Patent GB-189917118-A (GB)
Title: The Manufacture or Production of Chemical Compounds of the Aromatic Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1899-08-23
Granted: 1900-07-28
Abstract: 17,118. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Aug. 23. Medicinal preparations antiseptics. - (1) New aromatic compounds containing the group CH2X, in which X represents a halogen atom, are produced by acting upon aromatic oxycarboxylic acids, or aromatic oxyaldehydes with halogen methylic alcohols of the formula CH2Cl.OH, CH2Br.OH, and CH2I.OH in presence of suitable condensing-agents, such as strong mineral acids, zinc chloride, or phosphorus oxychloride or pentoxide. Salicylic acid, for example, yields a compound which probably has the formula C6H3(CH2Cl)(OH)COOH and is a remedy for skin disease. Such compounds are also prepared from chloromethylic alcohol and m- and p-oxybenzoic acid, #-oxynaphthoic acid, m- and p-cresotinic acid, anisic acid, the methyl and ethyl esters of some of these acids, salicylic aldehyde, and vanillin; and from bromomethylic and iodomethylic alcohol and salicylic acid and salicylic aldehyde. The process may be varied by acting upon a mixture of an aromatic oxycarboxylic acid or oxyaldehyde and formic aldehyde with concentrated haloid acids. (2) When the foregoing compounds are acted upon by hot water, the CH2X group is converted into the CH2OH group, and, when alcohols are used, the group CH2OR, in which R represents an alkyl, is produced. When the halogen compounds are acted upon by aromatic oxy compounds, hydrochloric acid is split off, and condensation products are formed. For example, such compounds are formed in presence of glacial acetic acid at 100‹-120‹ C. from the halogen methylic compounds and alpha- or #-naphthol, phenol, thymol, and isobutyl-o-cresol; and resorcin yields two condensation products. These compounds possess bactericidal properties, and are antiseptics suitable for internal and external use. Condensation products are also formed with elimination of hydrochloric acid, by the action of the halogen methylic compounds upon aromatic amines. For example, chloromethylic salicylic acid and phenetidine in ethereal solution yield a yellow compound which probably has the constitution C6H3(OH)(COOH). CH3NH3C6H4OC2H5.

Title: Improvements relating to Apparatus for Controlling Electric Motors.
Filed: 1902-06-21
Granted: 1903-01-08
Abstract: 14,138. Lake, H. H., [General Electric Co.]. June 21. Electric locomotives and motor vehicles.-Relates to apparatus whereby a number of electric motors, each taking current through a separate controller, can all be simultaneously and similarly controlled by one or more mastercontrollers. Each motor controller is provided with mechanism for moving it either backwards or forwards, and automatically stopping its movement after it has turned a predetermined number of steps. Such mechanism comprises a small electric motor F, a shaft D carrying a pair of longitudinally-sliding bevel-wheels E', E', and also a pinion C gearing with a toothed wheel B on the shaft of the controller, electromagnets H, H<1> for causing one or the other of the bevel-wheels to gear with a pinion F<1> on the motor shaft, a stepped spiral slot b in gear-wheels B, a rock arm S' hanging in said slot, a switch S<4> operated by the rocking of said arm and controlling the circuits of the electromagnets H, H<1>, a solenoid M for moving said arm radially of the gear-wheel, and a let-off or escapement P actuated by a magnet R and controlling the extent of the movement of the arm S'. When the circuit of one of the electromagnets H, H<1> is closed, one of the bevel-wheels is caused to gear with the motor pinion F<1>, which thereupon rotates the shaft D and turns the controller cylinder through a certain angular distance. Meanwhile, the movement of a switch lever U at the master-controller has energized the let-off magnet R a given number of times, thereby allowing the solenoid M to storeup energy in a spring, sufficient to move the rock arm S' radially a given distance as fast as it is permitted to do so by the slowly-turning spiral slot b. When the arm reaches its predetermined position, it catches on a shoulder b<2> in the said slot, and is then rocked until the switch arm S' is tilted far enough to open the circuit of the electromagnet and thus disconnect the bevel gear from the motor. The controller then remains at that point until similarly actuated again in either direction. The reversing-switch of each motor controller is operated by two solenoids Z, Z<1>, each in a separate circuit, and controlled by a doublepole single-throw switch X. Means may be provided for making and breaking the motor circuits as the bevel-wheels E<1>, E<2> are thrown into and out of gear.
