Abstract: The antennas (301-304) of a cellular telephone system are each connected to a signal divider/combiner array (311-314) which divides/combines the antenna connecting path(s) into a plurality of antenna-radio/radio-antenna connecting paths. The divider array aspect is used for signal reception and the combiner array aspect is used for signal transmission. Each of these antenna connecting paths is connected to a controllable switch (351-362) which in turn selectively couples it to/from a second plurality of radio transceivers (371-382). The antenna transmission/receive paths comprising the signal divider/combiners are embodied as strip type transmission lines in a multi layer PCB with all the paths having equal transmission losses. Micro vias are provided to permit electrical access to the various layers. The controllable switches are surface mounted on the outside of the PCB and are coupled to the various dividers/combiner through the micro vias. Remote control of the switches permits a radio channel unit of transceiver to be connected to any one of the array of antennas.

Abstract: A trickle filtration apparatus, designed to be sunk into the ground leaving only an upper portion of the apparatus above ground level (GL), comprises a primary settlement, tank (1a) side-by-side with a secondary settlement tank (6). Contained within the primary settlement, tank (1a) is a pump chamber (2), at the bottom of which is at least one pump (3) for pumping supernatent continuously to the top of filter media (5) in a filter tank (4) above the first-mentioned two tanks (1a,6). Supernatent trickles down the filter media (5) and is collected at the bottom to flow through a conduit (14) back to the pump chamber (2). The primary and secondary settlement tanks (1a,6) are separated by a pressure bulkhead (7), through which the conduit (14) extends. Inflow of sewage into the primary tank (1a) results in supernatent spilling out of the conduit (14) at a break point (16) into the secondary settlement tank (6), and in treated liquor spilling out of the latter (6) through an outlet (17). Oxygenation of the biomass on the filter media (5) is by natural air convection.

Abstract: A continuous process to nitrate a nitratable aromatic compound in a nitronium ion solution in a nitrator. The process comprises feeding into the nitrator nitronium ion solution of a composition within an area defined by connecting three points in a ternary phase diagram of nitric acid, sulfuric acid and water. The three points correspond to first about 82% of sulfuric acid and 18% nitric acid, secondly about 55% sulfuric acid and about 45% water and, thirdly, 100% sulfuric acid. The nitratable aromatic compound is fed into the nitronium ion solution through a spray injector able to create a fine emulsion of hydrocarbon in the nitronium ion solution with the hydrocarbon evenly distributed in the acid phase. The acid and the nitratable aromatic compound are brought into intimate contact in a plug-flow nitrator that contains mixing elements.

Abstract: To produce positive strip electrodes for primary and secondary cells in a dry process, two paste strips (6) are simultaneously rolled from powdered active material, inter alia MnO2, FeS2, CuO,   alpha -Cu2V2O7 and LixMnOy, and then fed from two sides to the nip of a cylinder mill (14) in which they are rolled onto both sides of a grid-type carrier strip which is fed into the cylinder mill between them from a reel (12). After excess paste has been skimmed off, the finished electrode strip has a thickness of less than 0.45 mm and a porosity of more than 24%.

Abstract: In the production of video devices, it is necessary to test the colour chip or the colour chip module for its operability and to compensate for production-related spreads in the operating parameters by individually calibrating the chip. Known test and measuring arrangements are set up with various measuring instruments. These are assembled as required to form a measuring system, as a result of which it is hardly possible to achieve an optimum mode of operation with respect to the measurement analysis and operating speed. According to the invention, a measuring arrangement for calibration and for functional testing of colour chip modules is specified which permits an optimum mode of operation in that the measuring and calibrating arrangement is used for directly and automatically calculating the calibration values from the measured values and supplying these to the calibrating elements. <IMAGE>

Abstract: A method and apparatus are disclosed, that is suitable for digital or analog spectrum analyzers, for accurately and rapidly ascertaining the frequency of a spectral line by interpolating its location from the response of two Gaussian shaped filters whose center frequencies bracket the frequency of the spectral line. The difference is taken between the amplitudes in decibels of the responses of the two Gaussian filters to the spectral line input signal. The frequency of the spectral line is then found from the linear relationship fx = delta-log-ampl.*c1 + c2, where c1 is proportional to the square of the standard deviation of the Gaussian filters and inversely proportional to the difference between the center frequencies, f1 and f2, of the Gaussian filters times the logarithm of e, and where c2 is the midpoint between the center frequencies, f1 and f2, of the Gaussian filters, G1 and G2. Alternatively, a sweeping local oscillator output can be mixed with the signal containing the spectral line of unknown frequency and the resulting signal applied to one Gaussian filter at two different times to produce equivalent results. In this case, c1 is proportional to the square of the standard deviation of the Gaussian filter and inversely proportional to the difference between the local oscillator frequencies, f,LO-t1 and f,LO-t2, at times t1 and t2, times the logarithm of e, and c2 is the average of the local oscillator frequencies, f,LO-t1 and f,LO-t2, plus f, the center frequency of the Gaussian filter.

Abstract: Applicable to adaptive filtering of broadband acoustic signals, the objective being to eliminate problems of acoustic echoes. 
     The method includes an additional stage for the generation of an inhibition vector (22) associated with the different segments of the filter that is fed with information from the activity monitoring stage (19) of the transmission and reception lines. The generation of the inhibition vector (22) takes into account the presence or lack of double-talking, implementing an adaption strategy that establishes the sections of the filter to be updated in each iteration. 
     The calculation of the adaption step, independent for each uninhibited filter segment in the iteration in process, takes into account the local spectral characteristics of the voice signal and includes a new computational strategy. 
     The device implements the different phases and stages of the method. 
     The invention presents the advantages to increase the rate of convergence of the algorithm regardless of the incoming signal spectral characteristics, to improve the performance of the echo canceller, and to use a single digital signal processor.

Abstract: An AC system having, for example, a voltage source (1), an inductance (2) and a load (3) has connected thereto an apparatus for controlling the phase and amplitude of the voltage of the system. The instantaneous current and voltage in the AC electrical system are measured (410, 440) and power measurements derived (430) therefrom. The power measurements may be instantaneous real and imaginary power, instantaneous active and reactive power, or active and reactive power averaged over less than one cycle. The power measurements are then used to derive (421, 422) phase related control values (Iq, Id), on the basis of which control signals are generated to a converter (42). The action of the converter (42) in accordance with the control signals thus controls the amplitude and phase of the voltage. By use of power measurements, it is not necessary to measure the phase of the voltage of the AC system.
