Cells; diaphragms; electrodes; non-metallic substances, obtaining; liquids and organic substances, obtaining; liquids and organic substances, treating.-Various products are obtained by the use of an aqueous electrolyte yielding alkali-metal ions at a cathode which is so small relatively to the anode that with a high potential difference, say 30-250 volts, the cathode becomes heated above 120‹ C. and preferably to incandescence. Substances to be treated are introduced through a passage in the cathode in the form of solutions, emulsions, suspensions, or gases. One or both electrodes may be movable. A central rod electrode and a disc or cylinder electrode may be employed. As shown, the cathode 1 is surrounded, except at the ends, by a porcelain sheath 2. Suitable metals for the cathode are iron, nickel, platinum, iridium, and osmium. The anode may be the cell wall 4, of compressed carbon, iron, nickel, or copper. It is shown with flanges bolted to a flat cover and base of vulcanite, glass, asbestos, &c. A cylindrical diaphragm 7 of earthenware, fire clay, cement, asbestos, &c. extends from the cover nearly to the, base, or in some cases into a groove in the base. An overflow 18 leads to a pump which may return the liquid to the cell. Separate circulation of anode and cathode liquids may be provided for. Gases escape at atmospheric or reduced pressure. The electrolyte may contain alkali-metal hydrates, carbonates, or, if the diaphragm completely separates the electrodes, sulphates, phosphates, chlorates, organic-acid salts,- &c. Catalytic action is exerted by the alkali metal and in some cases by platinum, palladium, nickel, iron, copper, or mercury, added as salts to the electrolyte. Tar oil emulsified with soda or potash lye and introduced through the cathode bore gives cracked and hydrogenized products. The oil may be treated three times. Raw naphtha and heavy oils yield naphthenes and high-boiling products suitable for lubricants. Hydrocarbons, resin oils, or suspended coal, peat, or cellulose substances may be treated. Phenols may be reduced to benzol &c. Carbon monoxide and dioxide give fatty acids, or, with benzol &c., aromatic acids. Unsaturated and other organic acids give saturated and cracked products and also polymers.

Title: Improvements in or relating to fluid pressure operated blowers for cleaning tubes ofsteam generators and the like
IPC: F28G3/16
Filed: 1940-05-29
Abstract: 542,242. Soot-blowers. IVOR POWER SPECIALITY CO., Ltd., and MOSES, R. I. May 29,1940, No. 9417. [Class 99 (ii)] A rotating blower tube 1, Fig. 2, which slides over a stationary fluid supply conduit 9 is driven through gearing with the wheel 7 of which the blower tube has a screw connection so as to advance the tube into its operative position. Admission of steam to the conduit 9 is controlled by a compound valve actuated through a rod 36, a bell-crank 32 and a ball 31 with which engages a cam 24 on a sleeve 8 secured to the blower tube. A pawl 27, Fig. 4, carried by a fixed casing 17 holds the sleeve 8 against rotation in a clockwise direction by engaging a pin 20 thus ensuring that the cam remains out of contact with the ball 31 when the blower tube is retracted. The compound valve comprises a pilot valve 49, Fig. 5, which is driven from the rod 36 and a main steam admission valve 51 in which the pilot valve is housed. Steam is admitted to the back of the pilot valve through passages between the sleeve 52 and the main valve. In the form of blower shown in Fig. 8 there is no provision for advancing and retracting the blower tube ; the tube is rotated by a wheel 7 and projects always beyond the furnace or boiler wall 1<SP>1</SP> being supported at its driven end by a steam supply conduit 9 on which bears a sleeve 1a secured to the blower tube. The valve cam 24, which is similar to that shown in Figs. 2 and 4, is mounted on a sleeve 7a having an internal thread which engages a similar screw thread on the sleeve la. Should it be necessary to reverse the direction of rotation of the blower the sleeve 7a slides on the tube 1a and moves the cam out of line with the ball 31 thus putting the steam admission valves out of action. Specification 487,861 is referred to.

IPC: C13B20/00
Filed: 1922-04-03
Abstract: 194,948. Stewart & Co., Ltd., D., (Mauss, W.). April 3, 1922. No Patent granted (Sealing fee not paid). Separate heater and evaporator apparatus.- Liquid such as sugar juice which has been raised to a high pressure and temperature in order to coagulate albumens is brought to normal pressure and a corresponding temperature by stages during which the vapour liberated escapes freely, so as to avoid breaking up the coagulated masses. The hot liquid passes from a pipe E up a pipe A to a chamber G provided with a loaded relief valve K which maintains a pressure in the chamber less than that in the pipe E by that due to a column of the liquid of the height of the pipe A. The pipe A is inclined to facilitate escape of vapour as it is generated. The liquid is separated from the vapour in the chamber G by a perforated baffle J and passes over a ' weir H down an inclined pipe B whence it passes up an inclined pipe A<1> to a second chamber G<1> the pressure in which is less than that in the chamber G by an amount just sufficient to maintain a liquid seal at the junction of the pipes B and A<1>. From the chamber G<1> the liquid passes at decreasing pressures through another chamber G<2> or a series of such chambers connected to the chamber G<1> and to each other in a manner similar to that already described and escapes through an upcast pipe C.
