Title: Improvements in or relating to cathode ray tubes
IPC: H04N5/74
Filed: 1936-08-01
Abstract: 479,356. Cathode-ray tubes. STRANGE, J. W., and CONNELL, W. H. Aug. 1, 1936, No. 21330. [Class 39 (i)] In cathode-ray tubes for television of the projection type employing a fluorescent screen, the mask is formed on the same surface as that on which the screen is formed and on the same side thereof. The material forming the mask must be such as to withstand. the evacuating temperatures of 300-550‹ C. When the end of the tube is formed of a sheet of optical glass sealed to the conical portion of the envelope, the fluorescent surface and the mask of heat resisting material such as vitreous enamel or metallic suspensions may be applied before sealing the parts of the envelope together. Alternatively the mask may be applied after the end plate is sealed in position and may be constituted by the metallic coating which is employed as one of the anodes. The coating may be applied by the use of a chemical silvering solution, or a conducting coating of lead sulphide or copper, or by evaporation of metals in vacuum. The coating may be removed from the area to be covered with fluorescent material or this area may be protected during the coating operation by a sheet or plate which is readily removable, e.g. a sheet of flexible material with a thin layer of low melting point wax or a coating of material soluble in a suitable solvent such as nitrocellulose or other lacquer. Where the conducting coating is applied in liquid form, the limits of the coating forming the edges of the mask may be determined by tilting the tube. The fluorescent surface may be raised or lowered slightly above or below the rest of the surface of the end plate. In a modification the fluorescent surface and mask may be formed on a plate of transparent material such as mica or opaque material such as aluminium and suspended in the tube. Specifications 383,889 and 457,951 are referred to.

Filed: 1922-08-04
Abstract: 184,195. Ges. fiir Drahtlose Telegraphie. Aug. 5, 1921, [Convention date]. Regulation, automatic systems and apparatus for.-The circuit of an alternator A, for supplying a thermionic oscillation generator through a transformer PS, includes an iron-oored choke coil C and the primary coil p of a transformer. The secondary coil s of this transformer is connected through a rectifier R to a coil E wound on the core D of the choke C. A direct current passes through the coil E proportional to the current in the alternator circuit, and any variation in the load on the alternator, due, for example, to keying the grid circuit of the valve, varies the saturation of the core and tends to keep the valve supply voltage constant. The apparatus may be arranged to keep constant the voltage across the primary coil P of the transformer, and in this case the valve filament may be connected across the coil P. The apparatus may be adjusted by connecting a variable resistance across the coils E, s, or p. A direct-current winding F may be arranged on the core D in series with a battery B and a key K or a microphone as an alternative method of telegraphic or telephonic signalling. An amplifier may be interposed between the microphone and the coil F.

Title: Improvements in or relating to frequency discriminating telegraph signal detectors
Inventor: ROBERTS PETER KEMP
IPC: H04L27/14
Filed: 1962-06-04
Abstract: 960,976. Telegraphy. MARCONI CO. Ltd. Feb. 21, 1963 [June 4, 1962], No. 21454/62. Heading H4P. A frequency discriminating frequency shift telegraph signal detector includes timing means for determining if a cycle of the signal exceeds a predetermined time duration, and means for producing one or other of two output signals depending on this result. As shown, an incoming signal (a) is amplified at 1 and shaped at 2 to give a rectangular wave output (b) which is differentiated at 3 to give a wave (c), the negative pulses of which are selected at 4 and shaped, inverted and amplified at 5 to give a pulse train (d). A short space in front of one of these pulses indicates that the pulse corresponds to a " space " signal, i.e. the higher frequency, while a longer space in front of a pulse indicates a " mark " frequency. The pulse train (d) is fed to a pair of gates G1 G2 and also to a timing device A1. The timing device A1 switches on when it receives a pulse and switches off again causing an end element 1A1 to act at the end of a period corresponding to the shortest possible time cycle of a signal. The end element 1A1 then operates to cause a second timing device A2 to produce an output to open the gate G1 during a range of time covering a cycle of any acceptable space signal, and then a third timer A3 operates for the range corresponding to the longer period " mark " signals. Thus, if after receiving one pulse which operates the timing devices A1,A2, A3 in sequence, the next pulse is a " space " pulse occurring a short distance behind the first it passes through the open gate G1 to trigger a bi-stable circuit BS to one state, while if it is a mark pulse it arrives later to find the gate G1 closed and the gate G2 open and passes through the latter to trigger the circuit BS to the other state. If the " space " frequency is more than twice the " mark " frequency, a second pulse could arrive and operate the timers A1 and A2 while the timer A3 is operating, thus opening both gates G1 and G2. In these circumstances an inhibit connection shown in broken lines ensures that the gate G2 is closed for this " space " pulse. In a modification the timers A1, A2 are combined as a single timer and the element 1 is dispensed with.
