Title: Improvements in magnetic apparatus for measuring the thickness of thin layers
IPC: G01B5/06
Filed: 1940-07-01
Abstract: 542,968. Magnetic tests. TAIT, W. H., and CHALMERS, B. July 1, 1940, No. 11119. [Class 37] Magnetic apparatus for measuring the thickness of thin coatings, such as tin, chromium, paint, or lacquer, on magnetic bases comprises a magnet adapted to be attracted to the base, a standard non-magnetic layer adapted to be inserted between the magnet and the coated base, and means for measuring the force required to detach the magnet both with and without the layer. The latter should be about 100 times as thick as the coating to be measured, and is arranged as a bronze layer over one pole 1 b of a magnet 1 which is mounted to rotate about the axis of a counter-weighted beam 2 so as to bring either the pole 1b or the uncoated pole 1a against the magnetic base. The beam 2 can swing on bearings 3 and carries a leafspring 5 engageable by a pin 7a on a pivoted lever 7 which carries a toothed segment 9 engaging a pinion 10 on a shaft 11 carrying an indicator drum 13 and ratchet wheel 12. The lever 7 is engageable by a pin 6 on a rod of a spring-dashpot 8, the arrangement being that by depressing the rod, where it is held by the pawl 15 engaging wheel 12 and depressing magnet 1 so as to free the latter and engage the base with pole 1b, the dashpot spring slowly rotates lever 7 and strains the spring 5 until the magnet is torn off the base. At this point the pawl 15 arrests wheel 12 again and an indication is given on the drum 13. The latter is rotated by mean of a friction brake 16 to zero or other given mark, magnet 1 is rotated, and the above operation repeated with the pole 1a. In this operation an eccentric 18 engages and tensions a spring 17 which assists in providing the greater force necessary. The drum-reading is then a measure of the coating thickness.

Title: Improvements in velocity modulated electron discharge tubes
IPC: H01J25/24
Filed: 1942-08-14
Abstract: 582,240. Velocity-modulated tubes. BRITISH THOMSON-HOUSTON CO., Ltd., MILNER, C. J., and SCOTT, W. J. Aug. 14, 1942, No. 11445. [Class 39 (i)] [Also in Group XXII] In the manufacture of a velocity-modulated discharge tube of the kind in which an electron beam is projected through grids covering apertures in a cavity resonator, distortion of the grids is minimized by giving them their final shape by means of a die after the resonator has been assembled and prior only to the attachment of the resonator to the glass tubes or stems which support the remaining electrodes of the discharge tube and to its final evacuation. In the construction shown the resonator is formed by a groove 1 in a heavy copper annular disc 2 to which is attached a resilient annular diaphragm 3. The disc 2 has a skirt 4 which, after shaping of grids 6 positioned across the central openings of the disc and diaphragm, is sealed to a glass stem supporting an electron gun. A skirt 5 mounted on the diaphragm may be similarly sealed to a stem supporting an electron collecting or reflecting electrode. Shaping of the grids is effected by pressing together dies 8, 9 having suitably shaped operating faces and located as shown, the die 8 being positioned by a sleeve 7 inserted within the skirt 4. The final setting of the gap between the grids is effected by nuts 11 which engage a ring 12 secured to the skirt 5. The attachment of the grids to the resonator may be effected during the shaping operation by exerting sufficient pressure between the dies to cause the grid wires to embed into the walls of the resonator.

Title: A process for the production of aluminium oxide and other aluminium compounds
IPC: C01F7/40
Filed: 1927-05-02
Abstract: 295,227. Haglund, T. R. May 2, 1927. Aluminium oxide and sulphate. - Aluminium sulphidiferous material is first treated to convert the aluminium sulphide into oxide under such conditions that sulphide impurities are left substantially unaffected and then these impurities are removed by treatment of the mass with chlorine or chlorine compounds or mixtures thereof, or with chlorides, sulphates and nitrates or other salts of such metals as are precipitated by sulphuretted hydrogen in acid solution, so that sulphides of metals such as iron titanium or calcium are converted into volatile or soluble salts. Before treatment with chlorine, corundum crystals are separated from the decomposition product, and aluminium hydrate is heated to convert it to oxide. The treatment with chlorine hydrogen chloride, sulpho-chlorides, or aluminium chloride preferably proceeds at above 100‹ C. and so that chlorides of iron and titanium are volatilized. Aluminium hydrate during or after the treatment is heated preferably in a neutral or reducing atmosphere to form aluminium oxide with low solubilitv in acids. Part of the hydrate obtained is converted into chloride and is heated in a moist atmosphere whereby aluminium hydrate is formed and sulphides of impurities are converted to chlorides. Chlorine is used as a gas, liquefied, under pressure or in solution or dry, and chlorides formed may be dissolved out with water. The products during treatment may be stirred in water, and a reducing substance such as hydrogen sulphide or aluminium sulphide added to prevent precipitation of basic iron salts. If the decomposition product is alkaline it is neutralized before treatment with chlorine, and on treating it in water with chlorides, sulphates or nitrates of metals such copper, lead, arsenic, antimony or tin which are precipitated by hydrogen sulphide in acid solution, sulphides of these metals are precipitated, and metallic impurities dissolved and filtered off. The aluminium hydroxide is then dissolved in an acid, such as sulphuric acid. The decomposition product may be subjected to magnetic separation. Specification 232,549 is referred to.
