Abstract: The present invention refers to a broadband antenna configured for processing at least two frequency bands or radio standards in a radio communications system, the broadband antenna including at least one column, the column including at least one antenna element, a first phase shifter configured for phase shifting a first frequency band or radio standard and a second phase shifter configured for phase shifting a second frequency band or radio standard, and a diplexer configured for diplexing the phase shifted first and second frequency bands or radio standards, including two inputs and one output, with the first phase shifter and the second phase shifter being coupled to the two inputs, and the antenna element being coupled to the output. The invention further refers to a radio base station system including a broadband antenna according to the invention.

Abstract: The thermal load of an electrical component is used as a basis to limit an electric current through the electrical component, in particular the rotor winding of a turbogenerator. This reliably avoids overheating of the component and at the same time achieves full exhaustion of the electric current, particularly in the case of field forcing.

Abstract: A process for the separation of a mixture of waste. In order to improve such a process, the mixture is treated biologically, namely composted and/or stabilized under forced ventilation. The components of the mixture are subsequently separated into a combustible fraction and a non-combustible fraction, whereby the non-combustible fraction contains less than 5% organic substances.

Abstract: Apparatus for cleaning a toilet brush includes a splash proof housing, which surrounds the toilet brush and has a bottom provided with an outlet for spent water, and a supply line leading to the housing. To permit simple, reliable and effective cleaning of the toilet brush, nozzles are provided in the housing, which are directed toward the toilet brush.

Abstract: A clock voltage supply for electronic control circuits such as a computer system for generating four clock signals which are synchronous as to frequency and phase. When n=4, the clock signals are generated with the help of four PLL clocks. So that the four clock signals can continue to appear even if one of the four clocks is malfunctioning, the clock signals of the four clocks are supplied to four (3:4) voters from whose outputs the clock signals are then supplied. Since each voter circuit brings about a certain delay time, which significantly limits the frequency of the clock signals, a delay element is connected downstream to each of the voter outputs respectively. The delay time of the respective delay element, plus the delay time of the respective voter connected therewith, is an integral multiple of the period of the intended clock frequency. For PLL control, the output of each delay element gives the nominal phase position and the output of each clock gives the actual phase position.
