Abstract: Abstract of the Disclosure The oxidation promoting harmful effects of the presence of an alkaline catalyst in a polyoxyalkylene can be eliminated and the product made more resistant to oxidation especially at elevated temperatures by the incorporation therein of soluble salts of certain benzoic acid deriva-tives.  The soluble salts can be formed by reaction with the alkali or alkaline earth metal ion derived from the alkaline catalyst utilized in the polymerization of the polyoxy-alkylene.

Abstract: EQUALIZER ARRANGEMENT FOR MIXED-GAUGE CABLES     Abstract of the Disclosure An equalizer arrangement comprises a fixed-characteristic equalizer which is supplemented by a variable-amplitude notch equalizer to enable proper equalization of signals transmitted via cables of arbitrarily mixed cable gauges.  Automatic control of the notch amplitude is provided by detecting a predetermined signal level in the equalized signal, comparing this with its correct value, and con-trolling an up/down counter accordingly.  The count of the counter determines a current flow through a diode which constitutes a variable resistance of the equalizer.     - i -

Abstract: A METHOD OF RECOVERING VISCOUS PETROLEUM FROM A  SUBTERRANEAN, PETROLEUM-CONTAINING FORMATION            Abstract A method is described for recovering viscous petroleum from subterranean petroleum-containing formations penetrated by at least one injection well and by at least one production well, both wells being in fluid communication with the petroleum-containing formation.  The method comprises the steps of drilling and completing at least to the top of the petroleum-containing formation at least one intermediate well between the injection and production wells and in fluid communication with the petroleum-containing formation.  While the intermediate well is closed in, a hydrocarbon solvent having a specific gravity less than that of the formation petroleum is injected via the injection well into the lower part of the formation and, after the solvent is in place at the bottom of the petroleum-containing formation, pressure is applied to the injection and/or production wells and the intermediate well is opened thus enhancing the flow of the solvent from the bottom of the formation to the top.  Petroleum and solvent is then produced from the or each production well.

Abstract: METHOD FOR MANUFACTURING                   MICROPOROUS MEMBRANE                  ABSTRACT OF THE DISCLOSURE     The starting materials for the practice of the present invention are (1) one or more organic monomers or oligomers which upon ir-radiation very rapidly undergo a polymerization reaction to form a solid polymer; and (2) a liquid vehicle in which the one or more organic monomers or oligomers are soluble but in which the polymer formed is insoluble.  For the manu-facture of microporous membrane in accordance with the invention the monomers or oligomers are dissolved in the liquid vehicle, the result-ing solution is formed into a thin layer, and the thin layer of the solution is then irradiat-ed as with ultraviolet or electron beam radia-tion whereupon the rapid polymerization reaction immediately ensues and the polymer formed im-mediately segregates from the vehicle thereby resulting in microporous membrane from which the vehicle can be removed as by evaporation or washing.  Because the radiation-induced polymerization reaction and the segregation of the polymer formed are so rapid, the membrane formed has cells and communications there-between of very small dimensions thereby pro-viding the microporous structure.  Where ultra-violet radiation is used the solution also includes a photoinitiator.

Abstract: ABSTRACT           This invention reduces crosstalk interference components without a significant increase in recorded bandwidth of the modulated audio signals and without a significant degradation of the signal-to-noise ratio of the   reproduced   audio   signals.  According   to   the invention, the nominal carrier frequency of the modulated audio signals in adjacent tracks or scans is offset by an amount sufficient to shift the crosstalk interference components  outside  the  desired  audio  pass  band  for substantially all modulating amplitudes and frequencies.          At the same time, the modulated audio frequency spectra of the  adjacent  tracks  substantially  overlap  so that additional overall bandwith requirements are minimized.          A satisfactory offset from track to track is in the order of twice the maximum audio response frequency.  As the offset is reduced or as occasional high frequency high amplitude  audio occurs  in adjacent  tracks,  crosstalk distortion components will tend to appear beginning at the high frequencies.  Such crosstalk interference can be further  reduced  by  the  use  of  frequency  dependent compressor-expander  noise  reduction  because  of  the tendency of the interference to locate in one part of the audio band rather than across the entire audio band as in the case of no track-to-track carrier offset.
