Title: Improvements in and relating to methods and apparatus for maintaining gaseous conduction discharges
IPC: H01J61/54
Filed: 1923-06-06
Abstract: 221,547. British Thomson-Houston Co., Ltd., (General Electric Co.). June 6, 1923. Vacuum tubes.-In a gaseous lamp in which the discharge consists substantially of the positive column, the discharge space between the electrodes is confined to a tube of substantially the same cross-section as both electrodes but is in communication with the surrounding bulb. The main electrodes are spaced at a distance greater than the striking distance for low potential, and means responsive to low potential are arranged to ionise the gas and to allow positive column discharge to begin. The ionising means may consist (1) of a short gap in parallel with the main gap which gives a barely-visible discharge; (2) of radioactive materials, or (3) of tungsten helices forming all or part of the main electrodes and giving some kind of ionising discharge at low potential. Three constructions of the auxiliary-gap type are described. The first comprises a bulb 1 containing rare gases, in which are mounted main electrodes 5, Fig. 1, which are in series with a limiting resistance 9. The electrodes 5 are enclosed in a transparent tube 6 of length greater than its diameter, and they have extensions 7 which form the auxiliary gap and are themselves slidingly fitted in a tube 8. In a modification, the auxiliary gap is exterior to and at a distance from the main gap, the tube 6 having closed ends and a central opening. In the construction shown in Fig. 3, electrodes 7 are placed adjacent one or both main electrodes, the discharge tube 12 having extensions -enclosing the electrodes and communicating at 13 with the interior of the bulb. The tubes 8 are preferably sealed at the ends remote from the electrodes 5, but otherwise are of such length as to confine the discharge thereto. The electrodes are made of or treated with material of high electron emissivity. A lamp is described in which the electrodes 5 are ¥" apart and the electrodes 7 are 1-32" apart. Other figures for pressures and dimensions are also stated.

Specification 370,705) in caustic soda and sodium sulphide with addition of sodium sulphate; a blueish-red shade is obtained after oxidation and by subsequent treatment with a copper salt and acetic acid a violet fast to light is obtained; a table showing the shades obtained by similar dyestuffs is given.  (3) Cotton is dyed as in (1) with the dyestuff p-p<1>-dithioaniline \sQ a -naphthylamine (c.f. Specification 365,937); a brown dyeing is obtained after oxidation which may be diazotized on the fibre and developed with b -naphthol.  (4) Same as (1) except that instead of adding the sodium sulphate immediately after dissolution of the dyestuff, the solution is allowed to stand three hours; a red is obtained.  (5) Viscose is dyed as in (1) with p-p<1>-dithioaniline \sQ b -naphthol.  (6) Acetate silk is dyed as in (1); a vivid orange-red shade is obtained and using 4 : 4<1>-diaminodiphenyldisulphide \sQ bis - 4 - (2<1>-hydroxy-3<1>-naphthoylamino)-diphenyldisulphide a blueish-red is obtained.  (7) Cotton is dyed as in (1) with the dyestuff p-p<1>-dithioaniline \sQ b -naphthol and after oxidation the cotton is reintroduced into the same bath whereby the depth of the red dyeing is thus increased.  (8) Cotton which has been dyed as in (1) with the dyestuff p-p<1>-dithioaniline \sQ b -naphthol is introduced after oxidation into a second bath containing the dyestuff p-p<1>-dithioaniline \sQ 1-phenyl-3-methyl-5-pyrazolone.

Abstract: 1500583 Data processing and display INTERNATIONAL BUSINESS MACHINES CORP 11 April 1975 [4 June 1974] 14929/75 Addition to 1408770 Heading H4T The data processing system described in parent Specification is modified by provision of staggering between timing (STROBE) pulses 64 in alternate scans, the time-delay which provides the stagger being less than the interval between the pulses, whereby the beginning or end of sampled events (e.g. pulses 61) occurring between a given timing pulse 64 and the corresponding staggered timing pulse 64' is represented by the superposition of symbols 65, 62 respectively representing presence and absence of event. By this means, a more accurate representation of the beginning and end of the events is displayed. The system is further improved by including a time-correction circuit for compensation of the time delay in the synchronization loop which tests the slope of the STROBE trigger pulses (see Fig. 2 of Specification 1,408,770). The time between a positive detection and data display in the second column of the display matrix (the first is blank), is then equal to the time between data display in the second and third (and subsequent) columns.

Title: Improvements in and relating to pulse generators comprising thermionic valves
IPC: H03K5/1536
Filed: 1945-06-14
Abstract: 615,420. Pulse generating circuits; radiolocation. SPERRY GYROSCOPE CO., Inc. June 14, 1945, No. 15192. Convention date, June 14, 1944. [Classes 40 (vi) and 40 (vii)] A pulse generator particularly for use in a radio object indicating and measuring set, comprises a sinusoidal voltage which is amplified, applied to a series circuit of the same resonant frequency and to a saturated reactor, thus producing sharp voltage pulses at the change-over points of the sinusoidal waveform, negative feedback and delayed A.V.C. being applied to the amplifier to render the phase of the pulses with respect to the sinusoidal source substantially independent of voltage supply and valve characteristics. In Fig. 1, voltage from a sinusoidal source 16 is applied to a voltage amplifier stage 12, the output being applied to the circuit 13 resonant at the input frequency. A sinusoidal current thus passes through the saturated reactor 14 and produces sharp pulses 42 in the output circuit. Negative feedback is applied from the tuned circuit 13 to the grid 26 via condenser 36. Valve 11 comprises a diode rectifier used for automatic volume control; grid 24 is held at a positive potential by the voltage divider 38, 39, valve 11 operating at maximum gain until the A.V.C. voltage overcomes this potential, causing grid 24 to swing negative and reduce the gain of the stage. Fig. 2 shows the application of pulse generators of this type in an object locating and range measuring system. One pulse generator 47 triggers the transmitter 44 with a pulse bearing an accurately fixed phase relationship to the sine wave source 16 which may be, for example, a 100 kc/s. crystal controlled oscillator. A second pulse generator 48 produces indicator time reference pulses accurately related in phase to source 16. The range of an object is indicated by comparison of the position of the reference pulse with respect to the reflected pulse which is received by receiver 45 and applied as a brightening voltage to the grid of the cathode-ray tube indicator 46. The horizontal scale of the screen of the cathode-ray tube 46 may be calibrated in terms of range and the calibration can be made independent of the circuit stability by using a null method utilizing phase shifters 57 and 58 for adjusting the position of the reference pulse on the screen to coincide with the position of the reflected signal. The constant phase angle pulse generators 47, 48 ensure that the phase angle of the pulse generated relative to that of the source 16 will not vary with signal strength, voltage supply regulation or valve characteristics.
