Title: Improvements in Instruments for Measuring Continuous Currents.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1897-10-05
Granted: 1898-08-06
Abstract: 22,851. Thompson, W. P., [Shallenberger, O. B.]. Oct. 5. Current meters.-A coil A, conveying current, is movable about a spindle J, on an iron ring Q, between which and a co-axial similar ring P a magnetic field is formed, the rings being fixed on blocks R, R<1> attached to the ends N, S of a permanent magnet or magnets. The coil A is balanced by another coil B, which may be a closed conducting-circuit to damp the movements of the spindle, or may also convey the current ; in the latter case both coils are wound on conducting- frames, to effect damping. Current is conveyed to the coil by two spiral phosphor-bronze springs C, D, carried by insulators on the spindle J, and connected to stationary arms E, F. The coil carries a pointer I, over a scale, not shown. The rings Q, P are made with gaps to permit the placing of the coils on them, the gaps being afterwards filled up with magnetic material, or each ring may consist of two semicircular pieces. The rings may be nearly surrounded by an iron ring M, secured adjustably between three screws ; this ring shields the magnetic field from outside influences, and also serves as a means for adjusting its uniformity, and the proportionality of the deflections, through a large angle.

Title: Improvements in the Manufacture of Carbons for Electrical Purposes.
Inventor: SAUNDERS CECIL LORD
Filed: 1898-02-08
Granted: 1899-01-21
Abstract: 3198. Saunders, C. L. Feb. 8. Carbon.-Relates to a process for preparing carbons for electric arc lights and for other electrical purposes. Consists essentially in effecting the necessary intimate and uniform mixture of the materials employed in a wet state, by the use of some of the ingredients in a liquid form. Any apparatus may be used. The crushed coke, lampblack, graphite, or other form of carbon is placed in a closed macerator having an agitator, such as A, and therein mixed with a suitable solvent for hydrocarbons, such as benzene, carbon bisulphide, eucalyptol, dead oil, &c., and with pitch, tar, or oils, and any other desired ingredient, such as sulphuric acid, phosphates, cyanides, wax, or salts of sodium, strontium, &c. The slimy mixture obtained passes gradually into a vapourtight wet-grinding machine, such as B, and from thence to a still C having agitator arms. The solvent driven off passes to a condenser D, thence to a separator G, for retaining water, and afterwards to a storage tank E, from which it is carried back to the macerator. The dry powder left in the still is transferred, while still hot, to the cylinder of a press, and forced into carbons of the required form. By adding the solvent only, the hydrocarbons present in coke may be dissolved out, the solvent recovered by ordinary distillation, and the heavy hydrocarbon obtained separately. The addition of pitch &c. is then made, and the process proceeds as above.

Title: Improvements in and connected with the Inking Apparatus for Printing Machines.
Inventor: NEWTON HENRY EDWARD
Filed: 1899-12-12
Granted: 1900-03-03
Abstract: 24,698. Newton, H. E., [Hoe, R.]. Dec. 12. Rotary machines; inking -apparatus.-Relates to the inking apparatus and to means for stopping the impression cylinder while the rest of the machine is run for working up the ink on the rollers. Fig. 1 shows a two - colour printing- machine having two forme cylinders 5 and an impression cylinder 8, the shafts 4,7 of which are mounted as shown in adjustable bearings 3, 6 in the frame 1. The cylinder 8 is driven by a spur-wheel 18 loose on its shaft 7, and driven by gearing 17, 15, 14 from the driving- shaft 12. The wheel 18 may be locked to the cylinder 8 by means of a locking-arm 21 on a shaft 20 journalled in the cylinder, the end of such arm 21 being adapted to engage a recess 22 in the wheel 18. On the opposite end of the shaft 20 is another locking-arm 23, which may be engaged with a notch in a block 24 fixed on the frame. When the locking-arm 23 is engaged with its notched block 24, the arm 21 is disengaged from the wheel 18, so that the cylinder 8 is locked and the wheel 18 is free to rotate. The wheel 18 drives the cylinders 5 by their gears 19. When the cylinder 8 is locked, its raised impression surface 32 is away from the cylinders 5, and the reduced part 33 of the cylinder is opposite the cylinders 5. The inking-apparatus I of each forme cylinder comprises the ink duct F, transfer roll 72, ink drum 73 on which run distributers 74, and transfer rolls 75, 76 which convey the ink to riders 77, 78 and forme-inking rollers 79. Other riders 80, 81, 82, 83 run on the forme-inking rollers 79. When working up the ink, the formeinking rollers 79 are prevented from coming into contact with the formes, but run on the distributing- surfaces 35 of the cylinders 5. At the ends of the formes on the cylinders 5 are radially-movable plates 37, which may be moved outwardly into position to lift the rollers 79 in their bearings away from the formes, by cams 45 on shafts 46. The shafts 46 on each cylinder are coupled so as to move together by arms 48 and a connecting-rod 47, either shaft having a square end for turning it by means of a key or other means. A reciprocating longitudinal motion is given to some of the riders 77 &c., such motion taking place when the forme-inking rollers 79 are not running on the formes. In the arrangement described, the rollers 77, 78, 81, and 83 are reciprocated by levers operated by grooved cams on the ends of the shafts 4 of the cylinders 5.

Patent GB-190018618-A (GB)
Title: Improvements in Electrical Indicating and Measuring Instruments.
Filed: 1900-10-18
Granted: 1901-10-18
Abstract: 18,618. British Thomson-Houston Co., [Robinson, L. T.]. Oct. 18. Current meters are provided with magnetic means for opposing the movements of pivoted coils from a zero position, constructed so that the relations of the controlling and deflecting forces are not affected by considerable variations in the strength of the stationary magnets which provide both forces. The magnets may be electrically excited. An astatic arrangement, suitable for use on a switchboard carrying large currents, is partly shown in Fig. 7. Two fixed two-pole magnets are magnetized to " saturation " by coils B, B<1>, and carry four pole-pieces N, S, which are externallycylindrical and have flat inner faces, with bevels f. A shaft M<1>, carried centrally between the polepieces by jewelled or other end bearings, is made in two parts insulated at the middle, where it' carries two metal discs R<1>, larger in diameter than the pole-pieces ; coils of the form shown in Fig. 8 are secured between the discs. The parts are made of substantial size, delicate construction being avoided. The discs and coils thus move in the short air-gaps and strong magnetic fields between the pole-pieces on the two magnets. The discs damp the movements of the parts. Current is supplied to the movable coils through the halves of the shaft, and two light flexible spiral conductors, which are arranged to control movement of the shaft as little as possible. The movement is controlled by two thin slips of magnetic material O, riveted in slots in the shaft, and situated in the longer air-gaps between the pole-pieces of each magnet. The slips are small and magnetically saturated, so that they change little with considerable variations in the strength of the magnets, and their changes in position produce no appreciable magnetic effects. They may be thin sheets of iron, or of copper electroplated with iron or nickel. The shaft also carries a counterbalanced pointer over a scale. The magnet and movable coils may be connected in parallel or series ; or the magnet coils may be supplied at roughly constant pressure, and the movable coil shunted by a resistance to carry the currents to be measured, or connected in series with resistances for measuring electric pressures. Otherwise permanent field magnets may be used. A single magnet may act on a long narrow coil Q, shown in cross-section in Fig. 6, enclosed in a metal tube R, which is supported between end bearings so as to turn on its longitudinal axis. The movement of the tube and coil is controlled by a thin magnetic slip 0 secured in the coil. The relative angular position of the coil and controlling- slip determines the sensitiveness at different parts of the scale. Two such tubes, coils, and slips may be joined in line by a short shaft, and situated in two fields produced between two opposed U-shaped magnets ; or the shaft may carry a tube and coil only in one field, and a controlling-slip in the other.
