Abstract: ABSTRACT OF THE DISCLOSURE           A unipotential electrostatic lens and method of oper-ation for charged particle beam tubes of the electron beam, com-pound fly's eye type having both coarse and fine deflection sections wherein the objective lens assembly may lack coaxial symmetry about the lens axis.  The unipotential lens comprises an assembly of axially aligned electrostatic lens elements with each lens element having an array of micro lenslet apertures and with each set of axially aligned micro lenslet apertures forming a micro lenslet.  Preferably, there are three such lens elements in the assembly with a high voltage excitation potential supplied to the center lens element.  A dynamic focus correction potential derived from the deflection potentials applied to the tube is supplied to the entrance outer lens element closest to the electron gun of the beam tube.  The remaining outer lens element is main-tained at system ground reference potential.  In preferred arrangements, a fixed offset potential is added to the high voltage excitation potential supplied to the center lens element  and a compensating offset potential is supplied to the entrance outer lens element along with the dynamic focusing correction potential to thereby distribute and minimize the effect of deflection sweep and astigmatism errors which otherwise might be introduced by the uncompensated dynamic focus correction potential.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for high volume distillation of impure liquid, particularly of binary mixtures of relatively low boiling organic substances and water, comprises fractionally distilling the impure liquid to form a vapor of a low boiling organic substance; compressing the vapor; passing at least a portion of the compressed vapor through a vapor composition adjustment zone wherein the organic substance may catalytically or otherwise react or merely stabilize following compression; compressing the vapor exit-ing the adjustment zone to form a recompressed vapor; cooling the recompressed vapor in heat transfer relation with the impure liquid whereby the vapor at least partially condenses, transferring sufficient heat to the impure liquid for evaporating the liquid and to form the aforementioned low boiling organic vapor; and collecting the condensed low boiling organic vapor.  In various embodiments of the invention the vapor exiting the adjustment zone may be expanded through an expansion engine and/or a portion of the compressed vapor may bypass the adjustment zone and/or the expansion engine and admix with the remainder of the vapor passing through the adjustment zone and/or expansion engine.  Work may be added to the expansion engine by mechanical means, such as motor means, drivingly linked to the engine, by admixing hot gases directly with the compressed vapor passing through the expansion engine, by a combination of direct mechanical drive and direct mixing of hot gases, or by other suitable means.     The method and apparatus are particularly suitable for producing substantially anhydrous ethyl alcohol.

Abstract: Case 2712 PROCESS CONTROL SYSTEM WITH SEGMENTED DOMAIN             ABSTRACT OF THE  DISCLOSURE   In a control system for use in controlling a variable process, the monitoring signal obtained from a process sensor is resolved into a plurality of signal components of higher frequency, each component being within a selected bandwidth. Feedback correction or modification is then applied to each signal component as required.  This feedback correction or modification is readily applied, owing to the greatly simplified form of the respective signal component, as compared with a complex control algorithm for the total combined signal in a prior system control function.  The respective feedback components may then be used directly in controlling relation with the process, or may be re-combined to provide a single control signal.  Additionally, the segmented signal system may be used in combination with a feed forward compensation circuit in order to lend an anticipation function to the control.  Also, predetermined transform functions may be incorporated in order to provide compensation for the effect of stronger corrective feedback of dominant components.

Abstract: A B S T R A C T            The invention relates to a method and apparatus for measuring at least one of the parameters flow rate, flow velocity, concentration and quantity of radon and/or radon daughters in the ground. The method is characterized by collecting gas arriving from the ground in a first chamber (12) which is gas-permeable at the bottom thereof, at least the downwardly extending boundaries (11) of the chamber being in contact with the ground, so that atmospheric gas is prevented from passing into the chamber. At least one detector (15) which measures alpha-radiation from the decomposition of radon and radon daughters is placed in a second chamber (16) communicating with the first chamber. Positioning of the second chamber and the detector is se-lected so that the detector can continuoulsy be observed and utilized for the measuring operation. The gas is allowed to pass continuously through the chambers (12, 16) over a given period of time, to expose the detector to the gas. Subsequent to this exposure, the measuring result registered on the detector is evaluated. The method can be modified for measuring radon departure from the surface of the ground, the gas-permeable first chamber being arranged over the surface of the ground to be analyzed. The detector is placed in a second chamber (16) communicating with the first chamber. For the purpose of measuring the flow rate and velocity of radon passing through the ground there is provided a first chamber (12) beneath the level of the ground, at a desired depth. This first chamber is connected with a gas-impermeable passage (13) to a second chamber (16) which can be readily reached from the level of the ground and which is sealed against penetration of atmospheric air. The detector (15) is placed in the second chamber (16).
