Patent GB-2475342-A (GB)
Title: Emulsion ink
Inventor: HAMILTON JOHN CHRISTOPHER
IPC: C09D11/02
Filed: 2009-11-17
Abstract: A water-in-oil (w/o) emulsion ink comprises an oil phase and an aqueous phase. The oil phase comprises a liquid resin (e.g. an alkyd resin) having a viscosity of 1000-10000 cP in an amount of 0.1-10 wt.% based on the total weight of the ink. The aqueous phase comprises pigment and when the pigment comprises carbon black, all of the carbon black in the ink has a pH of at least 5. The oil phase may further comprise an esterified vegetable oil. A process for preparing a w/o emulsion ink is also disclosed, which comprises adding an aqueous phase containing a pigment to an oil phase comprising a liquid resin having a viscosity of 1000-10000 cP. When the pigment comprises carbon black, all of the carbon black has a pH of at least 5. The emulsion ink is particularly useful in stencil printing, especially digital duplication.

Patent GB-331817-A (GB)
Title: Improvements in or relating to the destructive hydrogenation of coal, oils and the like
IPC: C10G1/00
Filed: 1929-04-02
Abstract: 331,817. Harrison, C. F. R., and Imperial Chemical Industries, Ltd. April 2, 1929. Hydrogenation, destructive.-Vapours resulting from the destructive hydrogenation of carbonaceous materials, such as coal and oils, in the liquid phase are superheated in the absence of hydrogenating catalysts and passed, together with hydrogen, over a hydrogenating catalyst at a temperature lower than that of the superheating stage. Superheating may be effected by passing the vapours, consisting of middle oils, petrol and hydrogen, over heated contact masses of a non- hydrogenating character, or the vapours may be cooled to condense the petrol and middle oils separately or together. The condensates are then vaporized, with or without hydrogen, superheated and the superheated vapours passed with hydrogen over hydrogenating catalysts. The superheating contact masses may consist of metals of the first three groups of the periodic system, e.g. aluminium or zinc or their compounds, with iron or chromium or their compounds. The catalysts in the final stage may be those known for this purpose, e.g. iron, nickel, cobalt, molybdenum, chromium or tin or their compounds. In superheating the vapours, the operations of heating and cooling are effected as rapidly as possible, e.g. the time of contact of the gases with the catalyst should not exceed ten seconds. A suspension of 1 part of bituminous coal in 2 parts of a heavy oil, resulting from a previous destructive hydrogenation, is hydrogenated at 200 atmospheres and at 420‹ to 440‹ C., the reaction products being passed over an electric heater into a reaction vessel at 500‹ to 600‹ C. containing iron coated with zinc. Hence the vapours pass into a vessel containing ferric oxide mixed with 10 per cent of molybdic acid at 420‹ to 450‹ C., this temperature being realised by mixing cold hydrogenating gas with the incoming vapours; alternatively the vessel might be utilized as a preheater.

Abstract: 419,814. Revolving-cylinder pumps. JOHNSON, G. W., 47, Lincoln's Inn Fields, London.-(American Engineering Co. ; Aramingo Avenue, Philadelphia, U.S.A.) April 8, 1933, No. 10559. [Class 102 (i).] In a revolving - cylinder pump, in which the cylinder body 33 rotates on a stationary valve 4 supported at both ends in the casing, a fluid distributer 15 is secured to one end of the valve, while the other end is supplied with lubricant by a pipe 93. The body 33 has radial bores with pistons 35 having pivoted slippers 37, which are held in engagement with the inner race of a roller bearing 39 by means of flanged rings 41. The outer race of the bearing 39 is mounted in a rectangular box 49, which is adjustable transversely for varying the stroke and for reversing the direction of pumping. The cylinder body carries a gear-wheel 61, which meshes with a pinion 63 on a driving shaft 64 mounted in bearings 65. The latter may be carried in a cover plate which can be bolted in various positions in order to vary the position of the driving shaft. The ports 8, 9 in the valve communicate by axial passages with passages in the fitting 15, which is secured to the valve by a clamp 14 and a stud 23. The fitting 15 has suction and discharge branches 18, 19, each branch having an alternative connection 21, 22. A gear-wheel 73 on the cylinder body drives two gear-wheel pumps 71, 72. The pump 71 circulates lubricant from a reservoir to an elevated tank, while the pump 72 draws lubricant from the elevated tank and discharges it by a pipe 79 to a passage 81 in the pump casing. The lubricant passes by bores 84 to a tray 85 in the box 49 and by further bores to the bearing 39. Lubricant also passes by a passage 88 to a chamber 89, from which it passes by a bore 91 to the gearing 61, and by the pipe 93 to an axial passage 25 in the valve. From the passage 25 the lubricant passes by passages 26 to recesses 27 in the valve surface.

Title: Improvements in system for compensation of electrical strain-gauge load cell non-linearity
IPC: G01G19/04
Filed: 1957-04-02
Abstract: 822,849. Weighing apparatus. REPUBLIC STEEL CORPORATION. April 2, 1957 [April 20, 1956], No. 10701/57. Class 40 (1). Weighing apparatus comprises transducers of the strain gauge type so arranged that when a load is applied, at least one transducer experiences a compressive force while at least one other experiences a tensile force. The apparatus is so arranged and the transducers are so matched that the non-linearities of the compressed members cancel out the non- linearities of the stretched members and the resultant output is uniform. Means are described whereby a platform carrying a railway track is supported by a plurality of such transducers where adjacent transducers are of the opposite type travelling both longitudinally along the track and laterally across the track. The simplest form of this latter case comprises four transducers disposed at the corners of a rectangle, the diagonally opposite transducers being of a similar type. Such an arrangement is described in detail in the Specification. The transducers may each comprise a bridge circuit separately excited as shown in Fig. 7. The outputs are added together by connecting these in series. The indicating system comprises a pointer 62 coupled to the pointer 60 of a potentiometer in a bridge circuit 51. The position of the indicator is controlled by a reversible motor 65. This motor is excited by the output of an amplifier 50 whose input is the difference between the output of bridge 51 and the sum of the outputs of the transducers.

In a double-beam betatron the energy of both beams can be adjusted separately in a circuit for the expansion or contraction winding W, Fig. 1, including a condenser C and two inverse parallel connected thyratrons V<SP>1</SP>, V2, by firing each thyratron after the expansion process associated with it, but before the next expansion process once again. In Fig. 3 where Ui is the voltage induced in the expansion winding by the accelerating flux and Uc is the condenser voltage, the current impulses I, II through the expansion winding at phases α1, α2 end the accelerating processes started at phases α = O, α = 180. The additional firings are at phases α3, α4 to change the condenser voltage to the values required for the expansion processes. The current impulses III, IV occur after the expansion processes are completed. Further firings of the other thyratron may be made at phases between phases α1, α2 and the additional firings at phases α3, α4 in order to produce an expansion impulse of any amplitude for any expansion phase. The firing impulses for the thyratrons are produced by adjustable phase shifters, in a circuit described in detail.
