Title: A method of determining the particle size distribution of a dust and a device for carrying out the method
IPC: G01N15/02
Filed: 1966-12-23
Abstract: 1,118,047. Centrifugal separators, gas filter for particle analysis. SVENSKA FLAKTFABRIKEN, A.B. 23 Dec., 1966 [30 Dec., 1965], No. 57793/66. Headings BIT and B2P. The particle size distribution of a dust, produced in an industrial process and dispersed in a gas stream discharged from the process, is determined by withdrawing from the gas stream a partial representative stream and immediately passing it in series through two portable analytical cyclones with known efficiency curves and a filter element of known weight, after which the amounts of dust collected in the cyclones and on the filter element are weighed and the numerical values obtained are analyzed in known manner. As shown in Fig. 1, the gas sample is withdrawn from the main stream in a flue 1 by means of a probe 3 and passed via a cooling pipe 4 into cyclones 5, 7 contained in a heatinsulated casing 14, Fig. 2, within which an electric heater 18 is provided in order to maintain the gas temperature above the dew point temperature to prevent condensation in the cyclones. The latter have removable covers 16, 17 and have dust containers 6, 8 detachably secured at their lower ends. A filter is connected to the cyclone 7 and comprises a housing 9, Fig. 3, containing a filter element in the form of a sheet 31 of glass fibre supported by a net 32 and clamped between upper and lower portions 22, 26 of the housing. The upper portion is provided with a gas inlet 23, heat insulation 24 and an electric heater 25. The lower portion is provided with an orifice plate 27, a clean gas outlet 30, a thermometer 37 and pressure tappings 28, 29 connected by hoses 39, 35, Fig. 1, to a micromanometer 36. The gas outlet 30 is connected by a hose 10 to a fan 11 driven by an electric motor 12 fed through an adjustable transformer 13. At the start of a sampling operation, the gas velocity in the flue 1 is measured by a Pitot tube connected to the micromanometer 36. This determines the size of probe to be selected. The gas temperature and the dew point are measured by thermometer to decide whether use is to be made of the cooling pipe 4 or of the heaters 18 and 25. The fan 11 is then started and its speed adjusted by the transformer 13 to ensure normal gas flow through the cyclones, the flow being determined by means of the orifice plate 27 in conjunction with the micromanometer 36 and the thermometer 37. When sufficient dust has accumulated in the containers 6, 8 and on the filter element 31, sampling is discontinued and the amounts of dust collected determined and analyzed.

Filed: 1970-12-09
Abstract: 1317629 Wells &c SCHLUMBERGER TECHNOLOGY CORP 9 Dec 1970 [15 Dec 1969] 58405/70 Heading E1F In a well tool comprising a mandrel or body 11, slips 43 for anchoring the tool in a well, an expander 39 movable downwardly to set the slips, means are provided for translating upward force on the mandrel to downward force on the expander to retain the slips in set condition. The tool (a packer) is lowered to the setting position in the well and the mandrel is rotated to the right to free threads 64 on a segmented clutch nut 59 from threads 65 on the mandrel. The clutch nut is carried by the lower housing part 50 of a cage 48 having an upper housing part 49 which carries drag blocks 55 and which is linked to the slips. The mandrel is lowered relative to the cage to cause a sleeve 17 carrying packing 19 to press downwardly on the expander to set the slips. The packing is then set and a part 34 on the mandrel blocks a bypass passage 18 within the packing. As the mandrel moves downwardly its teeth 66 ratchet within the clutch nut and finally lock the packer in its set condition. Upward force on the mandrel resultant upon a pull on the packer support pipe, or on well pressure below the packer, causes the housing part 50 to move upwardly relative to the part 49 to force the segments of a cam ring 78 radially inwardly to cause a segmented clutch ring 85 to grip a sleeve 47 depending from the expander so that further upward force on the mandrel is translated to a downward force on the expander. The packer is released by rotating and pulling upwardly on the mandrel, the threads 66 being left handed so that the rotation raises the mandrel relative to the cage.
