 1100‹C. after assembly in a magnetron.
