Title: Astatic cathode ray tube
IPC: H01J31/04
Filed: 1948-05-07
Abstract: 655,485. Cathode-ray tubes. TRIGGS, W. W. (Farnsworth Research Corporation). May 7, 1948, No. 12597. [Class 39 (i)] In order to render a cathode-ray tube astatic two electron beams are deflected in opposite directions by the signal voltage so as to strike separate target electrodes, which are connected to the output circuit in such a manner that the signal-produced variations in electron collection are additive. In the tube shown in Fig. 1, two electron guns 2, 3 produce two electron beams 4, 5 which strike targets 6, 7. These are cross-connected as shown and are connected to an output resistor 8 the midpoint of which is connected to the positive terminal of a battery 9. The terminals of the resistor 8 are connected to a utilization circuit 10. The deflecting system consists of two pairs of plates 11, 12, one operating on each of the beams 4, 5. The plates of the pairs 11, 12 are cross-connected so that the beams 4, 5 are deflected in opposite directions in response to signals from a source 13 and produce an additive result in the output circuit. An external field would deflect both beams in the same direction and the effects would neutralize each other. In a modification, Fig. 2, in front of the cathode 15 is located an electrode 16 having two apertures 17, 18 which pass two electron beams 19, 21. These are formed into horizontal sheets 29, 31 by pairs of rods 25, 26 and 27, 28 at a higher positive potential than the electrode 16. The deflecting system comprises upper and lower plates 22, 23 and a box-shaped electrode 24 having upper and lower surfaces spaced from, and facing, the plates 22, 23. The target structure comprises a two-stage electron multiplier. Secondary electron-emissive electrodes 32, 33 are arranged in alignment with the undeflected electron sheets 29, 31 and in front of a plate electrode 34 the front surface of which is conditioned for the liberation of secondary electrons. Electron-collecting electrodes 35, 36, 37 are arranged as shown. Voltages for the various electrodes are derived from a battery 38 across which is connected a potential divider comprising a number of resistors in series. The cathode 15 is connected to the negative end 41 of the potential divider and the electrode 16 to a more positive point 42. The deflecting plates 22, 23 are connected together and to one end of an input resistor 43, the other end of which is connected to the central electrode 24. The central point of the resistor 43 is connected to a point 14 more positive than the electrode 16, whilst the rods 25, 26, 27, 28 are connected to a still more positive point 45. The collecting electrodes 35, 36 are connected together and to one terminal of an output resistor 48, the other terminal of which is connected to the centre collecting electrode 37. The centre point of the resistor 48 is connected to the positive terminal 49 of the voltage divider. The electrode 34 and the secondary emitting electrodes 32, 33 are connected to points 47, 46. A source of signals 51 is connected to the resistor 43 and a utilization circuit 52 to the resistor 48.

Abstract: 551,092. Selective signalling. SIEMENS BROS., & CO., Ltd., and DURKIN, E. W Oct. 14, 1941, No. 13206. [Class 40 (i)] [Also in Group XXXIX] In a direct current signalling system, the insertion of a rectifier in the line circuit at the sending end causes the release of a relay at the receiving end, whereupon a further relay controlled thereby operates to annul the signal by reversing the connections of the line relay. The Figure shows an arrangement for obtaining synchronous operation of two switches DML, DMA, the line circuit including opposed rectifiers MRA, MRB which are brought in alternately by relay S. In the position shown, relays T, A are up while S, R are back. If the marking is transferred to a later contact of DML, T falls back, S operates, A falls back and DMA steps. Reversing relay R now energizes, A re-operates in series with L and DML steps, whereupon S falls back and the action is repeated until the change-over of S is prevented by the operation of T. Other applications are concerned with automatic telephone exchange systems (see Group XXXIX).

Abstract: 1,255,224. Visual signalling. SANDERS ASSOCIATES Inc. 13 March, 1969 [18 March, 1968], No. 13243/69. Headings G4F and G4H. Apparatus for recognizing a coded pattern on the screen of a cathode ray tube comprises means for sensing the coded pattern, to generate a corresponding pattern of signals, and means responding to these signals to make a record. The sensing means may consist of a gun-shaped device adapted to be held in the hand and directed at one of a number of points 60, 62, 64 on the C.R.T. These may be associated with the answers to a question and the coded pattern may be a rapid sequence of flashes which is odd or even in number according as to whether the answer is wrong or right. A decoder detects a sequence indicating a right answer and energizes an oscillator to make a recording on a magnetic disc or tape. The disc or tape may be advanced by the operation of the trigger 32. Instead of using magnetic recording a current sensitive paper can be used, marked by the passage of current, or light sensitive paper marked by light, e.g. from a neon lamp. In another form a coded pattern of bits may be transmitted "1" being represented by 10 pulses, " 0 " by the absence of pulses for a similar period. A detector is provided to respond to a " 1 " signal and energize the oscillator and make a recording of the transmitted pattern.
