Title: Improvements in ionisation manometer tubes
IPC: H01J41/04
Filed: 1947-11-19
Abstract: 669,631. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. (Standard Telephones & Cables Pty., Ltd.). Nov. 19, 1947, No. 30696/47. Class 39 (i). An ionization manometer tube comprises, in an envelope 21 provided with an opening 22 adapted to be connected to the source of gas whose pressure is to be measured, an M-shaped filamentary cathode 11, located outside of and parallel to one of the sides of a box-shaped grid 4, secured as by welding to support wires 5 and 6, and surrounding a collector electrode 8 made from thin nickel strip or suitably dimensioned wire, secured as by welding to support wires 9 and 10, which together with a wire 20 connect the collector electrode 8 to a sheet-metal reflector electrode 19, which is substantially parallel to the grid, and preferably concave, as shown. The reflector electrode 19 may be omitted, but is desirable to prevent the possibility of cracking of the glass envelope 21 due to local heating under conditions of bombardment obtained when working with comparatively high gas pressures. The upper portions of filament 11 are supported by wires 15 and 16 and springs 17 and 18, and the lower intermediate portion by a wire 14, the ends being connected to support wires 12 and 13. The separation of the support wires 5 and 6 for the high potential grid 4 from the leads 9 and 10 to the collector electrode 8 by the low potential filament leads 12 and 13 provides a slight " guard ring " protection against leakage currents, which may be further reduced by providing support wires 9 and 10 with glass sleeves 35, 36 and 37. Small baffle-plates (not shown) may be mounted on wires 9 and 10 above sleeves 35 and 36 to prevent deposition thereon of metal evaporated from the hot electrodes. Degassing of the electrodes before operation of the tube is effected by connecting the grid 4, collector electrode 8, and reflector electrode 19, if provided, together and to the positive terminal of a supply source whose negative terminal is connected to the filament. The filament is suitably energized, and the electrodes are made red-hot by the electron current impinging thereon. Conventional voltage supply arrangements are provided in the form of transformer 24 for the filament, negative battery 29 for the collector, and positive battery 34 for the grid, the filament supply being interrupted by contacts 27 of relay 28 in the grid circuit when the current passing to the grid exceeds a predetermined value, thus keeping the filament at substantially constant temperature. In a simplified construction, the collector electrode 8 is omitted and two sets of three adjacent grid wires on the side nearest the reflector 19 are cut away to provide openings so that the positive ions are collected by the electrode 19.

Title: Improvements in the purification of crude benzole
IPC: C07C7/05
Filed: 1961-08-25
Abstract: Crude benzole is purified and benzole is simultaneously recovered from a coke oven gas by mixing the crude benzole with the hot coke oven gas and fractionally condensing the benzole hydrocarbons by cooling in stages.  The crude benzole may be one obtained by washing coke oven gas and recovering from the wash oil. The gas used in the purification is heated by compression and preferably saturated or more than saturated with crude benzole, some of the purified benzole being recycled if necessary to to effect this.  The impurities are recovered first during the condensation and part of this fraction may be recycled and the gas containing light oil is then preferably desulphurized before condensing out benzene, toluene, xylene and accompanying aliphatics.  The remaining gas is preferably washed with an oil to recover remaining benzole and then dried by cooling; the cooled gas is then used to cool the gas in the condensations by heat exchange.  The crude benzole may be added to the gas by injection or by contact in a washer, e.g. containing bubble trays.

Patent GB-416209-A (GB)
Title: Apparatus for and methods of removing suspended particles from blast furnace gases
IPC: B03C3/53
Filed: 1933-11-14
Abstract: <PICT:0416209/III/1> In a process for the removal of suspended particles from blast furnace gases, at temperatures of approximately 250 DEG  F., the gases are passed through an electrical precipitator over the collecting electrodes of which is flowed a carrier liquid having a vapour pressure less than 40 mm.  Hg at 250 DEG  F., and at least a portion of the suspended particles are separated from the carrier liquid, which is then returned to the collecting electrodes. Suitable carrier liquids include petroleum distillates, e.g. drained crank case oil, or organic compounds such as diphenyl. The use of such a liquid is stated to avoid the necessity of cooling the gases, and by circulating the liquid at approximately the temperature of the gases treated, the sensible heat of the gases is conserved when subsequently used, e.g. for burning. According to the arrangement shown, gases from an iron blast furnace 1 are passed via a settler 3 to a centrifugal separator 5 which is used with gases of high dust content.  The gases then pass upwardly through collecting electrodes 9 in an electrical precipitator 8 and the clean gases leave through flue 10.  The flushing liquid is supplied, preferably at the temperature of the gases, by pipe 15 and is divided into several streams by control box 22 and is carried by separate pipes 24 to flood various areas of the top header and the inner surfaces of collecting electrodes 9.  The suspended matter is carried by the liquid into sump 11 which is divided by baffle 12.  Relatively clean liquid rises in the annular compartment and is drawn off by pipe 13 for reuse.  A portion, e.g. from 10--20 per cent of the liquid reaching sump 11 is drawn off through pipe 14, filtered and added to the liquid to be recirculated through the precipitator.  The solid material in the filter 18 may be returned to the blast furnace.  The apparatus is preferably heat insulated and the flushing liquid may be passed through a heat exchanger if necessary before flushing the electrodes.  In the case of gases at very high temperatures, e.g. from ferro-manganese furnaces at about 900 DEG  F., and very low in water vapour, the temperature of the gases may be lowered by indirect air cooling and direct water cooling to about 300 DEG  F. for use in the above process without acquiring an excessive water content. Reference has been directed by the Comptroller to Specification 118,334, [Class 1 (i)].
