Abstract: ABSTRACT OF THE DISCLOSURE       Production of phosphorus-containing esters of the general formula   in which X stands for an alkyl group having from 1 to 3 carbon atoms, an aryl group or an alkoxy group having from 3 to 6 carbon atoms, Y stands for an alkoxy group having from 3 to 5 carbon atoms, and Z stands for a hydrogen atom, an alkyl group having from 1 to 3 carbon atoms or an aryl group by reacting phosphohalogen compounds of the general formula   in which A and B each stand independently of one another, for a chlorine or bromine atom, an alkyl group having from 1 to 3 carbon atoms or an aryl group, C stands for a chlorine or bromine atom, and D stands for a free pair of electrons or an oxygen atom with aliphatic alcohols having from 3 to 6 carbon atoms. The phosphorus-containing esters are made by mixing and thereby reacting in an unheated reaction zone in liquid phase the phosphohalogen compound with the aliphatic alcohol and delivering the resulting reaction mixture to the head of a steam-heated packed column; feeding the column's base portion with inert gas travelling upwardly therein countercurrently with respect to the reaction mixture; distilling off overhead hydrogen halide, alcohol in excess and, alkyl halide, if any, together with the inert gas; partially condensing and removing the distilled matter; and removing resulting phosphorus-containing ester flowing downwardly in the column from the column head to the column base, from the column base portion, if  ?sired in admixture with alcohol in excess.

Abstract: ABSTRACT          A valve mechanism adapted to produce a pressure which varies directly with the position of a mechanical member comprising a valve member having a control member movable within the valve member.  The valve member is hollow and is movable in a bore having pressure inlet, outlet and regulating ports, the inlet port being connected to a source of pressure.  The control member is movable within a bore in the valve member.  The valve member has a plurality of ports communicating with the ports in the bore and a spring urges the valve member in one direction.          The valve member has a differential land area thereon connected to the regulating port and thereby the outlet port and which urges the valve member in a direction in opposition to the spring in response to fluid pressure in the regulating port wherein the valve member will respond to the position of the control member when the control member establishes a connection between the inlet and outlet ports through the ports in the valve member whereby movement of said control member will be followed by said valve member and a pressure will be produced in said outlet port varying directly with movement of the control member.

Abstract: SINGLE AMPLIFIER  NETWORK FOR SIMULATING AN INDUCTOR by Man Shek Lee ABSTRACT OF THE DISCLOSURE        The one-port network here includes a pair of terminals and a single differential input operational amplifier having an output electrically connected through a resistor R3 to a first input of the amplifier, through a resistor R4 to a second input of the amplifier, through a resistor R7 to one terminal of the network, and through the series combination of the resistor R3 and a resistor R5 to the other terminal of the network which is also electrically connected to a ground reference potential. The second input of the amplifier is also connected to ground through a resistor R6. The first and second inputs of the amplifier are also electrically connected through the series combination of a resistor R1 and capacitor C1 and through a resistor R2, respectively, to the one network terminal. With the initial constraint that the conductance g7 of the resistor R7 satisfies the relationship     , where g corresponds to the conductance of an associated resistor, the impedance presented across the network terminals corresponds to that of the series combination of an inductor and a resistor. Proper selection of element values produces an impedance across the network terminals which corresponds to a single inductor, a single resistor, or an inductor in series combination with a resistor of which the simulated element values may be positive or negative.

Abstract: Abstract of the Disclosure The object of the present invention is a method for the separation and recovery of furfural and organic volatile acids from a vapour mixture obtained in the process of preparation of furfural.  According to the method, from a vapour mixture containing water vapour, furfural and organic acids and escaping from a reaction vessel operating on the counter flow principle, wherein the reaction to form furfural takes place, organic acids are separated and recovered before the vapour mixture is condensed and conducted to the furfural concentration process.  The separation is performed by absorbing the organic acids from the vapour mixture into the concentrated furfural solution in an absorption tower operating on the counter flow principle and by subsequently separating the furfural and organic acids from each other by means of vacuum distillation.
