Abstract: 672,266. Thermionic valves. PHILIPS ELECTRICAL, Ltd. July 19, 1949 [July 22, 1948], No. 18978/49. Class 39 (i). A method of manufacturing electron discharge tubes having small inter - electrode spacings is characterized in that at least one of the electrodes between which the small spacing must be adjusted is arranged in a metal cylinder which is adjustable in the axial direction of the electrode system and the electrodes are heated while in contact with one another to a temperature exceeding the operation temperature, the adjustable electrode then being secured in place by soldering. In the Figure the cathode 6 of a diode is mounted on a copper sleeve 4 by a molybdenum foil 5, the sleeve 4 sliding within a copper cylinder 3. The tube is inverted so that the cathode falls into contact with the anode 12, and after the tube has been raised to the required temperature the tin ring 13 is heated by high frequency currents to solder the sleeve 4 to the cylinder 3. When the tube cools to its operating temperature a small predetermined spacing between anode and cathode is obtained which may be of the order of 5Á. The method may also be applied to the manufacture of triodes.

Title: Method for the selective recovery of organic materials from liquids
Filed: 1920-07-07
Abstract: Liquid containing organic matter is subjected to the action of gas bubbles and the matter to which the gas adheres is separated by flotation; other matters are then removed by successive treatment with flotation agents and gas.  Insoluble soap and oil are mentioned as suitable flotation agents and air and carbon dioxide as suitable gases.  The method is applicable to liquors containing fat, butter, soap, waxes, vegetable or minerals oils, to waste liquors from the treatment of hides, from textile and woolwashing plants and laundries, to silk gum liquors and fullers' liquors.  The liquor may be treated, either before or simultaneously, with the gas treatment, with a precipitating, coagulating or flocculating agent.  The liquor may be agitated during the gas treatment.  The separated organic matter may be dehydrated, for example by filtration under suction, and further treated for the recovery of valuable products.  In the case of waste liquor from tanneries, hair is first separated by gas treatment, then insoluble soap is added to mix with the fleshings and hide particles, the mixture being separated from the liquor by further treatment with gas.

A nuclear fuel element for a fluid-cooled reactor comprises a composite body of fissile material encased in a can having closure means, and is so arranged that, if a leak develops near the closure means, reaction takes place between the coolant and a portion of the fissile material adjacent the closure means, which portion becomes distorted so as to displace the closure means and increase the size of the leak; more radioactivity is thus released and this facilitates detection of the leak. As shown, a tubular fuel member 1 is enclosed in a can 2 with welded end caps 4. The member 1 is closed by a plug 14 of zirconium alloy; the can also contains a ceramic disc 16, a retaining ring 18, and a plug 17 of fissile material. The plug 17 operates at a higher temperature than the member 1, is made porous or laminated so as to have a large surface area, and may be more reactive chemically than member 1, being made for example of uranium carbide or a uranium-silicon alloy. The plug 17 may be thermally insulated from the member 1. In other arrangements, the member 1 is in the form of a solid rod and the member 1 and the plug 17 are of the same material.
