  • Material processing apparatus with access state conveyor
    Patent number: 11370619
    Abstract: A material processing apparatus has a discharge conveyor that is coupled to the body of the apparatus so that it can pivot with respect to the body and be raised vertically with respect to the body. The coupling mechanism allows the pivoting and lifting of the conveyor to be performed by the same actuators. The discharge conveyor can be raised into an access state in which a transfer conveyor can be removed from the body.

  • Precoding of contention words in a fixed wireless access system
    Publication number: 20060148428
    Abstract: A fixed wireless access communications system comprises an access point and a plurality of subscriber units. Each subscriber unit (502) contends for access to a communications channel to the access point by transmitting a contention word to the access point during a contention time slot. The contention word is predistorted to compensate for the channel impulse response of the transmission channel so that the access point can decode the contention words without using equalisation. A control unit (512), which may comprise a microprocessor, loads the predistorted contention word (a) into a memory (520) and causes the stored predistorted contention word (a) to be applied to a transmitter (508) during a contention time slot when the subscriber unit (502) wishes to request a transmission channel to transmit data to the access point.
