Title: Improvements in coupling devices for high-frequency electric circuits
IPC: H03H7/01
Filed: 1938-05-16
Abstract: 515,194. Wireless receiving sets; impedance networks; transformers. JOHNSON LABORATORIES, INC. May 16, 1938, No. 14572. Convention date, June 3, 1937. [Classes 40 (iii) and 40 (v)] [Also in Group XXXV] The coupling between a pair of tuned circuits, in an intermediate-frequency amplifier for instance, is varied simultaneously with the tuning of the circuits, so as to keep the selectivity or band-width constant when the tuning is being adjusted, by the use of a pair of magnetic cores 6 whose position can be set by means of screws 11. As the cores 6 within the insulating tube 7 are moved away from one another into the coils 4, the self-inductance of the coils increases while their mutual inductance decreases. At the same time their ratio Q of reactance to resistance increases and the effect on selectivity of this increase is compensated by the effect of the decrease of the mutual inductance. The condensers 5 are mounted on the insulating base 9 of the assembly, within a shield can 3. The coupling is slightly above the critical coupling. Specifications 468,675 and 515,305, are referred to.

Abstract: 553,315. Treatment of ferruginous materials for recovery of iron and other mineral constituents. ABBEY, A. (Titan Co., Inc.). Nov. 12, 1941, No. 14587. [Class I (iii)] Ferruginous material containing also the valuable mineral constituents is treated by calcining the finely divided material under reducing conditions to reduce the major portion of the iron to metallic form, oxidising this to iron oxides and separating the oxides from the other metallic constituents. The other mineral constituents may be manganese, copper, chromium, aluminium, vanadium, titanium and columbium, the calcining may be at a temperature between 800‹ C. or 1,000‹ C. and may convert 50 to 95 per cent. of the iron to the metallic state. The oxidation may be effected by wetting the mass with water and treating with an oxidising gas at a temperature between 40 and 200‹ C. The separation of the iron oxide may be by washing the iron oxide off with water. Pigments and other synthetic products may be prepared using the iron oxide and other residual products thus obtained. Coal, coke, charcoal, carbon monoxide, hydrogen, &c. may be used in reducing in a rotary kiln or stationary retort. In the oxidation air and steam may be present and electrolytes such as NaCl, NH 4 Cl, MgCl 2 , CuCl 2 , HCl, and FcCl 3  may be used as accelerators. The separation of oxide may be electromagnetic, or by wet flotation, electro-flotation or air separation such as by elutriation. Specification 547,898 is referred to.
