Title: Improvements in or relating to the handling of carbonaceous solids in the heat treatment thereof
IPC: B01J8/38
Filed: 1950-06-15
Abstract: 672,477. Carbonization or gasification of solid carbonaceous materials. STANDARD OIL DEVELOPMENT CO. June 15, 1950 [June 20, 1949], No. 14977/50. Addition to 654,686. Class 55 (i). In a fluidized process for the carbonization or gasification of plasticizing carbonaceous solids, hot non-plasticizing solids are mixed with the solids to be carbonized or gasified, e.g. coal or lignite, in a mixing and pre-heating zone by injecting a stream of the plasticizing solids into a stream of the non-plasticizing solids. The plasticizing solids are fed from a hopper 1 to the nozzle 16 of an injector 15, while non-plasticizing solids consisting of the residue from a heater 40 are also fed to the injector via a line 42, the mixture being injected into an elongated zone 10 and finally passing into a carbonization or gasification zone 20. The injector nozzle 16 is jacketed and a cooling liquid circulated therethrough. The weight ratio between non- plasticizing and plasticizing solids is at least 4 to 1 and temperatures are maintained of 900-1200‹ F. in the heater and 800-1000‹ F. and 1300-1700‹ F. in the zone 20 for carbonization and gasification respectively, partial combustion of the solids in the zone 20 being used, if necessary, to keep the desired reaction temperature. Gaseous products from the zone 20 are withdrawn through the line 25 and solid residue not circulated for combustion in the heater 40 is rejected from the system through the line 31. A waste-heat boiler 49 may be provided in the line 47 to recover heat from the flue gases leaving the heater 40. In a modification the heater 40 is omitted, partial combustion of the solids in the zone 20 supplying all the heat required for the process and hot residue from the zone 20 is fed as the non- plasticizing solid to the injector 15.

Title: A device for generating alternating or pulsating current of constant frequency
IPC: H02S99/00
Filed: 1935-05-23
Abstract: 455,441. Converting ; automatic control systems. SPEIGHT, E. A., 39, Braemar Avenue, Wimbledon Park, and RADLEY, W. G., 49, Blackheath Park, both in London. May 23, 1935, Nos. 15013 and 15016. [Classes 38 (ii) and 38 (iv)] Wave-form.-Apparatus for generating alternating or pulsating current of constant frequency comprises a pendulum which cooperates with a photo-electric cell and a beam of light. The amplitude of swing of the pendulum is maintained constant. On the pendulum is mounted a mask having a shape shown in Fig. 1 to produce a sinusoidal wave form or the mask may have any other shape depending upon the wave form desired. A narrow beam of light is projected from a light source through the mask on to a photoelectric cell from which the output is taken. Alternatively reflected light may be used as by the use of a mirror or the shutter may operate on the " variable area " or " variable density " principles known in sound recording. The amplitude of swing of the pendulum, and hence the wave-form of the generated current is maintained constant by examining the output wave-form in a circuit, Fig. 5, and applying the resultant variations to a circuit, Fig. 6, controlling the application of impulses for maintaining the pendulum in oscillation. The output current is applied to a transformer 1 the secondary of which is centre tapped and the circuit of each half thereof is completed through a rectifier 5, or 7 and a condenser 6 or 8. The arrangement is such that when the wave form is symmetrical the condensers 8, 9 are equally charged with their terminals 9, 10 positioned so that the resultant p.d. across the terminals 9, 10 is zero. If the amplitude of the pendulum is too great or too small the resultant potential of the terminal 9, becomes positive or negative with respect to that of the terminal 10. This p.d. is applied through a smoothing circuit across a resistance 14 which is included in series with a biassing battery 28 in the grid circuit of a gas discharge valve 27. The valve 27 is further controlled by current from a photo-cell 19 which is illuminated once in each period of the pendulum by a narrow beam of light which is controlled by a shutter 17 on the pendulum 18. The arrangement is such that with no p.d. developed across the resistance 14 the impulse from the photo-cell is just insufficient to overcome the bias of the battery 28 so that no discharge takes place through the valve 27. The valve 27 discharges a condenser 32 through the coils of an electromagnet 30 driving the pendulum only when the amplitude of swing is less than that desired. If the swing is too great energizing impulses are merely withheld. The condenser 32 is in a relaxation oscillation circuit 34, 33 the periodicity of which is of the same order as that of the pendulum.

Abstract: 1292105 Fluid regulation CORNING GLASS WORKS 1 April 1970 [3 April 1969] 15341/70 Heading G3H [Also in Division G4] Pure fluid proportional amplifier, comprises a supply passage 16, two outlet passages 26 and 28, two entrainment passages 32 and 34 each of which is open to atmosphere at 46 and 48, respectively, and two control passages 38 and 40. In the absence of flow in the control passages 38 and 40, the supply is divided equally between the two outlet passages, such supply serving also to entrain fluid from the passages 32 and 34. Upon a signal being applied to, say, control passage 40, as indicated by arrow 50, such signal acts in opposition to the entrained fluid 36 in passage 34 and so creates a low-pressure zone A in consequence of which the supply fluid is directed in a greater proportion to the outlet passage 28. Conversely, a signal in passage 38 causes the supply to be directed into passage 26. In modifications, Figs.3 to 6 (not shown), the amplifier can be made to operate as a digital device or as a OR/NOR gate.

Abstract: 1,268,263. Drying apparatus. I.F.C. CORP. 24 March, 1969, No. 15382/69. Heading F4G. A method of vacuum dehydration comprises the steps of, placing the material to be treated in a carrier between electrically conductive plates; sealing the loaded carrier in a chamber of dielectric material; reducing the pressure therein; heating the plates by induction heating. In the preferred embodiment the carrier is a series of vertical, spaced aluminium plates (35), the floor of the carrier being formed by spacers (38), Fig. 5, not shown. The plates may be either square with the corners removed (Fig. 7, not shown) to receive cakes of solid material, e.g. fish, meat, or round with a segment removed at the top (Fig. 6, not shown) to receive pre-frozen liquid or powdered material, e.g. coffee. Such material is loaded into the carrier by rams (52), Fig. 9, not shown, whereas the cakes of solid matter are inserted individually between the plates. The carriers are then loaded into tubes of glass or other insulating material which are then sealed by cover-plates 55. The tubes 10, which may be lined with P.T.F.E. have a single, or two parallel induction windings of insulated copper or aluminium wire or tubing 14 wound thereon. Valve 23 is then opened establishing a vacuum in the tubes 10, shock to the material is prevented by bleeder line and valve 56. The induction heating is then switched on, the apparatus may be operated either at high frequency or mains frequency. For H.F. operation tubing is used for the windings 14 and cooling water is circulated therethrough. The temperature of the material is sensed by thermocouples 17 which control the power supply via switch 19 for H.F. operation or via toroidal voltage regulators for mains frequency operation. During heating the water vapour evolved is drawn off through the vacuum manifold 24 into the condenser 26 where it freezes on the condenser plates. There may be two condensers 26 one of which is in operation while the other is defrosted. At the completion of the predetermined drying cycle valve 23 is closed and valve 25 opened introducing nitrogen or another relatively inert gas at atmospheric pressure into the tubes 10. The cover-plates 55 are removed and the carriers which may be coated with P.T.F.E. are emptied.

[Also in Divisions B1 and G6] Food crops are grown in a shallow pan 86 (Fig. 9e) floating on the sea, the pan being provided with a layer of soil 83 (Fig. 9g) which is irrigated with desalinated water obtained by distillation of sea water which is boiled by heat conducted to it from a rotatable nuclear reactor. Sea water is pumped up through a pipe extending into the sea from the centre of the pan. The sea water flows radially outwards through spaces 65 between base-plate 62 and a heat-transfer plate 63, and while doing so the water is heated by steam, derived from water boiling around the reactor, condensing on the opposite side of plate 63. The warmed sea water flows inwards through tubes 66 and then flows upwards around screw blades mounted on the reactor, thereby maintaining it in rotation. The steam from the boiling water is conveyed to a turbine which actuates the sea-water pump. The steam discharged from the turbine flows into the space between heat-transfer plate 63 and porous plate 82, where the steam is partially or wholly condensed. The condensate, and any residual steam, permeates through plate 82 into the soil above. It is stated that a "floating farm" comprising several interconnected pans of soil, each 1,000 yards square, may be assembled.
