Abstract: ABSTRACT      PROCESS FOR THE PRODUCTION OF BUTANE-1,4-DIOL     Butane-1,4-diol is produced by vapour phase hydrogenolysis of an alkyl ester of a C4 dicarboxylic acid, e.g. diethyl maleate, over a reduced Cu-Cr or Cu-Zn mixed oxide catalyst.  Two adiabatic hydrogenolysis zones are used.  The mixture exiting the first of these zones is cooled (by, for example, 5°C) and the resulting cooled mixture is fed to the second zone in which it re-equilibriates at a lower temperature to increase the butane-1,4-diol yield at the expense of gamma-butyrolactone.  Typical reaction conditions include use of temperatures of 150°C to 200°C, pressures of 25 to 70 bar, and an H2:ester molar ratio of 100:1 to 800:1.  When using a maleate ester it is often advantageous to hydrogenate this to the corresponding succinate ester in an upstream hydrogenation zone prior to entry to the first hydrogenolysis zone.

Abstract: Stripped Gold Plating Process Abstract A method for fabricating metallurgical contacts is disclosed for making thermocompression bonds to a metallized ceramic  substrate on which  semiconductor chips are to be mounted and electrically contacted. The method comprises placing a nickel layer on the metallized portion of the substrate and then covering the nickel with an immersion layer of gold.  The gold immersion layer is selectively removed from locations where thermocompression-bonded contacts are desired. Removal is accomplished by applying a chemical strip-per.  Heavy gold is electroplated on said locations and the assemblage is heat treated prior to placement of the thermocompression-bonded contacts.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention electronically identifies whether a computer module board is placed in the correct mechanical slot in a computer frame. A conductive line is connected to a least one electronic connector location in each mechanical slot in a computer frame. A computer module has open circuit electrical connectors which if put in the correct slot will mate with the locations in the slot in the frame which are connected to the conductive line. The other electrical connections which are used for identification are connected to a ground plane in the computer module board. A voltage source is connected through a resistor in a conductive line in the computer frame producing a high signal. If any computer module board engaged in a slot of the computer frame is in the incorrect slot, a low signal will be caused indicating the fault. The fault signal will be supplied to a power supply controller which prevents operating power from being provided to the computer boards.

Abstract: TWO DIMENSIONAL DIGITAL SPATIAL FILTER FOR ENCHANCEMENT OF POINT SOURCES            ABSTRACT OF THE DISCLOSURE           A point source spatial filter which determines the quality of a central point source or pixel under test to thereby detect point sources and minimize the signals from all sources other than the desired point source.  The spatial filter comprises buffer means for receiving pixel signals, memory means for storing pixel data for the test pixel and surrounding pixels, comparator means for comparing test pixel values against a given number of surrounding pixel values to determine if the test pixel is a local maximum or minimum value, subtraction means for subtracting the value of the nearest-valued surrounding pixel from the test pixel value where the test pixel is determined to be a local maximum or minimum, and means for indicating the difference between the value of the test pixel and that of the surrounding pixel of closest value.  This difference value becomes the filter output, and serves to establish a value for the point source signal intensity which is then compared to a threshold to provide a detection flag.

Abstract: "Carrier Recovery Circuitry Immune to Interburst Frequency Variations"               ABSTRACT OF THE DISCLOSURE       A carrier recovery circuit comprises first and second mixers for mixing a received PSK signal with first and second reference frequency signals.  A remodulator extracts a preamble from each burst of the PSK signal and supplies the extracted carrier to a carrier recovery means to cause it to derive a reference carrier from the extracted preamble.  A phase detector is connected to the outputs of the first and second mixers for detecting a phase difference between the PSK signal and the reference carrier, the detected phase difference being applied to a resettable noise reduction circuit for reducing amplitude fluctuations contained in the phase difference, the noise reduction circuit being arranged to be reset in response to each of the bursts to discharge energy stored as a result of the noise reduction and eliminate interburst phase errors which occur as a result of interburst frequency variations.  A variable phase shifter controls the phase of the reference carrier in accordance with the output of the noise eliminator and supplies quadrature versions of the phase controlled carrier to the first and second mixers as the first and second reference frequency signals.

Abstract: The density of a foam is controlled by measuring the electrical conductivity of the foam and adjusting its density in response to the measured electrical conductivity. Apparatus for carrying out this method comprises means (10) for generating a foam connected by an enclosed pathway (13) to an application outlet (14). Located within the pathway (13) is an electrical conductivity sensor (15) which is electronically connected (16) to a translation means (17). The translation means (17) is connected (18) to a gas glow controlling means (19) whereby, in response to the signal received from the conductivity sensor (15), the translation means (17) provides a signal to the gas glow control means (19) to vary gas supply to the means (10) for generating the foam. The invention provides an accurate method of controlling the density of the foam within a narrow range, thus enabling the application of the minimum amount of foam necessary to achieve the desired physical properties.

Abstract: At the end of their leaching, the rock salt cavities 4 contain a large quantity of brine 8 whose temperature is lower than that of the enclosing mass of earth 2. It is consequently not possible to seal them quickly because of the progressive expansion of the brine as it warms up. The process of the present invention makes it possible to shorten the period between the end of exploitation of the cavity and its abandonment from about thirty years to approximately two years. 
<??>It consists in injecting into the cavity 4 quantities of a mixture 12 which is denser than the brine 8 and capable of setting, while equivalent quantities of brine 8 are discharged at the surface to keep the cavity 4 open at the end of the complete filling of the cavity 4 with the mixture 12, while the creep of the rock salt 2 closes the shrinkage voids which have appeared during the setting of the mixture 12, and in then sealing the cavity 4. It is advantageous, for this purpose, to employ chiefly wastes to constitute the mixture 12.
