Abstract: A DC restorer device for restoring the DC and non-zero average components of a serially transmitted binary signal which has been AC coupled. The device comprises an input port for receiving the binary signal, a clamping circuit, a feedback network, a summing node, and an output port. The input port is connected to a capacitor for AC coupling the binary signal to the summing node. The clamping circuit is also connected to the summing node. The feedback network includes an input and an output which are also connected to the summing node. The clamping circuit clamps the positive and negative peaks of the AC coupled binary signal which exceed a predetermined range. The feedback network latches the AC coupled binary signal and produces a feedback current. For a binary signal which is within the predetermined range, the clamping circuit exhibits a very high input impedance, thereby causing the feedback current to charge the coupling capacitor. The coupling capacitor produces a voltage which is added to the AC coupled binary signal at the summing node. The output port which is part of the feedback network takes the restored AC coupled binary signal and converts it to digital logic levels using a comparator. In another embodiment, the clamping circuit includes a current sensor for producing an amplitude signal which is indicative of the amplitude of the AC coupled binary signal. The amplitude signal is fed to an automatic gain controller which produces a gain control voltage for controlling the operation of a high frequency equalizer. The second embodiment of the present invention provides a DC restorer which can be merged with an automatic gain controller to provide an integrated cable equalizer in which the DC restorer and high frequency equalizer co-operate to produce a matched and high performance cable equalizer.

Abstract: The invention relates to a method and an apparatus for transferring a load (8) carried by a carrier member (12) between two mutually separate transport paths (3a, b). In such instance, the carrier member switches from being suspended in a device (4a) displaceable in the first carrier path (3a) to being suspended in a device (4b) displaceable in the second carrier path (3b). According to the method, the carrier member (12) when it is suspended by means of a first connecting device (9a, 11a) in the displaceable device (4a) of the first conveyor path (3a), is connected to the displaceable device (4b) of the second conveyor path (3b) by means of a second connecting device (9b, 11b). The length of the second connecting device is reduced and the carrier member (12) is switched thereby so as to be wholly suspended in the displacement device (4b) of the second conveyor path. In addition to the above disclosed carrier member (12) and the disclosed connecting devices (9a, 11a; 9b, 11b), the apparatus includes drive means for intake and discharge of at least one of the connecting devices in relation to the housing (14) of the apparatus for modifying the distance between the carrier member (12) and the displaceable device (4a, b).
