[Also in Division G1] A cathode-ray tube 1 (Figs. 1, 2) of flat, rectangular section, comprises an electron gun 2 containing a beam forming electrode 6 with a vertical slit and a focusing electrode 7, a pair of horizontal deflection plates 3 and a fluorescent screen 4 at the end 10 of the tube at an angle to the electron beam axis, which produces a short line trace normal to the longer axis of the screen, deflectable along this axis by direct or alternating voltages proportional to an electrical quantity applied between the deflection plates. The fluorescent screen is divided along the axis into short persistance section 11 and long persistance section 11<SP>1</SP>. The light from the former 11 passes through a slit 13 into a dark box 12 where the deflections are lineally recorded on a photographic film F continuously traversed over a backing-plate 18. The light from 11<SP>1</SP> is reflected in prism 21 through lens 22 and rotary mirror 23 to the eye of an observer. In a modification (Figs. 3, 4, not shown) the beam is deflected over an arcuate fluorescent screen; provided with a calibrated scale placed inside or outside the tube. In a further modification (Fig. 5, not shown), an electron beam is focused to a narrow rectangular section deflected over a screen divided into plural rectangular sections coated with phosphors producing light of different colours or different brightness under electron impact so that coloration or brightness indicates the deflection to an observer. A multi-gun tube, or a split beam tube with two pairs of parallel deflection plates, beam forming slits and distinct fluorescent screens may be used (Figs. 6, 7, not shown).

Title: Pcm tdm exchanges
IPC: H04Q11/04
Filed: 1977-02-22
Abstract: 1508755 Automatic exchange systems SIEMENS AG 22 Feb 1977 [29 April 1976] 07372/77 Heading H4K A PCM exchange comprises switch-through units which are individually assigned to PCM tdm lines PCM1-RCM3 and each switch-through unit comprises a spatial switch and a storage unit e.g. SE1 comprising two full stores e.g. VSKJ, VSGJ one for each transmission direction, the various switch-through units being interconnected by pulses ZL1, ZL2 to form a network having a T-S-S-T structure similar to that of Specification 1,351,408. The system differs therefrom in that each switch-through unit e.g. SE1 is such that write-in of information to both incoming and outgoing full stores VSKJ, VSGJ is performed cyclically whereas each store can be read acyclically either to the outgoing PCM line PCM1g or the space switch. Each switch-through unit e.g. SE1 further includes a first holding store area HSRS which stores information for controlling the operation of its associated spatial switch crosspoints, a second holding store area HSV1 which stores drive addresses for the read-out of information to the line PCM1g, and a third holding store area HSV2 for storing drive addresses for the readout of information to the spatial switch. The above arrangement allows a switch-through unit to be used for intermediate storage or a connection between two other units between which no direct connection time slots are available, such a connector being shown by a heavy black line in the figure. The various addresses shown in Figure 3 in the stores assume that information read out of store VSKJ of unit SE1 at slot x of bus ZL1 will be written into a location corresponding to slot x + 1 in unit SE2, i.e. that there is a one slot transmission delay, between units. Further a switch-through unit can be used to establish a connection between time slots on the same highway without use of the space switching stage (Figure 4, not shown). The network can be fabricated using large scale integrated circuits.
