Title: An Automatic Charging Device for Electric Motor Carriages.
Inventor: MUEHLBERG ALBERT
Filed: 1899-10-27
Granted: 1900-06-30
Abstract: 21,470. M³hlberg, A. Oct. 27. Distributing. - Consists of automatic means for charging electric motor carriages at suitable stations without the necessity for switching resistances in and out by hand during the charging operation. To this end the carriages are furnished with trolleys or brushes which are adapted to make contact with conductors I, II, III at the charging-station, which conductors are in separate sections and are connected with the generators through different resistances. During charging, the carriage is caused to progress slowly under these conductors, with the result that the resistances are progressively reduced as the charging approaches completion.

Title: Improvements in, or connected with, the Manufacture and Production of Naphthalene Compounds and their Employment in Dyeing and Printing.
Inventor: JOHNSON JAMES YATE
Filed: 1900-12-31
Granted: 1901-12-14
Abstract: 23,887. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Dec. 31. Dyes, artificial. - Tetrahydroxynaphthalene, which dyes animal fibre directly and is capable of combining with metallic mordants, is produced and is separated from other polyhydroxynaphthalenes as follows : A naphthazarin solution is prepared by acting upon 1 : 5-dinitronaphthalene with fuming sulphuric acid and sulphur, and then finely-divided iron or zinc is added in small quantities at a time during half an hour whilst boiling the mixture. By this process the naphthazarin is reduced to tetrahydroxynaphthalene, and the polyhydroxynaphthoquinones which accompany the naphthazarin are reduced to polyhydroxynaphthalenes. Upon filtering the mixture, the polyhydroxynaphthalenes are left on the filter, and on cooling the filtrate the tetrahydroxynaphthalene separates in small brown needles. The naphthazarin may be isolated before reduction, or in place of it bodies such as those described in Specifications No. 3828, A.D. 1894, and No. 890, A.D. 1900, may be employed. TetTahvdroxynaphthalene dyes unmordanted wool brown, and cotton mordanted with alumina a yellowish shade which becomes darker on exposure to air. The dyeings on unmordanted material are darkened by oxidizing, and chromates yield fast black lakes. The dyeings on unmordanted material yield black metallic lakes with chromates or other oxidizing- agents such as air. These metallic lakes differ in shade from the corresponding naphthazarin lakes.

Title: Improvements in the Construction of Letter Boxes and such like, and Means for Securing the Contents therein.
Inventor: ADAIR JOHN
Filed: 1901-06-25
Granted: 1902-06-25
Abstract: 12,890. Adair, J. June 25. Letter-boxes.-To prevent the pilfering of the contents, the letters are inserted through an aperture, normally closed by a door y, Fig. 1, into a compartment E which extends diametrically through a revolving drum D, having a series of recesses M around the circumference to give a hold for rotation by the hand. The drum being rotated in the direction of the arrow 1, the letters fall into a receiver underneath. Balls C resting on the drum and moving in suitably-shaped ears N, prevent the drum from rotating in the reverse direction. Toothed plates R', R<2> are intended to prevent the pilfering of letters by means of a string &c. In a modification, Fig. 3, a tray T mounted at one end on a weighted disc D, and at the other end on a support, the disc and the support being carried on a shaft B, serves to receive the letters. The disc is rotated by means of a handle S, working in a slot to bring the tray into the topmost position, as shown in dotted lines, to receive the letters. When the disc is released, it is rotated by the weight W, which brings the tray into the position shown in full lines, to deposit the letters in a receiver underneath. A pin moving in a slot S<1>, S<2> in the disc may serve as a stop. Toothed plates, shaped as at P<1> or P<2>, may be used to prevent the fraudulent withdrawal of the letters, and the sides 5, 6 of the tray are also serrated for a like purpose. The disc may be also adapted to move in one direction only, in which case an additional toothed plate P<3> is used. Or the sides of the tray may be fixed, the bottom of the tray, on which the letters are dropped, being circular and attached to the rotating disc, so that, when the disc is rotated, the suitably-shaped side of the tray will arrest the letters, which fall into a receiver when the bottom ceases to support them. In another modification, Fig. 7, a receiver R mounted on a weighted swinging plate D<1>, actuated by a handle S, encloses the letters on insertion, and, by swinging the plate D' in the direction of the arrow, the receiver, which is open at the bottom, moves the letters along a bottom plate P<4> until they fall into a receptacle underneath in the direction indicated by the arrow 2. A toothed plate T', and serrations on the lower edges of the receiver R, serve to prevent the letters from being tampered with. The plate P<4> may be corrugated to drain off water and to facilitate the removal of the letters from it, the receiver being also shaped to remove the letters from the plate or the receiver may be fixed, and the plate P<4> movable. The box may have separate entrances for small and large letters &c. Instead of toothed plates, hinged spikes may be used.

Granted: 1902-08-14
Abstract: 11,990. Boult, A. J., [Kennicott, C. L.]. May 26. Feedwater, purifying. - Relates to apparatus for producing soft water in generating steam for rail- road and other purposes. The settling tank A is sur- rounded by an annular tank B for the purified water, and centrally within it is the downtake A' containing the lime-water chamber C. A pipe C' delivering at the lower end of the chamber C is supplied with soft water from the tank G, and with milk of lime, at intervals, from the tank F. The part of the chamber C above the gauze C<7> forms a mixing- chamber for the lime water rising through the gauze, the soda or other reagent from the pipe M, and the hard water from the pipe L. A stirrer C<6> and a similar one at the bottom of the tank are provided. The mixture flows over the edge of the chamber C into the downtake A' and thence up through the settling chamber A and filter S<2>. From the top of the chamber A the soft water is conveyed to the tank B by a pipe deliver- ing just over the outlet valve at the bottom of the tank, freezing of the valve being thus prevented. Danger of freezing in other parts of the apparatus is minimized by leading the supply pipe J up through the downtake A<1>, and by the central posi- tion of the lime-water tank. The tanks A, C have independent discharge outlets for mud &c., that of the tank C extending downwards through the bottom of the tank A. The tank G is supplied with soft water by the revolving dipper H. The hard water is received in a tank E, from which it is discharged into a water wheel D. A float K in the tank E is connected by cords with the pivoted pipes K<3>, K<4> in the soft-water tank G and soda tank I, so that the discharge from these tanks depends on the head in the tank E. The barrels &c. containing the lime or other reagent required are hoisted to the top of the apparatus by a drum which is loose on the water-wheel shaft and is thrown into operation by a friction clutch, but is normally in contact with a fixed friction disc. At the top of the apparatus is a hinged curved bracket, Fig. 4, which turns up to allow the barrel to pass and then drops back under the barrel.
