Title: Electromagnetic apparatus  for measuring the flow velocity  of an electrically conductive fluid and a method of calibration  thereof
IPC: G01P5/08
Filed: 1973-10-03
Abstract: 1426253 Electromagnetic flowmeters  DONETSKY NAUCHNO-ISSLEDOVATELSKY UGOLNY INSTITUT and TALLINSKY ZAVOD IZMERITELNYKH PRIBOROV 3 Oct 1973 46130/73 Heading G1N An induction flowmeter for insertion in a pipeline carrying a conductive fluid is adapted to be easily calibrated and to have its operation checked. In the arrangement of Fig. 1 the flowmeter comprises two coaxially arranged pipes 1, 2 of electrically insulating or non-magnetic material provided with two groups of electrodes 4, 5. A magnetic field producing coil 3 is arranged in the space between the pipes to produce a magnetic field at right angles to the flow of fluid being measured in a pipe-line in which the meter is suspended by a pair of struts, Fig. 2 (not shown) and the electrodes 4, 5. Calibration. The meter is removed from the pipe-line, cowls 6 covering the ends of the duct formed by pipe 2 removed and the duct connected to a calibration source of fluid, and electrodes 5 connected via leads 15 to indicator 17 via amplifier 16. The fluid is then passed through pipe 2 at various known speeds and the respective readings on indicator 17 compared with the known velocity to provide line calibration. In addition a coefficient is introduced to account for the inequality of the p.d's sensed by electrodes 4, 5 when fluid at the same velocity flows through the duct of pipe 2 and through the area outside of pipe 1 and the pipeline, which coefficient depends on the dimensions of the apparatus.  Measurement.  After calibration the meter is inserted through a hole in the pipe-line, cowls 6 are replaced and electrodes 4 connected to the leads 15 instead of electrodes 5 so that indicator 17 gives the rate of fluid-flow. If the cowls are removed and electrodes 4 connected in pairs with electrodes 5, Fig. 4 (not shown) it is possible to measure the velocity difference of two flows passing simultaneously through pipe 2 and outside the meter. Checking. (Fig. 5) If it is desired to check the operation of the flowmeter in situ the arrangement of Fig. 5 is used wherein pipe 2 is provided with tubes 11 which extend outside the pipe line. Electrodes 4 are disconnected from the indicator 17 and electrodes 5 connected. End caps 12 are removed and a fluid similar to that flowing through the pipe-line is passed through pipe 2 at a known velocity. Increase of sensitivity. Figs. 6, 7 (not shown). A magnetic core may be placed inside the pipe 2 to increase the magnetic flux. In order to calibrate the apparatus the core is replaced by a circular magnetic core, for the period of calibration, mounted outside pipe 1. A formula is specified  for the dimensions of such a core.

Filed: 1971-10-14
Abstract: 1361868 Packaging foodstuffs OSCAR MAYER & CO Inc 14 Oct 1971 47820/71 Heading B8C  A method of forming a package comprises locating an object to be packaged within a zone defined at least in part by a flexible film containing a plasticizer constituent which is capable of polymerization when subjected to radiation from a high-energy source whereby the film is rigidified and therafter subjecting the film to such radiation to polymerize the plasticizer and rigidify the film to a desired extent. In the arrangement shown, oxygen barrier polyvinylidene chloride films 34, 35 are extruded from die slots 30a, 32a and polyvinyl chloride films 36, 37 are extruded from die slots 31a, 31b, the films then being passed through a cooling bath 38 from which they emerge as film laminates 40, 41 and move together with a product 46 to be packaged to a package-forming unit 23 of a known form such as that described in U.S.A. Specifications 3,129,549 and 3,083,106. A chain of packages 47 emerging from the unit 23 is subjected to a heater 24 and subsequently to irradiation from a high energy source 25 to produce cross-linking of the polymerizable plasticizer in the polyvinyl chloride laminµ, therefore rigidifying the film laminations in the packages 47. The high energy source may be an electron accelerator, radio-active elements, X-ray devices, coronadischarge devices or ultra-violet emitters. The chain of packages 47 then moves through a separator 26 of known form, from which individual packages are discharged on to a conveyer 48, and waste film material is collected on a roll 49. In another arrangement, Fig. 2 (not shown), only one film (59) is extruded, the other film (62) containing a plasticizer, being drawn off a roll (63) and the packages formed, being irradiated by the source 25 after separation in the unit (55). The apparatus may be used to produce "bubblepack" type packages, Fig. 3 (not shown), or packages comprising a base-board and a laminated cover section (81), Fig. 6 (not -shown).
