Title: Television method
IPC: H01J29/18
Filed: 1932-07-18
Abstract: 394,496. Television. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde-Ost, Berlin. July 18, 1932, No. 20245. Convention date, July 18, 1931. Addition to 387,536. [Class 40 (iii).] In a television transmitter employing a Braun tube as described in the parent Specification, in order to reduce the distortion in the image transmission, particularly when rapid variations in the signal currents occur, the signals are derived principally by virtue of the fluorescent effect rather than from the phosphorescent effect of the material composing the screen of the Braun type. For this purpose materials such as gypsum having relatively slight phosphorescence are employed, while the amplifier in the transmitter is designed so as to yield, as indicated in Fig. 3, a higher amplification factor V for the higher frequencies than for the lower frequencies f, the signals produced by the phosphorescent effect being so sluggish at the higher frequencies that they supply an input current of almost constant amplitude and are thereby eliminated on the output side. With such an amplifier the highfrequency components of the relatively weak currents arising from the fluorescent effect furnish, when amplified, an output potential approximately equal to that derived from the lower-frequency components of the relatively strong currents arising from the phosphorescent effect.

Catalysts containing 0.1-3 per cent combined fluorine or 0.2-5 per cent combined chlorine are preferred.ALSO:A reforming catalyst is prepared by combining a halogen, preferably fluorine or chlorine, with alumina in an amount of from 0.1 to 8 per cent by weight of the alumina, compositing platinum, which may be up to 10 per cent or more but is preferably from 0.01 to 1 per cent by weight of the catalyst, with the so-treated alumina and heating, such as from 425-650 DEG  C. The alumina which is preferably precipitated from aluminium salt solutions, especially the chloride, may be selectively worked to retain 0.2 to 5 per cent of chloride ions, or washed to reduce the chlorine content below 0.1 per cent and impregnated such as with hydrogen fluoride to provide combined fluorine in an amount of 0.1 to 3.0 per cent by weight of the alumina.  Ammonium fluoride or chloride or elemental halogens may also be employed.  An organic acid such as acetic may then be employed to peptize the alumina and the platinum thereafter incorporated by treatment with a solution of chloroplatinic acid which may or may not be treated with hydrogen sulphide prior to or during the addition to the alumina.  The catalyst is then dried, pilled, optionally reduced with hydrogen and heated.  The catalysts are suitable for hydrogenation at temperatures up to 260 DEG  C., pressures from 6.8 to 210 atmospheres and a weight hourly space velocity from 0.5-5.  Dehydrogenation conditions suitable for normal butane are 425-550 DEG  C., a pressure from atmospheric to 3.4 atmospheres and a space velocity from 200-5000.

Title: Improvements in regulating devices for high intensity arc lamps having extremely rapid ignition
IPC: H05B31/00
Filed: 1922-07-26
Abstract: 199,969. BÚnard, H. L. M. J. July 26, 1922. Arc lamps.-A high-intensity arc lamp is controlled by an electric motor which rotates constantly in the same direction, the motion being communicated through reducing gear to wheels 22, 24, Fig. 9, loose on a shaft 13, so that they rotate in opposite, directions. The shaft 13 may be connected to one or other of the wheels 22, 24 so as to withdraw or feed the electrodes by clutch discs 15, 16 secured to the core 18 of :an electromagnet E, the core being connected to the shaft by a key 17. The core is acted upon by a spring 19 the opposite end of which abuts with ball bearings against an adjustable nut 32. The wheel 22 rotates more slowly than the wheel 24 so that separation of the electrodes is slower than feeding. The electromagnet E is controlled by a relav connected across the electrodes. The motion of the shaft 13 is communicated by gearwheels 25, 26 and a clutch 41 to a shaft 27 and thence by bevel-wheels 28, 29 to a shaft 30 and bevel wheel o. The clutch 41 is fixed to a pinion 40, keyed to the shaft 27, gearing with a wheel 39 loose on the electromagnet E which may be driven through reducing gear by a hand-wheel. The clutch 41 may be disengaged from the automatic mechanism by a rocking fork 43 on a shaft 44 actuated by an external crank having a spring plunger to retain it in either of its extreme positions. The positive electrode-holder comprises a triangular frame b, Fig. 2, provided with rollers c engaging the outside of race-ways d; the negative holder is smaller to allow of its sliding within the holder b and is provided with rollers. engaging the inside of the race-ways. The holder b is provided with a nut e mounted on a screw f and the holder i is similarly mounted on a parallel screw l. The two screws are connected by gear-wheels and are driven by the bevelwheel o.
