Title: Improvements in and relating to chromium
IPC: C01G37/14
Filed: 1963-06-10
Abstract: Hexavalent chromium values are recovered from waste mud streams from a chrome ore roasting process by first reacting the product with water.  The aq. soln. containing water-soluble hexavalent Cr is separated from the undissolved solids which contain acid soluble Cr values.  The solids are treated with CO2 in the presence of alkali metal hydroxide or carbonate (e.g. sodium) in amount not substantially less than that stoichiometrically equivalent to the hexavalent Cr, calculated as alkali metal chromate, and the pH adjusted to 7.5 to 10.  The solids are finally separated. The solids may be held in suspension (e.g. by stirring) during passage of CO2. The resultant filtrate may be fed back in contact with the roast of the leaching step.  The initial mud may have a pH > 10.5 and be fed into a suspension of NO2CO3 having a pH of 8 to 10.  CO2 used in carbonation may be diluted with a nonreactive gas; roaster gas containing 5 to 20% CO2 is suitable.

Title: Production of hydrogen fractions enriched in deuterium
IPC: C01B4/00
Filed: 1963-06-17
Abstract: <PICT:1008475/C1/1> A deuterium - enriched hydrogen fraction is produced from elementary hydrogen by subjecting the latter at temperatures below - 100 DEG  C. to the reaction 2HD = H2+D2 by contact with a composition capable of both catalytically promoting the isotope exchange reaction and preferentially adsorbing either deuterium or hydrogen at the reaction temperature. The adsorbed fraction may be recovered by desorption.  By continuously recycling one fraction pure D2 may be recovered.  Suitable adsorbing catalysts include metallic iron, nickel or tungsten of surface area at least 1 m2/gm., prepared by reduction of the corresponding oxide; silica or alumina may be used in addition to the catalytic adsorbent. Vertical adorption column 1 has catalyst inlet 2 and outlet 6, feed-gas inlet 3 and overhead gas outlet 4, desorbed gas outlet 5. In an example a Co-conversion catalyst consisting of 96% Fe2O3, 4% Cr2O3 was reduced with dry H2, cooled in an inert gas (He, A) to - 150 DEG  C. and introduced into section A of column 1 together with hydrogen containing 0.015% deuterium. Adsorption, rectifying and stripping sections A, B, C were maintained at - 195 DEG , - 195 DEG , - 150 DEG C. respectively.  The reflux ratio of the ascending gas was such as to produce 0.15% deuterium in the bottom product.  (This may be fed into other columns for further enrichment.)

Title: Improvements in or relating to television transmitting apparatus
IPC: H04N3/40
Filed: 1948-09-17
Abstract: 656,069. Cathode-ray tubes. WEIGHTON, D., and PYE, Ltd. Sept. 17, 1948, No. 24406. [Class 39 (i)] [Also in Group XL (b)] A television pick-up tube of the image iconoscope type comprises an evacuated envelope containing a photo-cathode and a target on to which electrons emitted from the photocathode are to be directed, the electron gun for providing a scanning beam within the envelope being omitted and the target being scanned by scanning the photo-cathode with a beam of light. The evacuated envelope 7 is provided at one end with a photo-cathode 6 carried by the inner surface of the envelope. A target or mosaic electrode 8 is mounted on one side of a support, on the other side of which is a signal plate 9. An accelerating electrode 11, formed by a conductive coating on the inner surface of the envelope, and a focusing coil 10 transfer an electron image emitted from the photo-cathode 6 to the target 8. The electron beam of a cathode-ray tube 1 is focused by a coil 3 and deflected by coils 2 so as to form a raster on the fluorescent screen. The light from this screen is reflected by a half-silvered mirror 5 and focused by a lens 4 on to the photocathode 6. At the same time the light from the scene to be transmitted is focused by a lens 15 to form an image on the photo-cathode 6 after passing through the half-silvered mirror 5. A scanning beam of electrons is generated at the photo-cathode 6 due to the light from the cathode-ray tube 1 and is accelerated and focused on the surface of the target by the same electrode 11 and coil 10 that accelerate and focus the electrons emitted due to the optical image so that any distortions resulting from the electrostatic and electromagnetic means employed are equal for both and consequently do not affect the picture signal. The charges of each element of surface of the target are discharged in turn by the scanning beam and the discharge current flows through a resistor 12 connected to the signal electrode 9, which is capacitively associated with the target 8. Potentials corresponding to the picture signals are developed across the resistor 12 and are fed to an amplifier 14. Instead of using a halfsilvered mirror, an optical image of the spot on the screen of the cathode-ray tube 1 may be projected obliquely on to the photo-cathode 6. The target 8 may be formed as a mosaic of discrete particles capable of retaining the charge image. The picture signal may be obtained from the accelerating electrode 11 instead of from the signal plate 9. The pick-up tube may also include further accelerating electrodes or auxiliary electrodes such as electron multipliers.

Title: Tabletting Press
IPC: B30B11/00
Filed: 1968-05-23
Abstract: 1,154,289. Tabletting press. KILIAN & CO. G.m.b.H. 23 May, 1968 [29 June, 1967], No. 24589/68. Heading B5A. [Also in Division G3] A rotary tabletting press having means by which the feed volume in a feed zone of the press is varied in dependence upon the moulding pressure in a pressing zone thereby to keep the weight of the tablets constant comprises a die plate 10 having cavities 11, lower and upper punches 12 and 13, lower and upper pressure rollers 15 and 19. The lower pressure roller 15 being mounted on an eccentric lever 16 which is loaded by an adjustable compression spring 17 so as to be normally pressed against a fixed stop, a feed zone A where the cavities are charged and a compression zone B where final compression of the feed stock is carried out. When the tablet formed is released from the press the pressure is so high that the eccentric lever 16 is moved against the pressure of spring 17. If the lever is displaced to position 22 the weight of the tablet is correct. If displaced to position 23 or 24 the lever closes a switch 25 or 26 in the circuit of servomotor 29 in which circuit there is also a rotary switch 30 connected to the die plate through a gear-wheel 31. In each pressing position the circuit is closed only once during each pressing cycle by switch 30 at the time when the pressure in zone B reaches its maximum so that if one of switches 25 or 26 is closed at this time the motor 29 can act through gears 33 and 34 to raise a lower cam plate 35 for the lower punch 12 in feed zone A. If the circuit is closed by switch 25 (i.e. the tablet is too tight) the cam plate 35 is lowered, punch 12 is withdrawn and the volume of the die cavity increased. In another embodiment a resistance strain gauge in strip form is used to measure the maximum moulding pressure.
