Title: Polymerization modifiers and method of polymerizing monovinyl aromatic compounds
Inventor: WEHR HENRY WILLIAM
IPC: C08F2/36
Filed: 1953-05-04
Abstract: A monoethylenically unsaturated organic composition comprising at least 85 per cent of a monovinyl aromatic compound is polymerized in the presence of 0.001 to 5 per cent of an unsaturated dimer of an a -methyl styrene.  Monovinyl compounds specified are styrene; ar-chloro-, p-chloro-, ar-dichloro-, m-ethyl-, p-isopropyl- and ar-dimethyl-styrenes; o, m-, p- and ar-ethyl-vinyltoluenes, vinyl naphthalene and mixtures.  They may be copolymerized with vinyl and vinylidene chlorides, ethyl acrylate, methyl methacrylate, acrylonitrile, vinyl acetate, methylisopropenyl ketone and a -methyl and p-methyl-a -methyl styrenes.  The dimers, which act as modifying agents and may be added prior to or during the polymerization, may be derived from a -methyl styrene and its p-methyl-, p-ethyl-, p-isopropyl-, m-ethyl-, m-methyl-, ar-dimethyl-, ar-chloro-, 3,4 - dichloro -, ar - chloro - ar - methyl -, ar - diethyl- and ar-methyl-ar-isopropyl-derivatives.  The dimers, which may be prepared as described in U.S.A. Specification 2,429,719, are mixed isomers of 1- and 2-pentenes and may contain minor amounts of a saturated dimer, e.g. an indan derivative.  The polymerization may be carried out in bulk, optionally with catalysts such as benzoyl, acetylbenzoyl and di-t.-butyl peroxides, t.-butyl hydroperoxide and t.-butyl perbenzoate, or in aqueous emulsion, optionally using hydrogen peroxide or ammonium or potassium persulphate and coagulating the product with sodium chloride, hydrochloric acid or aluminium sulphate.  Examples 1 to 4 describe the production of granules by crushing bulk polymerization products and example 5 describes an emulsion process using trisodium phosphate, the dihexyl ester of sodium sulphosuccinic acid and an alkali metal salt of rosin.ALSO:a -Methyl styrenes are dimerized, as described in U.S.A Specification 2,429,719, by heating at a temperature of from 70 DEG to 80 DEG  F. in admixture with an aqueous 60 per cent solution of sulphuric acid in amount corresponding to 4 parts by volume of monomer and for a period of 8 hours to obtain the dimer in substantially quantitative yield.

Patent GB-220066-A (GB)
Title: Method of, and means for operating automatically voltage regulators of current rectifiers
IPC: G05F1/147
Filed: 1923-05-09
Abstract: 220,066. Rogers, G., and Thurman, A. T. May 9, 1923. Regulation, automatic.-The voltage of a direct current supply 4, 5, 6 derived from mercury arc or other rectifiers fed by the secondary of alternating current transformers, is regulated by movement of contacts 10 over tappings from the primaries 11 of the transformers, the contacts being moved through distances equal to the spacing of the tappings by a motor 12 which is controlled by the voltage of the direct current mains 1, 2, 3. A voltage relay operated by solenoids 18, 19 connected across the supply 4, 6, comprises a spring-pressed switch 20 which is closed when the voltage falls below a predetermined range and a switch 21 which is closed when the voltage rises above the range. Upon closure of either of the switches 20, 21 current passes from the supply 5 through a resistance 37, and one of the switches to one of two solenoids 22, 23, and thence, through knockoff switches 40, which are operated by the moving contacts 10 at the ends of their travel, to either the supply 6 or 4. Time-lags may be associated with the solenoids 18, 19 or 22, 23. Energization of solenoid 22 operates a shaft 24 to close switches 26, 27 and to open a switch 25, completing, the motor circuit through switch 27 so that the motor rotates screwed shafts 16 upon which the moving contacts 10 are mounted, so as to move the latter to increase the voltage. Upon the voltage returning to its normal value, switch 20 is opened, but the solenoid 22 is not deenergized because the closure of the switch 26 completed a shunt circuit around switch 20 through a conductor 34, a rotary contact 31 carried by one of the shafts 16 and a contact 36. The motor continues to rotate until an insulating block 32 comes under the contact 36 and thereby interrupts the shunt circuit and de-energizes the solenoid 22. The pitch of the screwed shaft is such that one revolution thereof corresponds to a movement of contacts 10 from one tapping to another and the block 32 is positioned so as to interrupt the shunt circuit when the contact 10 is properly in engagement with one of the tappings. Closure of the switch 24, upon deenergization of the solenoid 22, short circuits the motor so as to stop it abruptly. Energization of the solenoid 23 operates the shaft 24 and the corresponding switches 28, 29, 30 to drive the motor in the ooposite direction. If the motor is under the control of the solenoid 22 due to previous operation of the switch 20 and the. other switch becomes closed, the solenoid 23 will not neutralize the action of the solenoid 23 because the former has a weaker action due to the interposition of the resistance 37 in its circuit. A similar action occurs upon the operation of the switch 20 while the motor is under the control of the solenoid 23. Upon failure of the rectifiers, switches 38, 39 are operated to interrupt the circuit through the resistance 37. The supply 4, 5, 6, is connected to the direct current mains 1, 2, 3 by a switch 7.
