Device includes means to feed metal terminally associated with a connection conveyor including a loading plane and cooperating with translation and positioning means. Connection conveyor able to assume first position during continuous loading step, wherein its front terminal end is located substantially flush with the furnace internal wall through the aperture, to introduce metal inside the furnace; a second position distanced from the furnace wall during the step of tapping liquid metal from the furnace; and a third position while first loading the furnace, with the furnace switched off, wherein its loading plane front end is inside the furnace volume to be disposed in proximity to the distal internal wall opposite the furnace proximal internal wall, to unload and distribute a charge to cover at least part of the furnace bottom surface. | 09-20-2012 |
20140042676 | DEVICE TO INJECT SOLID MATERIAL INTO A BATH OF LIQUID METAL, AND CORRESPONDING METHOD - Device and method for injecting solid material in particles, powder or granulated form, of varying grain size. The device comprises a tubular pipe which can be applied on a lateral wall of a melting furnace so as to dispose its exit end inside the volume of the melting furnace and above the meniscus of the liquid metal. The device also comprises a chamber or tank to contain the solid material and emitter means comprising valve means which can be selectively opened for an opening time in the range of tenths of a second, to introduce an impulsive jet of pre-compressed gas or air which, in coordination with the opening of an exit valve which can be selectively opened, disposed at one end of said pipe, determines the emission of an impulsive flow of the solid material contained in said chamber or tank, with high kinetic energy and quantity of motion. | 02-13-2014 |

20090221246 | METHOD AND SYSTEM FOR CALIBRATING QUADRATURE MODULATORS - A calibration method and system for reducing modulation errors in a telecommunication transmitter apparatus includes providing a pair of test signals, which are substantially in quadrature to each other, and to repeat an estimation loop. The estimation loop starts with generating a modulated signal by modulating the test signals (the modulation introducing a modulation error) and continues by obtaining a squared signal corresponding to the square of the modulated signal. A transformed signal corresponding to the squared signal in the frequency domain is then calculated. The estimation loop further includes calculating an error indicator, indicative of the modulation error, according to the modulus of the transformed signal. A compensation, to be applied to the test signals for counterbalancing the modulation error, is calculated according to the error indicator and is then applied to the test signals. The estimation loop is repeated until the error indicator reaches a threshold and an indication of the compensation resulting from a last iteration of the estimation loop is stored (for the application of the compensation to each pair of operative signals managed by the telecommunication transmitter apparatus during operation thereof). | 09-03-2009 |
20090221247 | METHOD AND SYSTEM FOR CALIBRATING QUADRATURE MODULATORS - A calibration method for reducing modulation errors in a telecommunication transmitter apparatus includes providing a plurality of pairs of test signals; the test signals of each pair are substantially in quadrature to each other, and the pairs of test signals are at least in part different with all the pairs of test signals that have a substantially equal energy. A plurality of modulated signals are generated, with each modulated signal that is generated by modulating a corresponding pair of test signals. A plurality of transformed signals are calculated, each one corresponding to the square of a corresponding modulated signal in the frequency domain. A plurality of partial error indicators are calculated, each one as a function of the modulus of a corresponding transformed signal. The partial error indicators are indicative of the modulation errors associated with the modulated signals. A compensation for counterbalancing the modulation errors is calculated according to a combination of the partial error indicators and an indication of the compensation is stored for the application of the compensation to each further pair of operative signals during operation of the telecommunication transmitter apparatus. | 09-03-2009 |

20110320916 | METHOD OF LIST DECODING AND RELATIVE DECODER FOR LDPC CODES - A method is for generating, for each check node related to a parity check equation of a LDPC code, signals representing a first output table of corrected values of symbols of a word received through a communication channel and transmitted according to the LDPC code, and signals representing a second output table of the logarithm of the ratio between the respective probability of correctness of the values of same coordinates in the first output table and their corresponding maximum probability of correctness. The method is implemented by processing the components of a first input table of values of a Galois Field of symbols that may have been transmitted and of a second input table of corresponding probability of correctness of each value. | 12-29-2011 |
20120020400 | METHOD FOR IDENTIFYING RECEIVED SYMBOLS CORRUPTED BY BURST NOISE AND RELATED DEVICE - A method for identifying a corrupted received signal at a receiver is described. A received signal may include symbols. Each symbol may have a value of a Galois field associated therewith. The receiver may be configured to store a logarithm of normalized probability mass functions and corresponding Galois field values for each of the plurality of symbols. The normalized probability mass functions may be normalized with respect to a greatest probability mass function of a given symbol of the plurality of symbols. The method may include comparing, for each of the plurality of symbols, a logarithm of normalized probability of an n-th best probability value with a respective threshold, counting a number of the logarithms that exceed the respective threshold and generating, for each of the plurality of symbols, a score corresponding to the number. The method may also include calculating a moving average of the scores, and comparing the calculated moving average with an output threshold and flagging a just received one of the plurality of symbols as corrupted based upon the comparison. | 01-26-2012 |
