Patent GB-229564-A (GB)
IPC: H01H71/14
Filed: 1924-07-19
Abstract: 229,564. Paul, M. March 13, 1924. [Convention date]. Automatic circuit-breakers.-An element, Fig. 1, of some ferro-magnetic substance such as iron, nickel, or an alloy of 92 per cent nickel and 8 per cent copper, is inserted as at B, Fig. 2a, in the magnetic circuit of a permanent magnet A and its armature D, the element being insulated from the magnet by mica sheets C1, C2. The element is connected in the circuit to be protected and upon overload, the heat generated in the element lowers its magnetic permeability and reduces the force of attraction upon the armature which is forced upwards by a spring G causing the circuit to be broken at contacts E1, F1 and E2, F2. A rod J fixed to the armature serves as an indicator and also as a means for resetting the apparatus. Another element, Fig. 1, may be inserted in the armature if desired, and according to a further modification. two elements in series are inserted in the poles of the magnet A. Fig. 4<a> shows a modification which prevents closure of the circuit by hand if the overload persists. To close the circuit, a rod M connected to a conducting disc N is depressed. The disc N carries the armature D with it and closes the contacts E1, F1, E2, F2. The circuit however is not closed till the rod M is released amd the disc N is allowed to move upwards again to connect contacts Q1, Q2 which are in series with the other contacts.

A strand 12 is passed through steam chamber 14 or contacted with electrolytic size, containing ions of charge opposite to that of the particles, to moisten and partially charge the strand. The resulting strand, having separated filaments, is then passed through the fluidised bed 48 of impregnant particles, the particles being fluidised by gas blown upwards through porous plate 46. The plate, charged by an electrostatic generator 60, charges the particles and induces an opposite charge on the filaments as they contact the cross-members 22 of the grounded electrodes 20 and 30. Alternatively the nip rollers 16 or the bath 14 may be grounded. In a second arrangement the filaments may be charged by an electrostatic generator 70, when switch 78 is switched. The electrode 20 may pivot on the extended upper cross-member 22, the amount of pivot being adjusted by resilience of spring 26. The fluidised bed may also be vibrated by vibrator 56. The impregnated filaments are then dried. heated or cooled in chamber 80, bundled at 82, extruded at 83 and wound up at 84. The filaments may be e.g. glass fibre, mineral, B, C, Si or Sic. The impregnant may be e.g. polyethylene, polypropylene or PVC.

IPC: B01J23/89
Filed: 1960-05-20
Abstract: Impurities are removed from organic liquids by the use of a large surfaced carrier containing reduced copper.  Prior to use the carrier may be treated with hydrogen, carbon monoxide, oxygen or mixtures containing these.  The organic liquids may belong to widely different classes, the following individual examples being given; normal-heptane, iso-octane, cyclohexane, cyclohexene, methylcyclohexane, benzene, toluene, chlorbenzene, carbon tetrachloride, trichloroethylene, methanol, ethanol, diethyl ether, dibutyl ether, tetrahydrofuran, dioxane, and ethyl acetate. Substances which under normal conditions are not liquid may also be purified according to the process by liquefying them under pressure in the case of gases, by bringing them in the fused state at elevated temperature into contact with supported copper, or by treating suitable solutions of them, e.g. propylene, butane, butadiene-(1,3), naphthalene and durene.  Examples of impurities include oxygen, halogen, hydrogen peroxide, hydrogen sulphide, sulphur dioxide, hydrogen halides, carbon oxysulphide, iron pentacarbonyl, ammonia, acetylene, thiophene and amines.  Suitable carriers are magnesium silicate and the oxides, hydroxides, carbonates and silicates of iron, manganese, cobalt and/or nickel.  The addition of activators, such as compounds of the alkaline earths, zinc, cadmium, chromium, molybdenum, tungsten, vanadium, titanium, gold, and/or thorium, is recommended.  The ratio by weight of copper to the other compounds of the composition may lie between 1 : 20 and 20 : 1.  Specification 869,052 is referred to.

Abstract: 863,153. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 7, 1957 [June 11, 1956], No. 18143/57. Class 40 (1). [Also in Groups XIX and XXXIX] A magnetic switching matrix, Fig. 4, which is used to drive a matrix store is so operated as to avoid spurious outputs in the leads X individual to the cones 60. The cores are normally in a state of negative saturation (a, Fig. 5). A read pulse is transmitted over a lead X when a core is switched to a state of positive saturation (to c and then d), by a pulse on a selected set winding 62 and a pulse on all but the selected one of the bias windings 64. When the column including the selected bias winding is subsequently energized, the selected core returns to a state of negative saturation (b) and a write pulse is transmitted over X. All the bias windings of the matrix may first be energized, the windings of only the selected column being de-energized when the selected row is pulsed (see Fig. 6, B). Alternatively the non-selected column may be biased in two steps, tubes 38 being made conductive first and tube 38<SP>1</SP> being made conductive at the beginning of the set pulse (see Fig. 6, A). Only a small flux change (b to e) is involved in the second step.
