Title: Improvements in or relating to electric discharge apparatus containing a gas absorbent material
IPC: H01J7/18
Filed: 1952-01-08
Abstract: 757,481. Modifying metallic surfaces. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARESETABLISSEMENTS CLAUDE-PAZ & SILVA. Jan. 8, 1952 [Jan. 12, 1951], No. 593/52. Class 82(2). [Also in Groups XXXVI and XL(a)] An electrode for discharge apparatus, particularly a lamp, incorporates a getter material comprising tantalum and/or zirconium grains superficially oxidised to form a thin film thereon. The oxidising can be effected before the grains are mixed with the emissive material of the electrode or during the formation of the emissive material in situ. In the latter case the coiled-coil tungsten filament 15, Fig. 5, can be coated with a mixture of hydrated baryta 14 and tantalum grains 16 and an electric current is passed through the coil 15 to melt the baryta. The electrode together with a similar electrode is then mounted in a discharge apparatus which is degassed by heating in a vacuum which also dehydrates the baryta. The apparatus is then filled with a rare gas and a succession of discharges is passed between the electrodes to reduce part of the baryta to metallic barium, the tantalum grains being surface oxidised by the baryta and by the traces of oxygen-containing gas evolved during the treatment thereof. Instead of baryta, compounds of other alkaline earth metals, mixed or not with barium compounds, or thorium oxide can be used.

Title: Apparatus for the photographic printing of colour transparencies
IPC: G03B27/73
Filed: 1958-01-07
Abstract: 878,298. Colour printing. AGFA A. G. Jan. 7, 1958 [Jan. 12, 1957], No. 671/58. Class 40(3) In apparatus for the automatic photographic printing of colour transparencies by three partial exposures via different colour filters, the partial exposures are controlled by a photoelectric arrangement and the filter changing mechanism is controlled by a relay circuit. Light from a printing lamp 4 is directed to a printing frame 10 via a filler assembly 17, 18, 19 which includes three filters 14, 15, 16. The filters are normally held out of the printing beam by springs 26, 27, 28 but the energization of one of solenoids 20, 21, 22 draws its associated filter into the printing beam against the action of its associated spring. The printing frame 10 includes a transluscent screen 11, a reflector 12 and a photo-multiplier 13 of an exposure regulating arrangement. In operation, actuation of push button 39, Fig. 2, operates a relay 38 which via one of its contacts 38c, Fig. 3, operates in turn two flip-flop relays 49 and 50 which energize a relay 43 controlling the current through solenoid 20, whereby filter 14 is drawn into its operating position. In addition, contact 43b switches potentiometer 30 into the exposure control circuit to set the gain of that circuit when printing via filter 14. Thyratron valve 61 is also triggered whereby relay 60 in its anode circuit is energized, this relay switches on the printing lamp 4 at its contact 60c and removes a short circuit across an integrating condenser 34 of the exposure regulating arrangement at its contact 60d. During the partial exposure via filter 14 condenser 34 is charged by the output current of the photomultiplier 13 and when this charge reaches a preset value thyratron 35 triggers and operates relay 38. At contact 38c, thyratron 61 is cut off and relay 60 releases terminating the exposure by switching off the printing lamp at contact 60c and shorting out the charge on condenser 34 at its contact 60d. In addition the two flip-flop relays 49 and 50 are again energized releasing relay 43 whereby solenoid 20 is de-energized and filter 14 released and energizing relay 44 whereby the next filter is drawn into position. After a time delay determined by the charge on condenser 63 thyratron 60 is again triggered and the next partial exposure automatically proceeds. Specifications 805,891, 817,277 and 863,606 are referred to.
