Abstract: 1,145,049. Cathode-ray tube accessories. RADIO CORPORATION OF AMERICA. 28 July, 1966 [18 Aug., 1965], No. 34054/66. Heading H4T. The electromagnets, wave-shaping circuit components and control elements for effecting beam convergence of a shadow-mask colour tube are mounted on one side of an insulating plate 16, Figs. 1, 2, 4 and 5, which is apertured to receive the neck of the tube and formed with printed circuit connections on the other side, some, at least, of the supporting members for the electromagnets, which extend through the plate, also serving as electrical conductors. The electromagnet assemblies 17, 18, 19 are identical for each beam and comprise, in the case of that for the red beam, horizontal and vertical component winding assemblies 21R, 22R respectively, surrounding the core legs 23, 24 and connected to resilient (e.g. phosphor bronze) conductive strips 28, 29, 31, 32 extending through plate 16 and serving both as partial supports for the assembly and as feed conductors to the printed circuit. Thus, when the plate is positioned around the tube neck behind the deflection yoke 14 and clamped by means 15, the resilience of the strips ensures that the core legs make firm contact with the neck to effect magnetic coupling with the internal polepieces 46, 47, 48, Fig. 6 (not shown). The assembly is additionally supported by a strap 35 having a resilient projection 36 extending through the plate 16 and mechanically secured thereto, e.g. by solder. The ends 23a, 24a of the core legs are formed with arcuate faces on the (inward) adjacent sides which receive a cylindrical permanent magnet 34R, adjustment of which by means of knob 25R allows static convergence correction to be effected, the core ends being urged into contact with the magnet by means of a clip 39. A circuit diagram of a conventional dynamic convergence arrangement is described with reference to Fig. 7 (not shown) and the various elements of Fig. 2 are identified in each diagram.

Title: Digital-analogue signal converter
IPC: H03M1/00
Filed: 1964-08-21
Abstract: 1,082,115. Electric selective signalling. NIPPON ELECTRIC CO. Ltd. Aug. 21, 1964 [Aug. 26, 1963], No. 34262/64. Heading G4H. In a digital to analogue converter which has a non-linear relationship, curve 410, 411, between the input X and the output Y, means responsive to the most significant digit produces a first analogue signal and other means responsive to the remaining digits produces a second analogue which is variably attenuated under the control of the first analogue, the output of the converter being the sum of the first and variably attenuated second analogue signals. The invention described forms part of an analogue to digital converter in which an analogue input 18 feeds comparator 23 which also receives the output of digital to analogue converter 22. The digital signal is generated in unit 24 (no details) which receives the comparator output. In this embodiment the digital signal is preceded by a bit indicating the polarity of the signal. The bits control switches, which may be diode or transistor switches, 28s, 281, 282 . . . 28k. First, all switches having previously been set to their " 0 " states, the sign bit causes selection of one or other battery 26, 27, and switches 281 and 28b are set to " I " whereby a bias 42, Fig. 2, is applied to terminal 221. If the input analogue signal exceeds the bias these latter switches remain set to 1, if it does not they are set to " 0." The remaining bits then operate switches 282-28k in succession, the resistors 322-32k and 332-33k being binary weighted. The output characteristic of the weighted resistor circuit 30 is illustrated by curves 40, 43. In the event of the most significant digit being "1", bias 42 is applied as stated above. Addition of the bias 42 to curve 43 results in response 411. If the most significant digit is " 0 " the bias is not applied and attenuator 311, 312, 313 reduces curve 40 to curve 411. Further embodiments are described with reference to Figs. 6 and 7 (not shown).

Abstract: 619,009. Discharging devices for endlesschain conveyers. WOODALL-DUCKHAM (1920), Ltd., and WENBORN, E. N. Nov. 19, 1946, No. 34263. [Class 78 (i)] In a dumping mechanism for a gravity bucket conveyer of the kind comprising a retractable ramp adapted to be moved by a control member, e.g. a lever, to a dumping position in which it engages abutments on the buckets, the control member is coupled to the ramp by mechanism which permits it to be operated for the purpose of moving the ramp to dumping position at a time when such movement is prevented by stationary buckets in the path of the ramp and which mechanism operates automatically to move the ramp to dumping position as soon as the obstructing buckets have been moved. Each bucket 5 has' an abutment 6 which engages a retractable ramp 21. The ramp is under the control of a weight or spring operated over-centre device which, as shown in Fig. 1, comprises a lever 14 loaded by a weight 18 and fast on a cross-shaft 13. A toothed sector 12 free on the shaft 13 engages a toothed sector 11 fast on a shaft 8 which carries a pair of cams 9 supporting the ramps 21. A pair of driving lugs 16 fixed to the sector 12 in the path of the lever limit the angular movement of the lever relatively to the sector. The lever is turned from the stop 17, which is slightly beyond top dead-centre, until it engages the lower lug 16. In this position the lever has passed the top dead-centre, so that when the obstructing buckets are moved, the weight 18 operates automatically to rotate the cams 9 to lift the ramps 1 to contact the abutments 6 and effect tipping. The ramps are kept on the cams 9 by lateral flanges 10. The cams pass beyond dead-centre when fully operated and lock the ramp in tipping position. Each cam has three lobes 9a, 9b and 9c to effect accelerated raising of the ramp towards the end of its movement. Each ramp is rotatable on a cross-shaft 7 and to prevent jarring and oscillation comprises an extended part 19 with projecting horn 20, and convex part 30 and concave part 21. In a modification, the over-centre device is coupled to the ramp by a toggle linkage capable of locking the ramp in the discharging position.
