Patent GB-760950-A (GB)
Title: Improvements relating to the generation of electrical signals employing a pick-up tube having a target of the charge storage type
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H01J31/30
Filed: 1953-11-26
Abstract: 760,950. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 18, 1954 [Nov. 26, 1953], No. 32797/53. Class 39(1). [Also in Group XL(b)] A television pick-up tube arrangement has a scanning light spot for generating signals and electron beam scanning for stabilizing the target to datum level, the latter performed in the period between the light spot scanning intervals. In Fig. 1, the mosaic target 2, 3 receives both the image scene 12 and the light spot from scanner tube 13, the latter reflected by a half silvered mirror 14. The stabilizing beam from gun 5, 6, 7 is scanned over the target and focussed by coils 8, 9. A grid 11 limits the potential to which the target can be charged. In Fig. 2 (not shown), an electron beam is produced by scanning a photo cathode with a light spot, thereby avoiding the use of scanning coils. A reference signal at the end of each line scansion representing peak white is obtained by switching off the light scanner 13. In a further modification, Fig. 4 (not shown), an electron multiplier section e.g., an apertured dynode adjacent a ring electrode, is positioned near the gun 5, 6, and receives the electrons liberated by the light spot under the control of the scanning coils. The signal is taken from the multiplier and not from the signal plate. In Fig. 5, the tube is cathode potential stabilized, with a photo cathode 26 receiving the scene and the scanning light spot. A wall anode 33 directs the photo electrons at high velocity onto a target 27 comprising a then semi-conducting glass sheet, the secondary electrons liberated at the target being collected by mesh electrode 28 from which the signal is taken. The beam from gun 5, 6, 7, discharges the target, and a blanking circuit is included in the amplifier 30 of the output, to suppress the signal due to the discharging current. Reference signals are obtained from the border region of the photo-cathode, by flooding with light from a lamp 32 through a slotted mask 31. In all examples, the stabilizing may be performed only once during every few such line periods using a defocussed beam or by causing the beam to oscillate across several lines. Alternatively the cathode is a strip giving a flat deflected beam. The specification describes the grid action of the dielectric surface between the mosaic elements and control of the potential of the wall anode to prevent the potentials of the mosaic elements rising above the first cross-over potential.

Title: Improvements in or relating to the reforming of gasoline fractions
IPC: C10G45/10
Filed: 1954-11-17
Abstract: A gasoline fraction is reformed by first removing the arsenic impurities by contacting it with an initial portion of a noble metal-containing catalyst at a temperature between 125 DEG  and 425 DEG  C. and then reforming the thus purified gasoline by passing it over a noble metal-containing catalyst at a temperature of 440-650 DEG  C.  Preferably the arsenic which may be present to the extent of about 350-400 parts per billion is removed by using a catalyst which has previously been used for the reforming step. The catalyst may be platinum, palladium, silver, or gold containing ruthenium, rhodium, osmium or iridium.  The catalyst is preferably from 0.1 to 1.0 per cent platinum on a refractory oxide such as alumina together with 0.2 to 5 per cent of halogen; other refractories which may be used include silica-alumina, silica-zirconia, silica-magnesia, silica-thoria, silica-alumina-zirconia, silica - alumina - magnesia and silica - aluminathoria.  In an example a straight run naphtha having a boiling range of 115-205 DEG  C. was passed over a catalyst comprising alumina containing 0.4 per cent of platinum, 0.3 per cent of fluorine in a first reactor at 41 atmospheres at 316 DEG  C. to remove arsenic and then in a second reactor at 34 atmospheres at 496 DEG  C. and subsequently in 3 more reactors at 496 DEG  C.ALSO:The arsenic impurities in a gasoline fraction are removed prior to reforming the gasoline by passing it over a noble metal conntaining catalyst at 440 DEG -650 DEG C., by first contacting the gasoline with an initial portion of a noble metal containing catalyst at a temperature between 125 DEG  and 425 DEG C.

Abstract: 1314907 Electronic flash-light control FRANKE & HEIDECKE GmbH [trading as ROLLEIWERKE FRANKE & HEIDECKE] 9 July 1970 [9 July 1969] 33434/70 Heading G2A A flash tube 1 is energized from a storage capacitor 4 by ignition of a thyristor 3 from an ignition device 2. When the correct exposure of a subject is reached as measured by a photoelectric integrating device 7, a thyristor 6 is ignited to discharge capacitor 5, in the opposite direction to the flash tube current, through thyristor 3 to produce a quenching impulse to tube 1. The quenching impulse is longer than the deionization time of tube 1 and the shorter recovery time of the control element. The charge taken from storage capacitor 4 is thus only that required to produce a correct exposure and the recycling time is kept to a minimum.

Abstract: 604,986. Waveguides. ALLAN, H. R., SCHEFERMANN, A. V., and WRIGHT, C. S. Dee. 11, 1945, No. 33455. [Class 40 (v)] An electrical coupling for transmitting power between a co-axial line and a waveguide comprises a mounting plate 1 carrying a probe 3 forming an extension of the inner conductor of the coaxial line, and two screws 6 so that when the mounting plate is applied to a wall of the guide, not shown, the screws 6 pass right through the guide and are held by wing nuts 7. Probe 3 also enters an aperture in the guide wall so that the enlarged end 5 lies centrally of the guide. If a coaxial line is applied to the plug coupling 2, energy is supplied to the wave guide and flows in a direction away from the screws 6 which act as short circuiting members as they are arranged a quarter wavelength apart. The device is useful for supplying energy to a receiver for testing purposes by injecting it into a waveguide which couples the receiver to an aerial. The screws 6 then prevent energy from being fed to the aerial.
