    摘要: Apparatus for a radio local loop for a telecommunications system, such as a base station (1) or a subscriber station (2), comprises a first unit (4, 13), which includes call processing and speech transcoding/encryption apparatus (8, 17), and which can be housed in a friendly environment, such as within a telephone exchange or within a subscriber's premises, and a comparatively rugged second unit (3, 14) which includes a modem (11, 22) and radio transceiver (12, 23), and which can be housed, in the case of a base station, at a site remote from the exchange, but central for the subscribers which it is to serve, and in the case of a subscriber station on the outside of the subscriber's premises. The first and second units are linked by a base-band link (5, 15).

    摘要: A cooling system for an industrial facility includes a facility that has a thermal energy output and an input, a dry cooler that includes a plurality of blowers, an evaporative cooling tower, a fluid-cooled chiller, a valving system that receives a thermally-charged media from the thermal energy output for delivery to at least one of the dry cooler, the evaporative cooling tower, and the fluid-cooled chiller, and a temperature sensor that is in communication with the valving system via a controller. The temperature sensor measures a current ambient temperature and cooperates with the controller to automatically adjust the valving system to direct the thermally-charged media to one of the dry cooler, the evaporative cooling tower, and the fluid-cooled chiller for rejecting heat from the thermally-charged media to define a thermally-receptive media. The cooling system further includes a return conduit that delivers the thermally-receptive media to the input.

    摘要: The invention relates to a composition comprising anionic clay and rare earth metal hydroxy carbonate. This composition can suitably be used in FCC for the reduction of NOx and/or SOx emissions, the reduction of the S and/or N-content in fuels, and as a metal trap.The composition can be prepared by precipitating a divalent metal salt, a trivalent metal salt, and a rare earth metal salt to form a precipitate, calcining the precipitate at 200-800° C., and rehydrating the precipitate in the presence of a carbonate source to form a composition comprising anionic clay and a rare earth metal hydroxy carbonate.

    摘要: A method and apparatus is disclosed to overcome the effects of intersymbol interference during data transmission. Overcoming the effects of intersymbol interference makes possible higher data transmission rates for a given error rate. In one embodiment a receiver-transmitter pair is configured with a precode filter at the transmit side and a feed forward filter and a feedback filter at the receive side. Filter coefficients are calculated to reduce the undesirable effects of the channel, such as intersymbol interference. In one embodiment a training process occurs with the feedforward filter and a feedback filter, such that the first N coefficients of the feedback filter are set to zero. Thereafter, the coefficients of the feedforward filter are subject to spectral factorization and separated into minimum phase roots and maximum phase roots. The minimum phase roots comprise the precode filter coefficients and the maximum phase roots are established as feedforward filter coefficients.

    摘要: A method of controlling a delay locked loop (DLL) in a memory device is provided. The DLL generates an internal clock signal based on an external clock signal. The DLL constantly responds to variations in operating condition of the memory device to keep the external and internal clock synchronized. The method involves preventing the DLL from responding to a change in operating condition such as a change in the supply voltage of the memory device during an operational mode of the memory device such as an active mode, a read mode, or a refresh mode.

    摘要: The present invention provides a spring offset device structured to extend between a circuit breaker frame and a trip mechanism. The offset device includes an offset member disposed on a trip device banana link, a spring anchor disposed on the frame assembly, and a spring extending between the offset member and the spring anchor. The spring anchor is spaced from the hatchet pin assembly and, preferably positioned so that the longitudinal axis of the spring remains on a single side of a hatchet pin assembly axis as the banana link moves between a closed position, an open position, and a reset position. The offset member and the spring anchor are structured so that, when the hatchet plate is in the closed position, the spring creates an opening force on the hatchet plate biasing the hatchet plate toward the open position, and when the hatchet plate is in the reset position, the spring creates a closing force on the hatchet plate biasing the hatchet plate toward the closed position.
