IPC: H04B3/54
Filed: 1981-02-12
Abstract: A receiver, for receiving a signal comprising a carrier signal modulated with a digital signal, comprises means for demodulating the received signal to produce an output signal which contains the digital signal. Because of repeated filtering, the digital signal is typically in the form of an approximately sinusoidal signal, which has a component whose frequency is equal to half the basic bit rate of the digital signal: because of noise, this component is subject to considerable timing jitter. To overcome this, the output signal is digitized and applied to a digital correlator, where it is correlated with a reference signal whose frequency is also equal to half the basic bit rate of the digital signal. The reference signal is preferably derived from a phase-locked loop locked to the carrier frequency. The correlator, which is constituted by a microprocessor, determines the instants of time which most nearly coincide with the mean-level crossing points of said component (which instants correspond to transitions between one bit of the digital signal and the next), and also determines successive bit values on the basis of the coincidence determination. The receiver can be used to receive mains-borne signals, i.e. signals transmitted over an electrical power supply network, or radio broadcast signals. The received signals employ at least one of two or more carrier frequencies derived from a common oscillator, and the receiver includes a phase locked loop capable of locking a local oscillator in the receiver to whichever of the carrier frequencies is being received.

Abstract: In a process for refining Al or Mg a stream of relatively impure molten metal is passed along one face of a grille separator (63) having interstices of the order of 0.1 - 1 cm in width. The interstices are filled with a molten salt electrolyte adapted to transport ions of the selected metal (Al or Mg) to a body of refined metal on the opposite side of the separator. The relatively impure metal is made the anode and the refined metal is the cathode. Refined metal is progressively withdrawn from the cathode. The grille separator may be arranged substantially vertical or substantially horizontal, usually with slight inclination. Passages are preferably provided in the separator to allow escape of gas generated at a metal/electrolyte interface.

Abstract: A method is disclosed for inputting displacements of movable bodies into an apparatus for automatically moving movable bodies to predetermined positions. Pulse signals are generated by an encoder (200) indicative of displacement of a body to a predetermined position, a unit displacement corresponding to one pulse. These pulse signals are counted by a counter (130) and the counted value is stored in a memory (107) whereby distance data are inputted based on the counted value thus stored. 
     The method can be used for controlling a machine tool, such as a boring machine, milling machine or lathe, avoiding the errors consequent on manual measurement of the distance of a workpiece in the machine from a previously established reference position.
