Title: Improvements in or relating to counting and/or indicating and/or recording mechanismfor use with venturi flumes
IPC: G01F1/37
Filed: 1934-03-16
Abstract: 438,510. Electric signalling systems. KENT, Ltd., G., 199, High Holborn, London, GROUT, J. A. M., and LINFORD, A., Biscot Road Works, Luton, Bedfordshire. March 16, 1934, No. 8380. [Class 40 (i)] In a system for measuring flow of fluid through Venturi flumes or over weirs, two electrical potentials corresponding to the head at one point in the flume, and the square root of the differential head between two points are produced, the two potentials being fed to a device which affords a response dependent on the product of the two values. As shown in the Figure, floats 3 and 4 drive the two sides of a differential gear 7 in accordance with the heads, called hereafter H2 and H1 at the two points 1 and 2. The driven side of the gear moves in accordance with the differential head (H1-H2) and drives the cam 8 to move arm 11 over resistance 12. The cam is cut so that the voltgae in the circuit 29, 30 is proportional to #H1-H2. The side of the differential 7 driven by float 3 drives cam 23 to move wiper 26 over resistance 27 and this cam 23 is cut so that the voltage in circuit 32, 33 is proportional to the head H2. Consequently the coil 34 rotates at a rate proportional to H2 #H1-H2 and this rotation is transmitted to the spindle 35 of the meter which gives an indication of the flow through the flume. The voltmeters 21 and 28 show the voltage in the lines 29, 30 and 32 33 respectively and these voltmeters can be calibrated to indicate #H1-H2 and H2 respectively if desired. Adjustable resistances 18, 18<1> enable line losses to be compensated and current-controlling devices 17, 17<1> (such as iron hydrogen lamps) serve to maintain a constant current in the system irrespective of fluctuations in the supply mains. Specification 328,659, [Class 69 (i)], is referred to.
Patent GB-269511-A (GB)
IPC: H01F1/24
Filed: 1927-03-23
Abstract: 269,511. Standard Telephones & Cables, Ltd., (Assignees of Andrews, J. TV., and Gillis, R.). April 17, 1926, [Convention date]. Transformers.-Magnet cores for transformers &c. are made of finely-divided particles of magnetic material and an insulator comprising a combination of an acid, an alkali, and a secondary insulator or vehicle for the acid and alkali. The magnetic material is preferably an alloy consisting of nickel and iron, the nickel being more than 25 per cent of the whole, for example 78¢ parts of nickel to 21¢ parts of iron. The particles should be of such a size that all pass through a 120-mesh screen. The particles are annealed at from 750‹ C. to 980‹ C., preferably about 925‹ C., in an enclosed container, the caked mass being then again reduced to a finely-divided form. The insulator consists of 5¢ parts of chromic acid, 5 parts of talc, and 4¢ parts of water glass dissolved in water. The alloy particles are added to the solution and the entire mass is boiled to dryness with constant stirring to prevent caking and ensure a thorough coating of the individual dust particles. The dried insulated dust particles are compressed into cores or rings under high pressure and annealed at about 500‹ C. The cores are then boiled in water to remove soluble substances and dried at 100‹ C. A number of rings are then stacked coaxially to form a core on which the coils are wound. In cases where mechanical strength is not essential, chromic acid alone may be used as the insulator. Molybdic, tungstic, antimonious, phosphoric, or other acids may be used instead of chromic acid, and water glass and talc may be replaced by other alkalies, such as sodium hydroxide or aluminate. For a secondary insulator zinc oxide, aluminium oxide, and barium oxide may be used instead of talc. In a modification the metallic particles are treated with a solution of an acid and an alkali, whereby they are given a primary insulating coating, after which they are dried and mixed with dry acid and a secondary insulator until they have received a second insulating coating. The insulator for the primary coating consists of a mixture of 1“ parts of dry silicic acid to 1 part of water glass dissolved in water. The alloy particles are added and the mixture boiled to dryness with constant stirring. The dry coated particles are then placed in a revolving drum and a mixture of 1 part of dry silicic acid and 1¢ parts of ferric oxide is added to give a secondary insulating coating. The coated dust particles are then annealed at 468‹ C., pressed to the required shape, and annealed at from 480‹ C. to 950‹ C. Antimonic, arsenious, arsenic, molybdic, tungstic, antimonious, phosphoric or other acids may replace the silicic acid, and the water glass and ferric oxide may be replaced by other alkalies such as sodium metasilicate or zincate, or by secondary insulators such as sta,nnic oxide, manganese dioxide, and cupric oxide.
