Abstract: Abstract of the Disclosure A method of operating a pulverized coal furnace wherein the coal is introduced with minimal oxygen through an intermediate zone of the furnace which also has a relatively low oxygen content.          The carbon particles are projected into an upstream portion of the furnace where secondary air is introduced to burn the carbon particles.  The combustion products pass upwardly through the intermediate zone to a downstream zone where tertiary air is added to complete combustion.  This invention relates to burning of pulverized coal in a furnace and in particular to a method of introducing fuel and air into the furnace.

Abstract: Abstract A method of at least partially burning a hydrocarbon and/or car-bonaceous fuel, comprising at least partially burning the fuel in a flame provided by a burner, and laterally confining at least part (e.g. at least 50%) of the length of the flame (including the largest cross-sectional dimensions thereof) in a combustion chamber having cross-sectional dimensions smaller than those of the flame when not laterally confined in the combustion chamber so as to reduce the cross-sectional dimensions of the confined part of the flame by an amount of from 1.00 to 6.35 cms, but by less than 20% of the uncon-fined cross-sectional dimensions.  The lateral confinement of part of the flame by the combustion chamber causes reactive flame species to be reflected  and deflected back into the flame (rather than being lost therefrom or quenched) by the hot walls of the combustion chamber thereby reducing the amount of carbon and/or smoke in the gases leaving the combustion chamber.  Further improvements may be obtained by baffles in the laterally confined part of the flame which promote flame species recirculation.

Abstract: IMPROVED TIME BASE ERROR CORRECTING APPARATUS              ABSTRACT OF THE DISCLOSURE           Improved time base error correcting apparatus of the type wherein time base errors in a video signal, such as a video signal reproduced by a video signal playback device, are corrected.          The apparatus includes a main memory into which picture elements contained in each line interval of the video signal are written at a write-in rate that is synchronized with the time base infor-mation contained in that video signal, and from which the picture elements are read out at a reference rate.  A drop-out detector detects drop-out conditions which may occur in the video informa-tion and synchronizing information portions of the video signal.          Drop-out indications are stored in a drop-out  condition  memory so as to represent the positions within a line interval that drop-out has occurred.  These drop-out indications are written into and read out of the drop-out condition memory in synchronism with the writing in and reading out of picture elements from the main memory.          Each picture element read out from the main memory is supplied to a drop-out compensator which is responsive to a read out drop-out indication to replace a dropped out picture element that is read out from the main memory with the picture element which had been in the same relative position in the immediately preceding line interval.  A velocity error correcting device also is provided in order to correct velocity errors which may be present in each line interval.  In the event that a velocity error cannot be detected, for example, because drop-out has occurred in the synchronizing portion of a line interval, the velocity error which had been detected for the previous line interval is used again in this and then the next-following interval, i.e., for a total of three -i-consecutive line intervals.  An offset voltage is added to the velocity error correcting operation for this third line interval, except that this offset voltage is subtracted during a drop-out compensating operation in that third line interval.     -ii-

Abstract: Abstract Isolation of native petroleum surfactants for lowering interfacial tensions in aqueous-alkaline systems.           Petroleum of the type having reduced interfacial tensions with water at high pH is subjected to fractionation by distillation including distillation under vacuum in the temperature range of 100-200°C to recover a surfactant fraction of the petroleum distilled in that temperature range.  The fraction can be further concentrated by removing benzene-soluble components to obtain an ether-soluble residue having a density greater than water, The fraction alone, mixed with petroleum, or enriched with the residue, or the residue mixed with petroleum, can be injected as a slug into a subterranean oil reservoir to enhance tertiary recovery by alkaline water flooding.           The amenability of a reservoir for alpine flooding can be determined by separating the native surfactant fraction and measuring its interfacial tension with water at the proposed alkalinity of the floodwater.
