Title: A process of obtaining ª‡-and ª‰-methylnaphthalene and fractions enriched in either of these compounds
IPC: C07C7/171
Filed: 1942-02-19
Abstract: 555,981. Alpha and beta methylnaphthalene. COULSON, E. A. Feb. 19, 1942, No. 2223. [Class 2 (iii)] Alpha-methylnaphthalene is separated from a mixture of α- and #-methyl naphthalene or a mixture containing the two isomers such as tar oil by a process which comprises sulphonating the mixture to produce the monosulphonic acids of oc- and #-methylnaphthalene and selectively hydrolysing the mixture to desulphonate the greater part of the α-isomer, which is finally recovered. The selective hydrolysis is preferably carried out by heat, and the product recovered by steam distillation. After the separation of the α-isomer, further hydrolysis results in the isolation of the #-isomer. This may be still further purified by sulphonation followed by fractional crystallization from dilute sulphuric .acid. The preferred temperature for the hydrolysis of the α-isomer is at or below 124‹C., and for the #-isomer from 124‹- 150‹C. In examples, (1) A neutral tar fraction boiling between 232‹-240‹C. is treated with 98 per cent. sulphuric acid in the presence of silver sulphate at a temperature below 30‹C. The reaction mixture is poured on crushed ice and the aqueous layer separated from the unsulphonated oil. The aqueous layer is heated to boiling and steam passed through. The α- methyl naphthalene is thus distilled off. The residue is heated to 145‹-150‹C. and again steam-distilled to give a product predominating in #-methyl naphthalene. (2) The fraction rich in #-methyl naphthalene obtained in example (1) is again sulphonated as in example (1) and the product fractionally crystallized and finally desulphonated to give pure #-methyl naphthalene.

Title: Improvements in or relating to electrical metering apparatus
IPC: G01R27/02
Filed: 1940-02-07
Abstract: 538,649. Telemetering. VUILLE, B. A., and WATFORD ELECTRIC & MANUFACTURING CO., Ltd. (Augier-Queyras.) Feb. 7, 1940, No. 2399. [Class 40 (i)] A self-balancing bridge controls the proportion of each of an indefinite number of successive time periods during which a meter shall be operated. In one arrangement, Fig. 1 (not shown), a first self-balancing bridge is controlled in accordance with the difference of temperature of the fluid in the flow and return pipes respectively of a boiler and controls one of the arms of a second self-balancing bridge the opposite arm of which varies with the rate of flow of the fluid. The balancing motor controls the point at which a constantly rotating snailshaped cam operates contacts over which alternating current is fed to a meter and thus the extent of operation of the meter in each rotation of the cam. In a modification, Fig. 2, a bridge set in accordance with the temperature difference referred to above controls the point at which a constantly driven pin 40 closes contacts 38. Contacts 42 operated at the same point in each rotation of the shaft carrying the pin 40 energize a relay 43 which locks up, deenergizes a brake magnet 45 and energizes a clutch magnet 50 to couple a water meter WM driven by the boiler fluid to the driving disc of an interrupter 52 which sends impulses to a meter 56. When the contact 38 is operated relay 43 is unlocked and the interrupter is stopped. The number of impulses delivered to the meter in a cycle thus depends on the rate of flow and the temperature difference of the incoming and outgoing fluid. A suitable clutch, in which however a pair of clutch magnets acts to couple the interrupter to the water meter when de-energized by means of a pair of pawls acting on a ratchet wheel, is illustrated in Figs. 3 and 4 (not shown). In a modification, Fig. 5 (not shown), such a clutch is used to give an intermittent drive to the final meter itself, the driving part of the clutch being coupled to the motor driving the pin 40. The meter registers degree-hours the bridge being controlled by the difference between a variable and a standard temperature. Specification 501,917, [Group XXXV], is referred to.
