A method is provided for reducing measured data to representative coefficient values. The data relates to physical energy collected and measured by a physical sensor, and therefore, the measured data includes noise. In the method which may be carried out by programming a general purpose digital computer, the measured data values are first processed to remove the linear trend. The resultant values are then processed to provide the maximum number of coefficient values which represent the measured ...

The swapping function of input values to output values is performed through a pseudo content addressable memory which provides output values corresponding to a number E of n-bit input values, with E=2.sup.p -1. The pseudo content addressable memory is made of a plurality of cascaded random address memories 20 having at least a 2.sup.d addressing capability, with d higher than p. A control logic circuit is provided to store into each random access memory p-bits pointers, with each pointer being d...

A plurality of members, each constructed to produce a substantially constant current when energized, are disposed electrically in a matrix defined by a plurality of rows and a plurality of columns. A plurality of signals cumulatively represent a digital value. Each of the signals has logic levels respectively coding for binary "1" and binary "0" and each has an individual binary significance. The binary signals of intermediate binary significance are decoded to activate an individual rows. The b...

A process is provided for recovering cobalt values from a cobalt-N-acetyliminodiacetic acid complex by dissolving the complex in an aqueous solution of a strong acidic solution, extracting the acid solution with a hydrocarbon solvent containing a trialkylamine to transfer the cobalt from the aqueous solution into the hydrocarbon solvent, stripping the cobalt from the hydrocarbon solvent with water, and precipitating the cobalt from the stripping water by using a strong alkali.

The efficiency of an extraction process using a dialkyl phosphoric acid as an active extractant for separating extractable soluble metallic values from an aqueous solution is improved by the presence of a sufficient amount of a dialkyl naphthalene sulphonic acid as a modifier for the extractant.

This invention provides a process for the recovery of titanium values from a complex matrix comprising titanium nitride. The process comprises chlorinating the titanium nitride in the matrix to obtain a reaction product containing titanium chloride, and separating the titanium chloride from the reaction product. The invention also provides for the production of said complex matrix containing titanium nitride by nitriding titanium values in complex titanium-containing starting materials such as c...

A pipelined interpolator precomputes both integer and fractional portions of the slope of the function to be interpolated. The fractional portions of the starting value of the dependent variable to be incremented and the fractional value of the slope by which the increment occurs are each scaled to allow integer arithmetic. The scaled fractional portion of the starting value of the dependent variable is offset by a constant to allow carry-outs to be detected with the comparison "greater than or ...

There is disclosed an apparatus including the ensemble of a squaring means and an averaging means for the continuous measurement of RMS values which is especially useful for acoustical applications. A storage means in an averager is discharged by constant current which results in a linear discharge function of the averager so that quickly following input signals are no longer covered by the exponential discharge characteristic of the prior art detectors of this kind. The input signal is directly...

An apparatus for displaying or indicating the trend or amplitude of fluctuation of an analogically indicated scalar measurement comprising a substance layer on the scale surface of an indicator means, which substance visibly undergoes a reversible alteration with a change in environmental conditions, the reversion of the visible alteration displaying a time-delay when compared with the formation thereof, is described.

The invention is a process for recovering sulfur values from impure sulfur containing iron and sulfur chloride impurities in which a sulfur-sulfur chloride mixture is dissolved in a solvent, the solution is filtered to remove undissolved material, the sulfur is crystallized and then separated from the mother liquor.
