Two sources of frequently repeating flashes were considered: (1) a nource for Toepler schlieren photographs with a maximum space stabilized luminous volume in the shape of a short filamentary segment-, (2) a source for photographing objects in reflected light with maximum power and frequency of flashes. The first problem was solved most satisfactorily with a short capillary imp. The second problem teas solved with lamps having a large spherical bulb and a short discharge gap between the electrodes locat- ed inside the bulb. In addition, a rapidly deionizing multichawber hydrogen dis- Card 1/2 ACC NRo AT6001392 charger was constructed In order to provide for the commutation of the repeating high current discharges at the maximum frequencies at which the gas gaps of both types of flash lamps are unable to delonize and cannot themselven serve as the e tating element.

St,all 1957, NO-12, pp- 1082 - 1085 (USSR). ABSTRACT:' Operation of a:185-ton open hearth furnace fired with gas carburised.with fuel: oil is described. Originally designed and actually used gas-oil burners are shown in Figs. 1 and 2, respectively, and the gas installation used in-rig-3. --Ieor the,atomisation of the fuel oil, the use of gas and steam was tried. Operational indices of best heats and a comparison* of the furnace operation when fired with gas-fuel oil, gas-fuql oil (atomised with steam) and fuel oil alone are given in Tables 1 and 2, respectively. It is concluded that on transfer of furnace from oil to natural gas (10 atmt) firing the output will not decrease only if high pressure superheated steam is used for the atomisation of fuel oil. The flame obtained with natural gas, carburised with 25% of oil has similar properties a's fuel-oil flame. A proposal is made to carry out 'experiment's on firing an open hearth furnace with natural gas preheated to, 250-300 '0,,as well as with gas of increased pressure (13 15 0ard otm._).
