Abstract: 1,257,712. Cathode-ray tube circuits. R.C.A. CORPORATION. 7 March, 1969 [11 March, 1968], No. 12150/69. Heading H4T. In a convergence circuit for a multi-beam cathode-ray tube, two convergence windings, specifically the windings 1H and 2H (Fig. 1) for horizontal convergence correction of the red and green guns of a tri-gun colour display tube, are connected in series and supplied via an adjustable inductor 13 with pulses of horizontal frequency from the horizontal deflection circuit. The inductor 13 integrates the pulses and provides a sawtooth voltage which is integrated by the convergence windings to produce therein a parabolic current wave, the amplitude of which may be adjusted by adjustment of the inductor 13. During the first half of the horizontal scan period diode 18 conducts and the rectified current flowing in the windings 1H and 2H clamps the trough of the parabolic current to a fixed valve, so that static centre convergence does not change as a function of control adjustments. During the latter half of the horizontal scan, when diode 18 is non- conducting, the shunt path including resistor 17 and diode 18 has a high resistance and the amplitude of the saw-tooth may be adjusted by adjustment of potentiometer 16 in the shunt path including capacitor 14 and resistors 15 and 16 without such adjustment affecting the conditions during the first half of the scan during which adjustment is effected by means of the inductor 13. This latter adjustment, which is made first, a cross-hatch generator producing a pattern of equally spaced vertical and horizontal lines being employed, aligns the vertical red and green lines on the lefthand side of the screen (the first half of the horizontal scan) after which potentiometer 16 (the master tilt control) is adjusted to align the vertical red and green lines on the righthand side of the screen (the last half of the horizontal scan) and differential tilt control is then affected by means of potentiometer 20 to align the horizontal red and green lines. The blue horizontal convergence circuit is a known type. Component values are given.

Abstract: 1,259,055. P.P.I. radar displays. TOKYO KEIKI SEIZOSHO CO. Ltd. 12 May, 1970 [13 May, 1969], No. 22882/70. Heading H4D. In a pulse radar P.P.I. display system incorporating a range ring and a bearing marker, the latter begins at the range ring. The range ring can be set to any desired range and the direction and length of the bearing marker also can be set at will. By aligning the bearing marker with a target and its end coinciding therewith it can be monitored as to whether the target is entering a predetermined zone around the radar. In one embodiment, sources 8, 9 supplies pulses P1, P2, Fig. 3A, B synchronized with a ship's radar pulse transmission and the rotational period of the radar aerial respectively; pulses P1 after an adjustable delay 10 (which may be altered corresponding to ship's speed) are fed directly as pulses E1, Fig. 3C, to a mixer 3 to afford a range ring, the mixer being supplied also with echo pulses and to a bi-stable 13 which is set by pulses E1 and reset by pulses F1, Fig. 3D, the latter being obtained from a variable delay circuit 14. Pulses P2 after an adjustable delay 15 afford pulses F3, Fig. 3F, to trigger a monostable 16, thereby yielding pulses F4, Fig. 3G. The output of AND circuit 17 is the bearing marker signal E2, Fig. 3H. The angle of the displayed bearing marker corresponds to the delay imposed by circuit 15 and its length, to the difference between the delays in circuits 14 and 10. In operation the range ring is set to define a danger zone around the ship and the bearing marker positioned to terminate on a target; thereafter the possibility of collision can be judged, Fig. 2 (not shown). The foregoing embodiment assumes that the angular velocity of the radar aerial does not fluctuate; this can be allowed for in a further embodiment, Fig. 4 (not shown). In the above embodiments the P.P.I. incorporates a rotating deflection yoke; in another embodiment resolved time-bases are employed, Fig. 5 (not shown).

Abstract: 1,267,089. Aerials; radio direction-finders. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 18 Aug., 1969 [17 Aug., 1968], No. 41118/69. Headings H4A and H4D.  A direction-finder aerial is arranged so that it can be used both as a frame aerial and an Adcock aerial. As described, two pairs of parallel vertical dipoles 1-1, 2-2 and 3-3, 4-4, Fig. 1, are provided with respective horizontal interconnections 5 at their upper and lower ends and with switching devices 6, from which they are fed. The two devices 6 are interconnected, and frame aerial voltages are developed at upper terminals 7 and Adcock aerial voltages at lower terminals 8. In the Adcock aerial mode the two dipoles of each pair are effectively in parallel (Fig. 2a, not shown) and the two pairs provide an H-type aerial. In the frame aerial mode the upper and lower arms of the dipoles of each pair provide with their interconnections, two loops in parallel (Fig. 2b, not shown). The switching devices 6 each comprise a transformer 19, Fig. 3, the windings of which are cross-connected between pairs of terminals 11-13, 12-14 associated with the respective dipoles of a pair. The transformer windings present a very high impedance to the currents due to the aerial elements acting as dipoles, but pass the currents due to the aerial elements acting as loops. Hence, a voltage may be picked up at terminals 15, 16 which is substantially due only to frame aerial action. Pairs of capacitors 24-24 are connected between terminals 11, 12 and 13, 14 and, by using a frequency for Adcock aerial operation which is considerably higher than that used for frame aerial operation, they may be arranged to pass the Adcock aerial signals and to block the frame aerial signals. Suitable frequencies are 20-80 MHz (Adcock) and 5 MHz (frame). The voltages due to the Adcock aerial action may be picked up at terminals 20, 21 at the centres of respective windings 22, 23 of an additional transformer connected between each pair of capacitors 24-24. Two of the aerials shown in Fig. 1 may be arranged to form a combined crossed H-type Adcock aerial and crossed-loop aerial.

Abstract: 1290720 Television THOMSON CSF 30 Dec 1969 [30 Dec 1968 20 Jan 1969] 63378/69 Heading H4F [Also in Division H1] To impart relative adjustments, in gain, black level, or gamma correction exponent, to three primary colour signals whilst maintaining the overall signal level constant, three linear rotary potentiometers PR, PB, PV, one in each channel and controlling, e.g. the gain or black level thereof as a linear function of angular setting, are arranged at the corners of an isosceles triangle and are coupled to a single lever 10 by arcuate slotted slides 4-6 so that when the lever is moved about a ball joint 11 the total variation of impedance presented by the potentiometers is at least approximately zero. For relative adjustment of the gamma factor, each signal is fed to a circuit with a logarithmic transfer function which is variable by means of one of the potentiometers, and then fed to a circuit with a constant antilog transfer function. The potentiometer shafts 1-3 may extend radially of the slides at their points of connection and they may intersect equi-angularly and be coplanar or relatively inclined, or they may be parallel. It is possible to visualize the correction made to the signals from the position of the lever with respect to the showing of a colour triangle centred on the joint 11, Fig. 3 (not shown), but a clearer representation is obtained using the circuit of Fig. 4. The potentiometers are provided with a source of constant potential and the variable potentials at the taps are used to adjust the relevant parameter, e.g. gain, of a corresponding circuit. Resistors 18, 19 and galvanometers 16, 17 give an indication of the potential between pairs of the taps. The galvanometer needles 13, 14 rotate about two apices of a displayed equilateral colour triangle and lie along symmetry axes thereof when no current flows, so that the point of intersection of the needles shows the relative adjustment effected.

Normally cable 2 is held in an inoperative position by a pulley 22 intermediate its ends being pulled into a pulley 18 on the rig 1 by a housing cable 19. When the restraint of cable 19 on cable 2 is removed the cable 2 straightens out under the influence of a weight 23. A liferaft 26 can then be lowered down the cable 2. The raft 26 has a painter 35 attached to cable 2. The cable 2 is attached to a drum 8 on the rig 1 to which drum is also fixed a cable 24 holding the weight 23. Thus when there is no restraint by cable 19 on cable 2 the weight 23 moves down, thus rotating the drum 8 and straightening the cable 2. The housing cable leads from pulley 22 round pulley 18 to a braked housing winch 21.

The nitroquinoline is reduced to the amino-quinoline using stannous chloride and the product optionally treated with an alkylating agent, e.g. methanolic CH 2 O + Raney Ni+H 2  or triethyl phosphite, to give a dialkylamino quinolone. Quinol-4-ones are prepared by the reaction of an ester of p-fluorosulphonyl benzoyl acetic acid and p-benzoyl amido aniline followed by treatment with diphenyl, diphenyl oxide or an amine derivative thereof to give an oily intermediate which is cyclized with the elimination of an alcohol at elevated temperature to yield a mono or di-nuclear quinolone. Quinol-2-thiones are made by the reaction of a keto-ester with an aromatic amine to give an amido derivative which is isolated and cyclized. The cyclized product after isolation is treated with an ester of p-toluene sulphonic acid to afford a tertiary amine which is isolated and treated with P 2 S 5  to give the thione. An alternative preparative scheme uses a secondary aromatic amine instead of a primary aromatic amine and omits the alkylation step. Quinol-4-thiones are prepared from a 4-chloro quinoline by successive reaction with an alkyl iodide and sodium hydrogen sulphide with isolation of the intermediate quarternary iodide. Quinoline derivatives wherein X is an oxime or an imino group are derived from a 4-chloroquinoline by reaction with dimethyl sulphate to give a quartenary compound and then either hydroxylamine or an aromatic amine respectively. Quinolines with an acyl-substituted hydrazone group in the 4-position can be prepared by a method analogous to that immediately above but using an acyl hydrazine instead of hydroxylamine. A quinoline derivative where X is dicyanomethylene is prepared by the reaction of N - isopropyl - 2 - methylmercapto - 4,7 - dimethylquinolinium iodide and propane dinitrile in a mixture of pyridine and piperidine. Many other compounds are specified.
