摘要： Voltage pulses, whose frequency represents the flow rate of a stream of oil well production fluids, generate a train of clock pulses. Each train of clocked pulses is characterized into a non-linear analog ramp and compared with a matching non-linear analog signal representative of the percentage of water in the oil/water mixture of production fluids. The comparison controls a gate to distribute each train of clocked pulses between two digital indicators.

摘要： A net oil computer which can gate out turbine meter pulses by producing gating pulses of time widths T.sub.o and/or T.sub.w directly proportional to percent oil, by volume, and/or percent water, by volume, respectively, flowing as a mixture in a pipeline, where ##EQU1## K is a constant, D.sub.M IS THE MEAN DENSITY OF THE MIXTURE,d.sub.w is the water density, andd.sub.o is the oil density.A densitometer provides the d.sub.m input. The water density does not vary significantly with temperature. A temperature probe can be used to compensate for changes in d.sub.o due to changes in temperature.

摘要： Apparatus which receives a train of electrical pulses from a particle analyzing device such as one which is operated in accordance with the Coulter principle, derives statistical indices from such train of pulses, stores the same in suitable storage means, receives a second train of pulses and derives the same indices from the second train of pulses, and compares the two indices. A readout device provides the comparison information. In this manner indices from one particulate system, such as for example a known sample, may be obtained and thereafter the same indices from an unknown sample may be obtained and compared with the indices from the known sample for study and analysis of the unknown particulate system.

摘要： Gas analysis apparatus comprising gas analyzers and calibration units, each having a variable characteristic, is adjusted by two steps. Firstly, the characteristics of the calibration units are modified to correct the analyzer output signals so as to compensate for drift in the analyzers. The modification of each unit is by independent zero and gain corrections. Secondly, the output signal of each unit is corrected according to the relation:

摘要： An output circuit is provided for use with a chromatographic analyzer. The analyzer output is amplified and passed through an attenuation network to an integrator. The output signal from the integrator is applied selectively through an amplifier to the input of the first amplifier to provide an automatic zero circuit. Additional differentiating, peak reading and storage circuits are selectively connected to the output of the integrator.

摘要： Electrical apparatus for obtaining density values for a filter pack for use with a production color film by comparing density values of a standard color film and its filter pack with the production color film, said apparatus having visual indicators for displaying the obtained net density values for the filter pack for the production color film. A computation circuit is electrically connected to the visual indicators and to a standard color film circuit and to a pack control circuit and to a production color film circuit for electrically processing signals from a plurality of potentiometers in the respective circuits. The signals correspond to density values associated with the respective item recorded therein whereby when the computation circuit is activated, numerical density values for the filter pack for the production color film are displayed by the visual indicators.

摘要： Color separation records are produced which are necessary to produce printers for printing color images by scanning an original copy. More particularly, printers are produced for reproducing color images with the use of color inks other than the standard inks. Black ink is used for the separation of color to substitute for the neutral color which is normally obtained by printing the standard three color inks one over the other.
