Title: Process for the manufacture of sulphur trioxide
IPC: C01B17/76
Filed: 1941-02-24
Abstract: 571,207. Sulphur trioxide. CATHALA, J. Feb. 24, 1941, No. 2516. [Class 1 (i)] A gas mixture containing at least 15 per cent. of sulphur dioxide and oxygen not in excess is subjected to catalysis under at least 3 atmospheres pressure and the products are cooled to condense a mixture of sulphur trioxide and dioxide, which is separated by fractional distillation. The mixture may be obtained by the evaporation of liquid sulphur dioxide at a controlled temperature into air under pressure. The condensation may be effected in stages, yielding mixtures with successively higher sulphur dioxide content, which are fed into the rectifying column at appropriate places. The sulphur dioxide fraction may be liquefied and recirculated. The exit gases undergo a final purification by washing or adsorption. Specifications 467,298 and 519,570 are referred to.

IPC: G11B7/00
Filed: 1949-01-29
Abstract: 666,332. Optical sound-recording. FERRANTI, Ltd., and TAYLOR, M. K. March 24, 1950. [Jan. 29, 1949] No. 2517/49. Class 40 (ii). [Also in Groups XX and XXXIX] A method of recording from a plurality of sources for subsequent reproduction such as' for producing a stereophonic sound effect in conjunction with a kinematograph, comprises modulating beams of different spectral colours by the different sources and recording the light variations along a track on colour-sensitive photographic material. In the embodiment described, light from sources 1, 2, 3 is modulated by devices 12 controlled by microphones 7, 8, 9. Filters 4, 5, 6 of different colours are placed prior to or following the modulating devices 12, so that modulated light beams of different colours are focussed, by means of an objective lens 17, on to a moving colour film 20. A prism or diffraction grating 16 may be employed for the purpose of projecting the separate beams simultaneously on the same part of the length of the film, in which case reproduction of the separate original signals is effected by dividing the beam from a light source 30 into its component colours by means of a prism or diffraction grating 34, and using the separate beams so . obtained to energize photo-electric cells 36 which are coupled to amplifiers 37 and loud-speakers 41, 42, 43. Variable width or variable density recording may be employed or a combination of both.

Title: Improvements in or relating to cameras
Inventor: WELZEL HERBERT
IPC: G03B19/04
Filed: 1963-01-21
Abstract: 1,016,258. Cameras. PENTACON DRESDEN KAMERA-UND KINOWERKE, VEB. Jan. 21, 1963, No. 2545/63. Heading G2A. In a camera having an electric motor drive for film wind and shutter setting, the drive can also be operated manually by means which can be coupled frictionally to a wheel of the motor drive. The manual arrangement can be used instead of the electric drive when preferred, or when the latter is not functioning properly. In the form shown, the gear wheels 2, 3, 4 form part of the drive from the electric motor, wheel 3 being mounted on a hollow spindle 11. Axially within spindle 11 is a drive shaft 9 having a gear wheel 10 fixed thereto. Spindle 11 can be engaged with shaft 9 by means of a pawl 7 pivoted to it at 6, the pawl engaging a groove 8 in shaft 9. Wheel 10 engages a rack 14 which operates the shutter-setting mechanism, pawl 7 at the same time disengaging from shaft 9, so that spring means can return the rack to its initial position. Wheel 3 also operates the film transport via wheel 4. This carries a disc 15 having a radial cut-out portion 16, and on the disc is loosely mounted a blocking disc 17 having a corresponding cut-out portion. A blocking lever 18 pivotable at 19 has a hooked end which can engage in these cut-out portions. It is pivoted out of engagement initially, and re-engages automatically after one complete rotation of discs 15 and 17, and hence of the film-winding wheel 25. This is spring-loaded, and rotatably mounted on disc 15, but can be uncoupled therefrom by the action of a rod 22, for the purpose of winding back the film. The manual setting means is operated by a stirrupshaped handle 27 which is shown (Fig. 2) in full lines in the manually operable position, and can pivot up and fold away into the non-operable position shown in dashed lines. This handle is connected by hinge pins 28 to a free-wheel coupling 29 (29a, 29b, &c.), which is rotatably mounted on a bolt 30 screwed into spindle 11. Between the coupling and the end of spindle 11 is arranged a friction disc 32 and a domed spring disc 33. Thus by turning the handle 27 a frictional engagement is effected through the free-wheel coupling to the drive wheel 3, and hence wheel 10, which operates the shutter-setting mechanism, and wheel 4, which operates the film-wind. In the modification of Figs. (not shown) 4 and 5, the bolt 30, instead of screwing into the hollow spindle 11, can be pushed into resilient engagement therewith. In the further modification of Figs. (not shown) 6 and 7, the free-wheel coupling is replaced by an alternative form of spring-loaded coupling.

Title: Improvements in and relating to the refining of lead
IPC: C22B13/06
Filed: 1948-01-29
Abstract: A modification of the invention of the parent Specification comprises adding to molten impure lead containing arsenic a sufficient quantity of zinc and selecting a sufficiently high temperature at which the supernatant layer formed removes the arsenic so that the remaining quantity of zinc corresponds to that necessary for removing other impurities, whereby on heating the melt to above the said high temperature and cooling in a number of steps, first to the said high temperature, and removing the supernatant layer formed in each step, the arsenic and other impurities are removed from the zinc.  Copper, gold and silver may thus be removed separately in three steps after removal of arsenic.  Alternatively copper and then gold together with silver, or copper with gold and then silver, may be removed in two steps after removal of arsenic.

Title: A method of removing hydrogen sulphide from gas mixtures containing the same
Inventor: STORP KLAUS
IPC: B01D53/02
Filed: 1965-01-21
Abstract: H2S is removed from gaseous mixtures also containing oxygen and moisture by passing the mixture over active carbon impregnated with iodine whereby the H2S is oxidized to sulphur.  The temperature may be between 30 DEG  and 120 DEG  C.  The iodine content of the active carbon may be between 0.1 and 3.0% by weight.  The entire carbon may have a B.E.T. surface of 1100 m2/g., a most frequent pore radius of 7 to 8 <\>rA and a grain size between 3 and 4 mm.  The process may be performed in two stages over beds of active carbon, the first or both of which may contain the iodine. The active carbon may be impregnated by subliming iodine and allowing the carbon to with a solution of iodine or aqueous potassium iodide.  The impregnated active carbon may be regenerated by extraction of the S with CS2. Organic sulphur compounds may be removed from synthetic gas by initial catalytic hydrogenation then oxidizing the H2S by the above process.

Title: Electrodes for carrying out electro-chemical processes and processes of electrolysis employing the same
IPC: C25B11/12
Filed: 1932-01-30
Abstract: 389,244. Electrolysis. BERL, E., 40, Wilhelmstrasse, Darmstadt, Germany. Jan. 30, 1932, No. 2806. [Class 41.] Electrolytic processes are promoted by the use of anodes and/or cathodes consisting wholly or in part of activated carbon. The invention is particularly applicable to the production of hydrogen peroxide by cathodic reduction of oxygen, the electrolytic manufacture of perborates and persulphates, and the electrolytic oxidation and reduction of organic and other substances which are only slightly soluble in the electrolyte. The electrode may be in the form of a pipe activated on the outside, to the inside of which a reacting gas is supplied. The interior of the pipe may be filled with porous material such as carbon. Alternatively the upper end of the electrode may project into a gas chamber. The processes may be carried out at atmospheric pressure or at higher or lower pressures. The activation of the electrodes may be effected by impregnating them with the potassium salts of the soluble acid tars produced in the purification of petroleum or coal tar fractions with sulphuric acid, and heating. The electrodes may be provided with insertions of higher conductivity such as graphite or metal gauze or the active carbon may be packed in a grid of such material The electrodes may be impregnated with catalysts which promote the desired reaction or which inhibit detrimental decomposition reactions. Examples of the latter class are #-nitroso naphthol for use in alkaline solutions, and salicylic acid for use in acid solutions. The electrodes may be coated with an extremely thin layer of a water-repellent substance such as paraffin. In an example, oxygen is led through a tubular activated cathode into a cell without a diaphragm containing a solution of sodium borate ; the anode being of platinum and having a surface one-third that of the cathode. At a voltage of 10 and temperature of 5‹ C. solid perborate separates on both electrodes. The process can also be operated with a diaphragm with sodium borate as the anolyte and sodium carbonate or bicarbonate as the catholyte or vice versa.

Filed: 1922-02-02
Abstract: 188,597. Jack, A., Burness, J. Y., and Jack & Co., Ltd., A. Feb. 2, 1922. Winches; driving-gear; apparatus with jointlycontrollable drums.-The opening drum A for operating a double-chain grab is connected to its shaft B by means of a spring E, the shaft being geared by equal spur wheels C to the hoisting drum D. During the operation of winding in the hoisting-rope to close the grab, the drum A remains stationary and the spring E is tensioned. When the closed grab is raised from the ground the spring has been tensioned sufficiently to drive the drum A to take up the slack in the opening rope. To open the grab a brake P is applied to the drum A and the hoisting-drum is paid out. This operation first uncoils and then re-coils the spring E, the unloaded grab then being lowered under the control of the brake P and the energy of the re-coiled spring acting to drive the winding drum to pay out at the corresponding rate. To prevent overstrain of the spring, a travelling nut H engages claws L on the drum at the limits of tension, and effects a positive drive.
