Abstract:
Modulated light containing components of two different wavelengths is transmitted over a path and the modulation phase difference at the receiving end of the path is determined. A common optical modulator is used for demodulating both of the received light components in order to minimize differences in phase between these two components.
Abstract:
Bearing arrangement for a rotor which is rotatable around a fixed axle and subjected to a varying axial load. This load is taken up by the magnetic repulsion between a magnetic element connected to the axle and a magnetic element connected to the rotor. The axial repulsion force between the magnetic elements is counteracted by an axial pressure in an axial contact seating whereby an increasing axial load on the rotor brings about an axial pressure in the contact seating which diminishes towards zero.
Abstract:
Device for the production of a uniform gas pressure for a plurality of pressure gas consumers. It comprises a tank divided by an intermediate wall into an equalizing chamber and a calming chamber. A gas inlet is attached to the equalizing chamber and it has a plugged tubular end a short distance away from the intermediate wall. The inlet is provided with several nozzles closely above the plug which nozzles direct gas flow against impingement surfaces placed opposite the intermediate wall in the equalizing chamber. The intermediate wall has openings for the gas passage to the calming chamber, which is provided with a gas outlet for each consumer.
Abstract:
An arrangement for creating voltages for aiming a gun, such as for lateral correction or correction of the elevation of the gun making use of the similarity between the charging or discharging function of a capacitor in a series circuit comprising a resistor and a capacitor and the required correction as a function of the firing range of the gun.
