A satellite equipment panel on which may be mounted an installation equipment of a predetermined function, connectable by an interface, constitutes an artificial satellite. The satellite equipment panel includes a panel body, at least two interfaces for an interconnection to another satellite equipment panel, a line transfer switch disposed within the panel body for line transferring of the interconnection between the interfaces, wiring disposed within the panel body and connected at one end to one of the interfaces and at the other end to the line transfer switch for interconnecting the interfaces on that panel body. The interfaces and the wiring, in cooperation with a support structure, constitute a wiring module disposed within the panel body. The interface may comprise at least one of interfaces of electric communication, optical communication, and optical sensor.

A measuring apparatus for measuring a physical property of a substance using radiation has a source of radiation for irradiating the substance, a radiation detector which is disposed on the opposite side of the substance from the radiation source, a mask for allowing radiaton to enter the radiation detector only along n prescribed pathways, and a signal processing and calculating device for calculating the physical property of the substance based on the radiation which is incident upon the radiation detector. The mask has n different mask patterns each comprising a plurality of pattern elements which allow the passage of radiation and which can be positioned between the substance and the radiation detector in alignment with the radiation pathways.

Measurement apparatus employing radiation

An apparatus for determining the mass of each of the constituents of a substance to be measured, per unit volume of the same, is disclosed. The apparatus includes a detector disposed at the position to receive energy of back scattered photons produced by a radiation directed on a substance to be measured and systems of measurement, which are smaller in number by one than the kinds of the constituents under investigation, and the signal from the detector is processed for measuring intensity of the energy components unique to each of the constituents.

Apparatus for radiation analysis

The gas and water content of crude oil flowing through a pipeline is measured using a flow restriction in the pipeline, a radioactive source for providing separate radiation energies for each component to be measured, a detector for detecting the radiation transmitted by the various components to generate a first set of signals, pressure gauges upstream of and in the flow restriction for providing a second set of signals, and a signal processor for correlating the signals to provide mass flowrate values indicative of the relative proportions of the components of the mixture. The temperature of the mixture in the flow restriction can also be measured and fed to the signal processor for ensuring that accurate values of flowrate are obtained when temperatures vary.

Metering choke

A loop is constructed in which an output of a two-dimensional integrator is fed back through an exponential function unit for each pixel of a picture signal, a difference between the output and an input picture signal of the corresponding pixel of a next frame is taken and the difference is input to the corresponding element of the two-dimensional integrator, whereby relative standard deviations of quantum noise of an output picture are made constant at all positions of a screen.

System for making standard deviations in quantum noise constant

The invention is concerned with a digital ratemeter comprising a count difference circuit for adding input pulse signals and subtracting the frequency of the divider pulse, an integrator for integrating positive or negative count values from the count difference circuit, a feedback unit for receiving an integral count value from the integrator as input, thus generating a divider pulse frequency, and performing exponential transformation of the divider pulse frequency, whereby the integral count value is a count rate output and a fixed measurement accuracy in the overall range is attained.

Digital ratemeter

A fluorescent X-ray sulfur analyzer is disclosed and includes a radiation source for irradiating a sample with X-rays or .gamma.-rays, a radiation detector for detecting the radiation generated from the sample irradiated by the X-rays or .gamma.-rays and a first analyzer for selecting only fluorescent X-ray pulses from the output of the detector. The analyzer further includes a first pulse rate measuring device for measuring the pulse rate of the pulses selected by the first analyzer, a second analyzer for selecting only pulses of compton scattered rays from the output of the detector and a second pulse rate measuring device for measuring the pulse rate of the pulses selected by the second analyzer. An operational circuit is provided for operating the outputs of the first and second pulse rate measuring devices and is calibrated to compensate for the error caused by the variation of the carbon-hydrogen ratio to realize an accurate weight content of the sulfur in the sample.
