The system is intended to perform the local data acquisition and data processing works at a pipeline measuring station. The data acquisition part receives commonly used industrial 4–20 mA current loops, performs relatively slow quad slope A/D conversion with high common voltage and normal mode rejection to four BCD digits precision. The arithmetic processor is a cheap, calculator-like device, running to its own ROM. Each calculation subroutine is initiated by the 8085 master processor. Data exchange goes by means of a dual port CMOS RAM. Ease of software generation, even for complex calculations containing transcendental functions is emphasised. For man-machine interface convenience, BCD coding is maintained from data entry to display results.

In neutron time-of-flight spectrometry, the neutron energy uncertainty is proportional to Δt/t where Δt is the time-of-flight uncertainty and t is the time-of-flight.
This means that in most experiments the channel width of the time-of-flight analyser is allowed to increase with longer time-of-flight values without a reduction of the resolution.
Therefore a so-called accordion unit performing this function can considerably reduce the necessary handling and processing time of the experimental data.
The input words of 21 bit length can be compressed to 16 bit output words. The user can program the accordion unit by means of a CRT-terminal for 8 variable zones with optional compression factors up to 1024. The hardware is based on an Intel-8086 16 bit μ-processor system.

In the mass production of resistance spot welds for commercial use, several uncontrollable variables tend to produce welds of varying quality. We describe a microprocessing technique which is used with an infrared thermal sensing method to ensure weld uniformity. An optical fiber bundle “pipes” infrared radiation from a heated zone near the weld. A detection system provides a thermal signature of this zone, which reflects the progress of the heating inside the weld. A “standard” weld is made by trial and error, its thermal signature to serve as a model for all later welds of the same type. By controlling the welding-machine power in real time, the microprocessor ensure that all such welds will have the same thermal signature and, thus, the same quality.
