Title: Improvements in Electric Arc Lamps.
Inventor: ARTER ARTHUR MARSHALL
Filed: 1898-06-14
Granted: 1899-06-02
Abstract: 13,304. Arter, A. M. June 14. Arc lamps.-Solenoid regulating - mechanism is arranged as shown. The carbon-holders are connected by rods, 'a chain 21, and cords 5, 6 to opposite sides of a pulley P, which may have two grooves of different sizes to allow unequal movements of the carbons. The cord 5 from the heavier upper holder 1 passes over a stationary guide - wheel 7. The pulley P is supported by a frame 19, pivoted at 17, and a spring 20. The pivot 17 may be below the pulley 7, as shown, or may be coaxial with the pulley. A cord 13 is attached to and wound on a part 12 of the pulley, of small diameter, and carries a lever 16, on which is the core 14 of a series or differentially-wound solenoid 15. Or the cord 13 may itself carry the core. A dash-pot controls the movements of the core or frame 19. In operation, the pull of the heavier upper holder on one side of the pulley is balanced by the pull of the cord 13 due to the solenoid on the other. The chain 21 prevents the cord 6 being lifted from the pulley if the lower holder is lifted. In a modification, the lamp is inverted, the regulating-mechanism being connected by cords with rods which extend upwards and carry the carbon-holders. In another modification, descrihed also in Specification No. 27.636, A.D. 1898, the pulley is of larger size and slotted to pass the pivot 17. both cords depending directly from it ; it is weighted to compensate for the varying difference in weight of the carbons, when continuous current is used. A toothed wheel and racks may be used instead of the pulley and cords. For alternating current, the solenoid core consists of a series of flat discs.

Title: Improvements in and connected with the Manufacture of Artificial Camphor from Hydrocarbon Oils of the Terpene Series.
Inventor: WOODS JOHN EDWARD TENISON
Filed: 1898-06-20
Granted: 1899-09-20
Abstract: 13,688. Woods, J. E. T. June 20. Camphors; camphoric acid; camphenes.-Relates to the manufacture of camphor artificially from hydrocarbon oils of the terpene series. (1) Monohydrochloride of terebene, which is produced by the action of hydrochloric-acid gas upon American turpentine, or the like, and is purified by sublimation in a current of steam, is converted into solid camphene by boiling it with acetate of soda and a caustic alkali or alkaline carbonate. The camphene is then oxidized to camphor by heating it with an alkaline permanganate, chromate, bichromate, ferrate, or chlorate, and very dilute sulphuric acid. The camphene may also be produced by agitating turpentine with very strong sulphuric acid. (2) Camphoric acid (C10H16O4) is produced by subjecting American turpentine, or other terpene oils, to the prolonged action of hot air and steam, hydrogen peroxide being also formed in the reaction. The aqueous solution of this camphoric acid is then reduced to camphor by means of nascent hydrogen, which is produced either by electrolysing the solution, or by adding to it zinc or iron and dilute sulphuric acid. Alternatively, the camphoric acid is boiled with three equivalents of camphene in the presence of acetate or formate of soda, whereby both the camphoric acid and the camphene are converted into camphor.
