July 9, 1931, No. 19798. Convention date, July 17, 1930. [Classes 39 (i) and 40 (iii).] An electric image is formed from an optical image of the object to be transmitted and is scanned by cathode rays 44. The optical image is projected on a fine-mesh photoelectric cathode 11, which emits electrons 41, 43 proportionately to the illumination. These produce corresponding charges on insulated metallic inserts 15 in the anode 12. The opposite ends 16 of the inserts are scanned by a beam 44 of cathode rays which passes through a fine-mesh electrode at positive potential. The number of electrons 44a which reach the anode 13 in the neighbourhood 38 of each insert 15 varies with the charge on that insert and sets up a corresponding voltage across a resistance 25 in the grid circuit of an amplifying-valve 31 connected to a transmitter. The electrons which fall on the insert 15 discharge it by secondary emission to the screen 17. According to modifications, the mesh cathode 11 is replaced by a semitransparent photoelectric film on the inside of the cathode-ray tube 10 at its large end ; the electrodes 12, 13 are made of corrugated strips of nickel with their engaging edges spot-welded about the inserts, Figs. 7 and 8 (not shown); the electrodes 12, 13 are combined in a single electrode, Fig. 9 (not shown).

Filed: 1973-04-26
Abstract: 1424760 Radio navigation BODENSEEWERK GERATETECHNIK GmbH 26 April 1973 [12 Oct 1972] 19920/73 Heading H4D In an aircraft landing system comprising two adjacent ground radio beacons transmitting signals which respectively define at the aircraft its azimuth and elevation angle deviations #H L  and #γ L  from a predetermined (rectilinear) landing path, the azimuth deviation signal AH L  is multiplied at 26, Fig. 7, with the output A 0  from a first function generator 22 which varies with the range Ra of the aircraft from the azimuth beacon as shown in Fig. 10, to give a resultant azimuth control signal C(AZ) which is (1) directly proportional to said azimuth angle deviation #H L  (as in conventional ILS systems) when the aircraft is in an intermediate range zone R1-R2 and (2) directly proportional to the horizontal linear (distance) deviation #s (=R a .#H L ) of the aircraft from the landing path when the aircraft is in an inner range Zone O-R and preferably also when the aircraft is in an outer range zone defined by R a >R2, the slopes of the segments of the A o /R a  characteristic in said two zones being different. An elevation control signal C(EL) is produced in a corresponding manner by a second function generator 32 (output A oi ) responsive to a signal corresponding to the range R e  of the aircraft from the elevation beacon but in this case the variation of A oi  with Re in the outer distance zone R2-R3 (see Fig. 12) is such that the control signal C(EL) is inversely proportional to the linear altitude deviation #h(= R e .Aγ L ) of the aircraft from the landing path. The control signals C(AZ) and C(EL) are applied to a cross pointer indicator 30 or to an automatic pilot (not shown). The range signal R a  is given by a known form of aircraft DME unit operating in conjunction with a transponder at the azimuth beacon and the range Re is given by R e = R a -R L  where R L  is the known spacing between the azimuth and elevation beacons. When operating in mode (2), is C(AZ) directly proportional to #s, the cross pointer display 30 may be used to facilitate turning into the landing path as described with reference to Figs. 14 and 15 (not shown). As shown in Figs. 10 and 12 each A/R characteristic comprises three rectilinear segments of different slope but alternatively each said characteristic maybe in the form of an equivalent smooth curve, Fig. 11 (not shown). The circuit of a sample form of function generator producing the first two segments of the A/R characteristics shown in Figs. 10 and 12 is given in Fig. 16 (not shown). The azimuth and elevation beacons may comprise conventional ILS localizer and glide slope beacons or the azimuth beacon may comprise a Tacan beacon or a path-difference beat-frequency phase comparision system such as SETAI (see article referred to), the elevation beacon comprising a commutated aerial Doppler system.

Abstract: 631,801. Pulsing carrier frequencies. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 8, 1946, No. 20394. Convention date, Sept. 19, 1939. [Class 40 (v)] In a circuit for producing short pulses of high frequency oscillations of substantially trapezoidal shape, pulses are applied to an inductor in the anode circuit of a magnetron, the amplitude of the pulses when superimposed upon the steady D.C. anode voltage of the valve causing it to oscillate. The Figure shows a magnetron 1 which is normally non-oscillatory, pulses produced across the inductor 3 superimposed upon the steady anode voltage of the magnetron cause it to oscillate, Fig. 7 (not shown), and bursts of H.F. oscillations are thus produced. The pulses across the inductor 3 may be produced by applying a sinusoidal voltage across the transformer 14, thus producing pulses, Fig. 4 (not shown), across the inductor 9 which are amplified in the valve 5. The resistors 4, 8 prevent the inductors 3, 9 from resonating with their respective selfcapacities.
