A magnetic electron lens assembly for correcting asymmetrical leakage fluxes between two lenses, e.g. in an objective lens and an intermediate lens or within a yoke of a single lens, comprises in the former case an annular member of magnetic material 16 acting as a flux guide, rigidly fixed to one lens 18 therewith forming a large symmetrical magnetic gap S 5 , and forming a smaller, asymmetrical magnetic gap S 4  with the other lens. The magnetomotive force associated with the leakage flux in the large gap S 5  is large but symmetrical, whilst the asymmetrical magnetomotive force associated with the small gap S 4  is small, the magnetomotive force being a function of the gap spacing. A flux guide within the yoke of a single lens, Fig. 7 (not shown), has two cylindrical magnetic members extending in the direction of the electron beam and having between them a short cylinder of non-magnetic material which forms a large, symmetrical gap, a small asymmetrical gap being formed between the cylindrical end surface of one of the magnetic members in the cylindrical inner surface of a yoke member.

Abstract: 1,226,285. Solvent recovery in the paint and lacquer industry. HUNTER DOUGLAS INTERNATIONAL Ltd. 19 May, 1969, No. 25436/69. Heading BIB. Organic solvent is recovered from a slurry, containing dyestuffs, pigments and/or synthetic resins, obtained by cleaning painting apparatus with the solvent, by mixing the slurry with an aqueous alkaline solution, e.g. sodium hydroxide solution, and subjecting the mixture to distillation by circulating it through vessel 1 and heat-exchanger 7 by means of pump 5. The vapours pass from vessel 1 to watercooled condenser 9, and a mixture of organic solvent and water is obtained as distillate. The initial slurry is preferably mixed with at least an equal amount of 1 % aqueous alkaline solution. After about 95% of the solvent has been distilled off, valve 12 is closed and valve 13 is opened so that the residue in vessel 1 may be flushed out with water supplied through pipe 14. Valves are also provided so that the heat-exchanger can be cleaned with water.

Title: Process for the production of carbides
IPC: C01B31/30
Filed: 1952-10-10
Abstract: Carbides of tungsten, molybdenum, vanadium, titanium, tantalum, niobium, chromium and boron are produced by adding an oxidic ore thereof to a melt of calcium carbide, and adding sufficient free carbon before or during the operation to maintain a proportion of free carbon and a total of free and combined carbon in excess of that necessary to reduce the oxide and form the carbide of the element concerned, and thereafter separating the desired carbide from the reaction mass, preferably by decomposing the reaction mass with water or steam.  The carbides are then separated from the resulting lime sludge.  Finer grain carbides result from the addition of less than 1 per cent. (based on the element to be carburized) of vanadium, aluminium or cerium mixed metal to the melt.  The ores employed may have been previously roasted, concentrated or dressed mechanically or magnetically.

Filed: 1924-10-29
Abstract: 238,743. Penrose & Co., Ltd., A. W., and Owen, M. Oct. 29, 1924. Inking-apparatus.-The ink is removed from the surface of the engraved cylinder of an intaglio printing-machine, by two scrapers 29, 21, the first of which is of relatively soft material, such as celluloid, and removes the bulk of the ink, and the second of which removes the ink from the raised parts of the cylinder in the usual way. Either of the scrapers may be inclined to the axis of the cylinder so as to give a slight transverse movement to the ink. The scraping- devices are carried on a frame 3 pivoted on the shaft 2 of the engraved roller 1. To a rectangular bar 26 fixed in the frame is adjustably secured a bar 27 to which is attached the celluloid scraper blade 29. Lugs 38 attached to the bar 26 carry screws 34, 35 loosely connected to the bar 27 and to a plate 30 respectively. A stiffener plate 22, to which the main scraper blade 21 of thin steel is secured by a clamp 20, is attached to the plate 30. Packing-pieces 32, 33 are placed between the parts 26, 30 to give the scraper blade the required inclination to the cylinder axis. The consequent adjustment to move one end of the scraper forward relatively to the other end due to this inclination is obtained by the screws 34 and by making the stiffener plate 22 wider at one end than at the other. Pressure is applied to the scraper 21 along the line of the clamp 20 by a roller 18 adjustably carried by brackets 17 on a bar 14 rotatably mounted in the frame 3, a spring 23 adjusted by a nut 37 being connected to an arm 24 on the bar and to the machine frame. Where an engraved sheet is secured on the cylinder 1, the roller 18 is lifted off the scraper 21 as the cylinder gap passes underneath the scraper, by a cam 9 on the shaft 2 actuating a slide 5 on the frame 3 carrying a pin 6 engaging a pivoted bracket 10, one arm 11 of which bears against an arm 13 fixed on the bar 14. Specification 235,614 is referred to.

Abstract: 1,084,547. Gas chromatography and gas/ solid adsorption. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 23, 1964 [July 1, 1963], No. 26021/63. Heading B1L. In a counter-current gas chromatography or gas-solid adsorption apparatus, a downwardly moving bed with adsorbed material is continuously transferred from the bottom of one column (comprising the upper part of tube 1) to an intermediate point 4 in another column (comprising tube 3 and the lower part of tube 1). Beds of solid adsorbent or liquid-impregnated inert solids move continuously down tubes 1, 3, upward flow purge gas enters at 11 and mixture for separation enters at 8. Components of the mixture are removed at 9, 10 and a further component, stripped from the bed by heater 12, at 13. The process is controlled by heating or cooling the tubes, varying the bed feed in column 3 by rotary valve 5 and varying the purge gas flow. Solids leave column 1 on to turntable 6, are removed by scraper 7 and returned to hopper 2. In the example, nitrogen purge gas and a bed of granular firebrick, impregnated with polyoxyethylene 400 diricinoleate, separate a mixture of benzene, cyclohexane and methylcyclohexane (flow rates &c. given). A number of columns, each discharging into the mid-point of the next may be used in series.
