Abstract: Crushing mill including a crushing chamber, an inlet pipe of the refuse to be crushed connected to the crushing chamber, and a thruster member associated to the inlet pipe; the crushing mill includes a compactor apparatus for the refuse to be crushed provided with one or more presser elements positioned in correspondence to the inlet pipe of the refuse to be crushed and configured to be moved from at least a first inactive position, in which they allow the loading of the refuse to be crushed into the inlet pipe, to at least a second active position in which they compact the refuse in the pipe; the mass of compacted refuse in the inlet pipe is sent to the crushing chamber by means of the thruster member.

Abstract: A crushing mill includes a crushing chamber and a feed unit to feed the waste to be crushed positioned upstream of the crushing chamber. Upstream of the feed unit a first aperture is positioned for the inlet of the waste to be treated in the feed unit and, downstream of the feed unit, a second transfer aperture is positioned to transfer the waste to be treated toward the crushing chamber. The feed unit includes a member rotatable around a determinate axis and provided with at least a pair of cylindrical sectors angularly offset with respect to the axis, provided with corresponding inlet and discharge apertures of the waste to be crushed and configured so that, in any loading and/or crushing step of the waste to be crushed in the crushing mill, they prevent the first and second apertures from coming into communication with each other.

Abstract: Method and system for reducing interference between adjacent antennas wherein one antenna transmits a first signal from a transmitter equipment and a second antenna receives a second signal by a receiver equipment, the first and the second signals may have the same frequency, and the angular discrimination between the TX antenna and the RX antenna in the same location is low. The transmitter equipment inputs an intermediate frequency contribution of the first signal into a cross-polar interference canceller, included in the receiver equipment, for reducing a co-channel interference in the receiver equipment caused by the first and the second signals, wherein the cross-polar interference canceller selects a desired signal from the two signals received so as to reduce said interference.

Abstract: A method and apparatus are described for transmitting/receiving a Gigabit-Ethernet signal by a high capacity point-to-point radio system. The basic idea consists in transmitting a Gigabit Ethernet interface using a single frequency in a channel plan of about 56 MHz bandwidth. The invention is based on a technology that combines forward error correction, cross polarization interference cancellation (XPIC), base-band signal processing, adaptive equalization and antenna's interconnection. In the best configuration, two carrier frequencies, H and V polarized, are selected in order to have the required bandwidth for easily transporting a Gigabit Ethernet. A proper compression rate can be selected according to the available resources; in case of radio channel failure, the compression rate can be changed. Ethernet frames are mapped by a Generic Framing Procedure encapsulation protocol.

Abstract: A mill for shredding scrap, comprising a shredding chamber able to contain scrap during the shredding and having a shredding unit, an inlet pipe connected to an opening of the shredding chamber, in order to transfer the scrap toward the shredding chamber. The mill comprises first thrust means associated with the inlet pipe, selectively movable between a loading position of the scrap into the inlet pipe and one or more intermediate positions to transfer by means of thrusting the scrap toward the shredding chamber. The mill also comprises second thrust means, disposed in proximity with the inlet of the shredding chamber, selectively movable between an inactive position, in which they do not interfere with the introduction of the scrap into the shredding chamber by the first thrust means, and one or more thrust positions in which they introduce into the shredding chamber the scrap moved by the first thrust means until the scrap is in proximity with the opening.

Abstract: Described is a method and apparatus for mapping Fast Ethernet data interfaces (in addition to possible data interfaces of different type) into a single VC-4 Virtual Container of a STM-1/OC-3 payload transmitted to a radio-link system. The method is characterized by the steps of: packeting the Fast Ethernet signal and any other signal, mapping the packets into a single (VC-4) Virtual Container of a STM-1/OC-3 payload of a SDH/SONET signal frame, and transmitting said signal frame through the point-to-point radio-link, said radio link being a point-to-point SDH/SONET radio link. All the packets have the same format and are associated to a header for identifying the source. The interfaces of different type are conveniently grouped. Possibly, the VC-4 is filled with null packets to exhaust the maximum available capacity.

Abstract: Described is a method and system for increasing the spectrum efficiency in a radio transmission system. Advantageously, the interference phenomenon is used for transmitting two different signals, by utilizing for each of them carriers at the same frequency, thus obtaining in this way a doubling of the spectrum efficiency. Practically, the same signal is transmitted by two different antennas in order to have two coherent signal sources. On the receiving front, there are points of maximum and minimum of this signal. If the original signal is properly phase shifted with an antenna vis-à-vis the other one, the effect will be to arrange the maxima and minima on the receiving front in a corresponding way. The present invention allows for the use of dual polarization antennas (H and V or any other type of orthogonal polarization) to obtain a still higher spectrum efficiency.

Abstract: A method and device is described for converting an STM-1 signal into a sub-STM-1 signal in synchronous radio transmission. The invention provides for the use of a pure regenerator network element without any multiplexing function. The method according to the invention provides in transmission, for reducing the received STM-1 signal by one third (only the first TUG-3 is considered as valid and is transmitted in the radio link, whereas the second and the third TUG-3 are considered in an unequipped condition and are not transmitted), thus maintaining the STM-1 structure. In reception, the method provides for reconstructing the signal with the complete regenaration of the payload and the correct structure of the AU-4 without incurring any parity control infringement.

Abstract: A method is described for transmitting/receiving STM-4 (SDH) or STS-12 (SONET) digital signals over two RF carriers in a radio regenerator section. The method provides for performing, in transmission, a de-interleaving operation of the standard frame to be transmitted in such a way as to subdivide it by columns into two sub-frames. The RSOH bytes of the standard frame are terminated and transmitted over the two working channels or over one service channel and one working channel so as to be protected in a 1+1 configuration: In reception, a column interleaving operation recombines together the two sub-frames and recovers and correctly rearranges the RSOH bytes so terminated as to obtain the standard frame originally received from the transmitter. The generated sub-frames are synchronized with the standard frame.

Abstract: Described is a packet switching mechanism for packet data transmission systems in a multi-channel radio arrangement. The method comprises the steps of receiving a plurality of data packets (A, B, C, . . . ) to be transmitted; and providing a number (n+p) of radio channels (VC-X#1, VC#X-2, . . . ) for performing the transmission. The method is characterized by the steps of assigning the entire transport of each data packet (A, B, C, . . . ) to one radio channel (VC-X#1, VC#X-2, . . . ) and, in absence of failures, by performing the transmission by using all the available working and protection channels.
