Title: Ship docking distance data monitoring display - has two sonar units on dock and includes signal acceptability circuit
Inventor: TOMLINSON PETER
IPC: G05D1/02
Filed: 1978-10-02
Abstract: A display system for ship docking data has two distance measurement units placed a distance apart along the dock driving a measurement circuit unit producing signals corresp. to the distance and/or speeds of ship sections to the docking points. The system automatically eliminates errors caused by sonar echo signal loss due to excessive docking angle or ship displacement along the dock. An error detection device monitors the derived signals which are accepted if the acceptability criteria are met. If they suddenly fail the test a value based on previous valid signals is substituted.

Patent DE-2848673-A1 (DE)
Inventor: MUTRUX CLAUDE
IPC: G04G21/00
Filed: 1978-11-09
Abstract: The invention relates to an electronic timepiece in which an input terminal of the integrated circuit is used as an output terminal. During the manufacturing of the timepiece it is important to check the running of the frequency of the oscillator and the operation of at least part of the frequency divider chain. However, in a timepiece, the places available for obtaining measurements could be very limited, and the timepiece does not generally have an output terminal adapted to connect the signal to be measured to an external counter. The purpose of the invention is to utilize an already existing input terminal as an output terminal for permitting a precise and rapid checking of the frequency of the oscillator by measuring, on that terminal, a signal of intermediate frequency delivered by the frequency divider chain. A decoupling circuit permits the terminal to be utilized as an output terminal because it is arranged such that a logic signal delivered to its input is transmitted to its output to the exclusion of the signal of intermediate frequency.

Title: Deoxidation of mild killed steel - forming spessartite which may be decanted by simultaneously adding cpds. of manganese, silicon and aluminium
Inventor: PALMAERS ALAIN
IPC: C21C7/06
Filed: 1979-03-31
Abstract: Method for deoxidising mild killed steels (C =0.15%) consists of measuring the amount of O2 dissolved in the molten steel bath before transferring it to the ladle, then forming inclusions consisting in the large majority of spessartite, which are as free as possible of Al2O3 and rhodonite, by adding to the bath a mixt. of materials which are carriers of Mn, Si and Al, esp. the corresponding ferroalloys. The steels-exhibit improved extrudability. The simultaneous addition of the three elements the individual disadvantages of adding them separately. Spessartite is more readily decantable than rhodointe. The dissolved oxygen level in equilibrium is less with spessartite than with rhodonite. Spessartite is liquid at 1195 degrees C with better cralescince than Al2O3, and it does not cause blockage of the nozzles of the continuous casting plant.
