IPC: H03B5/12
Filed: 1957-05-09
Abstract: 880,377. Transistor oscillator circuits. POSTMASTER-GENERAL. May 1, 1958 [May 9, 1957], No. 14832/57. Class 40(6). An oscillator circuit comprises a transistor T, two series tuned circuits L1C1, L2C2 connected respectively between the emitter and base electrodes and between the collector and base electrodes of the transistor and a feedback path comprising an impedance interconnecting the two tuned circuits. In the circuit shown the power supply is connected across a potential divider chain R2R3, the output of the oscillator is supplied to a load through an output transformer T1 and the feedback impedance is constituted by a high-valued resistance RF. The circuit may be modified by making the feedback impedance complex, by making the capacitor C4 connected across the primary winding of transformer T1 variable or by taking the output from a secondary winding coupled to the inductor L2, in which case it is preferable to reverse the positions of the components in the tuned circuits, so' that inductor L1 is connected to the emitter electrode and capacitor C2 is connected to the collector electrode. The feedback connection may be made between tapping points on the inductors or capacitors.

Title: A process of producing humous colloids
IPC: B01J13/00
Filed: 1929-05-16
Abstract: 312,233. Eberhard, R. May 22, 1928, [Convention date]. Colloidal compounds.-Colloids are obtained by extracting humous substances, e.g. peat, with neutral or weakly alkaline water-soluble organic compounds containing nitrogen. Suitable compounds are hexamethylene tetramine, urea, formanilide, formaldoxim, acetaldehyde-ammonia, piperazine. The products are in some cases crystalline bodies which dissolve in water to produce colloidal solutions. Combined humous colloids may be obtained by coupling the products with inorganic or organic substances which are soluble in water or in aqueous solutions of the extracting agents. Such substances are pyrocatechine, hydroquinone, resorcin, pyrogallol, yeast, glue, tannin; also silver nitrate, arsenic acid, mercury chloride, sodium citrate, additionproducts or substitution-products of ureas. &c. Substances soluble in melts of the extracting agents may be similarly used, e.g. chlorophyll, aniline, iodine, silicic acid, calcium fluoride, aluminium hydroxide, mercury sulphide. To obtain sulphur-containing colloids, extracting agents containing sulphur as well as nitrogen may be used, or inorganic sulphur compounds such as ammonium sulphide or sodium thiosulphate may be added to the extracting agents. Acid colloidal solutions may be obtained by acidifying the solutions obtained with extracting agents not containing sulphur.
