The material is .fed at A on to the uppermost of endless perforated belts 2 by which it is carried to and fro under successive sprays 10 - - 16 and delivered at 17. Troughs 3 - - 9 which may alternatively be arranged between the two runs of each of the belts collect the used liquids. Fresh chlorine solution delivered to the spray 15 is afterwards pumped from the trough 8 to spray 13 and then from trough 6 to sprays 10, 11, being finally discharged from troughs 3, 4. Water is supplied to spray 12 and weak acids to spray 14. Dyes &c. may be supplied to spray 16. The belts may be arranged end on end in longitudinal series. Specifications 239,722, [Class 120 (iii), Yarns &c.], and 271,938 are referred to.

Title: Improvements in or relating to electric discharge tubes for the emission of luminousrays
IPC: H01J61/35
Filed: 1932-08-13
Abstract: 386,586. Discharge lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Aug. 13, 1932, No. 22750. Convention date, Sept. 19, 1931. [Class 39 (i).] An electric discharge tube for the emission of luminous rays contains a metal vapour and is surrounded by an envelope which is coated on the side towards the discharge tube with a thin metal layer which transmits at least part of the visible rays produced by the discharge and reflects at least part of the invisible rays, more particularly the infra-red rays. In the example the discharge tube comprises a spherical bulb 1 containing an incandescent cathode 2 and an anode 3, with a filling of sodium vapour together with a gas such as argon at a pressure of 0À5 mm. of mercury to facilitate starting. The anode-supporting wire 4 may be surrounded by an insulating sheath. The surrounding glass envelope is also spherical and is coated on its inside wall with a thin layer of copper which may be applied thereto by volatilization, for example by mounting a copper-coated filament therein, exhausting the envelope, and then heating the filament to volatilize the copper. To avoid the oxidation of the copper coating when the bulb is introduced, the copper layer may be covered with a thin layer of gold, which may be volatilized from a second filament arranged inside the envelope. The gold particles may also be mixed with the copper layer. Metal vapours other than sodium may be used as a filling for the discharge tube, for example cadmium vapour, the thin metal layer upon the inside wall of the surrounding envelope then consisting of silver. The chamber formed between the discharge tube 1 and envelope 5 is entirely closed and may be exhausted, or filled with air or a gas which is a poor heat conductor. An incandescent body adapted to emit visible light, and a heater, either separately or in combination, may be arranged in the space between the discharge tube and the surrounding envelope and connected in series with the discharge tube to act as a current limiting resistance.

Abstract: 232,545. Hodeige, E. April 17, 1924, [Convention date]. Upward - current classifiers. - In means for washing and separating granular material, of the kind in which the material is fed by a horizontal stream of water along a channel into which upward currents enter, perforations through which water currents issue are disposed in the side walls, as well as in the bottom, if necessary, of an inclined trough or channel 8 through which the material passes, such currents acting on the material in a direction lateral to its direction of travel. The current, together with the lighter constituents of the material, enters the channel 7 through passages 10, 10a. A number of troughs 8 may be disposed side by side with a common upward current supply. In a complete plant, the materials may be further treated by passage along a substantially horizontal trough 11 fitted with channels 12 with perforated sides through which water from inlets 13 beneath them is passed. Heavy constituents pass through openings 14 into the compartments 14a from which they are discharged into a trough 17 leading to a further washer fitted with a number of perforated troughs 18 and supplied with water through an inlet 19. Light constituents are discharged through troughs 15, 21.

Title: A process for the production of a calcium aluminate suitable for the manufacture of sodium aluminate by treatment with soda lye
IPC: C01F7/164
Filed: 1935-08-20
Abstract: In the production of calcium aluminate by heating an aluminiferous material such as bauxite with a calcium compound such as lime, at least sufficient calcium compound is used to form with the Al2O3, SiO2, Fe2O3, an TiO2 present the compounds CaO.Al2O3, 2CaO,SiO2, 2CaO.Fe2O3 and CaOTiO2.  The ratio of the amount of calcium compound to the amount of silicic acid present is preferably increased with increasing content of silicic acid, so that whereas with a material containing 1 per cent SiO2, the amount of lime necessary to yield the compounds CaO.Al2O3, 2CaO.SiO2 is used, the amount for materials having approximately 10 per cent SiO2 is about 50 per cent higher, and the amount for materials containing 50 per cent SiO2 is about four times as high.  In carrying out the process, the finely ground initial materials may be formed into briquets with the addition of carbon, and the latter be heated to the temperature of reaction in a shaft furnace.  The pulverized product may be treated with soda lye to obtain sodium aluminate.

Abstract: 951,782. Grinding helical flutes. ARTHUR BALFOUR & CO. Ltd. July 4, 1961 [July 5, 1960], No. 23433/60. Heading B3D. A grinding machine for producing helical flutes in a workpiece 20 comprises a grinding- wheel 24 pivotally adjustable about a pivot 26 on a base 10, a slide 11 mounted on the base for reciprocation to and from the grinding-wheel, a carriage 12 pivoted at 13 on the slide for up and down tilting movement, a rotary work-holder 19 mounted in the carriage, cam-and-follower means 40, 42 for reciprocating the slide, means for tilting the carriage during movement of the slide away from the grinding-wheel so as to lift the workpiece from the latter, and means for driving the cam means and rotating the workpiece in timed relation thereto. The grinding wheel 24 and its belt-drive unit 25 are together mounted on a table 22 which is adjustable about the pivot 26, a screw 28 being provided for clamping the latter in position after inclining the grinding-wheel, left or right, to cut at the required helix angle. The slide 11 is reciprocated by a cam drum 40 having a feed and quickreturn groove 41 engaged by a follower 42 on the base 10. Upward tilting of the carriage on the return movement of the slide is effected by either a projection 48 on the drum contacting an abutment 49 on the slide or the suitable building up of the bottom of the cam groove 41. An hydraulic motor 35 drives a shaft 18 operating the workholder 19 and also the cam-shaft 39 through worm gears 37, 38 and 46, 47 interconnected by change gears 43, 45. The latter gears are selected according to the desired ratio of speed of the shafts 18, 39 and hence the desired angular relationship of successive flutes in the workpiece; for example, the ratio of the angular velocities of the shafts 18, 39 may be 3 : 2 so that for each reciprocation the workpiece rotates through 540 degrees and the second flute will be automatically formed 180 degrees out of phase with the first. To adapt the machine from the production of left-hand to right hand helices, it is necessary to reverse the inclination of the grinding-wheel 24 to the workpiece and the rotation of the hydraulic motor 35, and the same cam 40 may be used provided the arrangement permits the insertion of an idler gear between the gears 43, 45.
