Filed: 1943-05-20
Abstract: 578,088. Valve generators; coilless resonators. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. May 20, 1943, No. 014. [Classes 40 (iii) and 40 (v)] Unwanted modes of oscillation in an ultrahigh-frequency generator are prevented by associating with the oscillating system a member which is not effectively coupled to the system when the latter is oscillating in the wanted mode, but is coupled at other times and modifies the frequency of the unwanted oscillations, to prevent their being sustained or to render them innocuous, or damps them out. In the known push-pull oscillator shown, a rod 13 is arranged at equal distances from the quarter-wave rods 6, 6<1>. In the desired mode, oscillation in these rods are in opposite phase and the rod 13 is without effect, but for the mode in which oscillations are in phase, the rod 13 is effectively coupled. Dissipative elements may be associated with the member 13. In a modification, the rod is replaced by a loop which is tuned by a bridge 15.

Abstract: 512,907. Recovering sulphuric acid. TITLESTAD, N., ALLEN, L. N., and CHEMICAL. CONSTRUCTION CORPORATION. March 18, 1938, No. 8477. [Class 1(ii)] Denitrated spent sulphuric acid is decolorized by blowing superheated steam, either alone or in admixture with other hot gases, into a hot body of the acid which has been previously concentrated to about 90-96 per cent. strength. Spent denitrated acid of about 65 per cent., strength is continuously admitted at 20 into a concentrating chamber 22 in which it is concentrated to 80-85 per cent. by means of hot air admitted through a pipe 12 and valve 13. Acid continuously overflows from this chamber to a chamber 23 in which it is concentrated to 94-96 per cent. by hot gases entering through a valve 14. The acid then passes to a decolorizing chamber 18 where it is subjected to superheated steam generated in a coil 6 and supplied through a pipe 7. The acid is decolorized and its concentration lowered to 92-93 per cent. by a condensation from the steam. Finally, the acid is aerated in a vessel 19 by means of air supplied through a valve 10 which concentrates. it to 93-94 per cent., and is removed to a vessel 15. Alternatively, hot air may be used for the final treatment to obtain an acid of higher concentration. The hot combustion gases are supplied from a furnace 4 which also heats thecoil 6.
