Title: Improvements in or relating to the decomposition of liquid hydrocarbons
IPC: C10G9/24
Filed: 1928-04-04
Abstract: 316,905. Bethenod, J. April 4, 1928. Oil gas.-Liquid hydrocarbons such as petroleum and coal tar oil are decomposed by electrical conductors of high melting point heated to a temperature above 800‹ C., means being provided for preventing deposition of carbon on the conductors and for circulating the hydrocarbon under treatment. Thus, a series of conductors carried on a revolving shaft may be immersed in the hydrocarbon, and each conductor may be kept clean by rubbing against a brush; the current may also be supplied through rubbing or wiping contacts. Alternatively, the conductors may be axially arranged in tubes through which the hydrocarbon is passed, the tubes being preferably of increasing cross-section to facilitate separation of the gases, or conductors so arranged in tubes may be immersed in a vat containing the hydrocarbon, the hydrocarbon then circulating automatically; in either event the flow of the hydro. carbon keeps the conductors clean. A further alternative consists in passing the hydrocarbon through tubes which themselves constitute the conductors and are protected on the outer surface against oxidation. The pressure may be adjusted as desired, but a reduced pressure is preferred. The example describes the decomposition of anthracene oils, the products consisting principally of hydrogen and acetylene and including small amounts of methane, ethylene, and carbon monoxide.

Title: Improvements relating to the neutralization of vapours emitted from liquid-filled electric apparatus
IPC: H01F27/14
Filed: 1950-04-26
Abstract: 667,534. Tanks. BRITISH THOMSONHOUSTON CO., Ltd. April 26, 1950 [May 11, 1949], No. 10293/50. Class 69 (i) [Also in Group XXXV] A sealed liquid containing tank has pressure relief means 2 comprising a frangible diaphragm 4, a cover 13 over the diaphragm which cover is caused to rise when the pressure on the diaphragm is excessive, a safety device to neutralise the gases released when the diaphragm ruptures, comprising a trigger 18 having one end 23 resting on the cover, upward movement of which causes movement of the trigger, an atomising device 27 having a source of fluid 35 connected thereto and means actuated by movement of the trigger to cause the atomising device to spray the fluid to neutralise the toxic effect of the released gases. When a pre-determined gas pressure occurs in a transformer tank a diaphragm 4 exerts a pressure on a cover 13 which tensions a pin 15 sufficiently to cause it to fracture at a relieved portion 17, thus releasing the cover 13 and allowing the diaphragm 4 to flex upwardly so that it contacts a knife edge 7 to facilitate the rupture of the diaphragm to release the enclosed gases. At the same time as the pin 15 fractures, a lever 18, having one end 23 resting-on the pin, is allowed to pivot so that the other end 25 moves out of supporting engagement with a piston 26 of an atomising device 27. The piston 26 normally supports a frangible diaphragm 29 against the pressure of a neutralising liquid 35 contained in a vessel 34. When the diaphragm 29 is unsupported the pressure of the liquid thereon is greater than it can withstand. The diaphragm 29 is thus ruptured permitting the liquid 35 to pass into the atomiser 27 from which it is sprayed through a nozzle 40 on to the escaping gases to neutralise the toxic effects thereof. Specification 546,839 is referred to.
