Abstract: PETITION, SPECIFICATION AND DECLARATION     To the Commissioner of Patents:     Your petitioners, Chen-Yen Cheng and Sing-Wang Cheng, citizens of United States and Taiwan respectively, and both residents of Albu-querque, New Mexico, whose post office addresses are both 9605 La Plava St., NE., Albuquerque, New Mexico,  87111 pray that letters patent may be granted to them as joint inventors for the improvement in method and apparatus for separating mixtures set forth in the follow-ing specification.     Specification of the Invention Title:    Separation of a Mixture by the Vacuum Freezing Vapor Desublimation Desublimate Vaporization Process ABSTRACT OF DISCLOSURE     The Vacuum Freezing Vapor Desublimation Desublimate Vaporization Process (denoted as VDDV Process) is an improved vacuum freezing process that is useful in separating solvent from a solution that contains one or more non-volatile solutes.  It can be used in desalination of sea water and brackish water, renovation of waste water, and concentration of aqueous and non-aqueous solutions Referring to sea water desalination, the process comprises the following steps: (a) feed sea water is flash vaporized under a reduced pressure to thereby form a first low pressure water vapor (3.5 torr) and an ice-brine slush;  (b) the first low pressure water vapor is cooled without pressurization to form a mass of desublimate ;  (c) the ice-brine slush is separated into a mass of purified ice and a con-centrated brine;  (d) the desublimate is melted and vaporized to form a second low pressure water vapor that is at a pressure higher than the triple point pressure of water (4.58 torr); (d) the second low pressure water vapor is brought in contact with the purified ice to thereby condense the vapor and melt the ice.  Both the condensate and the melt become product fresh water.  The characteristic feature of the process is that a low pressure vapor is pressurized from a first pres-sure that is lower than the triple point pressure to a second pressure that is higher than the triple point pressure by first desubliming the vapor and then melting and vaporizing the desublimate.  The need of a low pressure compressor has been eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE         A log-amp or log-ratio circuit for producing a temperature-independent output signal corresponding to the logarithm of the ratio of a pair of  input cur-rents.  The basic logarithm function is generated by a pair of opposed P-N junctions through which the respec-tive input currents flow.  Temperature compensation is effected by a circuit including a second pair of opposed P-N junctions which receive a PTAT current split between the junctions in accordance with a modulation factor pro-portional to the desired logarithmic function.  The tem-perature-induced signal variations produced by the PTAT current source are equal and opposite to the temperature-induced signal variations produced in the first pair of P-N junctions, and a temperature-independent output sig-nal is developed in accordance with the modulation factor applied to the PTAT current through the second pair of P-N junctions.

Abstract: DISSOLUTION OF METALS UTILIZING A GLYCOL ETHER                 ABSTRACT         Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and a cata-lytic amount of a glycol ether such as diethylene glycol butyl ether  or ethylene glycol butyl ether.           The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.                   BACKGROUND OF THE INVENTION           As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.    In the last few years, the industry has more and more turned to hydrogen peroxide-sulfuric acid systems for etching the electronic circuit boards, due to the low cost of the etching solu-tions and to the relative ease with which copper values can be recovered from the spent etch solutions.

Abstract: DRIFT ELIMINATOR FOR SERIES HYDRAULIC LIFT SYSTEM ON TILLAGE IMPLEMENTS AND THE LIKE            Abstract of the Invention The double-acting hydraulic cylinders of the lift system are connected in a master-slave series relationship.   When the cylinders have been re-tracted to a predetermined extent, a control valve between the last slave and a primary selector valve of the system is mechanically closed respon-sive to the arrival of the cylinders at such retracted  condition  and,   simultaneously,  the master is prevented from further retraction by either  mechanical  means  or  another  hydraulic control valve between the master and the primary selector valve.  Thus, the cylinders and their interconnecting lines are cut off from inadvertent overcharging, as well as fluid escape, so that all cylinders remain uniformly extended without drift from their established positions.  Several circuit arrangements  are  disclosed,  including  provision for bleeding off higher than necessary operating pressures tending to become trapped within the cylinders and their associated flow lines after the cylinders have reached the intended point of retraction.

Abstract: ABSTRACT     The application describes digital signal processing of radar video signals to provide an optimum display.  Three interacting components of the system are further described in detail:  a global mean estimating circuit, a statistical analyzer circuit, and a dynamic range compression circuit.          The global mean estimating circuit determines the mean of the amplitude distribution of video signals over a wide section of the display as opposed to a local mean of signals. , A local mean of signals is the mean of the amplitude distribution of video signals occurring in the near vicinity of a point on the display.  The statistical analyzer circuit evaluates the amplitude distribution of video signal samples and controls the gain of the signal path so that the variance of the sampled amplitude distribution follows the variance of a model distribution  The dynamic range compression circuit functions to compress the range of amplitude distribution in a manner to provide maximum information from the display.
