Title: Improvements in or relating to apparatus for measuring electrical power at high frequencies
IPC: G01R21/00
Filed: 1951-05-04
Abstract: 708,538. Power measurements. GENERAL ELECTRIC CO., Ltd., FISHER, F. J., and HUNT, G. J. April 24, 1952 [May 4, 1951] No. 10509/51. Class 37. In apparatus for measuring power at single frequencies an adjustable impedance matching device is connected between input terminals of the apparatus and a resistive load, whilst a valve voltmeter is connected across the input terminals. If the impedance matching device is adjusted so that there is a predetermined impedance across the input terminals, the voltage across them is a measure of the power dissipated. A coaxial input socket 1 has connected across it a resistance load 2 and a matching network 3 comprising an inductance 5 and variable condensers 6, 7. The load 2 is formed by four carbon resistors 4 each having a resistance of 140 ohms, so that the resistance of the load 2 is 35 ohms. The network 3 is arranged to provide an input impedance across the socket 1 of 75 ohms resistive at the frequency at which measurements are to be made, by adjusting the condensers 6, 7. Also connected across the input socket 1 is a valve voltmeter comprising a diode 9, the anode 11 being connected to the inner contact 12, and the cathode 13 being connected through a milliammeter 14 to the earthed socket contact 15. An earthed screen 16 surrounds the diode 9, network 3, and load 2, the cathode and heater leads being brought out through lead-through condensers 17, 21. In series with the milliammeter 14 are a fixed resistor 22 and a variable resistor 23, a condenser 24 being connected across the meter. The standing current through the meter is backed off by means of a diode 25 having fixed and variable resistors 28, 29 in the cathode circuit. By means of a switch 31 a larger condenser 32, e.g. 8 microfarads, is connected in parallel with the condenser 17 during calibration at low frequency, e.g. 50 cycles per second. A blower driven by a motor may be arranged to force cooling air over the resistors 4. Specification 708,536 is referred to.

Title: Improvements in and relating to signalling systems, such for example as television systems
IPC: H04N5/08
Filed: 1933-04-13
Abstract: 422,824. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, WILLANS, P. W., 18, Park Hill Road, Hampstead, London, PERCIVAL, W. S., 6, York Mansions, York Avenue, Hanwell, WHITE, E. L. C., 18, The Drive, Hillingdon, both in Middlesex, and OSBORNE, H. E. F., (Representative of OSBORNE, C. P.), 56, Alcester Street, Devonport. April 13, 1933, Nos. 10522 /34 (divided out of 422,906), and 3945/34. [Class 40 (iii)] The circuits of a television system are such that the amplitude of the separated synchronizing signals is unaffected by changes in the average intensity of the picture signals. At the transmitter a direct-current amplifier is used, or, if an ordinary amplifier is used, the lost direct-current component is re-inserted by a circuit described in Specification 422,906 and based on the fact that the synchronizing signals, which exceed the signals corresponding to black in the picture, are of constant amplitude, Figs. 1-7 (not shown). At the receiver the anode of a detecting pentode 48 is connected directly to the grid of a valve 59. The potentials supplied to the valves from potentiometers 49, 53, are such that the valve 59 passes current only in response to the synchronizing signals. The line-control signals are separated from the framing impulses by a filter 62 and control a saw-tooth oscillator 67. According to a modification, separate detectors are used for the picture and synchronizing signals, each designed to operate on the appropriate amplitudes, Fig. 9 (not shown). The saw-tooth oscillations are generated by gas-discharge tubes as described in Specification 400,976. Specification 413,561 also is referred to.

Abstract: 626,545. Ironing. PROSPERITY CO., Inc. April 22, 1947, No. 10699. Convention date, June 5, 1940. [Class 138 (ii)] A method of machine-ironing shirts in which the cuffs, collar and neckband, yoke and shoulders, sleeves, back and front of the shirt are successively ironed in any order, successive ironing operations overlapping a previously ironed portion of the shirt. A battery of swinging hand-type ironing machines are used, the shirt being manually transferred from one machine to the next. The machines which may be used in any appropriate order comprise two sleeve ironers 12, a cuff and collar ironer 17, a yoke and shoulder ironer 21, a front ironer 25 and a back ironer 28.

Patent GB-707150-A (GB)
Title: Manufacture of metallic powders
IPC: B22F9/22
Filed: 1951-05-07
Abstract: In the manufacture of metallic powders the metal is dissolved in an acid, the carbonate of the metal precipitated by ammonium carbonate, the washed and dried precipitate decomposed by heat and the resulting oxide reduced by hydrogen in one or more operations at a temperature of at least 500 DEG C.  Scrap metal, e.g. iron, may be dissolved in 25 per cent. sulphuric acid, an excess of iron being present, and the carbonate precipitated from the solution formed.  The final reduction is performed by using the hydrogen obtained from the solution of the metal in acid, and the ammonium carbonate may be formed by treating ammonia with the carbon dioxide produced during decomposition of the carbonate.  The final reduction may be in two stages, the first almost complete reduction of the carbonate at 600-650 DEG C. followed by crushing, screening, and complete reduction at a temperature of at least 500 DEG C. and preferably above that of the first reduction. In a modification, the iron carbonate may be directly reduced by a first reduction at 350-450 DEG C. in a small amount of hydrogen and thereafter increasing the amount of hydrogen and raising the temperature to at least 500 DEG C.

Title: Improvements in and relating to television and like systems
IPC: H04N5/08
Filed: 1935-04-09
Abstract: 456,651. Television. MANIFOLD, M. BOWMAN-, Heathcot, Worplesdon Station, Surrey. April 9, 1935, No. 11005. [Class 40 (iii)] In intercalated scanning, line-synchronizing and field-traversal signals are transmitted in the same phase in intervals between trains of picture signals, and a receiver generates oscillations for field traversal with a duration equal to the time occupied by scanning a whole number of lines plus a fraction of a line. Each synchronizing pulse on the grid of a valve 2 blocks the valve, and a condenser 4 charges to a positive potential dependent on the duration of the pulse. The positive potential on the cathode of a valve 12 and a diode 9 is greater than the peak voltage due to a line-synchronizing pulse, but a field-traversal pulse causes current to flow through the diode and a transformer winding 10 and trigger a blocking oscillator 14. The voltage at the cathode of the diode is varied by a potential of saw-tooth wave form at half the frequency of field-traversal, which is set up across resistances 35, 36 by an oscillator 23. The oscillator 14 is thus triggered at a different value of the charge on the condenser 4 in successive field-traversal pulses. A delay circuit 21, 22 ensures that the oscillator 23 is triggered slightly later than the oscillator 14 to prevent reaction. According to a modification the derived field-traversal pulses and the saw-tooth wave at half the frequency of field traversal are applied together to the grid of the field-traversal oscillator, Fig. 2 (not shown). Specifications 425,220, 448,031, and 455,375 are referred to.
