Abstract: Abstract Elution of copper from chelating anion exchange resins wherein the first volumes of eluate obtained have very low copper contents.  The elution is conducted in an elution cycle which is applied to successive loaded batches of resin.  In each cycle the loaded resin is pre-treated with a low grade copper tertiary solution obtained as a process effluent from a preceding cycle.  Copper from the tertiary solution becomes loaded onto the resin.  The resin is then contacted with a secondary eluant, also obtained as an effluent from a preceding cycle.  The first fraction of effluent is stored for use as the tertiary solution in the next cycle and the second fraction is recovered as concentrated eluate.  The resin is then contacted with a primary eluant.  The first fraction of effluent is recovered as concentrated eluate and the second fraction is stored for use as secondary eluant in the next cycle.

Abstract: ABSTRACT OF THE DISCLOSURE     An implantable pacer having an effective stimulation rate which varies in response to a measured physiological parameter.  Changes in the parameter to be measured must be related to physiologically required changes in heart rate.  The level of oxygen within intracardiac or pulmonary artery venous blood is the preferred parameter.  This parameter is measured by an oxygen sensor located on a transvenously implanted lead.  As with normal demand pacers, a sensing electrode, also located on the lead, provides the pacer with an indication of whether a pacing pulse must be generated.          The measured physiological parameter determines the escape interval for demand pacing.  As such, a given minimum rate is determined for a given level of molecular oxygen in the intracardiac or pulmonary artery venous blood.  The technique is readily employed in both ventricular and  atrial-ventricular sequential modes.

Abstract: METHOD AND APPARATUS FOR LINEARIZING RATE ASSAYS                       Abstract A method and apparatus are described for the determination of rate reactions in a test liquid, where-in a detectable signal representative of the current status of the reaction is measured over plural times and the rate of change in the signal is ascertained.  The method and apparatus provide for the step of determining a value representing the signal produced by a reference liquid having a predetermined analyte concentration or activity, at the same plural times as are used to evaluate the test liquid, and using the value rep-resenting the reference signal at each of the plural times to arithmetically operate on the corresponding value obtained for the test liquid.  It has been found that the arithmetic operation step acts to make the rate reaction more readily determinable.

Abstract: REACTIVE DISTILLATION PROCESS FOR THE         PRODUCTION OF METHYL ACETATE         Abstract The present invention provides a process for the production of high purity methyl acetate from methanol and glacial acetic acid wherein the acetic acid functions both as a reactant and as an extractive agent. The process comprises countercurrently flowing approximately stoichiometric quantities of acetic acid and methanol through a single reactive distillation column in the presence of an acidic catalyst which is preferably sulfuric acid.  The column provides intimate contact between the acetic acid and the methanol and between the acetic acid and the azeo-tropes (methyl acetate/water and methyl acetate/methanol) which are formed in the column.  At preferred catalyst concentrations, the residence time in the column is at least about two hours.  The process further comprises continuously removing high purity methyl acetate from the top of the column and continuously removing water from the bottom of the column.  In preferred embodiments, the process further comprises removing intermediate boiling compounds, such as methyl propionate, methyl butyrate, isopropyl acetate, and mixtures thereof, from a vapor sidedraw stream.  The invention further comprises in preferred embodiments the use of a temperature control scheme whereby the overhead and the bottoms compositions are controlled by using two temperature control loops.

Abstract: ABSTRACT OF THE DISCLOSURE A desired feature is produced on a substrate by forming an adhesion inhibitor on the substrate adjacent the bounds of the feature being produced. A seedlayer is deposited over the adhesion inhibitor and exposed portions of the substrate, and a mask is formed over the seedlayer adjacent the edges of the adhesion layer to define the feature being produced.  A deposition material is deposited over the exposed seedlayer, and the mask is removed.  Unwanted portions of the seedlayer and deposition layer are removed by lifting off.  The adhesion inhibitor is removed, either by lifting off with the seedlayer and deposition layer, or subsequently.  The invention is particularly useful for the deposition forming thin film magnetic recording heads, and especially for the deposition of full wafers as opposed to individual small islands of pattern features.
