Title: Process for cracking heavy hydrocarbons
IPC: C01B3/42
Filed: 1974-04-16
Abstract: 1460615 Cracking OSAKA GAS CO Ltd 16 April 1974 [18 April 1973] 16687/74 Heading C5E Heavy hydrocarbons are cracked in a fluidized bed of granular solid particles in a reactor by supplying a gas containing at least 5% of hydrogen to the bottom of the reactor at a temperature of at least 500‹ C., supplying heavy hydrocarbons and granular solid to the top of the reactor to maintain the temperature there not above 550‹ C., and drawing off cracked gas and vapours from the top and granular solid and coke deposited from the bottom. Preferably the granular solid is coke, but alumina, silica or zirconia can also be used. As shown, heavy hydrocarbons, granular solid and hydrogen are supplied by lines 1, 2 and 3 to reactor R 1 . Cracked gas and vapours are taken off by line 4, cooled at A and separated into gas and liquid phases at B. The separated gas may be taken off by line 6 or recycled by line 12; the liquid is taken off by line 7, or part of it may be recycled by pump P and line 8 as a further control of temperature. The granular solid with coke deposited on it is taken off by line 9 to a second reactor R 2 , to which are supplied steam and oxygen by lines 21 and 22 to burn off coke. Decoked solids can be taken off by line 34 or recycled by line 33. Gas from the regenerator (mainly CO and H 2 ) is taken off by line 23 and scrubbed at D, the slurried coke from the scrubber being recycled by line 25. The scrubbed gas is taken by line 27 to a converter F where CO is oxidized to CO 2  and then by line 28 to tower G, where CO 2  and H 2 S are absorbed. The gas is now mainly hydrogen and may be taken off by lines 29 and 31, or taken through compressor C and heater H to provide the hydrogen needed in reactor R 1 . The oil in line 7 can be further hydrocracked or hydrodesulphurized, using hydrogen from the line 31. The heavy oil to be cracked may be a crude or residual oil. The hydrogen may be substantially pure or mixed with methane, ethane, ethylene, steam or CO 2 .

Title: A New Improved Machine having a Guard
Inventor: MILLER GEORGE ERNEST
IPC: F16P3/16
Filed: 1965-04-21
Abstract: 1,151,693. Machinery guards. SMC STERLING Ltd. 21 July, 1966 [21 April, 19651, No. 16788/65. Heading F2J. In a guard system for a machine such as a press, including a transparent U-shaped guard 6 hung by pins 6a in slots 6b on a vertically slidable frame 4-3-5 supported and moved by a double-acting pneumatic jack 8, if the guard is impeded while being moved into its protective position in advance of the press ram working stroke, the resulting movement of the guard relative to the frame member 4 actuates micro-switches 10 to stop the machine and return the guard to its " open " position. The rods 3 of the frame slide in fixed tubular guides 2. Compressed air is supplied to one or other end of the jack 8 under the control of a solenoid valve (22) (Fig. 3, not shown) and a solenoid valve (20) controls the supply of compressed air to a clutch-operating cylinder (21) of the machine. When the solenoid (29) of the valve (22) is energized, air is admitted to the jack 8 to raise the guard. A cam on a moving part of the press acts to de-energize the solenoid (29) to allow the guard to descend in advance of the press ram, and re-energizes the solenoid to raise the guard at the end of the working stroke, the operating cycle continuing so long as a foot switch (27) (Figs. 2, 4, not shown) is closed. Micro-switches 10 are in series with the foot switch (27). A pressure switch 16 in the pneumatic system opens to cut off the electric supply when the air pressure is below a predetermined value.

Title: Method of recording, analysing, converting or utilising local or time distributions or successions of energy
IPC: G11B7/00
Filed: 1930-05-30
Abstract: 360,820. Recording and reproducing sound, pictures, &c. MœLLER, C., 86, Soorstrasse, Charlottenburg, Berlin. May 30, 1930, No. 16799. Convention date, May 30, 1929. Addition to 279,909, [Class 40 (ii), Phonographs &c.]. [Class 40 (ii).] In the translating, converting or recording of successive energy forms by the process described in the parent Specification, wherein the blurring effect of scanning devices having a finite width is corrected by the superposition at every point of a correction obtained by scanning portions adjacent to the point so that an energy form correctly representing the original form results, the resulting energy form or record is, according to the present invention, over corrected so as to compensate for the blurring effect of the scanning or equivalent device employed in translating or reproducing the energy form. The method is applicable in making or copying optical sound records and in television, enabling wider slits or scanning devices to be used whilst correcting for the distortion or blurring effects introduced thereby, and is also applicable in the production of magnetic records to compensate for the finite width of the magnet poles. In making optical sound records from an energy sequence representing the sound, each part of the sequence when being recorded is distorted or over-corrected, to such an extent as to give correct reproduction by the usual reproducing apparatus, by the superposition on that part of the effect of the immediately adjacent parts of the sequence by means of an optical system of prisms &c. In applying the method to the production of an over-corrected variable width record by photographic printing form a correct record, the over-correction obtained from the immediately adjacent parts may be printed on the edge of the record strip opposite to that from which the main record extends and these may be applied collectively in one tone or in different colours to produce varying effects in the over-corrected combination. Fig. 3 shows the correction b applied to a record c produced by a wide slit 2 whereby the record is over-corrected to the extent necessary to overcome the distortion produced by the finite slit and other factors in reproduction. Fig. 5 shows the corrections due to the application separately of corrections imposed by adjacent parts of the record, the separate corrections b- and b+ to the record B being applied if desired in different colours. The method enables shorter magnetic sound records to be reproduced, and permits picture transmission on smaller frequency bands and with greater contrasts. Specification 331,809, [Class 40 (ii), Phonographs &c.], is referred to.
