Title: Improvements in or relating to electrostatic deflecting means for cathode ray tubes
IPC: H01J29/74
Filed: 1954-07-16
Abstract: 773,368. Cathode-ray tubes. TELEFUNKEN GES. July 16, 1954 [July 18, 1953], No. 20734/54. Class 39(1). In a cathode ray tube preferably a receiving tube, having electrostatic deflecting plates, the plates are so constructed as to provide a flat deflecting field, i.e. their width is greater than their separation which tends to impart astigmatism to the beam and a localised field having a diminishing strength from the axis outwards in a plane perpendicular to the plane of deflection at a point between the beam entry and exit portions in such a manner that astigmatism of the beam during deflection is substantially reduced or eliminated. The desired reduction in field strength in a plane perpendicular to the plane of deflection is obtained by channel shaped depressions 5, Figs. 1, 3 in the deflecting plates 3, 4 or by apertures backed by troughs, Fig. 4 (not shown). The troughs act as screens from other electrodes e.g. an accelerating anode. Both the width of the plates and the spacing between them increase in the direction of travel of the beam. In another embodiment, Fig. 5, the desired reduction in field strength is obtained by making portions 10, 11 narrower than in Figs. 1-4. The narrowest part 10 of the plates is smaller than the spacing between the plates. Extra screens which may be similar to those of Fig. 4 near part 10 may be required toprevent fields of other electrodes from penetrating the deflection field. It is explained that the astigmatism causes the spot to become elliptical the major axis of the ellipse lying in the direction of deflection so that a reduction of field in a perpendicular direction as above described compensates for this, provided that symmetrical deflection potentials are used. For asymmetrical deflection potentials however, the astigmatism is over-compensated due to field distortion produced by the conventional screen electrode between the two pairs of deflecting plates, so causing the beam cross section to be elliptical with a major axis perpendicular to the direction of deflection. This is compensated by cutting away a small part of both plates at 7, Fig. 5, which makes the field at the exit end increase away from the axis perpendicular to the plane of deflection.. The deflecting plates which may be the pair nearer to the cathode, may be secured by arms to insulating rods which also support the cathode and any further intermediate electrodes.

Abstract: 768,456. Aircraft indicators. SMITH & SONS, (ENGLAND), Ltd., S. July 14, 1955 [July 16, 1954], No. 20852/54. Class 4. An aircraft instrument comprises a first index 13, 14, rotatable in a plane about an axis 5 in accordance with the angle of roll, a second index 23, 24, the two indices being shaped and disposed so that their relative angular disposition indicates the aircraft bank relative to the horizontal, a first pointer 16 linked to the first index so as to be displaceable from a datum in accordance with bank and a second pointer 19 displacable from the datum in accordance with a required angle of bank, so that when the two pointers coincide, the aircraft is in the required bank altitude. The second index is displaceable in accordance with the aircraft pitch. In Fig. 1, the index 13, 14 and the pointer 16 are controlled by a milliammeter 6, the axis of which coincides with axis 5. The pointer 19 is rotatable about the same axis by a milliammeter 17. The second index 23, 24, comprises also a circular portion 25, and is controlled vertically by a milliammeter 20. The portion 25 co-operates with a pitch scale 28 secured by arm 30 to the casing of a milliammeter 21, the movement of which controls a pointer 27 moveable over the pitch scale. A knob 35 can adjust the pitch scale 28 and pointer 27 vertically, without effecting their relative position, by rotating meter 21 bodily about the axis of its movement. The meter 6 is connected to a pick-off 36 on a gyro vertical 37, Fig. 5, so that the index 13, 14 and pointer 16 indicate the bank angle. The meter 20 is connected to a second pick-off 45, so that the index 23, 24, 25 is adjusted in accordance with pitch. The meter 17, controlling pointer 19, is connected to a summing device 38, connectable through switch 39 to a gyro-compass 41, so that the pointer 19 is displaced from its datum in accordance with deviation from a required heading. By closing switch 43, the meter 17 is connected to an output from a radio beacon receiver 44, so that displacement from the beacon track displaces pointer 19. Switch 39 can add a rate of approach signal derived from a rate amplifier 42. Meter 21 can be connected by switch 46 to a second output from the beacon receiver 44, so that deviation in pitch from the required glide path moves pointer 27. In this case, knob 35 is used to adjust scale 28 in accordance with the known angle of glide required. Meter 21 may also be connected to a height responsive device 48, an airspeed responsive device 50, or each, so that pointer 27 can be observed when flying at constant height, constant speed, or in steady level flight. Specification 586,506 [Group XXXVIII] is referred to.

Abstract: 136,636. Lanston Monotype Corporation, (Lanston Monotype Machine Co.). Dec. 18, 1918. Single-type composing and casting machines.- In machines having a movable die-case and a buffer for preventing abnormal movement, means is provided for withdrawing the buffer and moving the die-case into an abnormal position in which it is unlocked and can be removed. The invention is shown applied to a machine of the class described in Specification 8633/99, in which the die-case 3 has a hook connexion 5<a>, Fig. 3, with a cross-slide 5 and can slide in a carrier 9 slidable on a frame 8 which is movable vertically by lever mechanism 7, abnormal movement being prevented by a buffer consisting of a lever 17 of fibre which is arranged between the frame 8 and projections 1<1> on the standard 1. According to the invention, the buffer is withdrawn and the frame 8 is raised by means of a hand-lever 25 pivoted at 25<1> to a spindle 21 which can rock in a bracket 20 on the standard 1, the lever having an arm 26 for engaging the yoke 15 of the frame 8, and the spindle having an arm 27 for engaging the buffer lever 17. In operation, the lever 7 is first employed to raise the centring-pin 2 and to raise the frame 8 into proximity to the buffer. The hand-lever 25 is then moved laterally from a stop 29 to a stop 30 and causes the arm 27 to withdraw the buffer. In the lateral movement, an incline 31 engages the hand-lever and causes the end 26 to ride beneath the yoke 15. While in engagement with the stop 30, the hand-lever is depressed into a notch 32, thus causing the end 26 to raise the yoke until the frame 8 engages the projections 1<1>. The die-case is then out of engagement with the cross-slide 5 and can be removed. The hand-lever may be operated by the left hand, and the die-case removed by the right-hand. The hand-lever is returned to the normal position by a returning-spring 18 connected to the buffer.

[Class 40 (v)] In direction-find ing, a visible and continuous record is taken in such a way that the D.F. minima are repeated in regular succession and alignment so that they can readily be identified and distinguished from the false minima due tc fading. As shown, the signals from a rotating radiogoniometer coil E are fed through sliprings C to a receiver D, fitted with headphones K. They are then passed through a rectifier E and applied directly to a stylus G which records the direction-indicating minima so that they all lie on a line parallel to the axis of the drum F. Fluctuations due to fading are not regularly orientated. The record may be made on a disc, so that the minima lie along the same radius. Instead of using a stylus, the record may be made by a mirror-galvanometer which controls the incidence of a ray of light on a strip of photographic paper. Specifications 173,510, [Class 40 (v)], 363,374, and 375,372 are referred to.
