Patent GB-190115929-A (GB)
Title: Method for Providing Marble and other Stones or Cement with Deeply Penetrating Designs in Colour.
Inventor: HIPPE ERNST EBERHARD
Filed: 1901-08-07
Granted: 1902-07-17
Abstract: 15,929. Hippe, E. E., and Holm, T. Aug. 7. Painting and varnishing.-Relates to the production of coloured designs on marble, stone, cement, &c. by a process which enables sharp contour lines to be preserved while admitting of a deep penetration of the colour into the marble &c., so that the surface can be ground and polished, The contour lines are drawn on the surface with a pen or a fine brush moistened with a water-glass solution or a similar fluid capable of closing the pores. This solution is coloured black for the sake of distinctness. The line is painted several times over so as to penetrate deeply into the stone, which may be heated to facilitate the penetration. Coloured fluids which wi!! not mix, such as water, ammonia-water, glycerine, or spirits of wine on the one hand, and oil, turpentine, petroleum, ether, wax, resin, sulphur, &c. on the other are applied simultaneously on the two sides of the contour line. The fluids limit each other's expansion below the line, which thus retains its sharpness within the body of the marble. If the pattern is applied on both sides of a thin slab, it will extend right through it. One of the fluids may contain colouring material, and the other be uncoloured. If the latter is petroleum, benzine, ether, &c., it can be eliminated by heating the marble, or by means of suitable solvent, and the uncoloured part may then be coloured separately. When the colour is dissolved in wax, and applied to hot marble, the penetration can be increased by the use of a hot stamp or templet. The marble may be coloured throughout, portions being then protected by wax, petroleum, or an alcoholic solution of resin while a further colour is applied. One colour may be sub-coloured with another forced into the marble from the sides &c. Suction may be applied to the opposite side of a slab to increase penetration. A framework of metal strips curved to correspond with the contour lines on the marble can be used to facilitate the application of the colours, which are applied in the spaces enclosed by the strips.

Patent GB-190124816-A (GB)
Title: Improvements in Electric Railways.
Inventor: KINTNER CHARLES JACOB
Filed: 1901-12-05
Granted: 1902-06-05
Abstract: 24,816. Kintner, C. J. May 6, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Electric railways and tramways, signalling on.- In a sectional conductor block system with electromagnetic switches and with signalling arrangements for the blocks, passing places, bridges, crossings, &c., the sectional conductors r are connected to the main c on the passage of the vehicle by the switch arms s which are held by catches 17 in the closed position. The switches s are thrown by the electromagnets f which are excited by a shunt current flowing from the collector through the additional contacts 5 at the ends of the sections r through their coils to the rails or return t. The collector-wheel has a flange on one side to make contact with these pieces 5 on one side only so as to excite the forward section. The sect ons in the rear and in front of the occupied section are rendered dead and prevented from being excited by current from the excited section flowing through the magnet coils 15 in front and rear to the return and thereby causing the withdrawal of the catches 17 so that the switches s are opened and cannot be held closed. In parallel with these catches are lamps or signals 18 which are simultaneously excited to indicate the condition. Fig. 2 also shows the arrangement at a passing place e and a draw or swing bridge b. When the bridge is opened, it throws a switch k to connect the additional lamp signals 19 and the coils of the catch releasing magnets at the adjacent switches between the main and return. The same effect is produced, but only momentarily, when a vehicle runs on to the siding e where the additional contacts 5 are placed. The supply section is thus rendered dead and a vehicle can proceed in the ordinary manner on the main line. When the bridge b is closed and the section on it is excited by the approach of a vehicle, the magnet coil g, which operates a lock i for the bridge, and the signal bell &c. j receive current from the section. At rail crossings, the sectional conductors of the two lines are electrically connected so that, when either is excited by the approach of a vehicle, boch the adjacent sections on each line are cut out by their releasing-magnets, and the corresponding signals are given.

Granted: 1903-04-23
Abstract: 9803. Wildermann, M. April 28. Chlorine hydrogen.-An electrolytic cell for the decomposition of alkaline salts is divided into an electrolytic compartment and an alkali compartment by a partition of superimposed troughs 11, containing mercury with free surfaces exposed in both compartments, as described in Specifications No. 18,958, A.D. 1898, and No. 22,902, A.D. 1900, and is now provided with means for stirring the amalgam produced in the electrolytic compartment. In the form shown in Fig. 4, the cell is circular in plan, and the mercury troughs 11 are annular, each trough having a rib dipping in the next below to form the partition. The troughs are of iron nearly covered with ebonite or other insulating-material, and are carried by screws on iron uprights 13, which carry the negative terminal. The uprights 13 are connected together by a slotted iron cylinder 14, which may serve as an auxiliary electrode to promote solution of the alkali metal. Preferably this action is effected by placing in the mercury small pieces of carbon mixed with metal filings, or of carbon coated with metal, or wound with fine wire. Stirring-blades t are carried by a frame 27, supported by rollers on a rail 34, and attached to a central shaft 32, by which the stirrers are slowly revolved or circularly reciprocated. The cell is closed by three covers 18, 22, 21, and annular water seals ; the intermediate cover 22 is carried by the revolving frame 27. The outer cover 21 carries an insulated.metal ring supporting carbon anodes g ; the current density on these is kept small, to reduce disintegration. In a modified form, a revolving frame carries alternate mercury troughs, the intervening troughs being stationary, and each trough carries blades to stir the mercury in the next lower. In another modification, the cell is rectangular, and stirrers, such as those shown in Fig. 4, are carried by straight reciprocating frames. In either arrangement, the stirring may be done only at intervals, if desired.
