[Also in Division F2] A settling tank, e.g. for cleaning liquid used in a hydraulic power system, comprises at least a first compartment 1 into which liquid is fed through a tube 13 opening into a bucket 14 the top of which forms a submerged weir, and at least one other compartment 4 having an exposed weir 12 above the level of the submerged weir, a partition between the two compartments having an aperture spaced from its bottom so as to form a settling zone for solids below it and a flotation zone for oil impurities above it. As shown, additional compartments 2, 3 are arranged between the compartments 1 and 4 and apertures 17, 22, 26 are arranged so that the liquid must follow a tortuous path. Sloping sills 23, 24, 27, 28 trap oil, and magnets 25 remove ferrous impurities. The weir 12 leads to a compartment 11 having a sill 31 and a woven wire mesh filter 30 through which the liquid passes into a reservoir T. Sediment may be removed by removing plugs 19 and 32-35. The plug 19 may be a pivotally mounted half-spherical member, Fig. 2 (not shown), which may be pushed inwardly by a rod. In a modification, Figs. 3-5 (not shown), the apertures in the partitions (other than the aperture 17) are arranged at alternate sides so that the liquid flows to and fro across the tank. A removable perforated baffle plate (130) may be arranged across each compartment below the level of the liquid but above the apertures.

Digital data is transmitted as a frequency modulated signal which comprises a waveform whose frequency varies smoothly from a base frequency # 0  to a higher frequency f+ or to a lower frequency #-, according to the bit-state, and back to # 0  in each bit interval. In such a signal the phase of the base frequency at the end of a bit period differs from that at the beginning of the period, and the direction of the phase change indicates the bit state. Transmitter.-Polar input bits, in which the voltage during each bit varies smoothly from zero to positive or negative and back to zero, pass to a tunnel diode oscillator whose output frequency varies correspondingly about # 0 . The amplitude of the input bits is such that the phase shift in the base frequency over each bit period is 90 degrees. Receiver.-The signal passes to a hybrid unit which delivers equal components, one via a 1-bit delay and 90 degree phase shifter, to a second hybrid which provides signals on its outputs depending on the instantaneous relative phase at the inputs, the signals being combined by resistors to provide the original data. Timing.-The received signal is passed to a frequency discriminator which feeds a full wave rectifier to provide a clock signal.
