Abstract: 683,902. Valve circuits. DUMONT LABORATORIES, A. B. Jan. 12, 1950 [Jan. 29, 1949], No. 837/50. Class 40 (vi). A sine-wave generator comprises a triggered flip-flop in the anode circuit of one valve of which is a circuit tuned to the repetition frequency or to a harmonic of the repetition frequency of the triggering pulses so that an output sinusoidal voltage is obtained the frequency of which is equal to, or a multiple of, the triggering pulse repetition frequency. The Figure shows a cathode coupled flip-flop in which the circuit is changed from its stable to unstable state by the triggering pulses applied from source 10 and in which the circuit reverts to its initial state after a period determined by capacitor 17 and resistor 18. The circuit 25, 26 is tuned to the repetition frequency of the pulse train from source 10 and is shockexcited by the positive-going pulse at the anode of valve 23 to produce a sinusoidal output at that frequency. The resistor 18 is adjusted so that the flip-flop operates symmetrically with the durations of each of its two states of operation equal. When the generator is required to produce a sine-wave output the frequency of which is, for example, the second harmonic of the pulse repetition frequency of source 10, the circuit 25, 26 is tuned to the required output frequency and the duty cycle of the flip-flop is adjusted by means of resistor 18 so that the pulse train at the anode of valve 23 has a positive-going portion which has a duration of not more than one-fourth of the total pulse period.

Title: Improvements in or relating to the manufacture of titanium powder and massive bodies of titanium
IPC: C22B34/12
Filed: 1953-01-13
Abstract: Substantially pure titanium, in a form which is incapable of being crushed to fine powder, is treated with hydrogen, which is free from oxygen and nitrogen, in such a manner that the titanium absorbs sufficient hydrogen to render it brittle, the hydrogenated titanium being then crushed to powder and then heated in the loose or compacted state in vacuum or an inert atmosphere to remove the hydrogen.  The titanium, which may be in a porous form, is preferably subjected, prior to treatment with hydrogen, to a preliminary treatment to remove impurities and to activate its surface, e.g. by heating in vacuum at about 700 DEG  C.  The metal may then be heated in hydrogen at a temperature between 400 DEG  C. and 700 DEG  C. till saturated with hydrogen, then cooled in hydrogen so that the product contains 2-4 per cent by weight of hydrogen. The hydrogenated titanium after crushing and, if desired, mixing with alloying constituents may be compacted and heated to expel hydrogen and then further heated to cause the metal to sinter.
