Title: Improvements in revolving-cylinder pumps
IPC: F04B1/107
Filed: 1933-04-10
Abstract: 419,815. Revolving - cylinder pumps. JOHNSON, G. W., 47, Lincoln's Inn Fields, London.-(American Engineering Co.; Aramingo Avenue, Philadelphia, U.S.A.) April 10, 1933, No. 10681. [Class 102 (i).] In a revolving-cylinder pump, in which two cylinder bodies 11, 12 revolve on a stationary valve 5 supported in bearings in the casing covers 2, 3 and in a central partition 4, one of the cylinder bodies is driven by a shaft 35 through gearing 36, 31, and the bodies are geared together by spindles 41 mounted in the partition 4 and carrying pinions 39, 43 which mesh with gear-wheels 38, 44 on the cylinder bodies. Each cylinder body has two or more sets of radial cylinder bores 13, 14, 15, 16 and the bores of the different sets are relatively staggered. The bores co-operate with ports 17, 18, 22-27 in the valve 5. The pistons 45, 46 of the bores 13, 14 carry pivoted slippers 51, which are retained by flanged rings 54 in engagement with the inner races of roller bearings 53. The latter are mounted in a guide box 57, which is adjustable by a rod 64 transversely to the valve for varying the stroke and for reversing the direction of pumping. The pistons of the cylinder block 12 engage similar bearings in a guide block 65 adjustable by a rod 66. The guide blocks are adjusted simultaneously in opposite directions by a rod 69, carrying a toothed segment 68 which engages a rack 67 on the rod 64. The rods 64, 66 are geared together by a spur wheel 72. The reactions of the discharge pressures of the two cylinder bodies are thus diametrically opposite. The ports 17, 22 communicate by axial passages 19 in the valve, an end fitting 74 and a pipe 76 with a pipe 81, and the ports 25, 27 also communicate with the pipe 81 by means of axial passages 29, an end fitting 75 and a pipe 78. The ports 18, 23, 24, 26 communicate in a similar manner with a pipe 82. A gear-wheel 87 on the cylinder body 11 drives two gear pumps, one of which raises oil from a reservoir to an elevated tank, while the other supplies oil from the tank to a pipe 91 and a passage 92 in the casing. The oil passes from the passage 92 by bores 93 to trays 95, 96 in the guide boxes 57, 65 and by a pipe 101 to the gearing 36, 31 and to a chamber 102. From the latter the oil passes by a pipe 103 to a central bore 104 in the valve 5 and by passages 106 to the surface of the valve. Specification 419,814 is referred to.

IPC: G11C13/06
Filed: 1959-03-26
Abstract: 901,921. Magnetic matrix stores. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 23, 1960 [March 26, 1959], No. 10692/59. Class 106 (1). [Also in Group XXXIX] Polarized light is used to read out a matrix store comprising storage elements of thin magnetic film. Printing techniques are used. A layer of zinc sulphide or of silicon monoxide may be deposited over the magnetic-film surfaces to amplify the rotation. Matrix store.-Thin magnetic film elements (1, 1) (1, 2), &c., Fig. 3, are arranged at the intersections of row conductors x1, x2, &c. and column conductors y1, y2, &c. The row and column conductors are parallel adjacent the elements. In Fig. 3, a row conductor x1 traverses adjacent elements (1, 1) and (1, 2) in opposite directions. In Fig. 5, the row conductors traverse all the elements in the same direction. The store is produced by printing techniques. The column conductors y1, y2, &c. are deposited on a glass substrate B, Fig. 4. An insulating layer N1 is deposited over the substrate B and the column conductors. Layer N1 is followed by the row conductors and a second insulating layer N2. Finally, ferromagnetic films SE of composition 83% Ni, 17% Fe and thickness less than 500 A are deposited over the cross-points of the row and column conductors. Reading.-Polarized light from a polarizer P, Fig. 2, is reflected by the magnetic film elements of the matrix M on to an analyser AN and a photomultiplier PC. On interrogation, any change on the magnetic state of a magnetic film element causes a change in the output of PC and in the voltage across resistor R. This voltage is amplified as shown. The magnetic film elements are interrogated one at a time. The light source L may be a cathode-ray tube, the cathode-ray beam of which is controlled so as to scan the magnetic elements in turn with a light beam.

Abstract: 981,218. Induction furnaces. AJAX MAGNETHERMIC CORPORATION. March 24, 1961 [March 24, 1960], No. 10926/61. Heading H5H. The magnetic fields and shaping of the channels of a twin coil submerged resistor induction furnace are such that the molten metal moves from the hearth 2 at a low temperature through the central channel 5 and then back to the hearth at a relatively higher temperature through the lateral channels 4 and 6, which is the opposite direction to the normal circulation in such furnaces. The transformer system, comprising a core 10 with two primary coils 8, produces a concentric field in the central channel 5 and eccentric fields in the lateral channels 4 and 6 in each of which the centre of the field lies to the side of the centre of the channel crosssection away from the adjacent primary coil 8. In the form shown the lateral channels 4 and 6 are longer than the central channel 5 which opens into the hearth 2 through a wide funnel. In an alternative form (Fig. 1, not shown), the channels 4, 5 and 6 are of equal length. The lower ends of the channels 4, 5 and 6 are curved as shown where they enter the connecting channel 7 which should be at least of equal or larger cross-section than the other channels. Temperature and flow patterns are given (Figs. 6-9, not shown) illustrating the difference between the furnace and that described in Specification 642,199.

Filed: 1943-07-07
Abstract: 576,501. Metal sulphates; sulphuric acid. HODGE, W. W. July 7, 1943, No. 11032. Drawings to Specification. [Classes 1 (ii) and 1 (iii)] Spent pickling solutions and sulphates are reclaimed by precipitating the sulphates contained in the solution with an organic compound of the group comprising ketones, eldehydes, esters and acids containing the carboxyl radical which are either water soluble or may be so rendered by the addition of a blending solvent (e.g., acetone or alcohol). The unreacted acid in the pickling solution is thereby rendered effective for further pickling operations if desired after removal of the organic compound by distillation and replacement with further sulphuric acid. The process may be applied to spent acid liquors containing copper, nickel, zinc and aluminium sulphate, but is particularly applicable to waste acid liquors containing ferrous sulphate with acetone as the preferred precipitant. The precipitation may be effected at room temperature, or alternatively at lower temperature (1-2‹C.) with a reduction of the amount of organic solvent required. The precipitated ferrous sulphate may be separated by centrifuge or filter, and dried to whichever hydrate of the salt is required.
