Title: Improvements in or relating to photo-electric exposure meters
IPC: G01J1/42
Filed: 1952-07-11
Abstract: 721,842. Photographic exposure meters. GOSSEN & CO. GES., P. July 11, 1952 [July 11, 1951], No. 17543/52. Class 98 (1). [Also in Group XL (b)] A photo-electric exposure meter is enabled to measure both direct and reflected light by means of an opal front screen which is slidable between guide rails on the casing of the exposure meter and which may be positioned in front of the light admission aperture of the photo-cell. As shown, light passing through an aperture at the top on the casing is received by a photoelectric cell 5. A number of honeycomb elements 14 increase the effective reception angle of the cell. The photo-cell feeds a moving coil meter 3 the pointer of which moves over a slotted plate 6 below which is a " follow-up " drum 9. This drum is rotated by a knob 11 until one of a number of helically arranged marks 9a on its surface which appear successively beneath the slot in the plate coincide with the pointer. This drum is geared to a record drum 10 a portion of the surface of which is viewed through a second slot 8. The drums bear a series of "f" numbers which may be read in conjunction with the appropriate shutter speeds marked along the slot. The " following " of drum 9 by drum 10 may be effected by a self-starting device instead of manually and a cam 12 on the end of the shaft of drum 9 may close contacts to effect electrical range changing. The two drums may be rotated independently on each other by means of a slipping clutch mechanism incorporated between knob 11 and the shaft of drum 9. This mechanism consists of a plate coupled to the shaft and recessed into the end of knob 11 to which it is coupled by a leaf-spring. In Fig. 3 (not shown), a modification is shown in which the uneven scale of the pointer is joined by channel lines to an evenly divided drum, a follow-up pointer of known type sweeping the ends of the channel lines and simultaneously adjusting drum 10. Drum 9 may be a transparent substance over the surface of drum 10. The screen mechanism (Fig. 18) is in the form of a roller blind 26 sliding in guide strips and rails 28 at opposite ends of the exposure meter. The strip is moved into such a position as to cover the light aperture when a direct source measurement is to be made. This reduces the light reaching the cell to one quarter. The screen 26 may be so arranged as to cover both the light aperture and the instrument window for transport. In this case an opaque substance is positioned over the light aperture of the cell. The screen (Fig. 11) preferably consists of thermoplastic material such as a polyamide or polyurethane known under the Trade Names of " Igamid " or " Ultramid." The screen may be used to provide an extra means of adjustment, for example, by partly closing the cell aperture or the shutter may be so made as to have a varying opacity along its length by altering the height and distribution of the members 27 or by making the base 26<SP>11</SP> of varying thickness.

Abstract: 1,122,074. Centrifugal separators. KG. H. EJEFORS. 21 April, 1966 [22 April, 1965], No. 17547/66. Heading B2P. In the treatment of sludge from industrial and municipal sewage purification plants, the sludge is passed successively through first and second screenless mechanical centrifugal separators so as to separate from the liquid, firstly, the larger and heavier particles and, secondly, the smaller and lighter particles and micro-organisms. As shown in Figs. 1 and 2 untreated sludge is fed via a conduit 2, an inlet 3 and a central conduit 3' into a centrifuge 1 of the screw-conveyor type from which the heavier and larger separated particles are discharged by means of the screw-conveyor through ports 37 and an outlet 6 and the partially clarified liquid containing the lighter and smaller particles and the micro-organisms overflows over the edge of annular regulating washers 35 and is thrown out peripherally and caught in an outlet 5. From the outlet 5 the partially clarified liquid passes into a centrifugal separator 8 of the plate-type from which the clarified liquid is discharged via a conduit 10 and the separated lighter and smaller particles and the micro-organisms are automatically and intermittently discharged through regulatable ports and an outlet 11 into a tank 13. The particles and micro-organisms from the tank 13 are pumped by a pump 14 via a conduit 16 and a 3-way valve 16a either directly on to a belt conveyor 15 or back into the separator 1 which they enter through an annular conduit 4' and from which after de-watering they are discharged with the heavier and larger particles via a conduit 18 on to the belt conveyor 15. From the belt conveyor, the separated particles and micro-organisms may be fed into a combined conveying and dewatering screw device 19. The dewatered particles and micro-organisms are then conducted to a slurry truck 31 either directly or via a furnace 30. The sludge water from the screw device 19 is led via a conduit 25, a pump 26 and a conduit 27 to the feed conduit 2. Alternatively the particles and micro-organisms from the belt conveyor do not pass through the screw device 19 and are led to the truck 31 either directly or via the furnace 30. A number of centrifuges 1 and/or separators 8 may be connected in series or parallel.

Title: Process for beneficiating titaniferous ores
IPC: C22B1/08
Filed: 1972-04-18
Abstract: 1393786 Upgrading Ti ores WENDELL E DUNN Inc 18 April 1972 [29 April 1971] 17868/72 Heading C1N A titaniferous ore is upgraded by passing Cl 2  under reducing conditions at temperatures of 900-1100‹ C. through a fluidized bed of the ore containing ore particles of two different particle size fractions, the small sized ore fraction having a particle size distribution in the range of 60 to 95% by weight, - 100 to +200 mesh and containing sufficient titanium dioxide to reset with the iron oxide in the larger sized ore fraction having a particle size distribution in the range of 60 to 90% by weight, - 60 to +100 mesh, whereby the Ti values of the smaller sized ore fraction essentially replace the Fe values in the larger sized fraction, Fe being removed as chlorides. The small size fraction is preferably high silicate (ground, e.g. to - 72 to + 200 BSS) and is mixed with low silicate ore of larger size (e.g. - 60 to + 200 BSS) and with charcoal or coke. Preferably the Ti oxide content of the small size fraction corresponds stoichiometrically to the Fe oxide in the large size fraction, and is converted into TiCl 4  which reacts with the said Fe oxide, whereby the small fraction is consumed and silicate is released as fly ash. A stream may be withdrawn continuously from the bed, divided into magnetic and non- magnetic fractions, the non-magnetic fraction screened, into a large sized fraction and a small sized fraction and the small size fraction returned to the bed mixed with the magnetic fraction plus an appropriate amount of unchlorinated ore. Alternatively, where the ore has a high silicate content, partially chlorinated ore withdrawn from the bed may be screened, magnetically separated and crushed and the magnetic fraction of the crushed ore returned to the bed for further chlorination. Titanium fines resulting from the crushed magnetic portion of the larger sized particles may also be recycled.

Title: System and apparatus for the utilisation of natural thermal energy
IPC: F01K25/04
Filed: 1919-07-17
Abstract: 152,753. Merz, F. July 17, 1919. Solar and natural heat, utilizing.-Consists in utilizing the heat or pressure generated by the dilution of a concentrated solution, the said solution being then re-concentrated, e.g. by the evaporative power of air, heated by the sun ur other natural source of heat, re-diluted, and so on. Fig. 2 shows one form of apparatus for utilizing the heat due to dilution. The concentrated solution is supplied by a pipe 30 to a chamber 28 and flows down the outer surfaces of the pipes 11 which contain a vaporizable liquid. The diluting-liquid is supplied by a pipe 31 to a chamber 29 and flows down the outer surfaces of the pipes 12. By means of a pump 22, air is circulated around the pipes 12 and is then moistened and passed around the pipes 11, giving up its moisture to the solution flowing down them. The solution is thus heated and the liquid in the pipes 11 is vaporized. The vapour drives the turbine 27 and is cooled and condensed while passing through the tubes 12 to the receiver 19 whence it is returned to the tubes 11 by a pump 25. The diluted solution flows by a pipe 32 to the concentrating plant. Fig. 4 shows one form of apparatus for utilizing the pressure caused by the dilution of a concentrated solution through permeable diaphragms separating it from the diluting-liquid. The solution is supplied by a pipe 41 through a non-return valve 51 to chambers 47, and the diluting liquid is supplied by a pipe 44 to chamber 48, separated from the chambers 47 by permeable diaphragms 46. Pressure is thus caused in the chambers 47, and their contents flow through the pipe 45 to a turbine 27. When the pressure falls, the valve 52 automatically cuts out the turbine and allows the diluted solution to flow through the pipe 55 direct to the concentrator. The valve 51 then allows a fresh quantity of solution to pass into the chambers 47. Sea water may be employed as the solution, and after dilution is returned to the sea, and a further quantity of sea water is then utilized.

The sensor may be a television camera but is preferably an ultrasonic transducer. The positioning of the transducer, selection of correct stored signal and outputs are computer controlled. As described, a range gate generator enables a gate connecting the ultrasonic transducer output to an integrator for a predetermined period and after a predetermined delay thus selecting the depth being analyzed. The integrator output is held and converted by a successive approximation A/D converter to a binary digital signal which is stored. A set of readings are taken at the same position, the results are statistically averaged and compared with the previous value for the same position. The results are recorded, but if any significant difference is found, the transducer is automatically moved around to determine the extent of the defect and this is shown on a C.R.T. and may be hand copied.
