Title: Circuit setting microwave power fed to radiator - uses variable impedance in resistor sink for mismatching of branch conductor unit
Inventor: BOETTCHER LUTZ DIPL ING
IPC: A61N5/02
Filed: 1979-07-24
Abstract: The microwave radiator (21) is connected via a circulator (17) to a magnetron (13) which receives power via a stabilised transformer (10). If the equipment contained no more components the HF power generated would be radiated. The system, however, provides for a mismatchable conductor (19) terminated by a resistor (R). If the variable conductor length is set so that no energy is reflected, all the energy reaches the resistor to be absorbed in that conductor branch. None of the microwave energy is left for the radiator (21). By increasingly mismatching the branch conductor unit (19) an increasing portion of the magnetron power is reflected and that portion becomes available for being radiated in the radiator (21). A wave splitter (22) may pass a small portion of the power reaching the radiator, to an RF meter (27).

Title: Process for operating a heating boiler and apparatus for carrying out the process
Inventor: STECKERMEIER JOHANN
IPC: F23N5/20
Filed: 1981-02-18
Abstract: The invention relates to a process for operating a heating boiler, which can be heated by solid fuel and by oil or gas, and an apparatus for carrying out this process with an electric line leading to a burner as well as with a main switch. In order to regulate the ignition of the solid fuel with an oil or gas flame, the invention provides that, during a maximum time period of preferably 20 minutes, ignition attempts are carried out, the length of which is restricted to approximately 5 minutes in each case. The ignition attempts are repeated in the specified time if the flue-gas temperature has sunk below a predetermined value (for example 100 DEG C). In order to carry out this process, the invention provides a first timing circuit for restricting the adjustable time period for the sum of all the ignition attempts and a second timing circuit for restricting the maximum time period of each ignition attempt, the latter circuit being controlled by a third circuit which is switched on by a flue-gas thermostat when the flue-gas temperature falls below the predetermined flue-gas temperature.
