Title: An Improved Controller and Switch for Electric Motors.
Inventor: BUSH JOHN
Filed: 1902-06-05
Granted: 1903-05-14
Abstract: 12,846. Bush, J., and Medway, M. T. June 5. Switches. - In a switch of the kind described in Specification No. 23,323, A.D. 1900, for controlling motors, the motor when starting causes a brush to move over contacts to cut out resistances. The motor starting-gear puts the motor and brush in gear, and operates quickbreak and reversing switches. The circuit of a solenoid A, Figs. 1 and 2, is made and broken at intervals, after the motor is started, by a contact on a revolving shaft driven by a crank-pin on the main shaft, and the lever B and shaft b are oscillated by the movement of the core a. The rack C is brought into engagement with the holding and driving pawls d<3> and c when the starting-lever L is moved, and the pawl c is then oscillated by means of a crank-pin b<2> on the shaft b. The contacts c<1> on the rack-piece are thus moved over the resistance contacts c<2>. When the rack is near the end of its travel, a projection c<3> upon it, assisted by a spring, moves a switch arm F quickly to break the solenoid circuit. The movement of the lever L to stop the motor raises the rack from the pawls, and the spring c<4> then draws it to its original position, the switch F being also closed. In a modification, a pinion on the shaft b gears with the rack C, and the lever B is then arranged to drive the shaft b in one direction only through a ratchet-wheel and pawl.

Granted: 1903-08-20
Abstract: 22,078. Read Holliday & Sons, Turner, J., Dean, H., and Turner, J. Oct. 10. Dyes, artificial.-The sulphonic acids of the amines of the aromatic series, such as of aniline, toluidine, xylidene, and alpha- and #-naphthylamine, are caused to combine in aqueous solution with dinitrochlorbenzene 1 : 2 : 4 in presence of sodium acetate or a like body. The dinitro sulphonic acids of diphenylamine &c. obtained form dyes which give various shades of yellow and orange to animal fibres. These condensation products may be nitrated to give other colouring-matters, and by prolonged nitration at high temperature dyes which appear to have lost the sulpho group. For example, with nitric acid of 40‹ BÚ., and the temperature of the mixture at 70‹ C. a colouring- matter is obtained which will dye wool and silk fine greenish-yellow from an acid bath, or at 90‹ to 100‹ C., a colouring-matter dyeing wool a deep orange shade. By increasing the proportion of nitric acid, a dye-stuff of a still redder shade is obtained.

Abstract: 4556. Potter, F. D., and Jeffreys, R. D. Feb. 28, A.D. 1902, date applied for under Patents Act, A.D. 1901]. Superheaters, steam.-Several independent superheating-elements are separately connected to the boiler steam pipe 5 and the engine steam pipe 6 by pipes 7, 8, Figs. 2 and 6, each of which is fitted with a stop valve, so that any element can be isolated at will. The elements preferably consist each of a divided header 16, Fig. 5, and concentric tubes 12, 13, arranged as shown. Means for flooding the superheater automatically on the stoppage of the engine and draining it when the engine is started are also described. One form of such automatic apparatus is shown in Fig. 6. Water from the boiler is admitted to the superheater through the pipe 26 and the valve 28 ; it is discharged therefrom through the valve 29 and pipe 30. The valves 28, 29 are connected together so that one opens as the other shuts. The connecting-spindle passes through a cylinder 33 and carries a piston ; a spring constantly tends to open the flooding-valve and close the discharge valve. When the engine is started, steam is admitted to the cylinder 33 by a pipe connected to the engine stop valve, so as to close the flooding-valve and open the discharge valve. The engine cylinder is diagrammatically indicated at 36, and the stop valve at 39. Fig. 7 shows a modified arrangement in which the stop valve 39, when opened, closes an electric circuit by bringing together two spring arms 44. A solenoid 46 is thus energized to open a valve 43, which supplies fluid under pressure to the cylinder 33.

Granted: 1904-04-21
Abstract: 12,713. Lake, H. H., [Syndicat pour l'Exploitation des Inventions du Professeur Oettli]. June 5. White lead.-Consists in a process for the electrolytic manufacture of white lead. A one per cent. solution of common salt is distributed from a tank a by way of pipes c, c', to tanks b, of thoroughly-tarred wood, or, preferably, lined with lead, in which a series of pure lead plates l, preferably one centimetre thick and one square decimetre in area, is arranged to form the electrode. An electromotive force of five volts is required for each tank, and the current density should not exceed two ampÞres per square decimetre while the electrolyte is not allowed to rise above a temperature of 15‹ C. on account of the continuous circulation. The polarization of the electrodes owing to the deposition of lead hydrate is prevented by reversing the current at definite intervals. A stream of carbonic acid is passed to each tank, and the resulting white lead is drawn off by siphons b<1>, and the electrolyte is separated by a hydro-extractor e<1>, whence it is passed to a tank g and back to the circulating tank a. The hydrate may be drawn off, and the carbonation take place in a separate vessel, but the above method is preferred. The white lead may be dried slowly at a temperature not exceeding 50‹ C., or ground up with linseed oil into a paste ready for sale. A low-period alternating current may be employed, but this necessitates a much higher voltage. The tanks are preferably grouped in three series of ten, two series being worked while the third is idle. The following reactions are said to take place, viz. :-
