Title: Adjustable microwave frequency bands separator - has capacitors narrowing bandwidth in blocking waveguides junction with H-bend
Inventor: SCHUEGRAF EBERHARD DIPL ING
IPC: H01P1/213
Filed: 1979-03-30
Abstract: Sharper frequency separation of two bands is ensured by reduced characteristic impedance of the blocking section (3). A partition (9) parallel to its wide side is set in the middle of the narrow side. Wider frequency band is obtained with double blocking waveguides (7) without harmful effects due to the partition (9). The frequency separator waveguide section (I) carries both bands of 4 and 6 GHz while its continuation section (2) exhibits a narrowed cross-section for aperiodic blocking of 4 GHz. Section (2) provides a periodically non-damped transmission of the 6GHz band, the decoupling ensured by H-band (4). Port (6) in slope (5) provides damping of the lower frequency band while outlet of bend (4) opens up into section (3) featuring the blocking waveguides (7). The bandwidth of waveguides (7) is narrowed by capacitors at their junction with the section (3).

Title: Heating system control by ultrasonic transmission along pipes - using transducers clamped on pipes to transmit and receive coded signals
Inventor: KUEHNLEIN HANS DIPL PHYS
IPC: H04B11/00
Filed: 1979-09-25
Abstract: A heating system for a multi-storey building circulates hot water through pipes (8,9,10,12,15) to radiators (H11....H32). The boiler and mixing valve are controlled by a unit which is connected to an ultrasonic transducer (7) clamped to one of the pipes. Instructions and information are exchanged between this transducer and others (S2,3,Se1,3) associated with valves (V11....V32) on the radiators. Transmission is by coded bursts of ultrasound which propagates along the pipe walls throughout the system. Information is sent slowly enough for echos and multiple path effects to be unimportant. For example, all the radiators (H11,12) on the 1st storey can have motor (B11,12) driven valves (V11,12) controlled by one transducer (SE1) which reports the valve settings back. On the 2nd storey, a transducer (S2) merely reports the valve settings. On the 3rd storey, a transducer (SE3) can both control a valve (V31) and report ambient temperature from a thermometer (B31). Another transducer (S3) merely reports ambient temperature (B32).
