Title: Improvements in and relating to modulation systems for high frequency oscillations
IPC: H03C7/02
Filed: 1938-12-02
Abstract: 515,824. Modulating systems ; impedance networks. INTERCONTINENTAL SERVICE CORPORATION. Dec. 2, 1938, No. 35123. Convention date, Dec. 2, 1937. [Classes 40 (iii) and 40 (v)] A radio-frequency source is modulated by short-circuiting the transmission line connecting it to the load, at an intermediate point so chosen that the source is not loaded when the line is short-circuited. The radio-frequency source 1 is connected to the load 3 by a transmission line 2 which is short-circuited by a rotary capacitor 4 connected by a line 5 to a point B which is any odd number of quarter wavelengths from the source. Line 5 is any even or odd number, including zero, of quarter wavelengths long, and when the effective capacity shunted across point B is a minimum there will be no effect on the transferrence of power from source to load. When the shunting capacity is a maximum, the line is effectively shortcircuited, and due to the impedance-inverting property of the section AB no-power is delivered by the source. In order to avoid the necessity for exact dimensioning of the transmission lines, an additional loading in the form of a shortcircuited line 6 may be connected at point B. The electrical length of the short-circuited line is made such that the total length of lines 5 and 6, including the loading effect of capacity 4, is such that the impedance of line 2 at point B varies from zero to infinity. The system is adaptable to a radio beacon of the equi-signal type in which overlapping directional fields are radiated, Fig. 3 (not shown).

Title: Producing from impure water steam for driving a turbine and recovering part of the steam as pure water
IPC: C02F1/04
Filed: 1962-09-21
Abstract: 948,721. Distilling water. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 21, 1962 [Nov. 24, 1961], No. 36047/62. Heading B1B. [Also in Division F4] In a method of evaporating salt or other impure water to provide steam for driving a turbine at least part of which is subsequently recovered in the form of pure water the salt water is sprayed through a nozzle 12 into an evaporating chamber 11 into which superheated steam is also introduced through a nozzle 15 in sufficient quantity to flash-evaporate the salt water spray. The resultant lower-temperature steam passes from the chamber 11 through a moisture and salt separator 19 to a blower 20 and passes therefrom at increased pressure through a reheating section 24 of a boiler 23. Part of the thus superheated steam flows through a line 34 to a turbine 28 driving an electric generator 29 and the remainder is recirculated through lines 26, 17 to the evaporating chamber 11. The exhaust steam from the turbine 28 is condensed in condenser 30 and the condensate, i.e. pure water, is recovered by a pump 32. At start-up superheated steam from a source not shown is introduced into the chamber 11 by valve 18 and line 16. Dry salt collects in the conical base of the chamber 11 and is discharged therefrom. In a modification, Fig. 2 (not shown), the total amount of steam from the evaporating chamber flows through the reheat section of the boiler and then directly to the turbines ; in this arrangement the superheated steam passing to the chamber 11 is produced from a part of the condensate which is fed to the boiler and re-evaporated and superheated therein. In a further modification, Fig. 3 (not shown), a series of chambers are connected in cascade, the steam generated in one chamber flowing after reheating to the next chamber and so on. In this arrangement progressively increasing quantities of steam are generated and salt water evaporated in each succeeding evaporating chamber. The amount of pure water recoverable from the system therefore considerably exceeds the amount required for recirculation for steam for the first evaporating chamber.
