A heat recuperator for use particularly with the cupola furnace described in Specification 758,246 [Group XII], comprises a vertical shaft 4 up which hot gases pass, and tubes 6 extending between upper and lower headers 8, 10, the lower ends of the tubes lying in a single circle close to the wall of the shaft while the upper ends of the tubes lie in a bunch with a surrounding space 13 between them and the wall, air to be heated being forced downwardly through the tubes in countercurrent to the heating gases which enter the shaft within the circle of the lower ends of the tubes and pass upwardly through the gaps between the tubes to leave the shaft by way of the space 13 surrounding the upper ends of the tubes. Preferably the tubes are straight and their upper ends are bunched in three concentric circles, the air to be heated flowing to the upper header 8 through a central pipe 12 extending up the shaft. Heated air leaves the lower header through an opening 14 leading to the tuyeres of the furnace.

Title: Installation for recovering electric power, combined with an alumina manufacturing installation
Inventor: CONTI FRANCESCO ETTORE
IPC: C01F7/06
Filed: 1969-05-29
Abstract: 1,248,817. Alumina. F. E. CONTI. 29 May, 1969 [3 June, 1968], No. 27247/69. Heading ClA. [Also in Division F4] An installation for production of electric power with double heat recovery and comprising a partial recovery electric power station combined with a Bayer process alumina plant includes (1) a first heat-exchanger in which feedwater for a steam generator of a turbo-alternator is heated by thermal exchange with a fluid, e.g. water, after the fluid has been passed in heatexchanging relationship with the mass obtained on completion of a hot caustic alkali/bauxite reaction; (2) a second heat-exchanger in which generator feed water is heated by hot water discharged by an evaporating assembly which concentrates the caustic alkali solution. In one embodiment (Fig. 1), bauxite is treated in reactor 10 with NaOH (at least 30 BaumÚ) at 180-230 C. using steam fed in at 13 from the medium pressure stage 22 of the turbo-alternator. Exhausted lye, after separation from red mud, enters evaporator 14 at 15 and issues in concentrated form at 16 for recycling, via line 12, to reactor 10. Condensed steam from evaporator 14 heats feed water to generator 20 by exchange at 29, and then returns to condenser 24 via line 37. A second stream of generator feed water in line 26 is heated in exchanger 28 by fluid circulating in line 35 and coil 34 located in reactor 10. The temperature of the reaction mass is reduced to less than 100 C. by the heat-exchange fluid. The streams of heated feed-water in lines 30, 31 are combined at 32 before entry to generator 20. In a further embodiment (not shown) water reservoirs are provided upstream and downstream of heat exchanger 28, further heat-exchangers in series with exchanger 28 are provided to further preheat the generator feed water by steam drawn from the medium and low pressure stages of the turbo-alternator, and a de-gassing appliance inserted in the generator feed duct feeds steam to a set of heat-exchangers fed by steam drawn from the high and medium pressure stages of the turbo-alternator. Instead of the generator feed stream (from condenser 24) being divided, as in Fig. 1, heat exchangers 28, 29 may be arranged in series so that the feed stream passes through them successively.

Title: Improvements in and relating to machines for coating and winding sheet material
IPC: D21H19/84
Filed: 1921-10-14
Abstract: 190,838. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 14, 1921. Feeding and winding webs.-In a machine for making cylinders, cores, &c., by coating and winding a web of fabric or paper, the web P is drawn from a roll, coated with molten adhesive, and wound upon a mandrel M so that the several layers of material adhere together to form a tube &c., the controls for the several sections of the machine being placed conveniently to enable a single operator to control the machine. Pressure is applied to the mandrel by a lever 53 carrying a weight 55 adapted to be adjusted upon it by a rack and a pinion 56; the lever can be raised to release the mandrel by a handle applied to a shaft 65 that acts through wormgearing 64 upon a chain 58 secured to the lever. Either the mandrel M or the rollers L upon which it bears may be rotated positively through worm-gearing 35 driven by a motor 40. If the mandrel M is so driven, the pinion that immediately rotates it is carried by a lever controlled by compressed fluid so that adjustment can be effected as the diameter of the wound web increases. If the rollers L are driven positively a clutch 34 enables them to be disconnected. Rollers 12 for tensioning the web are adjustable by rotating a worm-wheel 13 by a. handle 15.

Title: Improvements relating to electrical measuring instruments

IPC: G01R27/18
Filed: 1952-12-30
Abstract: 738,172. Electric tests. EVERSHED & VIGNOLES, Ltd. March 26, 1954 [Dec. 30, 1952], No. 27330/52. Class 37. Apparatus for making measurements of earth resistance by measuring the potential drop across two electrodes in the earth and the current flow between them is characterized in that the potential difference is amplified in a high input impedance amplifier so that variations in the resistance of the potential electrodes have negligible effect. As shown (Fig. 3), a 40 p.p.s. voltage is obtained from a handdriven generator AC to feed a current via electrodes C1, C2 through an earth resistance X. The current is determined by measuring the potential difference across a series resistor 4, which is rectified in a synchronous converter 2 coupled to the generator AC, and feeds one coil CC of a ratiometer instrument. The voltage drop across the resistance X is measured by two potential electrodes P1, P2, rectified by synchronous converter 3, partially filtered by resistor R and capacitor C3, reconverted to A.C. by synchronous converter 21, amplified at ACA which has a selective feed-back circuit SFB to remove any A.C. produced by e.g. local power supplies, and fed to the other coil DC of the ratiometer, after rectification at 22. D.C. voltages picked up by the potential electrodes P1, P2 are blocked by series capacitor C. Thus the ratiometer indicates the ratio of voltage to current, i.e. the value of the earth resistance X. In a modification the synchronous converter 21 is removed and a D.C. amplifier is used instead of the A.C. amplifier ACA and rectifier 22.

Title: Gas detection apparatus using radiation detector-s-
IPC: F17C13/12
Filed: 1974-11-04
Abstract: 1475910 Gas analysis and monitoring ATOMIC ENERGY OF CANADA Ltd 4 Nov 1974 [14 Nov 1973] 27476/76 Divided out of 1475909 Heading G1A To monitor gas leaks in a production plant, a collimated beam of radiation is directed from a source to a set of reflectors around the plant, and thence to radiation detectors; the source has a wavelength at which the particular gas to be monitored has an absorption line. In the case of H 2 S monitoring the source is a He Xe laser which operates at the H 2 S 3.6859 Ám line as a result of Zeeman splitting. In Fig. 1 a heavy water plant has H 2 S storage tanks 3 within a fence 5. Various retro-reflectors 4 are mounted on the tanks and are scanned in turn by either the source 2a or 2b. These sources are He-Ne lasers, and also incorporated infra-red detectors. Two more such sources and detectors may monitor the other corners of the plant to give positional information about gas leaks. Source/detector: in Fig. 3 a He Xe laser is modulated and its beam is directed via a small mirror 13 and mirror 14 to the retro-reflectors 4, mirror 14 being angularly displaceable to scan the beam from one reflector 4 to another. The returning beam is somewhat larger than the outgoing one due to beam divergence, and most of it passes around mirror 13 to strike mirror 15, telescope 16, filter 17 and detector 18. The detector output is demodulated at 19 to give a measure of H 2 S absorption. The modulator drive 12 may switch the laser output from one Zeeman state to another, or both Zeeman wavelengths may be emitted at the same time, in which case they are separated at the detector by an etalon or a rotating polarizer plate and one is used as a reference beam. Alternatively the 3.9966 Ám output of the laser can be used as the reference and compared with the Zeeman induced 3.6859 Ám output. Suitable detectors include PbSe, InAs or pyroelectric.
