Abstract: 343,110. Metallic-vapour lamps. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 10, 1929, No. 30817. Convention date, Oct. 11, 1928. [Class 39 (i).] To prevent excessive collection of metal at one electrode or pole vessel, a metallic vapour arc lamp wherein part of the heat given off by the arc is conducted to the pole vessel is provided with additional means at one or more pole vessels to conduct an increasing quantity of heat from the adjacent portion of the arc to the pole metal as the level of the pole metal rises. In one form, Fig. 1, the upper portion of the pole vessel is surrounded by a sleeve x made of a good heat-conducting metal such as copper, which may be surrounded by a sleeve y of quartz or the like. In another form, Fig. 2, the arc itself is brought close to the main portion of the pole metal 1 by providing a wall or weir 3 which is common to the pole vessel and to the vertical portion 2 of the luminous tube, the wall 3 being made integral with the tube during manufacture, or attached subsequently when the vessel is made of quartz. Fig. 4 shows a pole vessel of a tube adapted to be mounted horizontally, the weir 3 being also disposed substantially horizontally. A trough or groove may be provided in the periphery of the horizontal tube to connect the electrodes so that the arc may be started by rocking the tube about its horizontal longitudinal axis. The tubes may be U-shaped and operated in a vertical, horizontal, or inclined position, and may be provided with a rib or partition for use on alternating-current circuits. Specifications 28147/04, 18264/05, 21834/08, [all in Class 39, Electric lamps &c.], 4266/11, and 211,455, [both in Class 39 (i), Electric lamps, Arc &c.], are referred to.

Abstract: 881,887. Ion-exchange. NEW CONSOLIDATED GOLD FIELDS Ltd. Sept. 11, 1959 [Sept. 11, 1958], No. 31049/59. Class 46. An ion-exchange apparatus comprises a series of flat-bottomed square cells 4 which are interconnected by apertures 8 at low levels in the party walls 9 between them so that a pulp to be treated can flow through the series of cells. The final cell 414 has an outlet pipe 10 which, in the embodiment illustrated, is flexible, so that the outlet level may be adjusted. Ion-exchange resin in slurry form is fed on the surface of the penultimate cell 413 by means of a feed pipe 11. In operation pulp is fed in to the first cell 41 by inlet 7 and solids are kept in suspension by the gentle agitation of the paddle blades 5 and 6. To smooth the swirl to some extent, baffle plates 17 are provided on the sides of each cell 4. As soon as the pulp reaches a suitable operating level, which may be adjusted by adjusting the discharge level of the pipe 10, each cell excepting the last cell 414 is charged with a pre-determined quantity of ion exchange resin on its surface. A scoop operating mechanism is also started and fresh resin in slurry form is run in through the pipe 11 at a predetermined rate to replenish resin removed from the cell 413 by the scoop 13. The cell 414 is fitted with a scoop 13 which is designed to return entrained resin coming to the surface in the cell 414 to the circuit. The cell 414 thus acts as a trap. Portions of resin are regularly withdrawn from each cell and passed to the next cell and in the cell 41 passed to other circuits.

Abstract: 265,550. New Jersey Zinc Co., (Assignees of Breyer, F. G., and Farber, C. W.). Feb. 2, 1926, [Convention date]. Pigments.-In the manufacture of lithopone, the precipitation of the barium sulphide and zinc sulphate solutions is effected in the presence of electrolytes or water-soluble compounds such as sodium or other soluble chloride, sodium or potassium sulphate, sulphuric acid &c., equivalent in amount to 0.75-1 gram of chlorine per litre of 25‹ Be zinc sulphate solution at 20‹ C. There is also established a relatively high ratio of hydrate to sulphydrate radicals in the crude pulp at the end point of the precipitation. This may be effected bv the methods described in Specifications 263,119 and 263,120, and a suitable ratio is 65-80 per cent of hydrate to 35-20 per cent of sulphydrate. The crude pulp is filter pressed and dried so as to contain 4-10 per cent of moisture, and then calcined at a temperature high enough to give the desired covering power but lower than will materially affect its lightresistance. Suitable calcination temperatures range from 725-800‹ C., and the operation is preferably carried out in an apparatus of the vertical retort type. The finished lithopone has preferably a predetermined degree of alkalinity, which if necessary may be promoted by the addition of alkaline agents or by other methods.
