Abstract: 1,252,227. Cathode-ray displays. TEKTRONIX Inc. 7 April, 1970 [12 May, 1969], No. 16517/70 Heading H4T. The output of a light-pen 20 (Fig. 1) responsive to a line raster display on a monitor CRT 10 controls sampling gates 30, 32 which pass samples of the instantaneous levels of vertical (A) and horizontal (B) ramp voltages from a generator 12 to respective memories 38, 40 the generator 12 supplying, on line 14, a composite synch output which is supplied via amplifier 15 and mixer 16 together with video signals to control the formation of the monitor display and the samples C, D in memories 38, 40 being supplied to a utilization device 42 comprising e.g. an A/D converter or a " slave " X-Y monitor. A primary display comprising e.g. a graph, map or Alpha-numeric information produced by a TV camera or a computer 82 is initially produced on the monitor 10 by supplying the output of computer 82 (with switches 85, 86 in the central position) via amplifiers 70, 68 to the vertical and horizontal deflection plates 66, 64 of a direct viewing scan conversion bistable storage tube 48 to store the information on the storage electrode 52. This information is then " read ", non-destructively, in a reading cycle described below, to produce video signals for the monitor 10. Switches 85, 86 are then returned to the position shown to connect amplifiers 68, 70 to respective switches 72, 74, which are operated to the " write " position shown during the retrace periods of the horizontal ramp B by means of a pulse H from a control circuit 76 controlled by the horizontal drive output 78 of generator 12. In these positions switches 72, 74 supply the horizontal and vertical samples D, C from memories 40, 38 to amplifiers 68, 70 so that the beam of tube 48 is deflected to the X-Y co-ordinate position on electrode 52 corresponding to the position of the light-pen relative to monitor 10. The light-pen position is thus recorded as a stored charge and during the subsequent horizontal trace (switches 72, 74 in the " read " position) the horizontal and vertical ramp outputs of generator 12 are supplied via amplifiers 68, 70 to the deflection plates of tube 48 to " read " out non-destructively the stored information which is supplied via amplifier 15 together with the composite synch from generator 12 to the monitor 10. A " cursor " may also be produced on the latter without storing the charge image of the lightpen position by means of comparators 88, 90 receiving the vertical ramp A and vertical sample c and receiving the horizontal ramp B and horizontal sample D respectively to produce a pair of gating pulses IJ which, on coincidence, gate out bursts from a high frequency oscillation 92 and supply the bursts to mixer 16. The signal waveforms A to K are illustrated in Fig. 2 (not shown).

In a second arrangement the filler material and the foamable plastics material are mixed initially and then introduced into the mould. In a third arrangement part of the filler material is placed in the mould and the remainder is mixed with the foamable plashes material, the mixture then being introduced. In the arrangements in which part of or the whole of the filler material is introduced first it may comprise granular material, e.g. high-density polyethylene, PVC or glass, in the form of microballoons, or a sheet or tape of mesh material, e.g. polyethylene or glass. In the third arrangement the remainder of the filler material comprises granules of a size smaller than the granules or spacings in the mesh of the first part of the filler material. These smaller granules, which are also used in the second arrangement, are carried by the foam as it expands and are distributed throughout the mould. Examples given are sand, slate, PVC or polyethylene, in flow form, or glass, in the form of microballoons. The foamable plastics material, which can be polyurethane, epoxy, polystyrene, polyester or polypropylene, is subjected to pressure as it foams, for example it may have a greater potential volume than that available for its expansion. The conductors, and, when terminating a cable, the terminals, may be insulated prior to the introduction of the foamable plastics material.

EL device comprising a phosphor layer, capable of conducting D.C., sandwiched between two electrodes and means for applying between the electrodes an operating voltage in the form of a succession of unidirectional pulses such as to cause light pulses to be emitted from the device in phase with the voltage pulses, the pulse repetition frequency being such, in relation to the pulse duration, to produce a steady light. Reference is made to increased light emission in relation to power dissipation and the reduction of ageing in the form of a continual increase in electrical resistance. The frequency may be such that the time between pulses equals the decay time of the individual light pulses. The phosphor may be ZnS: Cu, Mn and Cl, and incorporated as a 10Á thin film deposited by evaporation. The phosphor may also be in the form of a 10Á layer of powder deposited as a dispersion in a binder. The device may be indicator lights such as in vehicle instrument panels or an alpha-numeric display. Rise times for powder and thin film layers of ZnS may be 250 and 20 Ásecs. respectively. In an embodiment, a powder phosphor layer (ZnS: Cu, Cl, Mn) is between a light transmissive electrode on a glass base, and a metal backing electrode. Operation may be by spiked or square wave forms e.g. 90 v. square pulses of 10Á width, light emission decay time being 5 ms. for a 35Á thick layer, and 250 Ásecs. rise time. A thin film of the same phosphor had a 500 Ásecs. decay time. Decay time increases with phosphor thickness.
