In a radio navigation system a ground station simulates constant velocity unidirectional motion of a radio source such that direct path signals 13 have a different Doppler frequency shift than reflected signals 14 and a receiver in a craft selects the direct path signals and derives angle of elevation a therefrom. A carrier wave of frequency F-f is commutated to aerial array 1 to simulate vertical-only movement and waves of frequencies F and F-f are radiated from a fixed aerial or aerials, not shown. The direct wave path signal frequency at the craft 7-is F-f+ #f, where #f represents Doppler shift and the frequency thereat of the reflected wave is F-f-#f; in the receiver a detector 22 produces signals of frequencies f, f-#f (corresponding to the direct wave) and f+#f (corresponding to the reflected wave); a filter 24 passes a range f-#f corresponding to the range of desired glide slopes; a filter 25 passes only frequency f; a detector 26 gives a signal of frequency #f, proportional to sin a; and a frequency discriminator 28 is centred on the frequency #f corresponding to the required glide slope α R  and produces a D.C., linearly proportional to angular departure from α R , to centre-zero meter 29.

A control valve having a piston 40 for metering the flow from input 11 to outputs 21, 18 in response to the pressure drop across variable orifice 23, has an independently operated control member 38 for moving piston 40 to a position in which all of the input flow is diverted to secondary outlet 18. Member 38 is operated by a cam 51 on knob 27 which also adjusts the position of needle 24 in orifice 23. The pressure upstream of orifice 23 is communicated to a chamber 35 via bases 48, 47 where it acts on piston 40 in opposition to the pressure downstream of the orifice which passes through a fixed orifice 32 to chamber 30, thus the piston is maintained in a position to provide a substantially constant flow to primary outlet 21. Should excessive pressure build up in chamber 30 a pilot valve 55 opens so reducing the pressure on the right hand end of piston 40 so that the pressure in chamber 35 moves the piston to a position in which it diverts all of the flow into outlet 18.

The resistance R 1  may be connected to the input of a differential amplifier 18 connected to the next stage or the amplifier 2 may be a differential amplifier. In the embodiment of Fig. 4 the reference voltage is subtracted from the analogue voltage at a junction 15 the output bits from the stages being in reflected binary code. For all stages except the first the reference voltage equals ¢V max , the first stage comparing the input voltage with zero to derive a polarity bit. In the embodiment of Fig. 7 (not shown) the reference signal is only subtracted before the signal is fed to the next stage if the digital output of the stage is " 1 ".

Abstract: 1,250,835. Justifying type. INTERNATIONAL BUSINESS MACHINES CORP. 10 April, 1969 [29 April, 1968], No. 18417/69. Heading B6W. Apparatus for justifying lines of text of different predetermined lengths, by punching a tape to control a line-casting machine and also producing a printed copy of the text, includes means for reading an original tape, input storage means for the data (character identity, character width and spaces) associated with a line, means for storing a plurality of line length measures and selecting one of such measures (e.g. 1 column or ¢ column), means for computing the unjustified total width of the characters in a line, according to which total the requisite measure is selected, means for counting the number of spaces, means for calculating the width of the spaces in a justified line, and means for transferring the data to output means for transmission to the punches and the printer.
