Abstract: 743,431. Television pick-up tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 19, 1953 [May 27, 1952], No. 14079/53. Class 39 (1). An electron discharge tube comprises a photo-conductive layer with a metallic back-plate at near cathode potential, a permeable decelerating electrode near the target and at a high potential relative to the cathode of the gun and a scanning beam producing secondary electrons and reflected primary electrons at the target to form pictures on a fluorescent screen or develop video signals or both. A very thin metallic back-plate 3, e.g. of platinum or glass supports the photo-conductive layer 4 and the very fine mesh planar grid 10 which lies close to the layer and at a high potential, e.g. 1000 volts, i.e. the potential of a wall coating 2 and the anode 8 of the inclined gun 6, 7, 8. The electron lens 11 is at a lower potential, e.g. 500 volts and its focal plane passes through the centre of deflection C of the gun. Beam electrons reflected from the charge image produced on the target 4 by the image of the object cast by lens 5 which may be of infra-red or ultraviolet radiation, are accelerated and focused through a diaphragm 16 to give a visual image. Alternatively, as in Fig. 2, (not shown), they are focused onto the first element of an electron multiplier, the final electrode of which gives a video output signal. In another modification, the primary electrons reflected at the target pass to a symmetrically placed electron multiplier to give the output signal. Fig. 5 shows an arrangement combining the two systems to provide a visual monitor, the reflected electrons being received by the electrode 12 of the multiplier 13 and the secondary electrons being accelerated along the axis on to the fluorescent screen 16.

Title: Improvements in radiotelephonic and other radio-frequency signalling systems
IPC: H03C1/20
Filed: 1924-06-18
Abstract: 239,309. Hale, G. W., and Radio Engineering Co., Ltd. June 18, 1924. Thermionic modulating systems. - Relates to modulating systems of the type in which a power oscillation and control valve are placed in series as regards the high tension supply, the cathode of the power valve operating at a high-frequency potential relative to earth. The invention consists in an arrangement wherein the high-tension supply c, Fig. 1, is connected directly to the plate of the power valve a, this plate being maintained substantially at high-frequency earth potential. The output from the oscillator a is modulated in accordance with micraphonic variations applied to the grid of the series control valve b. A condenser m prevents the high-tension voltage from shorting across the filaments of the two valves, and forces the direct-current component to flow via the plate of the control valve b. A radiofrequency choke n prevents undesirable damping of the main oscillating circuits through the varying impedance of the control-valve shunt, whilst admitting the necessary low-frequency modulating effect. The plate of the control valve may also include part of the aerial winding d as well as the choke coil n. Also the filament supply to the main valve a may pass through a part of the aerial inductance d, a balancing choke being introduced on the other side of the filament battery. As shown in Fig. 4 the potential of the plate of valve b is the same as that of the filament of valve a, the choke n being dispensed with. The filament supply from the battery t passes through the portion o of the main inductance, and a choke q is introduced for balancing purposes. A radio-frequency choke r is included in the grid circuit of the valve b to prevent high-frequency grid currents. The leak resistance h in the grid of the main valve may also be supplemented by a choke coil k.

Title: Improvements in slitting and re-winding machines
IPC: D06H7/04
Filed: 1923-06-05
Abstract: 216,696. Marks, E. C. R., (Nashua Gummed & Coated Paper Co.). June 5, 1923. Stationary-cutter apparatus.-In slitting and rewinding machines, a movable carriage having bearings for a winding arbor is raised by a motor after the completion of a set of coils to a position for readily removing the completed coils. It is arrested at an intermediate position during its subsequent downward movement for attaching the strips of material to a fresh arbor and is finally fully lowered to begin a fresh coiling operation. The invention is shown applied to a known type of machine wherein the web of material x is led from a supply roll x<2> between co-operating cutter discs 21, 22 mounted on shafts 18, 19 and is passed between guides 25 and flanges 26 on the driven winding roll 17 to the arbor 24 to form coils x<2>, the rotation of the arbor being at first effected by the engagement of a tapered pinion 27 on the roll 17 with an oppositely tapered pinion on the arbor and being subsequently effected by friction, the pinion on the arbor then being detached. The arbor 24 is mounted in rearwardly open bearings 32 provided with ledges 36 and carried by rack bars 33, slidable in the frame of the machine on rollers 34, 35 and engaged by pinions 39 on a shaft 40 having a hand wheel 41 for manual operation of the shaft. The rack bars are connected by a rod 42 and may be raised by the piston rod 43 of a pneumatic cylinder 44, the air supply to which is controlled by a valve 47 operated by a handle 49. During the winding operation, the arbor 24 rises and carries with it the rack bars 43, and when a complete coil has been wound, the valve 47 is opened to admit air to the cylinder 44 to raise the carriage to the position shown in Fig. 4, so that the coil x<1> may be rolled over the ledges 36 and tracks 37 to supports 50 and thence be slid on to an inclined track 51 leading to a disassembling table. When the valve is operated to exhaust the cylinder, the carriage is free to descend, but it is arrested in an intermediate position by the shoulder 60 of a latch bar 58, with the ledges 36 in line with an arbor holder 65, so that an arbor 24<1> may be rolled into the bearings 32 and the strips of material may be secured on the arbor by a cotter rod 64 carried in brackets 68 on a bar 69. Finally the handle 59 of the latch bar 58 is pulled to free the rack bar from the shoulder 60 and the carriage descends into position for the next coiling operation. The supports 50 for completed coils may be adjusted on the bars 38, 54 to take coils of varying sizes and the coils x<1> may be caused to exert pressure on the roll 17 by hanging weights 75 on the rod 42, whilst spare supply rolls x<2> are carried by rollers 73 on inclined tracks 71 which lead to rearwardly open bearings 70.
