Title: Process and apparatus for the separation of materials of different specific gravities
IPC: B03B5/34
Filed: 1965-03-04
Abstract: 1,071,928. Centrifugal separators; sink-float separators. UNITEC. March 4, 1965 [March 9, 1964], No. 9340/65. Headings B2H and B2P. Soldis of different specific gravities are separated by placing the solids in a separating medium of intermediate specific gravity, creating a whirl of the solids-medium mixture by means of a pump so as to separate the heavy fraction of solids and the light fraction, and simultaneously discharging the heavy fraction by the same pump which creates the whirl. The solids may be a mixture of a mineral and impurities and the separating medium may be a suspension of magnetite granules of 20 to 300 microns in water. The solidsmedium mixture is introduced axially, radially or, as shown, tangentially through an inlet 1 into a vessel 2 which may be cylindrical or conical with its axis horizontal or vertical. A centrifugal vortex-type pump 6 driven by an electric motor 7, Fig. 2 (not shown), creates the whirl in the vessel 2 and discharges the heavy fraction, separated by centrifugal force, together with some medium through a pipe 8. A suction pipe 10 and an integral diffuser 10a are connected to a similar pump 11 driven by a motor 15 for discharging the light fraction, collecting at the centre of the vessel, together with some medium through a pipe 14. The pump is slidable on a rail 16 to permit horizontal adjustment of the suction pipe 10. The pipes 14 and 8 are connected to recovery systems 21a and 21b respectively, the light and heavy fractions being discharged at 22a and 22b respectively and the recovered separating medium being re-cycled via pipes 20a and 20b connected to a hopper 17 into which the solids to be separated are fed via a spout 19. The pumps 6, 11 preferably rotate in the same direction and in the direction to produce a whirl of the same direction as that produced by the tangential inlet.

Title: Improvements in and relating to luminous electric discharge devices
IPC: H01J61/52
Filed: 1932-01-27
Abstract: 381,609. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and DAVIES, L. J., 147, Murray Road, Rugby. Jan. 27, 1932, No. 9474/31. [Class 39 (i).] Discharge lamps for advertising and beacon lights &c. contain metal vapour such as mercury and one or more gases such as neon in proportion to produce a discharge characteristic of the vapour or gas according to the temperature of the container or part thereof, this temperature being regulated by varying the flow of a cooling medium over the container. A cylindrical container 3 with a graphite anode 4 and an indirectly heated cathode 5 of the vane type is provided with a thinned portion or pip 6 subjected to a jet of cool air flowing through a tube 7 when hot air due to the heat of discharge rises in an outer chimney 2. When a shutter 8 is open, the mercury vapour pressure in the container 3 is low and a red discharge is obtained. When the shutter is closed, the jet of air is stopped and a blue mercury discharge spreads up from the cathode with a clear line of demarcation between the red and blue, until the blue discharge fills the tube. The shutter 8 may be operated manually or automatically under the control of two photo-electric cells sensitive to red and blue respectively and positioned opposite different points of the container 3. Alternatively, the shutter may be operated by a magnet excited partly or wholly by current proportional to the voltage drop across the electrodes-4, 5. In a modification, the container is annular to form an inner chimney with a constriction near the lower end. A flap at the bottom of the chimney controls the flow of air, and the electrodes may be mounted in the annular container or in side chambers.

Abstract: 967,091. Centrifugal compressors. BORSIG A.G. March 13, 1962 [April 14, 1961], No. 9546/62. Heading F1C. In a three-stage radial-flow compressor for gas or air provided with double intermediate cooling and a gearing arrangement having a large central gear-wheel adapted to co-operate with three pinion shafts distributed over the periphery thereof, each of the stages has associated therewith an individual pinion shaft having a compressor rotor mounted overhung on an extension of the shaft and driven at a most favourable speed of the stage concerned, and the compressor housings for the three rotors are cast or flanged on the gearing housing. Three stages 17, 18, 19, Fig. 1, of a compressor are respectively driven at their most favourable speed through pinions 2, 3, 4, of suitable diameters, meshing with a large central gearwheel 1 driven by an electric motor 5 through an intermediate shaft 6 and two couplings 7, 8. The pinions 2, 3, 4 are preferably arranged around the gear-wheel 1 as shown in Fig. 2 with the intermediate pinion 3 above or below the gear-wheel 1. Further, the stages 17, 18, 19 are preferably arranged as shown, but they may be arranged all on one side of the gear-wheel 1 or, any stage may be placed opposite the two others. Interstage coolers 14 and 16 are provided. In an alternative embodiment (not shown), the compressor stages may instead be driven by a steam turbine which may be cast or flanged to the gearing housing and is connected either directly, or through an intermediate shaft and two couplings; to one of the pinion shafts. The pinion shaft chosen is the one associated with the compressor stage whose speed corresponds best with that of the turbine, thereby avoiding the use of additional transmission gearing. It is stated to be known to have a four-stage compressor in which a large central gear-wheel driven by an electric motor drives four pinions each of a size adapted to the rotor of its respective stage. Each rotor disc is driven by a pinion shaft constructed as a torsion rod and is supported at its other side by a pin fixed on or integral with the compressor housing and extending into a central blind bore in the rotor disc. Specification 714,765 is referred to.

Title: Improvements in or relating to methods of making cellular glass
IPC: C03B19/08
Filed: 1946-03-28
Abstract: 622,218. Glass manufacture. PITTSBURGH CORNING CORPORATION. March 28, 1946, No. 9620. Convention date, March 31, 1945. [Class 56] In a process of making cellular glass bodies by sintering a mixture of pulverized glass and a powdered gassing agent as described, e.g. in Specification 447,805, the mixture is heated first to a sintering temperature at which the gassing agent is inactive, then to a higher gassing temperature still insufficient to cause complete fusion of the glass; the bloated body is then cooled and annealed. By thus delaying the gassing till after the glass has cohered a regular cell structure is obtained. To avoid shrinkage during cooling, cellulation in the outer shell of the body may be arrested by rapid cooling while interior cellulation continues, e.g. maintained by the addition of arsenious or antimony trioxide to the mixture before heating, and to prevent dishing, the outer shell may be set hard by external chilling before the annealing stage. The mixture, e.g. prepared by adding the gassing agent to the glass prior to or during grinding, may be charged to a depth of 1 inch into a refractory steel mould coated with hydrated alumina, and passed through a roller hearth furnace according to a specified sintering, gassing and cooling temperature/time schedule (for other chargethicknesses, the time schedule is varied according to the square of the ratio of the charge thickness to 1 inch); the cellulated body, about 6 inches thick, may be removed from the mould before chilling and annealing. A carbonaceous gassing agent, e.g. lamp or carbon black, may be used with a glass containing active oxygen, e.g. SO 3;  the following batch ranges for the latter are given (parts by weight) : sand, 50-60; soda ash or potassium carbonate, 15-22; lime or dolomitic limestone, 12-20; feldspar, 9-16; salt cake, 3-8. The product comprises a heat-insulating vermin- and water-proof buoyant glass block. The Specification as open to inspection under Sect. 91 comprises also the use of calcium sulphate to maintain interior cellulation as referred to above. This subjectmatter does not appear in the Specification as accepted.
